Financial incentives. One method for increasing delivery of care is contingent administration of monetary incentives; such reinforcements have improved health outcomes related to drug/alcohol abstinence, smoking cessation, childhood vaccination, tuberculosis care and HIV treatment. Co-Investigator Dr. Brooner has extensively studied incentives to increase drug abstinence among injection drug users (IDUs). Contingent reinforcement has also been successfully used to link HIV-infected patients to care and improve adherence to ART. Curative HCV treatments are given for a finite duration (12 weeks) which offers an ideal paradigm for incentive interventions by reducing the overall cost and removing concerns of loss of adherence if incentives are stopped.
