RESUMO
PURPOSE: To describe an economic (Ec) model for estimating the impact of screening and treatment for retinopathy of prematurity (ROP). DESIGN: EcROP is a cost-effectiveness, cost-utility, and cost-benefit analysis. METHODS: We surveyed caregivers of 52 children at schools for the blind or pediatric eye clinics in Atlanta, Georgia and 43 in Mexico City. A decision analytic model with sensitivity analysis determined the incremental cost-effectiveness (primary outcome) and incremental monetary benefit (secondary outcome) of an ideal (100% screening) national ROP program as compared to estimates of current practice. Direct costs included screening and treatment expenditures. Indirect costs estimated lost productivity of caretaker(s) and blind individuals as determined by face-to-face surveys. Utility and effectiveness were measured in quality-adjusted life years and benefit in US dollars. EcROP includes a sensitivity analysis to assesses the incremental cost-effectiveness and societal impact of ROP screening and treatment within a country or economic region. Estimates are based on evidence-based clinical data and region-specific economic data acquired from direct field survey. RESULTS: In both Mexico and the United States, an ideal national ROP screening and treatment program was highly cost-saving. The incremental net benefit of an ideal ROP program over current practice is $5556 per child ($206 574 333 annually) and $3628 per child ($205 906 959 annually) in Mexico and the United States, respectively. CONCLUSION: EcROP demonstrates that ROP screening and treatment is highly beneficial for quality of life, cost saving, and cost-effectiveness in the United States and Mexico. EcROP can be applied to any country or region to provide data for informed allocation of limited health care resources.

PURPOSE: To determine the cost-effectiveness of laser treatment for retinopathy of prematurity (ROP) in Lima, Peru. DESIGN: A cost-of-illness study (in US dollars) to determine the direct cost of treatment, the indirect lifetime cost of blindness, and the quality-adjusted life years. METHODS: The direct cost of ROP-related treatment was determined by reviewing data retrospectively from a social security sector hospital. The indirect cost was determined using national economic data of Peru published by the Central Information Agency (CIA), including the per capita gross domestic product, the sex-adjusted income distribution, and years spent in the work force. Indirect costs per child that were avoided by treatment were calculated using the known natural history of ROP vs evidence-based treatment. RESULTS: For ROP-related neonatal blindness in Peru, we estimate the total indirect cost saving at $197,753 per child and the direct cost of laser treatment at $2496 per child. The societal lifetime cost saving per child is estimated at $195,257. The mean annual income per educated adult in Peru is $8000 and treating 1 child is equivalent to employing 24 educated Peruvians per year. The generational cost savings for society is approximately $516 million, or the equivalent of 64,500 educated Peruvian work years. CONCLUSIONS: The societal burden of blindness far exceeds the costs of treatment per child. Proper screening and treatment of ROP prevents blindness and leads to substantial cost savings for society. Public health policy in Peru and other middle-income countries should consider financial impact when allocating healthcare resources.
