- 6. 6 Maintain Neutral Evidence-Based Position This project is about getting the evidence right – if there is anything we are missing – let us know. If we have anything wrong let us know and provide the evidence demonstrating this. We expect people will sometimes interpret the evidence differently. That is ok, but we do want to make sure we have the evidence right.
- 7. 7 Aging Population: What’s the Issue • The aged are small part of population • Population has been aging for years: we know what to expect • Real issue: we are doing too much and spending too much
- 8. 8 More to Health than Healthcare • How many years would you add to life expectancy if wipe out cancer? • How many years would you add if gave inner core Winnipeggers the life expectancy of affluent suburbanites? Manton has estimated that if every child could be given a pill at birth – which would eliminate every type of cancer (and the heroic assumption is made that people don’t die earlier of something else), this would add 3.8 years to males’ life expectancy and 2.6 years to female’s. Estimates of the gains to life expectancy from the elimination of the other major disease killer, coronary heart disease, are similarly modest (estimated to be a little over 3 years by Tsevat).

Hinweis der Redaktion
- More critical looks must be taken at PSA testing and mammography screening Archives of Internal Medicine recently argued “less is more” There should be no imaging tests for low back pain unless specific symptoms, no annual ECGs or cardiac screening tests for low risk patients with no symptoms of heart disease
- Compared to the 3-4 years of potential gain for wiping out cancer – we find males who live down town have a life expectancy 14 years shorter than males who live in the affluent suburbs down South Pembina highway; and women 16 years And there is evidence that small income increases can produce health benefits: the province of Manitoba introduced the prenatal benefit – a maximum of $81/a month available during pregnancy for those with a net income under $32,000. An uptake of this benefit was associated with a reduction in low birthweight births, reduction in preterm births and an increase in breast feeding initiation (Manitoba Centre for Health Policy report).
