A case information management system for clinical trials

We have devised and implemented a computer-based case information management system which allows the storage, maintenance and analysis of data from any clinical trial. Before the clinical trial begins, the medical and paramedical staff devise and structure a list ot questions which are answerable by (a) a series of up to 10 multiple choices; (b) a date; (c) a number; (d) a phrase or brief sentence. These questions are allotted to forms designed to make the collection of data as efficient as possible; for example, much of a patient's history can be collected by a form which the patient fills out himself. The system is sufficiently simple so that, after a few hours' training, inexperienced students are able to enter all data into the computer. The analysis programs allow one to cross-correlate data from the first three types of questions automatically, and to obtain printouts of histograms and scattergrams correlating the appropriate types of data. These features make this approach cost effective because relatively little time of the medical and paramedical staff is required to organise and implement a clinical trial and because data entry can be performed by previously untrained personnel.
