This study aims to explore the downstream pharmaceutical supply chain (PSC) and provides insight to the delivery process of medicines and associated operational inefficiencies.
An exploratory, qualitative approach was adopted to examine PSC inefficiency within two European contexts, namely, the UK and Greece. Data was gathered through interviews and a thematic analysis conducted to analyse the data and identify challenges faced by both supply chains(SCs).
The medicines delivery system needs to be enhanced in terms of quality, visibility, speed and cost to perform effectively. The findings demonstrated that although the healthcare SCs in the two European contexts have different operational structures, the results are in concordance with each other. Financial, communication, waste and complexity issues were the major concerns.
To the knowledge this is the first study to examine aspects of the medicines SC via a cross-case analysis in the UK and Greece and extends the body of knowledge. A broader sample of responses is warranted to further validate these findings.
The study outputs can inform pharmacies’ strategic to instigate targeted improvement interventions. The implications of which may be extrapolated further to other European healthcare organisations.
This research contributes to the academic literature by adding further theoretical insights to SC strategy development, especially those that have been characterised as highly complex. The study identifies four key areas of intervention needed within this SC (in both countries) to promote higher level efficiencies and effectiveness.

Healthcare organisations are responsible for promoting public health through improving the individual patient care experience in terms of quality, access and reliability. The efficient functioning of a healthcare system requires investments and constant improvement to be able to meet the increased demand for high quality services (Chassin, 2013). However, considering that healthcare costs, globally, are growing rapidly, there has been extensive pressure on healthcare organisations, especially on those where related expenditures represent a substantial proportion of the gross domestic product (GDP), to minimise their expenses without sacrificing service quality (Ferreira et al., 2018; Narayanamurthy et al., 2018); it is estimated that total worldwide drug expenditure in 2020 will be over US$1.4tn (Statista, 2018). In addition, the perceived high level of wastage associated with pharmaceuticals significantly increases this cost (Papalexi et al., 2015; Cherrett et al., 2012); US$13.3bn is the estimated global medical waste management market in 2020 (Medical Waste Management Market, 2018). Literature indicates that the implementation of effective supply chain (SC) practices offers solutions to healthcare organisations and assists in facing this challenge (Pohjosenperä et al., 2018; Bhakoo et al., 2012).
There is, therefore, a need for optimising the pharmaceutical supply chain (PSC) to achieve cost-saving, waste elimination and high-quality services. Uthayakumar and Priyan (2013, p. 52) defined the PSC as:
[…] the integration of all activities associated with the flow and transformation of drugs from raw materials through to the end-user, as well as associated information flows, through improved supply chain relationships to achieve a sustainable competitive advantage
There have been a number of reported documents and articles suggesting initiatives that can potentially improve the PSC. Reviewing the academic literature, scholars investigating the PSC found that certain benefits can be claimed, including effective inventory control (Bam et al., 2017; Pereira et al., 2014), improved information reliability (Chowdhury et al., 2016), firm innovativeness (Papalexi et al., 2015; Gölgeci and Ponomarov, 2015), organisational performance (Birkie et al., 2017), reduction of pharmaceutical waste and increased quality of healthcare services, (Pohjosenperä et al., 2018; Volland et al., 2017; Breen and Xie, 2015). Similarly, to the treatise within the academic literature, from a practical perspective, healthcare institutes such as the Department of Health (UK) and the national organisation for medicines (Greece) have outlined a series of guidelines aiming to determine how best practices can be adopted to enhance the delivery process (Department of Health (DoH), 2014; NOfM, 2016). However, healthcare organisations are facing difficulties in undertaking improvement initiatives, which explains why they have limited experience in adopting them, when compared with the industrial and retail sectors (Narayanamurthy et al., 2018). Brown et al. (2013) explained that the healthcare sector is different because healthcare services impact upon society and, as a result, the possibility of failure is not acceptable. Focussing on the PSC, the actual delivery process of medicines is lengthy and has been characterised as a more complex system than exists in other industries (Birkie et al., 2017; Mustaffa and Potter, 2009).
The literature has indicated many strategies for improving the performance of the PSC, but there is a noticeable gap in research on the comparison of the strategies applied within different geographical contexts and different domain focus of the PSC. To address this gap in the current academic research (Alvesson and Gabriel, 2013), this research aims to provide additional theoretical and practical insights (Baraldi et al., 2014) to the operational inefficiencies associated with the PSC used in two European countries, namely, the UK and Greece. It evaluates the challenges that pharmacies face when distributing medicines within this supply focussing specifically on impediments to effective delivery to customers and patients. An exploratory, qualitative approach was adopted and the following research question (RQ) was developed to focus the study methodology:
What are the challenges associated with the medicines delivery process within the downstream domain of the PSC in the UK and Greece?
This RQ yielded the following two sub-questions, namely:
What are the common operational issues observed within the downstream domain of the PSCs, which impact on medicines delivery?
What are the region-dependent operational issues observed within the downstream domain of the PSCs, which impact on medicines delivery?
Firstly, this paper investigates the PSC downstream domain to identify the factors that impact upon the system’s underperformance, which is a critical step for developing and improving the distribution of the finished products to customers (patients). The research focus will contribute to the lack of focus on the PSC downstream network in the existing literature, as reported by Narayana et al. (2014) and Bam et al. (2017) and extend the work of previous studies e.g. waste management (Xie and Breen, 2014); change management in healthcare (Burnes and Jackson, 2011); and inventory management (Bhakoo et al., 2012). According to Nicholson et al.’s (2018, p. 217) contribution conceptual framework, an incremental contribution is reached, which is measured against existing knowledge and develop further what is currently known. Secondly, there is a need to understand the medicines delivery strategies implemented in different geographical contexts, which might reinforce or contradict each other. Specifically, this research explores the downstream domain of the PSC applied within two diverse European countries, the UK and Greece to identify the common and region-dependent issues observed within the medicines delivery process; the countries selection criteria are presented in Section 3.1. This study has involved an interdisciplinary approach to ensure the accuracy and validity of design, analysis and outputs. While it has adopted a single lens of analysis [that of operations/supply chain management (SCM)], it has consulted with and involved researchers from both schools of pharmacy and schools of management (Zacharia et al., 2014). This interdisciplinary approach is characterised as a revelatory contribution by Nicholson et al. (2018). Indeed, Cheng et al. (2009) suggested that interdisciplinary research generates fruitful insight through integrating and combining concepts in a theoretical and practical contribution. To our best knowledge this aspect of the medicines SC via a cross-case analysis is underrepresented in the literature. The remainder of this paper is organised as follows. In Section 2, the relevant literature is presented arguing that complex systems such as the PSC, require well-established strategies to be managed effectively. Section 3 outlines the research method adopted to explore the subject under investigation. Subsequently, the findings section (Section 4) details the root-cause problems that are associated with the weak performances in both countries, which is a prerequisite for optimising the downstream domain of the PSC. This followed by Section 5, which discusses the contribution of this research; additional theoretical and practical insights are provided to SC strategy development, especially those that have been characterised as highly complex. Finally, conclusions and limitations of the study are, thereafter, presented in Section 6.
2. Literature review
Scholars have developed comprehensive insights into the concept of operational efficiency, providing a wealth of different definitions. It is agreed that operational efficiency is mainly connected to “doing the things right” (Førsund, 2017, p. 93). Operational efficiency can be measured by assessing the outcomes of the operation against the five key performance indicators, namely, quality, flexibility, speed (delivery), dependability and cost (Birkie et al., 2017). Efficiency measurement is dependent on the environmental context (Bamford et al., 2015). Focussing on the production of healthcare services, there is a need for improving healthcare efficiency with respect to the quality of service (quality), patient safety and satisfaction (flexibility, speed and dependability) and the cost of care (cost) (Guerrini et al., 2018). The increased pressure on healthcare organisations to reduce their pharmaceutical spending converts this need into an urgent one (Al-Balushi et al., 2014). Hoping to overcome the limitations of a function-based organisation, many healthcare organisations have adopted various improvement approaches (Bam et al., 2017). However, these approaches remain patchy and methodologically limited (Narayanamurthy et al., 2018; Bamford et al., 2015). Based on a thorough critical review of the extant literature in this area, a number of key issues that impact upon this underperformance have been identified and are presented in Table 1.
Although the PSC aims to meet customer demand effectively, which means patients should be able to access pharmaceutical products with ease, it is characterised as a complex enterprise because it has to deal with conflicting objectives and numerous intractable constraints (Birkie et al., 2017; Bam et al., 2017). A number of researchers have examined the PSC, concluding that there are several factors contributing to its inefficiency (Xie and Breen, 2012, 2014; Bhakoo et al., 2012). Table 2 summarises those factors, which are discussed in more detail below.
The inefficiency of medicine logistics is increased because of the involvement of numerous stakeholders within the PSC such as suppliers, pharmacists, physicians and management and clinical staff (de Vries and Huijsman, 2011). They have different roles and responsibilities within the PSC and often act as independent parties, without sharing the information required for producing healthcare services; weak information flow has been reported between the physicians and the pharmacy departments (Bhakoo et al., 2012). In addition, the fact that physicians act as the key decision-makers regarding the procurement of prescription medicines without having possessed an extensive knowledge of operations management (OM) and SCM practices and techniques increases the system’s underperformance (Bhakoo et al., 2012). Breen and Xie (2015) focussed on the role of pharmacists by exploring their critical management skills needed to perform effectively. Davies and Edwards (2013) highlighted that the continuous growth of the pharmacy sector (and the extended role of pharmacists (Greenwood et al., 2019)) requires more qualified pharmacists, without taking into account the lack of management modules during their degree. SCM skills are required when pharmacists are looking to improve the service quality (Uthayakumar and Priyan, 2013).
Institutional and regulatory pressures, which cause problems in determining accurate sales forecasts along with long developmental cycles of pharmaceutical products cause difficulties in applying supply chain strategies (SCS) (Bhakoo et al., 2012). There is difficulty in predicting the exact demand for medicines, partially due to the lack of standard nomenclature and partially because of the fact that medicines are stored in several areas of a healthcare organisation (Mustaffa and Potter, 2009). Similarly, it is challenging to predict the patient mix, understanding their needs and ultimately their supply consumption (Scheller and Smeltzer, 2006), specifically in emergency interventions. This unpredictable demand is one of the elements that force healthcare organisations to carry high levels of safety stock, avoiding uncertainties such as daily demand fluctuations and supply bottlenecks (Bhakoo et al., 2012). These practices could increase the level of waste observed within the PSC, which means that more expired or unwanted medication would have to be disposed of, raising the threat to the environment and human health (Wang et al., 2015). Medicines are expensive products that can be converted into dangerous or useless products for consumers due to their short expiration dates (Cherrett et al., 2012).
A main problem, therefore, facing this sector is process inefficiency related to pharmaceutical distribution. The current process inefficiency is caused by the use of basic but robust logistics and planning systems for pharmaceutical stock control; research suggests that existing systems use only simplistic push logistics (Jamali et al., 2010;). It is believed that standard logistics strategy models that have been useful in guiding managerial policy in other distribution industries are not easily applied to the PSC (Papalexi et al., 2015) due to the number of consumption points, the role and number of intermediaries and the long lead times and highly unpredictable nature of bio-pharma manufacturing, which have created a web of contingencies, interdependencies and uncertainties (Bhakoo et al., 2012). Figure 1 illustrates the structure of this complex SC including the PSC upstream, central and downstream domains where different groups of stakeholders are involved.
As Figure 1 illustrates, the PSC is not linear and there are many different distribution lines. For example, stakeholders involved within the upstream domain of the PSC could be either only pharmaceutical companies that produce the products or this domain could also include the distributor/wholesaler. The authors believe that the figure serves a useful purpose in demonstrating the complexity of the actual situation. Literature indicates that there is a low and fragmented focus on the PSC in research (Narayana et al., 2014), which is presented in Figure 1. Scholars tend to concentrate on the upstream business processes, revealing an emerging interest in exploring the interactions between pharmaceutical manufacturing and the R&D-specific biotechnology industry (Sen et al., 2013). This study will contribute to the existing lack of focus on the PSC downstream domain as it investigates the pharmaceutical delivery practices taking place within the UK and Greece.
The above factors impact upon the medicines logistics and prevent any improvement initiatives. Although, there is a wealth of research that investigates the inefficiency of medicine logistics (Bhakoo et al., 2012; Xie and Breen, 2014), the aim of this research is to extend the existing literature by investigating the PSC downstream domain in diverse European countries, UK and Greece. This will identify factors that impact on system underperformance (in service delivery) applied in both hospitals and community pharmacies. This study raises awareness of these factors for healthcare organisations to avoid them or opt to convert them to their advantage.
Figure 2 presents the key themes emerged from the literature review section, framed against the input-transformation-output operational model. This model considers the healthcare organisation as a production operation area that needs to be improved. This could be achieved by optimising the PSC though implementing improvement initiatives. However, as Figure 2 illustrates, a number of elements associated with the PSC in conjunction with particular aspects of improvement approaches influence the implementation of such interventions and as a result the system’s effectiveness.
3. Research methodology
3.1 Research context
The two countries involved in this research were, at the time of this study, members of the European Union (EU); as a result, both countries are subject to a large body of legislation that has been developed and supported by the 31 European Economic Area member states, the European Commission and the European Medicines Agency (EMA, 2014). These regulations are intended to ensure the quality, safety and efficacy of pharmaceutical products and promote the good functioning of the internal market (EC, 2015). Although the PSC in the UK and Greece operate under the same general regulations, there are some significant differences between them. Table 3 summarises the key figures for the UK and Greece.
Table 3 demonstrates that the two selected countries are different in size considering their population and GDP and in the total expenditure on healthcare – Organisation for Economic Co-operation and Development (OECD) Health Data (2018) suggested a positive relationship between GDP and health expenditure. However, Greece spent proportionally more on pharmaceuticals (26.3% health expenditure, in 2017) than the UK (11.4% health expenditure, in 2017). Besides, the healthcare system applied in the two selected contexts is different. The UK healthcare system emphasises on developing the primary healthcare settings to promote health and deal with disease at an early stage (Lionis et al., 2009). On the other hand, the Greek healthcare system focusses more on curative services (Souliotis and Lionis, 2005). This is supported by the fact that the share of public resource spent on healthcare in the UK is greater than that in Greece. In addition, the Greek healthcare system involves a higher ratio of physicians and a lower ratio of nurses that the UK healthcare system according to the statistics presented in Table 3.
Therefore, the striking differences between the two locations are the reasons for selecting them; there are differences between these two countries in terms of their healthcare spending and healthcare structure. For example, it is reasonable to suggest that the Greek healthcare system has been constantly affected by the economic crisis, which has caused remarkable reductions in Greek healthcare expenditure. This was not the case for the UK healthcare system, but there are still pressures put on it to minimise healthcare spending while improving healthcare quality. The authors were interested in investigating the complex pharmaceutical delivery process adopted and applied within the two diverse selected contexts. This exploration has enabled them to identify the similarities and differences between the two delivery systems and gain a better understanding of the downstream domains of the PSC in the European context. As a result, this study could contribute to developing a theoretical and empirical understanding of the broader perspective of the downstream domain of PSC norms that exist in the EU.
3.2 Research design
The research presents further empirical research into downstream domain of the PSC emphasising on specific geographical contexts, due to a dearth of informed research in this area. As a result of this, this study opts to adoption a qualitative, exploratory design to address the main and sub-RQs (Tukamuhabwa et al., 2017; Saunders et al., 2015). The qualitative approach adopted aims to gain a better understanding, appreciate the context and its singularities and explore the issues related to the downstream domain of the PSC. It allows the development insight about complex, real-life phenomena, which are difficult to be obtained by adopting different approaches such as an online survey (Ketokivi and Choi, 2014). This has been achieved by undertaking semi-structured research interviews (N = 22) with key pharmacy professionals within hospital and community pharmacies in two geographical areas, namely, the UK and Greece. The coding and data analysis, using Thematic Analysis, conclude that there are four themes, which are presented in the following findings section. Figure 3 presents in detail the sequence of activities undertaken to achieve the collection and analysis of the qualitative data.
3.2.1 Development of semi-structured interviews
Semi-structured research interviews were conducted to gather exhaustive and comprehensive information to explore the experiences, views and beliefs or motivations of individuals on the medicine delivery process in both Greece and the UK. As Figure 3 illustrates, the design of the interview protocol considered the operations and SCM theory and was informed by a preliminary analysis of the existing literature referring to the delivery process of medicines and the issues that have been observed within the downstream domain of the PSC that prevent effective delivery (this is presented in Section 2); the outputs of which identified key areas of exploration, which are the potential PSC issues. The interviews included a list of open-ended questions, which was divided into three parts:
the first part referred to general questions about the study phenomenon and the role of the interviewee therein;
the second part included specific questions regarding themes (e.g. the factors preventing an effective delivery process) identified by reviewing reports and previous research; and
the third part focussed on the interviewees’ personal views and beliefs on whether the perceived issues associated with the system inefficiency could be improved through implementing improvement approaches.
The list of the semi-structured interview questions is presented in the Appendix 1.
3.2.2 Selecting the target sample
Researchers select the sample that matches a number of criteria and best answers the RQs, meeting the research aims and objectives (Matthews and Ross, 2010). The target sample involves professionals working in hospital and community pharmacies in the two selected geographical areas. As the research aims to explore the downstream domain of the PSC, only those specialists who work within this domain could be considered as potential participants; therefore, a purposive sampling technique was adopted (Tongco, 2007). The exact number of pharmacists that operate within the particular study area is not available. There is only a general number of those professionals: Greece recorded a high number of professionally active pharmacists, at 104.9 per 100,000 inhabitants in 2016; this number in the UK, in 2016, was 86.2 per 100,000 inhabitants (Eurostat, 2018).
3.2.3 Qualitative data collection
In total, 22 semi-structured, face-to-face interviews lasting 1.5 h on average were undertaken; 16 semi-structured interviews were conducted in the UK and 6 semi-structured interviews took place in Greece. The authors acknowledge that the Greek sample is smaller compared to the UK one. The reason for this is that the authors are based on the UK and access was more readily facilitated because of this. While every attempt was made to engage more Greek participants (directly and via referrals), this proved to be challenging and unfruitful. However the Greek interviews did yield rich data, which was highly informative despite the small sample size. Those interviews provided data to generalise the qualitative research outputs, as the last interview did not add any consequential data. This ensured that the main research content was covered, and thus, the saturation level was reached (O’Reilly and Parker, 2012). Each interview was audio-taped and transcribed verbatim before the data analysis took place. A table that presents an overview of the interviewees’ characteristics is provided in the Appendix 2. It discloses information related to participants’ background, referring to their role, working experience, qualifications and the innovativeness of the delivery system in which they are involved, based on their perspective. This information adds value to the following analysis, as knowing the background of the interviewees could provide an insight into the participants’ reasoning or standpoint regarding some of their views on the phenomenon under investigation.
3.2.4 Analysis of the gathered data
A thematic analysis was conducted, which is a foundational method for analysing qualitative data (Guest et al., 2012). This tool enables researchers to identify, report and analyse themes within the collected data. Themes organise a group of repeating ideas, which allows researchers to answer the RQs (Vaismoradi et al., 2016). Braun and Clarke’s (2013) linear model was used to conduct the thematic analysis; their model includes six procedures:
Familiarisation with the data;
Generation of initial codes;
Searching for themes;
Defining and naming themes; and
Producing the final report.
In particular, having transcribed the recordings, a list of thematic codes was generated; this process was influenced by the conceptual framework, deductively informed by the literature review and the authors’ research interest. Basit (2003, p. 144) highlighted the importance of the coding process by stating that codes or categories are tags or labels for allocating units of meaning to the descriptive or inferential information compiled during a study. Each interview transcript was closely examined and coded manually using MS Excel; the authors acknowledge that the same process could have been delivered by using a software package such as NVivo. Computer software packages have been developed under a certain epistemology, which does not necessarily fit with the purposes of the study (Petty et al., 2012). For this reason, a systematic process of identifying the core themes that meet the research aims and objectives was conducted manually. The coding was done by one person but regular checks on the themes generated were completed by an additional researcher independently as an assurance check (Saldaña, 2013). Section 4 presents the findings emerged from the qualitative data analysis.
4. Findings – the analysis of the emergent themes
The qualitative data analysis revealed key factors that impact upon the effective delivery of medicines in the UK and Greece. Braun and Clarke’s (2013) linear model was used to conduct the thematic analysis; this was introduced in section three. These factors were categorised under four themes, which emerged from the data and literature and which are explained and justified more fully in the subsequent sections:
Waste issues; and
Other interesting data categories became evident during the process of identifying the core themes, but they were not in the immediate focus of this research, and thus, were not used. Of course, different data patterns could inspire future research. Each of the identified themes accompanied with evidence from the interviews are presented in Table 4.
4.1 Financial issues
The first theme is related to the financial issues that pharmacies have to deal with. The literature is rich in evidence revealing a pressure on healthcare organisations to minimise their expenditure (Al-Balushi et al., 2014). A critical issue identified was the high cost of the produced services. As 8/UK stated, clinical commissioning groups have extensively focussed on the drug expenditure. Trying to control their pharmaceutical spending, specific budgets are allocated to each healthcare organisation; 7/UK explained, we manage and supply approximately £40m of medication per annum. 18/Gr explained that we cannot spend more than the budget that has been allocated for us, which is approximately €30m per annum. In a similar vein, community pharmacies have to carefully manage the complex pharmaceutical delivery system to be able to predict the demand, satisfy their customers and control their expenses. The budget spent on pharmaceutical depends on the business size and the market demand. For example, according to 16/Gr, a medium size community pharmacy in Greece spend approximately 500,000€per annum.
Healthcare organisations in the UK, try to keep the patients at the primary health care level and this has been considered a way of reducing the cost of services. 12/UK explained that there is a big push to reduce the demand for secondary healthcare service because they are expensive. There is a slightly different view in healthcare organisations in Greece; they tend to keep patients in hospital to avoid any risks associated with their health, although they acknowledge that this practice is too expensive, as 14/Gr explained. Based on the qualitative data, a “home care practice” has not been adopted by the Greek healthcare system, which might be the reason for a longer hospital treatment. Furthermore, when the interviewees were asked about the adoption of improvement interventions, the majority of them agreed that any improvement requires new investments, which are not available (e.g. 15/Gr and 2/UK).
4.2 Communication issues
Communication issues emerged as another important factor that could influence the accurate delivery of medicines; the existence of fragmentation and duplication in services has been reported (Bamford et al., 2015). Specifically, the communication between the different stakeholders involved within the PSC is weak. A UK pharmacist (11/UK) stated that there is often lack of communication between secondary care and primary care, which contributes to the generation of duplication in services. A Greek pharmacist (17/Gr) commented on this expressing a different point of view; sometimes there is not enough information provided in a prescription, which makes us unable to deliver it, so we have to contact the doctors asking for additional information. Besides the miscommunication between the prescribers or between them and the pharmacists, there are similar incidents between pharmacies and their suppliers. 23/UK explained that it is really hard to contact our supplier if we need any additional information; it is often a time-consuming process, which might raise the risk of losing customers or making them unsatisfied (e.g. 16/Gr and 1/UK).
The communication issues that the community pharmacies have to deal with have been described, thus, far, however in hospital pharmacies the situation is slightly different. A UK hospital pharmacist (4/UK) stated that:
[…] one of our main problems is that the medication does not follow the patient. This process is associated with two types of miscommunication: i) if the drugs do not get to the accident and emergency assessment units in time and patients have been sent to another ward, they will end up having those drugs re-ordered; and ii) even if the medication has been delivered to those units on time, patients may need to move to another ward without taking their medicines with them, which again causes double ordering.
Besides the patient self-medication, which is the drugs that have been prescribed for a particular patient, the wards stock some medicines, in the ward cupboards, for general use. A Greek hospital pharmacist (14/Gr), stated that nurses from a different department often come to the pharmacy asking for products without having checked their availability in the ward cupboards. Therefore, miscommunication between the staff not only increases the level of wastage but also increases the time spent to distribute the correct medicines or ascertain their availability. In addition, healthcare providers in both selected countries tend to operate independently, without perceiving that they are part of a wider service process. For example, doctors might change the prescription without informing pharmacists (e.g. 18/Gr and 4/UK). Those actions generate delays and waste during the service production, which increases inefficiency and associated cost.
4.3 Waste issues
The third theme preventing the effective and efficient delivery of medicines relates to the level of wastage that exists within the PSC. Uthayakumar and Priyan (2013, p. 52) highlighted that:
Pharmaceutical products can be expensive to purchase and distribute, but shortages of essential medicines, improper use of medicines, and spending on unnecessary or low-quality medicines also have a high cost in terms of wasted resources and preventable illness and death.
Community pharmacists believe that the reason for the high level of wastage derives from the existing system itself; it is related to the way clinicians prescribe and patients’ attitude; a Greek community pharmacist (19/Gr) explained that patients often do not follow their medication, which generates waste. Based on the pharmacists’ opinion (e.g. 16/Gr, 17/Gr and 19/Gr), patients in Greece tend to ask for more medication, by visiting different doctors, until they find what they think works for them and on the other hand, different doctors tend to prescribe different medication; the one that they believe it will best treat their patients. Similarly, UK community pharmacists (e.g. 22/UK and 10/UK) believe that the waste is generated by the system; people tend to buy their prescription, use it until they feel better and then keep it in their cupboard for future use, but they end up storing many expired medicines (e.g. 17/Gr).
Besides community pharmacists’ opinion, hospital pharmacists believe that the main waste derives from the poor communication and the lack of synchronisation between the pharmacy and the wards. Specifically, 6/UK explained that:
[…] the main waste comes from the wards; medication is returned to the pharmacy on a daily basis […] either because the treatment has changed or because patients left the hospital, without having taken their medication with them.
This medication generates waste because it has to be destroyed as it has been used or ordered for a particular patient as 4/UK reported. Another type of waste arises from some lines/types of medicines that have to be stored in the pharmacy according to the guidance from the General Pharmaceutical Council. 2/UK explained that:
[…] we have to keep in some type of medicines, such as antidotes for poisoning, just in case they are needed. However, we rarely use them and as a result they often go out of date.
Similarly, the medicines included in the emergency drugs boxes can easily go out of date as they are not used frequently but they have to be kept according to the national guidance. Hospital pharmacies acknowledge the high level of wastage that exists within hospitals and for this reason they have introduced green bins; these are lockable boxes in which leftover or unusable medicines are put. However, according to 5/UK, separating the medicines that can be reused from those that have to be destroyed is a time-consuming process:
[…] we have to make sure that these medicines can be reused, some of them might be unlabelled and according to the guidance from the General Pharmaceutical Council, we cannot re-use them until we have correctly identified them.
4.4 Complexity issues
The final theme emerging from the analysis is the perceived complexity issues of the delivery system. A group of scholars suggested that the PSC are more complex compared to SCs in other sectors (Greenhalgh et al., 2012). The type of services offered is enough to represent the level of complexity within this system; 8/UK stated, we have to deal with not only sensitive products but also very expensive ones. It is generally accepted that medicines can be converted into dangerous or useless products for consumers; based on this assumption, Within the PSC there are different distribution lines; they cannot treat all the products that they manage in the same way. 15/Gr reported:
[…] we store our products differently based on their frequency of use; we want to have easy access to those that are immediately consumed and of course this influences how frequently we order them.
8/UK reiterated this, explaining that the system requires an excellent relationship with our suppliers including a high level of trust.
Hospital pharmacies in both countries tend to receive their medicine supplies twice per day; they have set up a contract with a couple of big wholesalers, which enable them to negotiate the prices and get a better offer. On the other hand, community pharmacies are not in a privileged position where they can set up contracts with their suppliers, but they tend to create collaborations between them or alternatively have their own wholesaler company and supply their stores. In particular, in Greece there are 27 organisations founded by groups of cooperative pharmacists, operating within a particular region. These organisations operate as warehouses; they locate close to their members, which creates flexibility, enabling them to deliver the products on time. In the UK, community pharmacies tend to be big companies with many stores all over the country. They run their own warehouse, which also allow them to get some good deals from the pharmaceutical companies, as 9/UK explained.
The complexity of the system is not only created from the suppliers but also the existence of multiple stakeholders, as Figure 1 illustrates, also impacts upon the distribution of medicines. Especially, in the PSC there are numerous stakeholders who are responsible for the delivery of medicines such as general practitioners (GPs), nurse practitioners (NPs), secondary care doctors and pharmacists. In the UK all of them can prescribe medication or advise patients. On the other hand, in Greece nurses have not been trained to prescribe medication, which is something that only doctors are qualified to do.
In summary, four main sources of operational inefficiency were identified. The issues related to these four themes have been discussed and analysed based on the interviewees’ answers. Table 5 presents the qualitative findings, highlighting the main sources of operational inefficiency in the PSC.
To provide clarity to the discussion this section has been arranged around two core areas, namely:
The common issues observed within the downstream domain of the PSC; and
The region-dependent issues observed within the downstream domain of the PSC, which engages with the findings and literature around the UK and Greece contexts.
5.1 The common issues observed within the downstream domain of the pharmaceutical supply chain
As indicated from the literature and confirmed from the data analysis of this study, healthcare organisations have to deal with a number of SC issues when they attempt to produce their services such as financial, complexity, cultural and communication issues (Xie and Breen, 2012; Davies and Edwards, 2013). These issues influence the healthcare service quality and in particular prevent an efficient and effective delivery process (Chassin, 2013). Al-Balushi et al. (2014) stated that constant external pressures impel healthcare organisations to undertake operational changes to minimise their pharmaceutical spending.
The limited financial resources available for healthcare organisation in both countries have acted as a barrier in undertaking any improvements. Pharmacists in both countries assume that the implementation of any new or significantly improved delivery practices requires a particular investment, which cannot be supported by the healthcare organisation as there is no additional funding for them. They seem to be reluctant to undertake any changes because they believe that they are costly and risky. Organisations’ financial resources need to support any improvement interventions (Davenport, 2013); the absence of funding might lead those activities to be abandoned or not be completed (Archibugi et al., 2013). “During a crisis, many firms might focus more strongly on survival and less on seeking out new opportunities” (Archibugi et al., 2013, p. 306). However, there are a number of initiatives that can be undertaken that require less or no financial investment and are still able to improve organisations’ performance such as Lean thinking or Reverse Logistics (Weingart et al., 2012).
The data analysis demonstrated that in both European contexts, the weak communication and stakeholder synchronisation, undermines the effective performance of the PSC. The main root-cause of the perceived miscommunication is associated with the low level of transparency during the delivery process. This fact could be explained based on the significant gap existing between doctors, nurses and pharmacists’ perceptions of their roles in producing healthcare services, including their different attitudes towards teamwork (Maddox et al., 2016). Akhtar et al. (2012) highlighted the importance of teamwork development for improving service effectiveness and achieving the organisation’s success. Hwang and Rho (2014) stated that successful SCM requires systematic and strategic management of collaboration, information and knowledge, which fits with the particular political, social and cultural context. Hwang and Rho (2014) explained that actors of SCs have to invest in relationships between them, which could result in benefits of knowledge transfer, information sharing and the establishment of common strategies to explore and exploit potential opportunities.
The analysis of the data found that the level of wastage is high, which causes inefficiency within the pharmaceutical delivery system. The critical role of pharmaceuticals in human health forces pharmacies to retain a large inventory of stock, which increase the risk of generating waste (Bhakoo et al., 2012). One current example of this in practice is the uncertainty surrounding Brexit negotiations in the UK and the potential for panic stockpiling across this SC (Kwon, 2018). In addition, functional rules derived from the particular legal context are evidence of the relatively centralised environment of healthcare organisations (Bamford et al., 2015), which does not allow pharmacists to operate independently and fully control their storage (Papalexi et al., 2015). These practices cause considerable operational problems such as the expiry of medicinal products stored for a long time or critical drug shortages (Kostagiolas et al., 2008). Besides, the data analysis concluded that waste within the PSC is generated due to the lack of communication and synchronisation between the PSC stakeholders. Hospital pharmacists operating in both geographical areas explained that the main waste comes from the wards, either due to the perceived discontinuity in services or due to the poor information sharing between the clinical staff and pharmacists. This matches with the previous literature supporting that physicians tend not to inform pharmacies when they have ceased to prescribe medicines for a particular ailment (Bhakoo et al., 2012). Although, according to Liu and D’Aunno (2011), developing collaborations among health professionals has been considered as one of the most effective strategies to manage patient care, challenges such as misunderstandings of each other’s role, differing perceptions towards collaboration (Schadewaldt et al., 2014) and the existence of hierarchical structures (Schadewaldt et al., 2014), need to be faced.
Furthermore, community pharmacies, in both European contexts, believe that the waste within the PSC derives from the healthcare system. This is in line with published reports identifying root causes of medicine waste, encompassing:
[…] patients recovering before their dispensed medicines have all been taken; therapies being stopped or changed because of unwanted side effects; patients’ deaths; and factors relating to repeat prescribing and dispensing processes. (DoH, 2011, p. 6)
Kongar et al. (2014) suggested, that most of the time, the spare medicines are not returned into the system. Those products can be converted into dangerous or useless products; a fact that has raised significant concerns for potential threat to ecological environment and human health (Department of Health (DoH), 2014). Wang et al. (2015) stated that there are evidence revealing that pharmaceuticals have been detected in various environmental compartments such as surface water and groundwater. For this reason, the EU, in 2011, developed a public awareness campaign aiming to reduce the impact on the health and environment generated by hazardous waste, including expired or unwanted medicines, through their safe disposal (Kongar et al., 2014).
Attempts to explain the complexity of the delivery system concluded that, from an operations point of view, the use of simplistic push logistics might be the answer to the current process inefficiency. Jamali et al. (2010) explained that a push-based SC is based on forecast demand, which provides direction on the quantity and type of products that need to be stored. However, Bhakoo et al. (2012) suggested that within the PSC, high demand uncertainty has been observed, not only because of the nature of the pharmaceutical products but also because of the existence of the institutional and regulatory pressures.
Furthermore, Scheller and Smeltzer (2006) reported that physicians’ knowledge regarding OM and SCM practices is limited, which increases the complexity of the delivery system. Although clinicians’ role is to focus on patients care rather than administrative functions, critical management skills are required to deliver high quality services (Breen and Xie, 2015). Uthayakumar and Priyan (2013) suggested that these skills could solve inventory management problems and as a result improve the healthcare operations. It is apparent, therefore, that the stakeholders involved within the PSC require expert knowledge to be able to best use the healthcare organisational resources, avoid the duplication in services and as a result improve customer satisfaction (Radnor et al., 2012).
The availability and quality of medicines do not rely only on the pharmacists’ ability to manage them properly but also on the role of suppliers; the availability and quality are based on how frequently they deliver the required products. According to Hakansson et al. (2009), managing the relationships between organisations and their suppliers is critical for the SCM because this influences the organisations’ performance.
From the analysis of the data, it was established that a number of similar issues have been observed in the pharmaceutical delivery systems implemented within the two diverse contexts (UK and Greece). These issues cause considerable operations problems, preventing an effective and efficient PSC. Figure 4 presents the emerging sources of inefficiency, which are associated with the four primary themes, namely:
By discussing those issues, it became apparent that there is a multi-dimensional relationship between an issue and a theme. For example, the lack of synchronisation and continuity of services primarily emerged as a communication issue; however, it also increased the complexity of the system and impacted on the level of wastage. In Figure 4, the wider dashed line represents the relationship between the themes and the solid lines present the relationship between the issues. The complexity of relationships is potentially different amongst the solid arrows, but it is very difficult to illustrate with confidence between the perceived issues and the presented weight of importance. The figure does, however, provide a visual indication based on the qualitative data and analysis.
5.2 The region-dependent issues observed within the downstream domain of the pharmaceutical supply chain
The healthcare system in the UK has had significant financial and infrastructural development over the past decade. This has facilitated provision of services closer to patients’ homes; therefore, the demand on hospital outpatient departments has been reduced. For this practice to be implemented successfully, the national health service (NHS) in the UK has educated the clinical staff such as the NPs, to be able to assess patients’ condition and prescribe medication (Gielen et al., 2014). As Kroezen et al. (2011) explained, the introduction of nurse prescribing was aimed at improving the access quality and continuity of care. However, Sandø et al. (2010) highlighted that the existence of multiple prescribers within the UK healthcare system increases the complexity of the pharmaceuticals delivery process and the higher potential of medicines waste.
The Department of Health (2011, p. 6) reported that one of the main root causes of medicine waste derived from therapies being stopped or changed because of ineffectiveness and side effects, which is one of the reasons why medicine optimisation is such a huge agenda. The waste of pharmaceutical products might be generated not only because treatments are changed because of the prescribers’ different opinions (Sandø et al., 2010) but also because of patients’ attitude. Nunes et al. (2009) found that approximately one-half of the medication prescribed for long-term conditions is not taken as recommended. Patients, therefore, sometimes decide not to follow the guidelines provided, either because they feel better or they believe the medication is not appropriate for their condition. Considering the lack of communication and synchronisation existing between the PSC stakeholders and in particular between the physicians and the clinical staff (Bhakoo et al., 2012), one could appreciate the communication issues occurring due to the involvement of multiple prescribers in the system. As detailed above, this also generates financial and waste issues because providing different medication means that patients need to buy different medicines and that the spare medication is no longer useful.
Focussing on the Greek healthcare system, only physicians can prescribe medication, which reveals a rather fragmented and centralised system. Considering that the Greek healthcare system involves one of the highest ratios of physicians and one of the lowest ratios of nurses in Europe, one could conclude that the emphasis has been placed on curative services rather than disease prevention, health promotion and home care services, which is something supported by Lionis et al. (2009). As the NHS in Greece has not developed a well-established primary care, patients tend to trust more the private primary care providers. Lionis et al. (2009, p. 2) stated that “the Greek healthcare system is one of the most privatised among EU countries”. In 2017, the private expenditure of overall health spending in Greece, accounted for 39% (OECD Health Data, 2019); this percentage is double that (21%) covering the relative services produced in the UK (OECD Health Data, 2019). According to Theodorou et al. (2009), this practice has greatly contributed to the discontinuity of healthcare services because patients are free to select and consult with any specialist, who may provide different guidelines. Therefore, although there is only one type of prescribers, high level of wastage is still generated (Pappa and Niakas, 2006). Gress et al. (2006) suggested that the non-existence of family physicians serving as gatekeepers to more specialised care and the miscommunication between the healthcare providers, increases spending on pharmaceuticals and associated waste. This is because more medicines are likely to be prescribed and therapies stopped or changed. The pharmaceuticals delivery process, therefore, is characterised as highly complex, similar to the UK delivery system; however, this complexity is generated by applying different practices.
As can be concluded from Table 6, although the UK and Greek healthcare systems have been structured in a different manner, based on the available resources and capacity, the issues emerging are similar and related to the primary themes identified:
One could conclude that the issues related to systems do not stem from the system itself but from the way of managing it. Brandon-Jones et al. (2014) suggested that orchestrating resources and capabilities across the SC could be very challenging, but at the same time creates opportunities of developing an effective system. For example, the primary care provision can be developed within the Greek healthcare system implementing a GP’s practice for the identified issues to be overcome (Lionis et al., 2009). Although developing the primary care provision can lead to less expensive healthcare services through better controlling the overall healthcare costs (Ansari et al., 2003), maintaining a strong primary care structure requires great investments (Rosano et al., 2011). Therefore, this initiative has to fit with the Greek context, considering the Greek healthcare organisations’ characteristics to be successfully implemented. Similarly, improvements within UK primary care have to be undertaken based on the available sources and capabilities. Barney (2015), who focussed on organisational systems’ effectiveness, suggested that internal weaknesses and external threats can be avoided through establishing strategies that fit with organisations’ environmental conditions.
The aim of this research was to assess the downstream domain of the PSC taken place within the UK and Greece; the identified issues could be considered for innovative approaches to be implemented aiming to improve the medicine delivery system. Although, there is a wealth of research that explores PSC management and strategy, few studies have been reported in the literature, which adopts a focussed approach on downstream PSC activity and also as a cross-case comparative analysis. In this study, there is an incremental and revelatory contribution (Nicholson et al., 2018) as it attempts to rectify this imbalance and there are four key outputs as follows:
This study fills the gap in literature on the subject of SCM not only in hospitals but also in community pharmacies operating in two different geographical areas, the UK and Greece. Specifically, this research extends the work of previous studies e.g. conducted by Xie and Breen (2014) on waste management; Bhakoo et al. (2012) on inventory management; and Burnes and Jackson (2011) on change management in healthcare;
It also contributes to the academic literature by investigating the downstream domain of the PSC, using hospital and community pharmacies as the focal organisations. Previous research examining the aspect of PSC mainly focussed on the upstream domain of the PSC that includes the pharmaceutical manufacturers (Narayana et al., 2014). Figure 1 provides a conceptual model of the PSC domains and identifies the number of stakeholders involved in them;
The current research summarises the key issues related to the PSC inefficiency reported in the existing relevant literature, which are represented by Figure 2 and identifies 4 key areas inefficiency that impact upon both the UK and Greek PSCs: 1. financial, 2. communication, 3. waste and 4. complexity issues. In addition, the paper highlights the common issues observed in both selected countries, which provides a more clarity to the pharmaceutical delivery process applied in the European context, allowing the generalisation of the research findings; and the region-dependent issues, which can be considered by each country to avoid ineffective practices; and
This paper provides more information regarding the practices involved with the downstream domain of the PSC highlighting the areas that require improvements. This information can help healthcare organisations to address a critical issue for academics and practitioners, which is related to the challenge of how healthcare organisations could be more productive, whilst using fewer resources (Mustaffa and Potter, 2009; Xie and Breen, 2012; Al-Balushi et al., 2014).
6.1 Practical implications
This research is exploratory in nature and provides further theoretical insights to SC strategy development. Its results identified four key areas of intervention needed within the downstream PSC. These results potentially assist hospital and community pharmacists to understand the operational inefficiencies that they have to face and directs them towards suitable innovative solutions that could enable them to increase levels of efficiency and effectiveness. This research examines the healthcare SCs in two European contexts, the study’s outputs, therefore, provide information regarding ineffective practices or best delivery practices implemented in the UK and Greece – a knowledge exchange contribution between the two countries. Finally, the paper highlights the practices within the medicines delivery process that require improvements; those, which could help healthcare organisations to address a critical issue for academics and practitioners, namely the challenge of how healthcare organisations could be more productive using fewer resources (Mustaffa and Potter, 2009; Xie and Breen, 2012; Al-Balushi et al., 2014).
One of the major challenges faced while conducting this research was related to accessing the required data. Considering that professionals working within the PSC have a relatively heavy work load, a number of the potential participants were reluctant to be involved in this research. In addition to this, the study focusses only on the downstream domain of the PSC, which excludes those specialists operating within the upstream and central PSC domain. Another obstacle faced particularly during the data collection was related to the geographical distance; the authors approached only the potential participants that could be reached, thus the difference in responses rates between the UK and Greek sample. Finally, the last limitation of this research stemmed from the way that the data analysis was conducted. The thematic analysis undertaken was driven by the literature review and the authors’ theoretical and analytic interest, which might have influenced the interpretation. The authors acknowledge that ultimate objectivity was difficult to achieve, as this is the case in most qualitative social research studies. However, this limitation was addressed through transcribing all interviews and using respondents’ direct quotes to support the research findings. The authors also recognise that the qualitative data could have generated different data patterns that could be used for inspiration for conducting further future research.
6.3 Future research
This research focusses on the PSC downstream practices, it would also be valuable to examine and investigate the PSC as a whole to understand the influences generated by other stakeholders’ actions such as the pharmaceutical companies. While this research provides insights into the factors that might affect the pharmacies’ efficiency, concentrating on the whole PSC could add more information, based on which a more reliable research could be achieved. In addition, as the current study is considered qualitative, a more quantitative strategy is a possible evolution of the study. For example, analysing the issues that emerged using structural equation modeling could allow their prioritisation, based on their relative weight of importance (Singh et al., 2013). This approach will help healthcare organisations to emphasise those component parts that are responsible for the highly complex delivery system, and thus, it will facilitate the decision-making process on synthesising a solution. The theoretical perspective of this study generates also another avenue of future research, which would be to identify innovative approaches that could be implemented to enhance the performance of PSCs. Furthermore, although in this research the delivery practices applied within two diverse geographical areas were compared; future research is required on the PSC strategies that are adopted by different European countries and across European boundaries. A comparison between the PSC used in Europe and that existing in the USA or Australia is suggested as the healthcare system operating in these geographical areas is different than the European one, although perhaps similar in terms of population density and socio economics. It would be very interesting to identify differences and/or similarities between those areas and Europe. This type of research might highlight some pharmaceutical delivery best practices that could be transferred. In addition to this, future studies could improve the generalisability of the research findings if they are conducted in other sectors such as the food industry. Food products are considered to have similar characteristics to pharmaceuticals, considering their short expiration date and their impact on society.
