Ambulatory Care Sensitive Hospitalizations are hospitalizations for conditions where timely and effective ambulatory care can decrease hospitalizations by preventing the onset of an illness or condition, controlling an acute episode of an illness or managing a chronic disease or condition.

Hospitalizations are inpatient hospital stays as measured by stays that were completed during the specified year. The number of hospitalizations is often greater than the number of persons hospitalized since some persons are hospitalized more than once during a year.

Rates are per 10,000 population in the area for the specified year or years. Adding and subtracting the number shown after symbol from the rate creates an interval indicating that the true rate lies between the lower and upper bounds with 95% statistical confidence. A rate is not calculated and is shown by an "*" if there were less than 6 cases for the specified period and given diagnosis.

Population estimates are from the U.S. Census Bureau.

Leading Ambulatory Care Sensitive Conditions in the table are based on primary diagnosis only.

All Other Ambulatory Care Sensitive Conditions include primary and secondary diagnoses for iron deficiency anemia and nutritional deficiency, by secondary diagnosis for dehydration, and by primary diagnosis for all other conditions.
