Potential Risks for Healthcare Disparities Among Individuals With Voice and Upper Airway Disorders: A Systematic Review

Impact of social determinants of health on rehabilitation service use and outcomes in adults in the USA: a scoping review protocol

INTRODUCTION

Many Americans fail to receive equitable access to or positive outcomes from rehabilitation services. These disparities result from broader societal inequities that disproportionately affect certain groups of people due to non-medical factors such as race, gender, education and living status. This scoping review aims to describe research papers that examine social determinants of health (SDOH) that underlie disparities in access to, use of, or outcomes related to rehabilitation (in occupational therapy, physical therapy, recreational therapy, rehabilitation medicine/physiatry and speech-language pathology) among adults in the USA. Identifying SDOH-related factors that drive inequities in rehabilitation will inform the development of potential solutions to improve access, professional education and patient outcomes.

METHODS AND ANALYSIS

The Joanna Briggs Institute methodological framework will be used to conduct this scoping review. To meet the inclusion criteria, articles will need to be published in English since 2013, be classified as full-length original research, include at least 100 sampled adults, be conducted in the USA or its territories, and investigate SDOH-related disparities in rehabilitation. Search terms will include SDOH, rehabilitation and disparities. Five databases (Embase, PubMed, Scopus, Sociological Abstracts and Web of Science: Core Collection) will be searched for articles published in English between 2013 and 2023. Records from these databases as well as reference lists of included papers and review papers will be screened for eligibility. Two people will independently review each record during title and abstract screening and full-text screening, and three people will independently extract data. Screening and data extraction processes will be piloted. The results will be presented in tables, graphs and narrative summaries.

ETHICS AND DISSEMINATION

Findings will be disseminated through scientific conferences, professional networks, stakeholder meetings, invited workshops and webinars, email listservs of professional associations, academic social media and in a peer-reviewed journal. Ethics approval is not required as the review will only include previously published data.

Updated Acoustic Normative Data through the Lifespan: A Scoping Review

OBJECTIVE

To assess the recent literature for voice acoustic data values reported for individuals without voice disorder through the lifespan as a means to develop an updated normative acoustic data resource for children and adults.

METHODS

A scoping review was conducted using the Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR) Checklist. English language, full-text publications were identified through Medline (EBSCO & OVID), PubMed, APA PsycINFO, Web of Science, Google Scholar, and ProQuest Theses and Dissertations Global.

RESULTS

A total of 903 sources were retrieved; of these 510 were duplicates. Abstracts of 393 were screened, with 68 full-text review. From the eligible studies, citation review yielded 51 additional resources. Twenty-eight sources were included for data extraction. For the normative acoustic data extracted for males and females across the lifespan, lower fundamental frequency for adult females was observed and few studies collected semitone range, sound level range, or frequency range. Data extraction also indicated a predominately gender binary reporting of acoustic measures with few studies reporting gender identity, race, or ethnicity as variables of interest.

CONCLUSIONS

The scoping review yielded updated acoustic normative data that is of value for clinicians and researchers who rely on this normative data to make determinations about vocal function. The limited availability of acoustic data by gender, race, and ethnicity creates barriers for generalization of these normative values across all patients, clients, and research volunteers.

Sex and Race Reporting and Representation in Noncancerous Voice Clinical Trials: A Meta-Analysis of National Institutes of Health-Registered Research Between 1988 and 2021

PURPOSE

The purpose of this meta-analysis was to assess the frequency of sex, race, and ethnicity reporting and proportional representation in funded, noncancerous voice clinical trials to determine the state of compliance with National Institutes of Health (NIH) guidelines for inclusivity in clinical research.

METHOD

Clinical trials registered with the NIH/U.S. National Library of Medicine between January 1988 and September 2021 were analyzed. Primary reports of the trials were obtained from clinicaltrials.gov and PubMed. Outcomes included the proportion of trials reporting sex, race, and ethnicity and the proportion of participants by sex, race, and ethnicity in the trials. Descriptive statistics and chi-square tests were used to analyze the data with 95% confidence intervals (CIs) reported.

RESULTS

The search yielded 46 research studies. After inclusion and exclusion criteria were applied and attempts to locate studies were conducted, 11 total articles were ultimately evaluated. Descriptively, there were more female subjects, yet overall, no significant difference in sex distribution (χ² = 0.07, p = .75, 95% CI [-0.25, -0.19]). Race and ethnicity were only reported in two clinical trials. Black participants were underrepresented in one clinical trial (χ² = 4.93, p = .02, 95% CI [-0.11, -0.02]), whereas Hispanic participants were underrepresented in a second trial (χ² = 11.27, p < .00, 95% CI [-0.20, - 0.13]).

CONCLUSIONS

This preliminary analysis highlights the disparities in race and ethnicity recruitment and reporting in noncancerous voice clinical trials. There is a need for strategic recruitment strategies and improved reporting practices to adhere to the NIH inclusivity directives.
