Training of nurses in ear examination and hearing screening in the school setting (Phase II): A cross-sectional study

OBJECTIVES:To determine the agreement between 1) ear examination findings of the otorhinolaryngologist using an otoscope and trained elementary school nurses using a penlight, 2) hearing screening findings of the otorhinolaryngologist and elementary school nurses, both using the Philippine National Ear Institute (PNEI) Method of 512 Hz Tuning Fork Test (TFT) and 3) PNEI Method of 512 Hz TFT findings and screening audiometry findings.METHODS:In this continuing study, nurses residing in the venue of the study, and previously trained in ear examination using a penlight and hearing screening using the PNEI 512 Hz TFT, conducted these in school children who attended the hearing screening and medical mission. Otoscopy, PNEI Method of 512 Hz TFT, and screening audiometry were then conducted on the children by the otolaryngologist. The nurses and the otolaryngologist performed independent and blinded assessments.RESULTS:Eighteen nurses and ninety children participated in the study. Data subjected to Kappa statistics showed good agreement between nurses and otorhinolaryngologist's findings in the examination of the external canal and tympanic membrane and in PNEI Method of 512 Hz TFTs, and between the PNEI Method of 512 Hz TFT and screening audiometry.CONCLUSION:PNEI methods of penlight ear examination and 512 Hz TFT may be effective tools for early detection of common ear conditions and hearing screening in Filipino school children. These may be conducted in the school setting not only by otorhinolaryngologists but also by adequately trained school nurses.

Training of nurses in ear examination and hearing screening in the school setting.

The objectives of this study were to determine the agreement between the ear examination findings of the otorhinolaryngologist (trainer) and the elementary school nurse (trainee) after training with the use of a penlight and to determine the mean sound pressure level (SPL) produced by school nurses as a standard parameter for hearing screening using a 512 tuning fork after training on tuning fork testing by the otorhinolaryngologist. Training workshops in ear examination using a penlight and hearing screening using a 512 tuning fork were conducted for school nurses. Data for assessment of ear examination skills and production of SPL were collected by questionnaire and observation of performance. Kappa statistics were used to assess agreement between trainees' and trainer's responses. Mean and standard deviation were determined for the assessment of the SPL produced. Results showed an excellent agreement between the school nurses' and otorhinolaryngologist's observations on ear examination. These included observations of the ear canal, visualization of the tympanic membrane and identification of unusual findings such as wax and discharge. The majority of nurses responded positively in terms of the ease and confidence in performance of the procedure. Regarding tuning fork testing, the nurses were able to produce significant SPL. The mean SPL produced by the nurses using a 512 tuning fork was 56.316 dB.
