Stress and strain among veterinarians: a scoping review
Irish Veterinary Journal volume 75, Article number: 15 (2022)
The aim of this review is to systematically review studies on work-related stress that may affect the mental health of veterinarians. Studies have indicated a high prevalence of various risk factors for mental disorders among practicing veterinarians. In addition to a high risk of suicide, there is increasing evidence of burnout and depression. A scoping review was conducted using the PubMed, MEDLINE, Scopus, Cochrane Library, Web of Science, PubPsych and PSYNDEX databases. Twenty-one studies (plus seven studies with nonstandardized questionnaires) published between 2000 and 2021 were found that presented data on the effect of workload on the mental wellbeing of veterinarians. All of the included studies indicate a high prevalence of psychological stressors in veterinary practice. The risks of burnout, anxiety and depressive disorders are higher in this occupational group than in the general population and other occupational groups. Subjectively, female veterinarians perceive their psychological workload to be higher than that of their male counterparts. Working hours and ethical dilemmas stand out as major sources of stress. There is a need to improve overall psychological wellbeing of veterinarians. Organizational support services and developing personal strategies for coping with work-related stress can prove helpful.
The identification of work-related stressors and their effects on health has been gaining in importance for many years among employers and researchers. In a meta-analysis  of workplace stressors and the relationship between mortality and health care costs in the United States, which included a total of 228 studies, the major workplace stressors identified were feelings of job inequity, pressure to perform, shift work, feeling of loss of control, low social support in the workplace, and overtime. The study describes that long working hours increase mortality by almost 20%. Moreover, the association between workplace stressors and health is strong in many instances. For example, work–family conflict increases the odds of self-reported poor physical health by about 90% . All stressors mentioned have an impact on the psychological level and are associated with depression, anxiety disorders, and dementia [2, 3]. These stressors also occur among health care workers. In this occupational group, the workloads and their effects on employees appear particularly serious. A large number of studies have shown correlations between job satisfaction and quality of life, physical health, and mental health, especially among health care workers [4, 5]. Primarily, doctors of human medicine in emergency and rescue services and surgery reported high level of subjective stress  as well as increased stress-related physiological strain factors [6,7,8].
Veterinarians are also exposed to similar working conditions and comparable demands. In addition to obvious high physical workloads, which are particularly prevalent in large animal/farm practice [9, 10], psychological stress factors have been examined among veterinarians. Sources of stress identified as psychological stressors in the veterinary profession include work schedules, financial issues, client demands/expectations , and ethical dilemmas regarding treatment options . In 2010, Platt and colleagues found in a systematic review that 14 of the 15 studies reported a higher risk of suicide of veterinarians than in comparison groups . Findings indicating a high risk of suicide among veterinarians have also been reported in Germany .
Burnout and general occupational stress among practicing veterinarians have been important topics in the veterinary community for many years. Stress in the veterinary profession was reported in Germany as early as 1963 , and there have been increasing contributions to this topic in the 1980s and 1990s [15,16,17]. Since the early 2000s, there has been an increase in the number of international research studies on the professional situation among veterinarians [18,19,20,21]. This demonstrates the increasing amount of interest within the research community as well as the need to summarize the findings of these studies to provide information about risk factors (anxiety, ethical conflicts, exhaustion) for occupational mental disorders with an above average duration of illness.
The aim of this scoping review is to provide an overview of the existing evidence on work stress and its effects on the mental health among veterinarians to complement the existing systematic reviews on suicidality [11, 22, 23] or mental disorders in this professional group [11, 24]. Mental disorder is described as a psychological pattern characterised by suffering of the affected person, impairment in one or more important areas of functioning, increased risk of death, or significant loss of autonomy . Whilst the studies included have used various methodologies, our scoping review aims to summarise the prevalence of existing risk factors for threat to mental health in veterinarians.The manuscript is primarily aimed at practicing veterinarians but also includes topics on the general working situation in veterinary medicine. Therefore, veterinary students and employees in veterinary practices can also benefit from the studies and study results described here. The complex topic of mental health should also enable external stakeholders (e.g., social support, occupational scientists, occupational physicians) to gain insights into the profession of veterinary medicine to experience sensitization in dealing with stress and strain among veterinarians.
This scoping review aims to provide an overview of studies related to psychological workload and potential health effects (depression, burnout) in veterinarians. The scoping review was conducted according to a predefined protocol and followed the Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR) guidelines . The protocol was registered in the Open Science Framework .
The PubMed, PubPsych, Scopus, Ovid, Cochrane Library, Web of Science, PSYNDEX, and PsycINFO electronic databases were searched for literature up to July 25, 2021, and the reference lists of included studies were also manually searched to identify additional eligible studies.
The search terms were as follows: »Veterinary emergency service« OR »veterinary physician« OR »veterinary professionals« OR »veterinary surgeon« OR »veterinary physician« OR »Veterinary engineer« OR »veterinary practice« AND »load« OR »stress« OR »strain« OR »work« OR »job« OR »occupational« OR »work load« OR »work stress« OR »mental stress« OR »stress perception« OR »physiological stress« OR »wellbeing» OR »psychological stress« OR »burnout« OR »psyche« OR »mental health« OR »mental work load« OR »dissatisfaction« OR »strain indicator« OR »mental disorder« OR »mental problems« OR »mental illness» OR »anxiety« OR »addictive behaviour« OR »alcohol addiction« OR »suicide«.
To ensure our search was as diverse as possible, search terms such as “addictive behavior” and “alcohol addiction” were also used. Addictive substances are often associated with psychological stress and can provide clues to existing mental illnesses or mental disorders [28, 29]. The inclusion criteria were as follows: practicing veterinarians (regardless of experience level or specialty), original papers, full texts in English or German, and studies with surveys conducted no earlier than 01/01/2000.
Citations not available in open access or that could not be obtained via remote access from the university library or via the authors were excluded. A total of 3,572 articles were retrieved from the literature search (Fig. 1). A total of 4 additional articles was added from the manual search leading to a total of N = 3,576. The identified articles were transferred and documented in Citavi 6 Reference Manager (Swiss Academic Software, Wädenswil, Switzerland). Duplicates were manually removed in advance. Two reviewers (R.P. and B.T.) independently screened the titles and abstracts on the basis of the established inclusion and exclusion criteria. In doing so, the articles reviewed were categorized as “suitable”, “other on topic”, and “not suitable”. If there were discrepancies in the categorization of potentially suitable articles, a third reviewer (I.B.) was consulted.
A total of 46 references met the inclusion criteria and were subjected to full-text screening. This screening was performed by the same reviewers. If studies were excluded during the full-text screening, they were discussed by the review team until a consensus decision was reached. Twenty-eight publications remained after the full-text screening, and the overall study quality of these articles was then assessed. Of these 28 studies, 7 additional studies without valid survey instruments were removed, resulting in a total study count of 21, including 7 publications that were requested through the university library or through the authors, as appropriate Fig 1.
Quality assessment (EPHPP)
The validated Effective Public Health Practice Project (EPHPP) tool  was used to assess the quality of the studies. The EPHPP tool is based on six categories (selection bias, study design, confounders, blinding, data collection, withdrawals and dropouts). Each of these items was rated as strong (1), moderate (2), or weak (3) depending on how well the criteria were met. Studies that had two or more “weak” categories were rated weak (3) overall.
The present review included only studies with valid survey instruments (N = 21). Nevertheless, studies (N = 7) were found to thematically fit our scoping review but collected data exclusively with self-designed questionnaires [12, 31,32,33,34,35]; thus, these studies were excluded. All of the included studies collected data on sociodemographic factors. Eighteen studies were also differentiated by practice type (small animal, large animal, and mixed practice). The results presented herein consist of 20 cross-sectional studies and one longitudinal cohort study. Table 1 shows the studies with standardized questionnaires found in the full-text search, some of which used supplementary questions (e.g., [36,37,38]). In addition to the concise results, Table 1 includes details of the study design and sample, as well as the authors and year of publication. In the following text, a part of the important published results with the questionnaires used is described.
Methodologically, a total of 28 [54,55,56,57,58,59,60,61,62,63,64,65,66,67,68,69,70,71,72,73,74,75,76,77,78,79,80,81] different valid collection instruments with reference to workload, psychosocial stressors, mental wellbeing, burnout, psychological problems, anxiety, depression, and suicidal factors were used (Table 2). All survey instruments, of the studies listed in this section, are presented including description and abbreviation in Table 2.
The prevalence of anxiety and depression among United Kingdom (UK) veterinarians (N = 1,796) reported by Bartram et al.  was 26.3% and 5.8%, respectively, with a HADS subscale score of ≥ 11 (probable case). Best et al.  also used the HADS score to determine the mental health of Canadian veterinarians (N = 412) on anxiety and depression; they found that 32% of participants could be classified as likely anxious based on a HADS-A score ≥ 11, and 9% of participants were classified as likely depressed based on a HADS-D score of ≥ 11. The mean value of the HADS-A was slightly higher at 8.8 points compared to 4.6 points in the Bartram et al.  sample. The same is true for the mean value of the HADS-D score, which was 5.2 points in the study sample of Best et al. compared to 4.6 points in Bartram and colleagues.
Based on the MBI, Human Services Survey decision criteria (a “high” score on emotional exhaustion plus either a “high” score on depersonalization or a “low” score on personal realization), 36.9% of participants could be classified as affected by burnout in Best et al.  (female participants at 37.8% tended to be higher than male participants at 32.7%). The prevalence of work-related burnout (using the MBI) among Finnish veterinarians  found that 40% had moderate sympto ms and 1.7% had severe symptoms. The veterinarians in private practice were the least affected by burnout (2.4% severe and 30.5% moderate), as were community veterinarians (1.3% severe and 37% moderate). Ten percent of veterinarians suffered from work-related fatigue or emotional exhaustion, and 42% suffer from moderate emotional exhaustion. The prevalence of work-related burnout wasmost common among veterinarians working with small animals, equine veterinarians, clinical veterinarians, and veterinarians in private practice. Seven percent of respondents reported severe symptoms of cynicism, and 26% reported moderate cynicism. In self-reported work-related risks, 8% of women and 7% of men reported mental disorders. When asked about their current stress level, 73% of veterinarians (71% of women and 77% of men) reported being rather or more stressed.
In self-reported health information in a study of occupational stress and risk factors among Turkish veterinarians (N = 223) by Cevizci et al. , 19.7% reported suffering from stress, 15.4% reported shortness of breath, 12.8% reported depression, 12% reported burnout, 10.3% reported unhappiness/restlessness, 7.7% reported chronic fatigue/insomnia, and 0.9% reported attention deficit. In addition to nonstandardized data collection instruments, Cevizci et al. examined the sample using the Turkish version of the Swedish Demand-Control-Support Questionnaire but compared veterinarians in the public sector and veterinarians in the private sector. The mean scores collected between the two groups were similar, but only decision latitude was statistically significantly higher among veterinarians in the public sector (3.61 vs. 2.94, p = 0.008).
Crane et al.  examined morality-related stressors (e.g., suspicion of patient/animal abuse, clients unable to pay for recommended treatment, or performing euthanasia) with psychological distress and resilience among Australian veterinarians (N = 540). In addition, the role of perfectionism in strengthening the association between exposure to morally significant stressors and psychological distress was examined. Crane et al. found that moral significance of stressors was statistically significantly related to psychological resilience. Higher levels of perfectionism were statistically significant associated with a tendency to view stressors as more morally statistically significant. They also examined the role of perfectionism in strengthening the association between exposure to morally statistically significant stressors and psychological distress. Perfectionism was positively related to stress (r = 0.509, p < 0.01), anxiety (r = 0.473, p < 0.01), and negative affect (r = 0.444, p < 0.01), and negatively related to resilience (r = − 0.474, p < 0.01).
The relationship between demographic, occupational, and lifestyle factors and resilience, as well as the relationship between resilience and mental health, was examined by Perret et al.  in Canadian veterinarians (N = 1.130). Here, subscale scores (PSS, HADS, MBI, and ProQOL) were each treated as outcomes in univariable linear regression analyses, using the CD-RISC score as the independent variable. Veterinarians’ assessed general health, satisfaction with support from friends, and satisfaction with support from relationships or partners had strong positive associations with resilience. In addition, there is a strong negative association between mental illness and the CD-RISC score. The CD-RISC score was negatively related to scores for perceived stress, anxiety, depression, burnout, and secondary traumatic stress. In addition, there was a statistically significant relationship between the mental health scores of the PSS (mean 17.0, p < 0.001), HADS (mean 13.2, p < 0.001), MBI (emotional exhaustion mean 26.1, p < 0.001, depersonalization mean 8.9, p < 0.001, personal coping mean 36.6, p < 0.001) and CD-RISC (mean 69.9). The mean scores of the ProQOL were 25.2 for burnout, 23.6 for secondary traumatic stress, and 37.8 for compassion satisfaction; however, there were no gender-specific data. Best et al.  also used the ProQOL to assess occupational quality of life there were higher scores for burnout (44.8% vs. 38.9%) and secondary traumatic stress (72.9% vs. 60.7%) in female veterinarians. Although male and female participants had similar scores for compassion satisfaction, men were more likely to score in the “high” category on this subscale (36.3% vs. 31.4%).
Previous studies focused on environmental factors in isolation, overlooking the influence of personality. Dawson et al.  wanted to investigate whether personality is a better predictor of occupational stress than environment. For this they used the NEO Five-Factor Inventory, the MBI, and the Job Stress Survey and found that personality was a better predictor of job stress than environment in British veterinarians (N = 311). Neuroticism is the trait that statistically significant predicts job stress (p < 0.001). Dawson et al. (2017) were found that depression and anger hostility are the components of neuroticism that contribute most to stress. In addition, demographic factors were examined, which are considered as potential mediators and/or moderators of any relationships found. Demographic factors (such as years qualified and type of practice) mediated the relationship between depression and occupational stress (p < 0.001) and moderated the relationship between personal achievement and occupational stress (p = 0.028). Further, the results of Dawson et al. (2017) indicate that newly qualified veterinarians are at greater risk of suffering from high levels of occupational stress than those well established in the profession.
Dow et al.  examined the impact of veterinarians’ (N = 103) psychological wellbeing when dealing with grieving clients using the concept of compassion fatigue (Compassion Fatigue Short Scale (CFSS)). The results of the CFSS show a statistically significant relationship between the total score on the CFSS and hours worked after adjusting for age. Veterinarians who worked 10–20 h per week had a 43-unit lower mean CFSS score than veterinarians who worked 20–30 h per week. Veterinarians aged 18–34 years had a 32-unit higher mean CFSS score than veterinarians aged > 64 years. Regarding the K10 scale, a statistically significant relationship was found between psychological distress and age when adjusting for marital status and animal type (practice type). Younger veterinarians aged 18–34 years had a mean K10 score 8 units higher than older veterinarians aged > 64 years. There was a statistically significant association between psychological distress and marital status when age and animal practice type were considered (p < 0.01). Married and partnered veterinarians had a mean K10 score 3 units lower than veterinarians who were not married or partnered. There was a statistically significant association between psychological distress and animal type when age and marital status were considered (p = 0.031). Veterinarians who dealt with pets, horses, and mixed animals had a mean K10 score 10 units higher than veterinarians who dealt with other animals or were involved in research. Forty percent (40.2%) of respondents reported that their mental/physical health had been affected by euthanasia and 33.69% had experienced difficulty in performing euthanasia because of personal distress. Almost eighty-eight percent (87.6%) of the veterinarians surveyed had experienced grief at the end of an animal’s life.
Hatch et al.  also used the K10 scale, among other measures, in their study to determine the prevalence of depression, anxiety, stress, and burnout and their association with demographic characteristics of Australian veterinarians (N = 1,947). The K10 results were in the low (35.2%), medium (42%), high (14%), and very high (5%) ranges of psychological distress. According to the CBI of veterinarians, 22.2% reported personal burnout, 19.7% reported work-related burnout, and 16.6% reported client-related burnout. Veterinarians from large cities (OR = 2.6, p = 0.03) and from rural cities (OR = 3.1, p = 0.01) were statistically significant more likely to fall into the highest categories of depression scores than veterinarians from rural areas or farms (reference category). Veterinarians’ depression scores (DASS depression score) were distributed as follows: normal (74.5%), mild (7.9%), moderate (10%), severe (3.8%), and extremely severe (3.9%). A total of 83.3% of the veterinarians were classified as anxious (DASS anxiety score). Stress scores among veterinarians were as follows: 68.2% normal and 11.5% mild.
Fritschi et al.  used the GHQ, Warr’s work-related affect scales, and self-report questions to identify levels of stress, anxiety, and depression in veterinarians (N = 2,125). Chi-squared tests were used to determine statistical significance of any differences. The results of the GHQ indicated statistically significant higher psychological distress in women than in men (37.6% vs. 29.7%). Within the gender distributions, the mean value for anxiety (3.72 women vs. 4.04 men) and depression (4.31 vs. 4.46) were proportionally similar. The results from the linear regression analysis of the Warr scales were statistically significant worse for the psychological control variables and the other variables (social support, positive and negative affect) on the anxiety/satisfaction scale for women. Anxiety and depression tended to increase with longer working hours (p < 0.001).
As the only study without gender differentiation, Shirangi et al.  used established psychological scales to measure levels of distress and work-related stress (anxiety and depression) and the demographic and work characteristics of female veterinarians in relation to anxiety, depression and mental health. Thirty-seven percent of female veterinarians scored > 2 on the GHQ, indicating that they suffered from mild mental distress. Sixty-three percent of the female veterinarians scored above the cutoff value of 4 on the CGHQ. The mean score on the anxiety-satisfaction axis was 3.72, and for the depression-enthusiasm axis, it was 4.31 (± 0.82). The means for the positive and negative scales were 33.5 for PA and 18.7 for NA, respectively. The GHQ scores, which assessed psychological distress, indicated that the number of hours worked was related to the work stress felt by the female veterinarians. Women with 2 or 3 children had less anxiety and depression than those without children.
In their study, Hansez et al.  analyzed job engagement, job strain, burnout, work-home interference (WHI), and workplace stressors among veterinarians (N = 216). The mean score of the wellbeing variables studied was 54.06 points for job engagement, 52. Nineteen points indicated work stress, and 22.22 points indicated burnout. The average weekly working time of the respondents was 54.27 h. Men worked more hours than women (58.21 vs. 42.53 h/week). The mean professional commitment (surveyed by the PNOSI) of veterinarians was 54.06 points, with bovine veterinarians showing lower professional commitment than small animal veterinarians. Small animal veterinarians showed lower occupational stress than mixed veterinarians. The WHI is influenced by his subscales, the negative or positive load reactions. The results for work-life interference revealed statistically significant differences in the WHI subscales (p < 0.001).
The results of Harling et al.  showed that German veterinarians (N = 1.131) reported dealing with difficult clients, time pressure, frequent overtime, on-call duty, and weekend service as major reasons for stress. With sum scores in the upper half of the psychosocial stress scale, 19.1% of veterinarians were considered stressed. The more hours worked per week, the more stressed veterinarians were. Self-employed veterinarians experience stress more frequently than veterinarians who are employees. The values in the upper half of the demoralization scale reached 12.2%. Employed veterinarians are more demoralized than self-employed veterinarians, and young veterinarians (without exact definition to “young veterinarians”) are more demoralized than older veterinarians. In addition, severe psychosocial stress (based on a self-constructed scale following the model of occupational gratification crises by Siegrist) is often associated with demoralization.
Kassem et al.  examined the connection between demographic, occupational, and psychological characteristics and negative attitudes toward mental disorder among veterinarians (N = 9,522). The likelihood of having negative attitudes toward treatment efficacy was statistically significant (p < 0.05) higher for men than for women (OR = 1.79); for veterinarians practicing alone than for veterinarians not practicing alone (OR = 1.60); for those with (compared with those without) evidence of severe psychological distress (OR = 2.11); and for those who reported suicidal ideation after graduation from veterinary school (compared with those who did not) (OR = 1.83); Men were statistically significant less likely than women to have negative attitudes toward social support (OR = 0.72, p < 0.05). All respondents with negative attitudes toward social support were statistically significant more likely to be sole practitioners of veterinary medicine (OR = 1.23); to not belong to a veterinary association (OR = 1.29); to exhibit signs of serious mental health problems (OR = 1.55); to report suicidal ideation after graduating from veterinary school (OR = 1.66); and to be 40 to 59 (vs. 20 to 39) years old (OR = 1.18) (p < 0.05).
In their study, Kogan et al.  addressed the assessment of the prevalence of medical errors in the practice of veterinary medicine (near misses = NM, adverse events = AE) and the personal and professional impact on veterinarians (N = 606). Seventy-four percent (73.8%) of respondents reported having been involved in more than one NM (64.2%) or AE (29.5%). Following the most severe AE with which they had been involved, 42.4% felt less satisfied with their job, 37.7% felt burned out, 65 36.9% had a decrease in overall happiness, 35.1% felt that their professional reputation had been negatively impacted, 33.7% had problems sleeping, and 33.5% felt persistently guilty. Short term was defined as ≤ 1 week after the event and long term was defined as > 1 week after the event. NMs had a short-term (≤ 1 week) negative impact on professional life in 68.0% of respondents and a longer-term negative impact in 36.4%.
Mair et al.  used the Warwick-Edinburg Mental Wellbeing score (WEMWBS) to assess the mental wellbeing of equine veterinarians (N = 451) (as well as equine nurses and veterinary students) during and before the COVID-19 pandemic. The results of the 14 individual items of the WEMWBS for veterinary surgeons and veterinary nurses, and the mean total scores, were compared to the results for equine veterinary surgeons and equine veterinary nurses from the 2019 survey of the veterinary profession The mean WEMWBS score for veterinarians was 47.17 during the pandemic’ the mean score was 48.08 in a prepandemic 2019 survey . There were statistically significant differences for 9 of the 14 WEMWBS items between the sums of the number of respondents who answered “never” or “rarely” and those who answered “often” or “always” for the two surveys. The two proportions test revealed statistically significant differences between the proportions of respondents who answered ”often” and ”always” for 8 items and statistically significant differences between the proportions of respondents who answered ”rarely” and ”never” for 8 WEMWBS items (there were statistically significant differences in both proportions tests for 6 items).
Mastenbroek et al.  tested the role of three personal resources (proactive behavior, reflective behavior, and self-efficacy) in the Job Demands-Resources (JD-R) model to predict self- and external assessment of performance of veterinarians (N = 860). The direct effect of job demands on self- and external assessment of performance in the role was statistically significant. Work demands were positively related to exhaustion. Exhaustion was negatively related to self- and external assessment of performance in the role.
Nett et al.  surveyed the prevalence of suicide risk factors, attitudes toward mental illness, and practice-related stressors among US-American veterinarians (N = 11.627). Nine percent of respondents suffered from severe mental health problems, and 31% of respondents had depressive episodes since completing veterinary school. At the time of the survey, 19% of respondents were receiving treatment for a mental illness. The most frequently cited practice-related stressor was the demands of practice. The mean Kessler 6 (K6) score on risk factors for suicide was 6.0, and 17% of respondents had suicidal ideation, with 1% having attemptedsuicide (since leaving veterinary school).
In a cohort study consisting of US Army medical professionals, Rivera et al.  examined the determination of the prevalence and relative likelihood of, among other things, mental health problems, suicidal ideation, and lack of social support among veterinarians (N = 101) compared with others (nontrauma physician, trauma physician, general dentist, veterinary technician, or medic). The results of logistic regression analysis showed that veterinarians were more likely to experience psychological problems than general dentists (OR = 2.53). Compared with physicians and dentists combined, veterinarians also had a higher likelihood of experiencing psychological problems (OR 1.89); sleep disturbances (OR = 2.07); and lack of social support (OR = 1.68). A total of 36.6% of veterinarians reported a lack of social support; and 52.5% reported problems falling asleep.
Schwerdtfeger et al.  examined the risk of suicide and depression among German veterinarians (N = 3,118) and compared the results with two general population samples of the same age group (mean age 41.3 years) using the Suicide Behaviors Questionnaire-Revised (SBQ-R) and the Patient Health Questionnaire (PHQ-9). Approximately twenty-eight percent (27.78%) of veterinarians were found to have depression according to the PHQ-9, of which 17.45% had moderate symptoms of depression and 10.33% had moderately severe to severe symptoms of depression. Compared to the general population, veterinarians are approximately three times more likely to have depression (OR = 0.349; 95% CI 0.309 to 0.940). Nineteen percent (19.2%) of the veterinarians studied were classified as having suicidal ideation in the past two weeks; and the majority of those patients (15.91%) reporting to have had such feelings on several days during the last two weeks; 2.31% reported almost half of the days; and 0.96% reported nearly every day in the past two weeks. Veterinarians were approximately twice as likely to express current suicidal ideation as the general population sample used (OR = 0.497; 95% CI 0.445 to 0.554). Using the SBQ-R, 32.11% of veterinarians were classified as having an increased risk of suicide (compared with 6.62% of the general population); veterinarians showed a six- to sevenfold-fold higher risk of suicide than the general population according to the SBQ-R (OR = 0.150; 95% CI 0.123 to 0.183).
Schwerdtfgeger et al.  published some results in the German Veterinary Journal and extended these datafrom the COPSSOQ . Emotional exhaustion was more common in women (“always”: 5% or ”often”: 36%) than in men (“always”: 5% and “often” 25%, respectively). Clinically relevant depressive symptoms were identified in 27.8% of respondents.
Witte et al.  compared the prevalence of negative mental health outcomes among lesbian, gay, bisexual, transgender, queer, questioning, and asexual (LGBTQ +) veterinary students and veterinarians (N = 440) with the prevalence reported in a previous study from Nett et al. . The lifetime prevalence of suicidal ideation and suicide attempts was also higher (29% of nonheterosexual cisgender individuals (cis describes a person whose gender identity is the same as their sex assigned at birth), 36% of nonheterosexual cis veterinary women, and 50% of transgender or nonbinary veterinary individuals) than those reported as comparative values from the study results of Nett et al. . Transgender and nonbinary individuals had a statistically significantly higher prevalence of severe mental disorders (Kessler 6 score ≥ 13) at 41% than the comparison groups (p < 0.01). Nonheterosexual cis women (16%) had a statistically significantly higher prevalence of severe psychological distress than female veterinarians (p = 0.005). Transgender and nonbinary individuals showed the highest prevalence of previous depressive episodes (50%), which differed statistically significantly from the prevalence for male veterinarians (p = 0.001) and for nonheterosexual cis men (p = 0.01). Nonheterosexual cis women had a statistically significant (p = 0.003) higher prevalence of previous depressive episodes (45%) than female veterinarians in the comparison study.
Quality assessment (EPHPP)
All studies were rated as weak; only one study was a longitudinal study (Rivera et al. 2021) , and there was no blinding. Due to the study types, there were also weaknesses in selection bias. The majority of studies considered confounders, so a strong rating could be assigned for this aspect [13, 21, 36,37,38, 41, 43,44,45, 47, 48, 50, 52]. The study drop-out item was not applicable to any of the studies. Evidence from the included studies is not indicated.
In this section, the current scoping review is summarized on the basis of the search results, and then, the main findings are compared to similar research articles. The limitations of this scoping review are also described. Finally, recommendations for practice are presented. The present scoping review aimed to summarize studies on psychological workload and its possible related health consequences in veterinarians. The results of the studies presented here indicate a very wide variety of mental health outcomes within the veterinary profession (for example, depression, burnout, anxiety, and suicidal risk factors). Therefore, despite a broad search strategy, it is possible that not all studies appropriate for this review were identified. Furthermore, the search could have been expanded to include terms related to occupational health (for example, compassion fatigue). Nevertheless, 21 studies (plus seven additional studies without a standardized questionnaire) from nine countries (England, USA, Canada, Australia, New Zealand, Germany, Finland, Turkey, Netherlands) were found. This again highlights the increasing number of publications and related research on the topics of suicide, burnout, and depression among veterinarians, as described by Brysk et al. . The studies were assessed according to EPHPP and were classified as weak according to the existing guidelines. Although the EPHPP evaluation tool is suitable not only for randomized controlled trials or controlled clinical trials but also for cohort or other studies, only weak study qualities were achieved, as expected. Therefore, the need for further studies, such as intervention studies investigating the effect of preventive measures, arises here as well.
The results of the studies indicate an increased prevalence of psychological stress factors and conditions among veterinarians, highlighting risk factors for mental health, such as burnout, anxiety and depressive disorders. Taking a gender-specific view of the studies presented, female veterinarians tend to have poorer mental health than male veterinarians. The higher proportion of women in veterinary medicine should be taken into account . Epidemiological studies in recent years have found that the prevalence of depression is generally higher in women than in men . The comorbidity of anxiety and depression was identified as a risk factor for suicide in veterinarians by Nett et al. . In Shirangi , longer work hours were associated with increased anxiety and depression in female veterinarians overall and subdivided by women with and without children. Similarly, the aforementioned review by Platt and colleagues  indicates that female veterinarians are most at risk for negative stress outcomes such as suicidal ideation, mental health problems, and job dissatisfaction. In this respect, work-life balance among female veterinarians should be focused on at the organizational level. Hatch et al.  infer from their data that increased anxiety occurs in employees who have practiced veterinary medicine for 10 to 15 years. This is explained by the association of increasing responsibilities in the practice but also with increasing family responsibilities, which are often assumed by female veterinarians. These include, among other things, the reconciliation of working hours and family. Longer working hours were associated with increased anxiety and depression in Shirangi’s study of female veterinarians both with and without children (Shirangi et al. 2013) . Findings related to the LGBTQ + population by Witte et al. (2020) suggest a higher likelihood of negative mental health outcomes than among veterinarians in general. Within the LGBTQ + respondent sample, transgender and nonbinary individuals have the highest risk of negative mental health outcomes, and nonheterosexual cis men have the lowest risk . Further research is recommended to ensure that LGBTQ + affiliated veterinarians receive appropriate support.
The MBI (including the MBI-HSS) questionnaire (Maslach and Jackson 1981)  was used four times as the most common survey instrument in the studies presented. In a study conducted by Heath  among veterinary students, burnout as assessed by the MBI decreases with increasing years after veterinary school but still exceeds 25% of the reference data for personal burnout compared to work-related burnout, which approaches the reference values (reference baseline data are from the 2001 ABS Health Survey of the Australian population ) (Hatch et al. 2011) . That burnout decreases with increasing years after graduation has also been described by Reijula et al.  in their study. There, too, in the estimation the overall prevalence of work-related burnout (with the MBI), 40% were found to have moderate symptoms and 1.7% severe symptoms. The classification of burnout risk according to the three MBI subscales (according to Maslach) showed an 8.8% high risk in a study with hospital doctors. Another 11.8% of the participating doctors showed a moderate risk of burnout . Similar results were found for the burnout prevalence of anesthesiologists . This implies a higher risk of burnout than in human medical professions.
The concept of resilience is becoming increasingly important in relation to protective health factors , as people with high resilience show fewer burnout symptoms and fewer consequences of mental and psychosomatic illnesses . The results of the CD-RISC scale, which was developed by Best et al. , indicate that the scores of 74.5% of the veterinarians studied are below the scale’s (general population of the United States) comparison norm of 80.7% ., Mental and physical health emerged as strong predictors of resilience among veterinarians in the study by Perret et al. . Considering that veterinarians are also exposed to enormous physical hazards [91, 92] and have a high incidence rate of occupational injuries, which is more than double that of doctors of human medicine , prevention and support services should address both mental and physical health.
In Fritschi et al. , participants reported increased levels of work stress and distress due to working hours. The veterinarians studied by Reijula et al.  considered a reduction in working hours or a reduction in on-call duty to be suitable means of reducing stress. A major stress factor among veterinarians is working time. In an older study (survey from 1999, therefore not included as part of this review) by Gardner et al. , working hours were considered to be one of the main stress factors in veterinary practice.
Depression is generally among the most frequently cited risk factors for suicidal behaviors  and is frequently referenced in risk factor guidelines of national and international organizations and included in structured suicide risk assessments . In a qualitative study by Waters , small animal veterinarians in the greater Seattle area were interviewed about their professional experiences related to depression, suicidality, and coping. Analysis of the interviews revealed that attachment loss and trauma were the most important factors contributing to depression and suicidality within the veterinary profession (Waters et al. 2019). A study by Schwerdtfeger [13, 51] was the first to compare German veterinarians with the German general population in terms of depression, suicide risk, and suicidal ideation. The analyses indicate that veterinarians have a statistically significant increased risk for depression and suicidal ideation compared to the general population in Germany. The results of the review indicate a disproportionate incidence of depression among veterinarians. This indicates the urgency of implementing appropriate measures and interventions to reduce depression and suicidality among veterinarians.
These findings of our scoping review highlight the importance of reducing psychological stressors to increase the overall mental wellbeing of this population group and improve the mental wellbeing of veterinarians. There is a need for further studies, such as intervention studies investigating the effect of preventive measures.
Strategies for coping with work-related stress in veterinarians should be developed in a timely manner. This includes gender-differentiated strategies to offer female veterinarians adequate methods of organizing work routines as well as reinforcement of social support. Furthermore, it is necessary to identify concrete work stresses in further surveys. For this purpose, further research is necessary that includes the requirements of emergency and on-call services as additional potential stress factors. Coaching and counseling on communication and conflict management, as well as courses/seminars on stress management, may be helpful to better learn how to manage stress, especially after critical deployments (for example, complex operations, complicated cases of illness, potential for conflict among pet owners). Support services such as counseling centers and mentoring programmes for early career professionals should also be made available.
Interventions aimed at the veterinary profession have been described by Bartram et al. (2010), which can be well derived from the results we have described . The authors refer to areas such as mental health promotion (e.g., mental health education initiatives integrated into the curriculum), monitoring of trends (e.g., implementation and monitoring of interventions), accessible and appropriate support services (e.g., introduction of a telephone counseling service), other personal and work-related stressors (for example, training to improve communication skills), work-home interaction (for example, forming on-call collaborations with local practices), or future research (for example, mixed methods or qualitative interviews with individuals experiencing suicidal ideation to perceive barriers to seeking help).
Professional organizations and veterinary schools should provide training on managing work-related anxiety and depression, as well as resilience-building programmes to improve the mental wellbeing of veterinarians and potentially reduce turnover in this profession. According to the American Veterinary Medical Association’s (AVMA) 2020 Veterinary Census report, poor work-life balance is the top reason to leave the veterinary profession: encourage parental support or hire relief vets to balance workload.
Several strategies can create a better work environment, improve employee retention and boost morale and wellbeing. Platforms such as the Mind Matters Initiative (MMI), which aims to improve the mental health and wellbeing of veterinary staff (including veterinary surgeons), can be helpful for this .
