Cost-effectiveness of retinal detachment repair

Abstract

Objective: To evaluate costs and treatment benefits of rhegmatogenous retinal detachment (RD) repair.

Design: A Markov model of cost-effectiveness and utility.

Participants: There were no participants.

Methods: Published clinical trials (index studies) of pneumatic retinopexy (PR), scleral buckling (SB), pars plana vitrectomy (PPV), and laser prophylaxis were used to quantitate surgical management and visual benefits. Markov analysis, with data from the Center of Medicare and Medicaid Services, was used to calculate the adjusted costs of primary repair by each modality in a hospital-based and ambulatory surgery center (ASC) setting.

Main outcome measures: Lines of visual acuity (VA) saved, cost of therapy, adjusted cost of therapy, cost per line saved, cost per line-year saved, and cost per quality-adjusted life years (QALY) saved.

Results: In the facility, hospital surgery setting, weighted cost for PR ranged from $3726 to $5901 depending on estimated success rate of primary repair. Weighted cost was $6770 for SB, $7940 for PPV, and $1955 for laser prophylaxis. The dollars per line saved ranged from $217 to $1346 depending on the procedure. Dollars per line-year saved ranged from $11 to $67. Dollars per QALY saved ranged from $362 to $2243. In the nonfacility, ASC surgery setting, weighted cost for PR ranged from $1961 to $3565 depending on the success rate of primary repair. The weighted costs for SB, PPV, and laser prophylaxis were $4873, $5793, and $1255, respectively. Dollars per line saved ranged from $139 to $982. The dollars per line-year saved ranged from $7 to $49, and the dollars per QALY saved ranged from $232 to $1637.

Conclusions: Treatment and prevention of RD are extremely cost-effective when compared with other treatment of other retinal diseases regardless of treatment modality. Retinal detachment treatment costs did not vary widely, suggesting that providers can tailor patient treatments solely on the basis of optimizing anticipated results because there were no overriding differences in financial impact.
