The association of bacteriuria with resident characteristics and survival in elderly institutionalized men.

Ninety-one elderly male residents of a skilled nursing facility were classified as nonbacteriuric (41%), intermittently bacteriuric (34%), or continuously bacteriuric (25%) on the basis of urine cultures obtained over a 3-year period. Bacteriuric and nonbacteriuric residents were similar in age, number of diagnoses and medications, and mobility. However, bacteriuric residents were more frequently confused or demented, whether continuously bacteriuric (78%) or intermittently bacteriuric (62%) compared with nonbacteriuric residents (42%) (p less than 0.04). In addition, bacteriuria was significantly associated with incontinence of bladder (96% of continuous, 66% of intermittent, and 25% of nonbacteriuric; p less than 0.001) and bowel (52%, 39%, and 5.5%, respectively; p less than 0.002). At 6 years of follow-up there were no differences in survival among the three groups. Urinary tract infection caused or contributed to only two (2.9%) deaths. Thus, in this population, bacteriuria was associated with higher functional disability but not with increased mortality.

Significance of pharyngeal colonization with aerobic gram-negative bacilli in elderly institutionalized men.

The prevalence of pharyngeal colonization with aerobic Gram-negative rods was studied on three occasions during one year in 68 elderly males resident on two long-term care wards. For the three surveys, pharyngeal carriage was identified in 43%, 43%, and 37% of residents. Each resident tended to remain either colonized or noncolonized. Pharyngeal colonization was associated with resident incontinence, the development of infection, and increased mortality during the year of observation.

Integrated university training program in geriatric medicine accredited and evaluated by the Royal College of Physicians and Surgeons of Canada.

The Federated Council for Internal Medicine recommended in 1981 "increased emphasis on geriatric medicine in the medical school curriculum, the medical residency, and continuing medical education." In the same year the first examination for a Certificate of Special Competence in Geriatric Medicine was held in Canada. This was the culmination of a process begun in 1974 to establish the subject as a subspecialty within Internal Medicine. The Royal College of Physicians and Surgeons of Canada set up a Specialty Committee which developed criteria for the accreditation of training programs. Candidates have to be eligible to sit for the certification examination in Internal Medicine before they can sit for the Certificate of Special Competence in Geriatric Medicine which is awarded only after passing both examinations. Thirty-nine individuals sat for the examination in its first five years of whom 26 were successful. These now form a nucleus of well-qualified internist-geriatricians who are developing academic programs in geriatric medicine in Canadian Medical Schools.

Twelve-month surveillance of infections in institutionalized elderly men.

Surveillance of infectious episodes in institutionalized elderly men permanently resident on two wards of a veterans' hospital was undertaken for a 12-month period. One-hundred eleven episodes were identified in 50 residents (74 per cent). The most frequent infections included lower respiratory tract infections (incidence 59/100 patient-years), febrile episodes with no source (43.4), skin and soft tissue infections (36.5), and gastroenteritis (33). Only pneumonia was associated with significant mortality. A specific etiologic agent was seldom identified other than for skin and soft tissue infections. Antimicrobial therapy was prescribed for 87 per cent of all infections. Ward staff absenteeism was associated with peak occurrences of infections in residents. Resident characteristics that correlated with infection were incontinence of bladder and of bowel. Mental status or degree of mobility did not correlate. While infections occur frequently in this population, mortality is common only with pneumonia. Infections occur more frequently in residents who have greater functional impairment.

Bacteriuria in elderly institutionalized men.

Over a two-year period we obtained monthly urine samples from all noncatheterized male residents on two geriatric wards to determine the occurrence and optimal management of bacteriuria in this population. Among 88 men the prevalence of bacteriuria was 33 per cent, and the incidence was 45 infections per 100 patients per year. Outcomes after single-dose therapy for asymptomatic bacteriuria with 43 courses of trimethoprim/sulfamethoxazole and 23 of tobramycin included 15 cures, 40 relapses, and 11 treatment failures. Thirty-six residents who had a relapse or in whom single-dose therapy failed were randomly assigned to receive therapy to eradicate bacteriuria or to receive no therapy. All 20 residents who received no therapy remained bacteriuric. The 16 residents who received therapy had fewer months of bacteriuria after randomization, but at the end of the study only one remained free of bacteriuria. Mortality and infectious morbidity after randomization were similar in the two groups. These data suggest that asymptomatic bacteriuria is common in elderly institutionalized men and that therapy is neither necessary nor effective.

15. Canadian experience with patient care classification.

Patient care classification in Canada in the past has been largely dictated by insurance coverage and the fiscal policies of the individual provinces. In recent years, however, the Canadian Department of Health and Welfare has been promoting the development of a standard patient care classification based on assessment of client or patient needs in regard to the category, type, and level of care. Experimentation with the proposed classification system in several provinces confirms the need in long-term care to include assessment of nursing requirements, physical functioning, and psychosocial assets and liabilities, and points to the importance of using such a classification for planning and evaluating patient care as well as for administrative purposes.
