title: Establishment the cost-effectiveness through set criteria of laparoscopic cholecystectomy.
abstract: OBJECTIVE
  To assess the set criteria of laparoscopic cholecystectomy (LC) in reducing the length of hospital stay (LOHS), and total treatment expenditure.
  
  
  METHODS
  The measurement outcomes were prospectively analyzed through the medical record, and self questionnaire of the patients.
  
  
  RESULTS
  During the 1-year trial, a total of 122 patients were scheduled for LC. Among these, 85 cases had met the set criteria of low risk clients of both preoperative indicator of a) American Society of Anesthesiologists (ASA) class 1 or 2, and postoperative indicators of b) no surgical drainage, and c) no immediate complication, while 37 cases were excluded due to ASA class 3 or 4, and various reasons. Distributed by the duration of hospital stay, the patients were classified in to three groups; group A was overnight hospital stay, 15 of 85 subjects (17.6%), group B was short hospital stay (within 3 days), 51 of 85 subjects (60.0%), and group C was long hospital stay (more than 3 days), 19 of 85 subjects (22.4%). The mean length of hospital stay (LOHS) was 24 +/- 1.61 hours in group A, 55 +/- 11.16 in group B, and 108 +/- 21.59 in group C, while the average total expenditure was 531.22 +/- 111.09, 665.5 +/- 133.35 and 812.33 +/- 158.62, respectively. For the overnight hospital stay group, the LOHS and the total treatment expenditure was significantly lower the other groups (p < 0.001). The majority of the overnight hospital stay group had rated the patient satisfaction as excellent.
  
  
  CONCLUSIONS
  The set criteria of laparoscopic cholecystectomy (LC) are helpful and establish the cost-effectiveness in terms of reduction of LOHS and total treatment expenditure.
