Medication errors pose a serious threat in the healthcare industry. This paper aims at developing a medication error reporting system (MERS) that enables medical professionals to anonymously report medication errors by opening a case in the MERS database. The object-oriented approach was used to analyse and design the MERS system. The systems requirements are first gathered with the use of questionnaires and interviews with practitioners; then, analysed based on unified modelling language techniques such as use case, class, and sequence diagrams. Implementing a MERS into hospitals allows medical professionals to analyse error patterns by referencing archived cases in the database; thus enhancing clinical practices that prevent future errors.

Several recent works have proposed and implemented cryptography as a means to preserve privacy and security of patient's health data. Nevertheless, the weakest point of electronic health record (EHR) systems that relied on these cryptographic schemes is key management. Thus, this paper presents the development of privacy and security system for cryptography-based-EHR by taking advantage of the uniqueness of fingerprint and iris characteristic features to secure cryptographic keys in a bio-cryptography framework. The results of the system evaluation showed significant improvements in terms of time efficiency of this approach to cryptographic-based-EHR. Both the fuzzy vault and fuzzy commitment demonstrated false acceptance rate (FAR) of 0%, which reduces the likelihood of imposters gaining successful access to the keys protecting patients' protected health information. This result also justifies the feasibility of implementing fuzzy key binding scheme in real applications, especially fuzzy vault which demonstrated a better performance during key reconstruction.

The level set methods have given effective structures to medical image analysis. Nonetheless, to acquire exact limits of the objects, particularly when they have feeble edges or inhomogeneous forces, is still an extremely difficult undertaking. It is found that existing level set methodologies neglect to fragment the images with powerless edges. The hazy edges and inhomogeneous powers cause instability for segmentation. In this paper, a novel energy based level set approach is proposed in which the energy capacity is defined by contrast between the real and assessed likelihood densities of the powers and partial differential equation is determined for finding the base of the vital work. The proposed approach has been tried on medical images and find the genuine protest limits, low difference, and inhomogeneous forces. The technique determines profitable advantages like computerisation, invariance of force inhomogeneity and precise medical image portions.

In contrast to telemedicine's resurgence in the 1990s, technology is no longer perceived as a barrier to the successful deployment and utilisation of telemedicine. Yet there are reasons to believe that this perception is inaccurate. Drawing on a study of two active telemedicine networks, one of which was studied at two points in time nearly a decade apart, this research examines how technology management challenges to telemedicine have changed and how they impact its deployment and utilisation. The findings indicate that not only do previously identified technology management challenges related to lack of end-user training, and remote site technology support and infrastructure thought effectively addressed still remain, but technology management issues centring around the relationships between the telehealth centers responsible for the technology and the various clinical units involved have become more critical. The importance of the social context in which such relationships exist is highlighted.

The interplay between healthcare service quality, health IT, and variation in reimbursements for healthcare services is an understudied phenomenon. We propose a unified framework to empirically examine the association between healthcare quality, health IT usage and Medicare reimbursements for congestive heart failure cases. Hospital-level data from multiple sources, including Medicare, CMS hospital compare, and HIMSS Analytics, were obtained and integrated for the analyses reported in this study. Our empirical analyses, based on a three-year panel dataset of CHF patients, indicates a negative association between hospital mortality rates and average Medicare reimbursements, and a positive association between readmission rates and Medicare payments. We report a weak positive association between the usage of health IT systems and magnitude of average Medicare payments, suggesting that hospitals with greater usage of health IT exhibit higher Medicare reimbursements.

The design and use of technology-enabled systems are increasing in healthcare. Patients with chronic diseases use technologies to self-manage their health. To be effective, the self-management (SM) of chronic diseases must reflect the needs, lifestyles, and preferences of the patients. However, the extant literature does not make clear what patients value the most in the SM process and how these preferences are designed in the SM systems they use. In this paper, we will conduct a value-sensitive review and analysis of the literature on the technology-enabled SM of chronic diseases and conditions. We use a value-sensitive design (VSD) lens to identify what patients value in the SM process and how these values are implicated in the systems they use for SM. We provide a comprehensive list of values and explore their definitions, dimensions, and system implications. We then discuss the theoretical and practical contributions of our findings.

The implementation of electronic health records (EHR) has potential benefits to healthcare organisations. However, evidence show that EHR systems are being resisted by healthcare providers. Little research in IS has addressed this phenomenon. To understand EHR resistance, a mid-range theory is evoked from our textual analysis of responses gathered from healthcare providers at a large international hospital. The data were analysed using revealed causal mapping technique (RCM). The results revealed that EHR resistance is comprised of seven major constructs: costs, benefits, perceived value, perceived threat, organisational support, self-efficacy, and system circumvention availability. Additionally, this study also uncovered the underlying concepts that are shaping each of these constructs. This study demonstrated that the use of the RCM methodology yielded concepts and constructs of EHR resistance that are not suggested by generalised theory. The use of RCM also revealed the main interactions and linkages between these constructs.

Nowadays, hospital information systems (HISs) play a crucial role in helping medical staffs in accomplishing their daily tasks. In a hospital, actors with different profiles accomplish a variety of activities. In such a context, the processed information is variable in nature and large in quantity. The actors who may be distant, as inside, from the hospital are likely to use heterogeneous application systems. The shared data, which are exchanged in the form of records, require flexibility of access. This paper proposes a new architectural framework for an Algerian hospital system where heterogeneity of applications is involved. The proposed architecture comprises all necessary components for its well functioning.

More and more hospitals and healthcare providers are using virtual queues to better schedule patients. By participating in virtual queues, patients can avoid the prolonged and unpredictable waiting times at healthcare facilities. However, as long as there is a queue, patients will still experience frustration and fear with making the wrong decision during their waiting period. Using queuing theory, this paper provides a virtual queuing system (M/M/1 and M/M/2 models) that incorporates an added service feature that can reduce frustration, minimise fear and improve the delivery of e-healthcare. Two additional potential benefits that can accrue from this proposed virtual system are job creation and revenue generation.
