Receipt of treatment among a nationally representative sample of US adults with communication disorders

Abstract

Introduction: A robust body of literature exists on clinical research outcomes for persons with communication disorders (CD). Comparatively few studies have examined population-based health service outcomes for CD-related services, which capture persons with CDs who may not be part of clinical or administrative data. This is important to describe access to treatment and the factors impacting access. We address this gap, describing four CD-related healthcare outcomes among adults reporting problems with communication (voice, speech, and language): (1) utilization, (2) utilization determinants, (3) professionals providing CD care, and (4) patient-reported service-related outcomes.

Methods: We conducted a retrospective, cross-sectional study of community-dwelling adults (≥18 years) in the US self-reporting CD on the nationally representative 2012 National Health Interview Survey. Separate analyses examined adults with voice (n = 1,323), speech (n = 658), and language (n = 396) disorders. We used survey weighted logistic regression to assess the likelihood of treatment, controlling for health, disorder, and sociodemographic characteristics; Pearson's chi square was calculated for other outcomes.

Results: An estimated 10% of adults reporting CD described receiving care addressing their CD. Employment, sociodemographic and economic status, health insurance, level of severity, and presence of co-occurring CD were associated with receiving treatment. Over half of respondents with speech and language disorders and less than a fifth of respondents with voice disorders reported receiving care from speech-language pathologists. Adults who received CD-related services reported improvements in activities (52-69% overall) and CD (33-48% overall).

Conclusions: This population-based study shows that general access to CD services is low. Underserved populations have less access to treatment than their counterparts with more resources. Improving access to CD services requires creative interventions addressing patient and provider needs, as well as healthcare system design. Population-based follow-up studies are necessary to track progress toward improving access to care.
