The acceptability of exercise prehabilitation before cancer surgery among patients, family members and health professionals: a mixed methods evaluation.

Purpose: Exercise prehabilitation aims to increase preoperative fitness, reduce post-operative complications, and improve health-related quality of life. For prehabilitation to work, access to an effective programme which is acceptable to stakeholders is vital. The aim was to explore acceptability of exercise prehabilitation before cancer surgery among key stakeholders specifically patients, family members and healthcare providers.

Methods: A mixed-methods approach (questionnaire and semi-structured interview) underpinned by the Theoretical Framework of Acceptability was utilised. Composite acceptability score, (summation of acceptability constructs and a single-item overall acceptability construct), and median of each construct was calculated. Correlation analysis between the single-item overall acceptability and each construct was completed. Qualitative data was analysed using deductive and inductive thematic analysis.

Results: 244 participants completed the questionnaire and n=31 completed interviews. Composite acceptability was comparable between groups (p=0.466). Four constructs positively correlated with overall acceptability: affective attitude (r=0.453), self-efficacy (r=0.399), ethicality (r=0.298) and intervention coherence (r=0.281). Qualitative data confirmed positive feelings, citing psychological benefits including a sense of control. Participants felt flexible prehabilitation program would be suitable for everyone, identifying barriers and facilitators to reduce burden.

Conclusion: Exercise prehabilitation is highly acceptable to key stakeholders. Despite some burden, it is a worthwhile and effective intervention. Stakeholders understand its purpose, are confident in patients' ability to participate, and regard it is an important intervention contributing to patients' psychological and physical wellbeing.

Implications: •Introduction should be comprehensively designed and clearly presented, providing appropriate information and opportunity for questions. •Programmes should be patient-centred, designed to overcome barriers and address patients' specific needs and goals. •Service must be appropriately resourced with a clear referral-pathway.
