Coaching Ongoing Momentum Building On stroKe rEcovery journeY ('COMBO-KEY'): a randomised controlled trial protocol

Systematic reviews reporting self-management interventions are associated with significant improvements in stroke survivors' self-efficacy, health-related quality of life (HRQoL) and independence. However, common barriers such as transportation and availability of carers were identified. Health coaching is suggested as an innovative and cost-effective care model with potential benefits in managing chronic diseases. A randomised controlled trial is proposed to evaluate the effectiveness of an enhanced self-management programme by health coaches on stroke survivors' recovery outcomes.

All adult community-dwelling stroke survivors with a modified Rankin Scale Score ≥3 will be recruited from a community rehabilitation network. Eligible participants will be randomly allocated to receive either the enhanced stroke self-management programme (Coaching Ongoing Momentum Building On stroKe rEcovery journeY [COMBO-KEY]) plus usual care or usual care only. COMBO-KEY is an 8-week programme underpinned by Bandura's principles of self-efficacy and outcome expectation. It consists of four home visits and five phone-coaching sessions delivered by trained health coaches. Each participant will receive a resource package containing a workbook, a quick reference guide, a planning toolkit and 15 videos of peer survivors' stroke survival experience. Survivors' outcomes include self-efficacy, outcome expectation and satisfaction with performance of self-management behaviours, HRQoL, depressive symptoms and community reintegration. Assessment will be conducted at baseline and immediately after completing the programme. Generalised estimating equations' model will be used to analyse the data.

It is anticipated that the programme will build community capacity in supporting stroke survivors. The results will shed light on integrating the programme into the current stroke rehabilitation services.

The Joint Chinese University of Hong Kong-New Territories East Cluster Clinical Research Ethics Committee has approved this protocol (CREC Ref. No.: 2018.009). Written informed consent will be obtained from all participants. Study results will be disseminated through peer-reviewed journals and presentations at local and international conferences.
