Mindfulness training for healthcare professionals and trainees: A meta analysis of randomized controlled trials

Objective: Healthcare professionals (HCPs) experience a wide range of physical and psychological symptoms that can affect quality of patient care. Previous meta-analyses exploring mindfulness-based interventions (MBIs) for HCPs have been limited by their narrow scope regarding intervention type, target population, and/or measures, and reliance on uncontrolled studies; therefore, a more comprehensive and methodologically rigorous examination is warranted. This meta-analysis quantified the effectiveness of MBIs on distress, well-being, physical health, and performance in HCPs and HCPs-in-training. Method: RCTs examining the effect of meditation and MBIs on HCPs and HCPs-in-training were identified and reviewed. Two independent reviewers extracted data and assessed risk of bias. Results: Thirty-eight studies were included in the analyses (n = 2505; 75.88% female). Intervention had a significant moderate effect on anxiety (Hedge's g = 0.47), depression (Hedge's g = 0.41), psychological distress (Hedge's g = 0.46), and stress (Hedge's g = 0.52). Small to moderate effects were also found for burnout (Hedge's g = 0.26) and well-being at post-intervention (Hedge's g = 0.32). Effects were not significant for physical health and performance. Larger intervention effects on overall outcomes were found with HCPs (Hedge's g = 0.52), with Mindfulness-based Stress Reduction intervention (Hedge's g = 0.47), and inactive controls (Hedge's g = 0.36). Conclusions: Results suggest mindfulness-based interventions are effective in reducing distress and improving well-being in HCPs and HCP-ITs. Subgroup analyses suggest the importance of exploring potential participants' needs prior to selecting the type of mindfulness intervention. Future studies should assess changes in mindfulness and include active controls.
