Pediatric Emergency Department Smartphone Otoscope Study (PED-Oto)

2016-09-29 23:08:22 | BioPortfolio


Acute otitis media (AOM), defined as acute inflammation in the middle ear, is a leading cause of health encounters and antimicrobial prescriptions in children worldwide. Diagnosis of AOM is often dependent on a brief view of the tympanic membrane in an uncooperative child's ear canal. As a consequence, AOM may be inappropriately diagnosed when visualization of the tympanic membrane (ear drum) is not optimal. Improved methods for visualizing the tympanic membrane including capturing still images and recording video of the ear exam would be beneficial in the diagnosis and management of otic complaints, including acute and chronic otitis media. Use of a smartphone otoscope has the potential to optimize clinician ability to manage otic complaints, visualize the tympanic membrane, and support antimicrobial stewardship. This study will be conducted as a randomized control study in two affiliated children's hospital emergency departments. Twenty volunteer clinicians will be randomly assigned to use either a smartphone otoscope or a conventional otoscope for all otic examinations for a 6-month period.


A smartphone otoscope (CellScope-Oto) is a pocket size attachment that employs the technology and light source of a smartphone to capture reproducible images of the ear canal and tympanic membrane. Previous studies with this device demonstrated that images taken with both the smartphone otoscope and a camera-fitted conventional analogue otoscope were equivalent with respect to image quality and that the smartphone otoscope was acceptable as an educational and diagnostic tool to health professional students. A pilot study with a similar design to this study conducted in two offices of an ambulatory pediatric clinic demonstrated a trend toward decreased antimicrobial prescription filling among families whose children were examined with the smartphone otoscope compared to those who were examined with a conventional otoscope. To further assess this trend, this study proposes an evaluation of the impact of device use on antimicrobial prescribing for children with an otic complaint in a pediatric emergency department (PED) setting. This study will enroll 20 clinicians for the 6-month study period; 10 who will be randomly assigned to use a smartphone otoscope for the 6-month study period and 10 who will be assigned to use a conventional otoscope for all otoscopic exams. Data will be abstracted via retrospective review of the electronic medical record of encounters in with an otoscopic exam was performed as part of the diagnostic evaluation.

Medical and Biotech [MESH] Definitions

Examination of the EAR CANAL and eardrum with an OTOSCOPE.

Inflammation of the ear, which may be marked by pain (EARACHE), fever, HEARING DISORDERS, and VERTIGO. Inflammation of the external ear is OTITIS EXTERNA; of the middle ear, OTITIS MEDIA; of the inner ear, LABYRINTHITIS.

Instruments designed to inspect or auscultate the ear. They are designed primarily to examine the outer ear canal and tympanic membrane by means of light and air under moderate pressure, as with a pneumatic otoscope. (UMDNS, 1999)

Inflammation of the middle ear with purulent discharge.

Inflammation of the honeycomb-like MASTOID BONE in the skull just behind the ear. It is usually a complication of OTITIS MEDIA.
