Abstract

Objective: To analyze the trend of bloodstream infections associated with central venous catheter insertion in the Chilean healthcare system. Materials and Methods: Ecological study with trend analysis of the annual prevalence of bloodstream infections associated with central venous catheter insertion in Chilean hospitals from 2001 to 2019. For univariate analysis, frequencies, percentages, mean and standard deviation were used. For bivariate analysis, the X2 test and Student’s t-test were used, according to the nature of the variables, with a significance level of p<0.01. For the trend analysis, a linear trend analysis of the annual prevalence was performed using the Prais-Winsten autoregression method, which allows the estimation of a global trend of a series of data of a quantitative indicator. The annual percent change (APC) and its 95% confidence intervals (CI-95%) were calculated. Results: A total of 27,197,232 cases were analyzed. An overall increasing and significant trend was observed throughout Chile (APC=0.00370; 95% CI=0.0034 / 0.0039), with an average interannual growth rate of 5%. In general, the analysis by region shows a static trend. Conclusion: Central venous catheter-related bloodstream infection is a growing complication in Chile. Therefore, it is necessary to develop programs and interventions to control the progression of this complication. © 2023, Universidad de Concepcion. All rights reserved.
