Description of a universal data entry and retrieval program for vascular surgeons

Until recently, vascular surgeons have had to make judgments based on an impression of their experiences rather than upon the actual facts. Presently, with the simplified and less costly use of computers, the establishment of a computerized data base is feasible. Our goal had been to develop a system suitable for micro- or minicomputers which can be programmed in ordinary English and, once in place, requires essentially no knowledge of computers or computer programming for its successful use. Such a data base could put to an end the comparison of series that are truly incomparable because of differences in data classification and presentation. For example, in the case of a femoropopliteal bypass, which eventuates in a successful thrombectomy, some call it a success, some call it a failure, and some list it as both a success and failure. Many ignore the thrombectomy entirely and choose to place the final result in the plus category of "limb salvage." One seemingly insurmountable problem has been that because practice patterns differ, it has been necessary to design individual computer programs. A programmer has been required to write each of these programs, with consequent great expense and delay. While there are programs available for establishing a data base, they largely have required the use of large computers. Using such a computer implies a time sharing system with frustrations in regard to both availability and ease of use.
