Nurse Coaching in Oncology Care to Reduce Stress: A Systematic Review and Meta-Analysis

Background: Nurse coaching can reduce stress throughout the complex psychosocial process associated with the cancer journey, which affects numerous spheres, such as neurological, psychological, physical, and emotional ones. The purpose of this paper is to review the literature to assess the extent of stress reduction among cancer care adopting nurse coaching interventions. Methods: This systematic review and meta-analysis was registered in PROSPERO with id no. CRD420261290368 and performed according to the Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) guidelines. The search approach was performed by mixing keywords with Boolean operators like "coaching intervention", "oncology nursing" and "stress" throughout the CINAHL, Embase, PubMed, Scopus and Web of Science databases. We assessed stress levels alongside the nurse coaching interventions using the National Comprehensive Cancer Network (NCCN) Distress Thermometer. Results: A total of three studies were included, comprising 112 participants. Heterogeneity among studies was very high and statistically significant (p < 0.001; τ² = 1.02; I² = 96.2%, with a 95% CI: [85.89; 99.90]); thus, a random-effects model (REML) was applied. A small, non-significant reduction in stress levels following the nurse coaching intervention, with an overall SMD of -0.35 (SE = 0.60; 95% CI: [-1.52, 0.82]; p = 0.556), was recorded. Conclusions: Attention to standardization of core coaching components, while preserving flexibility and personalization, will be critical to advancing implementation in routine oncology care. Overall, nurse coaching represents a promising adjunct to comprehensive cancer care, with the potential to support psychological well-being, empower patients and caregivers, and address the broader determinants of stress throughout the cancer experience.
