More than 600,000 people in the United States live with Crohn's disease, a chronic and progressive disorder of the digestive system which is most prevalent in young adults ages 18-35. The Chronology.MD team developed two mobile applications to help patients who have Crohn's disease create visually aided narratives of their condition and responses to treatment. Crohn's patients used the Chronology app to enter observations of daily living (e.g., levels of abdominal pain, energy, and stress); enter clinical data (levels of B-12, C-Reactive Protein, HTC and iron in the blood); automatically upload weight data using Withings scales; and automatically uploaded sleep and exercise data from Fitbit body monitors. The Crohnograph app enabled patients to view time trends for tracked ODLs and other data, explore possible associations among them, and show the data visualizations to their health care provider. The providers could document information from the visualization and conversations in clinical notes. This data collection comprises the data collected using the Chronology app from the patients who participated in the Chronology.MD study.
