Traveling an audiologist to provide otolaryngology care using store-and-forward telemedicine

This project increased access to otolaryngology services by having an audiologist travel to remote Alaska and communicate with an otolaryngologist using store-and-forward electronic consultation. The audiologist was instructed to effectively image appropriate parts of the otolaryngology exam and create telemedicine cases that included clinical histories, images, audiograms, tympanograms, otoacoustic emission testing and/or other documents. The otolaryngology consultants reviewed new referrals as well as follow up cases and made treatment and triage recommendations. Over a 57 month period, 54 trips were made to 14 villages providing 197 clinic service days. The 1,458 patient encounters resulted in referral for surgery or special diagnostic testing 26%, referral for monitoring 23%, starting of medications 19%, referral to regional ENT clinic 15%, and referral to another specialty 5%. Approximately 27% patients did not need to see the otolaryngologist and were triaged out of the specialty clinic. The total cost to run this project was $141,114. Travel was prevented for 85% encounters, resulting in travel cost avoidance in airfare of $496,420. These services were provided at a significantly lower cost and with fewer burdens to the patients when compared to the standard referral system. An audiologist that travels to remote locations and uses store-and-forward telemedicine can rapidly deliver otolaryngology services. This model is a proven mechanism of efficient healthcare delivery that may be expanded to other specialties.
