Background and study aims
Antibiotic resistance is one of the foremost concerns of modern medicine. While antibiotics have saved countless lives, emerging resistant bacteria (for which many antibiotics do not work) are endangering the well-being of future generations. We need to take action to reduce the effects of these infections. The EU-funded REVERSE project will develop a framework to help prevent, manage, and limit the impact of drug-resistant bacteria. The project will use expertise from many different disciplines in a combined action plan for hospitals. This will also help to develop new strategies to fight resistant bacteria and reduce their effect on health and the European economy.

Who can participate?
Adult inpatients in intensive care, internal medicine, haematology-oncology, and surgery (including transplant units) at hospitals in four European countries with high rates of infections caused by resistant bacteria.

What does the study involve?
Three programmes will be started one after the other to try and reduce these infections. All hospitals will start the programmes but at different times. Some of the hospitals will also have additional help to make sure these programmes are put in place. Some of the data collected include hospital antibiotic use, hand sanitizer use, and hospital infection numbers. The researchers will also do a cost analysis to look at whether these programmes saved money by preventing infections. For this, some patients in the hospital will be asked questions about their quality of life after they leave the hospital.

What are the possible benefits and risks of participating?
There is no additional risk to patients beyond that of a regular hospital admission. The potential benefits to patients include reduced rates of infection with resistant bacteria.

Where is the study run from?
University of Zurich (Switzerland)

When is the study starting and how long is it expected to run for?
July 2021 to June 2026

Study objectivesRationale: Develop and implement cost-effective strategies and tools for the prevention and clinical management of healthcare-associated infections due to multidrug-resistant pathogens, and to reduce the burden of antimicrobial resistance in high prevalence care settings.
Ethics approval(s)Approved 07/01/2022, Kantonale Ethikkommission (Stampfenbachstrasse 121, 8090 Zürich, Switzerland; +41 (0)43 259 79 70; info.kek@kek.zh.ch), ref: AO-2021-00078

InterventionThree bundled programmes will be sequentially implemented after a minimum 6-month baseline monitoring period - microbiology and diagnostic stewardship (MDS), infection prevention and control (IPC), and antimicrobial stewardship (ABS). These interventions target the institutions and health professionals. The data will be collected throughout the baseline and intervention periods. The details of the MDS, IPC, and ABS interventions are as follows (please note: not all interventions within a programme will start immediately):

MDS:
1. Guidance document on the usage of diagnostics for suspected bacterial infection
2. Audit and feedback on compliance to guidance
3. Universal screening in high-risk settings and abdominal surgery patients (intensive care, haemato-oncology, transplant units);
4. Molecular characterization of blood cultures and samples from lower respiratory tracts (HAP) to inform ABS
5. Rapid tests if molecular tests are unavailable (e.g. CARBA-5 or beta-LACTA)
6. Molecular characterization of isolated CRE from repetitive colonisation surveys to inform IPC.

IPC:
1. Enhanced standard precautions (e.g., use of gloves for contacts with wounds and body fluids) and hand hygiene, with special emphasis on the use of alcohol-based hand rub (ABHR)
2. Regular point prevalence surveys to detect previously unknown multidrug-resistant organism (MDRO) carriers and identify hidden hot spots of MDRO transmission in the concerned institution in collaboration with WP2MDS
3. Reinforced basic environmental hygiene
4. Targeted MDRO screening at admission for selected high-risk populations (e.g., previously known MDRO carriers)
5. Audits and feedback on the basic IPC components in regular time intervals
6. Enhanced, universal MDRO screening at admission in ICUs and other high-risk units
7. Reinforced contact precautions for identified MDRO carriers
8. Enhanced cleaning in high-risk settings with point prevalence sampling surveys
9. Improved information transfer on MDRO's carriage status within the hospital and along the referral pathways
10. Root-cause analysis of newly detected cases to direct infection control measures
11. Setup and implementation of advanced cohorting facilities for selected highly resistant MDROs (e.g., CRE)
12. Dedicating nursing staff for patient care with highly resistant MDROs
13. Decolonization or decontamination of colonized patients or patients in high-risk units using chlorhexidine body wash
14. Molecular analysis and sequencing of isolates for outbreak investigation (please see 3.4.4 for details)
15. The organisational and pharmaceutical interventions will be started with the basic best practices bundle.

ABS:
1. Establishment of a multidisciplinary stewardship committee
2. Guidance document on syndrome-specific treatment pathways
3. Dedicated recommendations for new drugs
4. Training on judicious antibiotic prescription
5. Audit and feedback on compliance to guidance on antibiotic use
6. Stewardship rounds two times a week in high-risk settings (intensive care, haematology-oncology, transplant units)
7. Pathways for integration of antibiotic consumption reporting to the stewardship policies
8. Weekly stewardship rounds in wards other than high-risk, but with a high prevalence of AMR
9. Integration of screening results in the decision-making process for empiric therapy for severe bacterial infections in immunocompromised patients
10. Integration of screening results before abdominal surgery for personalised prophylaxis
11. Integration of molecular characterization of cultures to drive targeted therapy of bloodstream infections and hospital-acquired pneumonia

All centres will have a point prevalence survey for CRE colonization at three predefined time points. Positive swabs may be sequenced to assess for clonality and to establish transmission links. At two timepoints in the study, an audit will be done to assess microbiology capabilities.

In addition, before the IPC module, hospitals will be randomised to either basic implementation support (12 BASIC study sites) or enhanced implementation support (12 ENHANCE study sites) as part of the hybrid approach. This randomisation applies only to the implementation part of this study. The hospitals will be stratified by country and cluster-randomized in a stepped wedge design.

A cost-effectiveness analysis will be done at the end to assess the feasibility of expanding such an initiative. Part of this cost-effectiveness analysis includes a cohort study comparing the quality of life post-discharge of patients with hospital-acquired multi-drug resistant infections to patients without such infections. The cohort study will use validated questionnaires at baseline, 1, 3, 6, and 12 months post-discharge. There will be detailed costing data obtained from the hospitals to accurately estimate the investment required to sustain these initiatives.

IPD sharing planThe following applies to persons outside of the REVERSE consortium. The data will be available after publication. The project email can be used to contact the coordinating team regarding data requests (reverse@usz.ch). Data will be made available where possible to support further research under FAIR principles, except for data that are confidential or cannot be shared under the GDPR regulations. De-identified hospital-level data (e.g.: data on hospital-acquired infection rates, antimicrobial use, ABHR use, or cost data) needed to verify the results will be available for approximately 5 years after the project ends. De-identified and aggregate data from the cohort study needed to verify results will also be available for approximately 5 years after the project ends. Please note, participant-level data from the cohort study will not be available due to patient-level confidential information. The researchers will share data electronically with other research groups conducting meta-analyses or reviews on IPC, ABS, or MDS interventions. This adheres to the data-sharing rules outlined in the Grant Agreement with the European Commission.
