The Harvey-Bradshaw Index Adapted to a Mobile Application Compared with In-Clinic Assessment: The MediCrohn Study.

Mobile apps are useful tools in e-health and self-management strategies in disease monitoring. We evaluated the Harvey-Bradshaw index (HBI) mobile app self-administered by the patient to see if its results agreed with HBI in-clinic assessed by a physician. Patients were enrolled in a 4-month prospective study with clinical assessments at months 1 and 4.
