Self-reported overall wellbeing (OWb), physical function (PFn), and PRO-CTCAE symptom scores in post-operative and chemotherapy patients.

Abstract

2064 Background: A standardized, validated tool for capturing symptoms from cancer patients, PRO-CTCAE, has been used to reduce symptom burden, decrease acute care needs, and preserve quality of life. The association between specific PRO-CTCAE symptom scores and single item measures of OWb and PFn were characterized to understand symptom constellations. Methods: A novel Epic-based symptom management program (eSyM) was deployed for GI, GYN, and thoracic cancer patients starting chemotherapy (Memphis Baptist) or having surgery (WVU Medicine). Patients received automated prompts to complete surveys via the patient portal (MyChart) on a fixed schedule, approximately twice/week. Each survey included one OWb item, one PFn item, and at least 6 PRO-CTCAE items (pain, nausea, vomiting, fatigue, anxiety, insomnia). The OWb and PFn items, which were created de novo, included 5 ordinal response options with corresponding pictograms (emojis from very happy to very sad for OWb; a figure walking to one prone in bed for PFn). Composite scores were generated: 0 for no symptoms, 1-2 for mild/moderate symptoms, and 3 for severe symptoms. We describe OWb and PFn and analyze associations between these items and PRO-CTCAE symptom scores. Results: Between 9/10/19-1/22/20, we collected 908 eSyM responses from 166 chemotherapy patients at Baptist (Age, M = 65), and 480 eSyM responses from 97 postoperative patients at WVU (Age, M = 57). The OWb and PFn scores demonstrated moderate correlation with PRO-CTCAE symptom scores (Baptist r = 0.63; WVU r = 0.75), and moderate correlation with mean symptom scores among surgery patients at WVU (r = 0.74); but lower correlation among chemotherapy patients at Baptist (r = 0.53-0.55). Scores improved over time following surgery, but not after initiation of chemotherapy. Among the 730 eSyM responses with none/mild values for both OWb and PFn (52.9% of all responses), only 4.5% reported any severe symptom; among 651 responses with impairment of OWb and/or PFn, 45.2% reported at least one severe symptom. Conclusions: Integration of eSyM into the Epic EHR enabled tracking of OWb, PFn, and PRO-CTCAE items. When asked alongside PRO-CTCAE symptom items, two single item OWb and PFn measures provided distinct information and correlated with symptom burden. These results demonstrate the feasibility of integrating ePRO collection into routine post-operative and medical oncology care and that PRO-CTCAE items provide information that is distinct from that obtained from global metrics of well-being.
