Optimizing NCCN distress thermometer use in real-world settings: a systematic review and thematic synthesis of the literature.

PURPOSE

This systematic review aims to examine the workflows in distress screening and referral using the NCCN distress thermometer (DT) in the US, aiming to identify key elements for flexible, organization-specific approaches.

METHODS

A systematic review of full-text manuscripts published from 2013 to May 2024 was conducted using MEDLINE, EMBASE, and CINAHL. Studies describing distress screening and referral protocols were included, while systematic reviews, commentaries, non-US studies, non-English publications, and studies on distress score-disease burden associations were excluded. Attributes of distress screening and referral pathways were extracted.

RESULTS

From an initial 1219 articles, 19 studies were included. Significant variability was observed in NCCN DT workflows, particularly in responder characteristics (e.g., cancer type, patient vs. caregiver). Nursing staff primarily administered screenings, varying by mode (paper vs. electronic), frequency, and location (home vs. clinic). A cut-off score of 4 or higher often triggered referrals, with some studies further stratifying distress levels for tailored follow-ups. Referral pathways included educational resources, behavioral and emotional health, social support, and rehabilitative and supportive care services. Caregiver distress screening was infrequent.

CONCLUSION

This review underscores the variability in NCCN DT workflows and the need for customizable protocols. While standardization is desirable, some variation is essential to accommodate the differing availability of resources and personnel for effective distress screening and referral.

IMPLICATIONS FOR CANCER SURVIVORS

Effective distress screening and referral pathways ensure survivors receive timely psychological, emotional, and social support, improving quality of life. Integrating caregiver distress screening into workflows could amplify overall support systems, fostering holistic survivorship care. A flexible yet structured approach enhances access to tailored interventions, promoting resilience in survivors and caregivers.
