Self-Care for Older People (SCOPE): a cluster randomized controlled trial of self-care training and health outcomes in low-income elderly in Singapore.



Population aging is associated with a higher prevalence of chronic health conditions. Previous studies have shown that older persons, specifically those with chronic conditions, often lack sufficient knowledge about their condition and thus frequently have poor self-care skills. Efforts to increase general health screenings and improve access to chronic condition management resources are hampered by a lack of disease and health awareness. Self-Care for Older People (SCOPE) study, a cluster randomized controlled trial in Singapore, was designed to evaluate the impact of a self-care program for chronic disease awareness and management of specific health measures and quality of life of older people over eighteen months. SCOPE provided self-care education targeted at older people with low income and low education in order to improve health-related knowledge. A total of 378 low-income older people with no or minimal disability, defined as having difficulty in one or more activities of daily living (ADL), were recruited from senior activity centers. The measurements taken included self-reported health conditions, health and disease knowledge questions, and biomarkers (HbA1c, blood pressure, peak expiratory flow, lipid panel, albumin, and creatinine). SCOPE was also designed to provide information for policy makers on chronic disease burden and healthcare facility utilization among community-dwelling older adults.

My research relates to clinical practice improvement - from the development of clinical policies to their implementation in real world clinical settings. Most recently my major content focus has been cerebrovascular disease. Other major clinical areas in which I work include the range of disabling neurological conditions, cardiovascular disease, and cancer prevention.
Notable features of my work are: (1) reliance on analytic strategies such as meta-analysis, simulation, decision analysis and cost-effectiveness analysis; (2) a balancing of methodological rigor the needs of medical professionals; and (3) dependence on interdisciplinary groups of experts.
This approach is best illustrated by the Stroke Prevention Patient Outcome Research Team (PORT), for which I served as principal investigator. Funded by the AHCPR, the PORT involved 35 investigators at 13 institutions. The Stroke PORT has been highly productive and has led to a stroke prevention project funded as a public/private partnership by the AHCPR and DuPont Pharma, the Managing Anticoagulation Services Trial (MAST). MAST is a practice improvement trial in 6 managed care organizations, focussing on optimizing anticoagulation for individuals with atrial fibrillation.
I serve as consultant in the general area of analytic strategies for clinical policy development, as well as for specific projects related to stroke (e.g., acute stroke treatment, management of atrial fibrillation, and use of carotid endarterectomy.) I have worked with AHCPR (now AHRQ), ACP, AHA, AAN, Robert Wood Johnson Foundation, NSA, WHO, and several pharmaceutical companies.
