Data collection methods for patient-reported outcome measures in cancer randomised controlled trials: a protocol for a rapid scoping review.

The proposed review is based on secondary, published data. Hence, no ethics review is necessary. The review is part of an ongoing project on the use of electronic data capture methods in cancer clinical trials. The findings from the review will support the project and contribute to synthesising guidance to ultimately improve the (electronic) measurement of patient-reported outcome measures in clinical trials.
