Popis: | Objectives As more HIV-positive individuals receive antiretroviral therapy (ART), payers are seeking options for covering these increased and sustained drug costs. Strategic use of available generic antiretroviral (ARV) formulations may be feasible. De-simplifying a single-tablet co-formulation (STF) into two or more tablets using both brand and generic drugs has been proposed. We determine if voluntary de-simplification of one STF could be utilized as a cost-saving strategy. We report on the challenges, uptake, outcomes and cost savings of this initiative. Methods Patients stable on the most commonly used STF (Triumeq® ) were offered the option of remaining on Triumeq® or switching to generic abacavir/lamivudine and Tivicay® between 1 January 2015 and 1 January 2018; those starting ART consisting of abacavir/lamivudine/doulutegravir in the same period were offered the option of starting Triumeq® or generic abacavir/laminvudine and Tivicay® . No incentives were provided. We examined the acceptance/decline rates, patient satisfaction, health care outcomes and annual cost savings. Results Of 626 patients receiving Triumeq® , 321 were approached; 177 (55.1%) agreed to de-simplify. Of patients initiating ART, 62.7% chose the generic co-formulation. Patients switching to or starting on the generic co-formulation were more likely to be male, > 45 years old, Caucasian, men who have sex with men (MSM) and more HIV-experienced, and to have more comorbidities (all P 500 HIV-1 RNA copies/mL after baseline was 2.7% in switched patients compared with 7.0% in those declining to switch. No de novo resistance occurred. A saving of Cdn$1 319 686 was achieved in the first year. Conclusions Reliance on altruism, while respecting patient autonomy, achieved de-simplification in > 50% of patients approached, and generated immediate cost savings with no increased risk of adverse events, viral breakthrough or resistance. |
