Brief summary

The study questions are as follows: 1. Can Days Alive and Out of Hospital (DAOH) be collected from existing data sources for patients undergoing selected general surgical procedures, and does it discriminate between patients who suffer death or other important complications and those who don’t with sufficient sensitivity and specificity to be useful as a tool for monitoring the standard of care at a unit level? 2. Can a set of important technical complications be identified for selected general surgical procedures and their rate of occurrence collected from existing data sources and if so, is the combined rate sufficiently high for useful application in CUSUM analysis of individual surgeon’s technical performance? The objectives of the project are as follows: 1. To apply DAOH to a retrospective cohort of general surgical patients and explore the utility of this metric in measuring overall quality of care. 2. To measure the rates of surgical complications, and the effect of these complications on DAOH. 3. To measure the rates of surgical complications, and determine whether the incidence of these outcomes is high enough to create CUSUM graphs of surgical performance.

Interventions

This is a retrospective study of patients undergoing laparoscopic cholecystectomy and colectomy at Auckland City Hospital. Operative data (complications ) for these patients will be obtained from the Otago Audit System (a prospectively maintained registry). "Days Alive and Out of Hospital" (DAOH) values for each patient will be calculated using admissions and mortality data held by the New Zealand Health Safety Quality Commission. The follow-up period over which DAOH values will be calculated
