Audit of a surgical firm by microcomputer: five years' experience.

From 1982 to 1986 inclusive work of one surgical firm was audited with a microcomputer. Data were recorded on 4336 patients having 3355 operations, who were under the care of one consultant in a general surgical unit; fifty items of information were recorded on each patient, allowing a wide range of analyses to be performed--for example, the number of admissions and operations, grades of operation, diagnostic grouping, complications, and complication rates associated with individual surgeons. Data collected for the audit provided a valuable baseline for the unit, defining aspects of practice that could be reviewed and improved. During the audit the overall rate of complications as a percentage of admissions fell significantly from 13% to 9% and the rate of postoperative complications decreased significantly from 16% in 1982 to 11% in 1986. The incidence of chest and wound infections also decreased significantly. The system was improved by using the data to produce discharge summaries as well as audit; the microcomputer thus became an integral part of the office work of the unit.
