This study aims to evaluate the interface of the mobile Centralized Doctor Appointment System (CDAS), the largest mobile e-government health application developed in Turkey to allow citizens to make medical appointments at public hospitals.

A total of 40 information systems engineers took part in the study. The evaluation process was mainly based on Nielsen’s heuristics. The data obtained in the evaluation process were enriched using system usability scale to conduct a more detailed analysis.

Based on the findings, problems related to the usability of the evaluated mobile health application were identified. The most violated heuristic items were found to be “error prevention” and “user control and freedom”, whereas the least violated heuristic item was “consistency and standards”. The participants generally categorized the usability problems they identified as “minor” or “major” according to their severity.

As a developing country, Turkey has made considerable investment in mobile e-government applications in recent years. It is equally important that mobile e-government services provided by public institutions have features that make these applications effective, efficient and satisfying for citizens. Therefore, the usability of mobile health applications in government services needs to be researched to improve their effectiveness and guide authorities, practitioners and designers.

Despite the enormous potential of mobile health (mHealth), identifying the asymmetric relationship among the predictors towards intention to use (ITU) of mHealth tends to remain unresolved. This study aims to investigate the predictors and their asymmetric effects on ITU of mHealth through patients and healthcare professionals.

An integrated information systems (IS) model with four additional constructs has been developed to analyze symmetric and asymmetric effects on ITU of mHealth. An exploratory survey on 452 mHealth users with prior experience was conducted to evaluate the model using a mixed-method approach including partial least squares-based structural equation modeling (PLS-SEM) and fuzzy-set qualitative comparative analysis (fsQCA) technique.

The findings show that facilitating conditions, personal awareness building, perceived enjoyment, effort expectancy and perceived usefulness have predictive power for ITU of mHealth. In contrast, fsQCA reveals four more alternative solutions, including the main drivers explored by PLS-SEM. The results indicate that various conditions that were not crucial in PLS-SEM analysis are shown to be sufficient conditions in fsQCA.

This study contributes to theory by integrating self-actualization factors (i.e. personal awareness building, patients as decision support unit) into the IS model. And practically, this study makes an essential contribution to users' ITU of mHealth, enabling relevant stakeholders to build strategies to implement mHealth successfully.

While mHealth has revolutionized healthcare and the prior literature only showed linear relationships, this empirical study revealed asymmetrical relationships among the determinants of ITU of mHealth. Thus, this study extends to the growing body of literature on the use of mHealth technology in the least developing nation.

Development of each domain of knowledge depends on aggregation of knowledge and documentation of available research. This paper aims to review the articles in the field of innovation ecosystem (IE), do a bibliographic analysis of the information available about each document, explain the process of developing the concept of IE in research during the past years and introduce the forerunner countries, major, top journals, main scientific documents and authors contributing so far to the development of the concept of IE.

In this study, 1,233 papers published between 1990 and 2021 April were collected and analyzed by applying life-cycle analysis, bibliometrics and content analysis to provide a full thematic overview of the IE filed.

Results showed that initial concepts of IE emerged in 1990 and entered its life-cycle growth period in 2006 due to being accepted by researchers. This growth will continue until 2035. Moreover, top 20 countries (i.e. the most influential and productive countries), most frequently cited journals, top publishing authors and the most important topics as considered by researchers are also identified by employing bibliometrics and content analysis. According coincidence of key words, the most important topics in IE field categorized into four groups.

Unlike other works recruiting content analysis solely to identify theoretical areas within this concept, the present study used content analysis in the field of scientific research methodology, and then the most popular tools to develop the concept of IE were identified.

The purpose of this study was to examine how cost, network and technology factors affect the use of mobile technologies for clients’ care in internal medicine department in Nigeria’s premier teaching hospital, the University College Hospital, Ibadan.

The study adopted a survey design covering a cross-section of medical doctors, pharmacists, nurses and medical laboratory technologists in the Department of Internal Medicine. A questionnaire guided data collection.

There is a high level of consciousness and use of mobile technologies for meeting healthcare needs of internal medicine clients in the University College Hospital, Ibadan and medical practitioners are deploying the technology most. However, there is no similar evidence of consciousness and use of wearable health-care technologies and solutions. The hospital makes some provision for mobile technology support for relevant medical staff and purposes. However, about three in 10 of the respondents reported that they use their own funds to recharge hospital-provided mobile phones means.

The study focusses only on one institution but the result reflects the situation in other hospitals, University College Hospital, Ibadan, Nigeria being the major supplier of health and medical human resources in the country.

The hospital requires undertaking institutional assessment of mobile service need and consumption for clients’ care and thereafter make adequate provision to match the need. Furthermore, the institution could work out various forms of collaboration with mobile technology operators in the country to subsidise the cost of the use of telephones for clients’ care as part of their corporate social responsibility.

The institution could work out collaboration with mobile technology operators in the country to subsidise cost of mobile client care as part of the philanthropic and corporate social responsibility of telecom companies.

This study focusses mainly on internal medicine and has implication for a more proper understanding of adult deployment of mobile phones for client care.

The study has two aims: first, it aimed to investigate the impact of contextual factors (such as information quality, service quality, system quality, trust in applications (app) and COVID-19 health anxiety) on the intention to use the Mobile Payment (MP) app, and subsequently, the actual use of the app. Second, the aim of this study is whether the COVID-19 threat has a moderating influence on the relationship between customers' intent to use MP app and the actual use of MP app.

The data are collected through an online survey from 341 Mobile Banking (MB) app users from Pakistan to empirically analyze the relationship between service quality, system quality, information quality, trust in the app, COVID-19 health anxiety and COVID-19 threat, intentions to use MB-app and actual use of MB-app.

The empirical analysis of the data collected from MB-app users from Pakistan shows that service quality, system quality, information quality, trust in the app and COVID-19 health anxiety positively related to intentions to use MB-app, consequently affect the actual use of MB-app. Furthermore, the results demonstrate that the COVID-19 threat positively moderates the relationship between intentions to use MB-app and actual use of MB-app.

Although, prior research established a positive impact of mobile apps on customer service and consumer satisfaction. Yet, it is not clear which factors influence customers to adopt MB-app. This study contributes to the research on MB-apps based on adaptive structuration theory and examines the technological factors and contextual factors that collectively explain when and how individuals decide to adopt MB-app.

This paper aims to present a longitudinal and visualising study using bibliometric approaches to depict the emerging trends and research hotspots within the mobile information system domain.

Publications included in the Web of Science (WoS) database for 2001–2021 are reviewed and analysed on various aspects through coauthorship, cocitation and co-occurrence analysis. The analyses are conducted using VOSViewer, a scientific visualisation software program.

Academic publications related to mobile information systems fluctuated at a low level during the initial part of the 21st century and have grown rapidly in number in the past decade. The USA and China are the leading contributors to these publications and hold dominant positions in the obtained collaboration network. Computer science, engineering and telecommunications are the top three research areas in which mainstream mobile information system research occurs. Moreover, medical informatics and health-care science services have gradually become new research hotspots.

This study provides a systematic and holistic account of the developmental landscape of the mobile information system domain. This study provides a good basis for analysing the evolution of research in mobile information systems and may serve as a potential foundation for future research.
