Abstract
To assess the cost-effectiveness of primary noncomplex rhegmatogenous retinal detachment (RRD) repair, comparing 3 different strategies, pars plana vitrectomy (PPV), scleral buckle (SB), and pneumatic retinopexy (PnR) from the health care payer perspective over a lifetime. Model-based cost-utility analysis. A simulated cohort of 100,000 adult patients (≥18 years old) requiring primary noncomplex RRD repair in theoretical surgical centers in the United States. Quality-adjusted life years (QALYs), lifetime costs (2022 United States dollars), and the incremental cost-effectiveness ratio (ICER) of the 3 interventions were projected over a lifetime horizon, with a cost-effectiveness threshold of ≤$50,000 per gained QALY. Based on inputted parameters, the primary anatomical success was highest for PPV (95.00%) compared to SB (91.76%) and PnR (63.41%). The QALYs associated with PPV, SB, and PnR were (11.87, SD 1.62), (11.84, SD 1.63), and (11.59, SD 1.72), respectively. The incurred lifetime costs of RRD repair and associated postoperative surgeries for PPV, SB, and PnR were $4445.72 (SD 655.75), $4518.04 (662.92), and $3978.45 (728.50), respectively. Parameter-level simulations suggested that PPV was most likely to be the most cost-effective therapy compared to SB and PnR beyond a threshold of $3000/QALY. The incremental cost-effectiveness ratio for PPV compared to PnR was $1693.54. SB was dominant in all scenarios. Threshold analyses indicated that the success rate of PnR would have to be 100% and/or the cost would have to be $2000 or less over lifetime for it to be more cost-effective than PPV. This study found PPV to be the most cost-effective primary procedure for RRD repair at a threshold of $50,000/QALY gained over a lifetime horizon from the health care payer perspective.
