RESUMEN
Postoperative pulmonary complications (PPCs) increase the hospital length of stay (LOS) and the cost of healthcare associated with surgical procedures. Strategies to reduce PPCs begin before surgery and continue in the postoperative period. Fissios App© is a smartphone application that contains perioperative medical advice and a structured respiratory physiotherapy program. The objective was to implement the use of this app in a group of patients scheduled for a thoracic surgical procedure and determine its efficacy in reducing PPCs. This was a quasi-experimental study in which all patients attended a face-to-face respiratory physiotherapy program, and the intervention group used Fissios App© as a complement. We prospectively recorded the postoperative evolution of both groups, analyzed the categorical differences and quantitative variables, and created a binary logistic regression model. We recruited 393 patients (131 intervention and 262 control). The intervention group had a lower incidence of PPCs (12.2% versus 24% in the control group, p = 0.006), a shorter LOS (a median of 3 days (IQR = 2-5) versus 4 days (IQR = 3-6, p = 0.001) in the control group), and a reduction in the risk of developing PPCs by 63.5% (OR: 0.365, 95% CI: 0.17-0.78). The use of Fissios App© improved the clinical outcomes after surgery and reduced the probability of developing PPCs.
