ABSTRACT
OBJECTIVE:
Large-scale otoscopic and audiometric assessment of populations is difficult due to logistic impracticalities, particularly in low- and middle-income countries (LMIC). We report a novel assessment methodology based on training local field workers, advances in audiometric testing equipment and cloud-based technology.METHODS:
Prospective observational study in Bohol, Philippines. A U.S. otolaryngologist/audiologist team trained 5 local nurses on all procedures in a didactic and hands-on process. An operating otoscope (Welch-AllynR) was used to clear cerumen and view the tympanic membrane, images of which were recorded using a video otoscope (JedMedR). Subjects underwent tympanometry and distortion product otoacoustic emission (DPOAE) (Path SentieroR), and underwent screening audiometry using noise cancelling headphones and a handheld Android device (HearScreenR). Sound-booth audiometry was reserved for failed subjects. Data were uploaded to a REDCap database. Teenage children previously enrolled in a 2000-2004 Phase 3 pneumococcal conjugate vaccine trial, were the subjects of the trainees.RESULTS:
During 4 days of training, 47 Filipino children (M/Fâ¯=â¯28/19; mean/median ageâ¯=â¯14.6/14.6 years) were the subjects of the trainee nurses. After the training, all nurses could perform all procedures independently. Otoscopic findings by ears included normal (Nâ¯=â¯77), otitis media with effusion (Nâ¯=â¯2), myringosclerosis (Nâ¯=â¯5), healed perforation (Nâ¯=â¯6), perforation (Nâ¯=â¯2) and retraction pocket/cholesteatoma (Nâ¯=â¯2). Abnormal audiometric findings included tympanogram (Nâ¯=â¯4), DPOAE (Nâ¯=â¯4) and screening audiometry (Nâ¯=â¯0).CONCLUSION:
Training of local nurses has been shown to be robust and this methodology overcomes challenges of distant large-scale population otologic/audiometric assessment.Palavras-chave
