In the current period of global public health crisis due to the COVID-19, healthcare workers are more exposed to physical and mental exhaustion - burnout - for the torment of difficult decisions, the pain of losing patients and colleagues, and the risk of infection, for themselves and their families. The very high number of cases and deaths, and the probable future "waves" raise awareness of these challenging working conditions and the need to address burnout by identifying possible solutions. Measures have been suggested to prevent or reduce burnout at individual level (physical activity, balanced diet, good sleep hygiene, family support, meaningful relationships, reflective practices and small group discussions), organizational level (blame-free environments for sharing experiences and advices, broad involvement in management decisions, multi-disciplinary psychosocial support teams, safe areas to withdraw quickly from stressful situations, adequate time planning, social support), and cultural level (involvement of healthcare workers in the development, implementation, testing, and evaluation of measures against burnout). Although some progress has been made in removing the barrier to psychological support to cope with work-related stress, a cultural change is still needed for the stigma associated with mental illness. The key recommendation is to address the challenges that the emergency poses and to aggregate health, well-being and behavioral science expertise through long term researches with rigorous planning and reporting to drive the necessary cultural change and the improvement of public health systems.

Burnout Among Healthcare Workers in the COVID 19 Era: A Review of the Existing Literature

Abstract Background Healthcare workers can suffer from work‐related stress as a result of an imbalance of demands, skills and social support at work. This may lead to stress, burnout and psychosomatic problems, and deterioration of service provision. This is an update of a Cochrane Review that was last updated in 2015, which has been split into this review and a review on organisational‐level interventions. Objectives To evaluate the effectiveness of stress‐reduction interventions targeting individual healthcare workers compared to no intervention, wait list, placebo, no stress‐reduction intervention or another type of stress‐reduction intervention in reducing stress symptoms. Search methods We used the previous version of the review as one source of studies (search date: November 2013). We searched the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, Embase, PsycINFO, CINAHL, Web of Science and a trials register from 2013 up to February 2022. Selection criteria We included randomised controlled trials (RCT) evaluating the effectiveness of stress interventions directed at healthcare workers. We included only interventions targeted at individual healthcare workers aimed at reducing stress symptoms. Data collection and analysis Review authors independently selected trials for inclusion, assessed risk of bias and extracted data. We used standard methodological procedures expected by Cochrane. We categorised interventions into ones that: 1. focus one’s attention on the (modification of the) experience of stress (thoughts, feelings, behaviour); 2. focus one’s attention away from the experience of stress by various means of psychological disengagement (e.g. relaxing, exercise); 3. alter work‐related risk factors on an individual level; and ones that 4. combine two or more of the above. The crucial outcome measure was stress symptoms measured with various self‐reported questionnaires such as the Maslach Burnout Inventory (MBI), measured at short term (up to and including three months after the intervention ended), medium term (> 3 to 12 months after the intervention ended), and long term follow‐up (> 12 months after the intervention ended). Main results This is the second update of the original Cochrane Review published in 2006, Issue 4. This review update includes 89 new studies, bringing the total number of studies in the current review to 117 with a total of 11,119 participants randomised. The number of participants per study arm was ≥ 50 in 32 studies. The most important risk of bias was the lack of blinding of participants. Focus on the experience of stress versus no intervention/wait list/placebo/no stress‐reduction intervention Fifty‐two studies studied an intervention in which one's focus is on the experience of stress. Overall, such interventions may result in a reduction in stress symptoms in the short term (standardised mean difference (SMD) ‐0.37, 95% confidence interval (CI) ‐0.52 to ‐0.23; 41 RCTs; 3645 participants; low‐certainty evidence) and medium term (SMD ‐0.43, 95% CI ‐0.71 to ‐0.14; 19 RCTs; 1851 participants; low‐certainty evidence). The SMD of the short‐term result translates back to 4.6 points fewer on the MBI‐emotional exhaustion scale (MBI‐EE, a scale from 0 to 54). The evidence is very uncertain (one RCT; 68 participants, very low‐certainty evidence) about the long‐term effect on stress symptoms of focusing one's attention on the experience of stress. Focus away from the experience of stress versus no intervention/wait list/placebo/no stress‐reduction intervention Forty‐two studies studied an intervention in which one's focus is away from the experience of stress. Overall, such interventions may result in a reduction in stress symptoms in the short term (SMD ‐0.55, 95 CI ‐0.70 to ‐0.40; 35 RCTs; 2366 participants; low‐certainty evidence) and medium term (SMD ‐0.41 95% CI ‐0.79 to ‐0.03; 6 RCTs; 427 participants; low‐certainty evidence). The SMD on the short term translates back to 6.8 fewer points on the MBI‐EE. No studies reported the long‐term effect. Focus on work‐related, individual‐level factors versus no intervention/no stress‐reduction intervention Seven studies studied an intervention in which the focus is on altering work‐related factors. The evidence is very uncertain about the short‐term effects (no pooled effect estimate; three RCTs; 87 participants; very low‐certainty evidence) and medium‐term effects and long‐term effects (no pooled effect estimate; two RCTs; 152 participants, and one RCT; 161 participants, very low‐certainty evidence) of this type of stress management intervention. A combination of individual‐level interventions versus no intervention/wait list/no stress‐reduction intervention Seventeen studies studied a combination of interventions. In the short‐term, this type of intervention may result in a reduction in stress symptoms (SMD ‐0.67 95%, CI ‐0.95 to ‐0.39; 15 RCTs; 1003 participants; low‐certainty evidence). The SMD translates back to 8.2 fewer points on the MBI‐EE. On the medium term, a combination of individual‐level interventions may result in a reduction in stress symptoms, but the evidence does not exclude no effect (SMD ‐0.48, 95% CI ‐0.95 to 0.00; 6 RCTs; 574 participants; low‐certainty evidence). The evidence is very uncertain about the long term effects of a combination of interventions on stress symptoms (one RCT, 88 participants; very low‐certainty evidence). Focus on stress versus other intervention type Three studies compared focusing on stress versus focusing away from stress and one study a combination of interventions versus focusing on stress. The evidence is very uncertain about which type of intervention is better or if their effect is similar. Authors' conclusions Our review shows that there may be an effect on stress reduction in healthcare workers from individual‐level stress interventions, whether they focus one's attention on or away from the experience of stress. This effect may last up to a year after the end of the intervention. A combination of interventions may be beneficial as well, at least in the short term. Long‐term effects of individual‐level stress management interventions remain unknown. The same applies for interventions on (individual‐level) work‐related risk factors. The bias assessment of the studies in this review showed the need for methodologically better‐designed and executed studies, as nearly all studies suffered from poor reporting of the randomisation procedures, lack of blinding of participants and lack of trial registration. Better‐designed trials with larger sample sizes are required to increase the certainty of the evidence. Last, there is a need for more studies on interventions which focus on work‐related risk factors.

Individual‐level interventions for reducing occupational stress in healthcare workers

Yoga has been prevalent for over 5000 years; it originated in India and has become an essential lifestyle ingredient for achieving optimal health. The goal of this article in lifestyle modification is to increase awareness about the benefits of yoga and how its practice can reduce the overall risk of chronic diseases. Yoga has been proven to be therapeutic for enhancing immunity and support management of chronic diseases such as cardiovascular, respiratory, endocrine disorders, obesity, cancer, and metabolic syndrome. Yoga techniques called asanas, such as pranayama for breathing regulation and dhyana for meditation, boost innate immune response, interrupt inflammation, and thereby prevent the manifestation of chronic diseases. Yoga also provides symptomatic relief for chronic arthritis by increasing joint flexibility and microcirculation. Yoga and meditation regulate neurotransmitters, neuropeptides, hormones, and cytokines that mediate interactions between the central nervous system and the immune system. These techniques reduce the psychological and physiological effects of chronic stress. Serotonin, oxytocin, and melatonin released directly due to practicing yoga have been shown to better manage anxiety and fear, especially during the pandemic. We believe the current trends of chronic disease management will become more effective with the implementation of lifestyle changes using yoga.

Yoga for Preventive Health: A Holistic Approach

ABSTRACT This study aims to examine the impact of healthcare workers’ job stress (JS) from fear of COVID-19 (FC) on travel intentions (TI) and willingness to pay (WTP). It also investigates the direct path between FC and WTP. Moreover, it tests the moderation role of FC on the relationship between healthcare workers’ JS and TI. Partial Least Squares Structural Equation Modelling (PLS-SEM) was employed to analyze the data gathered from 401 frontline registered nurses working in pandemic hospitals in Turkey. The findings revealed that healthcare workers have the intention to travel and are willing to pay more for additional safety measures. The findings also indicated that FC negatively moderates the link between JS and TI. The results of this study provide theoretical and practical implications for tourism practitioners and marketers.

According to studies, occupational stress is quite prevalent among Emergency Medical Technicians (EMTs). On the other hand, it has been shown that Stachys lavandulifolia, also known as the Mountain Tea in Iran, has anxiolytic properties. Considering the current increasing trend of using remedies based on alternative medicine for stress management, the present clinical trial intended to investigate the effect of Stachys lavandulifolia on occupational stress in EMTs METHODS: The present study included 60 EMTs working in Arak, Markazi province, Iran, who were randomly divided into study and control groups. The study group was treated with tea made of Stachys lavandulifolia (2 g daily) for 2 months, while the control group was treated with black tea. Moreover, the level of occupational stress in the study participants was assessed using the Hospital Stress Scale (HSS-35) before and after the intervention. Data analysis was performed using the SPSS software version 22.According to our results, the mean occupational stress score was significantly decreased in the study group after the intervention (p < 0.05). Moreover, the post-intervention scores were significantly lower in the study group compared to the control group (p < 0.05). However, there was no significant change in occupational stress in the control group after the intervention (p > 0.05).In combination with other stress-relieving options, the tea made of Stachys lavandulifolia can be used as a complementary therapy for alleviating occupational stress in EMTs.

OBJECTIVES: Work related stress is a major occupational health problem that is associated with adverse effects on physical and mental health. Healthcare workers are particularly vulnerable in the era of COVID-19. Physical methods of stress relief such as yoga and massage therapy may reduce occupational stress. The objective of this systematic review and network meta-analysis is to determine the effects of yoga, massage therapy, progressive muscle relaxation, and stretching on alleviating stress and improving physical and mental health in healthcare workers. METHODS: Databases were searched for randomized controlled trials on the use of physical relaxation methods for occupational stress in healthcare workers with any duration of follow-up. Meta-analysis was performed for standard mean differences in stress measures from baseline between subjects undergoing relaxation vs non-intervention controls. Network meta-analysis was conducted to determine the best relaxation method. RESULTS: Fifteen trials representing 688 healthcare workers were identified. Random-effects meta-analysis shows that physical relaxation methods overall reduced measures of occupational stress at the longest duration of follow-up vs baseline compared to non-intervention controls (SMD -0.53; 95% CI [-0.74 to -0.33]; p < .00001). On network meta-analysis, only yoga alone (SMD -0.71; 95% CI [-1.01 to -0.41]) and massage therapy alone (SMD -0.43; 95% CI [-0.72 to -0.14]) were more effective than control, with yoga identified as the best method (p-score = .89). CONCLUSION: Physical relaxation may help reduce occupational stress in healthcare workers. Yoga is particularly effective and offers the convenience of online delivery. Employers should consider implementing these methods into workplace wellness programs.
