PURPOSE: To estimate the financial impact of COVID-19-related shutdowns on ophthalmic surgery performed at hospital outpatient departments (HOPDs) in the United States. SETTING: Nationally representative sample of U.S. hospital payment and cost data. DESIGN: Retrospective review and economic impact analysis. METHODS: The Nationwide Ambulatory Surgery Sample (NASS) was used to identify ophthalmic surgical procedures and associated charges that were performed at HOPDs. The highest volume elective ophthalmic procedures were identified. The total hospital cost and payment amount was calculated for each procedure using the Hospital Outpatient Prospective Payment System (OPPS) maintained by the Centers for Medicare & Medicaid Services. Net facility income (estimated payments less OPPS rates) was determined for each elective surgical procedure category and also stratified by hospital teaching status. RESULTS: In 2017, elective cataract, strabismus, and keratoplasty surgeries were performed 1,230,992 times at HOPDs. The total cost of these elective surgeries was 2,350 million USD, with a total hospital payment of 3,624-3,786 million USD. This led to an estimated net income of 1,278-1,440 million USD overall to U.S. hospitals in the NASS dataset from elective ophthalmic surgery (approximately 107-120 million USD per month), with a larger proportion performed in teaching hospitals. CONCLUSIONS: The cessation of elective ophthalmic surgeries at HOPDs during COVID-19 resulted in a significant loss of income for hospitals in the U.S. as well as teaching experiences for trainees at academic medical centers.
