Intracameral moxifloxacin for endophthalmitis prophylaxis after cataract surgery: Cost-effectiveness analysis
Abstract
PURPOSE
To determine the cost-effectiveness of intracameral moxifloxacin compared with traditional antibiotic prophylaxis in preventing endophthalmitis after cataract surgery.
SETTING
Theoretical surgical center in the United States.
DESIGN
Evaluation of technology.
METHODS
The incremental cost-effectiveness ratios (ICER) and incremental cost-utility ratios (ICUR) were calculated for patients having cataract surgery with traditional antibiotic prophylaxis (perioperative topical antibiotics) compared with perioperative topical antibiotics with intracameral moxifloxacin. The base case was a healthy binocular 73-year-old man having first-eye cataract surgery. The incidences and costs were derived from PubMed English literature searches, Medicare reimbursement rates, and average wholesale prices. All costs and benefits were adjusted 3% per annum and for inflation to 2017 United States dollars. Deterministic and probabilistic sensitivity analyses were performed to assess uncertainty.
RESULTS
Compared with traditional prophylaxis, an adjuvant 500 μg intracameral moxifloxacin (for $20) was cost-saving from a societal perspective in the base case; in probabilistic sensitivity analyses, all the values were within the societal willingness-to-pay threshold of $50 000/quality-adjusted-life-years (QALYs), and 6142 (61%) of 10 000 iterations were cost-saving. From a healthcare sector perspective, intracameral moxifloxacin was cost-effective, with an ICUR of $8275/QALY. In cases with…
