Patients in Japan stay in the hospital significantly longer than those in the United States. This study investigates factors that may account for the difference from a sociocultural perspective. In an intensive case study on patients with uncomplicated acute myocardial infarction at a university hospital in Japan and its U.S. counterpart, the authors collected data from interviews with patients, their families, physicians, and other medical professionals and from medical, nursing, and billing records. Patients with comparable medical conditions were studied; U.S. patients stayed in the hospital for 8.8 days on average, Japanese patients for 25.0 days. The average total charge of hospitalization was 2.3 times higher in the United States than in Japan. Although length of stay is determined mainly by physicians' clinical judgment and by health care system factors, patients and their family members often actively participate in decision-making about discharge dates. This case study approach revealed how different health care systems manifest themselves in the individual patient's course of illness, which cannot be examined by macro-level comparison of nations' health care systems.
