QualFatigue study: which factors influence the use of specific interventions for breast cancer survivors with fatigue? A cross-sectional exploratory study

International guidelines recommend specific interventions to reduce cancer-related fatigue (CRF). Evidence suggests underutilization of these interventions among breast cancer survivors. The QualFatigue study aimed to explore the potential factors influencing the use of specific interventions, for relief, in patients with CRF through qualitative analyses. Patients with stage I–III breast cancer, and CRF ≥4 on a 10-point numerical scale were recruited within 6–24 months at the end of their primary treatment. Semi-structured interviews were performed. Emergent themes were identified using a stepped content analysis (QDA Miner software). Data saturation was achieved with 15 interviews. Four main themes emerged as potential sources of influence in the participants’ use of specific interventions: (1) expectations regarding the management of CRF, (2) representations of the benefits provided by the interventions, (3) individual physical and psychological conditions, and (4) social and environmental situations. Six key levers came out transversally to optimize the use of specific interventions to relieve CRF: (1) listening and recognition of the individual difficulties and needs; (2) individual and global health assessments; (3) information and advice on how to manage CRF; (4) discussion groups focused on the management of CRF; (5) group activities; and (6) professional and personalized guidance. This study calls for multi-level action to address many persistent barriers and exploit levers in the management of CRF.
