title: Patient-Reported Outcome Measures: How Do Digital Tablets Stack Up to Paper Forms? A Randomized, Controlled Study.
abstract: Patient-reported outcomes (PROs) are essential to assessing the effectiveness of care, and many general-health and disease-specific PROs have been developed. Until recently, data were collected predominantly with pen-and-paper questionnaires. Now, though, there is a potential role for electronic medical records in data collection. In this study, patients were randomly assigned to complete either tablet or paper questionnaires. They were surveyed on patient demographics, patterns of electronic device use, general-health and disease-specific PROs, and satisfaction. The primary outcome measure was survey completion rate. Secondary outcome measures were total time for completion, number of questions left unanswered on incomplete surveys, patient satisfaction, and survey preferences. The study included 483 patients (258 in tablet group, 225 in paper group), and the overall completion rate was 84.4%. There was no significant difference in PRO completion between the tablet and paper groups. Time to completion did not differ between the groups, but their satisfaction rates were similar. However, more paper group patients reported a preference for a tablet survey. Advantages of digital data collection include simple and reliable data storage, ability to improve completion rates by requiring patients to answer all questions, and development of interface adaptations to accommodate patients with handicaps. Given our data and these theoretical benefits, we recommend using tablet data collection systems for PROs.
