Device and Data Access Considerations for Digital Health Studies Using Consumer-Grade Wearables: An Experience-Based Tutorial.

Emergency departments are clinical settings characterised by high levels of work demand due to unpredictable patient numbers, traumatic cases and exposure to violence. Previous studies have shown that nurses working in high‐risk units such as emergency departments are frequently exposed to verbal and physical violence, and that workplace violence has a significant impact on emotional labour and intention to leave the job [–]. Furthermore, high workload and traumatic exposure have been reported to increase burnout, and burnout has been shown to increase intention to leave []. These conditions create a significant cognitive and emotional burden on nurses [, ]. Nurse retention is influenced by a complex interplay of organisational, psychological and work‐environment factors, and evidence suggests that these determinants are particularly salient in high‐pressure clinical settings such as emergency departments []. Therefore, it is important for nurses to be able to use high levels of cognitive control and cognitive flexibility to protect their mental and physical health []. Cognitive flexibility and cognitive control refer to the mental processes that enable individuals to focus their attention, suppress impulsive responses and adapt to rapidly changing situations [, ]. Within the framework of the Job Demands‐Resources (JD‐R) Model, these capacities function as personal psychological resources that buffer the adverse effects of high job demands, sustain adaptive coping and support the regulation of impulsive emotional responses []. When cognitive control is weak, individuals may exhibit increased impulsive behaviour, which can make it difficult to regulate emotional responses []. These skills are critical for effective decision‐making and adaptation, particularly in complex and uncertain environments []. In high‐stress work environments where workplace violence occurs, insufficient cognitive capacity can lead to increased levels of anger and its expression in dysfunctional ways [, ]. The uncontrolled expression or suppression of anger can negatively affect interpersonal relationships and lead to reduced job satisfaction and resignations [–]. Developing strategies to retain emergency nurses is a critical necessity for the sustainability of the healthcare system. The increased burnout and intention to leave the profession, particularly after Covid‐19, has exacerbated the shortage of nurses globally []. In Turkey, the number of nurses is also quite low compared to OECD countries, with approximately 3 nurses per 1000 people []. Therefore, ensuring the retention of nurses in units with high workloads and intense stress levels, such as emergency departments, is of great importance.
