Adjusted Associations Between Hospital Characteristics (Centrality and Long-Term Acute Care Hospital Sharing) and Carbapenem-Resistant Enterobacteriaceae Rates (per 10 000 Patient-days) Among Short-Term Acute Care Hospitals in Illinois

Hospital Characteristic	Rate Ratio	95% Confidence Interval	P Value
Degree centrality, by region^a
Chicagoland^b	1.027	1.002–1.052	.03
Non-Chicago urban^b	1.025	1.002–1.048	.03
Rural county^b	1.056	1.030–1.082	<.0001
Long-term acute care hospital sharing^a
≥4 vs <4 patients	2.08	.85–5.08	.11

Multivariable model is adjusted for each hospital’s total number of beds and county type–degree centrality interaction.

For degree centrality, rate ratio represents increase in carbapenem-resistant Enterobacteriaceae rate for each additional hospital connection.
