The more hospitals share patients, the more likely they are to have a problem with carbapenem-resistant Enterobacteriaceae (CRE), especially if long-term acute care hospitals (LTACHs) are in the mix, according to a state-wide investigation from Illinois.
Greater hospital centrality was independently associated with higher rates overall, and sharing four or more patients with a long-term acute care hospital (LTACH) in the 3-month study window doubled the rate of CRE cases.
Although it’s possible that was because of chance (P = 0.11), the link between LTACHs and CRE “is consistent with prior analyses that have shown the central role LTACHs have in” spreading the organism, said the researchers, led by Michael Ray of the Illinois Department of Public Health (Clin Infect Dis. 2016 Aug 2. pii: ciw461).
Patients often spend weeks in LTACH facilities for ongoing, serious health problems. The severity of illness, long stay, and sometimes chronic antibiotic use increase the risk of CRE exposure, and the team found that many LTACH patients are colonized.
“These findings have immediate public health implications. … Early interventions should be focused on the most connected facilities, as well as those with strong connections to LTACHs.” When one hospital has an outbreak, facilities that share its patients need to swing into action screening new admissions and taking other steps to prevent regional spread, the team said.
Meanwhile, “state-wide patient-sharing data, which are now increasingly available through sources like the Healthcare Cost and Utilization Project, provide an important way to assess hospital risk of CRE exposure based on its position in regional patient-sharing networks,” they noted. “Public health can play a critical role in identifying tightly connected hospitals and educating personnel at such facilities about their risk and need for enhanced infection control interventions.”
The team came to their conclusions after linking Illinois’ drug-resistant organisms registry with admissions data for 185 hospitals. About half reported at least one CRE case over 3 months, with a mean of 3.5 cases per hospital.
There was an average of 64 patient-sharing connections per facility, with a minimum of one connection and a maximum of 145 connections. Each additional patient two hospitals shared corresponded to a 3% increase in the CRE rate in urban facilities and a 6% increase in rural ones. The investigators didn’t explain the discrepancy, except to note that rural areas don’t have LTACHs.
Almost two-thirds of hospitals reporting CRE were in Chicago-area counties; almost half had shared at least one patient with an LTACH, and 21% had shared four or more.
CRE cases were an average of 64 years old, and equally distributed between men and women and black and white patients.
