Note. ACS = ambulatory care—sensitive. Ellipses indicate that data were not available.
Results from Poisson regression of the form log(# of hospitalizations) = B0+B1(year), where year is a linear term ranging from 0 (1999) to 9 (2007), and the mean annual percentage change = 100 [exp(B1)-1]. Population size (by sex or age group) is used as an offset.
Premature mortality is defined as < 65 y.
All government and contracted hospitals, per 10 000.
