Objectives: The inclusion of patient-reported outcomes (PROs) in randomized controlled trials (RCTs) supplements treatment efficacy outcomes with patient perspectives. Therefore, the aim of this study was to evaluate reporting completeness of PROs in RCTs pertaining to tinnitus, using the Consolidated Standards of Reporting Trials (CONSORT-PRO) adaptation.

Methods: We performed a search of MEDLINE, Embase, and Cochrane Central Register of Controlled Trials (CENTRAL) for published RCTs related to tinnitus with at least one PRO measure from 2006- 2020. Two investigators screened RCTs for inclusion. Using the CONSORT-PRO adaptation in an independent, masked fashion, investigators then evaluated all included RCTs. Similarly, all RCTs were evaluated using the Cochrane Collaboration Risk of Bias 2.0 tool. To assess relationships between trial characteristics and completeness of reporting, bivariate regression analyses were used.

Results: From 878 publications, 37 RCTs met inclusion criteria. The mean CONSORT-PRO completeness of reporting across RCTs was 51.17% (SD=20.82). Evaluation of our secondary outcome – – assessment of study characteristics –– demonstrated significantly higher completeness of reporting when
(1) the CONSORT guideline was mentioned within the RCT (p=.01),
(2) trials had ‘some concerns’ for bias (p=.001), and
(3) trials had ‘low’ risk of bias (p=.001).

Conclusion: Our study found that there was subpar CONSORT-PRO adherence within tinnitus RCTs. Due to the variance in symptom severity in tinnitus and the importance of PROs to clinical practice, were commend journals include instructions to authors to use the CONSORT-PRO guideline before the publication of RCTs.
