Summary

Background: There is limited knowledge on the psychological implications of COVID-19 among hospitalized patients and their close relatives. Moreover, evidence-based psychological interventions targeting hospitalized COVID-19 patients and their relatives are currently lacking.

Objective: To test a minimal psychoeducational intervention versus standard of care for reducing anxiety among hospitalized COVID-19 patients.

Methods and analysis: The trial is a Randomized Controlled Trial (RCT) with a 1 month and 3 month follow-up. Hospitalized COVID-19 patients are consecutively included at admission and randomized 1:1 to either an intervention or control group. Patients randomized to the intervention group will receive a minimal psychoeducational intervention just prior to discharge from the hospital. The goal of the intervention is that patients will be prepared and learn to interpret and react to physical and psychological symptoms that are related to recovering from a COVID-19 infection. Data is collected using standardized and validated patient reported outcome measures (PROMs) to assess mental health outcomes. The primary outcome is patient reported anxiety as assess by the Hospital Anxiety and Depression Scale.

Perspectives: This study will provide a comprehensive understanding of the psychological implications of the COVID-19 outbreak. If successful, the minimal intervention is easily implemented in daily clinical practice.

Description

INTRODUCTION Around 20% of people with COVID-19 becomes seriously ill with pneumonia and multi-organ failure, requiring hospital admission to relieve the symptoms and reduce mortality. To avoid any spreading of the virus, hospitalized COVID-19 patients are isolated. Thus, patients hospitalized with COVID-19 are limited in their social support and their only in-person contact is with healthcare staff in full personal protective equipment. Several studies highlight that isolation due to infection may have negative psychological implications. Moreover, Patients with confirmed or suspected COVID-19 may experience fear of the consequences of the infection. A high prevalence of persistent mental health problems has been found among patients during infectious disease outbreaks such as the 2003 outbreak of Severe Acute Respiratory Syndrome (SARS). Researchers and policy makers have highlighted that the psychological impact of the COVID-19 pandemic must be recognized alongside the physical symptoms for all those affected. Moreover, evidence-based evaluations and mental health interventions targeting hospitalized COVID-19 patients and their relatives are at present lacking. If left untreated, these psychological symptoms may have long-term health effects on patients and require treatment adding to the cost burden of managing the illness.

OBJECTIVE The objective of this project is to test the efficacy of a minimal psychoeducational intervention versus standard of care at discharge for reducing symptoms of anxiety in hospitalized patients during the COVID-19 outbreak

METHODS Design This is a Randomized Controlled Trial (RCT) among hospitalized COVID-19 patients.

Hypothesis The primary hypothesis is that a minimal psychological intervention will reduce anxiety as assessed by the Hospital Anxiety and Depression Scale (HADS) subscale for anxiety (HADS-A) by 1.5 points from baseline to follow-up 1 month after discharge from hospital. The estimated decrease in HADS-A is based on the clinically important difference found in patients with COPD and isolation studies.

Study population Patients will be recruited from the Department of Infectious Diseases and the COVID-19 isolation wards at Copenhagen University Hospital, Hvidovre; one of the major hospitals treating COVID-19 patients in Denmark.

Eligible patients are consecutively identified at time of admission. Included patients are randomized 1:1 to either a psychoeducational intervention or standard care delivered at discharge.

Sample size The primary outcome of interest is the intra-individual differences in HADS-A scores between baseline and follow-up 1 month post discharge. The design is paired with a power of 0.80 and an at p=0.05. To identify a difference of 1.5 points, which is the minimal clinically important difference based on COPD and isolation studies, with an SD of 2.5 points, 25 patients are required in each group. Since the trial population consists of severely ill patients with high morbidity and mortality rates 2, approximately 30% of the sample are estimated to drop out. Thus, the RCT study requires 66 patients, with 33 in each group.

Intervention at discharge Patients randomized to the intervention group will receive a minimal psychoeducational intervention just prior to discharge from the hospital. The goal of the intervention is that patients will be prepared and learn to interpret and react to physical and psychological symptoms that are related to recovering from a COVID-19 infection. The intervention consists of both written and verbal information. While both the written and verbal information will be primarily targeted the patient, the role of relatives and their possible reactions will be part of the dialogue. A manual describing the content and procedures of the intervention will be developed to ensure that the intervention is both replicable and transparent. The intervention has a planned duration of 30 minutes and will be conducted by a designated study affiliated researcher, who has a background in healthcare (i.e. nurse or medical doctor).

Standard of care at discharge Standard of Care at discharge of patients with COVID-19 from hospital is to inform the patients whom to contact in case of worsening of the physical condition, such as increasing e.g. shortness of breath, and of precautions regarding further isolation to avoid infection of household and other contacts, if relevant. Information regarding the patients psychological condition is not part of a standard conversation at discharge.

Blinding Due to the nature of the intervention, the RCT trial is not blinded, but the outcome measures are masked for health professionals and staff until the end of the study.

Data collection Data is collected using standardized questionnaires at four timepoints; baseline completed within 48 hours after admission (T0), at discharge, but prior to intervention (T1), 1 month (T2), 3 months (T3), and 12 months (T4). Patients will answer the questionnaires electronically in REDCap or via phone interview conducted by a study nurse or medical student. Clinical data is collected from the medical records and entered into the REDCap database.

The following internationally well validated PROMs will be used to assess mental health/distress:

  • Anxiety and depression will be assessed using the Danish version of the HADS. The primary outcome in the RCT study is anxiety measured by HADS-A.
  • Perceived stress is measured using the Perceived Stress Scale - 10 item (PSS-10).
  • Harvard Trauma Questionnaire (HTQ) is used to assess subjective distress caused by traumatic events.
  • Health related quality of life is measured by SF-12, a short version of the Medical Outcomes Study (MOS) 36-item Short-Form Health Survey SF-36.

Sociodemographic and clinical variables The following demographic and clinical data are collected from the patients records: age, gender, marital status, residence in nursing home, medicine, smoking status, BMI, previous history of psychiatric illness, physical symptoms, and clinical parameters such as Temperature (>/> 38C); demand of oxygen support (< 5 litres O2/minute; 5-10 litres O2/minute; >10-30 O2/minute or need for mechanical ventilation). Biochemical parameters (Hemoglobin, White Blood Cell (WBC) count, lymphocyte count, Lactate Dehydrogenase, Alanine Amino Transferase (ALT), CRP). Length of hospital stay is collected at discharge. Information regarding contact to general practitioner and current psychological treatment outside of the study is collected during follow-up.

Statistical analysis Descriptive statistics of demographic characteristics at baseline (T0) will be computed. The primary analysis for the RCT study will be performed on the basis of the intention-to-treat principle. Baseline data for the two groups will be compared with Student's t test, the chi-square test, or nonparametric tests. To analyse within group differences in outcome scores, a Students t test or Wilcoxon rank-sum test will be used. A mixed regression model will be used to assess the change within-group and between groups over time. The co-variables included in the models will be chosen based on an a priori hypothesis, the bivariate analysis and clinical relevance. Analyses will be performed using the STATA 13 software and in collaboration with an experienced statistician. All reported p-values are two-sided using a significance level of 0.05.

ETHICAL CONSIDERATIONS The study has been approved by the Danish Data Protection Agency [P-2020-349]. The national Health Research Ethics Committee has assessed the intervention as not being a significant biomedical intervention [jr. nr. 20025879]. All participating patients will provide written informed consent before any data collection.

TIME SCHEDULE This is a two-year study initiated as soon as possible and no later than mid April 2020.

DISSIMINATION Publication of positive, neutral or negative results in international, peer-reviewed journals will be sought. In addition, results will be communicated at relevant scientific meetings and conferences.

PERSPECTIVE The results from this study have a number of important potential implications. First, by quantifying the magnitude of psychiatric symptoms among hospitalized COVID-19 patients, potential risk factors associated with these symptoms can be identified. Second, there is a need to develop and test the efficacy of minimal psychological intervention for reducing psychiatric morbidity among COVID-19 patients. Providing psychological treatment and support may reduce the burden of comorbid mental health conditions both short and long-term. The challenge is to provide mental health services in the context of patient isolation. Hence, the intervention is designed to give healthcare professionals an instrument that is clinically applicable and easy to implement even in isolated patients. Finally, the longitudinal design of the study capturing experiences over time, can be used to identify when in the trajectory psychological interventions are most needed.
