Abstract
Purpose
This study compared a tablet PC questionnaire with a paper method for reliability and patient preferences in the acquisition of patient-reported outcomes (PROs) for patients treated with radiotherapy. By comparing the two modes of PRO administration, we aimed to evaluate the adequacy of using tablet PC questionnaires in future clinical use.
Methods
Patients were randomized in a crossover study design using two different methods for PRO entry. A group of 89 patients answered a paper questionnaire followed by the tablet PC version, whereas 89 patients in another group completed the tablet PC questionnaire followed by the paper version. Surveys were performed four times per patient throughout the course of the radiotherapy. The Korean versions of the M.D. Anderson Symptom Inventory (MDASI-K) and the Brief Fatigue Inventory (BFI-K) were used. The primary endpoint of our current study was an assessment of patient preference for the survey method. The proportions of patients preferring each mode of questionnaire were evaluated.
Results
The proportion of patients who preferred the tablet PC version, paper form, or who had no preference was 52.2, 22.1, and 25.7 %, respectively. More than half of the patients preferred the tablet PC to the paper version in all four surveys. Age, gender, educational status, prior experience of using a tablet PC, and the order of paper to tablet PC administration did not impact patient preferences. Inter-class correlation coefficients (ICCs) between the modes were 0.92 for MDASI-K and 0.94 for BFI-K and ranged from 0.91 to 0.96 on both instruments during the four surveys.
Conclusions
A tablet PC-based PRO is an acceptable and reliable method compared with paper-based data collection for Korean patients receiving radiotherapy.
