| Abstract |
Importance: Physicians are exposed to high stress and strain that results in burnout, which affects them, their families, their patients, and the entire health care system; thus, there is an urgent need to develop methods to increase the resiliency of physicians. Sudarshan Kriya Yoga (SKY) is a comprehensive yoga breathing and meditation-based program that is a potential approach to mitigate physician burnout.
Objective: To determine whether SKY can reduce psychological distress and improve wellness in physicians.
Design, setting, and participants: This randomized clinical trial assessed the potential efficacy of SKY compared with a stress management education (SME) training as control. This study was conducted online from November 11, 2021, to March 14, 2022, and included physicians from Turkey, Germany, and Dubai. Both the SKY and the SME control groups received 1.5 hours of training for 3 consecutive days via a group video conference call. Participants were physicians willing to do some form of relaxation exercise everyday for 2 months. Exclusion criteria included presence of major illness and maintaining a regular mind-body program practice. Statistical analysis took place from March to November 2023.
Interventions: Participants were randomly assigned 1:1 into 2 groups-the SKY group or the SME (control) group-using a computer algorithm. After the 3-day instruction period, the participants in the SKY group practiced for approximately 30 minutes per day on their own and participated in a weekly 1-hour, group-based online follow-up practice. After the 3-day instruction period, participants in the SME group reviewed and applied the notes from stress management education training at their initiative and had a weekly 1-hour group-based online follow-up session.
Main outcomes and measures: The primary outcomes were stress and depression (measured by the 42-item Depression, Anxiety, and Stress Scale [DASS-42]) and insomnia measured by the Regensburg Insomnia Scale (RIS) with primary end point at 8 weeks. Secondary outcomes included anxiety (DASS-42); optimism (Life Orientation Test-Revised [LOT-R]); professional fulfillment, work exhaustion, interpersonal disengagement, and overall burnout (Professional Fulfillment Index [PFI]); and self-reported professional errors (Self-Reported Professional Error Questionnaire).
Results: This study included 129 participants (SME, 63 participants [48.9%]; SKY, 66 participants [51.1%]; 115 females [89.2%]; 14 males [10.8%]; mean [SD] age, 46.2 [9.0] years). Compared with the SME control group, participants in the SKY group had significantly decreased stress on the DASS-42 at posttraining (difference, -6.8 points; 95% CI, -9.6 to -4.1 points; P = .006) and at postintervention (difference, -6.0 points; 95% CI, -8.8 to -3.3 points; P = .03), significantly decreased depression at posttraining (difference, -5.7 points; 95% CI, -8.6 to -2.8 points; P < .001) and postintervention (difference, -5.4 points; 95% CI, -8.3 to -2.5 points; P < .001), and significantly decreased anxiety at postintervention. In addition, there was a significant decrease in insomnia from baseline to postintervention in the SKY group (difference, -0.3 points; 95% CI, -2.3 to 1.7 points; P = .01). The SKY group also showed significantly increased professional fulfillment as well as significant decreases in work exhaustion, interpersonal disengagement, and burnout. There was no effect on self-reported medical errors.
Conclusions and relevance: In this randomized clinical trial, physicians who regularly practiced SKY throughout a 2-month period experienced improvements in wellness and decreased burnout. These data suggest that SKY may be an effective, practical, and safe strategy to increase wellness and mitigate burnout in physicians.
