Efecto de un Plan de Mejora de Calidad y Seguridad Clínica en la incidencia de infección de sitio quirúrgico en apendicectomía. Estudio cuasi-experimental

Abstract

objective: Surgical site infections can be prevented. Control programs based on care bundle have proven to be effective in reducing its incidence. The objective of this study was to assess the effectiveness of a Plan for Quality Improvement and Clinical Safety in preventing the incidence of surgical site infection in patients undergoing appendectomy. Method: A quasi-experimental study was designed for analysis before and after the introduction of a Plan for Quality and Clinical Safety. Patients undergoing appendectomy were included. The incidence of surgical site infection was studied within 30 days from the time of surgery (maximum incubation period of surgical site infection). The effectiveness of the intervention was evaluated using the odds ratio (OR) adjusted with a logistic regression model. results: A total of 606 patients were included, of which 267 were operated in the period 2009-2010 (before the plan) and 339 in 2012-2013 (after the plan). The incidence of surgical site infection decreased after the plan from 6 to 5.6% (OR: 0.72; 95% confidence interval: 0.33-1.56; p = 0.839). There was greater compliance of antibiotic prophylaxis, preoperative preparation and adherence to hand hygiene after the introduction of the measures. Conclusions: Although the reduction in the incidence of surgical site infection after the measures adopted did not show statistical significant differences, important progress has been made in the compliance of antibiotic prophylaxis, adherence to hand hygiene and in the preoperative preparation.
