OBJECTIVE The goal of the project was to create recommendations and design specifications for a multimedia tool to enhance the informed consent process for clinical trials. The authors focused on the needs of patients with potential cognitive impairment. DESIGN The authors first performed a needs assessment using focus groups and interviews with health(More)
I evaluated the diagnostic value of routinely ordered liver-function tests in 175 biopsy-proven cases of hepatic disease by use of stepwise discriminant analysis. The tests studied-total and "direct" bilirubin, alkaline phosphatase, lactate dehydrogenase, and aspartate aminotransferase-correctly classified 45-73% of cases, depending on the homogeneity of(More)
The interpretation of clinical laboratory tests is dependent on a host of physiological, environmental and pharmacological factors. At present, it is difficult to determine which of these broad groups is involved when one suspects interference with a clinical laboratory test. Detailed knowledge of the drugs that a patient is consuming is critical in(More)
We developed of computer programs to evaluate the clinical reliability of test results by comparing each new result with previous results for the same patient, and to signal discrepancies in real time. These "delta check" discrepancies are noted, and they must be reviewed by the laboratory staff before results can appear on a patient's record. During a(More)

Future technologic advances in microcomputer hardware will allow us to build complex interactive information systems that go far beyond conventional laboratory management functions to address the needs of laboratorians as well as physicians in patient care activities. These systems will use a "local-area network to transmit not only text but also images to(More)
Consumer health informatics represents a diverse field devoted to the development, implementation, and research on telecommunication and computer applications designed for consumers to access information on a wide variety of health care topics. This technology, both hardware and software, is part of a growing trend toward empowering consumers to take a more(More)
A MUMPS comuter program, which stores and retrieves quality-control data from all automated and manual work-station in the laboratory, has been developed as part of a laboratory information system. Tabular displays, Levey-Jennings charts, and summary statistics are available on a real-time basis. Significant economy over previous manual methods has been(More)
