cost-effectiveness & resource allocation

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?

Cost-Effectiveness Analysis

(aka…..value for money)

Costs

Costs include:

Care by health professionalsLabs and X-RaysHospital/facility chargesMedicationsOther 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

0 1

Dead Perfecthealth

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 = QALYsSaves 100 x 0.8 x 50 = 4000 Lives Improves 10,000 x 0.1 x 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…

Cost Life Expectancy HRQLQALYS

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?

Condition/Treatment Cost per QALY

Treatment for Erectile Dysfunction $6,400/QALY

*Physician Counseling for Smoking $7,200/QALY

Total Hip Replacement $9,900/QALY

*Outreach for Flu and Pneumonia $13,000/QALY

Treatment of Major Depression $20,000/QALY

Gastric Bypass Surgery $20,000/QALY

Treatment for Osteoporosis $38,000/QALY

*Screening For Colon Cancer $40,000/QALY

Implantable Cardioverter Defibrillator $75,000/QALY

Lung-Volume Reduction Surgery $98,000/QALY

Tight Control of Diabetes $154,000/QALY

*Treating Elevated Cholesterol ( + 1 risk factor) $200,000/QALY

Resuscitation After Cardiac Arrest $270,000/QALY

Left Ventricular Assist Device $900,000/QALY

COST/QALY: Selected Medicare Services

For consideration…

Should prevention be thought of differently from other types of health care?
