Eventos adversos postquirúrgicos asociados con características sociodemográficas y de salud en un hospital de tercer nivel

Abstract

Objective: to analyse the postoperative adverse events (PAE) in patients undergoing a surgical intervention in a third level hospital. Methods: a descriptive, observational and ambispective study, including patients undergoing surgery, with a complete surgical record (n= 322). Convenience sampling was conducted in a Mexican hospital. A data collection card was used in clinical records, and post-surgical follow-up phone calls were made. Risk was analysed through odd ratios, and there was association analysis through Chi square test and binary logistic regression, considering a 95% confidence interval and < 0,05 for statistical significance.Results: the study included 274 patients (85.1%). Their mean age was 55 years (SD: 16.37), 51.5% were female, 67% were at poverty level, and 70.5% presented ≥ 1 comorbidities, with hypertension (40.5%) and diabetes (29.9%) as the most common. A 38% of the patients had excess weight, and 29% presented Obesity Grade I. A 21.9% developed ≥ 1 PAE; the most frequent were surgical site infections (39.1%) and urinary infections (23%). It was calculated that the OR for the risk of presenting a PAE was 10.1 higher when the hospital stay was prolonged (CI95% 2.003-50.924), and there was an OR of 4.70 times more risk when faced with emergency surgery (CI95% 2.558-8.977). More neurosurgical complications p= 0.045), haemorrhages and readmissions (p< 0,001) were found with a higher body mass index.Conclusions: there are factors of risk for developing PAE, such as prolonged hospital stays, undergoing an emergency surgery, and presenting a high body mass index.
