- Diagnosis by parent-submitted smartphone photographs has high concordance with in-person diagnosis in patients with pediatric dermatology.
Why this matters
- Teledermatology can improve access to care and reduce time to treatment in a cost-effective manner.
- Overall concordance between photo-based and in-person diagnosis was 83% (95% CI, 71%-94%; Cohen κ=0.81).
- Concordance was 89% (95% CI, 75%-97%; Cohen κ=0.88) in patients with photos considered high enough quality to make a diagnosis.
- Concordance was 64% for alopecia, 67% for nodules and tumors, 92% for rash, 100% for birthmark, 100% for pigmented lesions, and 100% for morphea.
- Image quality differed based on whether or not a diagnosis could be provided (mean photograph quality rating score with diagnosis rendered, 8.9; mean score with no diagnosis, 7.0; P=.001)
- Parents who received instructions on how to take photographs had similar concordance rates as those who did not (85% vs 80%; P=.68).
- 40 pediatric dermatology patients and their parents were analyzed for diagnostic concordance between submitted photographs and in-person diagnosis.
