The Economics of Age-Related Macular Degeneration
Abstract
The Patient Protection and Affordable Care Act of 2010 funded the Patient-Centered Outcomes Research Institute to promote the use of comparative effectiveness analysis and cost-effectiveness analysis in the Unites States. There are four healthcare economic analysis variants: (1) cost-minimization analysis, (2) cost-benefit analysis, (3) cost-effectiveness analysis, and (4) cost-utility analysis. Cost-utility analysis, which uses the outcome $/QALY (dollars expended per QALY gained) is the most sophisticated. The comparative effectiveness, or human value gain conferred by an intervention can be objectively measured using the QALY (quality-adjusted life year). Most commonly, only the direct ophthalmic medical costs of therapy for neovascular age-related macular degeneration (AMD) are addressed in the literature. Societal costs are more desirable. Intravitreal ranibizumab therapy versus no therapy for subfoveal neovascular AMD confers a 15.9–28.2% value gain (improvement in the quality of life), intravitreal bevacizumab with intraocular brachytherapy a 22.4% value gain, photodynamic therapy an 8.1% value gain, intravitreal pegaptanib a 5.9% value gain, and laser therapy a 4.4% value gain. Extrafoveal laser photocoagulation confers an 8.1% value gain over no therapy.
