Regional and Institutional Variation in the Initiation of Early Do-Not-Resuscitate Orders

Abstract

Do-not-resuscitate (DNR) orders are an important step in decision making about aggressiveness of care for patients in hospitals. The use of DNR orders is known to vary with patient characteristics, but few studies have investigated the role of hospital factors or of regional variation. We examined these influences on the use of early DNR orders (written or =80 years). In multivariate analyses, the odds of having early DNR orders written were significantly lower in for-profit (vs private nonprofit) hospitals, higher in the smallest (vs the largest) hospitals, and lower in academic (vs nonacademic) hospitals. Standardized rates of DNR order use varied 10-fold across counties. The highest rates were among patients from rural areas. However, variation in use did not correspond well to county population, hospital bed availability, or population density. Hospital characteristics appear to be associated with the use of DNR orders, even after accounting for differences in patient characteristics. This association reflects institutional culture, technological bent, and physician practice patterns. If these factors do not match patient preferences, then improvements in care are needed.
