Mobile Mindfulness for Psychological Distress and Burnout among Frontline COVID-19 Nurses: A Pilot Randomized Trial

Abstract

Rationale The coronavirus disease (COVID-19) pandemic exacerbated psychological distress and burnout in frontline healthcare workers. Interventions addressing psychological distress and burnout among these workers are lacking. Objectives To determine the feasibility and explore the impact of mobile mindfulness to treat psychological distress and burnout among nurses in frontline COVID-19 units. Methods We conducted a pilot randomized trial of 102 nurses working in COVID-19 units at a single hospital between May 2021 and January 2022. Participants were randomized to mobile mindfulness (intervention) or waiting list (control). The primary outcome was feasibility, assessed by comparing rates of randomization, retention, and intervention completion to predefined targets. Secondary outcomes were changes in psychological distress (Patient Health Questionnaire-9, General Anxiety Disorder-7, Perceived Stress Scale-4) and burnout symptoms (Maslach Burnout Inventory) after 1 month. Results We randomized 102 of 113 consented individuals (90%, target 80%), and 88 completed follow-up (86%, target 80%). Among 69 intervention participants, 19 completed ⩾1 mindfulness session per week (28%, target 60%), and 13 completed ⩾75% of mindfulness sessions (19%, target 50%). Intervention participants had greater decreases in Patient Health Questionnaire-9 scores than control subjects (difference in differences, −2.21; 95% confidence interval, −3.99, −0.42; P = 0.016), but the Maslach Burnout Inventory depersonalization scores decreased more in the control arm than in the intervention arm (difference in differences, 1.60; 95% confidence interval, 0.18, 3.02; P = 0.027). There were no other changes in emotional distress or burnout symptoms. Conclusions This trial of mobile mindfulness in frontline nurses met feasibility targets for randomization and retention, but participants had modest intervention use. Intervention participants had a reduction in depression symptoms, but not in burnout. Clinical trial registered with www.clinicaltrials.gov (NCT04816708).

A Pilot Feasibility Evaluation of a Heart Rate Variability Biofeedback App to Improve Self-Care in COVID-19 Healthcare Workers

“…In terms of engagement, our intervention performed comparatively or better than similar studies utilizing mindfulness-based apps (Pratt et al, 2023 ; Schuman et al, 2023 ). While we failed to reach our goal of 75% participants doing meaningful HRVB on most days (≥ 67%), 88% engaged in HRVB on 33% or more of the protocol days.…”

“…Moreover, 40% of the sample did meaningful HRVB on 75% or more of the days. This is favorable compared to another recent feasibility study of a mindfulness-based app for nurses during the pandemic where 19% (13/69) of the sample completed 75% or more of the daily sessions (Pratt et al, 2023 ). HRVB and other mindfulness-based apps may have great promise, but uptake is going to take strategic advancements on user experience to fully realize the potential health enhancing features of these technologies.…”

Mobile Mindfulness Intervention for Psychological Distress Among Intensive Care Unit Survivors

“…Few hospital-based interventions or postdischarge interventions have demonstrated efficacy within this population. While self-directed, highly automated mobile therapies could be readily scaled to overcome many care access barriers, it has been unclear whether there is a critical contribution of the human touch of trained personnel that would justify the additional cost based on clinical effects, adherence, or retention compared with technologies that include robust user engagement features.…”
