A Follow-Up Clinical Trial Evaluating the Consumer-Decides Service Delivery Model.

ABSTRACT: Objectives There were 2 main objectives. The primary objective was to replicate a prior clinical trial of a consumer-decides (CD) approach to selecting hearing aids in older adults as a potential model for over-the-counter (OTC) intervention using less front-end screening of participants and a wider range of frequency-gain characteristics in the devices. The 2nd objective, only feasible if participant choices allowed, was to evaluate the efficacy of the CD approach relative to a CD-based placebo device. Design The design of this study is a single-site, prospective, double-blind clinical trial. Outcome measures were obtained after a typical 4- to 5-week trial period. An optional follow-up of a 4-week audiology-based (AB) best practices trial was also included for replication and comparison
