Geographic Variation in Pneumonia and Influenza in Long-Term Care Facilities: A National Study.

There is large U.S. county-level geographic variation in pneumonia and influenza (P&I) hospitalizations among short-stay and long-stay long-term care facility (LTCF) residents. LTCFs in counties in the Southern and Midwestern regions had the highest rates of P&I from 2013 to 2015. Future research should identify reasons for these geographic differences.
