Methodology Notes: 

    Ambulatory care-sensitive conditions are conditions for which good outpatient care can potentially prevent the need for hospitalization or for which early intervention can prevent complications or more severe disease. Potentially preventable hospitalizations were defined consistent with those used by the Agency for Healthcare Research and Quality (AHRQ, Version 4.4). They include diabetes, short-term complications; diabetes, long-term complications; chronic obstructive pulmonary disease; hypertension; congestive heart failure; dehydration; bacterial pneumonia; urinary tract infections; angina without procedure; uncontrolled diabetes; adults asthma; and lower extremity amputations among patients with diabetes.
