Low-cost comprehensive data system for cardiac patients.
Functional systems to collect, store and retrieve clinical, hemodynamic, and angiographic information are needed to serve clinical research and quality control in the cardiac laboratory. Computers are ideally suited for this application, but high investment and maintenance costs are a barrier for their wider use. A low-cost data processing and procedure reporting system was developed using a programmable calculator, a floppy disk drive, and a printer. Files have been started on 750 consecutive adult patients undergoing cardiac catheterization and angiography. Each file contains a clinical profile (CP), angiographic interpretation (Al), and hemodynamic data. CP and Al are coded according to a data base definition appropriate for patient care (procedure report) and research analysis. Data input is simplified by the use of multiple choice forms and prompts appearing on the calculator alphanumeric display. One floppy disk may hold 400 patient files. Immediate access to stored information for cross reference, computations, and statistical work is possible in all patients, a patient category, or an individual case. Stored items may be retrieved in coded form for analysis or translated into sentences to generate a multiple-copy procedure report. Follow-up information may be subsequently added to the patient file. Operation requires minimal training and little expertise in computer technology.
