Utilizing the patient-reported outcomes measurement information system (PROMIS) to assess quality of life among breast cancer patients at an academic center.

Abstract

e23171 Background: NCI PROMIS assesses physical, mental and social health across multiple health conditions. Despite interest in using PROMIS in oncology trials and clinical care, reference values in cancer are not well established. Methods: Electronic intake questionnaires assessing self-reported history and 8 PROMIS domains (depression, anxiety, fatigue, sleep-related impairment (SRI), sleep disturbance, cognitive function, applied cognition and physical function) are sent to all new patients (pts). 2886 pts with self-reported breast cancer completed the questionnaire/consented to research. PROMIS T-Scores were calculated using the Health Measures system. Results: For all domains except depression, cognitive function and applied cognition, pts had clinically meaningful ( > 3 point diff.) worse mean PROMIS scores than US means (50). Compared to stage 0-III, stage IV pts had worse scores for all assessed domains (p < 0.05). Among Stage IV pts < 49, QoL was significantly worse in 7/8 domains (see table). Across all age groups, there were significant differences in mean PROMIS scores for Stage IV pts in anxiety, depression, cognitive function and applied cognition (p < 0.05). Conclusions: PROMIS scores among pts indicate impaired QoL in multiple domains. These scores provide insight into the physical, mental and social health of our pts and can serve as robust estimates for breast cancer trials and clinical care. [Table: see text]
