^aAdherence was defined as collection of a rectal surveillance swab for KPC culture within 3 calendar days of admission. Median time from admission to availability of swab culture results was 3 days (interquartile range, 2–4 days).

^bAdherence was measured 3–6 days per week at each LTACH. Three LTACHs cared for KPC-positive patients on patient cohort wards. The fourth LTACH cared for KPC-positive patients in private rooms. The percentage of KPC-negative patient-days on a KPC cohort floor or in a room with a KPC-positive patient was 13% (5109/40 777).

^cHigh-acuity unit rooms only, where universal contact isolation was in effect.
