health information systems
Atalag K et al, electronic Journal of Health Informatics, 7(1)
Maintaining health information systems over time requires significant effort and time. This is especially marked in clinical information systems where most, if not all, functional software requirements are dependent on healthcare concepts and processes which are prone to high rate of change. Software engineering literature indicates that maintenance tasks alone may constitute 70-80% of the total development cost. It has been suggested that openEHR based systems will effectively tackle this by separating domain knowledge from software code. The objective of this paper is to assess the maintainability of an openEHR based clinical application with comparison to another application based on the same functional requirements but implemented using traditional development methods.

Background
Information deficits contribute to medical errors. Hence several efforts to develop electronic communication systems to facilitate a flow of information between health care providers have been attempted, including initiatives to develop regional or national electronic patient summaries.
Objectives
To study information access and information needs in inpatient emergency departments, and how clinicians in these departments handle deficits in available information.

Reports of health information systems failures identified the guilty parties laying with issues around social, technical, and organizational factors. The reason so many systems fail may lie in the socio-cultural fit of e-Health systems. We do not understand how to deliver information to providers when they need it, in a usable format, and in a way that fits transparently into their workflow and into the daily lives of patients.

Tele-intensive care unit (ICU) is a care provided to critically ill patients by off-site clinicians using audio, video, and electronic links to leverage technical, informational, and clinical resources. Providing care includes the ability to detect patient’s instability or laboratory abnormalities in real-time, collect additional clinical information from or about the patient, order diagnostic testing, make diagnoses, implement treatment, render other forms of intensive care such as managing life-support devices, and communicate with patients and bedside providers.

Recognition of the improvements in patient safety, quality of patient care, and efficiency that health care information systems have the potential to bring has led to significant investment. Globally the sale of health care information systems now represents a multibillion dollar industry. As policy makers, health care professionals, and patients, we have a responsibility to maximize the return on this investment. To this end we analyze alternative licensing and software development models, as well as the role of standards.

With the progress and the development of information technology, the internal data in medical organizations have become computerized and are further established the medical information system. Moreover, the use of the Internet enhances the information communication as well as affects the development of the medical information system that a lot of medical information is transmitted with the Internet. Since there is a network within another network, when all networks are connected together, they will form the “Internet”. For this reason, the Internet is considered as a high-risk and public environment which is easily destroyed and invaded so that a relevant protection is acquired. Besides, the data in the medical network system are confidential that it is necessary to protect the personal privacy, such as electronic patient records, medical confidential information, and authorization-controlled data in the hospital.

The purpose of this review is to consolidate existing evidence from published systematic reviews on health information system (HIS) evaluation studies to inform HIS practice and research. Fifty reviews published during 1994-2008 were selected for meta-level synthesis. These reviews covered five areas: medication management, preventive care, health conditions, data quality, and care process/outcome. After reconciliation for duplicates, 1276 HIS studies were arrived at as the non-overlapping corpus. On the basis of a subset of 287 controlled HIS studies, there is some evidence for improved quality of care, but in varying degrees across topic areas. For instance, 31/43 (72%) controlled HIS studies had positive results using preventive care reminders, mostly through guideline adherence such as immunization and health screening. Key factors that influence HIS success included having in-house systems, developers as users, integrated decision support and benchmark practices, and addressing such contextual issues as provider knowledge and perception, incentives, and legislation/policy.

Objectives
This study aims to explore the issues and challenges involved in designing and organizing pilot implementations of health information systems (HIS). Pilot implementations are a widely used approach for identifying design flaws and implementation issues before full-scale deployment of new HIS. However, it is not uncommon for pilot implementations to fail in the sense that little can be learned from them.

We sought to understand the drivers and influencers that affect the time needed to adopt a health information management system in primary care offices. The results from three independent but interrelated studies were crystallized to understand how socio-technical factors affect the adoption of physician office systems. The duration of the adoption period is affected by differences between the culture and workflow of a clinic and the workflow design of its health information management software.

Health Information Systems (HIS) are the core support to decision-making in health organizations. Within HIS, health indicators (HI) reflect, numerically, events measured in the health-illness continuum. The integrated health information system is intended to standardize, integrate and organize all the information available in health information systems through an accessible and secure repository, and to conveniently distribute information for decision-making. To standardize information it is necessary to define standards and semantic information to enable us to identify concepts and relate them uniquely to each other.

In today’s practice of medicine, it is highly unlikely that any physician entering into or already in practice will remain in the analog age without some type of health information technology. Computers today are just as important to the psychiatric office as was the proverbial couch, and they play a central role in data collection, storage, and retrieval in various domains such as scheduling, billing, and record keeping.

With the U.S. government calling for electronic health records (EHRs) for all Americans by the year 2014, adoption of an interoperable EHR is imminent in America’s future. However, recent estimates for EHR implementation in the ambulatory care environment are just over 10 percent. This second part of a two-part study (see part one here) examines EHR acceptance factors in an academic-based healthcare system.
