Evaluating Geographic Access to Interdisciplinary Laryngology and Speech-Language Pathology Clinic Models in the Southeast Region of the United States.

OBJECTIVE: An interdisciplinary model of care for the evaluation and treatment of voice, swallowing, and upper airway disorders with laryngologists and specialized speech-language pathologists is known to increase revenue, attendance to visits, patient adherence, and most importantly, improve patient outcomes. Individuals who live outside of areas with high population density often have reduced geographic access to this specialized care. The primary aim of this study is to identify the percentage of the population that has an "extended drive time" to access an interdisciplinary clinic in the Southeast region of the United States.

STUDY DESIGN: NA.

METHODS: Interdisciplinary laryngology and speech-language pathology clinics were identified via publicly accessible information including an internet search and state department of public health databases. Included clinics had at least one full-time fellowship-trained laryngologist and at least one full-time speech-language pathologist on staff. Descriptive statistics and visual representation of the results were achieved with the use of Smappen, a location intelligence online platform, to identify the percent of the population with a drive time greater than 1 hour.

RESULTS: 47.24% of the Southeast population of the United States must drive over 1 hour to access an interdisciplinary clinic. Visual representations of these data are included and generated by Smappen.

CONCLUSIONS: While close geographic proximity does not ensure access to care, it can increase the likelihood that healthcare services will be used. This study identified the population in the Southeast region of the United States with extended drive time to interdisciplinary voice and swallowing centers due to their geographic distance from these centers. The results from this study support the need for increased geographic access to specialty care clinics, specifically voice, swallowing, and upper airway care, and provide insight into potential sites for interdisciplinary centers based on population density in areas that are underserved.
