Telemedicine-assisted neurotology in post-Katrina Southeast Louisiana.

OBJECTIVE: This study evaluates technical requirements, privacy and legal constraints, reimbursement considerations, and overall feasibility of a new telemedicine neurotologic patient care delivery model in post-Katrina, Southeast Louisiana. METHODS: This study is a retrospective review of the first year of a telemedicine neurotology practice with limited on-site neurotology physician availability (3-days monthly) with a full-time on-site audiologist, a full-time specialty-trained nurse practitioner, full-time neurosurgery on-site availability, and full-time otolaryngology on-site availability. RESULTS: A combined "store-and-forward" and "real-time" telemedicine delivery model was implemented for a new neurotology practice. Technical requirements include secure data transfer, real-time video-streaming, high-quality video otoscopy and microscopy, infrared video eye movement visualization and recording, remote visualization of radiologic imaging studies, and formalized diagnostic algorithms for patient evaluation. Telemedicine patient evaluations occur with the patient in Baton Rouge, LA, while the examining neurotologist is linked through a secure, commercially available communication connection in Pittsburgh, PA. Specifically designed consent forms and bilocation licensing and liability insurance coverage were required. Third-party payers were consulted before implementation to assure adherence to local reimbursement requirements. During the first 12 months of operation, 450 patient encounters were accomplished purely through telemedicine, with an additional 800 on-site patient visits and 150 operative procedures, including 24 neurotologic skull base procedures. CONCLUSION: Telemedicine is a viable delivery model for neurotology care delivery. Planning and implementation of such a model requires systematic considerations of medical, nursing, information systems, legal, reimbursement, and management parameters. Although the authors' initial motivation for this model was the resource-restricted, post-Katrina health care environment in South Louisiana, this delivery model has wider applicability in otolaryngology, other medical specialties, humanitarian outreach, and medical education. Prospective assessment of clinical outcomes and patient satisfaction is ongoing for objective validation of this delivery model.

Absent or elevated middle ear muscle reflexes in the presence of normal otoacoustic emissions: a universal finding in 136 cases of auditory neuropathy/dys-synchrony.

We extracted a subpopulation of 136 patients (from our database of 257 AN/AD subjects) in whom middle ear muscle reflexes had been measured. None showed normal reflexes at all frequencies tested. Only three subjects showed any reflexes at 95 dB HL or below, but never at both 1 and 2 kHz in both ears whether ipsilaterally or contralaterally elicited. All the other reflex measures in these remaining 133 patients were either absent or observed above 100 dB HL, which is incongruous with their normal otoacoustic emissions throughout the frequency bands. Therefore, we urge colleagues to test ipsilateral middle ear muscle reflex at least at 1 kHz and 2 kHz in any perinatal hearing screening that depends solely on otoacoustic emissions. If the emissions are present and the reflexes are absent or elevated, an ABR may be required to properly intervene, because the management of AN/AD patients often differs drastically from what the behavioral audiogram or the ABR suggest.
