Perceived usefulness and perceived ease of use of electronic health records among nurses: Application of Technology Acceptance Model

The influence of knowledge and perceptions of doctors on the quality of medical records

Background: Medical record reflects the quality of health services provided, which is influenced by existing resources, such as the doctors in charge. This study aims to determine whether doctors’ knowledge and perceptions affect the quality of the medical record.

Design and Methods: This is a quantitative and cross-sectional study carried out at Dr. Soetomo’s general and academic hospital Surabaya, Indonesia, in September and October 2020. Data were purposively obtained from a total of 45 doctors working at the hospital’s inpatient service surgery ward using the questionnaire and checklist medical record quality. Furthermore, ethical clearance and doctors’ informed consent were obtained, with the data statistically processed and analyzed by multiple linear regressions.

Results: The results and conclusion showed that doctors’ knowledge and perceptions of the quality of medical records were influence to medical record quality (p<0.05).

Conclusions: Hospital management needs to regularly increase doctors’ knowledge and perceptions by socializing and monitoring medical records.

Usability evaluation of a nursing information system by applying cognitive walkthrough method

BACKGROUND AND OBJECTIVE

The user interface usability of the nursing information system (NIS) should be such that the nurses can learn and interact with it easily and quickly. Therefore, it is necessary to identify and solve the usability problems of these systems. The present study aimed to evaluate the usability of a NIS using the cognitive walkthrough (CW) evaluation method.

METHODS

Based on five selected scenarios, five evaluators evaluated the NIS in Shafa Hospital Information System. After identifying the problems, the evaluators assigned each problem to one of the usability attributes. The severity of each identified problem was determined by the evaluators and five real users of the system.

RESULTS

In total, 24 unique problems were identified. The average severity of the problems was determined by the evaluators (2.77) and the actual users (2.82) in the "major problem" category. The highest number of problems were assigned to the scenarios 3 and 2 with 15 and 14 problems, respectively. The highest average severity in terms of evaluations and actual users was related to the scenario 5 (3.06 and 2.94, respectively), which was in the "major problem" category. The highest number of problems were associated with learnability (8 problems) and efficiency (6 problems).

CONCLUSION

Since most of the nurses do not have enough time for learning the system, and given that the selected scenarios for evaluation were based on the most frequent daily tasks that nurses performed using the NIS; The correction of usability problems in the scenarios 3 and 2 that had the highest number of problems and the scenario 5 that had the highest average severity and execution time; it can reduce the nurses' cognitive load and the learning time of the system and increase the efficiency of nurses.

Factors Affecting General Practitioners' Readiness to Accept and Use an Electronic Health Record System in the Republic of North Macedonia: A National Survey of General Practitioners

Background

Electronic health records (EHRs) represent an important aspect of digital health care, and to promote their use further, we need to better understand the drivers of their acceptance among health care professionals. EHRs are not simple computer applications; they should be considered as a highly integrated set of systems. Technology acceptance theories can be used to better understand users’ intentions to use EHRs. It is recommended to assess factors that determine the future acceptance of a system before it is implemented.

Objective

This study uses a modified version of the Unified Theory of Acceptance and Use of Technology with the aim of examining the factors associated with intentions to use an EHR application among general practitioners (GPs) in the Republic of North Macedonia, a country that has been underrepresented in extant literature. More specifically, this study aims to assess the role of technology acceptance predictors such as performance expectancy, effort expectancy, social influence, facilitating conditions, job relevance, descriptive norms, and satisfaction with existing eHealth systems already implemented in the country.

Methods

A web-based invitation was sent to 1174 GPs, of whom 458 completed the questionnaire (response rate=40.2%). The research instrument assessed performance expectancy, effort expectancy, facilitating conditions, and social influence in relation to the GPs’ intentions to use future EHR systems. Job relevance, descriptive norms, satisfaction with currently used eHealth systems in the country, and computer/internet use were also measured.

Results

Hierarchical linear regression analysis showed that effort expectancy, descriptive norms, social influence, facilitating conditions, and job relevance were significantly associated with intentions to use the future EHR system, but performance expectance was not. Multiple mediation modeling analyses further showed that social influence (z=2.64; P<.001), facilitating conditions (z=4.54; P<.001), descriptive norms (z=4.91; P<.001), and effort expectancy (z=5.81; P=.008) mediated the association between job relevance and intentions. Finally, moderated regression analysis showed that the association between social influence and usage intention was significantly moderated (P=.02) by experience (B_{experience×social influence}=.005; 95% CI 0.001 to 0.010; β=.080). In addition, the association between social influence and intentions was significantly moderated (P=.02) by age (B_{age×social influence}=.005; 95% CI 0.001 to 0.010; β=.077).

Conclusions

Expectations of less effort in using EHRs and perceptions on supportive infrastructures for enabling EHR use were significantly associated with the greater acceptance of EHRs among GPs. Social norms were also associated with intentions, even more so among older GPs and those with less work experience. The theoretical and practical implications of these findings are also discussed.

Physicians' gender and their use of electronic health records: findings from a mixed-methods usability study

OBJECTIVE

Physician burnout associated with EHRs is a major concern in health care. A comprehensive assessment of differences among physicians in the areas of EHR performance, efficiency, and satisfaction has not been conducted. The study sought to study relationships among physicians' performance, efficiency, perceived workload, satisfaction, and usability in using the electronic health record (EHR) with comparisons by age, gender, professional role, and years of experience with the EHR.

MATERIALS AND METHODS

Mixed-methods assessments of the medical intensivists' EHR use and perceptions. Using simulated cases, we employed standardized scales, performance measures, and extensive interviews. NASA Task Load Index (TLX), System Usability Scale (SUS), and Questionnaire on User Interface Satisfaction surveys were deployed.

RESULTS

The study enrolled 25 intensive care unit (ICU) physicians (11 residents, 9 fellows, 5 attendings); 12 (48%) were men, with a mean age of 33 (range, 28-55) years and a mean of 4 (interquartile range, 2.0-5.5) years of Epic experience. Overall task performance scores were similar for men (90% ± 9.3%) and women (92% ± 4.4%), with no statistically significant differences (P = .374). However, female physicians demonstrated higher efficiency in completion time (difference = 7.1 minutes; P = .207) and mouse clicks (difference = 54; P = .13). Overall, men reported significantly higher perceived EHR workload stress compared with women (difference = 17.5; P < .001). Men reported significantly higher levels of frustration with the EHR compared with women (difference = 33.15; P < .001). Women reported significantly higher satisfaction with the ease of use of the EHR interface than men (difference = 0.66; P =.03). The women's perceived overall usability of the EHR is marginally higher than that of the men (difference = 10.31; P =.06).

CONCLUSIONS

Among ICU physicians, we measured significant gender-based differences in perceived EHR workload stress, satisfaction, and usability-corresponding to objective patterns in EHR efficiency. Understanding the reasons for these differences may help reduce burnout and guide improvements to physician performance, efficiency, and satisfaction with EHR use.

DESIGN

Mixed-methods assessments of the medical intensivists' EHR use and perceptions. Using simulated cases, we employed standardized scales, performance measures, and extensive interviews.

Perceptions of healthcare professionals about the adoption and use of EHR in Gulf Cooperation Council countries: a systematic review

Introduction

Electronic health records (EHRs) can improve the quality and safety of care. However, the adoption and use of the EHR is influenced by several factors, including users’ perception.

Objectives

To undertake a systematic review of the literature to understand healthcare professionals’ perceptions about the adoption and use of EHRs in Gulf Cooperation Council (GCC) countries in order to influence the implementation strategies, training programme and policy development in the GCC region.

Method

A systematic literature search was undertaken on seven online databases to identify articles published between January 2006 and December 2017 examining healthcare professionals’ perception towards the adoption and use of EHR in the Gulf context.

Results

The fourteen articles included in this review identified both positive and negative perceptions of the role of EHR in healthcare. The positive perceptions included EHR benefits, such as improvements to work efficiency, quality of care, communication and access to patient data. Conversely, the negative perceptions were associated with challenges or risks of adopting an EHR, such as disruption of provider–patient communication, privacy and security concerns and high initial costs. The perceptions were influenced by personal factors (eg, age, occupation and computer literacy) and system factors (perceived usefulness and perceived ease of use).

Conclusion

Positive perceptions of EHRs by the healthcare professionals could facilitate the adoption of this technology in the Gulf region, particularly when barriers are addressed early. Negative perceptions may inform change management strategies during adoption and implementation. The perceptions should be further evaluated from a technology acceptance perspective.

The Applicability of the Modified Technology Acceptance Model (TAM) on the Sustainable Adoption of eHealth Systems in Resource-Limited Settings

BACKGROUND

The implementation of eHealth systems with a trial-and-error approach is very expensive and unsuccessful. So, this study aims to examine the constructs and relationships of the modified technology acceptance model (TAM) to determine whether it can be applied to assess health professional's behavioral intention to adopt eHealth systems in resource-limited settings or not.

METHODS

The institutional-based cross-sectional study design was conducted among a total of 384 healthcare professionals in referral hospitals of Amhara regional state, Ethiopia. Self-administered questionnaire was used to collect the data, and the data were entered using Epi-info version 7 and the descriptive data were analyzed using SPSS version 25. Structural equation modeling, using AMOS 22, was also applied to describe and validate the degree of relationships between variables.

RESULTS

The findings of the structural equation modeling (SEM) indicate that perceived usefulness has a significant influence on attitude (β =0.298, P<0.01) and intention to use eHealth (β =0.387, P<0.01). Perceived ease of use has significant influence on perceived usefulness (β=0.385, P<0.05) and attitude (β=0.347, P<0.05) and intention to use eHealth (β=0.339, P<0.01). Technical infrastructure has significant influence on attitude (β =0.412, P<0.01) and intention to use eHealth (β =0.355, P<0.01). The staffs IT experience has a significant influence on perceived usefulness (β =0.595, P<0.01) and attitude (β =0.267, P<0.05), but the effect of IT experience on the intention to use eHealth was not significant. Among all the constructs, healthcare professionals attitude towards eHealth showed the strongest effect on the intention to use eHealth systems (β = 0.52, P<0.01).

CONCLUSION

Overall, this model describes 56.2% of the variance in behavioral intention to use eHealth systems. Therefore, the implementers should give priority in enhancing the organizations technical infrastructure, staff's IT skill, and their attitude towards eHealth by giving continuous support.

Factors Influencing Healthcare Professionals' Perception towards EHR/EMR Systems in Gulf Cooperation Council Countries: A Systematic Review

Electronic health and medical records are widely adopted in many healthcare settings worldwide to improve the quality of care. Users’ perception is a significant factor influencing the successful implementation and use of e-health technologies. This systematic review aimed to identify factors influencing the perceptions of healthcare professionals towards the adoption and use of electronic health and medical record systems to improve the quality of healthcare services in the countries of the Gulf Cooperation Council. We identified primary studies evaluating healthcare professionals’ perception towards electronic health records and/or electronic medical records in the Gulf region. Seven electronic databases, including Medline, CINAHL, Informit Health Collection, Science Direct, ProQuest, PubMed, and Scopus were used to search for the relevant articles published between January 2007 and December 2016. Thirteen articles met the inclusion criteria and were included in this systematic review. Both individual and system-related factors were found to positively or negatively influence healthcare providers’ perceptions towards the systems. Understanding the impact of healthcare professionals’ perception of health information technology is important for policymakers involved in the implementation programs to ensure their success. Future studies should evaluate other individual characteristics such as age, gender, and profession of the healthcare providers on their perceptions towards e-health technologies.

Intention to use electronic medical record and its predictors among health care providers at referral hospitals, north-West Ethiopia, 2019: using unified theory of acceptance and use technology 2(UTAUT2) model

BACKGROUND

Electronic Medical Records (EMRs) are systems to store patient information like medical histories, test results, and medications electronically. It helps to give quality service by improving data handling and communication in healthcare setting. EMR implementation in developing countries is increasing exponentially. But, only few of them are successfully implemented. Intention to use EMRs by health care provider is crucial for successful implementation and adoption of EMRs. However, intention of health care providers to use EMR in Ethiopia is unknown.

OBJECTIVE

The aim of this study was to assess health care provider's intention to use and its predictors towards Electronic Medical Record systems at three referral hospitals in north-west, Ethiopia, 2019.

METHODS

Institutional based cross-sectional explanatory study design was conducted from March to September among 420 health care providers working at three referral hospitals in north-west Ethiopia. Data were analyzed using structural equation model (SEM). Simple and multiple SEM were used to assess the determinants of health care providers intention to use EMRs. Critical ratio and standardized coefficients were used to measure the association of dependent and independent variables, 95% confidence intervals and P-value were calculated to evaluate statistical significance. Qualitative data was analyzed using thematic analysis.

RESULT

The mean age of the study subjects was 32.4 years ±8.3 SD. More than two-third 293(69.8%) of the participants were male. Among 420 health care providers, only 167 (39.8%) were scored above the mean of intention to use EMRs. Factors positively associated with intention to use EMRs were performance expectancy (β = 0.39, p < 0.001), effort expectancy (β = 0.24,p < 0.001),social influence (β = 0.18,p < 0.001),facilitating condition (β = 0.23,p < 0.001), and computer literacy (β = 0.08,p < 0.001). Performance expectancy was highly associated with intention to use EMRs.

CONCLUSION

Generally, about 40 % of health care providers were scored above the mean of intention to use EMRs. Performance expectancy played a major role in determining health care providers' intention to use EMRs. The intention of health care providers to use EMRs was attributed by social influence, facilitating condition in the organization, effort expectancy, performance expectancy and computer literacy. Therefore, identifying necessary prerequisites before the actual implementation of EMRs will help to improve the implementation status.

Perspectives of Nursing Homes Staff on the Nature of Residents-Initiated Call Lights

Little research has been conducted to capture the perceptions of nursing home staff when using the call light system. There is also a lack of information regarding the effects that these perceptions of the call light system have on their workload, safety, quality of care, or overall satisfaction. In response to the high volume of complaints from residents and their families regarding long response times to call light alarms, we developed this exploratory cross-sectional survey study. This study aims to capture nursing home staff experiences while using a call light system; to investigate the challenges the staff face when using the system; and to determine how these challenges contribute to their workload, performance, and satisfaction. A survey instrument was developed and distributed to all 153 of the nursing staff, certified nursing assistants, and licensed practical nurses in a nursing home in upstate New York. A total of 105 completed surveys were retrieved for an overall response rate of 68.63%. Descriptive analysis, Pearson correlation, and the Kruskal-Wallis test were used to analyze the collected data. The results showed a significant correlation between the processes of being notified and locating call light alarms and workload. The staff reported many usability challenges that may contribute to longer response time such as lack of prioritization, low/no discriminability, noise, and overwrite previous alarm. In addition, 78% of the staff agreed that responding to a call light can prevent serious harm; however, 56% of the staff agreed that call light system is not meaningful; and around 78% think that call light system is disruptive in the environment and source for constant noise. The study finds that incorporating the insights provided by nursing home staff may improve the acceptance of new and existing technology, which ultimately improves the delivery of care through greater usability.

Acceptance of Online Medical Websites: An Empirical Study in China

As a new type of public health service product, online medical websites (OMWs) are becoming quite popular. OMWs can address patients' basic medical problems remotely and give health guidance online. Compared to traditional hospitals, OMWs are more convenient and inexpensive, they can usually provide a better service for patients with poor medical conditions (especially in rural areas), and they also contribute to the rational distribution of medical resources. Therefore, key factors that affect patients' acceptance of OMWs must be identified to contribute to public health. By integrating perceived risk (PR) and the technology acceptance model (TAM), we proposed a modified TAM and clarified how PR and other factors affect patients' behavioral intention (BI) towards OMWs. A sample of 245 research participants in China took part in this study and the structural equation model (SEM) was used to test our hypotheses. The results revealed that perceived usefulness (PU) is a positive predictor of BI but has no significant effect on attitude (ATT), while perceived ease of use (PEOU) can affect BI through PU and attitude (ATT). Moreover, trust (TRU) was identified as a mediator of PR and PU/PEOU. Also, the doctor⁻patient relationship (DPR) was shown to moderate PR and TRU. In order to increase patients' BI, OMW providers need further innovations to improve patients' TRU and reduce their PR.

Comprehensive user requirements engineering methodology for secure and interoperable health data exchange

Background

Increased digitalization of healthcare comes along with the cost of cybercrime proliferation. This results to patients’ and healthcare providers' skepticism to adopt Health Information Technologies (HIT). In Europe, this shortcoming hampers efficient cross-border health data exchange, which requires a holistic, secure and interoperable framework. This study aimed to provide the foundations for designing a secure and interoperable toolkit for cross-border health data exchange within the European Union (EU), conducted in the scope of the KONFIDO project. Particularly, we present our user requirements engineering methodology and the obtained results, driving the technical design of the KONFIDO toolkit.

Methods

Our methodology relied on four pillars: (a) a gap analysis study, reviewing a range of relevant projects/initiatives, technologies as well as cybersecurity strategies for HIT interoperability and cybersecurity; (b) the definition of user scenarios with major focus on cross-border health data exchange in the three pilot countries of the project; (c) a user requirements elicitation phase containing a threat analysis of the business processes entailed in the user scenarios, and (d) surveying and discussing with key stakeholders, aiming to validate the obtained outcomes and identify barriers and facilitators for HIT adoption linked with cybersecurity and interoperability.

Results

According to the gap analysis outcomes, full adherence with information security standards is currently not universally met. Sustainability plans shall be defined for adapting existing/evolving frameworks to the state-of-the-art. Overall, lack of integration in a holistic security approach was clearly identified. For each user scenario, we concluded with a comprehensive workflow, highlighting challenges and open issues for their application in our pilot sites. The threat analysis resulted in a set of 30 user goals in total, documented in detail. Finally, indicative barriers of HIT acceptance include lack of awareness regarding HIT risks and legislations, lack of a security-oriented culture and management commitment, as well as usability constraints, while important facilitators concern the adoption of standards and current efforts for a common EU legislation framework.

Conclusions

Our study provides important insights to address secure and interoperable health data exchange, while our methodological framework constitutes a paradigm for investigating diverse cybersecurity-related risks in the health sector.
