Introduction

Doctors and nurses are of interest to researchers studying stress and burnout [1]. Researchers have shown that doctors and nurses alike are tired and overburdened with work challenges, such as high patient load and ethical, medical, and legal responsibilities [2, 3]. Reported burnout levels have been reported to be often higher than 50% [4-9]. Fatigue and overload are also characteristics of nurses whose burnout stems from socioeconomical factors, as well as hours of work, numbers of patients, job title, and level of education [8, 10, 11]. Researchers see burnout as a serious problem and one of the greatest threats of the 21st century in almost every work environment [12]. The causes of burnout are largely rooted in healthcare organisations and systems and include excessive workloads, inefficient work processes, office workloads, balancing home and work responsibilities, lack of organisational support, low professional status, and leadership. Individual factors also play a role, with higher burnout rates often being reported by women and younger doctors [12, 13]. There is an established link between high levels of stress and subsequent burnout [14]. Research on stress shows that it is a predictor of burnout; therefore, the problems of burnout syndrome are most often analysed from the point of view of stress theory, i.e. the long-term overload that results from continuous attempts to solve difficult situations, and to meet one’s own expectations and environmental requirements [12].
According to Maslach [12], to describe the burnout syndrome, it is necessary to characterise 3 main elements, the first of which is emotional exhaustion. According to Maslach, the most stressful is the first of the symptoms of the burnout process, identified with excessive emotional strain due to the intensity of interpersonal contact. It manifests itself as discouragement from working, gradual decrease of interest and involvement in professional matters, reduced activity, and constant tension, leading to psychosomatic manifestations such as headaches, insomnia, and immune suppression, resulting in illness.
The second element of burnout is depersonalization, i.e. indifference and distancing from other people, superficiality, cynicism, and blaming others for failure. Depersonalisation, in other words, can be described as objectification, i.e. treating people/patients as cases and thus protecting themselves from involvement in relationships. This behaviour protects depleted personal emotional resources. Depersonalisation can be seen either as a way of dealing with emotional exhaustion or as a consequence of it. The third component is a reduced sense of personal achievement characterised by dissatisfaction with one’s achievements, a sense of incompetence, a sense of being misunderstood, an inability to adapt to possible changes in the working environment, an inability to solve problems, conflict, and irritability. A reduced sense of personal achievement also refers to a loss of job satisfaction, blaming oneself for powerlessness, and low self-esteem. In extreme situations, aggressive reactions may be triggered, and escape reactions may also occur, such as frequent work absences [12].

Material and methods

The aim of the study was to compare professional burnout in groups of male and female doctors, and female nurses, and related coping strategies. The study was conducted in the Department of Anaesthesiology and Intensive Care in the Emergency and Disaster Medicine Trauma Centre (CUMRiK) in Krakow. The study involved 119 participants employed in the Anaesthesiology and Intensive Care Unit. The first tool used in the study was the Maslach Burnout Inventory (MBI) questionnaire, used to assess burnout syndrome [15, 16]. The questionnaire consists of 22 items concerning feelings about one’s profession. Each question is part of 1 of 3 separate subscales, which are emotional exhaustion, depersonalization, and sense of personal achievement. A high score on the subscale of emotional exhaustion and depersonalisation, and a low score in personal achievement indicates high burnout.
A second tool was Charles Carver’s Mini-COPE questionnaire, adapted by Zygfryd Juczyński and Nina Ogińska-Bulik, containing 28 statements reflecting the response of respondents to stressful events, which measures the styles of dealing with stress (coping). The tool has been deemed reliable and accurate [17]. A 4-point scale is used, in which 0 means I almost never do so to 3 – I almost always do so. The scales are evaluated separately. The Mini-COPE tool is used to examine 14 strategies focused on the problem and on emotions, including: 1. Active coping, 2. Planning, 3. Positive re-evaluation (perceiving the problem in a more favourable light), 4. Acceptance, 5. Humour, 6. Religion, 7. Emotional support seeking, 8. Instrumental support seeking (looking for advice and help from others), 9. Substitute activities (dealing with other activities to divert attention from a difficult situation), 10. Denial, 11. Discharging, which is about revealing negative emotions, 12. Substance use, 13. Stopping activities is interpreted as giving up efforts to improve the situation, and 14. Self-blaming [17]. Statistical analysis of the data was carried out using the Kruskal-Wallis test. The significance level for the test was set at a = 0.05.

Results

The study involved 119 participants employed in the Anaesthesiology and Intensive Care Unit, including 37 male doctors (30.5%), 23 female doctors (19.5%), and 59 female nurses (50%). The average age of the male physicians was 36.08 ±8.78 years (25-56), for female physicians it was 37.96 ±7.49 years (26-48), and for female nurses it was 34.53 ±8.12 years (23-61). Statistically significant differences in the assessment of personal achievement between a group of male doctors, female doctors, and nurses were shown (p < 0.001). According to post-hoc tests, statistically significant differences were found between the female physicians and nurses (p = 0.001) and between the male physicians and nurses (p = 0.008). The other MBI questionnaire scales did not differ significantly among the studied groups. The results are presented in Table 1.
Regarding the Mini-COPE questionnaire, statistically significant differences emerged in sense of humour among the male doctors, female doctors, and nurses (p < 0.001). According to the post-hoc tests, statistically significant differences were found between female medical doctors (MDs) and nurses (p = 0.011) and between female and male doctors (p < 0.001). Turn towards religion also differed significantly in the studied groups (p = 0.008), specifically between male doctors and nurses (p = 0.006). The Kruskal-Wallis test showed statistically significant differences on denial among the three groups (p = 0.035). Post-hoc tests indicated a tendency for differences between male physicians and nurses, approaching statistical significance (p = 0.065). In the remaining scales of the Mini-COPE questionnaire, no statistically significant differences were found. Results are presented in Table 2.

Discussion

Statistically significant differences in professional burnout and coping strategies between doctors and nurses were shown. No such differences were found between male and female doctors, which indicates that it may be the function performed, rather than gender, from whence stemmed the differences. Gender has been found as a significant predictor of burnout among nurses in Iran [18], while in Romania, neither age nor sex were predictors of burnout among intensive care unit (ICU) staff [19, 20]. In the present investigation, nurses showed a lower ability to deal with stressful situations than doctors. Occupational stress plays an important role in job burnout and quality of life among female nurses and female doctors, even after taking into account other potentially influencing factors [21]. In our research, the MDs scored higher on the burnout scale than nurses. However, this has not always been the case in previous studies [22, 23]. CUMRiK is a stressful place to work, with a lot of responsibility and a need for quick decisions for trauma patients.
Higher status healthcare workers like physicians and nurse practitioners are more likely than their colleagues to report work-life conflict, irregular work hours, and heavy work pressure. These stressors explain the higher levels of burnout found among physicians and nurse practitioners in the current study. In one Brazilian study, ICU nurses did not report high burnout [24], but Brazilian ICU doctors were highly stressed [25]. Collectively, our results lend support to “the stress of higher status” hypothesis and provide insights into the job demands and mental health issues confronted by today’s medical workforce [26].
Our groups differed in their strategies for dealing with stress. Male doctors, more often than other groups, used humour as a way to relieve negative emotions. Female nurses, in turn, used this strategy more often than female doctors. At the same time, nurses more often sought emotional support in religion, and for them it was a way to reconcile difficult situations. Studies in Asia have confirmed the protective effect of religion among doctors and nurses [27]. Nurses in the present study often used denial, which is based on ignoring a stressful situation. However, in this case, it is a trend, not a statistically confirmed correlation.

Conclusions

The results show that there are differences in the level of burnout and coping strategies in the groups of doctors and nurses. Thus, this may have serious consequences for the decisions made by medical staff, which will translate into the quality and effectiveness of treatment.
This may be related to the feeling of inferior education and perceived lower social status of nurses. It is important to adopt different preventive measures to prevent burnout and improve quality of life among the 3 groups, according to different stressors [21]. Interventions aimed at addressing the welfare and psychological needs of health care professionals should be promptly implemented by the hospital management, with a view to reducing psychological distress [22]. It seems to be important to provide training and preventive programs in “mixed” groups of both physicians and nurses, which would positively influence coping strategies and would increase trust and team cohesion.
