Developing a synchronous otolaryngology telemedicine Clinic: Prospective study to assess fidelity and diagnostic concordance

Objective

To evaluate diagnostic concordance of a synchronous telemedicine otolaryngology clinic with use of currently available technology.

Study Design

Prospective.

Methods

Patients in a rural otolaryngology clinic were enrolled in a pilot telemedicine clinic. To assess system fidelity, an on-site and remote (consulting) otolaryngologist conducted simultaneous patient evaluations using streaming telecommunication technology for all aspects of the clinical encounter, including high-definition examination and endoscopic images. Both physicians and patients were blinded and diagnoses recorded. Post-encounter physician surveys and an original patient-centered TeleENT Satisfaction Questionnaire (TESQ) were used to assess overall satisfaction.

Results

Twenty-one patients were enrolled consecutively. Visual technology was found acceptable in all cases, and audio technology was acceptable in 20 of 21 encounters. Patient satisfaction was 96%, and patients felt comfortable using a telemedicine system in the future. Encounters were not significantly longer than traditional encounters. Physician diagnostic agreement was found in 95% of cases, and the consulting physician indicated that all encounters provided sufficient history, examination, and high-quality images to generate an accurate diagnosis, order additional workup, and/or make an appropriate referral.

Conclusion

A synchronous otolaryngology telemedicine clinic is comparable to a standard clinic in terms of diagnostic concordance and patient satisfaction when using streaming technology and high-definition images. Using telemedical technology may be a viable way to increase otolaryngology access in remote or underserved areas. With system validity now established, future studies will assess the feasibility of using trained on-site physician extenders (nurse practitioners or physician assistants) to conduct in-person patient encounters with remote otolaryngologist support.
