Plain English Summary

Background and study aims
Mental health and wellbeing are among the highest priorities of the public health agenda in the European Union (EU). A large-scale European study of hospital work conditions and associated nurse and patient outcomes revealed high rates of job dissatisfaction and burnout, with burnout rates varying between 10% and 78%. Physician burnout rates ranging from 25% to 60% have been reported, varying across organizations and medical specialties. Magnet4Europe aims to redesign clinical environments in sixty hospitals in five European countries (Belgium, United Kingdom, Germany, Ireland, and Sweden) to promote the mental health and wellbeing of health professionals. Magnet4Europe will implement an evidence-based intervention based on the successful Magnet Recognition Program®, a voluntary hospital designation for nursing care excellence by the American Nurses Credentialing Center. Countless studies have shown that Magnet-recognized hospitals have lower health professional burnout and safer patient care suggesting that the Magnet journey is an intervention that results in positive changes Magnet4Europe seeks to achieve.

Who can participate?
Hospitals with more than 150 beds focused on acute care for adults.
Health professionals working at these hospitals who have direct patient contact and work on inpatient units.

What does the study involve?
In the Magnet4Europe study we will be studying and measuring various items in relation work environment (work relations, job satisfaction, perception of the quality of care and workload) and mental health of health professionals working in acute care hospitals. These items and topics will be measured using standardised and validated questionnaires. The Magnet4Europe study will run for four years and during this period you will be annually invited to take part in a survey. When you decide to take part in the Magnet4Europe study and engage in the survey, you will be asked to register yourself on the Meplis Care Monitor. The Care Monitor will provide access to the survey. You will receive an activation URL, allowing you to register yourself on the Care Monitor. You will receive instructions through the application on how to get started with the questionnaire. You will then be asked a number of questions about your perception of your working environment: the relationship with the doctors, the workload and staffing of the ward, any intention (if any) to leave the profession, patient safety, etc. The questionnaire takes approx. 20 minutes to complete; it should be completed within two weeks of receiving the invitation. You will receive three more invitations after this (i.e. one invitation every following year).

What are the possible benefits and risks of participating?
Benefits: You have no benefit from participating in the Magnet4Europe study and will not be compensated for your participation. However, we hope that your participation in the study will help us to gain more insight on how you perceive hospital care and the demands that are placed on clinical staff. By doing so, you can help to improve the working environment and safety of patient care.
Risks: There are no disadvantages associated with participation. Neither the research team nor the hospital will know whether you have participated in the study or not. A possible refusal to participate in the study will have no adverse effect on your employment at this hospital; nor will your answers have any effect on your participation.

Where is the study run from?
University Hospitals Leuven (Belgium) and recruiting in Belgium, United Kingdom, Sweden, Ireland, Norway, and Germany.

When is the study starting and how long is it expected to run for?
September 2020 to June 2024

Who is funding the study?
European Commission Horizon 2020

ConditionThe impact of organizational redesign of acute care hospitals according to the Magnet© principles of organizational redesign on mental health and wellbeing of health professionals
InterventionA multicenter hospital-based matched pairs usual-practice wait-list cluster randomized controlled trial with a nested mixed-methods process evaluation is used. The order in which hospitals receive the intervention is randomized. Using computer-generated randomization with a 1:1 allocation ratio within each country hospitals will be randomized into an immediate intervention group or a usual-practice wait-list control group. Hospitals allocated to the immediate intervention group, start immediately with the intervention; hospitals in the wait-list group start 12 months later with the intervention. The design of the study inherently makes it impossible to blind hospitals to the intervention.

A multicomponent intervention aimed at organizational redesign of hospitals is applied. Hospitals in the wait-list control group do not access any intervention components until the start of the intervention period in their hospital.

The Magnet4Europe intervention will be launched in the immediate intervention group in month 9 of the project with the first learning collaborative taking place, and will have a total duration of 32 months. The intervention will be initiated in the usual-practice wait-list control group in month 19 and will last for 22 months.

At month 9, hospitals allocated to the immediate intervention group will engage in full exposure to the multi-component intervention. Full exposure entails following active components being operationalised:
1. The hospital start the implementation of the Magnet© components as outlined in the Magnet Manual© of organisational redesign. Using the Magnet4Europe Magnet© Gap Analysis Tool they will perform a gap analysis in close collaboration with their assigned twinning partner. Based on the results of the gap analysis, each intervention hospital is responsible for tailoring and individualizing the interventions to their hospital-specific context and develop a concrete, written implementation plan (in collaboration with the twinning hospital) that will be executed during the course of the intervention period
2. In close relation to element one of the intervention: hospitals engage in an active one-to-one twinning relationship with a Magnet© designated hospital. Twinning entails bi-annual on-site visits of the Magnet© partner to the intervention hospital (or vice-versa) and monthly virtual meetings
3. All hospitals allocated to the immediate intervention group will attend an international Learning collaborative taking place at month 9 (i.e. current plan in protocol)
4. The group of intervention hospitals is actively involved in creating critical mass. They promote innovation, draw public interest and foster replication. Tangibility of critical mass is difficult; nonetheless will it serve catalyst for improvement and enables improvements to take hold and to be more sustainable
5. Provide near real-time feedback to hospitals on clinicians’ reports on work conditions and wellbeing after each of the quantitative data collection periods using rapid document delivery via SAS Output Delivery System. The duration of exposure in the immediate intervention group is 32 months

The intervention in the usual-practice waitlist control group is employed 10 months later compared to the immediate intervention group and is - to a large extent - identical. At month 19 these hospitals engage in full exposure to the different intervention components. The only minor difference can be found in component three: i.e. the usual-practice waitlist hospitals now have access to implementation strategies of hospitals in the immediate intervention group allowing for expeditated implementation of the Magnet© principles. This knowledge is not available for the immediate intervention group. The usual-practice waitlist control group will receive feedback on clinicians’ reports on work conditions and wellbeing for the first time. The duration of exposure in usual-practice waitlist control group is 22 months

Publication and dissemination planMagnet4Europe has a strong focus on strengthening the evidence on the impact of work environment on mental health of health professionals. Findings will be published in peer reviewed journals and through other channels designed to reach a diverse community of researchers, practitioners, and other stakeholders. Gold open access will be used for the key findings of the study to ensure maximum exposure to a practice community. Beyond the funded life of the project the aim is to maximize accessibility by fully exploiting the opportunity for green open access and, where possible, identifying additional funds to support further gold open access. The study protocol is the first publication aimed for in this project.
IPD sharing planThe datasets generated during and/or analysed during the current study are available from the corresponding author on reasonable request.
