INTRODUCTION: The mental health of the health care professionals is more likely to be affected by the coronavirus disease-19 compared to the general population. Accordingly, the current study aimed to summarize the magnitudes and determinants of the psychological impact of coronavirus among health care professionals. METHODS: The studies from Medline via PubMed, Science Direct, and Google Scholar were searched from 5 September to 19 October 2020. The review was conducted as per PRISMA-2009 (Preferred Reporting Items for Systematic Reviews and Meta-analyses). RESULT: Initially, 6316 articles were searched from three databases (PubMed, Science Direct, and Google Scholar). Finally, 20 articles were filtered to be included in our review. Among different types of psychological impact, stress was reported that lies within the range from 5.2% to 100%, anxiety was reported from 11.1% to 100%, depression was from 10.6% to 58%, and insomnia was from 28.75% to 34%. Several factors were related to the negative psychological state of health care workers due to coronavirus disease-19 like educational level, occupation, gender, age, working environment, work experience, legal status, ethnicity, psychological comorbidity, social support, personal/family exposure, and feeling of health care providers. CONCLUSION: The most common psychological impacts among health care workers were anxiety and stress. Besides different sociodemographic factors that determine the psychological impacts, front-line health care workers and participants having psychological comorbidity have a high risk of negative psychological state impacts as compared to their counterparts. Therefore, special attention should tend to health care workers directly involved in the prevention and management of coronavirus disease-19 and having a different risk of mental health condition.

Coronavirus disease 2019 (COVID-19) is a respiratory infectious disease that is caused by a novel coronavirus 1 and is characterized, especially, by fever, cough, fatigue, dyspnea, and sputum production. 2 COVID-19 became an epidemic affecting all countries of the planet. 3 It has been reported that prime rates of symptoms are related to somatic, emotional, and behavioral disturbances. Such as dissociative disorders, conversion disorder, depression, post-traumatic stress (PTS) disorder, and psychological distress are occurred as consequences of the psychological impact of COVID-19. 4 The study conducted on the previous strain of virus named Severe Acute Respiratory Syndrome (SARS) showed that the onset of a sudden and immediate life-threatening illness had led to extraordinary amounts of pressure on health care workers (HCWs) and might have caused adverse psychological disorders, like anxiety, fear, and stigmatization. 5, 6 In spite of its importance, the quarantine period for the reduction of COVID-19 transmission has a significant impact on the development of various negative psychological outcomes both short and long term. 7 This psychological impact encompasses depression, conversion, dissociative disorders, anxiety, and stress. 8 HCWs had a direct and continuous contact with patients having COVID-19 and their professions were risk factors for various psychological symptoms. Therefore, the burden of psychological impact was high compared to the general population. 9, 10 HCWs who are directly involved within the prevention, diagnosis, treatment and care of patients with COVID-19 could be at high risk of developing anxiety and stress. 11 Front-line health care professionals presented a wide variety of psychological impacts like stress, mania, fear, and insomnia. 12, 13 This psychological pressure can reduce the health care services of the patients. 14 If anxiety is left untreated, it is likely to have long-term health effects on health care workers and prevent them from fulfilling their duties, including the operations aimed at optimal control of the COVID-19 pandemic. 11 The psychological status of health care professionals is impacted by a variety of factors like unknown isolation period, shortage of medical instruments, concerns about the disease, the rapid increase of the COVID-19 cases, overwhelming workload, plenty of information on the burden of the disease released on different social media, lack of treatment, and lack of social support, discrimination and stigma. 9, 12, 14 Similarly, presence of comorbidities, rural residence, female gender, marital status, the title and level of professionalism, having children, and having close contact with the coronavirus disease (COVID-19) infected patients were the most common predictors of the negative psychological impacts among health care professional. 14 Despite the psychological state effects of the coronavirus disease (COVID-19) should be recognized, it has been given less consideration across the world and ignored by simple intervention strategies like social distancing, hand washing, using masks, and quarantine. 1 To make early interventions, comprehensive knowledge of the psychological effects of COVID-19 on health care professionals is indispensable. Besides this, it is paramount to identify different determinants of the psychological impacts of COVID-19 among health care providers. 13 There was scanty of findings on the mental health impacts of COVID-19 in developing countries. As the result, this review examines the determinants of psychological effects in both developed and low resource setting (developing) countries.

This study aims to integrate the previously conducted studies on the prevalence ad determinants of the psychological effects of COVID-19 among health care workers. The review was conducted in line with PRISMA-2009. 15 The two reviewers named F.B. and M.H. were blinded and continuously searched the published studies. The two reviewers have discussed together for disagreement of the relevance of the studies to be included in the review. The articles that were found from PubMed, Science Direct, and Google Scholar and fulfilling the eligibility criteria were included. The review was conducted from 5 September to 19 October 2020. Authors manually checked for a further article to be included within the study. Endnote X5 was used to get rid of any duplicates. The Mesh terms for the entire database were: Determinants OR magnitude AND psychological impact AND health care provide AND COVID-19.

Published findings on coronavirus disease in the English language, which contain the outcomes of interest, and full texts available, were included. The article with the unclear outcome of interest, meta-analysis studies, inaccessible full texts, preprints, and letters (short communication) to editors were excluded.

Articles fulfilling the inclusion criteria were extracted on a data abstraction sheet. The following data were extracted, that is, first name of the investigator and year of study, study setting and design, sample size, age of the participants, sex, occupation, primary outcomes, and their determinants.

National Institute of Health quality assessment tool for observational cohort and cross-sectional studies was used to determine the quality of methodology. As per the tool, all queries were filled with "yes," "no" or "cannot determine" and "not applicable" and "not reported." 16 Accordingly, 10 articles were good, 12,14,17-24 7 were fair, 1, 9, [25] [26] [27] [28] [29] and 3 article was poor. 10, 30, 31 

The articles were searched from PubMed, Science Direct, and Google Scholar. From three databases, 6316 articles were found initially. A total of 2532 articles were removed due to duplication which later 3784 articles were left. After seeing their titles and abstracts, 3747 articles were removed. Therefore, only 37 articles were undergone a full-text review. Finally, we included 20 articles that fulfilled the inclusion criteria to conduct the systematic review ( Figure 1 ).

In our review 19 articles were cross-sectional and one article was prospective. The majority of the study was done by the online administration of the questionnaire and all of the studies were published in 2020. The study was conducted in 16 countries like China, Indonesia, Italy, Ethiopia, Nepal, Spain, USA, Oman, Israel, Peru, UK, and Saudi Arabia, India, Singapore, Malaysia, Vietnam. The review was undertaken from 5 September to 19 October 2020. The majority of the respondents were female in 17 of the articles, whereas male was predominant in the study of Ethiopia and the United States. 1, 17, 22 In relation to their age, the majority of the participants fall in the adulthood age category. In terms of their occupations, the study conducted in Italy 17 and Spain 30 showed that most of the participants were physicians. However, Nurses were dominant in Indonesia, 10 Oman, 31 Nepal, 20 Ethiopia, India, Singapore, Malaysia, and Vietnam Indonesia. 1, 14, 23, 24 In the United Kingdom and the United States, all of the participants were physicians. 19, 28 Variable reports were obtained in China 9,18,12,25,29 ( Table 1) .

The randomization and hiding of study participants were unknown in 10 articles and sufficient in the remaining 10. 1, 12, 14, 18, 23, 25, 26, 29, 30 Blinding of health care workers was unknown in 12 of the articles and sufficient in 8. 1, 9, 12, 14, [23] [24] [25] 29 In 18 studies, there was sufficient blinding of outcome measures, but unknown in 2 articles. 10, 22 Incomplete outcome data were obtained in Saudi Arabia. 22 There were systematic differences in the loss of participants from the study and how they are accounted in the results and methods of outcomes assessment affects group comparison. Other types of bias like Selective outcome reporting were not found in the study.

Among various types of mental health impact, stress was most common in four articles conducted in China ranges from 40.2% to 71.5%, 9, 12 Italy 36.7%, 17 and Oman 56.4%. 31 The study of Spain, 30 China, 25 and Israel 26 reports only on stress. However, anxiety was predominant in five articles conducted in Indonesia 33.4%, 10 China 46.04%, 18 Nepal 41.9%, 20 Saudi Arabia 68.2%, 22 Singapore, and India. 24 Anxiety was solely studied in China 27 and Ethiopia. 14 The magnitude of the depression was high in the two countries: the United States, 27.2%, 19 and China 58%. 29 PTS was highly reported in the study of China, Italy, India, Singapore, Malaysia, Vietnam, and Indonesia which ranges from 7.4% to 47.3%, 9, 17, 23 and insomnia has occurred in the study of China and Nepal 12, 18, 20 (Table 2) . 30 • Stress = 100%

• Work environment • Psychotherapy use • Personal exposure • Family exposure Kannampallil et al. 19 • Depression = 27.2%

• Stress = 24.7%

• Anxiety = 18.6%

• Gender • Marital status • Trainees exposed to COVID-19 testing Badahdah et al. 31 • 

In the current study, multiple predictors of the psychological impact of COVID-19 were obtained. The study done in China, 9, 10 Italy, 17 and Ethiopia 1 revealed that being a nurse was the common factor that leads to high negative mental health outcomes. However, the study done in Ethiopia revealed that being a pharmacist was a predisposing factor for the psychological impacts of COVID-19. 1 Lack of treatment for COVID-19 was a risk factor for negative mental impacts of COVID-19 among health care professionals in China. 25 The attitudes of the health care providers were the determinants of the psychological impacts of COVID-19 in China and Ethiopia. 14, 25 Among sociodemographic factors, gender was a determinant of the psychological impacts, consistent with the study of China, Italy, the United States, Oman, Singapore, and India. 10, 17, 19, 24, 29, 31 In our study being a female was predictor of the various types of psychological features. Age is a determinants in 7 articles conducted in China, Italy, Oman, Nepal, Peru, Singapore and India. 10, 17, 20, 21, 24, 25, 31 The majority of the studies found that the mental health impacts were higher in older populations. Marital status was predictors in the study of Indonesia and the United States. 10, 19 Front-line health care workers had a high risk of psychological impacts as compared to others in two studies of China. 12, 18 Participants having psychological comorbidity have a high risk of negative mental health impacts, according to the study of Italy, China, India, Singapore, Malaysia, Vietnam, and Indonesia 17,23,24,27 (Table2).

Globally, the mental health impact and discriminations due to coronavirus disease-19 infections are increasing. 32 These discriminations have resulted in different psychological effects such as anxiety and stress. 3, 7 This psychological impact was exacerbated by different situations like separation of partners, unknown disease characteristics, lack of supplies for preventive measures, lack of money, a low attitude of the peoples, and false information from media. 8 Health care professionals directly involved in coronavirus disease-19 management were more likely affected by different psychological symptoms of depression, stress, anxiety, anger, fear, and lack of sleep. 33 In the current study, the three commonly occurred psychological features were common mental disorder which includes anxiety, stress, and depression. However, three articles studied in China, and Nepal found insomnia among health care workers, 12, 18, 20 which is consistent with the finding of Philip and Cherian 13 Similar results were observed in Italy and, China. 17, 18 However, insomnia was the most commonly reported problem, and depression and PTSD were the least commonly occurred psychiatric features according to the study of de Pablo et al. 34 The introduction of online-based psychotherapy intervention like cognitive behavioral therapy (CBT) and mindfulness-based cognitive therapy (MBCT) can enhance the mental wellbeing of the HCWs. 35 There was strong support for the effectiveness of Internet cognitive behavioral therapy in treating insomnia. 36 Anxiety was only reported in the finding of a study from China 27 and Ethiopia. 14 This is in line with the systematic review conducted previously by Bekele et al. 37 The variable reports of psychological impacts are because of different sociodemographic factors and psychological comorbidities of included HCW across the different countries.

In the current review, different types of risk factors have been identified which might be correlated with the psychological impacts of COVID-19 among health care workers have been identified which includes sociodemographic factors (age, gender, ethnicity, marital status, occupation). 9, 10, 12, 17, [19] [20] [21] 25, 28, 29, 31 This is similar to the study of Germany, 3 Mexico, 38 the United Kingdom, 28 and a finding of China, 12 Luo et al. 39 and different from the study of China. 27 In the elderly populations, the magnitudes of anxiety, depression, and stress were found to be high as compared to younger ages, 10, 17, 20, 21, 25, 31 which is consistent with the study of Asia and Europe 40 and inconsistent with the study of Mexico in which the psychological distress was prevalent in younger ages. 38 This might be due to the impact of the comorbidities, immune system capacity, and poor coping strategies elders experience with aging. Gender was another factor shown to have an association with common psychological conditions among HCW. Accordingly, female health care workers have more risks of anxiety, insomnia, and stress than men, 10, 12, 17, 19, 28, 29, 31 and this is similar to the study done in Addis Ababa 41 and the reports of Salari et al. 40 The working environment was another determinant of psychological impacts. 10, 12, 17, 21, 27, 30, 31 Similar reports were obtained in Saudi Arabia and Indonesia. 10, 42 Two of the studies conducted in China revealed that health care professionals working in the front-line were more likely to be affected by different psychological effects like stress, anxiety, depression, and insomnia. 12, 18 This is consistent with the study of Saudi Arabia and China. 42, 43 This might be related to increased risk of contracting the infection and care demands leading to reduced psychological stability and will increase the risks of developing emotional disturbance.

Psychological comorbidity was one of the risk factors for negative impacts of mental health in Italy, 17 which is similar to the study of Luo et al. 39 It is noteworthy that this population especially has a higher chance of severe mental disorder due to the fear of new pandemic disease. As limitations, the study included in this systematic review mainly used selfreported questionnaires to measure psychiatric symptoms and did not make a clinical diagnosis. Furthermore, all of the articles were cross-sectional, making it difficult to determine temporal relationships other than a single study. The limited number of studies published, heterogeneity of the articles, and incomplete outcomes of the psychological impacts were other limitations. Besides this, only published articles in reputable international journals were included and most articles failed to report proper randomization techniques.

In our review, different psychological disorders like depression, PTSD, anxiety, insomnia, and stress were reported. Several demographic factors were associated with the psychological impacts of coronavirus disease-19, such as educational level, occupation, marital status, ethnicity, gender, and age. Besides, front-line health care workers and participants having psychological comorbidity have a high risk of negative mental health impacts as compared to their counterparts. Therefore, the current review will update the health care workers with the different psychological impacts of COVID-19 during their clinical practice. Besides this, special attention should be given to health care workers directly involved in the prevention and management of coronavirus disease-19 and having the different risks of mental illness.
