Depression, anxiety, stress and other mental health conditions of personnel undergoing hospital isolation during the COVID-19 pandemic and influencing factors

Objective: To understand the depression, anxiety, stress and other mental health conditions of personnel undergoing hospital isolation during the COVID-19 pandemic and the influencing factors. Methods: This was retrospective study. A total of 120 personnel undergoing Baoding No.1 Hospital isolation who completed the questionnaires were included from June 10, 2021 to February 07, 2022. The Patient Health Questionnaire-9(PHQ-9), the Generalized Anxiety Scale (GAD7) and psychological stress measurement table (PSTR) were used for psychological problem screening for personnel undergoing hospital isolation. Results: The incidence of depression was the lowest, while that of stress was the highest. The difference in the incidence of depression, anxiety and stress among personnel undergoing hospital isolation with different gender, age, income statuses, marital statuses and attitude towards isolation was statistically significant (p< 0.05), while the difference in the incidence of these problems among personnel with different degree of education was not statistically significant(p> 0.05). Multivariate Logistic regression analysis showed that age, gender, marital status, economic status and attitude towards isolation are factors associated with stress. Economic status and attitude towards isolation are factors associated with depression. A high economic level is a protective factor against depression, while a negative attitude is a risk factor for depression. Conclusion: During the COVID-19 pandemic, anxiety, depression and stress increased to different extents in personnel undergoing hospital isolation, especially in females with poor economic conditions and poor attitudes towards isolation. Therefore, necessary psychological counseling and social support should be provided to these people.


INTRODUCTION
COVID-19 is an emerging infectious disease with such epidemiologic features as a complex transmission route, strong infectivity and general susceptibility caused by a novel coronavirus of β coronavirus genus. 1 The World Health Organization (WHO) classified the COVID-19 pandemic as a "global pandemic" in 2020. 2 It has diversified transmission routes, high incidence and strong infectivity.Its clinical manifestations are fever, respiratory symptoms, imaging features of pneumonia, normal or decreased white blood cell count or reduced lymphocyte count at the early stage of the disease. 3The early mortality is high.Although the mortality gradually decreases over time, it still has certain mortality for infected people. 4At present, an isolation regime, including hospital isolation and centralized isolation for medical observation, is implemented on close contacts in many countries and regions.
During the COVID-19 pandemic, most patients in isolation wards show irritability, panic, anger and other emotions, which impairs the body's immune system and may cause serious impairment of the entire psychological system.Moreover, personnel undergoing hospital isolation are also suffering the consequences of negative emotions, such as depression, anxiety and stress. 5Serious psychological problems may also affect physical health.Therefore, it is necessary to explore the negative emotions of personnel undergoing hospital isolation during COVID-19 and provide early intervention.This study was intended to survey the distribution characteristics of the depression, anxiety and stress of personnel undergoing hospital isolation during the COVID-19 pandemic to provide a basis for regulating the physical and mental health of isolated personnel and relevant psychological intervention.

METHODS
This was retrospective study.A total of 120 personnel undergoing Baoding No. scoring.The answer and score for each item are as follows: not at all (0), several days (1), more than one week (2) and almost every day (3).The total score is 27 points.The higher the score, the greater the likelihood of depression.Based on the score, the degree of depression can be divided into mild depression (6-9 points), moderate depression (10-14 points), severe depression (15-21 points), and extremely severe depression (22-27 points). 6he Generalized Anxiety Scale (GAD-7): It is composed of seven items and also adopts Likert4 grade scoring, specifically as follows: not at all (0), occasionally (1 point), frequently (2 points), almost every day (3  points).According to the score, the degree of anxiety is divided into mild anxiety (5~9 points), moderate anxiety (10~14 points) and severe anxiety (above 15 points). 7The PSTR: It includes 50 items, each of which is scored 0~4.The higher the score, the greater the stress.A score of 43-65 points, lower than 43 points and higher than 65 points indicates moderate stress, small stress and great stress, respectively. 8All the questionnaires were given to the participants for investigation, and then collected in about five minutes.

Statistical analysis:
The software SPSS 20.0 was used for the statistical analysis of all data.The measurement data were expressed as ( ±S).The sample size was estimated by 95% confidence interval.Independent samples t-test and ANOVA were used for intergroup data analysis, while Logistic regression analysis was used for the analysis of relevant risk factors.P<0.05 was considered statistically significant.

RESULTS
The incidence of depression, anxiety and stress in personnel undergoing hospital isolation was 21.6%, 31.4% and 33.8%, respectively.The incidence of depression was the lowest, while that of stress was the highest, ( With age, gender, marital status, economic status and attitude towards isolation as independent variables, multivariate logistic regression analysis was performed after assignment, α input =0.05, α output =0.10, the results showed that: age (p= 0.000), gender (p= 0.000), marital status (p= 0.001), economic status (p= 0.000), attitude towards isolation (p= 0.000) are factors associated with stress.High economic level is a protective factor against stress, while gender, female, married and divorced, and negative attitude are risk factors for stress, (Table-IV).
With age, gender, marital status, economic status and attitude towards isolation as independent variables, multivariate logistic regression analysis was performed after assignment, α input = 0. 05, α output = 0.10, the results showed that: gender (p= 0.000), economic status (p= 0.000), attitude towards isolation (p= 0.000) are factors associated with anxiety.High economic level is a protective factor against anxiety, while female and negative attitudes are risk factors for anxiety, (Table -

DISCUSSION
According to the results of this study, the incidence of depression, anxiety and stress in personnel undergoing hospital isolation was 21.6%, 31.4% and 33.8%, respectively.Age, gender, marital status, economic status and attitude toward isolation are factors associated with stress.A high economic level is a protective factor against stress, while gender, female, married and divorced, and negative attitude are risk factors for stress.Gender, economic status and attitude towards isolation are factors associated with anxiety.Economic status and attitude towards isolation are factors associated with depression.Isolated medical observation is a measure to isolate people who may have been exposed to infection sources and restrict their range of activity, so as to reduce the risk of infecting others and avoid the spread of infectious diseases in the population.Studies have shown that 9   public health emergencies, the isolated personnel often show different degrees of anxiety, depression, insomnia and other psychological symptoms and that some psychological problems are persistent and complex. 10herefore, the influence of negative emotions of isolated personnel should be reduced as far as possible while effectively coping with the COVID-19 epidemic by means of isolation.Anxiety, depression and stress are people's subjective emotional experiences.Anxiety is mainly manifested as nervousness, worry, restlessness, and autonomic symptoms without a clear object. 11Depression is clinically manifested as significant and persistent low mood, which does not fit with the situation.Anxiety, depression and somatic symptoms may exist separately or in combination, or occur with physical disease. 12Both anxiety and depression affect patients' social role and quality of life(QOL), resulting in physical, psychological, cognitive and behavioral abnormalities.Due to the lack of specific treatment, COVID-19 has strong infectivity and an increasing number of confirmed patients.Besides, patients are faced with unprecedented fear of death.Furthermore, the isolation mode makes patients fearful, lonely, and helpless. 13During the COVID-19 pandemic, patients undergoing hospital isolation suffer from intensified mental exhaustion, burnout, fear, depression, anxiety, insomnia and psychological stress.Such stress may exert a negative impact on the safety of patients and isolated personnel. 14he COVID-19 outbreak is a stressful life event that cannot be controlled.Isolating measures disrupt daily life 15 , it is important to evaluate and treat the negative emotions of the isolated personnel during the COVID-19 pandemic.This study proved that, age, gender, marital status, economic status and attitude towards isolation are main factors affecting the negative emotions of personnel undergoing hospital isolation.Therefore, it is crucial to consider these factors while planning effective intervention strategies to reduce the risk of poor mental health. 16Among isolated personnel, females are more susceptible to anxiety, depression and stress.Alemanno et al. 17  The results of MMSE, MoCA, Hamilton Depression Rating Scale and FIM showed that all patients need long-term psychological support and treatment to prevent the occurrence and aggravation of psychological diseases.Alkhamees et al. 18 believed that nearly a quarter of the sampled general population suffered from moderate to severe psychological effects throughout the COVID-19 outbreak in Saudi Arabia.Taking specific preventive measures can protect individuals' mental health.Public mental health strategies should be implemented in the early days of the COVID-19 outbreak.According to Wang et al. 19 , one third of adults among general population suffer from COVID-19-associated psychological disturbance.Joint efforts are urgently needed to intervene with high-risk groups.With the further spread of COVID-19 pandemic, it is particularly important to develop psychological intervention strategies and provide continuous intervention. 20mitations: The sample selection and sample size are limited due to limited time.Long time, extensive and indepth surveys and studies based on large sample sizes will be carried out in the future.In addition, personnel undergoing hospital isolation and centralized isolation will be grouped for comparison.The purpose is to identify more affecting factors to provide more refined or targeted medical interventions to isolated personnel due to the pandemic.

CONCLUSION
During the COVID-19 pandemic, anxiety, depression and stress increased to different extents in personnel undergoing hospital isolation, especially in females with poor economic conditions and poor attitudes towards isolation.Therefore, relevant personnel should provide necessary psychological counseling and social support to these people.In addition, different counseling methods should be taken according to different psychological problems of different objects, so as to timely solve the psychological problems of personnel undergoing hospital isolation.
