A national survey of observation units in the United States
The American Journal of Emergency Medicine(2003)
摘要
The objective of this study was to survey the use of observation units (OUs) in the United States. A written survey was mailed to every third hospital (sequential by zip code) in the United States. There was a 32.9% response to the survey (522 of 1588 hospitals). A total of 18.8% of hospitals had an OU with another 11.6% planning to open an OU. Those hospitals that had OUs had a higher overall ED census, higher rate of diversion of ambulances, and were more likely to be in metropolitan areas (P <.05), but there was no relationship to payor mix or to ED hospital admission rate. The OUs were characterized by a mean 4.8 years in existence, 57.3% ED administratively responsible, 59.4% ED clinically responsible, a mean of 1330 patients per year, an average length of stay of 15.3 hours, s 4.2 nurse-to-patient ratio, and 22.3% hospital admission rate.
