Scenario-based simulation training for the WHO hand hygiene self-assessment framework

The WHO SAVE LIVES: Clean Your Hands global hand hygiene campaign, launched in 2009 and celebrated annually on the 5th of May, features specific calls to action seeking to increase engagement from stakeholders’ collaborations in hand hygiene improvement. WHO calls on everyone to be inspired by the global movement towards universal health coverage (UHC). Infection prevention and control (IPC), including hand hygiene, is critical to achieve UHC as it has a direct impact on quality of care and patient safety across all levels of the health services. In the framework of UHC, the theme for 5 May 2019 is “Clean care for all – it’s in your hands”. In this context, the WHO has launched a global survey to assess the current level of progress of IPC programmes and hand hygiene activities in healthcare facilities (HCFs) worldwide. This involved the creation of two tools for healthcare facilities: the WHO Infection Prevention and Control Assessment Framework (IPCAF) and the WHO Hand Hygiene Self-Assessment Framework (HHSAF). The objective of this paper is to provide case scenario-based simulation for IPC specialists to simulate and fully assimilate the correct completion of the HHSAF framework in a standardized format. The three case scenarios have been tested and are proposed for the reader to assess the HHSAF of different HCFs in a variety of contexts, even in low-resouce settings. They were designed for simulation training purposes to achieve standardization and interactive learning. These scenarios are meant to be used by professionals in charge of implementing a hand hygiene improvement strategy within their HCF, as well as for simulation and standardized training purposes prior to completing and submitting data for the 2019 WHO Global Survey. Additionally, information provided by the use of the HHSAF can easily be translated into action plans to support the implementation and improvement related to specific indicators of hand hygiene promotion. We invite all HCFs to participate in the 2019 WHO global survey and monitor the level of progress of their IPC programme and hand hygiene activities.

Implementation of infection prevention and control in acute care hospitals in Mainland China - a systematic review

Background

Healthcare-associated infections (HAIs) and antimicrobial resistance (AMR) affect patients in acute-care hospitals worldwide. No systematic review has been published on adoption and implementation of the infection prevention and control (IPC) key components. The objective of this systematic review was to assess adoption and implementation of the three areas issued by the “National Health Commission of the People’s Republic of China” in acute-care hospitals in Mainland China, and to compare the findings with the key and core components on effective IPC, issued by the European Centre for Disease Prevention and Control (ECDC) and the World Health Organization (WHO).

Methods

We searched PubMed and the Chinese National Knowledge Infrastructure for reports on the areas “structure, organisation and management of IPC”, “education and training in IPC”, and “surveillance of outcome and process indicators in IPC” in acute-care facilities in Mainland China, published between January 2012 and October 2017. Results were stratified into primary care hospitals and secondary/tertiary care hospitals.

Results

A total of 6580 publications were retrieved, of which 56 were eligible for final analysis. Most of them were survey reports (n = 27), followed by observational studies (n = 17), and interventional studies (n = 12), either on hand hygiene promotion and best practice interventions (n = 7), or by applying education and training programmes (n = 5). More elements on IPC were reported by secondary/tertiary care hospitals than by primary care hospitals. Gaps were identified in the lack of detailing on organisation and management of IPC, education and training activities, and targets of surveillance such as central line-associated bloodstream infections, ventilator associated pneumonia, catheter-associated urinary tract infections, and Clostridium difficile infections. Information was available on adoption and implementation of 7 out of the 10 ECDC key components, and 7 out of the 8 WHO core components.

Conclusion

To variable degrees, there is evidence on implementation of all NHCPRC areas and of most of the ECDC key components and the WHO core components in acute care hospitals in Mainland China. The results are encouraging, but gaps in effective IPC were identified that may be used to guide future national policy-making in Mainland China.

Impact of participation in a surgical site infection surveillance network: results from a large international cohort study

BACKGROUND

Surveillance of surgical site infections (SSIs) is a core component of effective infection control practices, though its impact has not been quantified on a large scale.

AIM

To determine the time-trend of SSI rates in surveillance networks.

METHODS

SSI surveillance networks provided procedure-specific data on numbers of SSIs and operations, stratified by hospitals' year of participation in the surveillance, to capture length of participation as an exposure. Pooled and procedure-specific random-effects Poisson regression was performed to obtain yearly rate ratios (RRs) with 95% confidence intervals (CIs), and including surveillance network as random intercept.

FINDINGS

Of 36 invited networks, 17 networks from 15 high-income countries across Asia, Australia and Europe participated in the study. Aggregated data on 17 surgical procedures (cardiovascular, digestive, gynaecological-obstetrical, neurosurgical, and orthopaedic) were collected, resulting in data concerning 5,831,737 operations and 113,166 SSIs. There was a significant decrease in overall SSI rates over surveillance time, resulting in a 35% reduction at the ninth (final) included year of surveillance (RR: 0.65; 95% CI: 0.63-0.67). There were large variations across procedure-specific trends, but strong consistent decreases were observed for colorectal surgery, herniorrhaphy, caesarean section, hip prosthesis, and knee prosthesis.

CONCLUSION

In this large, international cohort study, pooled SSI rates were associated with a stable and sustainable decrease after joining an SSI surveillance network; a causal relationship is possible, although unproven. There was heterogeneity in procedure-specific trends. These findings support the pivotal role of surveillance in reducing infection rates and call for widespread implementation of hospital-based SSI surveillance in high-income countries.

Keeping hospitals clean and safe without breaking the bank; summary of the Healthcare Cleaning Forum 2018

Keeping hospitals clean is a crucial patient safety issue. The importance of the hospital environment in patient care has only recently been recognized widely in infection prevention and control (IPC). In order to create a movement for change, a group of international infection control experts teamed up with Interclean, the largest cleaning trade-show in the world to create the Healthcare Cleaning Forum. This paper is the result of this conference, which featured leaders in healthcare environmental science from across Europe.

Although the available literature is limited, there is now enough evidence to demonstrate that maintaining the hygiene of the hospital environment helps prevent infections. Still, good interventional studies are rare, the quality of products and methods available is heterogeneous, and environmental hygiene personnel is often relatively untrained, unmotivated, under-paid, and under-appreciated by other actors in the hospital. Coupled with understaffed environmental hygiene service departments, this creates lasting issues in regards to patient and healthcare worker safety.

The Healthcare Cleaning Forum was designed as a platform for healthcare experts, cleaning experts, hospital managers and industry to meet productively. The conference aimed to summarize the state-of-the-art knowledge in the field, create awareness and dialogue, challenge dogma and begin to shape a research agenda for developing the field of hospital hygiene and environmental control. Hospital environmental hygiene is far more complex than other types of cleaning; further evidence-based research in the field is needed. It involves the integration of current and new technologies with human elements that must work together synergistically to achieve optimal results. The education, training and career development, behavior, and work organization of environmental hygiene personnel are at the core of the proposals for the creation of a global initiative. Ultimately, what is needed is a reevaluation of how hospitals view environmental hygiene: not just as an area from which to cut costs, but one that can add value. Hospitals and key stakeholders must work together to change how we maintain the hospital environment in order to better protect patients.

Antibacterial efficacy of handrubbing for 15 versus 30 seconds: EN 1500-based randomized experimental study with different loads of Staphylococcus aureus and Escherichia coli

OBJECTIVES

Compliance with the World Health Organization 'how to handrub' action is suboptimal. Simplifying the hand-hygiene action may improve practice. However, it is crucial to preserve antibacterial efficacy. We tested the non-inferiority of 15 versus 30 seconds handrubbing for Staphylococcus aureus and Escherichia coli contamination at different loads, using hand-size customized alcohol-based handrub (ABHR) volumes.

METHODS

In an EN1500-based study, 18 health-care workers (HCWs) with extensive experience in hand hygiene rubbed hands with a hand-size customized volume of isopropanol 60% v/v. They repeated the following sequence: hand contamination (E. coli or S. aureus; broth containing 10⁸ or 10⁶ CFU/mL); baseline fingertips sampling; handrubbing (15 or 30 seconds); re-sampling. The main outcome was log₁₀ CFU corrected reduction factor (cRF) on HCWs' hands, applying a generalized linear mixed model with a random intercept for subject.

RESULTS

The median cRF was 2.1 log₁₀ (interquartile range 1.50-3.10). After fitting the model, cRF was significantly higher for S. aureus compared with E. coli but there was no significant effect for duration of handrubbing or contamination fluid concentration. Fifteen seconds of handrubbing was non-inferior to 30 (-0.06 log₁₀, 95% CI -0.34 to 0.22; EN1500 0.60 log₁₀ non-inferiority margin). This was confirmed in all pre-specified subgroups.

CONCLUSION

Among experienced HCWs using a hand-size customized volume of ABHR, handrubbing for 15 seconds was non-inferior to 30 seconds in reducing bacterial load, irrespective of type of bacteria or contamination fluid concentration. This provides further support for a shorter, 15-seconds, hand-hygiene action.

Migrant and refugee populations: a public health and policy perspective on a continuing global crisis

The 2015-2017 global migratory crisis saw unprecedented numbers of people on the move and tremendous diversity in terms of age, gender and medical requirements. This article focuses on key emerging public health issues around migrant populations and their interactions with host populations. Basic needs and rights of migrants and refugees are not always respected in regard to article 25 of the Universal Declaration of Human Rights and article 23 of the Refugee Convention. These are populations with varying degrees of vulnerability and needs in terms of protection, security, rights, and access to healthcare. Their health status, initially conditioned by the situation at the point of origin, is often jeopardised by adverse conditions along migratory paths and in intermediate and final destination countries. Due to their condition, forcibly displaced migrants and refugees face a triple burden of non-communicable diseases, infectious diseases, and mental health issues. There are specific challenges regarding chronic infectious and neglected tropical diseases, for which awareness in host countries is imperative. Health risks in terms of susceptibility to, and dissemination of, infectious diseases are not unidirectional. The response, including the humanitarian effort, whose aim is to guarantee access to basic needs (food, water and sanitation, healthcare), is gripped with numerous challenges. Evaluation of current policy shows insufficiency regarding the provision of basic needs to migrant populations, even in the countries that do the most. Governments around the world need to rise to the occasion and adopt policies that guarantee universal health coverage, for migrants and refugees, as well as host populations, in accordance with the UN Sustainable Development Goals. An expert consultation was carried out in the form of a pre-conference workshop during the 4th International Conference on Prevention and Infection Control (ICPIC) in Geneva, Switzerland, on 20 June 2017, the United Nations World Refugee Day.

Hand hygiene in hospitals: anatomy of a revolution

Healthcare-associated infections (HAIs) affect hundreds of millions of individuals worldwide. Performing hand hygiene is widely accepted as a key strategy of infection prevention and control (IPC) to prevent HAIs, as healthcare workers' contaminated hands are the vehicle most often implicated in the cross-transmission of pathogens in health care. Over the last 20 years, a paradigm shift has occurred in hand hygiene: the change from handwashing with soap and water to using alcohol-based hand rubs. In order to put this revolution into context and understand how such a change was able to be implemented across so many different cultures and geographic regions, it is useful to understand how the idea of hygiene in general, and hand hygiene specifically, developed. This paper aims to examine how ideas about hygiene and hand hygiene evolved from ancient to modern times, from a ubiquitous but local set of ideas to a global phenomenon. It reviews historical landmarks from the first known documented recipe for soap by the Babylon civilization to the discovery of chlorine, and significant contributions by pioneers such as Antoine Germain Labarraque, Alexander Gordon, Oliver Wendell Holmes, Ignaz Philip Semmelweis, Louis Pasteur and Joseph Lister. It recalls that handwashing with soap and water appeared in guidelines to prevent HAIs in the 1980s; describes why alcohol-based hand rub replaced this as the central tool for action within a multi-modal improvement strategy; and looks at how the World Health Organization and other committed stakeholders, governments and dedicated IPC staff are championing hand hygiene globally.

Conflicts of interest in infection prevention and control research: no smoke without fire. A narrative review

Conflicts of interest (COIs) do occur in healthcare research, yet their impact on research in the field of infection prevention and control (IPC) is unknown. We conducted a narrative review aiming to identify examples of COIs in IPC research. In addition to well-known instances, we conducted PubMed and Google searches to identify and report case studies of COIs in IPC and antimicrobial resistance (AMR), which were chosen arbitrarily following consensus meetings, to illustrate different types of COIs. We also searched the Retraction Watch database and blog to systematically identify retracted IPC and/or infectious disease-related papers. Our review highlights COIs in academic research linked to ties between industry and physicians, journal editors, peer-reviewed journals' choice for publication, and guideline committees participants and authors. It explores how COIs can affect research and could be managed. We also present several selected case studies that involve (1) the chlorhexidine industry and how it has used marketing trials and key opinion leaders to promote off-label use of its products; (2) the copper industry and how reporting of its trials in IPC have furthered their agenda; (3) the influence of a company developing "closed infusion systems" for catheters and how this affects networks in low- and middle-income countries and guideline development; (4) potential perverse incentives hospitals may have in reporting healthcare-associated infection or AMR rates and how government intervention may restrict AMR research for fear of bad publicity and subsequent negative economic consequences. Finally, the analysis of reasons for the retraction of previously published papers highlights the fact that misconduct in research may have other motivations than financial gain, the most visible form of COIs. COIs occur in the field of research in general, and IPC and AMR are no exceptions. Their effects pervade all aspects of the research and publication processes. We believe that, in addition to improvements in management strategies of COIs, increased public funding should be available to decrease researchers' dependency on industry ties. Further research is needed on COIs and their management.

Global hand hygiene improvement progress: two surveys using the WHO Hand Hygiene Self-Assessment Framework

The World Health Organization (WHO) conducted two global surveys in 2011 and 2015 using the Hand Hygiene Self-Assessment Framework. In 2011, 2119 health facilities from 69 countries participated, and in 2015, 807 health facilities from 91 countries participated. In total, 86 facilities submitted results for both surveys; their overall score increased significantly (P<0.001) from 335.1 [standard deviation (SD) 7.5] to 374.4 (SD 90.5). In terms of WHO regions, the scores for the Eastern Mediterranean, Europe and Western Pacific regions all improved significantly (P<0.01). This represents a snapshot of the current position of global hand hygiene improvement efforts, outlining facility progress and highlighting the value of such an assessment tool.

Implementing infection prevention practices across European hospitals: an in-depth qualitative assessment

Objective

The Prevention of Hospital Infections by Intervention and Training (PROHIBIT) project included a cluster-randomised, stepped wedge, controlled study to evaluate multiple strategies to prevent catheter-related bloodstream infection. We report an in-depth investigation of the main barriers, facilitators and contextual factors relevant to successfully implementing these strategies in European acute care hospitals.

Methods

Qualitative comparative case study in 6 of the 14 European PROHIBIT hospitals. Data were collected through interviews with key stakeholders and ethnographic observations conducted during 2-day site visits, before and 1 year into the PROHIBIT intervention. Qualitative measures of implementation success included intervention fidelity, adaptation to local context and satisfaction with the intervention programme.

Results

Three meta-themes emerged related to implementation success: ‘implementation agendas’, ‘resources’ and ‘boundary-spanning’. Hospitals established unique implementation agendas that, while not always aligned with the project goals, shaped subsequent actions. Successful implementation required having sufficient human and material resources and dedicated change agents who helped make the intervention an institutional priority. The salary provided for a dedicated study nurse was a key facilitator. Personal commitment of influential individuals and boundary spanners helped overcome resource restrictions and intrainstitutional segregation.

Conclusion

This qualitative study revealed patterns across cases that were associated with successful implementation. Consideration of the intervention–context relation was indispensable to understanding the observed outcomes.

Native septic arthritis is not an immediate surgical emergency

Acute native joint septic arthritis is generally considered a surgical emergency, requiring drainage within hours, including during night, weekend or holiday shifts. However, there are few data supporting the need for the disruption caused by this degree of urgency.

METHODS

We performed a retrospective review of all adult patients seen in our medical center from 1997-2015 with culture-proven septic arthritis and noted the epidemiology of sequelae, and their possible association with a delay in surgical drainage.

RESULTS

Of 204 septic arthritis episodes, 46 (23%) involved interdigital hand and foot joints. Large joints involved included the knee (n = 67), shoulder (48), hip (22), ankle (8), acromio-clavicular (5), elbow (4), wrist (3), and sterno-clavicular (1) regions. All patients underwent surgical drainage of the joint and received targeted systemic antibiotic therapy. Sequelae of varying severity occurred in 83 patients (41%): recurrences (n = 15); secondary arthrosis (30); persistent pain (9); Girdlestone procedure (9); arthrodesis (9); amputation (8); stiffness (8); and Chronic Regional Pain Syndrome (2). By multivariate Cox regression analysis factors did not predict sequelae included: age; treatment with systemic corticosteroids; pre-existing clinical or radiological arthropathy; total duration of antibiotic therapy; type of joint; and, number of surgical interventions. Similarly, there was no association of sequelae with the number of days of pre-hospitalization joint symptoms (hazard ratio 1.0, 95% confidence interval 0.99-1.01) or hours spent in the emergency department (HR 1.0, 0.9-1.2). Notably, patients who had joint lavage within 6 h of presentation had similar functional outcomes as those with lavage done at 6-12 h, 12-24 h, or > 24 h after presentation.

CONCLUSIONS

Our data suggest that for native septic arthritis, in the absence of clinical sepsis immediate joint drainage does not appear to reduce the risk of sequelae compared with delayed drainage.

Point prevalence of healthcare-associated infections and antibiotic use in three large Swiss acute-care hospitals

BACKGROUND

The overall burden of healthcare-associated infections (HAIs) remains high, even in high-income countries. However, the current burden of HAI in Switzerland is unknown. Prevalence surveys have a long tradition in the field of infection prevention and control for measuring both HAI and antimicrobial use. The objective of this survey was to test the point prevalence survey (PPS) methodology of the European Centre for Disease Prevention and Control (ECDC) in acute-care hospitals in Switzerland.

METHODS

Two tertiary care hospitals and one secondary care hospital in central and western Switzerland participated in the survey. Patients from all wards except for emergency departments and psychiatric wards were included. Data were collected on a single day for every ward with a maximum time frame of 2 weeks for completing data collection. Methodology and definitions were based on the most recent ECDC PPS protocol.

RESULTS

Data on a total of 2421 patients were analysed. One hundred thirty-six patients had 153 HAIs, corresponding to a prevalence of 5.6% (95% confidence interval [CI] 4.7-6.5%). Rapidly fatal McCabe score, hospitalisation in the intensive care unit (ICU), and having a medical device in place were independent risk factors for HAI. Lower respiratory tract infection was the most frequent HAI type (24.8%), followed by surgical site infection (22.2%), bloodstream infection (17.0%) and urinary tract infection (13.7%). The highest HAI prevalence (26.2%) was observed in the ICU. In total, 60.8% of all HAIs were microbiologically confirmed. The most common microorganism was Escherichia coli (21.1%). Six hundred sixty-nine patients (27.6%, 95% CI 25.9-29.4%) received 893 antimicrobials for 705 indications. Community-acquired infections (39.0%) were the most common indication for antimicrobial use and amoxicillin-clavulanate was the most commonly prescribed antimicrobial (18.4%).

CONCLUSIONS

HAI prevalence and antimicrobial use in this survey were similar to findings of the past ECDC PPS. The ECDC methodology proved applicable to Swiss acute-care hospitals.
