Methodological, technical, and ethical issues of a computerized data system.
This report examines some methodological, technical, and ethical issues which need to be addressed in designing and implementing a valid and reliable computerized clinical data base. The report focuses on the data collection system used by four residency based family health centers, affiliated with the University of Massachusetts Medical Center. It is suggested that data reliability and validity can be maximized by: (1) standardizing encounter forms at affiliated health centers to eliminate recording biases and ensure data comparability; (2) using forms with a diagnosis checklist to reduce coding errors and increase the number of diagnoses recorded per encounter; (3) developing uniform diagnostic criteria; (4) identifying sources of error, including discrepancies of clinical data as recorded in medical records, encounter forms, and the computer; and (5) improving provider cooperation in recording data by distributing data summaries which reinforce the data's applicability to service provision. Potential applications of the data for research purposes are restricted by personnel and computer costs, confidentiality considerations, programming related issues, and, most importantly, health center priorities, largely focused on patient care, not research.
