title: Impact of medical or surgical admission on outcomes of patients with acute cholecystitis.
abstract: Although acute cholecystitis (AC) is a surgical disease, patients with the condition may be admitted to medical-related services (MS). This may lead to delayed cholecystectomy thereby affecting outcomes and quality of care.
  
  
  
  Between July 2010 and March 2013, 329 patients under 70 years old presented to a community-based tertiary care hospital with AC and underwent same admission cholecystectomy. Outcomes were compared between patients admitted to MS and surgical services (SS).
  
  
  
  Two hundred fifteen patients (65.3%) were admitted to a MS. Patients under the MS had longer LOS (3.0 days vs. 2.0 days, p < 0.001), waiting time to surgical consultation (7.3 h vs. 5.0 h, p < 0.001) and to cholecystectomy (1.0, 0-2 days vs. 1.0, 0-1 day, p < 0.001), and increased hospital costs ($3685 vs. $4,688, p < 0.001) compared to the SS. Readmission and mortality rates were not significantly different between groups.
  
  
  
  Patients under 70 years old with AC undergoing cholecystectomy admitted to MS had increased LOS, delay to the operation, and hospital costs compared to those admitted to a SS. Admission of patients with AC to a SS needs to be emphasized to reduce costs and improve quality of care.
