Background Global pandemic resulted from the coronavirus disease-19 (COVID-19) demands mental health concerns on the affected population. We examine the time-course shift of psychological burden among suspected and confirmed COVID-19 patients. Methods Participants with suspected or confirmed COVID-19 were included in the cohort. Consecutive surveys were conducted upon hospital admission, discharge, and during outpatient follow-up by adapting the 5-item brief symptom rating scale (BSRS-5) assessing psychological symptoms including anxiety, depression, hostility, interpersonal sensitivity, and insomnia. The sixth measure to observe suicidal ideation was also included. Results A total of 109 eligible patients participated in the study, in which 83.49% reported no distress upon hospital admission, while 2.75%, 3.66%, and 10.1% patients were assessed as being with severe, moderate and mild psychological distress, respectively. Overall, age, sex, and history of contact did not significantly differ between patients with and without psychological distress. Multivariate logistic regression revealed that patients admitted during April-May (OR: 7.66, 95% CI: 1.46-40.28) and presented with symptoms including sore throat (OR: 4.24, 95% CI: 1.17-15.29) and malaise (OR: 5.24, 95% CI: 1.21-22.77) showed significantly higher risk of psychological distress. Cough symptom interestingly showed lower risk of emotional distress (OR: 0.25, 95% CI: 0.08-0.81). Subsequent surveys upon hospital discharge and during outpatient follow-up revealed steadily declining distress among all cohort. Conclusion At least 16.5% of our cohort reported psychological distress upon hospital admission, with distinct time-dependent decline. Access to mental health support, alongside with promoting positive activities for good mental health are pivotal for those directly affected.

December 2019, and emerged as global pandemic with over 21.6 million confirmed cases, and a total of 0.77 million deaths globally as of August, 2020 (1, 2) . The high burden of unknown, possibly fatal-disease, as well as the need for isolation to contain transmission are having an immense impact on both physical and mental health in affected population (3) . The potential fallout on mental health is likely to be profound on those directly affected by the disease as well as people at risk of exposure (4) . During the severe acute respiratory syndrome (SARS) epidemic in 2003, mental health casualties include 30% increase of suicide in elderly (5) , 50% recovered patients who remained anxious (6) , and 29-39% health-care workers who experienced emotional distress (4, 7) . In the long run, those survived were also at risk of post-traumatic disorder and depression (8, 9) . A nation-wide mental health survey proposed that the major psychological impact of COVID-19 pandemic is likely to be increased social isolation and loneliness, which are strongly associated with anxiety, depression, self-harm, and suicide attempts in the future (10) , therefore immediate measures to report the rate of mental health issues as well as its mechanism and possible interventions are of great necessity.

In this study, we aim to assess suspected and confirmed COVID-19 patients upon hospital admission, discharge, and during outpatient follow-up to evaluate the time-course shift of psychological burden. We expected that adequate mental health care and comprehensive evaluation protocol during in-hospitalization for patients staying in isolation room have positive impact towards ease of psychological burden. The result is expected to provide insight on the rate of psychological distress as well as the progression on the immediately affected population, and raise potential intervention to limit prolonged burden.

Adult patients (≥20 years old) with suspected or confirmed COVID- 19 

J o u r n a l P r e -p r o o f In concern to the importance of mental health support in both suspected and confirmed patients, we initiated a periodic mood disturbance survey for our hospitalized patients to immediately address and commence intervention. Visit and consultation with social workers, psychologists, or psychiatrists were arranged if deemed necessary by the attending physicians, or when requested by the patients. Social interaction and as nearly-normal as possible daily activity were encouraged, by communicating the patients' interest and providing them books, study materials, oil painting, as well as entertainment including play-station games. Patients were allowed to communicate with their family and friends through phone calls and video chats.

Patients are encouraged to maintain physical activities by simple daily exercise and Wii games.

The mental health evaluation and support program were integrated components of the holistic management initiatives for COVID-19 which were guided by the COVID-19 Operation Committee of Wan Fang Hospital.

Consecutive surveys for psychologic distress were conducted at three time points: within 24 hours after hospital admission, the day before or the same day of discharge, and outpatient follow-up 7 days after discharge. The surveys were conveyed using the video call when the patients were kept in negative pressure isolation, face-to-face when they were to be discharged, and phone call during outpatient follow-up.

We retrospectively analyzed the psychological distress of patients admitted for suspected or confirmed COVID-19. The Joint Institutional Review Board of Taipei Medical University approved the study and waived the informed consent (N202007039).

We adapted the 5-item brief symptom rating scale (BSRS-5), a self-administered questionnaire to assess psychological symptoms including anxiety, depression, hostility, interpersonal sensitivity, and trouble on falling asleep (insomnia). For suicide prevention, Taiwan adds the sixth additional measurement asking the subject about any urge of suicide attempts (11) . The score for each item ranges from 0 to 4, with 0 being not at all; 1, a little bit; 2, moderately; 3, quite a bit; and 4, extremely. A total score of more than 14, or any score of 2 or more on the suicidal ideation part indicates severe mood disorder, while scores between 10-14 and 6-9 indicate moderate and mild mood disorders, respectively (12) . This adapted BSRS-5 is commonly used in Taiwan for rapid psychological disorder screening with high validity and reliability among general community population as well as patients with psychiatric or medical diseases (11) (12) (13) (14) (15) .

First, the demographic data were expressed as means and standard deviations (sd) for continuous variables, and counts and percentages for categorical variables. To determine the difference between the patients with and without psychological distress, the t-test for the continuous variables, and Chi-square test (or Fisher exact test) for the distributions of categorical variables were used, as appropriate. Next, univariate and multivariate analyses i.e. generalized linear models (GLM) using the "logit" link function and the psychological distress (BSRS-5 ≥ 6) as the response variable having a binomial distribution (11) , were applied to identify the associations between the psychological distress and potential risk factors, including all clinical demographics, main reasons to alert COVID-19, and clinical presentations among patients J o u r n a l P r e -p r o o f suspected or confirmed of COVID-19. The associations were expressed as the odds ratios (OR) and 95% confidence intervals (95% CI). Last, the GLM using the "identity" link function and BSRS-5 as the response variable having a normal distribution, and the generalized estimating equations (GEE) were conducted to assess the time trend of psychological distress at hospital admission, discharge and during outpatient follow-up. Statistical analyses were performed using SAS version 9.4 (SAS, NC, USA). The significance level was set at 0.05.

Among the 131 patients admitted for suspected or confirmed COVID-19 during the study period, 22 patients with previously documented dementia and old cerebral vascular accidents rendering them unable to engage with the survey questions were excluded in the study. A total of 109 patients participated in the study (Table 1) . One patient lost to follow-up after discharge and the rest 108 patients completed all three consecutive surveys. Among all participating cohort, the mean age was 37.06 years-old (SD ± 18.22) and 60 were male (55.05%). The most prevalent accompanying chronic physical diseases were hypertension (15.6%), dyslipidemia (9.17%), chronic obstructive pulmonary disease/asthma (9.17%), and diabetes mellitus (7.34%). Four patients (3.7%) were confirmed with COVID-19 and had appropriate management according to the Taiwan CDC protocol.

All 109 subjects were categorized into two groups based on the total score of 0-5 and ≥6, indicating none and presence of psychological distress, respectively. A total of 91 (83.49%) and 18 patients (16.51%) reported none and presence of psychological distress upon hospital admission, respectively. Among those with psychological distress, 3 (2.75%), 4 (3.66%), and 11 (10.1%) patients were assessed as being with severe, moderate and mild psychological distress, J o u r n a l P r e -p r o o f respectively. Overall, age, sex, chronic physical diseases and history of contact did not significantly differ in both groups, however, the patients with psychological distress reported less cough (Table 1) . Social workers interviewed the 18 subjects reporting physiological distress, and the three patients with severe psychological distress reporting moderate suicidal ideation were assigned for consultation with psychologist. Follow up psychiatric consultation was arranged for one patient.

Univariate logistic regression analysis revealed that patients admitted during April-May, as well as the presence of general malaise showed higher risk to psychological distress (OR: 4.60, 95% CI: 1.12-18.95; and OR: 3.50, 95% CI: 1.01-12.11, respectively). Further analysis applying multivariate models revealed that patients admitted during April-May showed significantly higher risk of psychological distress (OR: 7.66, 95% CI: 1.46-40. 28 ). In addition, the presence of symptoms including sore throat and general malaise were associated with higher risk of distress 

This is the first study, to our knowledge, to conduct a time-course surveys among hospitalized patients with suspected or confirmed COVID-19. In summary, patients were assessed at least three consecutive surveys during hospital admission, on discharge, and during outpatient follow-up. Five elements of the BSRS-5 including anxiety, depression, hostility, interpersonal sensitivity, and trouble on falling asleep, as well as additional survey on suicidal ideation were assessed. The prevalence of psychological distress (defined as BSRS-5 ≥6) among general population in Taiwan was reported to be 8.33% (15) . Our result showed that 16.5% of our cohort, consisted of 16.2% and 25% of suspected and confirmed cases, respectively, reported psychological distress upon hospital admission. The number is slightly higher compared to a previous study indicating 12% of the general Taiwanese population reported psychiatric distress over the impact of COVID-19 pandemic (16) . Upon hospital discharge and outpatient follow-up, the psychological burden showed a distinct time-dependent decline.

A previous study reported a considerably low prevalence on psychiatric disorder among the general population in Taiwan, which may reflect a possible under-treatment (17) . During a pandemic, mental health is one of the crucial factors that will influence the way any given person responds to a pandemic, including COVID-19. Uninterrupted mental health care services should be attained, even for the subthreshold and mild psychological responses, as they may lead to heightened stress reaction (18) . Studies of public psychological states in China during the COVID-19 pandemic reported a rate of 6-35% and 17-20% population who experienced anxiety and depression, respectively (19, 20) , in which as high as 28.8% were moderate to severe anxiety symptoms, and 8.1% moderate to severe stress level (21) . For those directly affected, increased social isolation, as well as worries and uncertainties about a pandemic may translate into a range J o u r n a l P r e -p r o o f of emotional reactions including distress, both in the acute and long-term phases (10, 22) . A recent study reported over 34% and 28% hospitalized patients had anxiety and depression during admission, respectively, which was correlated with less social support (23) . Additionally, female gender (19, 24) , younger age (19) , accompanying chronic disease, and previous psychiatric history population (25) were found to be more susceptible to present with anxiety and depression.

More importantly, due to the proven negative impact of social stigma on patients contracted a transmissible disease during a pandemic (26) , Taiwan government strictly protect the identity and regulate the privacy of all suspected and confirmed cases. Of those suspected cases, mood disturbances were prominently reported upon suspect notification and generally relieved following definite negative diagnosis result. Therefore, we proposed that rapid diagnosis confirmation may benefit in lowering emotional burden. In addition, sufficient knowledge and consensus on epidemic prevention, as well as accessible and accurate source of information contributed to better psychological well-being (27) and control of COVID-19 in Taiwan (28) .

The subjects involved in our study were limited to uncomplicated patients with mild clinical symptoms, thus may not reflect the entire spectrum of psychological distress of COVID-19 patients. Although emotional distress has been correlated with the lack of social support, this was also not measured in our study. Therefore, further study to include patients with distinct disease severities, along with evaluation of social support are deemed necessary. In addition, qualitative analyses, instead of quantitative, are warranted to further probe the underlying source of emotional disruption.

Mitigating risks of emotional distress among vulnerable group, as well as enabling access to mental health support, privacy protection, alongside with promoting positive activities for good mental health are pivotal. For those directly affected, an effective communication should be J o u r n a l P r e -p r o o f established to deliver an adequate information about their current situation and progress, which may relieve the emotional burden from being a disease suspect and socially isolated. Moreover, rapid diagnosis confirmation may benefit in alleviating the worries among suspected patients.
