The Impact of Combined Mindfulness-Based Interventions and Nutritional Counseling on Physician Burnout: A Clinical Trial

There is a preponderance of data to support the detrimental effects of burnout on physicians' health and wellbeing. Physician burnout is defined as severe emotional exhaustion, depersonalization towards others and reduced sense of personal achievement. Burnout is often accompanied by feelings of moral distress, loss of interest and energy, and detachment from patients, colleagues and personal relatives. With the recent rapid expansion in global healthcare systems in response to societal changes, rates of physician burnout have been on the rise. It is estimated that 54% of physicians in the United States suffer from professional burnout, a 2-fold higher prevalence than that estimated for the general working population of 28%.

Burnout has serious negative implications on the physical health and wellbeing of individuals. In recent studies, burnout was associated with higher incidence of coronary heart disease and hospitalization from cardiovascular causes. Additionally, burnout was found to be an independent risk factor for type 2 diabetes mellitus and hypercholesterolemia (total cholesterol ≥220 mg/dl). Higher incidence of musculoskeletal pain and pain-related disability were also reported amongst subjects with high burnout. Excessive fatigue, insomnia, headaches, gastrointestinal and respiratory issues were all positively correlated with burnout level. More strikingly, burnout was found to be a significant predictor of mortality in those below the age of 45-years.

Burnout carries its repercussions on mental health as well. In a study of 2,555 dentists, burnout was a significant predictor of depression occurrence during the 3-year follow-up period. Increased psychotropic and antidepressant use was associated with high burnout, with a stronger correlation observed for men than women. High level of burnout was also linked to increased risk of anxiety, substance abuse, alcohol abuse, and even suicidal ideation.

Burnout is a serious threat to the medical profession at large. With more than half of the US physicians suffering from professional burnout, its implications ripple through the entirety of the healthcare system. Burnout decreases both patient care quality and physician productivity. Increased sickness absences have been reported in high burnout. In a recent report, severe burnout independently accounted for 52 sickness absences in a 2-year follow-up period. Additionally, burnout has resulted in more physicians leaving practices or reducing their work hours. A healthcare system loses on average $500,000 to $1,000,000 with the departure of a physician, in addition to the ever-increasing workload of physicians who remain in practice. Most significant of all, burnout leads to major medical errors. With the estimated 250,000 deaths in the United States occurring due to medical errors, developing effective strategies to eliminate physician burnout has become an ever-present priority.

A number of prospective studies and clinical trials have been conducted to assess the efficacy of different interventions on mitigating physician burnout. A major cluster of these studies have focused on behavioral interventions, more specifically, mindfulness-based approaches aimed at reducing the mental and emotional repercussions of burnout. Such behavioral interventions included practices of contemplation-meditation exercises, discussions on enhancing self-care and intensification of present-moment awareness. Efficacy in the latter studies was mostly assessed via quantification of change in burnout and stress-related scores, most notably the Maslach Burnout Inventory score, a well-established tool for assessment of burnout in the occupational setting. The majority of these studies reported favorable effects on burnout scores. However, limited to no-data exist on the physiological and biochemical effects of mindfulness-based interventions on physician burnout.
