Use of the personal computer in clinical research.

Personal computers are quickly becoming items of everyday use. More physicians' offices are using computers for billing and patients' records. Others have purchased computers for their word processing capabilities. These computers can be used for archives of medical case records or to collect and collate data for clinical research. This article focuses on how we use a personal computer for organization and management of clinical research projects. Included is a description of how we organize a research project, gather data, write computer programs, enter data into the computer, and generate and display reports. The use of a template program and a personal computer permits creation of individual programs without the aid of a professional programmer. When a single data-management program is used, five or six research projects can be carried out at a cost comparable to that of one project using a large computer and professional programmers.
