Unplanned readmissions after surgery in a hospital in northern Brazil: prospective cohort

Objective: to analyze unplanned readmissions after surgical procedures and their risk factors in a large hospital in Northern Brazil. Method: prospective cohort, with data collected from medical records and at the bedside. Descriptive, bivariate and multiple analysis were performed using Poisson regression in Stata® v.16.0. Results: of the total of 486 patients, 1.47% were readmitted. The incidence of readmissions was 68 per 1,000 procedures (95%CI: 47.10; 93.85). In the adjusted analysis, the risk factors were not being white (RR: 2.06; 95%CI 1.13; 3.75), using implants in surgery (RR: 2.00; 95%CI: 1.05; 3.81) and procedures of the urology/renal specialties (RR: 3.17; 95%CI: 1.59-6.31) and gynecology (RR: 2.18; 95%CI: 1.06-4.49). Conclusion: the incidence of readmissions in this region is higher than in other regions. Demographic characteristics and type of surgical procedure were risk factors for the outcome.
