Justifying prenatal screening and genetic amniocentesis programs by cost-effectiveness analyses: a re-evaluation

Abstract

A strength of cost-effectiveness analysis is the presentation of all relevant clinical options, variables, and outcomes and the placement of values on the outcomes. Despite success in many fields of health policy, cost-effectiveness analysts have failed to provide a complete evaluation of prenatal screening and genetic amniocentesis programs. Specifically, all published cost-effectiveness analyses of these programs at best only partially acknowledge the potential life of the aborted fetus. These incomplete evaluations not only violate some basic principles of cost-effectiveness analysis, they also produce conclusions that may be misleading. Ultimately, society must answer two basic questions regarding the use of cost-effectiveness to justify prenatal screening programs: Is cost-effectiveness analysis an appropriate tool for the evaluation of these programs? If so, then what are the outcomes of interest? This paper first shows that the current literature does not present a complete evaluation of these programs. The ramifications of this incomplete evaluation are presented from several perspectives. Finally, given the problems associated with the use of cost-effectiveness analysis, the article suggests that cost-effectiveness analysis is not yet an appropriate tool to justify prenatal screening or genetic amniocentesis programs.
