RESUMEN
OBJECTIVE: To test Comprehensive Geriatric Assessment (CGA) as an adjunct to usual care. DESIGN: A randomized controlled trial with 3, 6, and 12 months follow-up. SETTING: Rural communities. PATIENTS: A total of 182 of 265 frail older patients (52 refused, 2 withdrawn, 27 ineligible, 2 deaths) referred by family practitioners with allocation to intervention (n = 95) or usual care (n = 87). INTERVENTION: Three-month implementation of CGA recommendations by a Mobile Geriatric Assessment Team (MGAT) with follow-up assessments at 3, 6, and 12 months. Geriatric nurse assessors, blinded to group assignment, performed each assessment. MAIN OUTCOME MEASURE: Goal Attainment Scaling (GAS). RESULTS: Baseline characteristics were comparable between groups. At 3 months, the intervention group was more likely to attain their goals (GAS total: chi = 46.4 +/- 5.9; GAS outcome chi = 48.0 +/- 6.6) compared with controls (total: chi = 38.7 +/- 4.1; outcome chi = 40.8 +/- 5.6) (P < .001). Standard assessments of function (Barthel index, instrumental activities of daily living), cognition (Mini-Mental State Examination), and quality of life (modified Spitzer quality of life index) showed no difference over 12 months. No difference in survival (intervention: chi = 320 days, SE = 6; control: chi = 294 days, SE = 6; P = .257) or time to institutionalization (intervention: 340 days, SE = 9; control: 342 days, SE = 8; log rank = 0.661; P = .416) were observed. CONCLUSIONS: A MGAT can target rural dwelling, frail older persons, perform in-home CGA, and develop an intervention strategy. Although the intervention did not prolong life or delay institutionalization, clinically important benefits were observed.

BACKGROUND: By 2016, the proportion of Canadians older than 65 years of age will increase to 16%, and there will be an increase in the absolute number of cases of cardiovascular disease in older Canadians. The Canadian Heart Health Surveys database provides information about this population upon which health policy related to cardiovascular disease can be based. This paper presents for the first time population-based data on the risk factors for cardiovascular disease in older Canadians. METHODS: Canadians from all 10 provinces participated in surveys of cardiovascular risk factors; health insurance registries were used as sampling frames. In each province, probability samples of 2200 adults 18 to 74 years old not living in institutions, on reserves or in military camps were asked to participate in interviews and to undergo testing at clinics for major risk factors for cardiovascular disease. RESULTS: A total of 2739 men (response rate 70%) and 2617 women (response rate 66%) aged 55 to 74 years participated in the survey and also provided follow-up clinical measurements at the clinic. Overall, 52% of participants were hypertensive, 26% had isolated systolic hypertension, and 30% had a total blood cholesterol level of 6.2 mmol/L or greater. Rates of current smoking were lower in women than men (17% v. 22%). Overall, 87% of men and 78% of women who were current smokers smoked at least 10 cigarettes per day. Only slightly more than half of participants exercised at least once a week for at least 15 minutes, and almost half had a body mass index of 27 or greater. In only 4% was no major risk factor for cardiovascular disease detected. INTERPRETATION: Significant numbers of older Canadians have one or more major risk factors for cardiovascular disease. Many of these risk factors are amenable to modification.

BACKGROUND: Cardiovascular disease is the leading cause of death and disability in older people, who account for an increasing proportion of Canada's population. Knowledge and awareness of risk factors is essential for changes in behaviour, yet little is known about these issues in older people. The Canadian Heart Health Surveys database provides a unique resource to examine knowledge and awareness of cardiovascular risk factors in older Canadians. METHODS: This descriptive cross-sectional study used data from the Canadian provinces' Heart Health Surveys, for the years 1986 to 1992. Sampling within each province consisted of stratified, 2-stage, replicated probability samples; 4976 people 55 to 74 years of age were included in the present analysis. Knowledge and awareness of cardiovascular risk factors was determined from the survey question "Can you tell me what are the major causes of heart disease or heart problems?" Blood pressure was measured during a home visit; anthropometric and blood measurements were obtained during a clinic visit. Cardiovascular health status was determined by self-reporting. RESULTS: Smoking and stress or worry were mentioned as major causes of heart disease by the greatest proportion of participants (41% and 44% respectively); hypertension was mentioned by only 16%. Men and women did not differ in their awareness of high blood cholesterol (cited by 23% of participants), smoking (41%), excess weight (30%) or lack of exercise (28%) as causes of heart disease. A greater proportion of women than men were aware of hypertension (19% v. 12%) and heredity (31% v. 17%) as major causes of heart disease. Awareness of risk factors was consistently lower in the older age group (65-74 v. 55-64 years). Among women, there was greater awareness of the respective risk factors as causes of heart disease among those who were smokers (60% v. 35% of nonsmokers), those who had a body mass index (BMI) of 25 or greater (38% v. 24% of those with a BMI less than 25) and those who were hypertensive (22% v. 17% of those without hypertension). Those who had experienced a heart attack had greater awareness of the major causes of heart disease than those who had not; this pattern was stronger among women than among men. Of those in whom elevated cholesterol level was identified during the course of the study, 62% of men and 67% of women were unaware of their cholesterol status. Of those in whom high blood pressure was diagnosed, 43% of men and 33% of women were unaware of their hypertensive status. INTERPRETATION: Awareness of the major causes of cardiovascular disease is low among older Canadians, especially among men and in those 65 to 74 years of age.

Goal Attainment Scaling (GAS), an individualized measurement approach, is particularly attractive for the evaluation and care planning of frail elders, who often experience multiple, complex problems. Some service providers find GAS too unwieldy for routine use. A modified version of GAS that uses a standardized menu of goals and attainment levels has been developed by the Geriatric Assessment and Rehabilitation Unit of a regional referral hospital in Nova Scotia, Canada. This article reviews the development, implementation, benefits, and challenges of the standardized menu, as well as the results of a retrospective descriptive study of its measurement properties. The standardized menu appears to be a feasible, valid, and responsive alternative to traditional GAS, while retaining much of its individualized nature.

PURPOSE: To assess stress in medical students, residents, and graduate science students at four Canadian schools of medicine. METHOD: Four schools with different curricula in three different parts of Canada participated in the study: the University of Calgary Faculty of Medicine, the University of Alberta Faculty of Medicine, the Dalhousie University Faculty of Medicine, and the McMaster University Faculty of Health Sciences. All the medical students, residents, and graduate science students at each school were surveyed in 1994-95. The three instruments used were the University of Calgary Stress Questionnaire, the Social Readjustment Rating Scale (SRRS), and the Symptom Checklist-90. Demographic data were compared across all four schools. Analysis of variance was calculated for all test-item scores, utilizing a four (school) by three (program) by two (gender) design, which were all between subject factors. Significant main effects were followed up by using planned comparisons (Newman-Keuls, with a probability level of p < .05). Significant interaction effects were followed up by using an analysis of simple effects. RESULTS: A total of 1,681 questionnaires were returned as follows: 621 of 1,304 (48%) from the medical students, 645 of 1,495 (43%) from the residents, and 415 of 829 (50%) from the graduate science students. There were significant differences between the three groups in the natures and degrees of stress, with the graduate students reporting higher levels of stress. There were significant gender differences as well, with the women reporting higher levels of stress. Overall, stress levels were found to be mild, based on the University of Calgary Stress Questionnaire and the SRRS. CONCLUSION: This study suggests that medical students and residents experience stress at levels that appear acceptable, but ongoing monitoring and the provision of appropriate support systems will continue to be important.

Despite their limitations, mental status tests and self/proxy reports of instrumental activities of daily living (IADL) are often used to predict functional competence. In contrast, the Assessment of Motor and Process Skills (AMPS) is a direct observational assessment of IADL competence. Sixty-four community-dwelling elderly (20 Alzheimer's disease [AD] patients and 44 nondemented) were assessed with the AMPS, the Mini-Mental State Examination (MMSE), and the Older Americans Resources and Services (OARS)-IADL. Performance on all three assessments was significantly lower for the AD sample. The MMSE did not correlate significantly with the AMPS motor ability measures but it correlated modestly with the AMPS process ability measures. The OARS-IADL correlated significantly with the AMPS motor ability measure for the nondemented sample alone. Although mental status and self/proxy assessments provide some insight into individuals' IADL competence, direct observation of IADL task performance provides additional information regarding the subtle process and motor skills changes that occur in progressive dementing conditions.
