Fatores de risco para infecções relacionadas à assistência à saúde causadas por enterobactérias produtoras de carbapenemase portadoras do gene blaKPC

Abstract

Enterobacteria producing carbapenemase carrying the blaKPC gene (EPC-KPC) spread rapidly and, by limiting the therapeutic options for infected patients, end up associated with a high mortality rate. In the hospital environment, the early identification of risk factors for Healthcare associated Infections (HAI) caused by the blaKPC gene are important for the control of dissemination among patients, professionals and/or environment. However, there is still no consensus in the literature on which risk factors are directly associated with HAI caused by EPC-KPC. This study aimed to evaluate the risk factors associated with Healthcare associated Infections caused by EPC-KPC in the hospital environment. It was a case-control study that consisted of a sample of 82 infected patients and 164 controls, totaling 246 patients. Patients in the control group were randomly selected and matched by sex and proportional age. The data were collected by the Automated System of Control of Hospital Infection and electronic patient record. The results showed that patients previously colonized by gramnegative microorganisms (OR: 10.7, 95% CI: 2-60, p = 0.007), those with cancer (OR: 20.8, 95% CI: 4-120, p
