Table 2 Proportion of ICU patients with vasopressor use divided by total ICU admission and proportion of total ICU day on vasopressor over total ICU day

From: Temporal trends in the utilization of vasopressors in intensive care units: an epidemiologic study

  ICU admission (n) Patients on vasopressor, n (%) ICU day (n) Vasopressor day, n (%)
All ICU 72,005 19,575 (27) 272,271 59,811 (22)
Cardiac surgery ICU 15,631 8,601 (55) 54,212 25,710 (47)
Cardiac care unit 8,807 2,095 (24) 39,732 9,310 (23)
Medical ICU 16,863 2,864 (17) 57,782 8,397 (15)
Surgical ICU 19,997 3,846 (19) 85,065 10,533 (12)
Mixed ICU 10,707 2,169 (20) 35,480 5,861 (17)
  1. Proportion of ICU on vasopressors and vasopressor days
  2. Patients on Vasopressor (%) = Proportion of ICU on with vasopressors = (Total number of ICU on vasopressor/total number of ICU admissions) X100
  3. Vasopressor day (%) = Proportion of ICU vasopressor days = (Total vasopressor day/total ICU day) X100
