title: Prospective study of decubitus ulcers in two long term care facilities.
abstract: The incidence and prevalence of decubitus ulcers, and their complications and microbiology were studied prospectively in two large long term care facilities in Winnipeg, Manitoba between January 1, 1989 and December 30, 1990. The initial prevalence of decubitus ulcers was 2.6 and 1.6% at the two institutions, with an incidence of 3.4 and 4.8 per 100,000 resident days, respectively. The incidence of decubitus ulcer infection was 1.4 per 1000 ulcer days. The only other complication identified was in one resident who required an indwelling catheter to permit ulcer healing. An average of 2.4 organisms grew from surface swabs of ulcers; anaerobes were isolated from 14% of cultures. Aspirates from clinically noninfected ulcers had bacteria isolated in 30% of specimens. Two-thirds of organisms isolated were considered potentially pathogenic. Concurrent bacteriuria was present for 75% of sampling episodes. Organisms present in the urine were simultaneously isolated from decubiti in only 5% of specimens. Decubitus ulcers are uncommon in long term care institutions. The urinary tract of the bacteriuric elderly appears to be an infrequent source of organisms colonizing decubiti.
