A growing body of research indicates that prevention offers the
promise of better ways to maintain health and extend life. In this
timely volume, Louise B. Russell shows that preventive measures are
not as simple as often depicted while many do improve health, they
are not without risk or cost, and in fact rarely reduce medical
expenditures. Each measure, she argues, must be evaluated
individually and in all its dimensions: health benefits, health
risks, and resource costs.To demonstrate the many factors involved
in evaluating preventive measures, Russell examines the policy
debates about smallpox and measles vaccination, screening and drug
therapy for hypertension, and exercise. She uses these case studies
to explain the methods of cost-effectivness analysis, showing how
the choice among health investments can be made a more rational
exercise. The volume concludes with a suggested framework for the
design of future cost-effectiveness evaluations. Policymakers in
and out of the health field will benefit from this lucid
examination of the potential of prevention for improving health and
changing the allocation of limited resources.
