Burn units' share of Canada's total burn care.

The share of total hospital Canadian burn care provided by 17 of Canada's 27 present burn units increased marginally to 18.3% in 1991 from 17.0% in 1981 (p = 0.0506), and the mortality rate decreased from 5.6% in 1981 to 3.5% in 1991 (p < 0.05). In 10 units providing serial data, patients with burns undergoing ventilation therapy for a concomitant smoke inhalation injury increased from 6.3% (n = 58) of 1981 admissions to 11.1% (n = 73) of 1991 admissions (p < 0.05). In 1991 Canada's 27 burn units treated 32.4% of Canada's hospitalized patients with burns and provided 50.6% of hospital burn care days. Although the total number of patients with burns hospitalized in Canada decreased by 35% from 7923 in 1981 to 5161 in 1991 (32.6 to 18.9 per 100,000 population), with a proportional decrease in patients treated in burn units, the requirement for intensive care unit capability to treat patients undergoing ventilation therapy has remained the same or is greater and must be preserved as burn units shrink.
