Abstract
Materials and Methods: Following the approval of the local ethics committee, 298 professionals were included in this cross-sectional survey study conducted between 01 December 2016 and 31 March, 2017. In addition to the 26 questions examining socio-demographic and work life sent via e-mail, participants were also sent the Work-Related Strain Inventory and the Maslach Burnout Inventory.
Results: 81.9% of the participants were male and the age average was found to be 42.0 ± 7.6 (26-63) years. Participants consisted of 112 specialist physicians, 47 research assistants, 29 doctor lecturers/chief assistants, 59 associate professors, 51 professors, while 40.9% were working in university hospitals. The study found that there is no difference in terms of gender in the subscales of Work-Related Strain Inventory and the Maslach Burnout Inventory (p = 0.564, 0.760, 0.359 and 0.579 respectively), and that the score from Work-Related Strain Inventory increased in line with increased academic status, while physicians working at the university got higher scores from Work-Related Strain Inventory (p ˂ 0.0001). It was established that research assistants, and thoracic surgeons working in state hospitals and teaching hospitals had high scores in the emotional exhaustion (p < 0.001) and depersonalization subscales (p<0.001) of the Maslach Burnout Inventory, while professors and those working in university hospitals had higher personal accomplishment scores (p < 0.012).
Conclusion: In the study, it was found that professors had higher point at Work-related Strain Inventory and personal accomplishment scores, whereas lower point at emotional burnout and depersonalization scores than in other academic titles. As a result, job-related strain was found to be significantly higher among academics with high workloads.
Introduction
Burnout syndrome (BS) is as common in our country as it is around the world. BS is a clinical condition that starts quietly, progresses slowly with the impact of certain factors, affecting first the mental balance of the individual, and when it goes unnoticed, it paves the way for psychosomatic disorders, and significant issues in work-family and social life in the future. It is reported that 80% of employees face this syndrome at any time in their work life [4]. This commonly observed condition adversely effects work life with its undesirable personal and organizational results [8].
In their report, the International Labor Organization has reported that BS is seen more frequently in occupational groups such as doctors, nurses, teachers, police, lawyers, who work face to face with people, directly serve people, and which the human element has a very important place in the quality of service [9]. In studies conducted in this area, it has been reported that there are many factors involved in the emergence of Burnout syndrome. In addition to individual characteristics such as age, gender, educational level, marital status, length of time in profession and seniority, the ability to use coping mechanisms, the effectiveness of organizational factors like workload, rewarding, control, belonging, justice, working time are also shown [9,10].
Medicine is an occupational group that manages the most sensitive periods of humans such as illness. Working face-to-face with people, tension caused by excessive patient load, uncertain and long working hours, insufficient hospital resources, problems in professional relations, dealing with chronic-fatal patients and patient relatives, economic concerns, inability to spare enough time for themselves and their private life lead to Burnout syndrome. In addition to these, the expectation from surgeons to think quickly and make critical decisions in the face of events, the pressure to avoid making mistakes increases the development of Burnout syndrome in this group [4].
Thoracic surgeons experience Burnout syndrome at equivalent rate to all surgeons (40% to 50%). Although more than 70% of thoracic surgeon members of The Society of Thoracic Surgeons report being satisfied with their career, surgeons are commonly affected by burnout (40%), though only a minority ever seek psychiatric or psychological help [11]. There are a few studies in the literature on burnout syndrome in thoracic surgeons [12,13]. Workforce Report from The Society of Thoracic Surgeons identified several characteristics common to thoracic surgeons at increased risk for burnout sendrom, including very long duration of residency training, high number of hours worked per week, frequent nights on call, and increasing caseload volumes [13].
Our hypothesis in this study is that the working conditions of thoracic surgeons affect work-related stress and burnout levels (emotional exhaustion, depersonalization, personal success).In this study, it was aimed to evaluate the work-related strain and burnout status of thoracic surgeons and research assistants working in our country.
Materials and Methods
Scales Used in the Study
Work-Related Strain Inventory is a 4-point Likert-type self-report scale consisting of 18 items that was developed by Revicki et al [14] in 1991 in order to determine work-related strain and stress in health workers. The scale was translated into Turkish and first applied to a nurse sample, and then to seven occupational groups working in the health field [15,16]. As item 15 significantly reduced the reliability coefficients in both studies, this item was removed from Aslan et al [8] study. In work-related strain inventory, the items are evaluated as “completely suitable for me”, “greatly suitable for me”, “partially suitable for me” and “not suitable for me at all”, and between 4-1 points. Items 2, 4, 8, 9, 11 and 15 are reverse scored. The lowest score on the scale is 18, and the highest score is 72. The strain increases as the score increases [8].
The Maslach Burnout Inventory was developed by Christina Maslach et al [1] and the reliability and validity of the Turkish version was prepared by Ergin et al [17] It consists of 22 questions, with each question containing five-digit answer options. It has three components: Emotional Exhaustion, Personal Accomplishment and Depersonalization. The EE and DP scales contain negative responses, while low personal accomplishment scale contains positive responses. Scores are calculated separately for each scale. Since there is no cut-off value for the scores obtained from the subscales, there is no discrimination in the form of exhaustion is present or absent. Individuals experiencing burnout are expected to have high EE and DP, and low PA scores [1,17].
Statistical Analysis
SPSS v21 was used to evaluate the data. When the age and scale scores obtained as a result of the study were evaluated using the Kolmogorov Smirnov Test in terms of suitability for normal distribution, it was found that they did not comply with normal distribution. Descriptive statistics were given as median (minimum-maximum), and the Mann Whitney U test was used to compare two groups to evaluate the data. The Kruskal Wallis Test was used in the comparison of more than two subgroups, and the significant parameters were compared with the Bonferroni corrected Mann Whitney U test. Statistical significance level was taken as p<0.05, and after the Bonferroni correction, it was taken as p < 0.01.

Table 1: The demographic features of participants.
Table 2: Data on the participants' working life, earn-ings and time spent with their families.
In terms of personal monthly incomes, at the time the study was conducted, 62.1% of participants were in the 5.000-10.000 TL range, while the monthly family incomes for 41.5% of participants were stated to be in the 10.000-15.000 TL range. 63.3% (n = 189) of participants stated that their monthly income was partially sufficient, yet 23.6% (n = 70) stated that it was insufficient. Table 2 is shown that, 83.5% of participants are married and 80.5% stated that they have children. The median number of children is 2.0 (0-4.0), and 19.5% (n = 58) of participants stated that they have people who need constant care and for whom they are obliged to provide care. When participants were asked to consider the time they allocate to themselves or their families, while 55.1% stated that this time was insufficient, 31.6% stated that it was partially sufficient.
Hundred seven (36.0%) of the participants stated that they had watch duty, and 188 (63.3%) had on-call duty. While the number of median watch duty on weekdays and weekends is 3 (1-11) and 2 (1-7) per month, respectively, the number of median on-call duty on weekdays and weekends was found to be 7 (1-30) and 3 (1-8) per month, respectively. 30.2% (n = 90) of the thoracic surgeons who participated in the study stated that they had a diagnosed disease. These diseases are hypertension (n = 27), cardiovascular diseases (n = 14), diabetes (n = 16), bone and joint diseases (n = 15), anxiety (n = 8), malignancy (n = 6), endocrine diseases (n = 5), and others (n = 22). 13.8% (n = 41) of participants stated that they have been using antidepressant drugs for the last 6 months.
The study’s scores for the subscales of WRSI and MBI according to some characteristics are shown in Table 3. While no statistically significant difference was found in the subscales of WRSI and MBI in terms of participants’ gender, choice of medical faculty and thoracic surgery based on their own will, there was difference in terms of the spouse’s employment status, their institution of employment, and title.

Work-Related Strain Inventory does not have a cut-off value, and the level of tension due to work increases in direct proportion to the score obtained from the scale. In the study, it was found that there was a difference between the hospital groups studied in terms of work-related strain score (p = 0.012), and the highest score was found in university hospital staff. In terms of the institution of employment, difference was found in Work-Related Strain Inventory between state hospital and training and research hospital staff (p = 0.006) and between state hospital and university hospital staff (p = 0.002). In terms of academic title, Work-Related Strain Inventory presented a difference between residents and professors (p = 0.011), thoracic surgeons and associate professors (p = 0.001), and thoracic surgeons and professors (p ˂ 0.0001). As in the institution studied, those whose academic degrees are associate professors and professors were found to have higher work-related tension (Table 3).
As the burnout increases in the Maslach Burnout Inventory, the score of the emotional exhaustion and depersonalization sub-dimensions increases and the personal achievement score decreases. When the Maslach Burnout Inventory results are analysed in this study, a statistically significant difference was found in all subtitles of the scale between those who held watch duty and those who did not (respectively 0.042, 0.047 and 0.001). It is found that there is a difference in the academic title in the emotional exhaustion subtitle in residents and thoracic surgeons is higher than the other academic titles. This result shows that emotional exhaustion of residents and thoracic surgeons is higher than other academic titles. In terms of the academic titles, difference was found in emotional exhausting between residents and professors (p = 0.011), thoracic surgeons and associate professors (p = 0.001), and thoracic surgeons and professors (p ˂ 0.0001); the emotional exhaustion subscale presented a difference between residents and associate professors (p = 0.001), residents and professors (p = 0.002), thoracic surgeons and associate professors (p = 0.002), and thoracic surgeons and professors (p = 0.002). The personal accomplishment subscale presented a difference between thoracic surgeons and associate professors; and the depersonalization subscale presented a difference between residents and thoracic surgeons (p = 0.004), residents and associate professors (p ˂ 0.0001), and residents and professors (p ˂ 0.0001). As in the institution studied, those whose academic degrees are associate professors and professors were found to have higher work-related tension (Table 3).
A difference was also found in personal accomplishment between instutiations (p = 0.030). Personal accomplishment score of those working in state hospital and training and research hospital is lower than those working in other institutions (p = 0.005). The personal accomplishment subscale presented a difference between thoracic surgeons and associate professors; and the depersonalization subscale presented a difference between residents and thoracic surgeons (p = 0.004), residents and associate professors (p ˂ 0.0001), and residents and professors (p ˂ 0.0001). In the last title, depersonalization, there is a difference in spouse’s working status and academic title, the score was found to be lower in participant that spouse not working and professors than in other groups (Table 3).
Discussion
Studies conducted in the world and in our country show that BS is a common problem among physicians. In a study conducted by Karamanova et al [21], the average EE and DP scores of healthcare workers from seven South and Southeast European countries were found to be 31.9% and 33.2%, respectively. In the same study, it was reported that Turkish healthcare workers had higher emotional exhaustion and depersonalization scores (53.8% and 58.9%, respectively). In a 2009 study conducted by Shanafelt et al [20] among surgeons, 7,905 members of the American Surgical Association participated in the study. It was found that 40% of the participants showed at least one of the symptoms of burnout, 32% scored high in EE, 26% scored high in DP, and 13% scored low in personal accomplishment. Similar results were found in other studies evaluating surgical branches. In a 2001 study evaluating 521 general surgeons and orthopaedic specialists established high burnout rate in both branches, and 32% of participants scored high in emotional exhaustion, 13% scored high in depersonalization, and 4% scored low in personal accomplishment [22]. In another study from our country, Bolat et al [23] reported that Burnout syndrome was common among urology specialists, that EE and DP, which are subscales of BS, were frequently observed, and that this had an adverse effect on the psychosocial condition of urologists.
In our study, it was found that there was no difference in terms of gender in the subscales of Work-Related Strain Inventory and the Maslach Burnout Inventory. Some studies in the literature have found that burnout is more prevalent in female physicians [24,25] while other studies found it was more prevalent in male physicians [26,27]. Similarly, in a study conducted by Özkula et al [18], no difference could be found between genders. The absence of a difference between genders may be due to the fact that the structure of today’s health system and heavy working conditions cause similar burnout in both genders regardless of gender. On the other hand, thoracic surgery residency being chosen more by men, and the lower number of female surgeons in the study may have affected this result.
Burnout syndrome occurs more frequently due to reasons such as intense work pace, heavy workload, and excessive watch duty particularly during the assistantship period, which is the first year of medicine. However, believing that all physicians experience similar problems during their assistantship period leads to this situation being recognized as a normal. In the long run, though, this situation leads to decreased job satisfaction and psychological problems. It is known that the rate of burnout specifically in surgical branches increases more compared to other branches as the number of work years increase [4,24]. In this study, approximately 90% of participants stating that they willingly chose both the medical faculty and thoracic surgery, with almost half of them stating that thoracic surgery specialty was among the top five choices in their MSE preferences shows that they chose their profession willingly. However, the study determined that the problems faced by physicians in the later years of their duration of work and their preparedness to cope with these problems caused changes in their decisions. As a matter of fact, only 1/3 of them stating that they would prefer thoracic surgery once more if they had the right to choose again, shows that they are experiencing problems in terms of professional satisfaction and BS.
More than half of the participants stated that the time they allocate to themselves or their family was insufficient. Moreover, 83% of the participants stated that they are married, 80% have children and 1/5 of them have family members who need constant health care and for whom they are obliged provide care. Physicians’ intense work pace, the uninterrupted service provided to patients, as well as the excessive number of watch and on-call duties on both weekdays and weekends prevents them from allocating adequate time for themselves and their family. A number of studies have reported that young age, having children, weekly working hours, the number of on-call duties, and sufficient financial opportunities are the individual risk factors related to burnout. In the same publications, only 36% of surgeons stated that they had enough time for themselves and their families [20,22,24].
While only 13% of participants found the wages received sufficient, it was established that the depersonalization score is higher in those whose spouse was not working. This shows that physicians have economic concerns and that this increases depersonalization. Sleep deprivation leads to deterioration in cognitive performance, memory, reaction time, and variation in circadian rhythm. As a result of sleep deprivation, increases risk of human error related accidents and increases work-related strain and burnout [12]. In this study, a statistically significant difference was found in all sub-titles of the Maslach Burnout Inventory between those who were watch duty and did not. Burnout was more common in those who had a on-call duty.
In studies which professional status is associated with work-related strain and burnout, it has been determined that those who are professors, associate professors or specialists scored significantly lower than assistants in Work-Related Strain Inventory and the Maslach Burnout Inventory. This is thought to be due to the decrease in professional uncertainty and concern for the future as professional status increases [28-30]. When the findings obtained from our research were examined, in stark contrast to the literature, it was found that the scores from WRSI increased as the academic status increased. It must be kept in mind that the result determined in the study may be related to reasons such as the intense communication of academics with students, intense pressures on them to publish and be successful, as well as pressures caused by the health system and performance system. In support of this finding, it was found that the thoracic surgeons working at the university got higher scores in WRSI. This result in the study group suggests that work-related strain may differ in studies conducted in different conditions and organizational structures.
In the study, it was found that research assistants, who have the lowest academic status, scored higher in the emotional exhaustion and depersonalization subscales of the MBI, in contrast to WRSI. Research assistants, who are in the early years of their specialty education, strive to cope with heavy working conditions on the one hand. While on the other hand, they are expected to take responsibility, make decisions and solve problems in patient management. When all these demands exceed one’s coping capacity, it can lead to emotional exhaustion. This causes depersonalization towards patients and the loss of occupational idealism [5]. Similar to the results In WRSI, it was found that emotional exhaustion and depersonalization scores were high among staff working at state hospitals and teaching hospitals. It is considered that this situation is associated with the failure of the thoracic surgeons working in state hospitals in our country to fulfil their duties sufficiently, thus leading to their loss of moral motivation.
Low personal accomplishment defines the tendency of the individual to consider themselves negatively, as a result of which they feel inadequate, think they are not a competent individual and their motivation decreases [2]. In the study, the personal accomplishment score was found to be higher in professors and those working in university hospitals. Rewarding in various ways the contributions those with high academic titles make to their institutions, making presentations in congresses and symposiums, showing both material and moral appreciation make the individual feel more successful and valuable. This is an important motivation tool for individuals. On the other hand, individuals being more autonomous in their work compared to others as the academic title increases, their ability to make and implement their decisions more freely, having initiative regarding their work boosts the feeling of PA and reduces burnout [2].
In the study, it was found that one-third of participants have chronic diseases, primarily HT, and 13.8% of them had been using antidepressant drugs for the last 6 months. When BS is not detected and prevented at the appropriate time, besides intangible losses such as job loss, financial losses, family problems, difficulties in social relations, and loneliness, it can also often lead to numerous psychiatric illnesses ranging from somatoform disorders with physiological and psychological symptoms to depression [5].
As a result, in terms of Burnout syndrome, healthcare professionals, particularly surgeons, are among the risky occupational groups today. Burnout is a problem that needs to be emphasized in order to protect the mental health of the individual and to intervene early when necessary. At an institution where burnout is experienced less frequently and employee job satisfaction is high, the quality of the health service to be provided will also be high. The professional and social measures to be taken by authorized institutions, primarily the Turkish Society of Thoracic Surgery, can help increase psychosocial well-being, reduce the incidence of burnout in thoracic surgeons, and improve health care quality. Furthermore, in order to obtain sufficient data on this subject, studies are needed in our country particularly in relation to determining effective methods in preventing and dealing with Burnout syndrome.
