Oncologic research and computerized data retrieval.

Abstract

A computer-based data retrieval system for clinical research in oncology is described. The system has been designed to enable busy clinicians to retrieve and analyze data directly without major involvement of a computer specialist. The system uses texts similar to those in daily practice. In most situations no code is printed. The other important feature of the system is its ability to analyze clinical data in the form of tables, frequency distribution, etc. It may also furnish actuarial characteristics of the total population or subpopulations. Mathematical functions are calculated easily. Amendments and updating are simple enabling follow-up data to be incorporated. The system is under use for about 2 years and appears to be a versatile tool in the field of clinical research.
