Description:Background.
In the United States, Klebsiella pneumoniae carbapenemase (KPC)–producing Enterobacteriaceae are increasingly detected in clinical infections; however, the colonization burden of these organisms among short-stay and long-term acute care hospitals is unknown.
Methods.
Short-stay acute care hospitals with adult intensive care units (ICUs) in the city of Chicago were recruited for 2 cross-sectional single-day point prevalence surveys (survey 1, July 2010–January 2011; survey 2, January–July 2011). In addition, all long-term acute care hospitals (LTACHs) in the Chicago region (Cook County) were recruited for a single-day point prevalence survey during January–May 2011. Swab specimens were collected from rectal, inguinal, or urine sites and tested for Enterobacteriaceae carrying blaKPC.
Results.
We surveyed 24 of 25 eligible short-stay acute care hospitals and 7 of 7 eligible LTACHs. Among LTACHs, 30.4% (119 of 391) of patients were colonized with KPC-producing Enterobacteriaceae, compared to 3.3% (30 of 910) of short-stay hospital ICU patients (prevalence ratio, 9.2; 95% confidence interval, 6.3–13.5). All surveyed LTACHs had patients harboring KPC (prevalence range, 10%–54%), versus 15 of 24 short-stay hospitals (prevalence range, 0%–29%). Several patient-level covariates present at the time of survey—LTACH facility type, mechanical ventilation, and length of stay—were independent risk factors for KPC-producing Enterobacteriaceae colonization.
Conclusions.
We identified high colonization prevalence of KPC-producing Enterobacteriaceae among patients in LTACHs. Patients with chronic medical care needs in long-term care facilities may play an important role in the spread of these extremely drug-resistant pathogens.
