Active surveillance at the time of hospital admission for multidrug-resistant microorganisms among patients who had recently been hospitalized at health care facilities

초록

Background: This study aimed to investigate the epidemiology of multidrug-resistant microorganism (MDRO) carriage at hospital admission and to identify risk factors for MDRO influx into hospital settings. Methods: This cohort study was conducted at a 1,051-bed university-affiliated hospital in the Republic of Korea between July 1 and December 31, 2017. Active surveillance for MDRO carriage was performed within 48 hours of hospitalization in all adult patients who had prior hospitalization within the preceding 3 months. Results: During the study, 575 patients were admitted with a hospitalization history within 3 months. Active surveillance at hospital admission was performed in 192 eligible patients. Thirty-three (17.2%) patients with MDRO carriage were identified from active surveillance. In the multivariate logistic regression analysis, prior exposure to antibiotics within 90 days, hospitalization for >= 60 days before admission, cognitive dysfunction, percutaneous drainage, and underlying pulmonary diseases were identified as independent risk factors for MDRO influx. Conclusions: Our findings suggest a significant prevalence of MDRO acquisition at acute care hospital admission in patients who had been recently hospitalized. To control the spread of MDRO, collaborations among health care institutions and targeted screening at hospital admission according to patient risk factors are warranted.
