Stresses on healthcare systems and moral distress among clinicians are urgent, intertwined bioethical problems in contemporary healthcare. Yet conceptualizations of moral distress in bioethical inquiry often overlook a range of routine threats to professional integrity in healthcare work. Using examples from our research on frontline physicians working during the COVID-19 pandemic, this article clarifies conceptual distinctions between moral distress, moral injury, and moral stress and illustrates how these concepts operate together in healthcare work. Drawing from the philosophy of healthcare, we (...) explain how moral stress results from the normal operations of overstressed systems; unlike moral distress and moral injury, it may not involve a sense of powerlessness concerning patient care. The analysis of moral stress directs attention beyond the individual, to stress-generating systemic factors. We conclude by reflecting on how and why this conceptual clarity matters for improving clinicians’ professional wellbeing, and offer preliminary pathways for intervention. (shrink)

Background Italy was the first European country to be involved with the COVID-19 pandemic. As a result, many healthcare professionals were deployed and suddenly faced end-of-life care management and its challenges. Aims To understand the experiences of palliative care professionals deployed in supporting emergency and critical care staff during the COVID-19 first and second pandemic waves. Research design A qualitative descriptive design was adopted, and in-depth interviews were used to investigate and analyse participants’ perceptions and points of view. Participants and (...) research context Twenty-four healthcare professionals (physicians, nurses, psychologists, physiotherapists, and spiritual support) from the most affected areas of Italy were recruited via the Italian society of palliative care and researchers’ network. Ethical considerations The University Institutional Board granted ethical approval. Participants gave written informed consent and agreed to be video-recorded. Findings The overarching theme highlighted participants’ experience supporting health professionals to negotiate ethical complexity in end-of-life care. Crucial topics that emerged within themes were: training emergency department professionals on ethical dimensions of palliative and end-of-life care, preserving dying patients’ dignity and developing ethical competence in managing end-of-life care. Conclusions Our study showed palliative care teams’ challenges in supporting health professionals’ ethical awareness in emergencies. However, while they highlighted their concerns in dealing with the emergency staff’s lack of ethical perspectives, they also reported the positive impact of an ethically-informed palliative care approach. Lastly, this study illuminates how palliative care professionals’ clinical and ethical competence might have assisted a cultural change in caring for dying patients during COVID-19 and future emergencies.

Background: Troubled conscience among nurses and other healthcare workers represents a significant contributor to healthcare worker moral distress, burnout and attrition. While research in this area has examined critical care in hospitals, less knowledge has been obtained from long-term care contexts such as nursing homes, despite widely recognised challenges with regard to vulnerable patients, increasing workload and maintaining workforce sustainability among nurses. Objective: The aim of this study was to illuminate and interpret the meaning of the lived experience of troubled (...) conscience among registered nurses (RNs) working in nursing homes. Research design: This qualitative research employed narrative interviews with eight nurses to obtain essential meanings of their lived experiences of troubled conscience. The interview texts were analysed using a phenomenological hermeneutic approach. Ethical considerations: Participation was voluntary, informed and was conducted with written consent. The Norwegian Centre for Research Data approved the data processing of personal data. Findings: The analysis uncovered two themes: (1) troubled conscience means abandoning ideals, with the subthemes: failing dependent patients; being disloyal to colleagues; being inadequate in the performance of work tasks and (2) troubled conscience means facing realities, with the subthemes: accepting being part of the system; responding to barriers. Discussion: Troubled conscience meant experiencing continuous and simmering tension between one’s ideals and realities and feeling a drive to preserve accountability and one’s moral integrity. Endangered ideals were often under cross-pressure and included humanistic values, professional values, working life values and the values of the organisation. Conclusion: Nurses’ troubled conscience refers to a struggle, but also a force that plays out at various levels and arenas in long-term care. Openness and dialogue about how professional values and the welfare state’s intentions can be realised within the given framework are important for individual nurses’ occupational health as well as the quality of care provided to patients.

The COVID‐19 pandemic has placed extraordinary stress on frontline healthcare providers as they encounter significant challenges and risks while caring for patients at the bedside. This study used qualitative research methods to explore nurses and respiratory therapists' experiences providing direct care to COVID‐19 patients during the first surge of the pandemic at a large academic medical center in the Northeastern United States. The purpose of this study was to explore their experiences as related to changes in staffing models and to (...) consider needs for additional support. Twenty semi‐structured interviews were conducted with sixteen nurses and four respiratory therapists via Zoom or by telephone. Interviews were transcribed verbatim, identifiers were removed, and data was coded and analyzed thematically. Five major themes characterize providers' experiences: a fear of the unknown, concerns about infection, perceived professional unpreparedness, isolation and alienation, and inescapable stress and distress. This manuscript analyzes the relationship between these themes and the concept of moral distress and finds that some, but not all, of the challenges that providers faced during this time align with previous definitions of the concept. This points to the possibility of broadening the conceptual parameters of moral distress to account for providers' experiences of treating patients with novel illnesses while encountering institutional and clinical challenges.

Background: In modern healthcare, the role of solidarity, altruism and the natural response to moral challenges in life-threatening situations is still rather unexplored. The COVID-19 pandemic provided an opportunity to obtain a deeper understanding of nurses’ willingness to care for patients during crisis. Objective: To elucidate clinical expressions of ontological situational ethics through nurses’ willingness to work during a pandemic. Research design, participants and context: A qualitative study with an interpretive design was applied. Twenty nurses who worked in intensive care (...) unit at two Swedish hospitals during the first, second, and third waves of the COVID-19 pandemic were interviewed. The analysis was interpretative and applied a theoretical ethics perspective. Ethical considerations: The study was approved by the Swedish Ethical Review Authority and informed consent was obtained from all participants. Findings: From a philosophical perspective, the nurses expressed sovereign life expressions of mercy and compassion, which arose spontaneously in response to seeing vulnerable fellow humans. They referenced ‘‘the nurse inside me’’ and their choice of profession as motives to provide care. Ontological situational ethics in culture and norms were noted in the constructs of competence, responsibility, solidarity with colleagues and organization; and interest and learning were driving forces. Ethical demand was evident when nurses expressed ideas of meaningfulness in helping their fellow humans; but themes of ambiguity, exhaustion and unwillingness were also present. Conclusions: The nurses showed a high willingness to care for patients during a crisis. Responding to the ethical demand and to care for vulnerable human beings while risking their own health and lives could be interpreted as an inter-human vocation. These spontaneous altruistic actions saved the lives of many patients during the pandemic and need to be understood and supported. (shrink)

In this article, we provide a philosophical and ethical reflection about quiet quitting as a tool of political resistance for nurses. Quiet quitting is a trend that gained traction on TikTok in July 2022 and emerged as a method of resistance among employees facing increasing demands from their workplaces at the detriment of their personal lives. It is characterised by employees refraining from exceeding the basic requirements outlined in their job descriptions. To understand why quiet quitting can be a tool (...) of resistance useful for nurses, we first draw on Frédéric Gros' concept of ‘surplus obedience’ and Michael Lipsky's notion of ‘routines and simplification strategies’ to highlight the ethical implications associated with nurses engaging in and sustaining harmful systems, such as the neoliberal healthcare system. Leaning again on Gros, we then propose that ‘obedience a minima’, a concept akin to quiet quitting, can serve as a method of ethical nursing resistance. After describing what the concept entails, we provide a discussion emphasising the potential of obedience a minima as a one method, among many, that can be leveraged by nurses to challenge and resist a system that prioritises financial considerations over patient wellbeing. The article concludes by reflecting on the ethical nature of resistance in the context of nursing, that is the act of obeying oneself and refraining from participating in systems that are detrimental to the lives of Others.

Background: The high public demand for healthcare services during the COVID-19 pandemic and strict infection control measures, coupled with threat of severe illness and death, and limited resources, led to many healthcare workers (HCWs) experiencing ethically challenging situations (ECSs). Objective: To systematically explore first-hand accounts of ECS-evoking moral distress among HCWs during this public health emergency. Research design: This was an open cohort study. All participants were asked whether they had been in ECS-evoking moral distress during the pandemic. Those who (...) had were asked to describe these situations. Answers were systematically analyzed according to three levels of root causes for ECSs, using thematic analysis. Participants and research context: In January 2022, 977 HCWs from four Norwegian university hospitals participated. Ethical considerations: The study received ethical approval from the Norwegian Ethical Review Authority (No. 130944). Results: In total, 508 participants (52%) reported that they had experienced ECS-evoking moral distress during the pandemic, whereof 323 provided a qualitative description. We found that while a few reported ECSs caused at the patient level, and some described situations at the unit/team level, the vast majority reported situations caused at the system level, predominantly related to resource scarcity, particularly poor staffing. Conclusion: Our findings strongly indicate that efforts to mitigate moral distress among HCWs should be targeted at the system level. More specifically, the study findings highlight resource limitations, particularly poor staffing, as a major cause of moral distress during the pandemic. (shrink)

Background The global pandemic raised ethical issues for nurses about caring for all patients, not just those with COVID-19. Italy was the first European country to be seriously affected by the first wave, while Estonia’s infection and death rates were among the lowest in Europe. Did this raise different ethical issues for nurses in these two countries as well? Aim The aim was to describe and compare ethical issues between nurses working during the first wave of the COVID-19 pandemic in (...) Estonia and Italy. Research design A cross-sectional survey study with a self-administered questionnaire. The impact of COVID- 19 emergency on nursing care questionnaire was used. Participants and research context Convenience sampling was used to recruit 1098 nurses working during the first wave of the pandemic in 2020: 162 from Estonia and 936 from Italy. Ethical considerations Research ethics approvals were obtained, and the nurses provided informed consent. Results The most frequent ethical issues for Estonian nurses were professional communication and ensuring access to care for patients without COVID-19, and for Italian nurses, the end-of-life care and the risk of them getting the virus and transmitting it to their loved ones. There were no statistically significant differences in the frequency of ethical issues between Estonian nurses working with patients with and without COVID-19. Italian nurses caring for COVID-19 patients faced statistically significantly more (both p <.001) issues around prioritising patients and end-of-life. Nurses working with patients without COVID-19 in Italy faced more issues about access to care ( p <.001). Conclusions Estonian and Italian nurses, working in different clinical contexts during the first wave of the pandemic, faced different ethical issues. Local contextual aspects need to be considered to support nurses’ ethical decision-making in providing care during future crises and to ensure ethical care for patients. (shrink)

South African research ethics committees (RECs) faced significant challenges during the COVID-19 pandemic. Research ethics committees needed to find a balance between careful consideration of scientific validity and ethical merit of protocols, and review with the urgency normally associated with public health emergency research. We aimed to explore the views of South African RECs on their pandemic preparedness and response during COVID-19. We conducted in-depth interviews with 21 participants from RECs that were actively involved in the review of COVID-19 related (...) research, at seven academic institutions across South Africa. Interviews were conducted remotely using an in-depth interview guide that included questions regarding REC preparedness and response to COVID-19. Interviews were conducted until data saturation, and audio-recordings were transcribed verbatim and coded. An inductive approach to thematic analysis was used to organise data into themes and sub-themes. This study focused on three main themes: coping during COVID-19, building REC capacity during pandemic times and a consistently cautious approach to mutual recognition of REC reviews. Despite an initial sense of unpreparedness, RECs were able to adapt and maintain careful ethical oversight of both COVID and non-COVID research, and the rigour of REC reviews. Several important lessons for preparedness and response to future pandemics were identified, including heightened awareness of publication, funding and political pressures, the importance of regular training for RECs and researchers, and strategies to enhance moral resilience of REC members. Incremental steps are needed to build trust and authentic partnerships among RECs in inter-pandemic times, to facilitate collaboration during future public health emergencies. (shrink)

Background Moral distress appears when a healthcare professional is not able to carry out actions in accordance with their professional ethical standards. The Moral Distress Scale-Revised is the most widely used to assess levels of moral distress, but it is not validated in Spanish. The aim of the study is to validate the Spanish version of the Moral Distress Scale – utilised within a sample of Spanish healthcare professionals treating COVID–19 patients. Methods The original (english) and the portuguese and french (...) versions of the scale were translated into spanish by native or bilingual researchers and reviewed by an academic expert in ethics and moral philosophy as well as by a clinical expert. Research design: Descriptive cross-sectional study carried out using a self-reporting online survey. The data was collected between June- November 2020. A total of 661 professionals responded to the survey (N = 2873). Participants: healthcare professionals with more than two weeks of experience treating COVID–19 patients at the end of their life and working in the public sector of the Balearic Islands Health Service (Spain). Analyses included descriptive statistics, competitive confirmatory factor analysis, evidence on criterion-related validity and estimates of reliability. The study was approved by the Research Ethics Committee at the University of Balearic Islands. Results An unidimensional model in which a general factor of moral distress explained by 11 items of the Spanish version of the MDS–R scale was an adequate representation of the data: χ 2 (44) = 113.492 (p 0.001); Comparative Fit Index = 0.965; Root Mean Square Error of Approximation = 0.079[0.062,0.097]; and Standarized Root Mean-Square = 0.037. Evidence of reliability was excellent: Cronbach’s alpha = 0.886 and McDonald’s omega = 0.910. Moral distress was related to discipline, with nurses having statistically significant higher levels than physicians. Additionally, moral distress successfully predicted professional quality of life, with higher levels of moral distress being related to poorer quality of life. Conclusions The Spanish version of Moral Distress Scale–Revised can be used as a reliable and valid measurement tool for the evaluation of moral distress experienced by health professionals. This tool will be highly useful for managers and applicable to a variety of healthcare professionals and settings. (shrink)

While various definitions of moral distress have been proposed, some agreement exists that it results from illegitimate constraints in clinical practice affecting healthcare professionals’ moral agency. If we are to reduce moral distress, instruments measuring it should provide relevant information about such illegitimate constraints. Unfortunately, existing instruments fail to do so. We discuss here several shortcomings of major instruments in use: their inability to determine whether reports of moral distress involve an accurate assessment of the requisite clinical and logistical facts (...) in play, whether the distress in question is aptly characterized as moral, and whether the moral distress reported is an appropriate target of elimination. Such failures seriously limit the ability of empirical work on moral distress to foster appropriate change. (shrink)

Background: During the COVID-19 pandemic, frontline workers faced a series of challenges balancing family and work responsibilities. These challenges included making decisions about how to reduce COVID-19 exposure to their families while still carrying out their employment duties and caring for their children. We sought to understand how frontline workers made these decisions and how these decisions impacted their experiences.Methods: Between October 2020 and May 2021, we conducted 61 semi-structured interviews in English or Spanish, with individuals who continued to work (...) outside of the home during the pandemic and had children living at home. Interviews were recorded, transcribed verbatim, and analyzed using abductive methods.Results: Frontline workers experienced moral distress, the inability to act in accordance with their values and obligations because of internal or external constraints. Their moral distress was a result of the tensions they felt as workers and parents, which sometimes led them to feel like they had to compromise on either or both responsibilities. Individuals felt morally conflicted because 1) their COVID-19 work exposures presented risk that often jeopardized their family’s health; 2) their work hours often conflicted with their increased childcare responsibilities; and 3) they felt a duty to their colleagues, patients/customers, and communities to continue to show-up to work.Conclusions: Our findings point to a need to expand the concept of moral distress to include the perspectives of frontline workers outside of the healthcare professions and the fraught decisions that workers make outside of work that may impact their moral distress. Expanding the concept of moral distress also allows for a justice-based framing that can focus attention on the disparities inherent in much frontline work and can justify programmatic recommendations, like increasing paid childcare opportunities, to alleviate moral distress.

BackgroundCommentators believe that the ethical decision-making climate is instrumental in enhancing interprofessional collaboration in intensive care units. Our aim was twofold: to determine the perception of the ethical climate, levels of moral distress, and intention to leave one's job among nurses and physicians, and between the different ICU types and determine the association between the ethical climate, moral distress, and intention to leave.MethodsWe performed a cross-sectional questionnaire study between May 2021 and August 2021 involving 206 nurses and physicians in a (...) large urban academic hospital. We used the validated Ethical Decision-Making Climate Questionnaire and the Measure of Moral Distress for Healthcare Professionals tools and asked respondents their intention to leave their jobs. We also made comparisons between the different ICU types. We used Pearson's correlation coefficient to identify statistically significant associations between the Ethical Climate, Moral Distress, and Intention to Leave.ResultsNurses perceived the ethical climate for decision-making as less favorable than physicians. They also had significantly greater levels of moral distress and higher intention to leave their job rates than physicians. Regarding the ICU types, the Neonatal/pediatric unit had a significantly higher overall ethical climate score than the Medical and Surgical units and also demonstrated lower moral distress scores and lower “intention to leave” scores compared with both the Medical and Surgical units. The ethical climate and moral distress scores were negatively correlated ; moral distress and "intention to leave" was positively correlated ; and ethical climate and “intention to leave” were negatively correlated.ConclusionsSignificant differences exist in the perception of the ethical climate, levels of moral distress, and intention to leave between nurses and physicians and between the different ICU types. Inspecting the individual factors of the ethical climate and moral distress tools can help hospital leadership target organizational factors that improve interprofessional collaboration, lessening moral distress, decreasing turnover, and improved patient care.

During the COVID-19 pandemic, nurses experienced tremendous dilemmas including the need to perform their duties in caring for patients while they have concerns about contracting the disease. This study described the moral distress of nurses in-charge of handling COVID-19 patients which can be used as baseline data for intervention programs in overcoming moral distress among nurses. This descriptive, cross-sectional study was conducted with nurses in-charge of handling COVID-19 treatment rooms. Before conducting the survey, ethical approval was obtained from the Medical (...) Faculty of Universitas Hasanuddin. Questionnaires on moral distress for clinical nurses and the demographic data questionnaire were distributed to 128 respondents. These nurses experienced relatively low levels of moral distress despite the fact that they were generally exposed to morally stressful situations. Education background appeared as a factor influencing this condition, in which higher moral distress was mostly experienced by nurses with undergraduate education. (shrink)

Background Nurses frequently face situations in their daily practice that are ethically difficult to handle and can lead to moral distress. Objective This study aimed to explore the phenomenon of moral distress and describe its work-related predictors and individual consequences for home-care nurses in Germany. Research design A cross-sectional design was employed. The moral distress scale and the COPSOQ III-questionnaire were used within the framework of an online survey conducted among home-care nurses in Germany. Frequency analyses, multiple linear and logistic (...) regressions, and Rasch analyses were performed. Participants and research context The invitation to participate was sent to every German home-care service ( n = 16,608). Ethical considerations The study was approved by the Data Protection Office and Ethics Committee of the German Federal Institute for Occupational Safety and Health. Results A total of 976 home-care nurses participated in this study. Job characteristics, such as high emotional demands, frequent work-life-conflicts, low influence at work, and low social support, were associated with higher disturbance caused by moral distress in home-care nurses. Organizational characteristics of home-care services, such as time margin with patients, predicted moral distress. High disturbance levels due to moral distress predicted higher burnout, worse state of health, and the intention to leave the job and the profession, but did not predict sickness absence. Conclusions To prevent home-care nurses from experiencing severe consequences of moral distress, adequate interventions should be developed. Home-care services ought to consider family friendly shifts, provide social support, such as opportunities for exchange within the team, and facilitate coping with emotional demands. Sufficient time for patient care must be scheduled and short-term takeover of unknown tours should be prevented. There is a need to develop and evaluate additional interventions aimed at reducing moral distress, specifically in the home-care nursing sector. (shrink)

Background Nurses providing care to patients with end-of-life or terminal illnesses often encounter ethically challenging situations leading to moral distress. However, existing quantitative studies have examined moral distress using instruments that address general clinical situations rather than those specific to end-of-life care. Furthermore, qualitative studies have often been limited to participants from a single unit or those experiencing moral distress-induced circumstances. A comprehensive and integrated understanding of the overarching process of moral distress is vital to discern the unique circumstances surrounding (...) end-of-life care and its consequential impacts. Research objectives To explore the moral distress experiences of nurses who are frequently involved in caring for patients with end-of-life or terminal illnesses and apply it to two existing theories: the model of moral distress and the ecological model. Research design A qualitative descriptive approach was employed. Participants and research context Seven focus group interviews involving 30 nurses were performed. The subsequent transcriptions underwent rigorous content analysis. Ethical considerations We obtained Institutional Review Board approval from a university. Focus group interviews were conducted with nurses who agreed to participate and signed the consent form. Findings The moral distress-inducing factors and nurses’ perceived impact of moral distress were identified and categorized based on moral distress theories and ecological models. A total of 15 categories and 30 subcategories across the following 4 domains were derived: (1) intrapersonal, (2) interpersonal, (3) organizational, and (4) structural factors. Conclusions End-of-life-specific circumstances induced moral distress among nurses, with both negative and positive impacts identified. Effective organizational and policy support is essential to manage conflicts, form a healthy organizational culture, provide training, and prevent unnecessary expenses due to the negative consequences of moral distress.

Background Nurses experienced intense ethical and moral challenges during the COVID-19 pandemic. Our 2020 qualitative parent study of frontline nurses’ experiences during the COVID-19 pandemic identified ethics as a cross-cutting theme with six subthemes: moral dilemmas, moral uncertainty, moral distress, moral injury, moral outrage, and moral courage. We re-analyzed ethics-related findings in light of refined definitions of ethics concepts. Research aim To analyze frontline U.S. nurses’ experiences of ethics during the COVID-19 pandemic. Research design Qualitative analysis using a directed content (...) methodology. Participants and research context The study included 43 nurses from three major metropolitan academic medical centers and one community hospital in the northeastern, mid-Atlantic, midwestern, and western United States. Ethical considerations Participant privacy and data confidentiality were addressed. Findings Moral dilemmas arose from many situations, most frequently related to balancing safety and patient care. Moral uncertainty commonly arose from lacking health information or evidence about options. Moral distress occurred when nurses knew the right thing to do, but were prevented from doing so, including with end-of-life issues. Moral injury (accompanied by suffering, shame, or guilt) occurred after doing, seeing, or experiencing wrongdoing, often involving authority figures. Nurses expressed moral outrage at events and people within and outside healthcare. Despite difficult ethical situations, some nurses exemplified moral courage, sometimes by resisting policies they perceived as preventing compassionate care, guided by thinking about what was best for patients. Discussion This content analysis of ethics-related subthemes revealed conceptual characteristics and clarified distinctions with corresponding exemplars. Conceptual clarity may inform responses and interventions to address ethical quandaries in nursing practice. Conclusions Ethics education in nursing must address the moral dilemmas of pandemics, disasters, and other crises. Nurses need time and resources to heal from trying to provide the best care when no ideal option was available. (shrink)

Background Nurses tasked with providing care which they perceive as increasing suffering often experience moral distress. Response to moral distress in nurse wellbeing has been widely studied. Less research exists that probes practicing nurses’ foundations of moral beliefs. Aims The purpose of this phenomenological study was to gain understanding of nurse meaning-making of morally distressing situations, with particular attention to ethical norms, moral agency and resiliency, and nurse religious/spiritual orientation. Design This exploratory study employed semi-structured interviews using open-ended questions. Qualitative (...) data analysis was assisted by MAXQDA software. Participants and research context Nine pulmonary care nurses during COVID-19 in a tertiary care teaching hospital in the northeastern United States. Ethical considerations The study was approved by the IRB. Participants were consented before the study and confidentiality was preserved. Findings/results The study revealed three main themes of meaning-making, rooted in the identity of the “good nurse”: Being true to one’s own values, pursuing ideal patient care (“doing good”), and conforming to/challenging values of the system and culture. Tensions were found between (a) nurse’s own values (b) duty to institutional norms and duty to nurse’s personal code of ethics, and (c) perceptions of institutional support in response to nurse moral distress. Religion was described as a remote source of nurse moral values, among other sources. Spiritual practices were not experienced as sufficient in coping with moral distress at the bedside. Conclusions The study suggests nurses need more opportunities to engage in reflection on their practice and values. The findings also indicate need for accessible institutional supports for nurses experiencing moral distress and strategic use of chaplains in helping with moral distress. Further research is needed on the interplay of nurse spirituality, moral agency, and reflective practice in the face of morally challenging situations. (shrink)

The global pandemic has intensified the risk of moral distress due to increased demands on already limited human resources and uncertainty of the pandemic’s trajectory. Nurses commonly experience moral distress: a conflict between the morally correct action and what they are required or capable of doing. Effective moral distress interventions are rare. For this reason, our team conducted a multi-phase research study to develop a moral distress intervention for pediatric critical care nurses. In this article, we discuss our multi-phase approach (...) to develop a moral distress intervention—proactive, interdisciplinary meeting. Our proposed intervention is a sequential compilation of empirical work couched within a relational ethics lens thus should point to enhanced potential for intervention effectiveness. (shrink)
