Heart Attack Indicator:
Hospitalizations
Measure
: Crude annual heart attack hospitalization rates
Data used in the calculation of these measures were collected by the Oregon Association of Hospitals and Health Systems for the Hospital Discharge Index (HDI). The HDI provides a central database of all Oregon hospital discharges for public health surveillance and hospital policy analysis. Information on emergency room visits, urgent care, outpatient surgery and clinic visits is not included in this database.
Before EPHT,
there was no single heart attack surveillance system in place in the US. Mortality was currently the sole descriptor for national data for heart attacks. Estimates of incidence and prevalence of heart attacks and coronary heart disease were largely based on survey samples or large cohort studies.
Tracking heart attack hospitalizations will provide more information than death certificates or surveys, and will help with examination of time and geographic trends in heart attack hospitalizations, and evaluation of differences by age, gender and race/ethnicity.
The table, graphs and map below show crude heart attack hospitalization rates for Oregon from 2000 to 2006.
Crude hospitalization rates presented below are slightly higher than rates that are adjusted to the age structure of the standard 2000 U.S. population. This is due to the fact that heart attacks are more prevalent among older people and Oregon has a higher proportion of older people than the United States in general.
From 2000 to 2006, the crude rate of heart attack hospitalizations significantly decreased. This drop in heart attacks has been observed throughout the United States and was linked to a broader use of preventive medication and declines in risk factors such as smoking.
Besides the similar decrease in heart attack hospitalizations for Oregon and the United States as a whole, heart attack hospitalization rates were significantly lower in Oregon compared to the rest of the country. The reasons for Oregon’s low heart attack rates are not clear.
Crude rates were significantly higher in rural compared to urban counties, but the drop in rates over time was also more pronounced in rural counties. In other words, heart attack hospitalization rates have become similar in urban and rural areas as a result of the decreasing rates in the rural counties.

Crude annual heart attack hospitalization rate for Oregon, by year from 2000 to 2006
____________________________________________________________________________________________________
Graph 2:
Crude annual heart attack hospitalization rates by county, averaged from 2000 to 2006
County rates are shown as blue squares, while the 95% confidence intervals (CI) are indicated by black horizontal lines. The vertical dotted line indicates the Oregon average rate.
A county rate is considered statistically higher (or lower) than the Oregon average if the entire CI lies above (or below) the Oregon average. If the CI includes the Oregon average, the county rate is considered statistically similar to the Oregon average.
