Abstract

Objective: We describe the national organization and distribution of intensive care services within the Veterans Health Administration (VHA), the largest single integrated health-care system in the United States.

Data Sources: Data come primarily from the 2004 Survey of Intensive Care Units in VHA, an electronically distributed survey of all ICUs in the VHA. Medical directors and nurse managers from all 213 ICUs in the VHA responded to the survey. In addition, we extracted data on the number of ICU admissions and unique veterans served from national VHA databases.

Results: The VHA has a geographically dispersed, multilevel system of care with variation in geographic access for eligible veterans (varying from 3.1 to 3.5 ICU beds per 1,000 patient discharges) and variation in service provision (from 10 to 19 level 1 ICUs across four regions). Level 1 ICUs are the highest tertiary-level ICUs, with the full range of subspecialty care. The proportion of beds associated with VHA-developed ICU levels of care ranges from 55% level 1 beds in the Northeast to 73% in the South, while level 4 beds represent 4% of all ICU beds in the South and 10% in the Midwest.

Conclusions: Overall, the VHA system has a fair amount of regional variation, but level 1 ICUs are available in all geographic regions, and there are regional clusters of all levels. Adopting a four-level system for rating ICUs may assist in monitoring and assessing the quality of care provided in the smallest, most rural facilities.
