Patient preference attributes in eHealth interventions for cancer related fatigue: A scoping review

Introduction
Cancer-related fatigue (CRF) is one of the most reported long-term effects breast cancer patients experience after diagnosis. Many interventions for
CRF are effective, however, not for every individual. Therefore, intervention advice should be adjusted to patients' preferences and characteristics. Our aim was to develop an overview of eHealth interventions and their (preference sensitive) attributes.

Methods
eHealth interventions were identified using a scoping review approach. Eligible studies included breast cancer patients and assessed CRF as outcome. Interventions were categorized as physical activity, mind–body, psychological, ‘other’ or ‘combination’. Information was extracted on various (preference sensitive) attributes, like duration, intensity, peer support and costs.

Results
Thirty-five interventions were included and divided over the intervention
categories. (Preference sensitive) attributes varied both within and between these
categories. Duration varied from 4 weeks to 6 months, intensity from daily to own pace. Peer support was present in seven interventions and costs were known for six.

Conclusion
eHealth interventions exist in various categories, additionally, there is much variation in (preference sensitive) attributes. This provides opportunities to
implement our overview for personalized treatment recommendations for breast cancer patients struggling with CRF. Taking into account patients' preferences and characteristics suits the complexity of CRF and heterogeneity of patients.
