Fidelity and Recovery-Orientation in Assertive Community Treatment

There has been increasing commentary about the degree to which Assertive Community Treatment (ACT) teams provide recovery-oriented services, often centered around the question of the use of coercion. The present study was designed to contribute to this discussion through an examination of recovery-oriented service provision and ACT fidelity among 67 teams in the province of Ontario, Canada. The findings indicated a moderate to high degree of recovery orientation in service provision, with no significant relationship between ACT fidelity and consumer and family/key support ratings of recovery orientation. A significant relationship was found, however, between the ‘nature of services’ domain of the Dartmouth Assertive Community Treatment Scale (DACTS) and ratings of recovery orientation provided by staff and ACT coordinators. These findings extend the existing dialogue regarding the evaluation of ACT intervention process factors and indicate that current measures of fidelity may not be adequately addressing dimensions of recovery-oriented service provision.     

Testing for heterogeneity among the components of a binary composite outcome in a clinical trial

Background  

Investigators designing clinical trials often use composite outcomes to overcome many statistical issues. Trialists want to maximize power to show a statistically significant treatment effect and avoid inflation of Type I error rate due to evaluation of multiple individual clinical outcomes. However, if the treatment effect is not similar among the components of this composite outcome, we are left not knowing how to interpret the treatment effect on the composite itself. Given significant heterogeneity among these components, a composite outcome may be judged as being invalid or un-interpretable for estimation of the treatment effect. This paper compares the power of different tests to detect heterogeneity of treatment effect across components of a composite binary outcome.     

Effect of smoking on lung function,respiratory symptoms and respiratory diseases amongst HIV-positive subjects: a cross-sectional study

Background  

Smoking prevalence in human immunodeficiency virus (HIV) positive subjects is about three times of that in the general population. However, whether the extremely high smoking prevalence in HIV-positive subjects affects their lung function is unclear, particularly whether smoking decreases lung function more in HIV-positive subjects, compared to the general population. We conducted this study to determine the association between smoking and lung function, respiratory symptoms and diseases amongst HIV-positive subjects.     

Cardiovascular Health Awareness Program (CHAP): a community cluster-randomised trial among elderly Canadians

OBJECTIVE: High blood pressure is an important and modifiable cardiovascular disease risk factor that remains under-detected and under-treated. Community-level interventions that address high blood pressure and other modifiable risk factors are a promising strategy to improve cardiovascular health in populations. The present study is a community cluster-randomised trial testing the effectiveness of CHAP (Cardiovascular Health Awareness Program) on the cardiovascular health of older adults. METHODS: Thirty-nine mid-sized communities in Ontario, Canada were stratified by geographic location and size of the population aged >or=65 years and randomly allocated to receive CHAP or no intervention. In CHAP communities, residents aged >or=65 years were invited to attend cardiovascular risk assessment sessions held in pharmacies over 10 weeks in Fall, 2006. Sessions included blood pressure measurement and feedback to family physicians. Trained volunteers delivered the program with support from pharmacists, community nurses and local organisations. RESULTS: The primary outcome measure is the relative change in the mean annual rate of hospital admission for acute myocardial infarction, congestive heart failure and stroke (composite end-point) among residents aged >or=65 years in intervention and control communities, using routinely collected, population-based administrative health data. CONCLUSION: This paper highlights considerations in design, implementation and evaluation of a large-scale, community-wide cardiovascular health promotion initiative.     

Hip fracture prevention strategies in long-term care: a survey of Canadian physicians' opinions

OBJECTIVE

To garner Canadian physicians’ opinions on strategies to reduce hip fractures in long-term care (LTC) facilities, focusing on secondary prevention.

DESIGN

A cross-sectional survey using a mailed, self-administered, written questionnaire.

SETTING

Canada.

PARTICIPANTS

Family physician members of the Ontario Long-Term Care Association (n = 165) and all actively practising geriatricians registered in the Canadian Medical Directory (n = 81).

MAIN OUTCOME MEASURES

The strength of recommendations for fracture-reduction strategies in LTC and barriers to implementing these strategies.

RESULTS

Of the 246 physicians sent the questionnaire, 25 declined study materials and were excluded. Of the 221 remaining, 120 responded for a response rate of 54%. About two-thirds of respondents were family physicians (78 of 120) and the rest were mostly geriatricians. Most respondents strongly recommended the following secondary prevention strategies for use in LTC after hip fracture: calcium, vitamin D, oral aminobisphosphonates, physical therapy, and environmental modification (such as handrails). Most respondents either did not recommend or recommended limited use of etidronate, intravenous bisphosphonates, calcitonin, raloxifene, testosterone (for hypogonadal men), and teriparatide. Postmenopausal hormone therapy was discouraged or not recommended by most respondents. Support was mixed for the use of hip protectors, B vitamins, and folate. Barriers to implementation identified by most respondents included a lack of strong evidence of hip fracture reduction (for B vitamins and folate, cyclic etidronate, and testosterone), side effects (for postmenopausal hormone therapy), poor compliance (for hip protectors), and expense (for intravenous bisphosphonates and teriparatide). Some respondents cited side effects or poor compliance as barriers to using calcium and potent oral bisphosphonates.

CONCLUSION

Canadian physicians favour the use of calcium, vitamin D, potent oral bisphosphonates, physical therapy, and evironmental modifications for LTC residents after hip fracture. Further study at the clinical and administrative levels is required to find ways to overcome the specific barriers to implementation and effectiveness of these interventions.

A shared care model pilot for palliative home care in a rural area: impact on symptoms, distress, and place of death

Context

Shared care models integrating family physician services with interdisciplinary palliative care specialist teams are critical to improve access to quality palliative home care and address multiple domains of end-of-life issues and needs.

Objectives

To examine the impact of a shared care pilot program on the primary outcomes of symptom severity and emotional distress (patient and family separately) over time and, secondarily, the concordance between patient preferences and place of death.

Methods

An inception cohort of patients (n = 95) with advanced, progressive disease, expected to die within six months, were recruited from three rural family physician group practices (21 physicians) and followed prospectively until death or pilot end. Serial measurement of symptoms, emotional distress (patient and family), and preferences for place of death was performed, with analysis of changes in distress outcomes assessed using t-tests and general linear models.

Results

Symptoms trended toward improvement, with a significant reduction in anxiety from baseline to 14 days noted. Symptom and emotional distress were maintained below high severity (7-10), and a high rate of home death compared with population norms was observed.

Conclusion

Future controlled studies are needed to examine outcomes for shared care models with comparison groups. Shared care models build on family physician capacity and as such are promising in the development of palliative home care programs to improve access to quality palliative home care and foster health system integration.
