Randomized Controlled Trial of the Mindful Compassion Care Program in Reducing Psychological Distress Amongst Nurses During the COVID-19 Pandemic

The Effectiveness of the Mindful Compassion Care Program (MCCP) in Reducing Burnout and Psychological Distress Amongst Frontline Hospital Nurses During the COVID-19 Pandemic: a Randomized Controlled Trial

Recent studies have shown that nurses have been more affected by the COVID-19 pandemic than any other group of hospital workers in terms of anxiety, depression, and burnout. Several clinical studies had previously demonstrated the effectiveness of mindfulness and compassion interventions in reducing burnout and emotional distress amongst healthcare professionals. A parallel-group randomized controlled trial will assess the feasibility, acceptability, and efficacy of a mindfulness and compassion-focused programme on frontline nurses who had been working during the COVID-19 pandemic. Seventy-two participants will be divided equally into an intervention group and a control group. Primary outcome will be assessed using the Emotional Exhaustion subscale of the Maslach Burnout Inventory General Survey (MBI-GS). Secondary outcomes will be measured by the Cynicism and Professional Efficacy subscales of the MBI-GS; the Patient Health Questionnaire (PHQ-9); the Generalized Anxiety Disorder (GAD-7); the Insomnia Severity Index (ISI); the Impact of Stressful Events (IES-R); the Perceived Stress Scale (PSS); the Five Facet Mindfulness Questionnaire (FFMQ); and the Forms of Self-Criticising/attacking and Self-Reassuring Scale (FSCRS). The study aims to fill a gap in the literature and present a scientifically validated intervention for those healthcare professionals most exposed to the stressful conditions of working during the COVID-19 pandemic.

BACKGROUND. From the beginning of the COVID-19 pandemic, healthcare workers (HCWs) worldwide experienced overwork, increased health risks in the absence of clear guidelines, and the reorganisation of their activities. These factors, combined with exposure to a condition of increased mortality and a sense of uncontrollability, have led to growing incidences of burnout, anxiety, depressive symptoms, and a reduced investment of energy in the professional sphere. Nurses were amongst the HCWs most exposed to the negative psychological effects of the COVID-19 pandemic, particularly those working in departments most involved in the treatment of COVID-19 patients, such as intensive care, infectious disease, and pulmonary units and emergency rooms. Several studies have shown the effects of mindfulness interventions in reducing burnout and emotional distress among HCWs in the pre-COVID 19 era. Mindfulness can be defined as an awareness of present-moment thoughts, feelings, and bodily sensations through intentional and non-judgemental attention. It is a state of consciousness that allows the mind and body to build a relationship of harmony and balance, a predisposing element for the condition of well-being. Studies investigating the diffusion of clinical models based on mindfulness have allowed us to hypothesize that it can play an important role in emotional self-regulation. It can, therefore, be argued that mindfulness allows one to reduce suffering and create a healthy mind by using self-processing processes and modulating awareness of self and one's emotional states, behaviours, as well as relationships with others. The ability to manage suffering, for example of patients and caregivers, stems from an empathic and emotional attunement known as compassion to the suffering of the another person. Compassion can be defined as the awareness of one's own and others' suffering and the intention or motivation to alleviate it. It has been associated with the capacity to adjust to distressful experiences during dramatic events such as pandemics, and amongst HCWs in particular.

AIMS. Studies evaluating the efficacy of mindfulness among HCWs s working during the current COVID-19 pandemic are rare, though some are in progress. The present project is based on the results of a longitudinal study that assessed the psychological impact of the COVID-19 pandemic on HCWs at the Verona University Hospital Trust during the lockdown phase and after one year later. The present project proposed here aims to implement and evaluate the feasibility, acceptability, and effectiveness of a preliminarily tested intervention that integrates the most widely used and scientifically validated mindfulness protocols such as mindfulness-based stress reduction, mindfulness-based cognitive therapy, and compassion focused therapy, in a healthcare context (the Verona University Hospital Trust) during the COVID-19 pandemic. The purpose of the intervention is to reduce burnout and psychological distress among frontline nurses involved in the clinical management of COVID-19 patients. The study will be conducted at the Verona University Hospital Trust (Azienda Ospedaliera Universitaria Integrata [AOUI]), the second-largest hospital in Italy in terms of the number of beds and the fifth largest in terms of admissions. The trust employs 6,000 people, including nearly 2,000 nurses. On 17 March 2020, the Veneto regional government converted part of the hospital into a COVID-19 hospital. Dedicated pathways for both suspected and confirmed COVID-19 cases were established within the hospital, as well as in other hospital units located in clearly restricted areas devoted to the treatment of COVID-19 patients.

DESIGN. Participants will be randomly assigned to one of two groups: the experimental group will receive the Mindful Compassion Care Program (MCCP), and the control group will be allocated to a waiting list (WL). The effectiveness of the experimental intervention will be assessed by comparing the changes in the level of burnout at the end of the treatment and after 1-month later. Other psychological dimensions will also be investigated (i.e., anxiety and depressive symptoms, post-traumatic symptoms, insomnia, perception of stress, mindfulness skills and evaluation of self-criticism and self-reassurance).

Enrollment procedure: The study description and the invitation to participate will be published in the hospital's newsletter and will be emailed to the nurses' address by the Verona Hospital Trust Administration. All nurses who express an interest in participating will receive (via email) an information sheet containing all the project details together with a link to the online screening questionnaire. They will find the participant consent form and the consent form for the use and processing of personal data on the same page. The screening questionnaire will allow us to assess whether the participant meets the inclusion criteria. If they do, they will be added to a temporary list of candidates; if they do not, they will be excluded from the trial. Participants will be randomly allocated to the intervention or the WL control group with an allocation ratio of 1:1. Participants allocated to the experimental group will receive the intervention immediately after randomization, and those assigned to the control group will be offered the same intervention 6 months after. The experimental intervention will take place over 6-weeks. The pre-test, post-test, and 1-month follow-up will be carried out at the same time for both study groups. The trial will begin in April 2022. Enrolment will end as soon as the expected number is reached (36 for the intervention group and 36 for the control group). Before the intervention, participants randomly assigned to the intervention group will be divided into three subgroups consisting of 12 individuals. Each subgroup will follow the mindfulness courses (led by the same instructor) for 6 weeks. The courses will be delivered every Monday for subgroup 1, Tuesday for subgroup 2, and Wednesday for subgroup 3. Nurses will attend the intervention during working hours as part of the continuing professional education (CPE) courses provided by the Verona Hospital Trust Administration.

BASELINE ASSESSMENT. Before entering the study, participants screening positive will be asked to provide informed consent to participate. Primary outcome will be assessed using the Emotional Exhaustion subscale of the Maslach Burnout Inventory General Survey (MBI-GS). Secondary outcomes will be measured by the Cynicism and Professional Efficacy subscales of the MBI-GS; the Patient Health Questionnaire (PHQ-9); the Generalized Anxiety Disorder (GAD-7); the Insomnia Severity Index (ISI); the Impact of Stressful Events (IES-R); the Perceived Stress Scale (PSS); the Five Facet Mindfulness Questionnaire (FFMQ); and the Forms of Self-Criticising/attacking and Self-Reassuring Scale (FSCRS).

FOLLOW-UP ASSESSMENT. After 1 months from the end of the intervention participants will be re-assessed for Emotional Exhaustion subscale of the Maslach Burnout Inventory General Survey (MBI-GS). Secondary outcomes will be measured by the Cynicism and Professional Efficacy subscales of the MBI-GS; the Patient Health Questionnaire (PHQ-9); the Generalized Anxiety Disorder (GAD-7); the Insomnia Severity Index (ISI); the Impact of Stressful Events (IES-R); the Perceived Stress Scale (PSS); the Five Facet Mindfulness Questionnaire (FFMQ); and the Forms of Self-Criticising/attacking and Self-Reassuring Scale (FSCRS).
