title: Combined surgical audit by microcomputer involving units in four health regions.
abstract: General surgeons from hospitals in four well-separated health districts collected audit data about their patients using common software. They pooled their results in order to make comparisons between their practices. Data on 22,497 admissions including 17,473 operations were available. The data were found to be easy to collect and analyse using this program. There were significant differences in overall complication rates between the four centres, but these seem to be explained by differences in the emergency workload, case mix, and age range of the population treated. A study of inguinal hernia repairs and appendectomies showed low complication rates with no significant differences between centres, with the single exception of a higher incidence of wound problems in one centre. Because of the multiplicity of factors affecting them, complication rates could only be properly understood in a professional surgical context. Isolated figures would be open to damaging misrepresentation. Meetings between surgeons well armed with their own results seem to be the best way to forward the audit process.
