Most of the 410 physicians interviewed (76%) were men; 51% were clinical specialists, 30% were general practitioners, and 19% were nursing home physicians (Tables 1 and 2). Of all physicians, a weighted percentage of 52% (95% CI, 48% to 57%) had ever practiced terminal sedation. This percentage was 55% (CI, 49% to 62%) for clinical specialists, 48% (CI, 39% to 57%) for general practitioners, and 75% (CI, 64% to 83%) for nursing home physicians. We asked all interviewed physicians to estimate the total number of times they performed terminal sedation in 2000 and 2001. These numbers were extrapolated to the total number of 140 377 deaths in 2001 by multiplying them with the weighting factor for each specialty and assuming that the numbers were similar for the 5% of deaths covered by hospital doctors from specialties other than the ones included in our study. This extrapolation suggests that physicians used terminal sedation in 10.0% (CI, 9.1% to 10.8%) of all deaths in that year. Of the 10.0% of deaths preceded by terminal sedation, 5.5% (CI, 5.0% to 6.1%) were attended by clinical specialists, 2.5% (CI, 1.9% to 3.2%) by general practitioners, and 2.0% (CI, 1.7% to 2.2%) by nursing home physicians.
