Psychological mobile app for patients with acute myeloid leukemia: A pilot randomized clinical trial

Abstract

Background: Patients with acute myeloid leukemia (AML) experience a substantial decline in quality of life (QoL) and mood during their hospitalization for intensive chemotherapy, yet few interventions have been developed to enhance patient-reported outcomes during treatment.

Methods: We conducted a pilot randomized trial (ClinicalTrials.gov identifier NCT03372291) of DREAMLAND, a psychological mobile application for patients with a new diagnosis of AML who are receiving intensive chemotherapy. Patients were randomly assigned to DREAMLAND or usual care. DREAMLAND included four required modules focused on: (1) supportive psychotherapy to help patients deal with the initial shock of diagnosis, (2) psychoeducation to manage illness expectations, (3) psychosocial skill-building to promote effective coping, and (4) self-care. The primary end point was feasibility, which was defined as ≥60% of eligible patients enrolling and 60% of those enrolled completing ≥60% of the required modules. We assessed patient QoL (the Functional Assessment of Cancer Therapy-Leukemia), psychological distress (the Hospital Anxiety and Depression Scale and the Patient Health Questionnaire-9), symptom burden (the Edmonton Symptom Assessment Scale), and self-efficacy (the Cancer Self-Efficacy Scale) at baseline and at day 20 after postchemotherapy.

Results: We enrolled 60 of 90 eligible patients (66.7%), and 62.1% completed ≥75% of the intervention modules. At day 20 after chemotherapy, patients who were randomized to DREAMLAND reported improved QoL scores (132.06 vs. 110.72; p =.001), lower anxiety symptoms (3.54 vs. 5.64; p = .010) and depression symptoms (Hospital Anxiety and Depression Scale: 4.76 vs. 6.29; p = .121; Patient Health Questionnaire-9: 4.62 vs. 8.35; p < .001), and improved symptom burden (24.89 vs. 40.60; p = .007) and self-efficacy (151.84 vs. 135.43; p = .004) compared with the usual care group.

Conclusions: A psychological mobile application for patients with newly diagnosed AML is feasible to integrate during hospitalization for intensive chemotherapy and may improve QoL, mood, symptom burden, and self-efficacy.
