To reduce wasteful ordering of rare 1,25-OH vitamin D lab tests through use of a noninterruptive decision support tool.

In this systematic review, we aimed to evaluate methodological and reporting trends present in the current literature by investigating published usability studies of electronic health records (EHRs).

Implementation and adoption of complex health information technology (HIT) is gaining momentum internationally. This is underpinned by the drive to improve the safety, quality, and efficiency of care. Although most of the benefits associated with HIT will only be realized through optimization of these systems, relatively few health care organizations currently have the expertise or experience needed to undertake this. It is extremely important to have systems working before embarking [...]

The adoption of electronic health records (EHRs) across the United States has impacted the methods by which health care professionals care for their patients. It is not always recognized, however, that pharmacists also actively use advanced functionality within the EHR. As critical members of the health care team, pharmacists utilize many different features of the EHR. The literature focuses on 3 main roles: documentation, medication reconciliation, and patient evaluation and [...]

We aimed to investigate to what extent clustering of related drug interaction alerts (drug-drug and drug-disease interaction alerts) would decrease the alert rate in clinical decision support systems (CDSSs).

Thorough and ongoing testing of electronic health records (EHRs) is key to ensuring their safety and effectiveness. Many health care organizations limit testing to test environments separate from, and often different than, the production environment used by clinicians. Because EHRs are complex hardware and software systems that often interact with other hardware and software systems, no test environment can exactly mimic how the production environment will behave. An effective testing [...]

To provide a report on year 1 results of a national study investigating nursing home information technology (IT) adoption, called IT sophistication.

Event notifications are real-time, electronic, automatic alerts to providers of their patients' health care encounters at other facilities. Our objective was to examine the effects of organizational capability and related social/organizational issues upon users' perceptions of the impact of event notifications on quality, efficiency, and satisfaction.

We propose a computational framework for integrating diverse patient measurements into an aggregate health score and applying it to patient stability prediction.

The Johns Hopkins Center for Population Health IT hosted a 1-day symposium sponsored by the National Library of Medicine to help develop a national research and development (R&D) agenda for the emerging field of population health informatics (PopHI).
