Data
Comorbidity
Patient data obtained from Way to Health included demographics collected by survey during initial hospitalization (age, gender, race/ethnicity, education, marital status, annual household income, and body mass index) and RPM activity patterns transmitted from the smartphone application and wearable including daily measures of step counts, distance, calories burned (active and total), minutes of activity (soft and moderate intensity), minutes of sleep (total, light, and deep), minutes to fall asleep, minutes awake, and number of times awakened. The smartphone application alone did not track sleep but patients in that arm could manually input sleep on their own. Data obtained from the electronic health record included insurance type, the Charlson Comorbidity Index
