Background: In-hospital mandatory quarantine of asymptomatic and symptomatic COVID-19-infected individuals was part of the national control strategy used to prevent the spread of the COVID-19 outbreak in Jordan. This study aims to evaluate depression, associated stressors, and various coping methods used among adult quarantined COVID-19-infected individuals.
Methods: This cross-sectional study included all COVID-19-infected individuals who were obligatorily quarantined at King Abdullah University Hospital, Irbid, Jordan from March 15 to April 20, 2020. Symptoms of depression were assessed using the 9-item Patient Health Questionnaire after 10 days of quarantine. In addition, several questions regarding the patients’ sights with the health-care system, and coping methods were added. Demographic characteristics, clinical presentation, and comorbidities were collected from the medical records.
Results: Out of 91 quarantined COVID-19 patients, a total of 66 completed the survey, with a participation rate of 72.5%. The majority were relatively young; the mean ± SD age was 35.8 ± 16.2 years (range 18– 79), 59.1% were females and 47% were asymptomatic. A considerable proportion of patients (44%) reported symptoms of depression, with 21% were at high risk of major depressive disorder. Depression symptoms were significantly more common among females than males [PHQ-9 score ≥ 10: 13 (92.9%) vs 1 (7.1%), respectively; p=0.004]. The majority of patients (71.2%) reported having problems with health-care services. Insufficient involvement in making treatment decisions was the most commonly reported concern (59.1%). Patients who reported problems in maintaining privacy, reaching out to their physicians, or receiving conflicting information from the medical staff, had more symptoms of depression compared with the satisfied ones (p< 0.05). On the other hand, those who were receiving sufficient support from the family, friends, or medical staff during quarantine, were less likely to have depression symptoms (p< 0.05). Furthermore, symptoms of depression were less in patients who stayed in touch with others using phone calls, texting, or social media (p=0.024).
Conclusion: Symptoms of depression were common among both symptomatic and asymptomatic quarantined COVID-19 patients. The support of family, friends, and medical staff was an essential alleviating factor. Facilitating adequate communication may promote the mental well-being of COVID-19-infected patients and help in reducing the risk of depression during the in-hospital quarantine.

Introduction

Coronavirus is one of the major pathogens that primarily target the human respiratory system. In December 2019, China reported to the World Health Organization (WHO) multiple cases of unexplained lower respiratory tract infections. A coronavirus that is genetically related to the SARS virus was identified (SARS-CoV-2). This new viral syndrome named by the WHO as coronavirus disease 2019 (COVID-19). The epidemic spread within mainland China with a basic reproduction number (R0) estimated to be from 2.2 to 3.3 and a mortality rate of around 2.3%.13 In an effort to contain the spread of the COVID-19 infection and reduce its impact on the health-care system, the Jordanian ministry of health has adopted a quarantine system that mandated hospital admission of all laboratory-confirmed COVID-19 patients, including asymptomatic cases, and regardless of the severity of their illness.

Quarantine is a very old and effective containment tool, previously used to contain the spread of contagious diseases like the plague and influenzas. It is derived from the word “Quarantenaria” which means forty days.4 As the COVID-19 pandemic rapidly sweeps across the world, it is inducing considerable psychological effects in the population. Although variable degrees of fear, anxiety, anger, and depression are suspected to be observed in COVID-19-infected population during their quarantine, most studies in the literature focused on the psychosocial disturbances among health-care providers and potential contacts of COVID-19 patients. Data indicated high rates of depression, anxiety, and insomnia, posttraumatic stress symptoms (PTSD), and substance use disorders among health-care workers dealing with COVID-19 patients.58 Studies of individuals who had been quarantined for different contagious diseases showed an increased prevalence of depression, emotional disturbances, stress, insomnia, and irritability.911 There are scarce data to describe such an impact on the quarantined COVID-19-infected population.

To date, this is the first study that aims to evaluate depression, various stressors, and associated factors and coping mechanisms among individuals with confirmed COVID-19 infection during their obligatory and prolonged in-hospital quarantine.

Methods

Outbreak Response

Jordan is a Middle Eastern country with a population of 11 million. After the WHO declared COVID-19 as pandemic disease, the Jordanian Ministry of Health issued a health-alert that patients with flu-like symptoms and recent travel to endemic countries should be screened for SARS-CoV-2 infection. After the first case of COVID-19 infection was reported in Jordan on March 2, 2020, a policy of extensive contact tracing followed by a screening of suspicious contacts, and mandatory hospital admission of all laboratory-confirmed COVID-19 patients was placed. This was supported by a countrywide strict lockdown and a nightly curfew. The borders were sealed off and all traveling to and from Jordan was stopped on March 15, 2020. A Royal Decree has been issued approving the implementation of the National Defense Law on March 17. These strict outbreak response measures applied at early stages probably contributed to the lenient nature of this outbreak and reducing its impact on public health.12

Participants and Study Design

This cross-sectional, survey-based, single-center study included all adults with laboratory-confirmed COVID-19 infection that were obligatorily quarantined at King Abdullah University Hospital (KAUH), Irbid, Jordan from March 15 to April 20, 2020. Patients younger than 18 years were excluded. COVID-19 cases were confirmed by a positive SARS-CoV-2 real-time reverse transcriptase-polymerase chain reaction assay (RT-PCR), from a nasopharyngeal swab specimen. Specimens were collected and analyzed according to the Centers for Disease Control and Prevention (CDC) guidelines. All clinical specimens were tested with the assay developed by the CDC, targeting the N1 and N2 genes.13

Clinical charts and nursing records of all included patients were reviewed, and demographic characteristics, clinical presentation, and comorbidities were recorded. The degree of symptoms of depression experienced by participants was assessed using the 9-item Patient Health Questionnaire (PHQ-9) after 10 days of quarantine, and answers were documented by two interviewers. PHQ-9 consists of nine items based directly on the diagnostic criteria for major depressive disorder in the DSM-IV. Based on participant response to the frequency of any particular symptom (0 = not at all, 1 = several days, 2 = more than half of the days, 3 = nearly every day), a total score ranging from 0 to 27 was obtained, with higher scores indicating patients’ increased depression severity. PHQ-9 is a dual-purpose instrument that can establish major depressive disease diagnosis as well as grade the severity of depression. PHQ-9 score ≥10 had a sensitivity of 88% and a specificity of 85–88% for major depressive disorder.14,15 Also, PHQ-9 has excellent internal reliability and test-retest reliability.14 The total score of the PHQ-9 questionnaire was interpreted as follows: normal (0–4), mild (5–9), moderate (10–14), and severe (15–21) depression.14,15 Also, five questions were obtained from the 15-item Picker Patient Experience Questionnaire (PPE-15) to evaluate patients’ experiences with specific dimensions of in-patient care during their quarantine in the hospital.16,17 The patients’ answers for these questions were coded as a dichotomous “problem score”, indicating the presence or absence of a problem. A problem is defined as a piece of health care that could, in the eyes of the patient, be improved upon (Appendix 1).16,17 Furthermore, various coping interventions adopted by the patients during their quarantine were addressed and analyzed in relation to the degree of depression.

Quarantine was ended and patients were discharged home when they met all clinical and virologic cure criteria of the CDC which includes; resolution of fever without the use of fever-reducing medication, improvement in respiratory symptoms, and negative results of at least two consecutive nasopharyngeal swab specimens collected ≥24 hours apart.18

Approval from the Institutional Review Board (IRB), and the clinical research ethics committee of King Abdullah University Hospital and Jordan University of Science and Technology was received before the initiation of this study. Written informed consent for participation in this study was obtained from all recruited patients. Participants could terminate the survey at any time they desired. The survey was anonymous, and confidentiality of information was assured.

Statistical Analysis

The data were described using frequency and percentage for categorical variables and mean ± standard deviation for continuous variables. A chi-square test or Fisher’s exact test was used to assess the association between categorical variables, whereas continuous variables were analyzed by the Student’s t-test or ANOVA. The total scores of PHQ-9 were not normally distributed and so are presented as medians with interquartile ranges (IQRs). A p-value of less than 0.05 was considered statistically significant. The IBM Statistical Package for Social Sciences Software (SPSS) for Windows, version 25.0 was used for data processing and analysis.

Results

After an outbreak was recognized on March 17th, 2020, a total of 91 laboratory-confirmed COVID-19 patients were admitted to KAUH by April 2, 2020. Ten patients were excluded from the study as they were younger than 18 years and two patients were unable to participate because of their critical medical illnesses. Eleven patients declined the survey for privacy concerns, while two refused to give reasons for declining to participate in the study. A total of 66 patients were included in the study, with a participation rate of 72.5%. The majority of patients were relatively young; the mean ± SD age was 35.8 ± 16.2 years (range 18–79) and 59.1% were females. About half of the patients (48.5%) were cigarette or waterpipe smokers, and 20 (30.3%) were obese (BMI ≥ 30 kg/m2). Sixteen (24.2%) had chronic illnesses; ischemic heart disease (6.1%), hypertension (15.2%), dyslipidemia (7.6%), and diabetes mellitus (7.6%). About half of the patients (47%) were asymptomatic on admission and did not develop any symptoms during quarantine (Table 1).

Table 1 Demographic Characteristics, Clinical Features, and Severity Categories of Depression Among Quarantined COVID-19 Patients

The feedback from patients regarding their experience with specific dimensions of the health-care system during their quarantine inside the hospital is presented in Table 2. Forty-seven patients (71.2%) reported having problems with the provided medical care. The largest proportion of problems (59.1%) were related to the insufficient involvement of patients in the decisions regarding their medical care and treatment plans. Also, 30.3% reported problems in reaching out to their physicians, 18.2% reported receiving conflicting information from doctors and nurses and 10.6% reported problems related to privacy during the quarantine. The smallest proportion of problems (7.6%) were observed for the item asking whether doctors talked in front of them as if they were not there.

Table 2 Patients Sights with the Health-Care System During Quarantine Inside the Hospital

When patients were asked about “the most preferred method to cope for feeling isolated during quarantine”, 47% of the patients answered that “staying in touch with their close ones by phone calls and texting helped the most”. Using social media, mostly Facebook and YouTube, was the second most commonly used coping method (28.8%). Moreover, watching television and praying were reported as the preferred coping methods by 10.6%, and 7.6% of patients, respectively.

Most patients (80.2%) agreed that receiving emotional support from others was the most important element to help them feel socially connected during their in-hospital quarantine. The largest proportion of patients reported family as the main source of support during quarantine (65.2%), followed by friends (50%), medical staff (39.4%), and other quarantined COVID-19 patients (9.1%).

The Severity of Depression and Associated Factors

A considerable proportion of patients (44%) reported symptoms of depression, with 21% were at high risk of major depressive disorder as their PHQ-9 score ≥10. Depression symptoms were mainly reported by females [PHQ-9 score ≥10 among women vs men: 13 (92.9%) vs 1 (7.1%); p=0.004]. Although variable degrees of depression (mild, moderate, and severe) were observed in 19 patients of the symptomatic group (65.5%), compared with 10 patients (34.5%) who were asymptomatic, there was no significant difference between the two groups (p= 0.072). Nonetheless, patients who reported problems or concerns regarding maintaining their privacy (10.6%), reaching out to their physicians (30.3%), or received conflicting or confusing information from the health-care providers (18.2%) were found to have more depression symptoms (p=0.040, p=0.042, p=0.018; respectively) (Table 3). On the other hand, patients who reported receiving adequate emotional support from their families (65.2%), friends (50%), or the medical staff (39.4%) during quarantine, were less likely to have symptoms of depression in comparison to patients without such support (p=0.015, p=0.025, p=0.012; respectively). Patients who chose “staying in touch with others or using social media” as their most preferred ways to cope with quarantine were less likely to have symptoms of depression (Figure 1). Interestingly, among Television (TV) watchers, those who were following COVID-19 related news programs or interviews were more likely to have symptoms of depression, in comparison to those watched random shows or entertainment programs such as movies, TV-shows, or series (p=0.023) (Figure 2).

Discussion

Most studies focused on the clinical presentation and laboratory findings of COVID-19 hospitalized patients with less attention to the mental health effects of in-hospital quarantine.12,19,20 This study demonstrates that symptoms of depression were commonly reported among hospitalized COVID-19 patients during their mandatory quarantine, regardless of the severity of their illness. The support and social interaction provided by family, friends, and medical staff were an important alleviating factor during the quarantine of this study population as higher levels of depression were observed among those without such support. Although social media mitigated the effects of quarantine for many patients, most patients compensated for their feeling of isolation by staying-in-touch with family and friends using phone-calls and texting. On the other hand, watching or reading news about COVID-19 during quarantine was associated with higher levels of depression.

The Centers for Disease Control and Prevention (CDC) had warned that COVID-19 outbreaks can be stressful; and patients’ fear and anxiety about their health can be overwhelming.21 Fear and anxiety of the health-care providers from having close encounters with COVID-19 cases resulted in limited close comprehensive face-to-face encounters. Unfortunately, this unintended behavior has generated a feeling of despair among COVID-19 patients who implied multiple drawbacks including insufficient time spent by the health-care providers with less opportunity to talk to the caring medical teams and disconnected communication between the members of the caring medical team and the patients. Lack of clarity about different risk levels and poor communication were cited as a stressor in developing the psychological disorder in quarantined patients.2224 Privacy concerns while discussing treatment plans, receiving conflicting reports from the caring medical team, and difficulty in reaching out to physicians were among the most reported health-care problems. Patients who reported these problems were more likely to have symptoms of depression.

Quarantine is one of several public health measures to prevent the spread of infectious diseases. Quarantine restricted measures were regularly associated with negative psychosocial effects and distress that may include depression, anxiety, anger, stress, social isolation, loneliness, PTSD, and stigmatization.9,25 Sense of uncertainty due to fear for one’s health or the health of loved ones, disruption to daily life, and isolation as a result of separation from others, were all experienced.26 The high transmission rate of COVID-19 and its high morbidity and mortality may have intensified the perception of personal danger and escalated the risk of developing the psychological disorder than caused by quarantine alone. Those quarantined for longer than 10 days showed significantly higher posttraumatic stress symptoms than those quarantined for less than 10 days.27 A study examined symptoms of depression 3 years after quarantine and found that 9% of the whole sample reported high depressive symptoms.28 Negative psychosocial outcomes were also reported among health-care workers who are treating patients with coronavirus disease.5,22 Addressing the possible negative impact of quarantine is an important aspect of maintaining the overall health well-being and should be part of the overall assessment and medical care plan provided to patients requiring quarantine.

This study has several limitations. First, the sample size is small which limits the generalization of our findings and increases the risk of selection bias. Second, the study was carried out after 10 days of quarantine and lacks longitudinal follow-up. Some patients remained in quarantine for longer periods with a progressively stressful situation which might have led to a higher risk of depression and stress. Third, although the response rate of this study was 72.5%, response-bias may have occurred if the non-responders refused the survey as they were feeling uninterested or depressed to participate. Fourth, potential differences need to be considered as this study did not have a control inpatient group to compare the prevalence and severity of depression.

Conclusion

Symptoms of depression were commonly reported among COVID-19 patients during their in-hospital obligatory quarantine regardless of the severity of their disease. Receiving the support of family, friends, and medical staff was an essential alleviating factor, and connecting with them was the most preferred coping method. On the other hand, following the media for news about the coronavirus correlated with higher levels of depression symptoms. These findings suggest that administrative measures to facilitate adequate communication between these patients and their families, friends, and medical staff and limiting coronavirus news exposure during in-hospital quarantine may lower the risk of depression. Further large epidemiological studies and clinical trials are needed to investigate the mental health effect of the quarantine and how to reduce it.
