title: Tele-ABR using a satellite connection in a mobile van for newborn hearing testing.
abstract: We assessed the feasibility of conducting Auditory Brainstem Response (ABR) testing in a mobile van with satellite connectivity, with the help of trained health workers. ABR recordings in newborn babies made by telemedicine were compared with recordings made face to face. The auditory evoked response equipment was controlled by an audiologist at a nearby hospital. Videoconferencing was used during the testing process to monitor patient preparation by the village health worker. A total of 24 newborns (13 male and 11 female) aged 8-30 days underwent ABR in face-to-face and tele-mode. There was no significant difference between peak V latency measured at three intensity levels in the two modes. Agreement between the two methods of measurement was examined with a Bland-Altman plot. Almost all points were within the limits of agreement, suggesting no bias in the telemedicine measurements. Real-time tele-ABR testing as a component of newborn hearing screening is feasible in a mobile van using satellite link with the assistance of village health workers.
