(1) Bed Size

Note: The number of hospitals and respondents in each breakout category is shown in each table (e.g., the number of hospitals and respondents by bed size). However, the precise number of hospitals and respondents corresponding to each data cell in a table will vary because hospitals may have omitted a specific survey item and because of individual nonresponse/missing data.
