They focus on the proper generation, transmission, storage, and retrieval of health data. It is obvious that production of accurate, relevant, and timely health information is foundation of good decision making. Rapid progress in wireless communications and embedded systems result in wireless sensor networks to be employed even in biomedical applications as well as their prominent deployment options. This study proposes a healthcare information system framework which consists of such components as;wireless sensor networks, cellular networks, a MATLAB interface, a database, and a web based monitoring interface. A case study that includes sensing, transferring, storing and web based monitoring processes of ECG signal is also introduced in the study, so that the behavior of the system developed can be tested. The results show that the framework presented here can not only be employed as a healthcare information system, but it can also be used as an infrastructure in related research activities and consequently, lots of time can be saved from creating an experimental environment.展开更多

However, there isstill a lack of clear understanding of the benefits of HIS at the hospital leveland the influential factors for HIS effectiveness. In this study, we propose aresearch framework to explain how HIS implementation improves hospitalperformance. Our results reinforce the positive effect of HIS on hospitalperformance. In particular, we found that HIS implementation increases boththe cost and revenue of the hospitals, but the increasing effect in revenue ismuch bigger than the increasing effect in cost. We also found that althoughboth small and big hospitals benefit from the implementation of HIS, the effectof size is different. Size has a positive effect on hospital performance for smallhospitals but has a negative effect on big hospitals. This indicates that thecompetitive advantage of economies of scale disappears for big hospitalsbecause the level of information transparency becomes lower and transactioncosts become higher as size increases.展开更多

The study employed online survey techniques. Altogether, 710 questionnaires (Google forms) were developed, and operationalized. The main respondents included 566 medical students, and 143 medical staff from Mbarara University of Science and Technology (MUST), and Kampala International University (KIU), accordingly. Using SPSS, the main statistical analysis tools employed include frequency distribution summary, and Chi-square (x<sup>2</sup>) test. According to the frequency distribution summary, 27% to 42% of the respondents within categorical divides acknowledged occurrence of medical information breaches due to SM usage. Notably, higher levels of the breaches were reported among male students (64%), age-group 18 to 35 years (68%), and WhatsApp users (63%). On the other hand, Chi-square results showed significant levels (p p > 0.05) between medical institutions and medical information breaches. Overall, the vulnerable areas of the breaches identified would serve as important reference points in the process of rationalizing SM usage in medical institutions. Nevertheless, further studies could focus on identification of the key SM usage factors associated with medical information breaches in medical institutions in Uganda.展开更多

Clinical data are generated both from the documentation of physicians' interactions with the patient and by diagnostic systems. During the care process, a number of different actors and roles (physicians, specialists, nurses, etc.) have the need to access patient data and document clinical activities in different moments and settings. Thus, data sharing and flexible aggregation based on different users' needs have become more and more important for supporting continuity of care at home, at hospitals, at outpatient clinics. In this paper, the authors identify and describe needs and challenges for patient data management at provider level and regional- (or inter-organizational-) level, because nowadays sharing patient data is needed to improve continuity and quality of care. For each level, the authors describe state-of-the-art Information and Communication Technology solutions to collect, manage, aggregate and share patient data. For each level some examples of best practices and solution scenarios being implemented in the Italian Healthcare setting are described as well.展开更多
