Estimated Effect of Vaccination Rate on Mortality and Hospitalization Outcomes

P&I = pneumonia and influenza.

Model controlled for linear trends for calendar years, nursing home, and city and was weighted by the number of nursing home residents at risk for hospitalizations and deaths for each week.

Number of long-stay (>100 days) fee-for-service (FFS) residents hospitalized from a given facility in a given week divided by total number of long-stay FFS residents in that facility in corresponding week multiplied by 1,000.
