Progressive Tinnitus Management at Two Veterans Affairs Medical Centers: Clinical Implementation With Modified Protocols

Abstract

Purpose This is a description of the clinical implementation and outcomes of progressive tinnitus management (PTM) at 2 Veterans Affairs (VA) medical centers: Both programs modified the protocol originally described by PTM developers. Method Modifications at both sites were classified according to an evidence-based framework set forth by Stirman, Miller, Toder, and Calloway (2013) . The Iowa City VA PTM program clinicians made 2 modifications and the Asheville, North Carolina, VA PTM program clinicians made 6 modifications to the standard PTM protocol. Pre–post outcome measures were analyzed for 20 veterans who completed the Iowa City program and for 200 veterans who completed the Asheville program. Results Veterans who completed the Iowa City program showed a statistically significant decrease in the average Tinnitus Handicap Inventory score ( Newman, Jacobson, & Spitzer, 1996 ). Veterans who completed the Asheville PTM program showed a statistically significant decrease in the average Tinnitus Functional Index (TFI) score. Outcomes in Asheville were compared to outcomes of a clinical trial of PTM conducted by the developers of PTM. The clinical work in Asheville resulted in a greater mean reduction on the TFI and a larger effect size using the TFI as compared to the results of the PTM clinical trial. Conclusions Clinician-directed modifications to PTM that are made to address the unique needs and circumstances of an individual clinic have potential to result in positive outcomes for patients. Clinicians providing care for patients with tinnitus using PTM who modify the protocol to meet the needs of their local setting are encouraged to collect and report the outcomes of their modifications to improve understanding of the impact of various types of modifications to PTM and other evidence-based practices.
