Tuberculosis surveillance practices in long-term care institutions.
OBJECTIVES: To identify the tuberculosis (TB) skin-testing practices of long-term care facilities for the elderly in Toronto, Ontario. DESIGN: A telephone survey using a 25-item questionnaire. SETTING: Twenty-nine nursing homes (NHs) and 26 Homes for the Aged (HFAs) in metropolitan Toronto. RESULTS: Thirty-one percent of facilities (17 of 55) had no formal tuberculin skin-testing program, including 52% of NHs (15 of 29) versus 8% of HFAs (2 of 26; P = 0.001). Ninety-two percent of HFAs (24 of 26), compared with 45% of NHs (13 of 29), obtained preadmission or admission skin-test status of residents (P = 0.0005). Annual testing was performed at 46% of HFAs (12 of 26) and 27% of NHs (8 of 29; P = 0.28). Of facilities that carried out any skin testing, 64% of HFAs (16 of 25) versus 32% of NHs (6 of 19) measured induration to establish test positivity (P = 0.068). Fifty-two percent of HFAs (13 of 25), compared with 21% of NHs (4 of 19), recorded the actual size of induration in the patient record (P = 0.085). Only 28% of HFAs (7 of 25) and 21% of NHs (4 of 19) correctly defined a positive tuberculin skin test. CONCLUSIONS: TB surveillance practices in long-term care institutions in Toronto are inadequate and often yield results that do not predict the risk of infection and cannot be used to investigate outbreaks. Tuberculin skin-testing practices were better at HFAs, which are subject to provincial legislation regarding TB surveillance, than at NHs, which are not subject to this legislation. Staff at HFAs and NHs require education regarding tuberculin skin-testing policies and procedures.

Do geriatric programs decrease long-term use of acute care beds?
OBJECTIVE: To determine whether the introduction of coordinated geriatric and discharge planning services at teaching and community hospitals in Toronto has changed the number of beds occupied by patients awaiting transfer to long-term care institutions. DESIGN: Retrospective review of social work records for the period 1985-1992. SETTING: Two tertiary and four primary acute care hospitals in Metropolitan Toronto. PARTICIPANTS: Hospitals were matched for location, acuity, and teaching affiliation. MAIN OUTCOME MEASURES: The numbers of beds occupied by patients awaiting transfer to nursing homes or chronic care hospitals were noted. RESULTS: In those teaching and community hospitals that had introduced coordinated geriatric and discharge planning services, there was a reduction in the percentage of beds occupied by patients awaiting long-term care placement (average-51%), whereas in hospitals without geriatric services, the percentage of beds occupied by patients awaiting long-term care placement increased (average + 25%) (P = .05 by Fisher's exact method, 95% confidence limit odds ratio 0, .9999). CONCLUSION: The introduction of coordinated geriatric and discharge planning services was associated with a decrease in the percentage of beds occupied by patients awaiting long-term care in both teaching and community hospitals.

Age as a determinant of cardiopulmonary resuscitation outcome in the coronary care unit.
OBJECTIVE: To determine whether age is associated with the outcome of cardiopulmonary resuscitation (CPR) in the coronary care unit (CCU). DESIGN: Retrospective chart review. SETTING: The coronary care units of two Canadian tertiary care teaching hospitals. PATIENTS: Two hundred sixty-four coronary care unit patients undergoing cardiopulmonary resuscitation between January 1, 1985 and June 30, 1992. RESULTS: There was no significant difference in survival to discharge after CPR between patients less than 70 years of age (17.0%) and patients 70 years of age and older (17.2%) (odds ratio = 0.99; 95% confidence interval = 0.46, 1.80). Patients 70 years of age and older who survived to discharge after CPR had significantly greater lengths of stay (28.1 vs 19.3 days, P = .008). CONCLUSIONS: Age was not associated with a difference in survival to discharge after CPR in the CCU, although a clinically significant difference could not be excluded because of limited power.

Acute urinary retention in men: a comparison of voiding and nonvoiding patients after prostatectomy.
Multiple parameters were examined preoperatively to determine if any could predict successful voiding after prostatectomy in male patients who present in acute urinary retention due to benign prostatic hypertrophy. A total of 50 men 50 to 85 years old (mean age 69.5 years) who presented with this clinical picture was investigated with multichannel urodynamic studies, and completed the American Urological Association (AUA) symptom score for benign prostatic hypertrophy preoperatively and postoperatively. All patients underwent prostatectomy. Mean retention volume was 1,172 cc (range 500 to 2,100). Mean preoperative and postoperative AUA symptom scores were 15.5 and 5.0, respectively. At 3 months postoperatively 45 patients (90%) were able to void without catheterization. At 16.6 months 5 patients still required clean intermittent catheterization to empty the bladder. Postoperatively, there was a statistically significant improvement in AUA symptom score, opening voiding pressure and peak flow rate. The AUA symptom score was not predictive of either impending acute retention or normal voiding after prostatectomy. In our patients no preoperative parameters were statistically different between those voiding and those on clean intermittent catheterization. However, poor sensation, large retention volumes, lack of instability and no voluntary detrusor contractions were more common in the nonvoiding men.

A randomized trial of a decisional aid for mental capacity assessments.
The objective of this study was to evaluate the clinical utility of a decisional aid for mental capacity assessments which was developed using a group judgment methodology. This was carried out by a randomized, controlled trial. The subjects comprised 64 University of Toronto psychiatry residents in postgraduate years 1 through 4. Residents were randomized to carry out mental capacity assessments on simulated cases with, or without, the use of the decisional aid. The main outcome measure was the extent of agreement between the mental capacity determinations of residents and those of experts. There was no difference between the intervention and control groups with respect to the overall mean level of agreement with experts (0.87 vs 0.86, p = 0.88; 95% confidence interval for the difference between the study groups, -0.07 to +0.08). A logistic regression analysis, which adjusted for imbalances between the groups, also revealed no difference between the groups in their agreement with experts. The mean time per competency assessment was significantly longer in the intervention group (19.1 vs 10.8 min; p < 0.001). It was concluded that the decisional aid did not improve the ability of the psychiatry residents to make mental capacity assessments on simulated cases. Despite relatively limited formal training, the psychiatry residents had a high level of agreement with experts.

Erythrocyte protoporphyrin levels in patients with Friedreich's and other ataxias.
Of 13 patients with Friedreich's ataxia (Type Ia) and 17 with type IIa recessive ataxias, all were found to have levels of "free erythrocyte protoporphyrin" (FEP) above the normal range. The rise in FEP in Friedreich's ataxia correlated well with the age of the individual and thus appears to be related to the course of the disease. Subjects with olivo-ponto-cerebellar atrophy, Charlevoix syndrome, Duchenne muscular dystrophy, and Parkinson's disease were also found to have significantly elevated FEP, although the distribution overlapped with the normal range. The finding of elevated FEP may indicate a relative heme deficiency in ataxia due to inhibition of ferrochelatase leading to a state of ineffective, persistent erythropoiesis. The possibility of a prostaglandin abnormality being related to this defect and to the pathogenesis of ataxia is considered.

Cluster deaths in long-term care institutions: an investigation of excess deaths in two Ontario institutions.
OBJECTIVE: To review clusters of deaths in two Ontario long-term care institutions and to establish whether common etiologic factors could be identified. METHOD: Retrospective review of the health care records of all residents who died to assess the events leading to death and the actions of the institutions and local coroners in response to the deaths. RESULTS: A respiratory infectious outbreak appeared to lead to many of the deaths in both institutions. Several deficiencies were identified with respect to charting practices, coroners' case investigations and institutional responses to the infectious outbreaks. No formal mechanisms were in place to assist in the early detection of cluster deaths in these institutions. CONCLUSIONS: Infectious outbreaks may be an important cause of cluster deaths in long-term care institutions. Standards should be developed for patient charting, coroners' investigations and for the prevention, identification and management of infectious outbreaks in such settings.
