Patient and hospital demographics do affect the outcomes of patients undergoing inpatient cholecystectomy. Although male gender, African American race, Medicare-insured status, and large, urban hospitals are associated with less favorable cholecystectomy outcomes, only increased age predicts increased morbidity, whereas female gender, laparoscopy, and cholangiogram are protective. Increased age, complications, and emergency surgery predict mortality, with laparoscopy and intraoperative cholangiogram having protective effects.
