Nursing practice in cancer treatment decision making among older adults: A scoping review on behalf of the International Society of Geriatric Oncology Nursing, Allied Health, and Scientists Interest Group.

[INTRODUCTION] Cancer treatment decision making (CTDM) presents important challenges among older adults due to variation in health and functional status, presence of comorbidities, differing goals/values, quality and quantity of life considerations, and limited inclusion in clinical trials. Nursing standards and guidelines call for competence in supporting CTDM and nurses advocate for greater involvement. However, clear understanding of the existing evidence to inform nursing practice is lacking. We aimed to map and synthesize evidence that provides insight into nursing practice in CTDM among older adults, with attention to nursing roles, required skills and competencies, potential barriers and facilitators, and outcomes studied.

[MATERIALS AND METHODS] Following JBI (formerly Joanna Briggs Institute) methodology for scoping reviews, we included empirical articles that describe nursing contribution, individually or as part of a multidisciplinary team (MDT), related to CTDM for active (curative or non-curative) treatment among adults aged ≥60 years diagnosed with cancer. Nine databases were searched systematically from inception to January 2024, no limits applied. Two independent reviewers screened identified records and full texts, then systematically extracted data from included articles. Basic qualitative content analysis was conducted on charted data.

[RESULTS] Of the 9582 records screened, 980 full texts were assessed for eligibility; 84 reports describing 78 studies were included. Conducted primarily in the United States or United Kingdom, studies described nursing interventions, nursing involvement in geriatric assessment and MDT meetings/clinics, and the perspectives of patients, family, and/or healthcare professionals. Although seldom the primary focus, researchers have highlighted the important roles of nurses in the CTDM process, before, during, and after consultations with physicians and MDT meetings, which require disease-specific knowledge and relational skills. MDT collaboration, training, dedicated time and space, adequate resources, and support from leadership are critical to promoting involvement, with potential impact on decision satisfaction and optimal treatment decisions. The value of nurses' involvement is endorsed by patients, family, and other healthcare professionals.

[DISCUSSION] Nurses play a vital role in CTDM among older adults, particularly in the MDT context. However, rigorous studies demonstrating the impact of nursing practice on CTDM outcomes among older adults are lacking. Further research is needed to inform nursing practice and interventions.
