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

Compassion Fatigue Rounds (CFR): A Proactive Brief Intervention to Introduce Mental Health Awareness in a Veterinary Clerkship

The mental health and well-being of veterinary students and graduate veterinarians is a critical area of concern. Veterinary students experience high levels of psychological distress, particularly during transitional periods such as clinical training. While mental health interventions typically target pre-clinical years, the unique challenges faced by clinical students are often overlooked, resulting in inadequate support during important periods of professional development. To address this gap, Compassion Fatigue Rounds (CFR) were introduced. CFR is a proactive, integrated intervention within one clinical clerkship program. The rounds address compassion fatigue, burnout, and self-care practices through a small group discussion facilitated by the clinical instructor. An evaluation of CFR was conducted through anonymous online student surveys administered between March and September 2023. Following CFR, students self-reported an increase in knowledge, confidence, and preparedness regarding the mental health challenges in veterinary medicine. Students overwhelmingly reported positive experiences, pointing to the potential effectiveness of CFR in educating, engaging, and supporting clinical students on mental health well-being. This study offers preliminary evidence for integrating mental health education into the clinical year curriculum and serves as a practical guide for clinical instructors.

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.

Measurement of compassion fatigue in animal health care professionals: a systematic review of available instruments and their content validity

Introduction

Compassion fatigue (CF) refers to emotional or physical exhaustion and emotional reactions resulting from prolonged exposure to traumatic events, commonly experienced by professionals in caregiving roles. CF is prevalent among healthcare professionals, including those in animal care. Several Patient-Reported Outcome Measures (PROMs) were developed to measure CF, but their psychometric validity was not reviewed systematically. This study aims to identify and review the content validity of CF PROMs used in animal health care professionals.

Methods

Literature was searched in PubMed, PsycINFO, and EMBASE (1973-2023). We included studies conducted in animal health care professionals, using a PROM to measure CF, reporting at least one psychometric property of this PROM, and published as original research. For each identified PROM, additional literature search was conducted to identify PROM development and content validation studies. Three independent reviewers evaluated the content validity of each PROM using COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) methodology and summarized the quality of evidence using a modified GRADE approach. The protocol was registered in PROSPERO (CRD42023433982) and results reported following PRISMA guidelines.

Results

Initially, 1709 studies were identified. After a double screening, 17 eligible studies were included. CF was measured using six different PROMs or their modified versions. Only one PROM specifically targeted animal health care professionals: the ProQOL-5 Veterinary Medicine Version. This and three other original CF PROMs were reviewed. For all PROMs, the quality of content validity was rated as insufficient due to deficiencies in the concept and items elicitation, inadequate target population representation, and inadequate details on cognitive interview procedures. The overall evidence quality was rated as low due to a limited number of PROM validation studies, poor methodological and reporting quality, and indirect result.

Discussion

There is a scarcity of studies examining CF within the target population, and the quality of evidence for content validity of the reviewed PROMs for CF measurement is currently low. CF definition and construct description in PROM development studies suffer from vagueness and seem inadequately reflected by the content of the reviewed PROMs. Further research with a robust methodology seems necessary to address the identified flows.

Impact of quality and transparency in scientific writing on the reduction of animal usage in experimental protocols: a review based in pertinent literature

The irreproducibility in scientific research has become a critical issue. Despite the essential role of rigorous methodology in constructing a scientific article, more than half of publications, on average, are considered non-reproducible. The implications of this irreproducibility extend to reliability problems, hindering progress in technological production and resulting in substantial financial losses. In the context of laboratory animal research, this work emphasizes the importance of choosing an appropriate experimental model within the 3R's principle (Refine, Reduce, Replace). This study specifically addresses a deficiency in data specification in scientific articles, revealing inadequacies in the description of crucial details, such as environmental conditions, diet, and experimental procedures. For this purpose, 124 articles from journals with relevant impact factors were analyzed, conducting a survey of data considered important for the reproducibility of studies. Important flaws in the presentation of data were identified in most of the articles evaluated. The results of this study highlight the need to improve the description of essential information, standardizing studies, and ensuring the reproducibility of experiments in areas such as metabolism, immunity, hormones, stress, among others, to enhance the reliability and reproduction of experimental results, aligning with international guidelines such as ARRIVE and PREPARE.

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.

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.

Development of a novel primate welfare assessment tool for research macaques

Primates are important species for biomedical research and ensuring their good welfare is critical for research translatability and ethical responsibility. Systematic animal welfare assessments can support continuous programme improvements and build institutional awareness of areas requiring more attention. A multi-facility, collaborative project aimed to develop and implement a novel primate welfare assessment tool (PWAT) for use with research macaques. PWAT development involved: establishing an internal focus group of primate subject matter experts, identifying animal welfare categories and descriptors based on literature review, developing a preliminary tool, beta-testing the tool to ensure practicality and final consensus on descriptors, finalising the tool in a database with semi-automated data analysis, and delivering the tool to 13 sites across four countries. The tool uses input- and outcome-based measures from six categories: physical, behavioural, training, environmental, procedural, and culture of care. The final tool has 133 descriptors weighted based upon welfare impact, and is split into three forms for ease of use (room level, site level, and personnel interviews). The PWAT was trialled across facilities in March and September 2022 for benchmarking current macaque behavioural management programmes. The tool successfully distinguished strengths and challenges at the facility level and across sites. Following this benchmarking, the tool is being applied semi-annually to assess and monitor progress in behavioural management programmes. The development process of the PWAT demonstrates that evidence-based assessment tools can be developed through collaboration and consensus building, which are important for uptake and applicability, and ultimately for promoting global improvements in research macaque welfare.

Exploring Compassion towards Laboratory Animals in UK- and China-Based Undergraduate Biomedical Sciences Students

Taking a compassionate approach to the non-human animals used in biomedical research is in line with emerging ideas around a "culture of care". It is important to expose biomedical sciences students to the concept of a culture of care at an early stage and give them opportunities to explore related practices and ideas. However, there is no simple tool to explore biomedical sciences students' attitudes towards laboratory animals. Accordingly, there is little understanding of students' feelings towards these animals, or a means of quantifying potential changes to these feelings. We developed a 12-item questionnaire designed to explore compassion (the Laboratory Animal Compassion Scale; LACS) and used it with UK-based and China-based samples of undergraduate biomedical sciences students. In the same samples, we also explored a harm-benefit analysis task and students' beliefs regarding some mental characteristics of laboratory animals, then drew correlations with the quantitative measure of compassion. Compassion levels were stable across years of study and were not related to students' level of experience of working with laboratory animals. We observed a higher level of compassion in females versus males overall, and a higher level overall in the UK-based versus China-based sample. In a task pitting animal suffering against human wellbeing, students' compassion levels correlated negatively with their acceptance of animal suffering. Compassion levels correlated positively with a belief in animals being conscious and possessing emotions. These data are in line with studies that show compassion is gender- and nationality/culture-dependent, and points to links between compassion, beliefs, and choices.
