To examine factors influencing emergency nurse turnover and retention pre- and post-COVID-19 and inform planned Participatory Systems Mapping research.
A scoping review of the literature reporting reasons emergency nurses leave, intend to leave or stay.
Following the Joanna Briggs Institute methodology and a pre-registered protocol, databases and grey literature were systematically searched in January 2025 (updated August 2025). Literature published after 1st January 2010, was included. Two reviewers independently screened records, and 10% of extractions were cross-checked. Data were grouped thematically on a visual coding system using the Miro platform. Pre- and post-COVID-19 sources were categorised and analysed using a two-dimensional framework of intensity and frequency.
MedLine, CINAHL, PsycINFO, Web of Science, Cochrane and grey literature.
Ninety-three sources were included. Burnout, workload, staffing and workplace violence (WPV) were linked across study designs to turnover, while job satisfaction, supportive leadership and team cohesion appeared to support retention. Problem-focused and resilience-based coping were associated with retention across study designs (n = 5); emotion-focused strategies were linked with poorer outcomes (n = 3). In a subset of 86 sources, traditional protective factors (leadership support and team camaraderie) appeared weakened post-COVID-19. A novel theme of moral obligation to remain, despite personal risk, emerged. Adaptive coping gave way to downshifting and emotional suppression.
The included evidence indicates that multiple, interacting factors shape emergency nurse turnover and retention, whilst systemic strategies aligning operational demands with psychological safety and core nursing values may contribute to sustainable retention.
Workforce interventions should address the psychological legacy of COVID-19 and focus on rebuilding trust, flexibility and moral sustainability in emergency departments.
While individual drivers of turnover are known, their complex interplay and retention factors are underexplored. This review identifies themes transcending boundaries and recurring across the turnover pathway, underscoring the need for multi-level interventions relevant to both nurse managers and policy makers.
Reporting follows the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews guidelines (PRISMA-ScR).
This study did not include patient or public involvement in its design, conduct or reporting.
Current pharmacological treatment options for painful diabetic neuropathy (PDN) often fail to provide adequate pain relief. However, in the recent SENZA-PDN study, high-frequency 10 kHz spinal cord stimulation (SCS) demonstrated significant long-term improvements in lower limb pain and health-related quality of life (HRQoL) in a PDN population. Furthermore, more than half of 10 kHz SCS recipients showed improved sensory function based on non-blinded clinical assessments in post hoc analysis. We report the design of the PDN-Sensory study, which aims to evaluate changes in pain and neurological function with 10 kHz SCS in the treatment of PDN. The study will include objective measures of neurological function, including the modified Toronto Clinical Neuropathy Score (mTCNS) and intraepidermal nerve fibre density (IENFD).
This multicentre, prospective, randomised controlled trial will compare conventional medical management (CMM) with 10 kHz SCS+CMM in individuals with diabetes and chronic, intractable lower limb pain due to PDN. Participants will be randomised 1:1 to CMM alone or 10 kHz SCS+CMM, with optional crossover at 6 months. The primary outcome is the proportion of participants at 6 months achieving ≥50% pain relief from baseline. The key secondary endpoint is the proportion of participants at 6 months with a reduction in mTCNS of ≥3 points from baseline (excluding changes in foot pain). Additional endpoints at 6 and 12 months include changes from baseline in mTCNS, IENFD, 7-day averaged pain score, pain-related interference, HRQoL, sleep, psychological outcomes, functional status and metabolic parameters.
The study protocol received central approval from the Western Institutional Review Board (IRB #20230954). Local IRB approval will be required before initiation of the study at each participating clinical site. The study complies with Good Clinical Practice guidelines (ISO 14155), the Declaration of Helsinki, and all applicable national, federal and local regulatory requirements. Dissemination plans include presentations at national and international conferences and publication in a peer-reviewed journal with open access.
