Background and objective.

Burns are an important global public health problem, and its epidemiological aspects vary from one community to another.

The aim of the present study was to determine the associated factors with the development of intrahospital infections in adults with severe burns in a reference hospital in Peru through a 5-year retrospective study.

Methods.

Observational, analytical historical cohort type, quali-quantitative study. For the sample, the total number of patients with severe burn injuries was taken on count at the Daniel Alcides Carrión del Callao National Hospital, Lima, Peru, between 2014 and 2019, which was 45. A review was made of the clinical records of patients who complied with the inclusion criteria. Use bivariate analysis of independent variables between those exposed and not exposed to the variables of causes studied: age, hypoalbuminemia, comorbidities, percentage of total body surface burned and location of the lesion, and the Pearson correlation test and the U of Mann Whitney or the test of Kruskal Wallis.

Results.

A cumulative incidence of infected of 28.89% was obtained. In the bivariate analysis, factors associated with the development of hospital infections were: genital burns (RR 11.6; 95% CI 3.90-34.84; p <0.001), hypoalbuminemia (RR 0.07; 95% CI 0.03-0.16;

p = <0.001), percentage of total body surface burned (RR 92.9; 95 CI % 2.78-310; p = 0.011) and the age of the patients (RR 1.02; IC95% 0,98-1,05; p=0.017).

Conclusions.

In our environment, the main factors associated with the development of in-hospital infections in great burns patients were genital burns, hypoalbuminemia, the percentage of total body surface burned and the age of the patients.
