Failure to rescue events, or events involving preventable deaths from complications, are a significant contributor to inpatient mortality. While many interventions have been designed and implemented over several decades, this patient safety issue remains at the forefront of concern for most hospitals. In the first part of this study, the development and implementation of one type of highly studied and widely adopted rescue intervention, algorithm-based patient assessment tools, is examined. The analysis summarizes how a lack of systems-oriented approaches in the design and implementation of these tools has resulted in suboptimal understanding of patient risk of mortality and complications and the early recognition of patient deterioration. The gaps identified impact several critical aspects of excellent patient care, including information-sharing across care settings, support for the development of shared mental models within care teams, and access to timely and accurate patient information.

This chapter describes the use of several system-oriented design and implementation activities to establish design objectives, model clinical processes and workflows, and create an extensible information system model to maximize the benefits of patient state and risk assessment tools in the inpatient setting. A prototype based on the product of the design activities is discussed along with system-level considerations for implementation. This study also demonstrates the effectiveness and impact of applying systems design principles and practices to real-world clinical applications.

Although it is widely acknowledged that health care delivery systems are complex adaptive systems, there are gaps in understanding the application of systems engineering approaches to systems analysis and redesign in the health care domain. Commonly employed methods, such as statistical analysis of risk factors and outcomes, are simply not adequate to robustly characterize all system requirements and facilitate reliable design of complex care delivery systems. This is especially apparent in institutional-level systems, such as patient safety programs that must mitigate the risk of infections and other complications that can occur in virtually any setting providing direct and indirect patient care. The case example presented here illustrates the application of various system engineering methods to identify requirements and intervention candidates for a critical patient safety problem known as failure to rescue. Detailed descriptions of the analysis methods and their application are presented along with specific analysis artifacts related to the failure to rescue case study. Given the prevalence of complex systems in health care, this practical and effective approach provides an important example of how systems engineering methods can effectively address the shortcomings in current health care analysis and design, where complex systems are increasingly prevalent.

The purpose of this paper is to assess whether clinicians have an accurate perception of the preventability of their patients’ mortality. Case note review estimates that approximately 5 percent of inpatient deaths are preventable.

The design involved in the study is a prospective audit of inpatient mortality in a single NHS hospital trust. The case study includes 979 inpatient mortalities. A number of outcome measures were recorded, including a Likert scale of the preventability of death- and NCEPOD-based grading of care quality.

Clinicians assessed only 1.4 percent of deaths as likely to be preventable. This is significantly lower than previously published values (p<0.0001). Clinicians were also more likely to rate the quality of care as “good,” and less likely to identify areas of substandard clinical or organizational management.

The implications of objective assessment of the preventability of mortality are essential to drive quality improvement in this area.

There is a wide disparity between independent case note review and clinicians assessing the care of their own patients. This may be due to a “knowledge gap” between reviewers and treating clinicians, or an “objectivity gap” meaning clinicians may not recognize preventability of death of patients under their care.

This study gives some insight into deficiencies in clinical governance processes.

No similar study has been performed. This has significant implications for the idea of the preventability of mortality.

Warren Buffett asserted that the greatest issue confronting American business and the economy is rising health-care costs, which have risen to 17% of gross domestic product. Public policymakers, health-care providers and other stakeholders grapple with cost-containment and increased health-care delivery efficiencies. There exists a paucity of theory-driven research addressing how information technology vis-à-vis electronic health records (EHR) may supply a managerial mechanism for increasing bottom-line hospital performance, thereby attaining competitive advantage.

A systematic interdisciplinary literature review motivated by resource advantage theory (RAT) offers a conceptual foundation for analyzing the financial, informational and physical workflows that are core elements of supply chain management in a hospital.

RAT links how EHR impacts profitability, competitive advantage and macromarketing factors in hospital supply chains. The literature review provides a research synthesis of the implementation and adoption of EHR to reveal its impact on a hospital’s competitive advantage. Although legislative initiatives like the 2009 Health Information Technology for Economic and Clinical Health Act and the Affordable Care Act encourage EHR adoption, there remains a reluctance for hospitals to do so.

The extant literature precedes the relevant legislation, has incomplete data or focuses solely on patient outcomes.

Public reports of provider-specific patient outcomes aim to help consumers select suppliers of medical services. Yet, in an environment of rapidly changing medical technology and increasingly heterogeneous patient populations, and because they necessarily reflect the experience of other patients who received care in the past, such reports may be of limited value in helping patients forecast the probability of an adverse outcome for each provider they are considering. I propose that providers underwrite insurance policies that promptly pay patients a predetermined sum after an adverse outcome. Patients can use such outcome warranties to infer quality differences among providers easily and reliably. In addition, outcome warranties efficiently reward both providers and patients for reducing the risk of adverse outcomes and thereby improve the safety and affordability of health care. As such, outcome warranties help advance four important goals of health care management: reduction of financial risk, recruitment and retention of physicians, remediation of adverse outcomes, and raising the provider's reputation.

The purpose of this study is to investigate how two types of drivers, namely, executive compensation and market competition, can affect hospital quality in the USA. Recently, patients, insurers and regulators have increasingly focused on hospital quality. Understanding the interplay of incentives in this industry is important because in 2019, hospital treatment contributed $1.161bn to health-care costs in the USA. This study answers the call for more studies in the so-called “mixed” industry, where ownership differences can affect organizational objectives and operating constraints.

This study explores the roles of hospital executive compensation and industry competition as determinants of health-care quality. Specifically, the study probes the heterogeneity in the factors that influence quality across hospital types in the USA.

Using California hospital data from 2006 through 2020, the findings show that the effects of compensation and competition on hospital quality differ by ownership type. Executive compensation is positively associated with quality in for-profit hospitals but is not associated with that of nonprofit hospitals, suggesting for-profit hospitals are more likely to use higher levels of compensation to attract managers with higher ability, whereas the utility function for nonprofit managers may be multidimensional. Within the nonprofit hospital group, competition is more positively associated with quality for religious nonprofits relative to secular nonprofits, suggesting that competition provides more monitoring for religious hospitals.

Taken together, the findings provide evidence that the drivers of quality vary across hospitals in ways consistent with differences in constraints and objectives across ownership types. The findings are important for regulators seeking to incentivize higher quality. For example, Medicare in the USA has incorporated quality measures into its new hospital reimbursement scheme (value-based purchasing) to incentivize quality. This study proposes that regulators should consider differences across ownership types when evaluating the best ways to incentivize hospital quality.

Context. The most advanced and fastest growing form of bariatric surgery is laparoscopic gastric bypass. Very little is known about population-based 180-day laparoscopic bypass costs, complication rates, readmission rates, and post-operative care.

Objective. To examine the 6-month costs and outcomes of laparoscopic vs. open bariatric bypass surgery using a national population-based sample.

Design. We use the 1998–2003 Nationwide Inpatient Sample to examine national trends in the rate of laparoscopic bypass. To examine post-operative outcomes, we examine insurance claims for 2,384 bariatric bypass surgeries, at 308 hospitals, among a population of 5.6 million non-elderly people covered by large employers across 49 states in 2001 and 2002. Multivariate logit regression analysis is performed to risk-adjust outcomes.

Main Outcome Measures. 180-day outcomes: 12 complications specific to bariatric surgery and 44 general post-operative conditions, readmission rates, ER rates, and expenditures following bariatric surgery.

Results. Between 1998 and 2003, the national percentage of bariatric bypass surgeries that were laparoscopic grew from 1.5 to 17.1%. There was no significant difference in in-hospital mortality between laparoscopy and open surgery. With the 2001–2002 claims data, we find that of the patients having bypass surgery, men had 48% lower odds of having laparoscopy and that high bariatric volume hospitals were close to four times more likely to use laparoscopy. Laparoscopic bypass, compared with open bypass, had 34% lower odds of a complication during the initial surgical stay, 27% lower odds of a 30-day complication, but no statistically significant difference in 180-day complications. Laparoscopy had 49% higher odds of having the general 44 post-operative conditions, with 45% higher odds of a readmission and 54% higher odds of an ER visit. However, overall, laparoscopy resulted in a 23% lower number of hospital days and 9% lower 180-day expenditures.

Conclusion. The laparoscopic cost-savings during the less invasive initial surgery stay outweigh the increase in post-discharge utilization. Further cost-savings will only emerge from laparoscopy only if its late post-operative complications are reduced. More cost-savings will also emerge as more physicians switch to the use of laparoscopy for bypass surgery.

The purpose of this paper is to determine associations between initially recorded deviations in individual bedside vital parameters that contribute to total Modified Early Warning Score (MEWS) levels 2 or 3 and further clinical deterioration (MEWS level=4).

This was a prospective study in which 27,504 vital parameter values, corresponding to a total MEWS level⩾2, belonging to 1,315 adult medical and surgical inpatient patients admitted to a 90-bed study setting at a university hospital, were subjected to binary logistic and COX regression analyses to determine associations between vital parameter values initially corresponding to total MEWS levels 2 or 3 and later deterioration to total MEWS level ⩾4, and to evaluate corresponding time intervals.

Respiratory rate, heart rate and patient age were significantly (p=0.012, p<0.001 and p=0.028, respectively) associated with further deterioration from a total MEWS level 2, and the heart rate also (p=0.009) from a total MEWS level 3. Within 24 h from the initially recorded total MEWS levels 2 or 3, 8 and 17 percent of patients, respectively, deteriorated to a total MEWS level=4. Patients initially scoring MEWS 2 had a 27 percent 30-day mortality rate if they later scored MEWS level=4, and 8.7 percent if they did not.

It is important to observe all patients closely, but especially elderly patients, if total MEWS levels 2 or 3 are tachypnoea and/or tachycardia related.

Findings might contribute to patient safety by facilitating appropriate clinical and organizational decisions on adequate time spans for early warning scoring in general ward patients.

The purpose of this paper is to identify and describe hospital quality indicators, classifying them according to Donabedian’s structure, process and outcome model and in specific domains (quality, safety, infection and mortality) in two care divisions: inpatient and emergency services.

A systematic review identified hospital clinical indicators. Two independent investigators evaluated 70 articles/documents located in electronic databases and nine documents from the grey literature, 35 were included in the systematic review.

In total, 248 hospital-based indicators were classified as infection, safety, quality and mortality domains. Only 10.2 percent were identified in more than one article/document and 47 percent showed how they were calculated/obtained. Although there are scientific papers on developing, validating and hospital indicator assessment, most indicators were obtained from technical reports, government publications or health professional associations.

This review identified several hospital structure, process and outcome quality indicators, which are used by different national and international groups in both research and clinical practice. Comparing performance between healthcare organizations was difficult. Common clinical care standard indicators used by different networks, programs and institutions are essential to hospital quality benchmarking.

To the authors’ knowledge, this is the first systematic review to identify and describe hospital quality indicators after a comprehensive search in MEDLINE/PubMed, etc., and the grey literature, aiming to identify as many indicators as possible. Few studies evaluate the indicators, and most are found only in the grey literature, and have been published mostly by government agencies. Documents published in scientific journals usually refer to a specific indicator or to constructing an indicator. However, indicators most commonly found are not supported by reliability or validity studies.

Tertiary hospitals have registered an incremental rise in expenditure mostly because of the increasing demands by ageing populations. Reducing the length of stay (LOS) of patients within tertiary hospitals is one of the strategies, which has been used in the last decades to ensure health care systems’ sustainability. Furthermore, LOS is one of the key performance indicators, which is widely used to assess hospital efficiency. Hence, it is crucial that policy makers use evidence-based practices in health care to aim for optimal LOS. The purpose of this paper is to identify and summarize empirical research that brings together studies on the various variables that directly or indirectly impact on LOS within tertiary hospitals so as to develop a LOS causal systems model.

This scoping review was guided by the following research question: “What is affecting the LOS of patients within tertiary-level health care?” and by the guidelines specified by Arksey and O’Malley (2005), and by Armstrong et al. (2011). Relevant current literature was retrieved by searching various electronic databases. The PRISMA model provided the process guidelines to identify and select eligible studies.

An extensive literature search yielded a total of 30,350 references of which 46 were included in the final analysis. These articles yielded variables, which directly/indirectly are linked to LOS. These were then organized according to the Donabedian model – structure, processes and outcomes. The resultant LOS causal model reflects its complexity and confirms the consideration by scholars in the field that hospitals are complex adaptive systems, and that hospital managers must respond to LOS challenges holistically.

This paper illustrates a complex LOS causal model that emerged from the scoping review and may be of value for future research. It also highlighted the complexity of the construct under study.
