Voice Therapy Project

Seth Cohen, MD, MPH is the principal investigator on the Voice Therapy Administrative Supplement study funded by National Institute on Deafness and Other Communication Disorders (NIDCD). Collaborators on the study included Stephanie Misono, MD, MPH, University of Minnesota and Nelson Roy, PhD, M.Cl.Sc., University of Utah.

The study aims to:

  1. Assess current perceptions and utilization of voice therapy by otolaryngologists and speech language pathologists in the treatment of patients with voice disorders.
  2. Determine preferences, attitudes, barriers, and benefits of voice disorder treatments from a patient perspective.

The study met recruitment goals (n=500), the database is closed and being analyzed. The results of the study will be submitted for publication within the year.

Impact of Voice Disorders

A study of over 1300 adults found that:

  • Almost 30% of participants had been affected by a voice disorder at some point in their lives.
  • 2% of employed participants missed at least one day in the past year because of a voice disorder
  • 2% reported missing four or more days of work for a voice-related issue.

The study concluded: “Given these estimates, the economic costs incurred—in the U.S. alone—because of voice-related absenteeism and lost productivity, along with medical and behavioral interventions aimed to restore the voice, is likely staggering.”
