We would assess the benefits of health apps on individuals' health on multiple survey and clinical diagnostic items and compare results between three groups. Group 1: no access to a smart phone; group 2: access to a smart phone, but no use of health apps; group 3: access to a smart phone and use health apps. The goal of this data would be to better develop and design mHealth interventions to improve health outcomes.
Methods: Define RA with EHR algorithm, use mHealth app to record RA symptoms (RADAI), current/new meds + adherence
Outcome: daily RA disease activity after drug start
Data: EHR meds, ESR, CRP; PPI confounders, demographics, smoking, exercise.
Limitations of prior studies: small samples, no adherence or confounder info, sparse outcome data
Expected outcomes:... more »
