The long-lasting relationship of distress on radiation oncology-specific clinical outcomes

Abstract

Purpose: The diagnosis and treatment of cancer can have significant mental health ramifications. The National Comprehensive Cancer Network currently recommends using a distress screening tool to screen patients for distress and facilitate referrals to social service resources. Its association with radiation oncology–specific clinical outcomes has remained relatively unexplored. Methods and materials: With institutional review board approval, National Comprehensive Cancer Network distress scores were collected for patients presenting to our institution for external beam radiation therapy during a 1-year period from 2015 to 2016. The association between distress scores (and associated problem list items and process-related outcomes) and radiation oncology–related outcomes, including inpatient admissions during treatment, missed treatment appointments, duration of time between consultation and treatment, and weight loss during treatment, was considered. Results: A total of 61 patients who received either definitive (49 patients) or palliative (12 patients) treatment at our institution and completed a screening questionnaire were included in this analysis. There was a significant association between an elevated distress score (7+) and having an admission during treatment (36% vs 11%; P = .04). Among the patients treated with definitive intent, missing at least 1 appointment (71% vs 26%; P = .03) and having an admission during treatment (57% vs 10%; P = .009) were significantly associated with our institutional definition of elevated distress. We found no correlation between distress score and weight loss during treatment or a prolonged time between initial consult and treatment start. Conclusions: High rates of distress are common for patients preparing to receive radiation therapy. These levels may affect treatment compliance and increase rates of hospital admissions. There remains equipoise in the best method to address distress in the oncology patient population. These results may raise awareness of the consequences of distress among radiation oncology patients. Specific interventions to improve distress need further study, but we suggest a more proactive approach by radiation oncologists in addressing distress.
