aHigh %PNSP was defined as >5 percentage points above the surveillance area % of penicillin-nonsusceptible pneumococci (PNSP) ; low as >5 percentage points below the surveillance area %PNSP; average as <5 percentage points above or below the surveillance area %PNSP.
bAdjusted inpatient days were calculated as Inpatient Days + (Inpatient Days * [Outpatient Revenue/Inpatient Revenue]).
cRef=Referent group.
ICU, intensive-care unit.
