Study Summary
The Cellscope is an iPhone-based otoscope that uses the iPhone camera and light source to capture HIPAA compliant images and video recordings of the external and middle ear structure. This technology allows multiple providers, at different levels of training, the ability to simultaneously exam a child's external and middle ear structures. The investigators hypothesize this device will result in improved concordance in trainee/supervisor exam findings, increase trainee confidence in exam findings, decreased antibiotic prescriptions, and fewer repeat exams by multiple providers. Thus, this study has the potential to improve physician training and examination confidence, decrease the unnecessary use of antibiotics, and improve the patient/caregiver experience in healthcare interactions.
Primary Outcome
Concordance of trainee and supervisor utilizing the OMgrade scale, between traditional otoscope and cellscope. Concordance is determined by the concordance-statistic (0-1) in a logistic regression model. The closer the number is to 1 the higher the concordance.
