title: An economic evaluation of oral compared with intravenous ganciclovir for maintenance treatment of newly diagnosed cytomegalovirus retinitis in AIDS patients.
abstract: This prospective, clinical economic study was done to determine the cost impact of oral compared with intravenous (i.v.) ganciclovir for the maintenance treatment of newly diagnosed cytomegalovirus (CMV) retinitis in patients with acquired immunodeficiency syndrome (AIDS). Efficacy and safety data were extracted from a trial of oral and i.v. ganciclovir. Medical care utilization and reimbursement data were obtained from the clinical trial, a survey of home care and nursing companies, an 11-member physician panel, and a Medicaid cost database. The primary outcome measures were time to first retinitis progression and associated direct medical care expenditures. Nonmedical costs and quality-of-life benefits were not considered. Based on masked evaluation of retinal photographs, the Kaplan-Meier mean time to first progression was 62 days for i.v. ganciclovir and 57 days for oral ganciclovir (a nonsignificant difference). he expected mean cost of treatment for i.v. ganciclovir was significantly different at $8587.00 compared with $4938.00 for oral treatment. Sensitivity analysis using funduscopically determined mean time to first progression showed similar cost savings. We concluded that oral ganciclovir is a cost-saving alternative to i.v. ganciclovir for the maintenance treatment of AIDS patients with newly diagnosed CMV retinitis. Cost differences are attributable to reduced home care expenditures and lower incidence and costs of treating major adverse events in the oral treatment group.
