Depression among health workers caring for patients with COVID-19 in Egypt

Abstract

Background

Health care workers caring for patients with COVID-19 pandemic are prone to extraordinary stressors and psychological problems. The aim of this study was to estimate the prevalence and risk factors of major depressive disorder among health care providers who are caring for patients with COVID-19.

Methods

Two hundred-seventy of health care workers were screened for depressive symptoms by DASS-21 Questionnaire. Only 152 of the participants accepted to be interviewed using SCID-I for diagnosis of major depressive disorder.

Results

According to DASS-21, 28.1% of HCWs had mild-to-moderate depressive symptoms, and 64.8% with severe symptoms. Of 152 who were interviewed using SCID-I, 74.3% were diagnosed with major depression disorder.

Young age, decreased sleep hours, female sex, past history of a psychiatric disease, fear of COVID-19 infection for themselves or their relatives, and fear of death with COVID-19 for themselves or their relatives were significant predictors for major depressive disorder and its severity.

Conclusion

Major depressive disorder is common among HCWs during COVID-19 pandemic. Screening for depression, particularly for young females, and early treatment are recommended.

Background

Lower respiratory tract infections are the communicable diseases with the high mortality rate around the world [1]. In December 2019, a highly infectious acute respiratory syndrome caused by a novel coronavirus (SARS-CoV-2) emerged in Wuhan, China. On March 11th 2020, the World Health Organization (WHO) declared COVID-19 a pandemic [2].

According to previous studies from SARS or Ebola epidemics, the onset of a sudden and immediately life-threatening illness may lead to extraordinary stressors on health care workers (HCWs) [3]. Increased workload, physical exhaustion, insufficient personal equipment, fear of infection, and the need to make ethically difficult decisions may have dramatic effects on their physical and mental well-being. Isolation, loss of social support and fear of transmission of infection to relatives and friends could make HCWs liable to mental health problems, such as fear, anxiety, insomnia and depression [4, 5]. Now in COVID-19 era, health care workers are first-line fighters treating patients with COVID-19 and they are exposed to long and distressing work shifts to meet health requirements which may exceed their individual coping skills [6].

Previous studies have reported the prevalence and factors associated with psychological outcomes in HCWs during past infectious disease outbreaks [7,8,9]. However, the impact of the current COVID-19 pandemic on the psychological well-being of medical staff is yet needed to be studied.

There are only few studies that evaluated depression and its risk factors among HCWs worldwide [10], but they used self-rating scales for assessment of depressive symptoms. The aim of the present research is to estimate the prevalence and potential risk factors contributing to major depressive disorder, which diagnosed by structural interview using SCID-I, among Egyptian health care workers who are caring for COVID-19 patients.

Methods

The data were collected during the period of March–September, 2020. The participants were the HCWs (doctors, nurses, pharmacists, technicians and paramedical workers) who were working in the isolation units for COVID-19 patients, at a university hospital in Egypt. Participants were selected using a convenience sampling technique. Inclusion criteria: age 18–60 years, both sexes and who accepted to participate. The sample size was calculated according the Epi Info 6.0, at 80% power of the study, 95% confidence level [11], with minimum sample size 260. We recruited 300 participants to overcome dropout.

The first step: An electronic Google form survey was sent to the participants via their E-mails (N = 300). It was designed by the authors to collect: 1—socio-demographic data (age, gender, marital status, residence, level of education, occupation and telephone number) and other clinical data; 2—data related to Depression, Anxiety and Stress Scale (DASS-21) for assessment of depressive symptoms. Prior to conducting the survey, the purpose of the study was explained to participants. Only 270 complete the survey and 30 gave incomplete response, so they were excluded.

The second step: All participants who complete the depression subscale of DASS-21 (N = 270) were invited for further evaluation by applying Structured Clinical Interview for DSM-5 disorders (SCID interview) for diagnosis of Major depressive disorder (MDD). The interviews were done in isolation units considering infection control by using the personal protective equipment PPE. Only 152 completed the SCID-I evaluation interview.

Measures

  1. A.

    The Depressive subscale of Depression anxiety stress scale (DASS-21): The Depression Anxiety Stress Scale (DASS-21) is a self-report tool containing 21 items that assess depression, anxiety, and stress. There are subscales with 7 items each (depression, anxiety and stress). Each item is scored on a 4-point Likert scale (0 = did not apply to me at all and 3 = applied to me very much, or most of the time), with a higher score indicating more severe levels of distress. The summation of each scale, then multiplied by two to convert to full scale scores. Each score ranged from 0 to 42. Participants with cutoff scores of ≥ 10 for the depression dimension (≥ 10 as “mild depression”, ≥ 14 as “moderate”, ≥ 21 as “severe”, and ≥ 28 as “extremely severe”), ≥ 8 in anxiety (≥ 8 as “mild anxiety”, ≥ 10 as “moderate”, ≥ 15 as “severe”, and ≥ 20 as “extremely severe”), and ≥ 15 in stress (≥ 15 as “mild anxiety”, ≥ 19 as “moderate”, ≥ 26 as “severe”, and ≥ 34 as “extremely severe”) were considered to have these disorders. The scale has been shown to have good test–retest reliability, internal consistency and convergent validity [12].

  2. B.

    Structured Clinical Interview for DSM-5 disorders, clinician version (SCID-5-CV). For diagnosis of Major depressive disorder [13]

Data analysis was performed using the statistical package for social sciences software (SPSS version 20). The qualitative data were presented in the form of number and percentage. The quantitative data were presented in the form of mean and standard deviation. Groups were compared using independent sample t test for quantitative parameters. For qualitative variables, chi-square was used as a test of significance of differences among groups. Linear and logistic regression was used in the analysis of the predictors for depression. A P-value < 0.05 was considered to indicate statistical significance.

Results

This study included 270 health care workers (HCWs). The studied group age ranged from 18 to 52 years with mean 34.98 ± 6.27 years. 57% of HCWs were female. More than 72% of them had post-graduate education. Most frequent occupations among the participants were physicians and nurses (70.7% and 16.3%, respectively). The most common specialties among physicians were clinical pathology, anesthesia, ICU and pulmonary (10.4%, 10% and 7%, respectively). Most of the HCWs were married (79.6%), from urban area (77.4%) and non-smokers (84.4%). Only 9.6% of the studied HCWs had past history of psychiatric disorders and 12.6% had family history of psychiatric disorders.

Among HCWs, 2.2% reported suicidal thoughts. The working hours ranged from 4 to 14 with mean 9.31 ± 3.1 while sleeping hours ranged from 3 to 10 with mean 6.57 ± 1.27. DASS-21 was answered by 270 of the participants (response rate: 90%). HCWs without depressive symptoms were 7% (N = 19), mild 13.3 (N = 36), moderate 14.8% (N = 40), severe 18.5% (N = 50) and extremely severe depressed HCWs represented 46.3% (N = 125) as shown in Fig. 1.

Table 1 shows the comparison between HCWs with severe-to-extremely severe depression and those with mild-to-moderate depression. There was a statistical significant decrease in mean age and sleep hours among HCWs with severe and extremely severe depression. In addition, there was a statistical significant increase in frequency of severe and extremely severe depression among females, HCWs who had past history of psychiatric disorder, fear of working during COVID-19 pandemic, fear of being infected with COVID-19, fear of infection of a family member with COVID-19, fear of death with COVID-19 and fear of a family member death with COVID-19. The same factors remain significant after linear regression analysis for predictors of depression severity according to DASS-21 score as shown in Table 2.

Depressed HCWs had statistically decreased mean age and decreased sleep hours than non-depressed. Moreover, frequency of depression was statistically increased among females, those who had a past history of psychiatric disorders, presence of fear of being infected with COVID-19, fear of infection of a family member with COVID-19, fear of death with COVID-19 and fear of a family member death with COVID-19 as shown in Table 3. The same factors remain significant after applying binary logistic regression analysis as shown in Table 4.

Discussion

To our knowledge, this is the first research to use the structured clinical interview for DSM (SCID-I) to detect major depression disorder (MDD) among health care workers (HCWs) who were treating patients with COVID-19 in Egypt.

The current study was a cross-sectional survey that enrolled 270 HCWs and revealed a high prevalence of depressive disorder. Overall respondents, 251(93%) had depressive symptoms based on DASS-21. Twenty-eight percent of HCWs had mild-to-moderate depressive symptoms, and 65% with severe or extremely severe depressive symptoms. By applying SCID-I, 74.3% of HCWs were diagnosed with MDD. In a previous study during the acute SARS outbreak, 89% of HCWs who were in high-risk situations reported psychological symptoms [14]. An Egyptian study similarly reported a high prevalence of severe-to-extremely severe depressive symptoms among Egyptian physicians during the COVID-19 pandemic, the majority (63%) suffered from severe or extremely severe depressive symptoms [15]. Also, the prevalence of depressive symptoms among health care providers was (78.1%) in Jordan [16].

Two Egyptian studies and another Saudi one reported that severe depression represents 20.5%, 14%, 5.8%, consequently these results are considered low in comparison to the current one. This can be explained by the using of different measures noting the in this study the authors used the confirmatory diagnostic clinical interview according to the DSM [17,18,19].

Another Turkish study reported that 64.7% of physicians had symptoms of depression [20]. Many studies were performed in China: two of them reported that the prevalence of depressive symptoms among health care providers was 50.4% [21] and 56.0% [22].

The current results reported higher prevalence of depressive symptoms among HCWs than that of other studies, most probably due to the different conditions in which the HCWs are working in Egypt. HCWs did not deal with such a catastrophic and emerging pandemic before. Moreover, they are facing highly infectious disease with uncertain outcome with deficient infection control supplements and shortage of protective equipment that cause overburden and extraordinary stressors over them [22,23,24,25]. In addition, there are other factors that may explain the high prevalence of depression among HCWs generally such as workloads, burnout, insufficient time to take care of their families during the pandemic, social stigma, health anxiety and fear towards COVID-19 infection and reluctance of the society to support them [26,27,28,29,30].

The current study found that young age was associated with higher scores of depression among HCWs. This finding is supported by a recent Jordanian study conducted during the COVID-19 pandemic, which demonstrated that the young age group of HCWs had a significantly high risk to develop depression [16]. A study in Saudi Arabia stated that the age group from 30 to 39 had a slightly high level of depression and anxiety [18]. This is also consistent with recent studies that demonstrate an elevated incidence of psychiatric disorders in younger adults [31, 32]. This could be attributed to the less adaptive manner of responding to stressors that may justify this result [33] and the age-related bio-psychosocial changes [31]. Moreover, young HCWs had to spend a long time in emergency units in close contact with COVID-19 patients to gain clinical experiences, causing a high level of stress and fear of acquiring the infection.

The results showed that fear of being infected with COVID-19 or transmitting the infection to family members, fear of death, or family members’ death with COVID-19, were associated with an increase in the severity of depression among HCWs. In line with these findings, recent studies in China and Nepal reported that medical staffs were fearful about transmitting the virus to their families [21, 23, 28]. A recent study reported that the most concerns regarding the COVID-19-related fears among medical staff in Egypt were the fear of being infected and the fear of transmission of the disease to their families [34]. HCWs may isolate themselves to lower the risk of infecting their family members. Thus the absence of emotional support could attribute the increased psychological distress and affect HCWs mental well-being [35].

The current study found that female HCWs were six times more likely to have depression than male HCWs. Similarly, the results of the Saudi, Jordanian and Egyptian studies indicate that being female increased the risk of depression among health care providers during the COVID-19 pandemic [16, 17, 36, 37]. HCWs with past history of psychiatric illness were seven times more likely to have depression than those without such history according to the current study. In line with this finding, other studies [23, 38] reported that health workers who had a history of medication for mental health problems had a higher risk to exhibit anxiety, depression, and insomnia symptoms compared with those who had no psychiatric history.

In addition, HCWs with decrease in sleep hours were two times more likely to have depression, but depression is associated with decrease in sleep hours and the cross-sectional design of this study cannot answer what started first?

Finally, HCWs who have fear of COVID-19 infection for themselves or relatives were four times more likely to have depression more than HCWs who did not have this fear. Fear of death for HCWs or their relatives double the risk of depression among HCWs. These findings are supported by previous studies [21, 23, 28].

According to these findings, the mental health status of HCWs should be closely monitored by the Ministry of Health to facilitate the appropriate psychological care. They should be provided with appropriate safety measures, their workload should be managed and they should be compensated by the appropriate financial support, to reduce the mental health burden during such pandemic. This study had some limitations which include: first, cross-sectional design does not investigate causality; second, only 56% of the sample size was interviewed using SCID-I, which might limit the strength of using a structural interview instead of self-rating scales. However, this study has some strengths: first, it used structural interview based on SCID-I in addition to self-rating scales; second, it includes many health professions not only physicians.

Conclusions

Three out of four HCWs who were caring for COVID-19 patients had major depression and two-thirds had severe symptoms. Young age, female gender, decreased sleep hours, past history of psychiatric illness, fear of infection or death due to COVID-19 were not only predictors of depression, but also of its severity. Screening for depression among HCWs, particularly for young females, and early treatment are recommended.
