The DISCO app: A pilot test of an electronic patient intervention to reduce the financial burden of cancer through improved cost communication.

Abstract

e24197 Background: Financial toxicity, the burden of treatment cost, affects 30-50% of people with cancer in the United States. Although experts recommend patients and oncologists discuss treatment cost to identify patients who need assistance, cost discussions occur in fewer than half of cancer treatment discussions. We pilot-tested the feasibility and efficacy of the Discussions of Cost (DISCO) App, a patient communication intervention designed to improve cost discussions and other financial toxicity-related outcomes during and following oncology treatment consultations. The DISCO App provides an individualized list of cost-related questions patients can ask their oncologist, specific to a patient’s economic situation. Methods: While waiting to see their oncologist, newly diagnosed patients with breast or lung cancer (n=32) used the DISCO App on an iPad. Clinic visits were videorecorded and patients completed pre- and post-intervention measures of self-efficacy for managing treatment costs, self-efficacy for interacting with oncologists, cost-related distress, and perceptions of the DISCO App. A trained coder observed the recordings to determine the presence of a cost discussion, the cost-related topic, and any emergent factors. Results: Findings showed increases in patients’ self-efficacy for managing treatment costs (p=.02) and interacting with oncologists (p=.001). Cost-related distress decreased but not significantly (p=.20). Patients reported the DISCO App was understandable (M=4.5 out of 5), useful as they talked with their oncologist (M=4.0), and 84% of patients reported needing less than 15 minutes to use the DISCO App. Most (94%) interactions were videorecorded (in two cases technical difficulties prevented videos from being collected); all (100%) of the videorecorded interactions included a cost discussion. The most frequently discussed topics were: insurance, time off from work, and financial navigation. Frequently, the oncologist asked the patient for his/her question list and discussed/answered the questions. Conclusions: Findings suggest the DISCO App is feasible to implement in the clinic and effective in improving patient-oncologist cost discussions and financial toxicity-related outcomes. Patient acceptance of the DISCO App and oncologist engagement suggested the intervention prompted cost discussions. Next steps include conducting a longitudinal randomized controlled trial to determine the effectiveness of the DISCO App on financial toxicity, and other outcomes.
