Admission into Hospital - ED versus Routine: In 1996,¹ approximately 42.3% of hospitalizations were routine--patients entered the hospital directly. The second most common source of admission was through the emergency department (ED), comprising about 40 percent of admissions. In 2008, about half of all admissions through the ED, and 40 percent routine admissions. The remaining admissions were transfers from another hospital or health care facility, or of unknown origin. The percentage of people admitted to the hospital through the ED increased for all age groups. While older individuals were more likely to be admitted into the hospital through the ED, increases (between 1996 and 2008) were largest for younger patients aged 0-14.

The top 10 reasons for hospitalization among patients admitted through the ED revealed serious conditions. Pneumonia is the most frequent reason. Three of the top 10 conditions related to the circulatory system: heart failure, acute myocardial infarction, and cardiac arrhythmia. The other top reasons include stroke, cellulitis, septicemia, COPD, appendectomy, and other respiratory infections.

Hawaii is more likely to admit patients via the ED than comparison U.S. hospitals (U.S.: 44%, 2006).
