Abstract
Background
Burnout, a measure of professional distress, is more common among medical professionals. About half of medical students have this problem. However, little is known about the burnout status of medical students in Ethiopia. Therefore, the aim of this study was to assess the prevalence and associated factors of burnout among medical students of Debre Berhan University (DBU).
Methods
A cross-sectional study was conducted on randomly selected 151 medical students of DBU. Burnout was assessed using the Maslach Burnout Inventory-Human Services Survey (MBI-HSS). Participants were reported as having burnout if they scored ≥27 on Emotional Exhaustion (EE), ≥13 on Depersonalization (DP) sub-scales, and ≤ 31 on Personal Accomplishment (PA) sub-scale of the MBI-HSS. EpiData version 3.1 was used for data entry while SPSS version 20 and STATA version 13 for windows were used for data analysis. Both univariable and multivariable binary logistic regression analyses were conducted. The degree of association between variables was assessed using odds ratio (OR) with 95% confidence interval (CI) at two-tailed p-value of < 0.05.
Result
Of 144 medical students took part, 34.0% had symptoms of burnout. Regarding domains of burnout, 61.8% scored high on EE, 47.9% scored high on DP and 59.7% scored low on PA. Dissatisfaction with practice lecturer (AOR = 3.8, 95% CI (1.3, 11.6)), moderate social support (AOR = 0.2, 95% CI (0.1, 0.8)), and satisfaction with their education (AOR = 0.1 95% CI (0.0, 0.7)) were associated with burnout.
Conclusion
More than one-third of medical students at DBU had burnout. Individual and organizational level interventions targeting students who had poor social support, dissatisfied by their lecturer at the hospitals and their education are recommended.

Background
Burnout is a measure of professional distress, which is thought to have three main domains: excess emotional exhaustion (EE), excess depersonalization (DP) and reduced personal accomplishment (PA) [1]. Burnout is increasingly reported as a common phenomenon among medical students, residents, and physicians with less than 5 years of experience compared to the general population [2]. This may be due to the heightened exposure to emotional strains given that they often interact with individuals who are physically and/or psychologically impaired. The prevalence of burnout among medical students ranges between 10 and 70% [3–16]. In the United States of America (USA), more than half of medical students are affected by burnout during their medical education [17].
Burnout among medical students has many consequences. Burnout is reported to be associated with job turnover, absenteeism, low morale and job dissatisfaction [18, 19]. Burnout may also be associated with some individual-level adverse outcomes, such as; poor decision making, hostility to patients, medical errors, poor relationships with colleagues, depression, anxiety and fatigue, sleep disturbances, alcoholism, drug misuse, and suicidal ideation [4, 14, 17, 20]. In addition, an increase in level of burnout showed a significant association with poor quality of life, and hypertension and other cardiovascular disorders [21–23].
Associated factors of burnout among medical student were increased year of education, presence of multiple adverse life events, stress, feelings of having limited control over life, poor peer interactions and support from friends, lower level of physical activity, smoking cigarettes, sex and excessive alcohol drinking [3, 6, 7]. Other studies found association between burnout and lack of confidence in once clinical skills, feeling uncomfortable with course activities, falling to see coursework as a source of pleasure, falling an examination, considering withdrawal from school and increased age. Moreover, having parents who are doctors, lack of supportive resources, having shortage of off-time, lack of belief in the importance of their work, fear of the consequences of failure, having family responsibilities, having an uncertain future, having a stress, and having increased workload are also reported to be associated with increased burnout level [8–10, 16].
In Ethiopia, very few studies were conducted on burnout and none of them were on medical students. These studies focuses on conceptualization of burnout among primary health workers [24], assessing factors that affect the motivation of health care workers [25], and burnout status and work-related stress of the health professionals working at hospitals [26, 27]. Medical students in Ethiopia are at a high stressful situation because of economic problems, which may lead to burnout. At Debre Berhan University (DBU), most medical students had added family responsibilities in addition to their education that may lead to burnout. In addition, medical students of DBU are recruited after having a bachelor’s degree and used to work at least for 2 years, as a result there might be role conflict when they were changed from employee to unemployed students. Those and other factors may increase the burden of burnout among DBU medical students to be higher than previously reported. Therefore, it is worthful to address this gap and manage burnout among medical students. Hence, this study aimed for assessing the prevalence and associated factors of burnout among medical students at DBU.
Methods
Study setting and period
This study was conducted among medical students at DBU from April 10 to 15, 2017. DBU is a public university located at Debre Berhan town, which is 130 km north of Addis Ababa, the capital city of Ethiopia. Department of medicine is one of the 33 departments at DBU, during the 2016/2017 academic year 213 medical students were enrolled.
Study design and population
An institution-based cross-sectional study was conducted among 151 medical students. The sample size was determined by applying a single proportion formula with the assumption of 50% prevalence of burnout, 5% marginal error, 95% confidence level, and 10% of non-response rate. A prevalence of 50% was used to maximize the sample size since there was no previous study in DBU. Sample size correction formula was also applied given that the total number of students at DBU is less than 10,000.
A stratified sapling technique was employed using student’s class year as a stratum. First the total sample size (i.e., 151) was proportionally allocated for each stratum, then a systematic sampling method was used to obtain the study participants from each class year. We used the students’ attendance sheet, at each class year, as a sampling frame. All medical students at DBU who were available during the data collection period and willing to participate were included, while students who were too ill to complete the questionnaire were excluded.
Measurement of variables in the study
Outcome variable
Burnout status
Burnout was the outcome variable. We have used the Maslach Burnout Inventory-Human Service Survey (MBIHSS) questionnaire to assess burnout. It is derived from the Maslach Burnout Inventory (MBI), designed for professionals in the human services. It is also appropriate for respondents working in a diverse array of occupations, including medical students. It contains 22 questions which ask participants to indicate the frequency of various feelings experience. Each question has a six-point response scale (0: “never”, 1: “a few times a year or less”, 2: “once a month or less”, 3: “a few times a month”, 4: “once a week”, 5: “a few times a week”, and 6: “every day”), and is designed to measure the three domains of burnout; i.e., EE, DP, and PA. EE is characterized by feelings of emotional overextension as a result of one’s work, DP is characterized by emotional indifference and the dehumanization of the recipients of one’s services, and PA is characterized by feelings of occupational stagnation, incompetence, and underachievement. Scores in each of the three subscales were categorized into high, average, or low scores according to cut-offs detailed in the MBI manual [28, 29]. High EE is indicated by a score ≥ 27, high DP is indicated by a score ≥ 13, and low PA is indicated by a score ≤ 31. Participants were identified as having a burnout if they scored high in EE and DP, and low in PA. The MBI-HSS is a reliable and valid instrument to assess burnout [28, 29]. A previous study has indicated that even when used in another language (Spanish) the instrument produced high sensitivity and specificity, 92.2 and 92.1% respectively [30].
Exposure variable
The exposure variables were selected based on previous studies report [3, 6–10, 16]. We categorized exposure variables into socio-demographic and economic information, academic and work-related factors, social support and level of satisfaction in life, personal life experiences, leisure time, and family-related factors, and substance use habit.
Socio-demographic and economic information
Socio-demographic and economic information were assessed using a self-structured questionnaire, which had 11 questions concerning the sex, age, field of study, relationship status, ethnicity, religion, and economic status of the students.
Academic and work-related factors
Eighteen questions were used to assess academic and work-related factors that might increase the risk of burnout. The items in this section assessed the learning environment, comfort with the teaching-learning process, relationship with seniors, perceived flexibility of the curriculum, and exposure to suffering.
Social support and level of satisfaction in life
Social support was measured by the Oslo 3-items social support scale. The score ranges from 3 to 14. Score of 3 to 8 indicate poor support, 9 to 11 indicate moderate support, and 12 to 14 indicate strong support. The Oslo-3 scale has been used in previous studies and confirmed as feasibile and valid tool [31–33]. Level of satisfaction in life was measured based on the worst week of the last month using a question that is rated from very poor to very good.
Personal life experiences, leisure time, and family-related factors
Nine questions were used to assess personal life experiences, leisure time, and family-related factors. Questions included were uncertainty about the future, family responsibilities, and perceived adequacy of the amount of off-time and satisfaction with the study and clinical skill.
Substance use habit
Nine questions were used to assess the frequency of use of commonly available substances around Debre Behan, such as cigarettes, alcohol, and khat (i.e., an amphetamine-like substance common in Ethiopia).
Data collection procedure
After obtaining informed consent, the data were collected using self-administered questionnaire in English language. Trained students and supervisors who have previous experience of facilitating data collection. Confidentiality was ensured for all the study participants throughout the data collection process. The respondents were encouraged to respond to all items in the questionnaire as completely as possible.
Data analysis
Double data entry using EpiData version 3.1 for Windows was performed after checking for completeness and inconsistencies. Afterwards, the data were analyzed using SPSS version 23 and Stata Version 13 software packages for Windows. A comma-delimited file (*.csv) file of cleaned raw data was available and supplemented as an additional file 1. The data were summarized using mean, standard deviation (SD), or percentage and the results were presented using tables and figures. While the instrument used in this study has previously been proven reliable and valid, we also conducted a reliability analysis for our scale. Associations between dependent and independent variables were tested using the odds ratio (OR) with 95% confidence interval (CI) in the univariable and multivariable binary logistic regression analysis. Variables with a p-value of ≤ 0.05 in the univariable model were included in the multivariable model. All variables with a p-value of < 0.05 in the multivariable model were considered as statistically significant.
Results
Socio-demographic and economic information
Of the 151 medical students invited, 95.3% (n = 144) students participated. The most common reason of non-participation was shortage of time.
As illustrated in the Table 1, 85.4% (n = 123) were male, 68.1% (n = 98) were from Amhara Ethnic background, 63.2% (n = 91) were single, and 27.1% (n = 39) were fourth year, students. In addition, 78.5% (n = 113) of the participants perceived that their income was not enough.

Reliability of MBIHSS
The internal consistency of the instrument was very high: α = 0.90 for EE subscale, α = 0.86 for DP subscale and α = 0.90 for PA subscale. In any of the sub-scales, the α for correlated item-total correlation was not less than 0.4 and removing items does not significantly improve the overall internal consistency. In addition, two-way mixed-effects model and average consistency measure were used to measure the intra-class correlation of items. In all sub-scales, the intra-class correlation were significant with an intra-class correlation of 0.90 (95% CI = 0.88, 0.92) for EE sub-scale, 0.86 (95% CI = 0.82, 0.89) for DP sub-scale, and 0.90 (95% CI = 0.88, 0.93) for PA subscale.
Prevalence of burnout
Based on MBI-HSS definition, 34.0% (n = 49) of the study participants was found to have symptoms of burnout. The burnout prevalence incrementally increased with each additional year of school until 4th year and then starts to decline. Pertaining to sub-scales of MBI-HSS, 61.8% (n = 89) of the study participants scored high on EE sub-scale, 47.9% (n = 69) of the study participants scored high DP sub-scales, and 59.7% (n = 86) of the study participants scored low on PA sub-scale (Figs. 2, 3 and 4).

Factors associated with burnout
Female sex, being a 2nd year student, dissatisfaction with practical lecturers, not reporting administrative problem, perceiving paediatrics and emergency department as a stressful unit, being not comfortable with night duties, poor social support, very good overall life satisfaction, poor level of satisfaction on education, and not performing regular physical exercise were significantly associated with burnout in univariable model at p-value of < 0.05. However, perceiving paediatrics department as a stress full unit, being not comfortable with night duties, overall life satisfaction, and not performing regular physical exercise were removed from the multivariable model given that the observation per subgroup was less than five individuals.
All variables with a p-value of ≤0.05 in univariable model and with more than five observations per subgroup were included in the multivariable model. After controlling for the effects of potential confounding variables, dissatisfaction with practice lecturers, poor social support, and poor satisfaction on the education were significantly associated with burnout.
Students who were not satisfied by their practical lecturers were almost four times more likely to develop burnout than those who were satisfied (Adjusted Odds Ratio (AOR) = 3.8; 95% CI (1.3–11.6)). On the other hand, students who had moderate social support were 80% less likely to develop burnout than their counter parts (AOR = 0.2; 95% CI (0.1–0.8)). Additionally, students who had good levels of satisfaction on their education were 90% less likely to suffer from burnout than those who had poor satisfaction on their education (AOR = 0.1; 95% CI (0.0, 0.7)) (Table 7).

Discussion
This study aimed to determine the prevalence of burnout and to identify factors associated with burnout among medical students at DBU. The study demonstrated that 34.0% of medical students at DBU had symptoms of burnout. Burnout was significantly associated with reporting being less than satisfied by practice lecturers, having poor social support, and being less than satisfied by the education system.
Our finding on the prevalence of burnout is similar with the results reported in Jimma referral hospital health professional, Ethiopia (36.7%) [26] and Pakistan medical students (30.6%) [10]. On the other hand, our finding was lower than the prevalence report among medical students in the US, India, Malaysia, and Saudi Arabia, (45 to 70%) [3–5, 11–13], while higher than the report of less than 27% in United Kingdom (University of Saint Andrews, and University of Manchester), and Brazil (Fortaleza medical school and Universidad Federal de Sergipe) [7–9]. Some of the possible reasons for these differences might be due to the difference in culture, socioeconomic status, and study population. Some of the studies only included third- and fourth-year medical students while our study included students from the first year to graduate class students. Additionally, the different in burnout assessment tool and sample size may contributed to this discrepancy. Besides medical students of DBU came from being employed to an unemployed student which may contribute to the difference in the prevalence of the burnout status.
In agreement with previous studies [3, 6, 8, 10], we found that dissatisfaction by practical lecturers, moderate social support, and satisfaction on their education significantly associated with burnout. In this study, burnout was not significantly associated with gender, years of education, stress, little control over life, lower level of physical activity, cigarette smoking, excessive alcohol drinking, lack of confidence in clinical skills, age, shortage of off-time, fear of the consequences of failure, family responsibilities, uncertain future, and increased workload. However, other studies [3, 6–10, 16] found significant association between these factors and burnout. This variation may be due to difference in study population, sample size, culture and socioeconomic status. Most of the students in our study were male and between the age of 24 and 38 years. The small sample size of our study might not allow us to explore the factors associated with burnout.
In this study, there are several areas showing dissatisfaction with the course, which might explain why burnout is more prevalent among medical students of DBU. Theoretically, burnout is defined as a measure of professional distress with three main domains: excess EE, excess DP, and reduced PA [1], all this three domains might be directly or indirectly related to satisfaction. It is found in this study that dissatisfaction with the course in medical students at DBU is the main reason for the higher prevalence of burnout at this population. The findings here may be generalizable to other areas in the world, and dissatisfaction with the course may explain why burnout is more prevalent among medical student in general.
We measured burnout using a standard tool with demonstrated reliability and validity. To our knowledge, this is the first study that assessed burnout among all class years of medical students in Ethiopia. Our findings may be generalizable to other low- and middle-income countries. Despite these strengths, this study has the following limitations. First, we noticed instability in the the multivariable model that may be related to the sample size. To optimize the model, we removed variables with a small observations from the multivariable model. Second, the cross-sectional nature of the study does not allow attribution of causality inference. Finally, the tool was not validated in our study population although we revealed excellent reliability, future validation might be required.
The results of this study would have implications for developing an intervention strategy to promote the mental health of future doctors and to maximize the benefit of medical doctors on the health care system. Additionally, this study may provide a platform to develop evidence-based interventions for students experiencing burnout. Moreover, this study will serve as a baseline for government agencies (such as Ministry of Health), non-governmental organizations, policymakers, and health planners for future planning and interventions of appropriate strategies. Finally, the findings may be helpful for medical schools to help improve their students mental health.
Conclusions
In summary, this study reported a high prevalence of burnout among medical students of DBU, Ethiopia. Dissatisfaction with the course found to be the strong predictor of burnout. The college of medicine, Debre Berhan referral hospital, and the student clinic of DBU should undertake integrated interventions to tackle the effects of burnout on students’ academic performance. The high prevalence of burnout also suggests that immediate preventive, curative, and promotive measures to be implemented. It is believed that a significant proportion of students with burnout may be also at risk of getting depression or other mental health problems including suicide. Therefore, addressing both the mental and social well-being of future doctors needs to be a priority for the medical school administration. Furthermore, further research is recommended to validate the measurement tools for burnout in Ethiopia. Future studies are also recommended to investigate the longitudinal change in burnout symptoms and its effect on the educational attainment of students during their entire medical study period.
