a
Data were pooled from the California Health Interview Survey for 2003, 2005, and 2007 and averaged from OSHPD discharge files for 2004, 2005, and 2006.
b
Age groups 18-44 y and 45-64 y are combined for this rate because of the small prevalence of congestive heart failure in the population.
c
Rate per 100,000 people in the population.
d
Rate per 100,000 people reporting ACSC in the population.
