Objective To construct a casemix for patients undergoing abdominal surgery. Design A prospective longitudinal study. Wound infection was chosen as the target adverse event. A cluster analysis identified seven risk factors, which were then incorporated into a Boolean cluster (the casemix). Setting Royal Perth Hospital. Patients 1238 adults. Main outcome measures Wound infection, recurrent intraperitoneal sepsis, hospital stay, admission to the intensive care unit, and death. Results Measures of the severity of illness and the extent of co‐morbidity were more important in determining the risk of a poor outcome than was the identity of the diseased organ. Conclusions Estimates of severity of illness and extent of co‐morbidity should be included in any casemix based system for patients undergoing abdominal surgery.
