Patient-reported outcome measures are a cornerstone of outcome assessment in orthopaedics. However, completing the pencil and paper questionnaires in clinic is something of a burden to the individual patient and the health care institution. We do not provide much in the way of incentives to collect PRO data. Lengthy questionnaires and hidden data analysis offer no direct benefit to the individual patient nor the clinician. Employing ePRO, utilising tablet PCs for questionnaire completion, can improve this situation considerably. Swift and cost-effective data management and instant availability of results using intuitive graphical display make questionnaire completion more rewarding. Direct feedback of PRO data during the consultation can inform the individual's care. Completing electronic questionnaires also makes computer-adaptive testing (CAT) possible. CAT creates dynamic questionnaires, adapting to the individual symptom burden of the individual patient. CAT both increases measurement precision and reduces the number of questions required. As such, ePRO assessment may help to maximise the efficiency and the utilisation of PRO data
