Abstract
This study aimed to investigate the perceived work stress and its influencing factors among hospital staff during the novel coronavirus (COVID‐19) pandemic in Taiwan. A web‐based survey was conducted at one medical center and two regional hospitals in southern Taiwan, targeting physicians, nurses, medical examiners, and administrators. The questionnaire included items on the demographic characteristics of hospital staff and a scale to assess stress among healthcare workers caring for patients with a highly infectious disease. A total of 752 valid questionnaires were collected. The hospital staff reported a moderate level of stress and nurses had a highest level of stress compared to staff in the other three occupational categories. The five highest stress scores were observed for the items “rough and cracked hands due to frequent hand washing and disinfectant use,” “inconvenience in using the toilet at work,” “restrictions on eating and drinking at work,” “fear of transmitting the disease to relatives and friends,” and “fear of being infected with COVID‐19.” Discomfort caused by protective equipment was the major stressor for the participants, followed by burden of caring for patients. Among participants who experienced severe stress (n = 129), work stress was higher among those with rather than without minor children. The present findings may serve as a reference for future monitoring of hospital staff's workload, and may aid the provision of support and interventions.

1. INTRODUCTION
The novel coronavirus pneumonia (COVID‐19) caused by a novel coronavirus (SARS‐CoV‐2) infection emerged in 2019. It is similar to the severe acute respiratory syndrome (SARS) that broke out from 2002 to 2003, in that the pathway of transmission is unclear but it can spread with human‐to‐human transmission. Symptoms appear within about 2 to 14 days from virus infection, and the disease progresses rapidly from an asymptomatic state or mild symptoms to severe symptoms or even death. The rate of transmission of COVID‐19 is quite high, with 2 732 709 people diagnosed worldwide by the end of April 2020, covering 184 countries worldwide. The number of deaths continues to increase, with a fatality rate of 6.95%, exceeding the number of SARS cases worldwide. 1 , 2 On April 24, 2003, when the SARS pandemic hit Taiwan, to prevent disease spread, the government ordered the closure of a hospital due to severe cross infection. Healthcare workers rushed out of the blockade line due to insufficient protective equipment and fear of the disease, which resulted in fear of the pandemic among medical staff and the public. As the COVID‐19 pandemic continues to grow, the collective memory of SARS has been revived, and people have vowed not to repeat the same mistake. As a result, hospitals in Taiwan have quickly implemented a containment campaign in response to the currently emerging pandemic by developing emergency response measures. Staffs are required to wear protective equipment, screen patients and visitors entering and leaving the hospital, and set up an outdoor fever screening area in the emergency clinic. Additionally, a scheduling roster has been set up, and all hospital staffs are deployed to fight against the pandemic by providing comprehensive care for patients in negative stress isolation wards or general inpatient wards, and by participating in rotational shifts to implement the quarantine measures at the hospital gate. The pandemic has disrupted the original schedule of hospital staff and has caused changes in their work or lives, resulting in substantial physical and mental stress.
Stress refers to individuals' reactions to different situations. It includes changes in their physiology or psychology in the face of events in the external environment that are evaluated as more than they can bear, such that they affect their physical and mental well‐being. 3 Stress at work is regarded as the process of interaction between the individual and the work environment, which represents an accumulation of negative emotions generated by the work. 4 , 5 These negative reactions lead to the experience of high stress for a long period, which in turn affects physical and mental health. Specifically, it causes multiple adverse symptoms, such as insomnia, headache, fatigue, anxiety, gastrointestinal discomfort, and immunity decline, as well as increased family conflicts, decreased work quality, interpersonal relationship disorders, and other negative effects. 5 , 6 , 7 , 8
Hospital staffs are under high stress during the care process. They have to tackle the effects of misunderstanding by the general public, face worries from family members, experience fear of the unknown disease and of becoming a transmitter of the disease, and experience challenges related to their professional skills of personal infection control. These were major stressors for healthcare workers during SARS, 9 and as such, several of them experienced fear, exhaustion, and stress. 10 Chuang and Lou 11 conducted a survey on 110 physicians and 385 nurses who provided care to patients with SARS in medical centers. They found that infection control anxiety and patient care burden during the containment measures implemented to prevent the spread of highly infectious diseases that are major stressors for healthcare workers. Liu et al 12 reported that, when taking care of patients with underlying infectious diseases, nurses in southern Taiwan hospitals were under great stress due to fear of being infected and passing on the disease to their family.
Extensive research has been conducted to examine the correlation between personal demographics and work stress. Studies have found that marital status, workplace, and educational level have significant effects on work stress. 12 , 13 For example, Wang 14 explored the relationship between work stress and social support among nurses, and found that the older they were and the higher years of work experience they had, the higher was their work stress. This finding suggests that, with the increase of age and accumulation of work experience, nurses are likely to have better attitudes toward and abilities to respond to problems, and accordingly, they would be more likely to be assigned the responsibility to handle unexpected situations at work. 12 , 15 , 16 Unmarried, female, younger medical staff were found to be more prone to high work stress, 17 but work stress was also observed to decrease with the increase in age, years of work experience, and number of children. 16 Another study found that healthcare workers are busy at work, and work stress could result from the conflict of clinical work with family or personal affairs. 18 However, McGrath et al 18 found that marital status, work experience, but educational level had no significant impacts on work stress. 14
The contagion path of COVID‐19 is still unknown. Therefore, since the outbreak of the pandemic, the Taiwanese government has formulated an emergency response plan, and hospitals have adopted several preventive measures. Moreover, hospital staffs have experienced the global impact of this highly communicable disease, whose sudden onset has caused a stress impact that is similar to that of SARS. This leads to the question, “are hospital staff suffering from the same magnitude of stress as before?” Accordingly, the objectives of the present study were (a) to understand the level of stress experienced by hospital staff caring for patients with COVID‐19 and (b) to explore the relationship between the personal demographic characteristics and work stress of hospital staff. The present results could act as a reference for monitoring the work stress of hospital staff, and for accordingly providing support, adjusting manpower, and implementing interventions during the pandemic, to maintain their work stability and quality of life.
2. METHODS
A cross‐sectional survey was conducted from the end of March to the beginning of April 2020, at the peak of the COVID‐19 pandemic in Taiwan. Participants were selected from a 1700‐bed medical center and two 800‐bed regional hospitals in southern Taiwan. The survey was conducted using a web‐based questionnaire and excluded new recruits, outsourced workers, research assistants, and other non‐regular hospital employees. Details of the survey website were provided to the survey participants through the mailboxes of the three hospitals, and the researchers compiled the responses from each hospital for analysis. This study recruited participants from the four main categories of hospital staff, namely physicians, nurses, medical technicians, and administrators. The questionnaire contained the following two sections 11 , 19 : (a) items on participants' demographic characteristics, including age, gender, marital status, number of children, number of minor children, years of work experience, educational level, experience with caring for patients with SARS, experience with caring for patients with COVID‐19, and ward unit for caring for patients with COVID‐19; and (b) the Psychometric Evaluation of Healthcare Workers' Stress Related to Caring for Patients with a Highly Infectious Disease scale developed by Chuang and Lou (2005) 11 for SARS. The scale comprises 4 subscales, namely, “worry and social isolation” with 10 items, “discomfort caused by protective equipment” with 8 items, “difficulties and anxieties related to infection control” with 7 items, and “burden of caring for patients” with 7 items, totaling 32 items. Each item is rated on a 4‐point Likert scale (0: not at all, 1: about the same as usual, 2: slightly more severe than usual, 3: more severe than usual) to assess the degree of stress caused by various stressors. The total score ranges from 0 to 96, with a higher total score indicating a greater degree of stress. A total score of 46 to 96 indicates “severe stress,” that from 33 to 46 indicates “moderate stress,” that from 0 to 32 indicates “low stress,” and 0 indicates “no stress.” The content validity index of the scale was 0.92 in the original study by Chuang and Lou (2005), 11 who tested it on healthcare workers (n = 543) from medical centers in Taiwan. The Cronbach's α values for the four subscales were 0.84 to 0.90 in the original study. In the present study, the Cronbach's α value of the complete scale was 0.94, and that for the four subscales was 0.84 to 0.90.
2.1. Statistical analysis
Data were analyzed using JMP13.0 statistical package. Regarding descriptive statistics, continuous variables related to demographic characteristics and perceived work stress were presented as mean ± SD; categorical variables were presented as counts and percentages. For inferential statistics, the Pearson product moment correlation test was used to analyze the correlations between the study variables. Since severe stress has a significant impact on the physical and mental health of employees 20 and willingness to care for patients. 11 With a projected power of 80%, an alpha of .05, and an effect size of 0.30, the required sample size was 128 participants, as calculated by G Power 3.1.9.4. The 129 employees with scores over 64 points were selected for a t test and one‐way analysis of variance (ANOVA) to identify if stress levels differed based on demographic characteristics, followed by a post hoc Tukey‐Kramer comparison to identify groups with significant differences.
2.2. Ethics
This study was reviewed and approved by the Institutional Review Board (Project Number: KMUHIRB‐EXEMPT[I]‐20 200 008) of the participating hospitals, and a web‐based questionnaire survey was announced in the hospital's bulletin board with the consent of the head of the relevant hospital unit. Data were collected anonymously, and background data were deidentified. The information obtained in this study was subject to the principles of confidentiality and privacy.
3. RESULTS
3.1. Demographic characteristics of hospital employees
The sample comprised 752 hospital staff from one medical center and two regional hospitals in southern Taiwan. As shown in Table 1, participants included 54 physicians, 493 nurses, 89 medical technicians, and 116 administrative staff, with a mean age of 38.7 ± 9.3 years (age range: 23‐65 years). The study subjects were sampled from a web‐based questionnaire and the subject answered the questionnaire voluntarily. The distributions of respondents was similar to the workers in the hospitals (excluding new employees, contractors, and research assistants) from a hospital in southern Taiwan based on staff ratio (Doctor:Nurse:Clinical technologist:administration staff = 1:4:1:1). Majority of the hospital staff were female, married, and with minor children. The years of work experience ranged from 1 to 41 years, with a mean of 11.9 ± 8.9 years. Majority of the participants had received university education, and 10.3% had experience in caring for patients with SARS, with the physicians having the highest percentage of those with such experience, followed by nurses. A total of 19.0% had experience in caring for patients with COVID‐19, among which, most had provided emergency care, followed by care in the negative pressure isolation ward and intensive care unit.

3.2. Relationship between hospital employees' work stress during the COVID‐19 pandemic and their demographic characteristics
Table 2 shows that the mean total score on perceived work stress was 47.7 ± 16.8, representing moderate stress. The main stressor for the hospital staff was discomfort caused by protective equipment, followed by burden of caring for patients. Nurses' mean total score was 50.4 ± 16.9, which was significantly higher than that of medical technicians (44.3 ± 14.4) and administrative staff (40.3 ± 15.1), with the latter two representing moderate stress. The comparison of subscale score among the four types of hospital staff showed that nurses' stress could be attributed more to their fear of social isolation, discomfort due to protective equipment, and burden of patient care. In contrast, medical technicians had a higher degree of stress related to difficulties and anxieties related to infection control.

The mean score for each of the 32 items on work stress was 1.5 ± 0.5 (Table 3), representing mild to moderate stress. The mean scores of each dimension and each item, and score rankings are presented in Table 4. On 19 items, more than 50% of the participants experienced moderate to severe work stress (with mean scores of over 2 points). The five highest stress scores were observed for the items “rough and cracked hands due to frequent hand washing and disinfectant use,” “inconvenience in using the toilet at work,” “restrictions on eating and drinking at work,” “fear of transmitting the disease to relatives and friends,” and “fear of being infected with COVID‐19”. “Hospital staff experienced discomfort caused by the use of protective equipment” and “the burden of caring patients” reported higher scores than other two dimensions of the scale.

Further, for hospital staff with severe stress (n = 129), we performed a t test or one‐way ANOVA to explore whether their stress levels differed based on their demographic characteristics of gender, marital status, years of work experience, educational level, staff type, and experience with caring for patients with SARS. As shown in Table 5, findings indicated a significant difference in stress scores (t = −2.89, P = .005) among staff with and without minor children at home. That is, staff with children aged below 18 years were more stressed than were those without young children. Results of the analysis by scores on the four subscales indicated that staff who experienced stress related to the burden of caring for patients (t = −2.38, P = .019) and fear of social isolation (t = −2.73, P = .007) were more stressed as compared to those without these stressors. The Pearson product‐moment correlation matrix revealed a significant positive correlation (r = .19, P = .031) between having minor children and experiencing work stress.

4. DISCUSSION
This study was the first one conducted in Taiwan to investigate the perceived stress of hospital staff and to identify relevant influencing factors during the COVID‐19 pandemic, using a web‐based structured questionnaire. The results showed that the total stress was moderate and discomfort caused by protective equipment emerged as the major stressor. Nurses generally perceived higher stress as compared to the other types of hospital staff. Difficulties and anxieties related to infection control were major stressors for medical technicians, while administrators were the least stressed among all types of staff. Further, those with minor children experienced a higher degree of work stress.
This study found that discomfort caused by protective equipment was the major stressor for the participants, followed by burden of caring for patients. The overall stress was slight to moderate. This result was consistent with the findings of Yu et al, 21 but it was different from other similar studies conducted during the SARS pandemic. Specifically, those studies found that the main stressor among hospital staff was difficulties and anxieties related to infection control. 11 , 22 , 23 Participants in the present study were more stressed by the discomfort caused by wearing protective equipment for a long period, probably because, to effectively prevent the source of infection from entering the hospital and causing cross infection, the hospital staff were required to wear masks throughout their stay in the hospital. Additionally, they had to set up simple triage stations at the emergency and outpatient departments' entrances, while different types of staff took turns to participate in monitoring individuals entering the hospital. The staff on duty was required to wear basic protective gear, including goggles, protective clothing, surgical masks or N95 masks, and gloves, which made it inconvenient for them to eat and drink at work, as well as to use the toilet. They were required to wash their hands and use disinfectants frequently, and the fear that hands would become rough and cracked made them stressed. The COVID‐19 pandemic has changed the work style and environment of the healthcare system, leading to physical and mental imbalance, and thereby, an increased level of stress among hospital staff. 24
When the SARS pandemic hit Taiwan on April 24, 2003, Medical staff caring for patients with SARS were stressed due to misunderstanding from the general public, fear of becoming carries of the SARS infection, and public panic over the unknown route of infection transmission. 11 , 23 , 25 The painful experience with SARS made people realize that infectious diseases can spread rapidly across national borders and can have far‐reaching impact on the international community and economy. Government in Taiwan has been implementing pandemic prevention and management measures even before the status of the COVID‐19 pandemic was clear. We focused on providing and deploying adequate pandemic prevention equipment in the early stage of the pandemic. Meanwhile, hospitals have also been cooperating with the government in promoting many emergency action plans for pandemic prevention and control, to keep the public informed of changes in the pandemic situation and to provide updated information on prevention and control measures. As a result, there have been very few incidents of people denying or excluding healthcare workers during the COVID‐19 pandemic, unlike what happened during the SARS pandemic. During COVID‐19 control measures, healthcare workers have continually received warm greetings and assistance from people from all walks of life, across the country. Therefore, hospital staff experienced lower levels of difficulties and anxieties related to infection control and stress of social isolation during the COVID‐19 pandemic than during the SARS pandemic.
Stressful events or stressors in the workplace can cause stress reactions, and an employee's personal characteristics and behaviors interact with the practice environment. 26 Strong physical and mental demands lead to an increase in stress levels of hospital staff, which may in turn influence patient care. 27 A survey of 532 regional hospital staff examined the correlation between perceived overwork and musculoskeletal symptoms. Findings revealed that nurses ranked the highest among hospital staff in terms of overwork, followed by administrative staff, medical technicians, and physicians, in order of decreasing overwork. 28 By nature, nursing is a highly stressful occupation. Nurses reported highest stress level in this study. This could be attributed to physical discomfort caused by protective equipment, also, nurses often exposed to patients with frontline infectious diseases for a longer period of time. Compared with other healthcare staff in the hospital, nurses experienced a relatively higher risk of exposure to COVID‐19 patients during the containment period. They also experienced high level of fear of being infected by the virus. Consequently, they experienced a higher level of stress. 11 , 16 Doctors experienced lower level of stress and anxiety, they are also more confident in making clinical decisions. This is due to their ability to access and update their knowledge faster on new SARS related informations. 11 This finding is consistent with the present result that nurses had higher level of stress during the COVID‐19 pandemic compared to other hospital staff. During the pandemic, hospitals could help to reduce frontline nursing staff stress level and increase their confidence at work by setting up standardized work protocol and keeping supply system transparent.
Meanwhile, in addition to oropharyngeal examination, chest X‐ray examination is also considered an important part of the process to identify pneumonia symptoms in patients suspected to have COVID‐19. Medical technicians are required to wear protective equipment when they come in contact with highly‐infectious patients in the outdoor area of the emergency tents. Therefore, as compared to administrative staff, medical technicians experienced higher levels of stress in the area of difficulties and anxieties related to infection control. It is recommended that future education and protection drills on emerging infectious diseases include medical technicians, as this would enhance their infection control awareness and familiarize them with wearing protective equipment. This would in turn help reduce their stress related to unknown infectious diseases.
Previous studies have shown that work stress is related to one's demographic characteristics, 13 , 17 and that child care at home is a common problem for hospital staff, 28 , 29 which is an important factor leading to work‐family conflicts. 30 The present results showed that hospital staff with minor children was more stressed, confirming the viewpoint presented in prior research. However, these findings were different from those reported by Wang et al 14 and Lambert et al, 16 who found that employees with children were less stressed than those without. Perhaps this is due to the parenting style difference between the East and the West world. 31 In the West, parents are more likely to respect each child's individuality and encourage children to explore and develop their own interests. Whereas in the East, parents are more inclined to expect children to follow the rules, society expectations, and achieve high success in career. As the staff included in the present study were around 40 years old, their children would have been closer to adolescence. Adolescents are in the transitional stage of physical development, and in the process of self‐identity development and self‐esteem exploration to gain a sense of independence and control. 32 This stage of development requires more attention and accompaniment from parents. However, during the pandemic prevention period, some staff was worried that they would fail to respond promptly to changes in the condition of COVID‐19 patients under their care, and that they themselves could spread the infection to their family and relatives. Staff working in special or isolation wards either stay in the hospital temporarily for self‐quarantine or return home after 14 days of self‐quarantine following their special ward duty. During their hospital stay, they could be concerned that their minor children would not receive appropriate care in their absence, which could lead to high work stress in such individuals.
In the face of the COVID‐19 pandemic, since the end of January 2020, hospitals started hospital‐wide staff mobilization to contain the pandemic, such as setting up triage stations at the entrances and exits, and medical tents and special wards at the emergency department. These measures changed the existing work pattern of staff and caused unprecedented stress on all types of healthcare workers. As the temperature rises in southern Taiwan, wearing of protective equipment for prolonged periods causes discomfort in staff. Such discomfort can be alleviated by shortening shift durations and installing more mobile air conditioners in emergency and outpatient departments. Since healthcare workers are in a high‐stress occupation, it is recommended that they should be assessed and monitored regularly, and appropriate interventions need to be implemented. It is necessary to provide psychological counselling and stress relief measures for this population. During the pandemic containment, some staff was concerned that they could be carries of the infection after caring for patients with COVID‐19, and that they would bring the source of infection home to their family and relatives. This led to higher work stress on hospital staff with minor children. To cope with this situation, it is recommended to assess the needs of hospital staff with minor children and provide appropriate arrangements for the transportation of employees' children to and from school or offer after‐school programs. This would reduce the burden on frontline healthcare staff who are responsible for pandemic containment. In addition, hospitals may consider recruiting medical technicians as members in the Emerging Infectious Diseases Response Drills in future, as this would familiarize them with various disposal processes. This would enable hospitals to commission these staff, as soon as necessary, for pandemic containment. Such measures would in turn promote the response ability of medical technicians and reduce their stressors.
Due to workforce, financial, and time limitations, this study collected data only from one medical center and two regional hospitals in southern Taiwan. Therefore, we recommend cautions when attempting to generalize the results to the employees in all medical institutions. It is recommended that future studies include other countries, as appropriate, such as some European countries and the United States. Other recommendations for future studies include increasing the sample size, comparing groups with the same number of study subjects, and adopting a longitudinal study design. The stress scale utilized in the present study can be used by hospitals to measure and track changes in the work stress and related influencing factors in hospital staff during pandemics. Additionally, it could serve as a reference instrument to evaluate the effectiveness of the continuous monitoring or intervention measures for improving hospital staff's workload. Together, such findings could be used to provide appropriate support and response measures for hospital staff during a pandemic.
