LO89: The effectiveness of video discharge instructions for acute otitis media in children: a randomized controlled trial

Introduction: In children, acute otitis media (AOM) pain is undertreated. We sought to determine if video discharge instructions were associated with improved symptomatology, functional outcomes, and knowledge compared to a paper handout. Methods: We conducted a randomized controlled superiority trial comparing video discharge instructions (Easy Sketch Pro3TM) on management of pain to a paper handout detailing the same. We included caregivers of children 6 months to 5 years presenting to the emergency department (ED) with a clinical diagnosis of AOM. The primary outcome was symptomatology using the Acute Otitis Media Severity of Symptom (AOM SOS) score between 48 and 72 hours. The 7-item self-report AOM-SOS is scored from 0 to 13 with a higher score indicating more symptomatology. Secondary outcomes included knowledge gain using a 10-item survey, days of daycare/school/work missed, and recidivism. Assuming a minimal clinically important AOM-SOS difference of 2, 90% power, and 5% alpha, 60 individuals/group was needed. Results: 219 caregivers were randomized and 149 completed the 72-hour follow-up (72 paper and 77 video). The median (IQR) AOM-SOS score in the video group (adjusted for pre-intervention AOM-SOS, analgesic and antibiotic use) was significantly lower than paper [8 (7,11) versus 10 (7,13), respectively, p=0.004]. There were no significant differences between video and paper in the mean (SD) knowledge score [9.2 (1.3) versus 8.8 (1.8) correct answers, respectively, p=0.07], mean (SD) number that returned to a health provider [8/77 versus 10/72, respectively, p=0.49), mean (SD) number of daycare/schooldays missed [1.2 (1.5) versus 1.1 (2.1), respectively, p=0.62], and mean (SD) number of workdays missed by caregiver [0.5 (1) versus 0.8 (2), respectively, p=0.05]. Conclusion: Video discharge instructions are associated with less symptomatology compared to a paper handout, are effective for caregiver education in the ED, and should be used routinely.
