With the help of a surgical nurse and using data-processing techniques, a prospective clinical study was conducted to determine the @entity2737 rate in two hospitals in Calgary. The overall @entity295 rate was 5.2% and the clean wound rate 3.5%. The latter is the more meaningful figure as it allows for comparison between hospitals, specialties and individuals and is a good guide for hospital morbidity reviews. The groundwork for succeeding @entity2737 is laid in the operating theatre, and it is believed that @entity2737 would be reduced more by attention to Halsted's principles than by more rigid aseptic techniques. It is estimated that wound @entity295 costs the Province of Alberta 1.5 million dollars per year for hospitalization alone. This amounts to roughly  1 per @entity1 per year. The annual cost of a prospective study such as the present one is approximately  7000. This is equivalent to the cost of hospitalizing 24 @entity1 with @entity2737 for one week (at  300 per week). One dividend of a prospective study is an associated reduction in @entity281 rate. This reduction more than pays for the cost of the program.
