Objectives. Health care-related infections are a public health problem, among them surgical site infection (SSI) are the most frequent in hospitals. The objetive of this study was to assess the effect of the compliance to antibiotic prophylaxis protocol on the incidence of surgical site infection in hysterectomized patients.
Material and methods. A prospective cohort study was carried out between October 2009 and December 2018. The incidence of SSI was studied after a maximum period of 30 days from the moment of surgery. The degree of adequacy of antibiotic prophylaxis in hysterectomy and the effect of its inadequacy on the incidence of infection was evaluated using relative risk (RR) adjusted with a logistic regression model.
Results. A total of 1,025 interventions were studied in 1,022 women. The cumulative incidence of SSI was 2,1% (n = 22). The most frequent etiology of infection was Escherichia coli (23.1%) and Proteus mirabilis (23.1%). Antibiotic prophylaxis was indicated in 1,014 interventions (98.9%) being administered in 1,009 of them (99.5%). The adherence to the protocol was 92,5%. The main cause of non-compliance was the time of onset (40.9%), followed by the choice of the antibiotic (35.2%). The effect of inadequate prophylaxis on the incidence of infection was RR = 0.9; 95% CI 0.2-3.9; p> 0.05.
Conclusions. The adequacy of antibiotic prophylaxis was very high, with a low incidence of surgical site infection. No association was found between adequacy of prophylaxis and incidence of infection in hysterectomy. The continuous improvement of epidemiological surveillance in gynecology should be emphasized.
