Abstract : This study was conducted to determine if case severity is significantly related to surgical mortality and morbidity outcomes. Inpatient records were reviewed to retrieve information on case severity and whether mortalities or complications had occurred during the surgical procedures. There was a significant association between case severity prior to surgery and surgical outcome. The author highly recommends incorporating case severity information into outcome predictions to better assess deviations from predicted outcomes as a means of physician care quality assessment.
