Abstract

Several studies have described a need for a valid statistical methodology to facilitate interhospital and intrahospital infection rates for their operative procedures. Physician awareness of postoperative surgical-site infection rates has been demonstrated as an effective means to reduce infection rates in both high- and low-risk surgical patients. This article presents a new software program that allows for simple data entry and provides results including the gamma statistic, sample size, variance, standard error, and Z value and P value of the gamma result. This software also provides a data interpretation table, allowing infectious disease department physicians or staff to determine if a significant relation exists between operative procedure infection rates and patient risk factors.
