BACKGROUND: Internists who have an important role in the global response to the COVID‐19 pandemic are under both physical and psychological pressures. AIMS: To assess the anxiety among physicians working in the internal medicine department of a tertiary care hospital who are on the frontline of the COVID‐19 pandemic. METHODS: This single‐centre, non‐intervention, cross‐sectional descriptive study was conducted using an online survey questionnaire from 1 April to 14 April 2020. Physicians of the Department of Internal Medicine were invited to participate with a self‐administered questionnaire. The degree of symptoms of anxiety was assessed by the Turkish versions of the 7‐item Generalised Anxiety Disorder scale and Beck Anxiety Inventory, respectively. RESULTS: A total of 113 participants consented for the study and completed the questionnaire. The median age was 29 (IQR = 5) years and 53.1% were male. A total of 72 internists (63.7%) worked as ‘frontline’ healthcare workers directly engaged in diagnosing, treating or caring for patients with or suspected to have COVID‐19. Female gender was significantly associated with high scores and levels in all scales compared to the male gender (P < 0.005). Having family members over 65 years old and with chronic diseases were significantly associated with high anxiety scores and levels (P < 0.005). CONCLUSIONS: In this survey of internists in a university hospital equipped with clinics, wards and intensive care unit for patients with COVID‐19, female gender and having family members over 65 years old and with chronic diseases were associated with increased anxiety levels.

The World Health Organization (WHO) China Country Office was informed about accumulated pneumonia cases of unknown aetiology in Wuhan City, Hubei Province of China, on 31 December 2019. 1 The Chinese authorities isolated and identified a new type of coronavirus, named 2019 novel coronavirus (2019-nCoV, then SARS-CoV-2). The disease spread rapidly to many countries all over the world and WHO declared coronavirus disease 2019 (COVID-19) as a pandemic. 2 Since its identification in December 2019, COVID-19 has infected over 4 million people globally. 3 Healthcare workers (HCW) have an important role in the global response against the COVID-19 pandemic. Since the start of the COVID-19 outbreak, concerns such as fear of being infected with coronavirus, anxiety of infecting loved ones, difficulty in access to personal protective equipment, delay in test results, lack of specific drugs, feelings of being inadequately supported and making quick decisions with limited information have increased. These concerns can increase the fragility of healthcare professionals and the healthcare delivery may worsen when their ability to stay calm and reassure the public is most needed. Maintaining an adequate healthcare workforce in this pandemic requires an adequate number of physicians, nurses, pharmacists and physical therapists, with abilities to care for a high volume of patients.

During the outbreak of severe acute respiratory syndrome (SARS) in 2003, significant emotional distress was present in 18-57% of HCW and was associated with quarantine, fear of contagion, concern for family, job stress, interpersonal isolation, perceived stigma and attachment insecurity. 4 In 2009 A/H1N1 influenza pandemic, 56.7% of HCW presented frequent concerns regarding their health and their families' health, high levels of psychological distress, worries about their functional ability and fears of stigmatisation during previous disease outbreaks. 5 Now, similar concerns about the emotional distress of HCW treating patients with COVID-19 are arising. Understanding the occupational and psychological effects of the COVID-19 outbreak is important because it comprises the well-being of physicians.

As of 11 March, after the detection of the first case in Turkey, certain hospitals were determined to serve as COVID-19 pandemic hospitals, as was our hospital. The disaster and the pandemic plans of the hospital, which is a Joint Commission Accredited 1200-bed, tertiary care, university hospital in the capital city of Turkey, have been activated. All policlinics were closed except the emergency department. All elective surgeries were cancelled. The hospital was organised entirely to take care of COVID-19 patients and emergent and urgent cases. Dedicated Internal Medicine Wards and Intensive Care Units (ICU) were reserved for follow up of COVID-19 patients. A COVID-19 initial evaluation outpatient clinic was established. Internal medicine department staff have been assigned to work in the COVID wards and outpatient clinic in alliance with the Departments of Chest Diseases, Cardiology and Infectious Diseases in accordance with the pandemic preparedness plan.

The objective of this study is to assess the psychological and occupational impact of COVID-19 pandemic on physicians working in the internal medicine department and to identify associated factors that increase vulnerability.

This single-centre, non-interventional, cross-sectional descriptive study was conducted in a tertiary care university hospital, using an online survey questionnaire from 1 April to 14 April 2020 when COVID-19 cases have recently been identified and trending towards the peak in Turkey. The first COVID-19 case was admitted to our hospital on 20 March 2020, and there were 147 confirmed cases until April 14. The personal protective equipment was distributed to the staff with regard to the guidance and the principles set by the Infection Control Unit and there were no shortages. The working hours of the doctors in the COVID-19 wards were amended to have 12-h working shifts every other day.

Physicians (academic staff and residents) of the Department of Internal Medicine were invited to participate with a self-administered questionnaire on a digital platform. Electronic informed consent of all participants was obtained. The study protocol was approved by the Institutional Ethics Board (Approval number: GO 20/353, date: 31.03.2020), and carried out in accordance with the ethical standards laid down in the 1964 Declaration of Helsinki as revised in 2000.

The questionnaire consisted of three parts. The first part included questions about socio-demographic characteristics including age, sex (male, female), marriage status (married, single, divorced), family members status (having children, having family members over 65 years of age), working position (as a 'resident' or as an 'academic staff' that includes specialist, fellow, associate professor and professor), working department, working experience ('year of residency' for the residents and 'duration of working experience as a physician' for the academic staff), working area ('frontline' such as COVID-19 wards, ICU, outpatient clinics or 'non-COVID-19 areas' such as other wards and outpatient clinics) and medical history of the participants and their families.

In the second part, they were asked three questions which aimed to assess knowledge and fears about COVID-19 (Table 2 ).

In the third part, the degree of symptoms of anxiety was assessed by the 7-item Generalised Anxiety Disorder scale (GAD-7) and Beck Anxiety Inventory (BAI). All the scales used have previously been adapted to Turkish and were tested for their validity and reliability. 6, 7 Participants who had scores greater than the cut-off threshold were characterised as having severe symptoms. GAD-7 is one of the most frequently used and validated diagnostic self-report scales for screening, diagnosis and severity assessment of anxiety disorder. The total score of GAD-7 ranges from 0 to 21, with increasing scores indicating more severe functional impairments as a result of anxiety. The total scores of these measurement tools are interpreted as follows: GAD-7 level indicates minimal (score 0-4), mild (score 5-9), moderate (score [10] [11] [12] [13] [14] or severe anxiety (score [15] [16] [17] [18] [19] [20] [21] . A score of 10 or greater in the original GAD-7 represents a reasonable cut-off point for identifying cases of general anxiety disorder. 8 We used '8' as the cut-off score for detecting symptoms of anxiety based on the Turkish version of GAD-7 scale. 6 The BAI is used to determine the frequency of anxiety signs. There are 21 categories of signs, each consisting of four options, and each item is scored on a scale of 0-3; 0 -Not at all; 1 -Mildly (It did not bother me much); 2 -Moderately (It was very unpleasant, but I could stand it) and 3 -Severely (I could barely stand it). The total score has a minimum of 0 and a maximum of 63. The standardised score levels are as follows: 0-7, minimal anxiety level; 8-15, mild anxiety level; 16-25, moderate anxiety level; 26-63, severe anxiety level. 7 Consequently, we used five main parameters in the assessment of the anxiety: anxiety levels according to scales ('GAD-7 level', 'BAI level'), total scores ('GAD-7 score', 'BAI score') and the cut-off score 8 for detecting symptoms of anxiety based on the Turkish version of GAD-7 scale ('GAD-7 Cut-off 8') ( Tables 3, 4 ).

All statistical analyses were performed with SPSS statistical software package (SPSS, IBM, Armonk, NY, USA) version 25. In descriptive statistics, number and percentage were used for categorical variables. For continuous variables with normal distribution, mean and standard deviation (SD) were used; and for continuous variables that do not show normal distribution, interquartile range (IQR) was preferred. Pearson Chi-squared test or Fisher exact test were used in the evaluation of categorical variables. The suitability of variables to normal distribution was examined using visual and analytical methods. Nonnormally distributed numerical data were analysed with Mann-Whitney U-test or Kruskal-Wallis test. For all comparisons, P-values less than 0.05 were considered as statistically significant.

A total of 113 participants consented for the study and completed the questionnaire. Median age was 29 (IQR = 5) years and 53.1% were male (Table 1) . 

Internal Medicine Journal (2020) 1-9

Seventy-seven (68.1%) of the participants were residents and the mean residency year was 2.3 (±1.1) years. Thirty-six (31.9%) of the participants were academic staff whose median working experience was 7 (IQR = 18) years. Fifty-two (67.5%) residents were unmarried and all but three had no children, whereas 31 (86.1%) academic staff were married and 24 of them (66.6%) had children. Among all participants, 23 (20.4%) had chronic diseases and 41 (36.3%) admitted that they had family members older than 65 years and 64 (56.6%) had family members suffering from chronic diseases.

A total of 72 internists (63.7%) worked as 'frontline' HCW directly engaged in diagnosing, treating or caring for patients with or suspected to have COVID-19. Remaining 41 physicians (36.3%) worked in areas that were deemed to be 'non-COVID-19 areas' such as general internal medicine, endocrinology, nephrology, rheumatology, gastroenterology, medical oncology, haematology, geriatric medicine, infectious disease, cardiology and pulmonology clinics. Table 2 lists the answers of the participants to questions with regard to the knowledge and fear towards COVID-19: 45 (39.8%) participants answered that they have enough knowledge about COVID-19, 39 (34.5%) participants stated that they can manage the follow up and treatment process correctly when they encounter COVID-19 patients, while 56 (49.6%) participants answered that they are anxious about the possibility of following COVID-19 patients. There was no statistically significant difference between residents and academic staff with regard to the answer categories (Table 2) .

The median (IQR) scores on the GAD-7 and the BAI for all internists were 4 5 and 6 (9.5) respectively. For the GAD-7 anxiety subscales, half of the internists, 57 (50.4%), had scores within the minimal level, while 35 (31%) internists were considered to suffer from mild anxiety (score: 5-9); 12 (10.6%) were considered to suffer from moderate anxiety (score: 10-14); and 9 (8%) were considered to suffer from severe anxiety (score: [15] [16] [17] [18] [19] [20] [21] . Based on the Turkish version of GAD-7 scale most of the internists, 88 (77.9%), have normal scores, under the 'GAD-7 cut-off score 8', and did not require further assessment, whereas 25 (22.1%) internists scored ≥8 indicating the need for further assessment and/or referral to a mental health professional. BAI levels were also compatible with GAD-7 levels and the majority of internists were not found to have high anxiety scores (Table 3) .

Female gender was significantly associated with high scores and levels in all five scales compared to male gender (GAD-7 level; P = 0.001, GAD-7 cut-off 8; P = 0.009, GAD-7 score; P < 0.001, BAI level; P = 0.034, BAI score; P = 0.005). Additionally, having family members over 65 years of age (GAD-7 level; P = 0.013, GAD-7 cut-off 8; P = 0.037, GAD-7 score; P = 0.009, BAI level; P = 0.067, BAI score; P = 0.002) and with chronic diseases (GAD-7 level; P = 0.041, GAD-7 cut-off 8; P = 0.047, GAD-7 score; P = 0.005, BAI level; P = 0.038, BAI score; P = 0.001) were significantly associated with high anxiety scores and levels in all 5 scales. Other sociodemographic variables including age, marriage status, children status were not associated with anxiety scores and levels (Table 3) .

There was no statistically significant difference between residents and academic staff in terms of all five anxiety scores and levels. Working area was an insignificant factor in terms of anxiety, and working in either COVID-19 ICU or COVID-19 ward or COVID-19 outpatient clinic was not associated with higher anxiety scores and levels (Table 4) .

COVID-19 outbreak caused considerable concern all around the world because of its speed of transmission and high mortality rate. A general public survey during the initial phase of the COVID-19 outbreak in China showed that 28.8% of the participants reported moderate-to-severe anxiety and 53.8% of respondents rated the psychological impact of the outbreak as moderate or severe. 9 Increasing anxiety and panic in all communities has also seriously affected HCW, who are under high-stress conditions due to increased risk of exposure to the virus, carrying the possibility of transmitting the virus to friends and family members, the lack of sufficient knowledge, resources, treatment or vaccine and the need to make new and quick decisions in critically ill patients. A cross-sectional study aiming to assess the mental health of Chinese public during COVID-19 outbreak identified that HCW were at high risk of mental illness. 10 This study was carried out in the early stages of the pandemic when the number of COVID-19 cases were increasing rapidly towards the peak in Turkey. As the pandemic plan was activated, the command chain of the disaster plan was in place and all preparations were made quickly in our hospital. Staff was well provided with personal protective equipment in accordance to the guidance by the Infection Control Unit with best available evidence. Although routine work patterns of all staff have been disrupted, in order to limit viral exposure, working times of the HCW in COVID-19 areas have been reorganised in 12-h shifts every other day. No matter how resilient the healthcare system in the hospital is, the fear of an approaching disaster and the uncertainty ahead are strong factors for anxiety.

The overall median (IQR) scores on the GAD-7 and the BAI for all internists were 4 5 and 6 (9.5) respectively, reflecting minimal anxiety levels. More than half of the participants had minimal anxiety score levels (GAD-7; 50.4% and BAI; 56.6%). The prevalence of severe anxiety levels was 8% for GAD-7 and 9.7% for BAI respectively. In previous studies during the 2003 SARS outbreak, 2009 influenza A/H1N1 outbreak and 2014 Middle East Respiratory Syndrome outbreak, a significant proportion of HCW were reported to experience anxiety symptoms and to have high psychological distress. 5, 11, 12 Comparing different groups, doctors reported fewer worries than other HCW, while the anxiety level was significantly higher in nurses than in doctors. [13] [14] [15] [16] Similarly, during the A/H1N1 influenza pandemic, greater proportion of nurses and auxiliary staff also had increased concerns and higher degree of worry compared to doctors. 5 In our study, the proportion of participants who developed anxiety and distress symptoms and the level of anxiety were lower than those reported in previous disease outbreaks, which could be attributed to the selection of participants only among physicians.

It has been shown that the lifetime prevalence of GAD is higher in women (6.6%) than in men (3.6%). 17 Similarly, anxiety levels of female physicians were reported to be higher than male physicians. 18, 19 In a crosssectional survey, female physicians had higher anxiety levels than males and have also been reported to be exposed to certain stress factors related to discrimination, lack of role models and support, role stress and overload. 20 Biological factors, such as the variation in ovarian hormone levels, may contribute to the increased prevalence of depression and anxiety in women. 21 In our study, female physicians reported more severe symptoms of anxiety in all measurements, consistent with the results of previous studies. [22] [23] [24] [25] Risk factors related to social life, differences in physical strength and personality traits might influence the risk of anxiety in women. Therefore, female doctors might need a closer follow up and higher level of support to maintain good mental health, while treating patients with COVID-19.

Studies during the SARS, influenza A/H1N1 and recent COVID-19 outbreaks showed that working in high-risk work environment was an independent risk factor for worse mental health outcomes. [26] [27] [28] [29] On the other hand, there are studies showing that exposure to high-intensity and high-risk work environments is not the primary risk factor for psychological distress. 4 In the present study, working in a frontline COVID-19 area was not associated with higher anxiety scores and levels. Additionally, there was no significant difference between working either in COVID-19 ICU or COVID-19 ward or COVID-19 outpatient clinics.

Increasing age and chronic diseases have been reported to be risk factors for worse outcomes with regard to COVID-19. In this study, having family members over 65 years of age and with chronic medical conditions were significantly associated with high anxiety scores and levels in all measurements. Previous studies have also indicated that increased concerns about their family's health were important emotional stressors highly prevalent among HCW. 9, 30, 31 On the other hand, we could not demonstrate an association between having children and higher levels of anxiety, which might be due to the facts that children and adolescents are less likely to experience severe COVID-19. However, some studies indicated an association between high levels of concern about a child younger than 16 years getting COVID-19 and higher anxiety scores. 9, 32, 33 This study has several limitations. First, it was limited in scope. All participants were internists in a Joint Commission International accredited, large, urban teaching hospital, which may limit the generalisation of our findings to all HCW and the community. Second, the duration of the study was the more stressful 2 weeks of the pandemic in our hospital, when the patient numbers increased sharply. This situation could have aggravated the mental health symptoms of HCW. We included only medical doctors and even only internists. The level of knowledge and perception may differ between internists and other medical specialists in terms of critical and difficult patient care, emergency patient approach experiences, and so on. We conducted a rapid survey due to the time limitation of the pandemic and a self-designed questionnaire was used. Gathering information regarding psychological distress by self-report is a further limitation.

It is important to understand the professional and psychological effects of practice during this COVID-19 outbreak, since the well-being of a large number of healthcare professionals is of concern. Female doctors and physicians who have elderly family members and family members with chronic medical conditions showed more severe symptoms of anxiety. We believe that the results of this study are valuable as it points out a vulnerable point in the healthcare system during the COVID-19 outbreak, that is the mental health. These findings need to be confirmed and investigated with follow-up studies that would be useful for the assessment of the progression of psychological manifestations.
