  1. Population Health Surveys at STC Prepared for: B.C. Research Data Centre Date: Nov. 15, 2000

  2. Why Health Information Matters • $80 billion a year on health care • How do we improve the health of the population • Why are some healthier than others • The most critical contributors to health are not health related -- social status, control over work, education (CPRN)

  7. Opportunities to improve health information • Health Information Roadmap: a four-year action plan to strengthen Canada’s health information system; • Creation of Canadian Community Health Survey (CCHS) • Person oriented database

  8. NPHS longitudinal sample of 17,276 households national and provincial level estimates CCHS cross-sectional sample of 130,00 respondents national, provincial and sub provincial level estimates NPHS and CCHS - A More Robust Survey Program

  9. The Canadian Community Health Survey • Objectives • Estimates at the community health region level • Flexibility to enhance and vary content to meet unique regional and provincial needs • regular data collection • timely data release

  10. Canadian Community Health Survey Cycles and Components

  11. Canadian Community Health Survey Design • 2000/2001 • Sample size -- 130,000, stratified by health region • Questionnaire content • 30 minutes for priority items • 10 minutes of optional items selected by health regions • standard socio-economic items • Estimates for health regions, provinces and Canada • 2001/2002 • Sample size -- 30,000 • Proposed focused study on mental health and well-being

  12. CCHS - Year 1 Survey Sample Frames • Area frame (computer-assisted personal interview) • 94,000 households from the LFS structure • 78,000 households with 1 person selected • 16,000 households with 2 persons selected • RDD frame (computer-assisted telephone interview) • 20,000 households with 1 person selected these figures will be boosted before going in the field

  21. Mental Health & Well-Being Objectives 1. Determine prevalence rates of selected mental disorders to study adequacy of health care; 2. Juxtapose access and utilisation of mental health services with respect to perceived needs; 3. Assess the disability associated with mental health problems to individuals and society.
