Critical Care Nurses' Moral Resilience, Moral Injury, Institutional Betrayal, and Traumatic Stress After COVID-19.

BACKGROUND: Traumatic stress and moral injury may contribute to burnout, but their relationship to institutional betrayal and moral resilience is poorly understood, leaving risk and protective factors understudied. OBJECTIVES: To examine traumatic stress symptoms, moral injury symptoms, moral resilience, and institutional betrayal experienced by critical care nurses and examine how moral injury and traumatic stress symptoms relate to moral resilience, institutional betrayal, and patient-related burnout. METHODS: This cross-sectional study included 121 critical care nurses and used an online survey. Validated instruments were used to measure key variables. Descriptive statistics, regression analyses, and group t tests were used to examine relationships among variables. RESULTS: Of participating nurses, 71.5% reported significant moral injury symptoms and/or traumatic stress. Both moral injury symptoms and traumatic stress were associated with burnout. Regression models showed that institutional betrayal was associated with increased likelihood of traumatic stress and moral injury. Increases in scores on Response to Moral Adversity subscale of moral resilience were associated with a lower likelihood of traumatic stress and moral injury symptoms. CONCLUSIONS: Moral resilience, especially response to difficult circumstances, may be protective in critical care environments, but system factors (eg, institutional betrayal) must also be addressed systemically rather than relying on individual-level interventions to address nurses' needs.

The Long Tail of COVID-19: Implications for the Future of Emergency Nursing.

INTRODUCTION: COVID-19 has led to exacerbated levels of traumatic stress and moral distress experienced by emergency nurses. This study contributes to understanding the perspectives of emergency nurses' perception of psychological trauma during COVID-19 and protective mechanisms used to build resilience. METHOD: The primary method was qualitative analysis of semistructured interviews, with survey data on general resilience, moral resilience, and traumatic stress used to triangulate and understand qualitative findings. Analyses and theme development were guided by social identity theory and informed by the middle range theory of nurses' psychological trauma. RESULTS: A total of 14 emergency nurses were interviewed, 11 from one site and 3 from the other. Almost all nurses described working in an emergency department throughout the pandemic as extraordinarily stressful, morally injurious, and exhausting at multiple levels. Although the source of stressors changed throughout the pandemic, the culmination of continued stress, moral injury, and emotional and physical exhaustion almost always exceeded their ability to adapt to the ever-changing landscape in health care created by the pandemic. Two primary themes were identified: losing identity as a nurse and hopelessness and self-preservation. DISCUSSION: The consequences of the pandemic on nurses are likely to be long lasting. Nurses need to mend and rebuild their identity as a nurse. The solutions are not quick fixes but rather will require fundamental changes in the profession, health care organizations, and the society. These changes will require a strategic vision, sustained commitment, and leadership to accomplish.

The Impact of Traumatic Stress, Resilience, and Threats to Core Values on Nurses During a Pandemic.

OBJECTIVE: The aim of this study was to understand the traumatic stress and resilience of nurses who cared for patients with COVID-19. BACKGROUND: Studies have shown a high proportion of healthcare workers are at risk for developing posttraumatic stress disorder after a pandemic. Resilience factors are believed to play an important role in the well-being of healthcare professionals. METHODS: This was a triangulated mixed methods study; a phenomenological qualitative approach with survey data was used to triangulate the findings, and sensemaking was used as the theoretical framework. RESULTS: Four themes emerged from the study: 1) phases of traumatic stress response to perceived threats; 2) honoring their sacrifice; 3) professional self-identity; and 4) sustaining resilience in a stressful work environment. Quantitative results on traumatic stress, general resilience, and moral resilience supported the themes. CONCLUSIONS: The findings will help leaders understand the potential for postpandemic mental health problems and the role of resilience in maintaining well-being.

Are we crying Wolff? 3D printed replicas of trabecular bone structure demonstrate higher stiffness and strength during off-axis loading.

Roux's principle of bone functional adaptation postulates that bone tissue, and particularly trabecular bone tissue, responds to mechanical stimuli by adjusting (modeling) its architecture accordingly. Hence, it predicts that the new modeled trabecular structure is mechanically improved (stiffer and stronger) in line with the habitual in vivo loading direction. While previous studies found indirect evidence to support this theory, direct support was so far unattainable. This is attributed to the fact that each trabecular bone is unique, and that trabecular bone tissue tends to be damaged during mechanical testing. Consequently, a unique modeled trabecular structure can be mechanically tested only along one direction and a comparison to other directions for that specific structure is impossible. To address this issue, we have 3D printed 10 replicas of a trabecular structure from a sheep talus cropped along the 3 principal axes of the bone and in line with the principal direction of loading (denoted on-axis model). Next, we have rotated the same cropped trabecular structure in increments of 10° up to 90° to the bone principal direction of loading (denoted off-axis models) and printed 10 replicas of each off-axis model. Finally, all on-axis and off-axis 3D printed replicas were loaded in compression until failure and trabecular structure stiffness and strength were calculated. Contrary to our prediction, and conflicting with Roux's principle of bone functional adaptation, we found that a trabecular structure loaded off-axis tended to have higher stiffness and strength values when compared to the same trabecular structure loaded on-axis. These unexpected results may not disprove Roux's principle of bone functional adaptation, but they do imply that trabecular bone adaptation may serve additional purposes than simply optimizing bone structure to one principal loading scenario and this suggests that we still don't fully understand bone modeling in its entirety.
