Background/aim: Eosinophilic esophagitis (EoE) is a chronic immune-mediated disease. Telemedicine is a healthcare technology used when a patient is separated by distance. The reliability of the Pediatric Eosinophilic Esophagitis Symptom Score, version 2.0 (PEESS v2.0) for telemedicine applications, has not been studied yet. Therefore, we aimed to evaluate the reliability of PEESS v2.0 for telemedicine. Materials and methods: We sent a telesurvey using questionnaires via electronic telecommunication as the telemedicine method. Children with EoE and their parents were asked to complete PEESS v2.0 with the telesurvey method (unsynchronized with the physician) and attend in-person visits one week apart. Intraclass correlation (ICC), Wilcoxon, and Bland-Altman tests were used as reliability analyses. Reliability was defined as a strong agreement between the measurements in ICC ≥ 0.8 and a p-value of ≤ 0.05 and no statistically significant difference between the scores of the two methods in the Wilcoxon and Bland-Altman analyses, i.e. a p-value of >0.05. Results: The total scores of children and parents were higher in in-person visits than in the telesurvey (Wilcoxon tests, p ≥ 0.05). Bland- Altman analysis showed that the mean difference in total scores between the two methods was significant for both children and parents (p ≥ 0.05). ICC levels for the children and parent scores for the entire group ranged from 0.595 to 0.763 (moderate agreement). Conclusion: Unsynchronized telesurvey use of PEESS v2.0 is unreliable both for children and parents. We suggest testing the reliability of chosen telemedicine methods before using them in clinical and research practice.
