Background: Working as nurses, the professional staff sometimes has to cope with very high levels of stress, which might result in the well-known burnout, anxiety, and depression. COVID-19 pandemic represents an additional constraint in nurses´ lives that emphasizes the role of mindfulness - oriented interventions in support of nurses´ well-being. On the other hand, the evidence obtained from previous studies on the impact of this kind of approaches have been much disagreement.

Methods: This deficit is overcome when researchers employ systematic reviews of RCTs that investigate the influence of mindfulness practices on nursing professionals. They run many databases and filter all the needed works, published until December 2022, with inclusion criteria in mind. Studies were selected for eligibity and data collected by a team of two independent researchers who assessed them for bias. The data which were collected were processed using designated soft wares.

Results and Discussion: In all, there were 44 records of 2171 studies to be analyzed. 15 of which were selected, recruiting a total of 1165 participants. The analysis indicates that mindfulness practice is a moderate stress reliever among nurses considering that the SMD is at -0.81, with a 95% CI of -1.11 to -0.52.

Conclusions: Mindfulness-based interventions are shown to be empirically valuable in the reduction of stress for nurses during the Covid-19 pandemic, which should be implemented extensively. But still, more studies should be done to reveal their connection to anxiety and other effects, and better be able to establish the level of security in the evidence.
