This report provides an evaluation of the National Library of Medicine-sponsored Woods Hole Medical Informatics (WHMI) course and the extent to which the objectives of the program are achieved. Two studies were conducted to examine the participants' perceptions of both the short-term (spring 2002) and the long-term influences (1993 through 2002) on knowledge, skills, and behavior. Data were collected through the use of questionnaires, semistructured telephone interviews, and participant observation [...]

As the public interest in consumer-driven electronic health care applications rises, so do concerns about the privacy and security of these applications. Achieving a balance between providing the necessary security while promoting user acceptance is a major obstacle in large-scale deployment of applications such as personal health records (PHRs). Robust and reliable forms of authentication are needed for PHRs, as the record will often contain sensitive and protected health information [...]

Community health centers serve ethnically diverse populations that may pose challenges for record linkage based on name and date of birth. The objective was to identify an optimal deterministic algorithm to link patient encounters and laboratory results for hemoglobin A1c testing and examine its variability by health center site, patient ethnicity, and other variables. Based on data elements of last name, first name, date of birth, gender, and health center [...]

Patient-centered information management may overcome barriers that impede high-quality, safe care in the emergency department (ED). The utility of parents' report of medication data via a multimedia, touch screen interface, the asthma kiosk, was investigated. Our specific aims were (1) to estimate the validity of parents' electronically entered medication history for asthma and (2) to compare the parents' kiosk entries regarding medications to the documentation of ED physicians and nurses.

Automated clinical decision support has shown promise in reducing medication errors; however, clinicians often do not comply with alerts. Because renal insufficiency is a common source of medication errors, the authors studied a trial of alerts designed to reduce inpatient administration of medications contraindicated due to renal insufficiency.

To compare the functional capabilities being offered by commercial ambulatory electronic prescribing systems with a set of expert panel recommendations.

Mapping local use names to standardized nomenclatures such as LOINC (Logical Observation Identifiers Names and Codes) is a time-consuming task when done retrospectively or during the configuration of new information systems. The author sought to identify a subset of intensive care unit (ICU) laboratory tests, which, because of their frequency of use, should be the focus of efforts to standardize test names in ICU information systems.

Petri Nets (PNs) and their extensions are promising methods for modeling and simulating biological systems. We surveyed PN formalisms and tools and compared them based on their mathematical capabilities as well as by their appropriateness to represent typical biological processes. We measured the ability of these tools to model specific features of biological systems and answer a set of biological questions that we defined. We found that different tools are [...]

Adverse events are poor health outcomes caused by medical care. Measuring them is necessary for quality improvements, but current detection methods are inadequate. We performed this study to validate a previously derived method of adverse event detection using term searching in physician-dictated discharge summaries.

This article provides information concerning a novel research subject recruitment registry developed at Vanderbilt University. Project goals were (1) to provide a mechanism for lay individuals to self-enter information conveying interest in volunteering for clinical research and (2) provide tools for researchers to select and contact potential volunteers based on study-specific inclusion criteria. The registry was built and offered as an institutional resource to all university scientists conducting institutional review [...]
