Effectiveness of a structured, framework-based approach to implementation: the Researching Effective Approaches to Cleaning in Hospitals (REACH) Trial

Prevention and control of hospital-acquired infections with multidrug-resistant organism: A review

Multidrug-resistant is defined as nonsusceptibility to at least 1 agent in 3 or more antimicrobial categories. Controlling the spread of drug-resistant organisms is a key step in the management of hospital-acquired infections (HAIs). To review the progress of research on the prevention and control of HAIs with multidrug-resistant organism (MDRO) in the past 5 years, and to provide reference for the development of comprehensive measures for the prevention and control of HAIs with MDRO. We conducted a search in the PUBMED database for studies related to MDRO and HAIs from 2018 to 2023, then integrated this data with information sourced from the U.S.A. The Centers for Disease Control and Prevention. Utilizing information technology to monitor and provide feedback on hand hygiene practices can enhance compliance. Environmental disinfection techniques such as ultraviolet or hydrogen peroxide demonstrate potential in reducing MDRO transmission. While some studies support that contact isolation measures for MDRO-infected or colonized patients can reduce HAIs, others do not confirm this outcome. Approaches for MDRO colonization among patients or physicians may mitigate MDRO transmission risk. Implementing clusterization interventions proves to enhance efficiency and cost-effectiveness in preventing and controlling MDRO. Early screening for pathogen species emerges as a valuable strategy aiding in antimicrobial use control. Combined with evidence from the literature, implementing clusterization interventions that include measures such as monitoring and feedback on hand hygiene and improved environmental disinfection techniques can help prevent and control HAIs with MDRO. However, further clinical studies are needed to validate the optimal clusterization intervention.

Multimodal environmental cleaning strategies to prevent healthcare-associated infections

Infection transmission in healthcare is multifaceted and by in large involves the complex interplay between a pathogen, a host and their environment. To prevent transmission, infection prevention strategies must also consider these complexities and incorporate targeted interventions aimed at all possible transmission pathways. One strategy to prevent and control infection is environmental cleaning. There are many aspects to an environmental cleaning strategy. We believe the key to successfully reducing the risk of healthcare-associated infections through the environment, is to design and implement a multimodal intervention. This paper aims to provide an overview of important considerations for designing a meaningful and sustainable environmental program for healthcare facilities.

Cleaning and disinfecting surfaces in hospitals and long-term care facilities for reducing hospital and facility-acquired bacterial and viral infections: A systematic review

BACKGROUND

Multiply drug-resistant organisms (MDROs) in hospitals and long-term care facilities (LTCFs) of particular concern include meticillin-resistant Staphylococcus aureus (MRSA), vancomycin-resistant enterococcus, multidrug-resistant Acinetobacter species and extended spectrum beta-lactamase producing organisms. Respiratory viruses include influenza and SARS-CoV-2.

AIM

To assess effectiveness of cleaning and disinfecting surfaces in hospitals and LTCFs.

METHODS

CINAHL, Cochrane CENTRAL Register of Controlled Trials, EMBASE, Medline, and Scopus searched inception to 28 June 2021, no language restrictions, for randomized controlled trials, cleaning, disinfection, hospitals, LTCFs. Abstracts and titles were assessed and data abstracted independently by two authors.

FINDINGS

Of fourteen c-RCTs in hospitals and LTCFs, interventions in ten were focused on reducing patient infections of four MDROs and/or healthcare-associated infections (HAIs). In four c-RCTs patient MDRO and/or HAI rates were significantly reduced with cleaning and disinfection strategies including bleach, quaternary ammonium detergents, ultraviolet irradiation, hydrogen peroxide vapour and copper-treated surfaces or fabrics. Of three c-RCTs focused on reducing MRSA rates, one had significant results and one on Clostridioides difficile had no significant results. Heterogeneity of populations, methods, outcomes and data reporting precluded meta-analysis. Overall risk of bias assessment was low but high for allocation concealment, and GRADE assessment was low risk. No study assessed biofilms.

CONCLUSIONS

Ten c-RCTs focused on reducing multiple MDROs and/or HAIs and four had significant reductions. Three c-RCTs reported only patient MRSA colonization rates (one significant reductions), and one focused on Clostridioides difficile (no significant differences). Standardised primary and secondary outcomes are required for future c-RCTs including detailed biofilm cleaning/disinfection interventions.

Environmental hygiene, knowledge and cleaning practice: a phenomenological study of nurses and midwives during COVID-19

Background

Environmental cleanliness is a fundamental tenet in nursing and midwifery but often overshadowed in practice. This study explored nurses’ and midwives’ knowledge and experiences of infection prevention and control (IPC) processes and cleaning, and perceptions about workplace risk-management during COVID-19.

Methods

Six registered and enrolled nurses (one with dual midwife qualifications) were recruited. In-depth telephone interviews were analyzed using Colaizzi's phenomenological method.

Results

Four major themes were identified: Striving towards environmental cleanliness; Knowledge and learning feeds good practice; There's always doubt in the back of your mind; and COVID has cracked it wide open. These articulate the nurses’ and midwives’ experiences and knowledge of IPC, particularly during COVID-19.

Discussion

The findings emphasize the dynamic, interdependent nature of clinical (time, staff knowledge and compliance, work processes, hospital design) and organizational contexts and environmental cleanliness, which must be constantly maintained. COVID-19 opened up critical insights regarding poor past practices and lack of IPC compliance.

Conclusions

COVID-19 has highlighted the criticality of environmental cleanliness within clinical and community settings. Evidence-based, experiential learning is important for nurses and midwives at all career stages, but provides only one solution. Clinician-led hospital design may also reduce the spread of infection; thus, promoting better patient care.

Time for a renewed focus on the role of cleaners in achieving safe health care in low- and middle-income countries

Water, sanitation and hygiene, collectively known as WASH, is an enabler of infection prevention and control (IPC), both of which contribute to safe, quality health care and the prevention of spread of antimicrobial resistance (AMR). This discussion paper considers the importance placed on the role of hygiene, including cleaning and those who clean, in health care facilities, within the context of existing data, guidelines and initiatives. Informed by this, the paper presents five areas for consideration that have the potential to strengthen and further demonstrate the value of this important cadre of staff and their role in clean, safe healthcare, particularly in low- and middle-income countries. The considerations centre around actions to overcome the current data gaps, including the paucity of national data on environmental cleaning and the training of cleaners; strengthening the implementation of norms and standards; combining global and national advocacy efforts; revisiting investment; and addressing research gaps on the issue. The need to act, in line with WHO and UNICEF recommendations to address this overlooked and undercompensated workforce and to elevate their status as important contributors to IPC, WASH and AMR is a pressing one.

Practical recommendations for routine cleaning and disinfection procedures in healthcare institutions: a narrative review

Healthcare-associated infections (HAIs) are the most common adverse outcomes due to delivery of medical care. HAIs increase morbidity and mortality, prolong hospital stay, and are associated with additional healthcare costs. Contaminated surfaces, particularly those that are touched frequently, act as reservoirs for pathogens and contribute towards pathogen transmission. Therefore, healthcare hygiene requires a comprehensive approach whereby different strategies may be implemented together, next to targeted, risk-based approaches, in order to reduce the risk of HAIs for patients. This approach includes hand hygiene in conjunction with environmental cleaning and disinfection of surfaces and clinical equipment. This review focuses on routine environmental cleaning and disinfection including areas with a moderate risk of contamination, such as general wards. As scientific evidence has not yet resulted in universally accepted guidelines nor led to universally accepted practical recommendations pertaining to surface cleaning and disinfection, this review provides expert guidance for healthcare workers in their daily practice. It also covers outbreak situations and suggests practical guidance for clinically relevant pathogens. Key elements of environmental cleaning and disinfection, including a fundamental clinical risk assessment, choice of appropriate disinfectants and cleaning equipment, definitions for standardized cleaning processes and the relevance of structured training, are reviewed in detail with a focus on practical topics and implementation.
