Title: Implications of spillover effects within the family for medical cost-effectiveness analysis.

Journal: J Health Econ 24(4):751-73

Date: 2005 Jul

Abstract: Medical cost-effectiveness analyses traditionally treat patients as isolated individuals and neglect the effects of improvement in patients' health on the welfare of their family members. We use a model based on a family utility function with altruistic linkages to show that there can be direct and indirect effects on the welfare of all family members. We focus specially on a model of how the spillover effects to the spouse in a two-person family might affect choice of treatments for prostate cancer. We then test the predictions of this model by analyzing treatment choices of prostate cancer patients using the linked SEER-Medicare database. We find that our results are consistent with the model's predictions. We conclude that cost-effectiveness analyses may better reflect the full costs and benefits of medical interventions if they incorporate these family effects. However, concerns about equity present a dilemma for the practice of CEA from the societal perspective.
