Patient-Reported Distress and Acute Care Utilization for Cervical Cancer Patients Undergoing Concurrent Chemoradiation

Abstract

Although concurrent chemo-radiation (CRT) and brachytherapy (BT) is curative for locally advanced cervical cancer (LACC), it requires complex coordination of care and is associated with treatment-related toxicity. Our objective was to evaluate patient-reported symptoms and social distress in LACC patients undergoing concurrent CRT and BT to determine whether they are predictive of unplanned acute care utilization. Patients with LACC treated with concurrent CRT and BT between 2013-2020 completed the Edmonton Symptom Assessment Scale-revised (ESAS-r; 9 cancer-related symptoms ranked 0-10) and the Social Difficulties Inventory-21 (SDI-21; 21 social issues ranked 0-3) at every visit as part of routine distress screening. Acute care utilization was defined as any unplanned visit to the radiation nursing clinic, urgent care clinic, emergency department or hospitalization within 1 year from starting treatment. A logistic regression model will be used to evaluate associations between ESAS-r and SDI-21 scores and acute care utilization. Among 151 LACC patients, a total of 354 ESAS-r and SDI questionnaires were completed longitudinally. Mean age at diagnosis was 49.9 years (30-90), 44% were FIGO 2B and overall treatment time was 53.6 days (32-135). At baseline, the most prevalent moderate to severe symptoms (ESAS-r score ≥4) were well-being (50%), anxiety (44%), tiredness (43%) and pain (36%). Post-treatment, these persisted in 42%, 27%, 38%, and 26%, respectively. The most common social distress at baseline was financial (33%). Financial distress post-treatment was significantly predictive of worse well-being (OR = 5.80, p<0.06), anxiety (OR = 3.33, p<0.04) and depression (OR = 4.76, p<0.01). Use of acute care within 1 year after starting treatment occurred in 103 patients (68%) for a total of 617 visits: radiation nursing clinic 71.3%, urgent care clinic 4.4%, emergency department 8.3%, hospitalization 16%. On average there were 6.6 visits/patient (0-31), with the average number of days between treatment start and first acute care visit being 17.9 (0-74). Cervical cancer patients undergoing concurrent CRT report prevalent financial distress and moderate to severe symptoms that persist post-treatment. Acute care utilization commonly occurred during treatment, highlighting a time when additional support is needed. Predictive modelling for distress factors resulting in acute care utilization is now underway.
