This study aimed to assess the point prevalence and to explore factors associated with emotional exhaustion (EE) among medical doctors in Iraq. Methods: Descriptive and a cross-sectional study was conducted (January to June 2014) among a randomly selected sample of medical doctors (n=576, 87.3% response rate) working in twenty large general hospitals and medical centers. In addition to EE, the self-administered questionnaire used was consisting of questions on sociodemographic, work-related characteristics, conflict-related variables, and job satisfaction. EE was measured using the emotional exhaustion subscale of the Maslach Burnout Inventory (MBI). Results: The prevalence of EE reported by 60.0% of the respondents. In multiple linear regression analysis, the emotional burnout was higher among doctors who were married, female, bearing children, being threatened, displaced internally, non-specialist doctors, working more than 40 hours per week, experienced unsafe medical practice, disagreed with the way manager handle the staff and those who reported that the doctor-patient relationship as not excellent. Conclusion: Our findings suggest that job dissatisfaction, conflict, and violence-related factors were significantly associated with a high level of emotional exhaustion among Iraqi physicians. Keywords: Emotional exhaustion, burnout, workplace, doctors, job satisfaction, conflict, Iraq Background The burnout syndrome has widely discussed since its first time emerged in its three dimensions; emotional exhaustion, depersonalization, and low personal accomplishment [1]. Work- related burnout is becoming increasingly recognized as a serious problem affecting many people working in human services, especially healthcare workers [2]. Work-related burnout found to be directly related to a considerable list of adverse outcomes, including absenteeism from work, increased turnover, and poor job performance [3]. Burnout has shown to have an impact on physicians and their mental and physical health [4,5]. Moreover, Burnout may reflect on clinical performance and the quality of care [6,7]. These features have been regularly reviewed and recognized over the past fifty years [8]. Literature suggests that burnout is a common health problem among doctors in different countries globally [9-12]. However, despite such full recognition in Western societies, the subject of burnout has not received the required attention from the Middle East researchers until the beginning of the 21st century, and to our knowledge, there is a lack of national studies on burnout among Iraqi health workers. This is a particular problem in Iraq, where the health care system has suffered a long-standing catastrophic collapse since 1991 and has overloaded since that time [13]. Furthermore, after the US-led invasion of Iraq in 2003, the health system exposed to deliberate destruction of its infrastructure accompanied by a new exodus of brain drain, including the medical doctors [14]. The high level of violence ___________________________________________________ drsaadalezzi@gmail.com 1Department of Public Health, Faculty of Medicine, Bezmialem Vakif University, Istanbul, Turkey Full list of author information is available at the end of the article http://www.jidhealth.com/ Ali Jadoo et al., Journal of Ideas in Health 2018; 1(2): 42-49 43 in conflict zones such as Iraq produced chronic stress among health personnel, so that continuity in work became almost impossible [15]. Moreover, lack of services and the attempt of the government to spoil the doctor-patient relationship by directing the media to focus mainly on the performance of health care providers made them victims of unfortunate and unjustified incidents of different types of abuse [15,16]. Thus, the combination of lack of security, work, and violence-related and political factors has significantly contributed to raising the level of turnover intention and migration among Iraqi doctors. Consequently, the staying doctors, who are still working in Iraq, were not able to cope with the resultant weakness in the level of health service presented to the patients who already feel dissatisfied and carry a negative impression against this service [17-19]. As a result, the doctors are more likely to pass into a state of an inevitable physical and emotional exhaustion (EE) ending to an exaggerated motivation to leave the job and looking for a better opportunity outside their country [14-19]. This study aimed to predict the main factors related to emotional burnout among Iraqi doctors working in different health care centers during the eruption of armed conflict in 2014. The study focused on Job satisfaction, violence-related variables, work-related variables, and socio-demographic factors to investigate their interrelationships with EE. Methods Study design and subjects This cross-sectional study was conducted among Iraqi medical doctors to test the impact of violence-related and workplace- related variables on the Overall EE. The present study is part of a larger research initiative [14,15], in which we recruited a multistage sampling technique to drew a random sample of 660 physicians from twenty large general hospitals and medical centers covering the main five geographically regions in Iraq (north, west, south, central, and the capital city). Design, sampling, and data collection have been reported in detail previously [14,15]. In the current analysis, responses received from 576 physicians (response rate of 87.3%). At the time of the survey, all Iraqi physicians working at the selected hospitals were included and received a copy of the self-administered questionnaire manually with a contact number and email of the data collector. The exclusion criteria included the chief medical officers (CMO), hospital managers, and their deputies. Outcome variable Emotional burnout assessed by nine items of EE subscale of the validated Maslach Burnout Inventory (MBI) [20-22]. EE answered in terms of frequency on a 7-point Likert scale ranging from 0 (never) to 6 (every day). The overall EE was measured by summing the scores of the nine items (in range of 0 to 54). A higher score indicated greater emotional exhaustion [3] and, accordingly, a higher emotional burnout. The Cronbach’s alpha coefficient of the EE subscale reported in this study was 0.89. Independent variables Job satisfaction measured with the 10-item Warr-Cook-Wall (WCW) job satisfaction (seven-point Likert-type) scale ranging from 1 = "very dissatisfied" to 7 = "very satisfied". The overall job satisfaction was measured by summing the scores of the ten items (in range of 10 to 70). The socio-demographic variables collapsed and coded as follows: age (more or less than 40 years old), gender (male or female), marital status (married or single), presence of children (yes or no), residency (Urban or rural). Variables of conflicts or war-related violence were collapsed and coded as either (1) "Yes" or (0) "No" in response to the following questions: "Because of war violence in Iraq, have you been lost a family member?"; "Have you been threatened?"; "Have you been displaced internally?"; "Do you think that medical practice is safe?" and "The doctor-patient-relationship is excellent?”. Individual work-related variables were categorized as follows: the current professional level (specialist or not); the working hours per week (more or less than 40 hours/week); the number of years spent at their work or the same facility (more or less than ten years); the type of employment (government only or dual in government and private); the training and educational opportunities (yes or no); The way the senior manager handles the staff is effective (agreed or disagreed). Statistical analysis The Statistical Package for Social Sciences (SPSS) version 16.0 used to analyze data in this study. A descriptive analysis of sociodemographic, conflict-related variables, work-related characteristics, and job satisfaction has performed. The nine items of emotional exhaustion subscale summed to obtain the total score (0 to 54). A high degree of emotional burnout determined based on the cut-off point of the emotional exhaustion subscale in the MBI (≥27) [3]. The test of normality of the total score of emotional exhaustion conducted, and the data presented as mean and standard deviation (SD). Student’s 𝑡-test used to compare the mean of emotional burnout score across demographic variables, work-related characteristics, conflict-related variables, and job satisfaction. Categorical data presented as numbers and percentages, and the chi-squared test used for statistical analysis. Multivariate linear regression using the "Backward" technique was employed to obtain factors associated significantly with emotional burnout scores. Variables that were significantly associated with burnout in the bivariate analysis included in the multivariate analysis. The accepted level of significance set below 0.05 (𝑃 < 0.05). Results Descriptive analyses Table 1 shows the descriptive characteristics of the socio- demographic variables. The mean age (±SD) was 40.43 years (±8.59) (in range of 27-56). More than half of respondents (53.8%) were females, married (64.2%), living in urban regions (63.4%), and bearing children (51.2%). There was a significant difference in overall emotional exhaustion. Overall emotional exhaustion was higher among female doctors (95% CI = 0.79- 3.16, p=0.001), married (95% CI = 0.99-3.46, p=<0.000), and those who are bearing children (95% CI = 0.59-2.96, p=0.003).

Most of the conflict or war-related variables showed a significant difference in overall emotional exhaustion. Overall emotional exhaustion was higher among doctors who have been threatened or kidnapped (95% CI = 0.75-3.13, p=0.000), internally displaced (95% CI = 1.50- 3.91, p= <0.000), experienced unsafe medical practice (95% CI = 01.06-3.57, p=<0.000), and those who described the doctors- patients relationship was unwell (95% CI = 1.40-3.99, p=<0.000). Work-related variables on overall emotional exhaustion In table 4, the vast majority (73.3%) of respondents spent more than ten years in the same health facility and were not being specialist yet (60.2%); however, more than half of them (55.7%) have a dual job (government and private) and were satisfied with the available training and educational opportunities. Overall emotional exhaustion was higher among doctors who were not specialist (95% CI = 0.72-3.14, p=0.002), disagreed with the way manager handles the staff (95% CI = 0.72-3.14, p=0.003) and those who are working more than 40 hours per week (95% CI = 0.59-2.97, p=0.003). Predictors of burnout Table 5 shows the results of multiple linear regression analysis to identify the associated variables with emotional burnout. In backward elimination (or backward deletion), the multivariate linear regression analysis (after excluding non-contributing variables) was statistically significant, and overall, explained 24.8% of the variance in the overall emotional exhaustion, F (11, 16.845) = 680.670, P < .0005. The “Internally displaced" and the "doctor-patient relationship” appeared to be the strongest factors predicting the EE (Table 5). Doctors who were internally displaced were more likely to have high EE (B = 0.269, P < .0005). Doctors who considered the doctor-Patient relationship is not excellent were more likely to have high EE (B = 0.267, P < .0005). In general, the emotional burnout was higher among doctors who were married, female, bearing children, being threatened, displaced internally, non-specialist doctors, working more than 40 hours per week, experienced unsafe medical practice, disagreed with the way manager handle the staff and considered the doctor-patient relationship as not excellent.
