Cost-Effectiveness &Resource Allocation Wisconsin Public Health and Health Policy Institute May 26, 2005
For consideration… • How should the health policy community balance competing priorities of: • Maximizing health • Minimizing budget • Should prevention be thought of differently from other types of health care? • What is the role for the public in this discussion?
Infant Mortality Rates Infant Mortality Rates (per 1,000 Live Births) By OECD Country in 2000
Reasons for Changes in Medical Care Spending 1987-2000. Thorpe, K et al, . Health Affairs, 2004 Percent change in spending attributable to: Increase cost/ Rise in treated Increased treated case prevalence population Disease and $s(in billions)
Cost-Effectiveness Analysis (aka…..value for money)
Costs Costs include: Care by health professionals Labs and X-Rays Hospital/facility charges Medications Other expenses related to illness
Effectiveness in Cost-Effectiveness Analysis • An effective treatment or intervention does one or both of the following: • Increase how long people live • Improve or maintain how well people feel
Quality-adjusted life years:A measure of effectiveness (Life expectancy) (quality of life)=QALYs
Health-related Quality of Life 1 0 Dead Perfect health
Calculations:Quality-Adjusted Life Years If, HRQL= 0.7 And, A treatment gives 10 extra years of life (@ 0.7 per year) Then…. People receiving the treatment gain Seven Quality-Adjusted Life Years (7 QALYs)
A QALY is a QALY is a QALY #People HRQL LE = QALYs Saves 100 x 0.8 x50 = 4000 Lives Improves 10,000 x0.1x 4 = 4000 HRQL
The cost-effectiveness of one thing compared to another… Cost treatment A – Cost treatment B Effectiveness treatment A – Effectiveness treatment B = COST per QALY
For example… CostLife ExpectancyHRQLQALYS Group A$80,000 2 Years X .6 =1.2 Group B$ 4,000 1 Year X .8 = 0.8 Cost-effectiveness: $80,000 - $4,000 = $76,000 =$190,000/QALY 1.2 – 0.8 0.4
What’s a “Good” Buy? “Expensive” more than 100K/QALY “Reasonable” 50K/QALY “Very Efficient” less than 25K/QALY
Cost-Effectiveness AnalysisSome Questions….. • Should “life-saving” be placed on the same mathematical scale as “quality improving”? • Is it appropriate to consider cost per QALY when diseases are immediately life-threatening? • How would we justify discriminating against people who have diseases that are “inefficient” to treat? • Should QALYs count the same regardless of whether they go to young or old? • The not so sick, versus the very sick? • When prevention is as “cost-effective” as cure, which gets priority?
