Strengthening Workplace Well-Being in Research Animal Facilities

The culture of care to enhance laboratory animal personnel well-being: a scoping review

There has been intense focus on improving the quality of animal research in recent times. An emerging concept of a 'culture of care' has been proposed as another important pillar to enhance scientific quality, with staff well-being being a critical aspect. Professionals working with research animals can face moral and psychological burdens and are at risk of experiencing work-related stress. However, data on the global prevalence of stress in this population is limited. Equally, it is not clear how these stresses manifest, and what impact they might have on an individual's workplace performance and research quality. The purpose of this review was to identify work-related stress, its prevalence, and map evidence on strategies to mitigate stresses. We also set out to identify studies assessing the association between work-related stress and research quality. A systematic search was conducted across four databases, in addition to hand searching relevant references. We included peer-reviewed publications describing work-related stress, culture of care and laboratory animal professionals. A total of 49 publications were included for data mapping. Compassion fatigue was the most frequently described work-related stress, and its prevalence across Europe and North America is likely to be widespread. Multiple strategies to mitigate compassion fatigue and work-related stress were put forward, however, limited empirical evidence was available to assess success. Moreover, no studies reported empirical data linking work-related stress with research quality, despite several publications stating the case. Further population-specific research and measured assessments are urgently needed to deliver culture of care programmes to improve human well-being, animal welfare and research quality.

The Elephant in the Room: Recognition and Documentation of Personnel Practices That Confound Reproducibility

The ability to apply findings from animal studies efficiently and effectively is predicated on an understanding of biology and pathobiology, how that biology relates to the human systems being modeled, and how the studies are conducted and reported. This overview discusses various factors in research within the animal environment (referred to as extrinsic factors) that the NIH now expects to be documented to foster replicability in science and expand interpretations of study outcomes. Specifically, an important extrinsic factor in research with animals is that of individual personnel who perform handling practices, participate in research interactions, and share an overall presence in the housing facility with animals, all of which can confound reproducibility efforts in biomedical science. An improved understanding of the influences and behaviors of animal research personnel on animal responses is critical with regard to research results and the interpretation of data collected from animal models of biomedical disease.

Professional quality of life in animal research personnel is linked to retention & job satisfaction: A mixed-methods cross-sectional survey on compassion fatigue in the USA

BACKGROUND

Working with research animals can be both rewarding and challenging. The rewarding part of the work is associated with understanding the necessity for animal research to improve the health of humans and animals and the knowledge that one can provide care and compassion for the animals. Challenges with animal research include witnessing stress/pain in animals necessitated by scientific requirements, end of study euthanasia, and societal stigmatization about animal research. These challenges could be compounded with more general workplace stresses, in turn, impacting job retention and satisfaction. However, these factors have yet to be formally evaluated. Therefore, the purpose of this survey was to comprehensively evaluate professional quality of life's correlation with key workplace metrics.

METHODS

Six institutions were recruited to participate in a longitudinal intervention trial on compassion fatigue resiliency. This manuscript reports key baseline metrics from this survey. A cross-sectional mixed methods survey was developed to evaluate professional quality of life, job satisfaction, retention, and factors influencing compassion fatigue resiliency. Quantitative data were analyzed via general linear models and qualitative data were analyzed by theme.

RESULTS

Baseline data was collected from 198 participants. Personnel who reported higher compassion satisfaction also reported higher retention and job satisfaction. Conversely, personnel who reported higher burnout also reported lower job satisfaction. In response to open-ended questions, participants said their compassion fatigue was impacted by institutional culture (70% of participants), animal research (58%), general mental health (41%), and specific compassion fatigue support (24%).

CONCLUSIONS

In conclusion, these results show that professional quality of life is related to important operational metrics of job satisfaction and retention. Furthermore, compassion fatigue is impacted by factors beyond working with research animals, including institutional culture and general mental health support. Overall, this project provides rationale and insight for institutional support of compassion fatigue resiliency.

Perceived professional quality of life and mental well-being among animal facility personnel in Spain

Animal facility personnel provide the husbandry and care of laboratory animals. We aimed to investigate their work-related quality of life, empathy and mental well-being. Participants living in Spain were contacted by email and asked to complete an anonymous online questionnaire, in which they answered the Professional Quality of Life scale, the Cognitive and affective empathy test, the Warwick-Edinburgh Mental Well-Being Scale, and their perceived human-animal interaction. Participants were asked whether they were receiving psychological therapy or were taking anxiolytics, hypnotics or antidepressant medication. The study comprised 80 participants. No differences were observed related to personal or professional variables. Participants working with small carnivores reported higher total empathy, and those working with non-human primates reported higher emotional comprehension. Higher human-animal interaction was reported by participants working with small carnivores, farm animals and non-human primates. More than half of the participants reported high levels of mental well-being, positively correlated with emotional comprehension, emphatic joy and compassion satisfaction. Participants working with farm animals reported higher levels of secondary traumatic stress that was positively correlated with human-animal interaction and negatively with mental well-being. Most participants reported low-average levels of burnout, which was negatively correlated with mental well-being. The percentage of animal facility personnel in psychotherapy was higher than in the general population, and the consumption of anxiolytics was a little lower and antidepressants higher. Overall, our results indicate that animal-facility personnel who felt stress or worse mental well-being were in therapy and took medication to improve their condition.

Beyond compliance: harmonising research and husbandry practices to improve experimental reproducibility using fish models

Reproducibility in animal research is impacted by the environment, by husbandry practices in the laboratory and by the animals' provenance. These factors, however, are often not adequately considered by researchers. A disconnect between researchers and animal care staff can result in inappropriate housing and husbandry decisions for scientific studies with those animals. This is especially the case for the research in neuro-behaviour, epigenetics, and the impact of climate change, as heritable phenotypic, behavioural or physiological changes are known to result from the animals' environmental housing, husbandry, provenance and prior experience. This can lead to greater variation (even major differences) in data outcomes among studies, driving scientific uncertainties. Herein, we illustrate some of the endpoints measured in fish studies known to be intrinsically linked to the environment and husbandry conditions and assess the significance of housing and husbandry practice decisions for research adopting these endpoints for different fish species. We highlight the different priorities and challenges faced by researchers and animal care staff and how harmonising their activities and building greater understanding of how husbandry practices affect the fish will improve reproducibility in research outcomes. We furthermore illustrate how improving engagement between stakeholders, including regulatory bodies, can better underpin fish husbandry decisions and where researchers could help to drive best husbandry practices through their own research with fish models.

Attending veterinarians improve the research capability and psychological well-being of researchers in animal research institutes

The use of laboratory animals in biomedical research has significantly advanced scientific understanding, yet it raises ethical concerns about animal welfare and the mental health of researchers Recent research has highlighted the potential for stress and compassion fatigue among researchers working with distressed animals. Attending veterinarians (AVs) are crucial in mitigating the pain and stress experienced by animals and, by extension, researchers. However, the impact of AVs on researchers' psychological well-being remains understudied. This study explores how AVs contribute to researchers' research capability and psychological well-being in animal research institutions. AVs oversee animal housing, health, and welfare; their involvement is mandated or strongly recommended in developed countries. AVs enhance animal welfare by ensuring proper housing, nutrition, and social interaction. They monitor animal health, educate researchers on pain assessment, and promote compliance with post-surgical care. AVs also contribute to researchers' well-being by addressing euthanasia procedures, which can be emotionally challenging. Programs for rehoming animals after experiments offer an alternative to euthanasia and positively impact researchers' psychological well-being. Moreover, AVs promote workplace well-being by fostering positive workplace cultures, offering peer counseling, and providing social support. Programs considering animal welfare and researchers' emotions are crucial for a healthy research environment. In conclusion, AVs are essential in balancing scientific progress with animal welfare and researchers' psychological well-being. Therefore, their role should be recognized as vital in achieving social equity that considers the welfare of humans and laboratory animals.

Ethical Aspects of Human Induced Pluripotent Stem Cells and Alzheimer's Disease: Potentials and Challenges of a Seemingly Harmless Method

Dementia currently affects more than 55 million people worldwide, and scientists predict that this number will continue to rise. The most common form is Alzheimer's disease (AD), which is triggered, among other things, by dysfunctional cells in the human brain. Stem cell research attempts to counteract neurodegenerative processes, for example by replacing or treating diseased cells. In addition to human embryonic stem cells, since the successes of Takahashi and Yamanaka in 2006, there has been an increased focus on human induced pluripotent stem cells (hiPS cells). These cells avoid ethically challenging questions about the moral status of human embryos, but there are numerous problems, such as high production costs, side effects from the reprogramming process, or a potentially new moral status. These ethical issues will be examined primarily in relation to AD. The first part will be a discussion of hiPS cells and their importance for stem cell research, after which the focus turns to AD. Based on scientific studies, the relationship between hiPS cells and AD will be outlined as well as ethical implications presented. While potential limitations of hiPS cells have been discussed by numerous authors, an ethical perspective on the link between hiPS cells and AD seems to be neglected in the scientific community. The following risk analysis aims to identify a possible research agenda. In conclusion, the focus on individuals with AD may help to adopt an ethical stance that recognizes existing limitations and constructively engages with the possibilities of research.

Psychological stress and strain in laboratory animal professionals - a systematic review

Laboratory animal professionals (LAP) are faced with various situations and tasks influencing their mental well-being. A systematic review has been conducted to investigate whether there are specific stressors for LAP and which moderators are relevant for the development of psychological strain. A comprehensive search following PRISMA Guidelines was carried out in June 2021. Results include 12 studies and have been summarized qualitatively in narrative synthesis and tabular presentation. Available literature indicates that LAP are facing stressors but does not allow for conclusions on specific stressful job duties other than euthanasia.Signs of strain are present in LAP. Specifically, participants in qualitative studies reported acute symptoms, while chronic manifestations were in focus in quantitative studies. Although a wide variety of moderating factors have been investigated, only social support has been rated as relevant by multiple qualitative and quantitative studies without contrasting results.According to current data, there is a risk for psychological strain in LAP. However, there is limited understanding of specific stressors and data on moderators is diverse. Further studies that focus on domain-specific knowledge and clearly distinguish stressors from moderators are necessary to set up institutional programmes addressing psychological strain in LAP.

Research Animal Behavioral Management Programs for the 21st Century

Behavioral management programs have been developed commonly for research dogs and primates but rarely has program consideration been expanded to include all research species worked with. This is necessary to reduce animal stress and promote natural behaviors, which can promote good animal welfare and result in more robust and reproducible scientific data. We describe the evolution of consideration for research animal needs and define an umbrella-based model of research animal behavioral management programs, which may be used for all research species. In addition to developing a more comprehensive program, we emphasize the need for regular welfare assessments to determine whether the program is working cohesively and whether any aspects require modification.

A Preliminary Assessment of Compassion Fatigue in Chimpanzee Caregivers

Compassion fatigue is defined as "traumatization of helpers through their efforts at helping others". It has negative effects on clinicians including reduced satisfaction with work, fatigue, irritability, dread of going to work, and lack of joy in life. It is correlated with patients' decreased satisfaction with care. Compassion fatigue occurs in a variety of helping professions including educators, social workers, mental health clinicians, and it also appears in nonhuman animal care workers. This study surveyed caregivers of chimpanzees using the ProQOL-V to assess the prevalence of compassion fatigue among this group. Compassion satisfaction is higher than many other types of animal care workers. Conversely, this group shows moderate levels of burnout and secondary traumatic stress; higher levels than other types of animal care workers and many medical professions. While compassion fatigue has an effect on the caregiver's experience, it has potential to affect animal welfare. Caregivers are an integral part of the chimpanzee social network. Compassion fatigue affects the caregiver's attitude, this could in turn affect the relationship and degrade the experience of care for captive chimpanzees. Compassion fatigue can be mitigated with professional development, mindfulness training, interrelationships among staff, and specialized training. This preliminary assessment indicates the work ahead is educating caregivers about compassion fatigue and implementing procedures in sanctuaries to mitigate burnout and secondary traumatic stress.

Compassion Fatigue and Coping Mechanisms of Laboratory Animal Professionals from Europe, China, and Japan

Laboratory animal professionals (LAP) may experience situations that contribute to compassion fatigue (CF). The goal of this research was to better understand CF in LAP in and across employment categories. Surveys were distributed through LAP organizational listservs in the European Union (EU), China, and Japan, and results were analyzed to identify CF prevalence, personal and work-related factors, coping mechanisms, and beneficial work-support programs. Independent χ²-tests compared personal and work-related factors and feelings of CF. Feelings of CF and coping mechanisms were compared with personality scores using independent sample t tests. There were 302 respondents from the EU, 39 from China, and 77 from Japan. Over half of respondents from the EU (52%) and China (56%) reported experiencing CF (52%), with fewer (32%) reporting CF in Japan. No major differences were found based on employer type. Personality scores were significantly related to feelings of CF and preferred coping mechanisms. Work-related factors that contributed to feelings of CF in over half of respondents included staffing levels, workplace relationships, and availability of programs geared to address CF. Across regions, talking to someone, physical activity, getting away from work, and self-care were effective coping mechanisms in over 50% of respondents. Fewer than 30% of respondents indicated that their place of employment had CF support programs, and even fewer (8% to 28%) indicated that these programs were helpful. The study results suggest that to be effective, employer CF programs for LAP should consider providing quiet places at work and programs for self-care, promoting physical and mental health and social support systems, and establishing opportunities to memorialize animals.

Researchers, animal support and regulatory staff: symbiosis or antagonism?

Animals are studied en masse by biologists around the world in a variety of biomedical and basic research studies. All this research benefits humankind and animals alike as it tackles a wide variety of problems ranging from those of conservation biology to medicine. Research with animal subjects is a complex endeavor that requires the cooperation and collaboration of a large number of experts, from the principal investigator through technicians and vivarium staff to regulatory experts. The research must be conducted in a humane manner that adheres to acceptable practices regulated by local, state and federal guidelines, rules and the law. In this short opinion article, we examine the current state of affairs regarding how researchers, animal support staff and regulatory experts work together. We pay particular attention to potential conflicts that may arise from the occasionally distinct roles played by those involved in animal research, and we provide some suggestions as short- and long-term remedies that have not been previously discussed in the literature.

Culture of care in animal research - Expanding the 3Rs to include people

Research on animals is essential for science and medical progress. While it is still necessary to conduct this research, it is essential to apply the highest standards in animal welfare, including animal husbandry and care. Furthermore, it is important to recognize the special relationship between research animals and the people who care for them. Caring for research animals can be extremely fulfilling and meaningful, but it also comes with challenges, particularly when caring for animals experiencing pain or distress. These challenges can lead to work-related mental stress. To get more insight into the challenges of working in animal research, we organized a panel discussion at the GV-SOLAS (German Society for Laboratory Animal Science) and IGTP (Interest Group Animal Caretakers) conference 2021 about work wellbeing. This discussion was the first of its kind in Germany. The active panel contributions included the view of an ethical philosopher, a scientist, a lecturer for laboratory animal science, an animal facility manager and an animal caretaker. They gave insights from their perspective into key factors that can affect human wellbeing in animal research. Keys ideas included stigmatization of work, tension between research aims and animal wellbeing, and the importance of supportive culture to overcome work-related strains, as well as lack of education and supportive environments to cope with emotional stress in the workplace. Overall, the discussion has shown that we must also promote human wellbeing when promoting culture of care in animal research, because there is strong relationship between culture of care and individual performance.

A survey on the use of mice, pigs, dogs and monkeys as animal models in biomedical research in Spain

Background

The use of animals in biomedical science remains controversial. An individual’s level of concern is generally influenced by their culture, previous or current experience with animals, and the specific animal species in question. In this study we aimed to explore what people in Spain who had never or who no longer worked with laboratory animals thought of the use of mice, pigs, dogs and monkeys for biomedical research purposes. We also aimed to determine whether or not people currently involved in biomedical research with the aforementioned species felt their work was justified.

Results

The study comprised a total of 807 participants (never worked = 285, used to work = 56, currently working = 466), almost two thirds of whom were women. Our results revealed that the phylogenetic scale is an important factor in people’s opinions of the use of certain species in research. The percentage of people who were against the use of dogs or monkeys was higher than that of those who were against the use of mice or pigs. The main reasons given for having stopped working with laboratory animals were change of professional career and change in research project. Participants who were currently working with animals believed that their work was justified, but said they did not talk about it with people outside their immediate social circle.

Conclusions

Our findings suggest that there is a difference in moral status between monkeys and mice, as well as between companion animals (dogs) and farm animals (pigs). Our results support the idea that working with laboratory animals is a sensitive issue in Spain.

Caring for the Animal Caregiver-Occupational Health, Human-Animal Bond and Compassion Fatigue

Laboratory Animal Professionals experience many positive and rewarding interactions when caring for and working with research animals. However, these professionals also may experience conflicting feelings and exhaustion when the work is stressful due to factors such as limited resources, making end of life decisions, dealing with conflicting priorities, and negotiating animal care priorities with colleagues. These stresses may be further complicated by each individual's self-understanding and emotional investment in the human-animal bond. The term used for this type of complex emotional conflict and exhaustion is Compassion Fatigue. Compassion Fatigue in the Laboratory Animal Science setting is a combination of physical, emotional and psychological depletion associated with working with and caring for animals and their well-being in a research environment. The University of Washington has developed a Compassion in Science Program called Dare2Care which emphasizes self-care and helps Laboratory Animal Professionals identify stress factors and work toward a personal solution to relieve stress. The first step in developing a resiliency program is to assess the current culture and needs of the organization. At an institutional level we identified that we needed increased communication concerning study endpoints, as well as identified individuals with whom affected personnel can talk about personal concerns. We also implemented community events to reflect on the positive aspects of this field of work. We improved the physical work environment, and provided outlets established for personnel to express feelings via written word or artistically. Lastly, we started working with our Center for One Health to encompass a holisitic approach to the occupational health of our animal caregivers. One health is the relationship and interplay between people, animals and the environment and we needed to include emotional well-being in our assessment of the health of our personnel. A question was added to our occupational health screening form to include additional health or workplace concerns (e.g., Compassion Fatigue) not covered by the questionnaire, and we added a component of Compassion Fatigue awareness in our training program. Here we review the importance of identifying Compassion Fatigue in the animal research setting, focus on developing a compassion resiliency culture and provide tools and coping strategies to validate and strengthen the human-animal bond with research animals and to sustain the care that is necessary for both people and research animals.

Professional Quality of Life in Research Involving Laboratory Animals

Many workers contribute to the success of animal welfare and study outcomes in biomedical research. However, the professional quality of life (ProQoL) of those who work with laboratory animals has not been explored in Spain. To this end, we adapted the ProQoL scale to the Spanish population working with laboratory animals. Participants were contacted by email and asked to complete an anonymous on-line questionnaire. The study comprised a total of 498 participants, 12.4% welfare officers/veterinarians, 19.5% caretaker/technicians, 13.9% principal investigators, 20.7% investigators, 13.6% research technicians, and 19.9% PhD students. The adapted scale revealed very good reliability and internal validity, providing information about two different subscales, compassion satisfaction and compassion fatigue. Animal-facility personnel showed higher total ProQoL and compassion-satisfaction scores than researchers; PhD students showed the lowest scores. Thus, our results indicate that job category is a contributing factor in perceived professional quality of life. We observed that compassion satisfaction is negatively associated with the perceived animal stress/pain. Participants reporting poorer compassion satisfaction also reported lower social-support scores. Overall, our ProQoL scale is a useful tool for analyzing the professional quality of life in the Spanish population, and may help to design future interventions to improve workplace wellbeing in Spain and other Spanish-speaking populations.
