RESUMO
BACKGROUND: The increasing pressure of their professional duties has led to a notable concern regarding the mounting anxiety levels among nurses. The ongoing discussion revolves around the efficacy of mindfulness as a means to alleviate anxiety in nurses. AIM: This systematic review evaluated the effectiveness of mindfulness in reducing anxiety among nurses. METHODS: The evaluation followed the guidelines of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses. An extensive and comprehensive search was conducted across eight databases to identify studies that utilized randomized controlled trials (RCTs) and were published in English between 2011 and 2022. Independently, two reviewers assessed the validity of the randomized controlled trials using the Consolidated Standards of Reporting Trials criteria. Additionally, two authors independently employed the Risk of Bias in Non-Randomized Studies of Interventions (ROBINS-2) method to evaluate the potential bias in the RCTs. RESULTS: Eight randomized controlled trial studies that were deemed eligible were included in the current analysis. Based on the literature review, it was determined that mindfulness-based training can assist nurses in reducing their anxiety levels. Furthermore, the effectiveness of mindfulness-based programs in enhancing nurses' mindfulness and self-compassion has been firmly established. CONCLUSIONS: Based on existing literature, mindfulness-based interventions have proven to be effective in reducing anxiety levels among nurses. However, in order to enhance the overall quality of research, it is necessary to implement more rigorous controlled designs that include randomization. Additionally, larger sample sizes with a diverse range of participants are needed to establish and validate the effectiveness of mindfulness-based programs in alleviating anxiety among nurses. LINKING EVIDENCE TO ACTION: Implementing mindfulness-based training in healthcare organizations can offer numerous benefits. One such advantage is that it can help nurses in reducing anxiety and enhancing their ability to handle the pressures associated with their profession.
