RESUMEN
AIM: Determine the effect of an intervention to reduce the length of stay (LOS) in appendectomies. METHODS: A four-quarter quality improvement initiative was developed after approval by the facility Quality Management Department, including educational sessions about the best practices regarding the hospital care for patients with appendicitis and recommendations to limit the LOS for no complicated appendicitis unless associated conditions were present, monitoring of the LOS and feedback to the staff and leaders. RESULTS: 692 appendectomies were performed, 365 (52.7%)) of them during the intervention. The mean LOS was 3.94 days with a decreasing trend during the study period. The complicated appendicitis had a mean LOS of 6.42 days (SD, 3.85) during the baseline and 5.27 days (SD 2.50) during the intervention (p=0.03), representing a 17.9% reduction. The not complicated appendicitis during baseline had LOS of 3.82 days (SD 4.17) with a subsequent reduction to 2.95 days (SD 1.53) in the intervention. The total saving bed days during the intervention were 338.04 days, which 254.04 days (75.2%) were in non complicated appendectomies. One patient required readmission during the intervention because of an organ space surgical site infection, with proper recovery after antibiotic treatment. CONCLUSION: Our study provides evidence about the possibility to optimize the bed use with a simple educational intervention, and should be considered a step to achieve additional reductions in the hospital stay of patients who undergo laparoscopic appendectomies.
