    Abstract:
    The purpose of this study was to investigate the factors effecting on an observation time needed for outpatient treatment of acute alcohol intoxication. Subjects were 181 patients with acute alcohol intoxication who visited at the Center of Critical Care Medicine of St. Luke's International Hospital from June 1999 to May 2000. One of 181 patients was admitted as an inpatient. The mean observation time of 180 outpatients was about 3 hours. Ninety-nine outpatients (55%) needed observation time less than 3 hours. High level of Blood Alcohol Concentration (BAC), moderate consciousness disorder (Japan Coma Scale; JCS 10-30), and severe consciousness disorder (JCS 100-300) were significant factors to increase observation time more than 3 hours. Gender and age were not significant factors associated with more-than-3-hour observation time. Observation time of mild consciousness disorder (JCS 1-3) was significantly decreased against that of clear consciousness (JCS 0). Effects of acetaldehyde might be related to elongation of the observation time among clear consciousness patients. Medical resources of emergency medicine in Japan are not enough in some cases (such as few beds and small numbers of staffs), and it is occasionally difficult for patients to stay at a emergency unit for a long time. And the number of hospitalization for acute alcohol intoxication is likely to increase in Japan. Consideration on the attributes, such as BAC or patient's consciousness, associated with observation time of outpatient treatment might be useful to reduce the number of hospitalization and the cost of medical care for acute alcohol intoxication in emergency medicine.
