Patient reported data integration for management of Eosinophilic Esophagitis.

Eosinophilic Esophagitis (EoE) is an esophageal allergic inflammatory disorder triggered by food proteins. Symptoms of EoE are variable within and between individuals. Presenting symptoms may include dysphagia, food bolus impaction, dyspepsia, or more subtle symptoms such as feeding disorders, regurgitation sensation, or nausea. The development and validation of a pediatric EoE patient self-reported and parent proxy-reported outcome symptom scoring tool was created by Franciosi et al. published in BMJ 2011, titled the Pediatric Eosinophilic Esophagitis Symptom Score (PEESS™ v2.0). To date, its use is largely for research purposes. We propose to evaluate the implementation of the PEESS™ v2.0 in a prospective interventional controlled clinical practice. The study included 620 patients over an 18-month period. Surveys were delivered and administered digitally every month through the MyGeisinger.org Patient Portal. Our analysis demonstrated symptom severity and symptom frequency scores significantly improved over time. However, counter to our hypothesis, patients who completed the PEESS™v2.0 ultimately had higher EoE-related health care utilization of office visits and endoscopies compared with those who did not complete the PEESS™v2.0. This could be related to greater awareness of disease activity and/or increased willingness to seek care. Our study, in the context of mobile health tool and patient-reported outcome trends, represents an opportunity for improved disease monitoring at-home within the field of eosinophilic gastrointestinal diseases.
