On-line computer storage, retrieval, and reporting of coded angiographic data

Interpretations of angiographic images have been coded and stored using an on-line computer terminal for seven years. Decoded angiographic information is incorporated in computer-generated reports which are printed on demand after completion of cardiac catheterization procedures. Currently, almost 5,500 cases are stored in an off-line data base which has been designed to help identify patterns with prognostic potential. Also, the program has helped standardize angiographic nomenclature, saved much clerical time, and virtually eliminated clerical errors. The program interacts with other software in the hospital, avoiding repetitious entries. The advantages and shortcomings of the program and commonly used approaches to computer storage/retrieval of radiographic information are described.
