Pharmacoeconomic Analysis of 3 Treatment Strategies for Cytomegalovirus Retinitis in Patients with AIDS
1998
A decision-analytical simulation model was constructed to perform a pharmacoeconomic analysis of the following 3 treatment strategies for previously untreated cytomegalovirus (CMV) retinitis in patients with AIDS: (i) intravenous foscarnet (IVF) for induction and maintenance therapy; (ii) intravenous ganciclovir (IVG) for induction and maintenance therapy; and (iii) intravenous ganciclovir for induction therapy, followed by oral ganciclovir for maintenance therapy (IVG-ORG). Patients who experienced significant adverse effects during, or who failed, initial therapy were switched once to one of the other 2 treatments. The model was used to estimate the direct medical cost (from the perspective of a public payer), survival, and survival adjusted for disutility because of lost vision, for each strategy in the first year following treatment initiation.
