    5. 5 Life Expectancy at birth Many factors go into improving health outcomes: Pease and stable ecosystem, food and shelter, education, sustainable resources, child development, working conditions, income and social status, health services, social supports Hence, life expectancy in Canada has steadily improved and continues to rise.

    6. 6 Quality of Life Not only about how long we live, it’s about maximizing the number of healthy years we live. Many ways to monitor: Well-being Ability to Function Healthy life expectancy Historically, the significant improvement in life and quality of life expectations are due to: improved nutrition, more broad availability of adequate housing, smaller families, better sanitation and clean water, advent of pasteurization and immunization Not only about how long we live, it’s about maximizing the number of healthy years we live.

    12. 12 Cataract surgery - not all positive outcomes Cataract surgery. Distribution of post-operative changes in Visual Function Assessment score. Data were missing for 3% of patients. Interpretation: Not all cataract surgeries produced positive patient outcomes; in fact the result is worse vision for approximately 26%. This study questions the appropriateness for surgery indications as the threshold for cataract surgery in this region is very low (the mean VFA was 79 in this study compared to a range of 64-77 reported elsewhere). Other international published studies of patients who received cataract surgery show worse outcomes ranging from 5.5% to 36.7%. A few studies also have shown a significant change quality of life measures – both positive and negative. Measuring patient outcomes using the HRQOL and VFA are feasible, at reasonable cost and could be included into an accountability framework for health services. Red Flags: Critics may argue over the HRQOL used ie. methodology debate rather than outcome debate. Also the bias introduced by the lack of surgeon participation in the second study should only bias in the favour of potentially more negative HRQOL changes being identified. Cataract surgery.

    13. 13 Getting a New Heart? Cardiac transplantation showed a survival benefit only for patients with a predicted high risk of dying on the waiting list - (Deng, De Meester, Smits, Heinecke and Scheld on behalf of the Comparative Outcome and Clinical Profiles in Transplantation (COCPIT) Study Group, BMJ 2000;321:540-5) -Transplantation only improved survival of medium and high-risk patients compared with medical therapy - (Lim et al. Journal of Heart and Lung Transplant 2005;24(8):983-989) -A survival benefit is anticipated only for severely ill patients (Krakauer, Lin and Bailey Journal of Heart and Lung Transplantation 2005;24(6):680-689).

    27. 27 Addressing The Determinants Partner- Who can we work with, to do it better together? Advocate- What needs to be done at policy legislative level? Cheerlead- Encouraging and not getting in the way. Enable- What we do directly to change the determinants Mitigate- Picking up some of the pieces, so it isn’t worse

    31. 31 A problem? Breakdown of community and social supports Mental wellbeing Vision and focus on the public good? 55% of adults inactive 36% of adults overweight 23% of adults obese Tobacco-use remains highest health risk 2,700 babies with FASD every year 11% of youth that drink =frequent binge drinking Etc. Despite the efforts and accomplishments of the many programs that are provided across Canada, the following data raise serious concerns about the future health of Canadians. 55% of Canadians are not physically active or moderately active (CCHS, 2004); 36% of adult Canadians are overweight and 23% are obese (CCHS, 2004); The eating habits of adult Canadians fall substantially short of standards for good nutrition as recommended by Canada’s Food Guide. Tobacco-use remains the risk factor, which contributes the most towards the burden of disease in Canada; The incidence of FASD is about 9 per 1,000 live births (ref. Chudley et al. in CMAJ March 1, 2005) or 2,700 babies each year; and 11% of school-aged youth who drink, report frequent binge drinking (2 to 3 times per month).. NOTES: Only 33.4 % of Canadians consume the recommended number of servings of fruits and vegetables per day (CCHS, 2004).Despite the efforts and accomplishments of the many programs that are provided across Canada, the following data raise serious concerns about the future health of Canadians. 55% of Canadians are not physically active or moderately active (CCHS, 2004); 36% of adult Canadians are overweight and 23% are obese (CCHS, 2004); The eating habits of adult Canadians fall substantially short of standards for good nutrition as recommended by Canada’s Food Guide.

    41. 41 Estimates of Health Impacts in Canada During a Pandemic 11,000 to 58,000 deaths 34,000 to 138,000 hospitalizations 2 to 5 million outpatients (Most deaths due to secondary infections, e.g. pneumonia) Economic costs: health care: $330 million to $1.4 billion societal (lost productivity): $5 to $38 billion We cannot predict the impact of the next pandemic; impacts of previous pandemics have been very different. However, simple statistical models that project estimates based on a set of assumptions are helpful for planning purposes. The estimated economic impact of a pandemic influenza in Canada would be $10 to 24 billion ($5-38), excluding disruptions to commerce and society. The economic impact includes direct medical costs associated with hospitalizations, outpatient visits and drug purchases. The principal indirect cost was lost productivity i.e time off work, economic cost of a death.

    42. 42 Pandemic Canada 1918-19 By today’s population: 150-160,000 deaths…but General better health and nutrition Antibiotics for secondary infections Vaccines and anti-virals Not post WWI – Magnified in trenches & mass population movements Not multiple underlying infections Good health care and better understanding However, many developing countries similar

    43. 43 Just in Case Medicine? 1 Antivirals for Prophylaxis- lack of studies to demonstrate effectiveness Risk of earlier resistance? May not be effective against pandemic virus Side effects Ability to deliver? Who gets and why?

    44. 44 Just in Case Medicine? 2 N95 vs surgical masks (possible exceptions-eg high risk procedure., cull infected birds) Droplet Spread (practical difference between demonstrating can find virus and that it actually causes infection by other means) N95 proper fit needed and difficult to wear long term May actually increase risk in wrong setting Supply and access issues

    46. 46 CO2 in at least the past 650,000 years The human influence on the climate system is primarily through the effect of greenhouse gas and aerosol emissions on the make-up of the atmosphere and its role in the climate system. Atmospheric concentrations of greenhouse gases, which insulate the earth from heat loss to space, have been in remarkable balance over the past millennium. This is illustrated by the measurements of CO2 concentrations extracted from fossilized air in polar ice sheets, as shown, but also applies to other key greenhouse gases. In fact, concentrations of carbon dioxide (the most important of these greenhouse gases) appear to have never exceeded 300 ppm during at least the last 650,000 years. However, during the past century, its concentrations have increased by 31%. Other gases have also increased dramatically. There is clear evidence that these increases are due to human emissions, primarily from combustion of fossil fuels for energy purposes and due to deforestation.

There are significant concerns about the quality of the historical data used for this study. However, experts suggest trends are too large to be explained by data problems.

    48. 48 The above trends are primarily due to losses associated with weather disasters. However, the most recent pentad includes ~$100B for the Kobe earthquake disaster. While the industry suggests that much of the increase can be attributed to demographic factors, it is convinced that a significant factor is more frequent extremes. The climatological data for extreme weather events, particularly those associated with multiple climate factors, are inadequate to properly analyze long term trends for all events.
