Study within a trial of electronic versus paper-based Patient-Reported oUtcomes CollEction (SPRUCE): study protocol for a partially randomised patient preference study

Introduction
Patient-reported outcomes (PRO) are currently collected from trial participants using paper questionnaires by the Clinical Trials and Statistics Unit at The Institute of Cancer Research (ICR-CTSU). Streamlining PRO collection using electronic questionnaires (ePRO) may improve data collection and patient experience. Here, we outline our protocol for a Study within a trial of electronic versus paper-based Patient-Reported oUtcomes CollEction (SPRUCE), which investigates the acceptability of ePRO in oncology clinical trials.

Methods and analysis
SPRUCE was developed alongside patient and public contributors. SPRUCE runs in multiple host trials with a partially randomised patient preference design, allowing participants to be randomised or choose their preference of electronic or paper questionnaires. Questionnaires are scheduled in accordance with host trial follow-up. The primary objective will assess differences in return rates (compliance) between ePRO and paper PROs at the first timepoint post-host trial intervention in the randomised group. Paper PRO compliance is expected to be 90%. 244 randomised participants are required to exclude ≤80% compliance rates with ePRO (10% non-inferiority margin, with 80% power and one-sided alpha=0.05). SPRUCE aims to assess acceptability of ePRO in oncology clinical trials, establish whether ePRO is acceptable to ICR-CTSU trial participants and can capture complete PRO data, consistent with paper PROs.

Ethics and dissemination
The SPRUCE protocol (ICR-CTSU/2021/10074) was approved by the Coventry and Warwick Central Research Ethics Committee (21/WM/0223) on 21 October 2021. Results will be disseminated via presentations, publications and lay summaries. No participant identifiable data will be included.
