Need for recovery amongst emergency physicians in the UK and Ireland: A cross-sectional survey

OBJECTIVES: To determine the need for recovery (NFR) among emergency physicians and to identify demographic and occupational characteristics associated with higher NFR scores. DESIGN: Cross-sectional electronic survey. SETTING: Emergency departments (EDs) (n=112) in the UK and Ireland. PARTICIPANTS: Emergency physicians, defined as any registered physician working principally within the ED, responding between June and July 2019. MAIN OUTCOME MEASURE: NFR Scale, an 11-item self-administered questionnaire that assesses how work demands affect intershift recovery. RESULTS: The median NFR Score for all 4247 eligible, consented participants with a valid NFR Score was 70.0 (95% CI: 65.5 to 74.5), with an IQR of 45.5-90.0. A linear regression model indicated statistically significant associations between gender, health conditions, type of ED, clinical grade, access to annual and study leave, and time spent working out-of-hours. Groups including male physicians, consultants, general practitioners (GPs) within the ED, those working in paediatric EDs and those with no long-term health condition or disability had a lower NFR Score. After adjusting for these characteristics, the NFR Score increased by 3.7 (95% CI: 0.3 to 7.1) and 6.43 (95% CI: 2.0 to 10.8) for those with difficulty accessing annual and study leave, respectively. Increased percentage of out-of-hours work increased NFR Score almost linearly: 26%-50% out-of-hours work=5.7 (95% CI: 3.1 to 8.4); 51%-75% out-of-hours work=10.3 (95% CI: 7.6 to 13.0); 76%-100% out-of-hours work=14.5 (95% CI: 11.0 to 17.9). CONCLUSION: Higher NFR scores were observed among emergency physicians than reported in any other profession or population to date. While out-of-hours working is unavoidable, the linear relationship observed suggests that any reduction may result in NFR improvement. Evidence-based strategies to improve well-being such as proportional out-of-hours working and improved access to annual and study leave should be carefully considered and implemented where feasible

Bullying in Nursing: Is it in the Eye of the Beholder?

The nursing profession is presented with numerous definitions of workplace bullying. This study provides an in-depth analysis of the concept of bullying in the nursing profession in Australia through a scoping review of definitions presented in literature published up until 2018. The research questions used to guide the search were as follows: How has the definition of bullying in nursing in Australia been conceptualized in the literature? How do these definitions of bullying differ? How has the definition of bullying, as used in the literature, evolved over time? The review was informed by the approach of Arksey and O’Malley, containing explicit definitions of bullying in nursing literature. The findings reveal that the literature does not reflect a shared and integrated vision of the exact nature of bullying in the nursing profession. The conceptualization of bullying in the nursing profession has become more dynamic over time. The myriad ways in which bullying in nursing is defined in Australia has important implications for research, practice, education, and policy. </jats:p

Bullying in nursing: how has it changed over 4 decades?

Aim: This study sought to explore how bullying in the nursing profession in Australia has changed over four decades, and why it continues to persist. Background: Bullying in nursing is recognized as a pervasive problem. While much attention has been given to demonstrating the existence and impact of bullying in the nursing profession, little is understood about the evolution of this phenomenon and factors that contribute to its persistence. Methods: This study employed an historical methodology using the testimony method of data collection. Testimonies were collected online and via interview from seventy registered nurses across Australia. Data were analysed using a three-dimen- sional analysis to produce a chronological historiography. Results: This study found that the antecedents, manifestations, responses to and impacts of bullying in the nursing profession changed according to context and over time. The findings shed light on the role of nurse managers in the prevention and ap- propriate management of bullying in the workplace. Conclusion: Prevention and intervention approaches must be developed to combat the complex and changing factors that allow bullying to persist. Implications for Nursing Management: This study shows the role that management plays in tackling the problem of bullying in nursing. It can no longer be acceptable for culture to be used as an excuse for unacceptable behaviour, nor for power to be abused to protect perpetrators of workplace bullying. The findings discussed in this paper reveal that inexperienced nurse managers are often ill-equipped to identify and manage bullying. Nurses in management positions must recognize and acknowl- edge this deficit if the problem of bullying is to be effectively tackled

Bullying and the nursing profession in Australia: an integrative review of the literature

Background: Bullying in nursing remains unacceptable with reports of bullying and harassment increasing. Aim: This article discusses the current state of knowledge about bullying in the nursing profession in Australia. Methods: The review was informed by the approach described by Whittemore and Knafl. A literature search was conducted using thefollowing search terms: ‘nurse OR nursing OR nurses’ AND ‘bullying OR bully OR violence OR harassment’ AND ‘Australia’. Findings: The findings highlight the many ways in which the experience of bullying in the nursing profession can be manifested and the implications for the profession as a whole. Discussion: The culture, prevalence and impact of bullying described in this paper raises concerns for practitioners, educators and policy makers. Conclusion: In order to develop effective strategies for both nurses and organisations to address the problem of bullying in nursing in Australia, the contributing factors that allow the problem to persist must first be examined
