Train-the-Trainers in hand hygiene facilitate the implementation of the WHO hand hygiene multimodal improvement strategy in Japan: evidence for the role of local trainers, adaptation, and sustainability

BACKGROUND

"Train-the-Trainers in hand hygiene" (TTT) is a standardized training to train infection prevention and control (IPC) practitioners with the aim to promote hand hygiene in health care according to the World Health Organization (WHO) multimodal improvement strategy. Little is known in the literature about the sustained impact of hand hygiene and IPC trainings adapted locally. The aim of this study is to describe the impact of three TTT courses conducted annually in Japan on the adoption of the WHO multimodal improvement strategy by local IPC practitioners who became a "trainer" after their first TTT participation as a "trainee".

METHODS

Three TTT courses were conducted annually from 2020 to 2022 in Japan. A team "TTT-Japan" composed of more than 20 IPC practitioners who completed their first TTT participation adapted the original TTT program to reflect the local healthcare context in Japan, and subsequently convened the 2nd and 3rd TTTs. Pre- and post-course evaluations and post-course satisfaction surveys of the course participants were conducted to assess improvement in knowledge on hand hygiene and perception towards the course, respectively. Attitude and practice surveys of the TTT-Japan trainers were conducted to assess their perception and experience in hand hygiene promotion. The Hand Hygiene Self-Assessment Framework (HHSAF), a validated tool created by WHO to monitor the capacity of hand hygiene promotion at facility level, was applied at TTT-Japan trainers' facilities to compare results before and after trainers' engagement. We applied inductive thematic analysis for qualitative analyses of open-ended survey questions of the trainers' attitude and practice surveys, and the Wilcoxon Sign Rank test for quantitive comparisons of pre- and post-data for the surveys and HHSAF.

RESULTS

158 Japanese healthcare workers participated in three TTT courses, the majority of whom (131, 82.9%) were nurses. Twenty-seven local trainers were involved in 2nd and 3rd TTTs. The scores of pre- and post-course evaluations significantly improved after the course (P < 0.001) and the improvement was consistent across all three TTTs. Post-course satisfaction survey showed that over 90% of the participants reported that the course met their expectations and that what they learned in the courses would be useful for their practice. Trainers' attitude and practice survey showed that more than three quarters (76.9%) of the trainers reported that their experience as a trainer had a positive impact on their practice at their own facilities. Qualitative analysis of the trainers' attitude and practice survey revealed that trainers appreciated continuous learning as a trainer, and group effort to promote hand hygiene as the TTT-Japan team. The HHSAF institutional climate change element at the trainers' facilities significantly improved after their engagement as a trainer (P = 0.012).

CONCLUSIONS

TTTs were successfully adapted and implemented in Japan, leading to sustained hand hygiene promotion activities by local trainers over three years. Further research is warranted to assess the long-term impact on local hand hygiene promotion in different settings.

Long term anti-SARS-CoV-2 antibody kinetics and correlate of protection against Omicron BA.1/BA.2 infection

Binding antibody levels against SARS-CoV-2 have shown to be correlates of protection against infection with pre-Omicron lineages. This has been challenged by the emergence of immune-evasive variants, notably the Omicron sublineages, in an evolving immune landscape with high levels of cumulative incidence and vaccination coverage. This in turn limits the use of widely available commercial high-throughput methods to quantify binding antibodies as a tool to monitor protection at the population-level. Here we show that anti-Spike RBD antibody levels, as quantified by the immunoassay used in this study, are an indirect correlate of protection against Omicron BA.1/BA.2 for individuals previously infected by SARS-CoV-2. Leveraging repeated serological measurements between April 2020 and December 2021 on 1083 participants of a population-based cohort in Geneva, Switzerland, and using antibody kinetic modeling, we found up to a three-fold reduction in the hazard of having a documented positive SARS-CoV-2 infection during the Omicron BA.1/BA.2 wave for anti-S antibody levels above 800 IU/mL (HR 0.30, 95% CI 0.22-0.41). However, we did not detect a reduction in hazard among uninfected participants. These results provide reassuring insights into the continued interpretation of SARS-CoV-2 binding antibody measurements as an independent marker of protection at both the individual and population levels.

New frontiers in healthcare environmental hygiene: thoughts from the 2022 healthcare cleaning forum

Healthcare environmental hygiene (HEH) has become recognized as being increasingly important for patient safety and the prevention of healthcare-associated infections. At the 2022 Healthcare Cleaning Forum at Interclean in Amsterdam, the academic lectures focused on a series of main areas of interest. These areas are indicative of some of the main trends and avenues for research in the coming years. Both industry and academia need to take steps to continue the momentum of HEH as we transition out of the acute phase of the Covid-19 pandemic. There is a need for new ways to facilitate collaboration between the academic and private sectors. The Clean Hospitals® network was presented in the context of the need for both cross-disciplinarity and evidence-based interventions in HEH. Governmental bodies have also become more involved in the field, and both the German DIN 13603 standard and the UK NHS Cleaning Standards were analyzed and compared. The challenge of environmental pathogens was explored through the example of how P. aeruginosa persists in the healthcare environment. New innovations in HEH were presented, from digitalization to tracking, and automated disinfection to antimicrobial surfaces. The need for sustainability in HEH was also explored, focusing on the burden of waste, the need for a circular economy, and trends towards increasingly local provision of goods and services. The continued focus on and expansion of these areas of HEH will result in safer patient care and contribute to better health systems.

Prevalence and predictors of psychological distress before, during, and after a COVID-19 pandemic wave in Switzerland, 2021

There are concerns about acute and long-term mental health effects of the COVID-19 pandemic. This study examined the prevalence and predictors of psychological distress before, during, and after a pandemic wave in Switzerland, 2021. Prevalence of psychological distress was estimated in adults aged 35-96 years using the General Health Questionnaire-12 administered in June 2021 (Specchio-COVID19 cohort, N = 3965), and compared to values from 2003 to 2006 (CoLaus|PsyCoLaus cohort, N = 5667). Anxiety and depression were assessed from February to June 2021 using the Generalised Anxiety Disorder scale-2 and the Patient Health Questionnaire-2, respectively. Prevalence of psychological distress in June 2021, after the pandemic wave (16.0% [95% CI, 14.6%-17.4%]) was comparable to pre-pandemic levels (15.1% [14.0%-16.2%]). Anxiety and depression were highest at the start of the pandemic wave in February 2021, and declined from February to June with the relaxation of measures. Predictors of psychological distress included being younger, female, a single parent, unemployed, a change in working hours or job loss in the past 6 months, greater perceived severity and contagiousness of COVID-19, and self-reported post COVID-19. By June 2021, following a pandemic wave, prevalence of psychological distress in Switzerland was closer to pre-pandemic levels. These findings highlight the need for additional mental health support during times of stricter government policies relating to COVID-19; yet they also suggest that individuals can adapt relatively quickly to the changing context.

Seroprevalence of anti-SARS-CoV-2 antibodies and cross-variant neutralization capacity after the Omicron BA.2 wave in Geneva, Switzerland: a population-based study

Background

More than two years into the COVID-19 pandemic, most of the population has developed anti-SARS-CoV-2 antibodies from infection and/or vaccination. However, public health decision-making is hindered by the lack of up-to-date and precise characterization of the immune landscape in the population. Here, we estimated anti-SARS-CoV-2 antibodies seroprevalence and cross-variant neutralization capacity after Omicron became dominant in Geneva, Switzerland.

Methods

We conducted a population-based serosurvey between April 29 and June 9, 2022, recruiting children and adults of all ages from age-stratified random samples of the general population of Geneva, Switzerland. We tested for anti-SARS-CoV-2 antibodies using commercial immunoassays targeting either the spike (S) or nucleocapsid (N) protein, and for antibody neutralization capacity against different SARS-CoV-2 variants using a cell-free Spike trimer-ACE2 binding-based surrogate neutralization assay. We estimated seroprevalence and neutralization capacity using a Bayesian modeling framework accounting for the demographics, vaccination, and infection statuses of the Geneva population.

Findings

Among the 2521 individuals included in the analysis, the estimated total antibodies seroprevalence was 93.8% (95% CrI 93.1-94.5), including 72.4% (70.0-74.7) for infection-induced antibodies. Estimates of neutralizing antibodies in a representative subsample (N = 1160) ranged from 79.5% (77.1-81.8) against the Alpha variant to 46.7% (43.0-50.4) against the Omicron BA.4/BA.5 subvariants. Despite having high seroprevalence of infection-induced antibodies (76.7% [69.7-83.0] for ages 0-5 years, 90.5% [86.5-94.1] for ages 6-11 years), children aged <12 years had substantially lower neutralizing activity than older participants, particularly against Omicron subvariants. Overall, vaccination was associated with higher neutralizing activity against pre-Omicron variants. Vaccine booster alongside recent infection was associated with higher neutralizing activity against Omicron subvariants.

Interpretation

While most of the Geneva population has developed anti-SARS-CoV-2 antibodies through vaccination and/or infection, less than half has neutralizing activity against the currently circulating Omicron BA.5 subvariant. Hybrid immunity obtained through booster vaccination and infection confers the greatest neutralization capacity, including against Omicron.

Acceptability of an alcohol-based handrub gel with superfatting agents among healthcare workers: a randomized crossover controlled study

Introduction

Healthcare workers often experience skin dryness and irritation from performing hand hygiene frequently. Low acceptability and tolerability of a formulation are barriers to hand hygiene compliance, though little research has been conducted on what specific types of formulation have higher acceptability than others.

Objective

To compare the acceptability and tolerability of an ethanol-based handrub gel with superfatting agents to the isopropanol-based formulations (a rub and a gel formulation) currently used by healthcare workers at the University of Geneva Hospitals, Geneva, Switzerland.

Methods

Forty-two participants were randomized to two sequences, testing the isopropanol-based formulation that they are using currently (Hopirub® or Hopigel®), and the ethanol-based formulation containing superfatting agents (Saniswiss Sanitizer Hands H1). Participants tested each of the formulations over 7–10 day work shifts, after which skin condition was assessed and feedback was collected.

Results

H1 scored significantly better than the control formulations for skin dryness (P = 0.0209), and participants felt less discomfort in their hands when using that formulation (P = 0.0448). H1 caused less skin dryness than Hopirub®/Hopigel® (P = 0.0210). Though overall preference was quite polarized, 21 participants preferred H1 intervention formulation and 17 preferred the Hopirub®/Hopigel® formulation that they normally used in their care activities.

Conclusion

We observed a difference in acceptability and strongly polarized preferences among the participants' reactions to the formulations tested. These results indicate that giving healthcare workers a choice between different high-quality products is important to ensure maximum acceptability.

Results of an international pilot survey on health care environmental hygiene at the facility level

BACKGROUND

Health care-associated infections (HAIs) are a major threat to patient safety worldwide. The importance of the health care environment in patient care is not always adequately addressed. Currently, no overview exists of how health care environmental hygiene (HEH) is performed around the world.

METHODS

Our pilot survey tested a preliminary version of a framework for HEH self-assessment. It aimed to gather data to improve the framework as well as evaluate the strengths and challenges in HEH programs around the world, and across resource levels. The survey was developed by a group of experts, and based on the hand hygiene multimodal improvement strategy. The online survey was sent to 743 health care facilities (HCFs) from all of the World Bank income levels, aiming for at least 4 participants from each level. Overall responses were analyzed as a group as well as stratified per income level using OpenEpi.

RESULTS

Overall, 51 HCFs from 35 countries participated. Almost all HCFs surveyed (50/51, 98%) were found lacking in some or all of the 5 components of the WHO multimodal strategy independent of income level. The results demonstrate the widespread challenges in HEH institutions are facing around the world.

CONCLUSION

The feedback from survey participants allowed for the improvement of the self-assessment tool. There is a clear need for more focus on and investment in HEH programs in HCFs worldwide.

First nationwide survey of infection prevention and control among healthcare facilities in Japan: impact of the national regulatory system

BACKGROUND

Infection prevention and control (IPC) measures in Japan are facilitated by a financial incentive process at the national level, where facilities are categorized into three groups (Tier 1, Tier 2, or no financial incentive). However, its impact on IPC at the facility level using a validated tool has not been measured.

METHODS

A nationwide cross-sectional study was conducted from August 2019 to January 2020 to evaluate the situation of IPC programs in Japan, using the global IPC Assessment Framework (IPCAF) developed by the World Health Organization. Combined with the information on the national financial incentive system, the demographics of facilities and each IPCAF item were descriptively analyzed. IPCAF scores were analyzed according to the facility level of care and the national financial incentive system for IPC facility status, using Dunn-Bonferroni and Mann-Whitney U tests.

RESULTS

Fifty-nine facilities in Japan responded to the IPCAF survey: 34 private facilities (57.6%) and 25 public facilities (42.4%). Of these, 11 (18.6%), 29 (49.2%), and 19 (32.3%) were primary, secondary, and tertiary care facilities, respectively. According to the national financial incentive system for IPC, 45 (76.3%), 11 (18.6%), and three (5.1%) facilities were categorized as Tier 1, Tier 2, and no financial incentive system, respectively. Based on the IPCAF total score, more than half of the facilities were categorized as "Advanced" (n = 31, 55.3%), followed by "Intermediate" (n = 21, 37.5%). The IPCAF total score increased as the facility level of care increased, while no statistically significant difference was identified between the secondary and tertiary care facilities (p = 0.79). There was a significant difference between Tier 1 and Tier 2 for all core components and total scores. Core components 5 (multimodal strategies for implementation of IPC interventions) and 6 (monitoring/audit of IPC and feedback) were characteristically low in Japan with a median score of 65.0 (interquartile range 40.0-85.0) and 67.5 (interquartile range 52.5-87.5), respectively.

CONCLUSIONS

The national financial incentive system was associated with IPC programs at facility level in Japan. The current financial incentive system does not emphasize the multimodal strategy or cover monitoring/audit, and an additional systematic approach may be required to further promote IPC for more practical healthcare-associated infection prevention.

Are emojis ready to promote the WHO 5 moments for hand hygiene in healthcare?

Background

Hand hygiene is universally recognized as a cornerstone measure for the prevention of healthcare-associated infections. Although the WHO “My five Moments for hand hygiene” poster has been used for more than a decade to delineate hand hygiene indications and promote action, adherence levels among healthcare workers are still notoriously low and disquieting. To compensate for the lack of effective hand hygiene communication, we aimed to evaluate emojis as possible surrogates for the non-verbal aspects of hand hygiene behaviour.

Methods

Following a thorough review of the Unicode version 12.0, the most applicable emojis to the terms used in the WHO 5 Moments poster were extracted. We developed a self-administered questionnaire to assess the view of infection prevention and control (IPC) practitioners regarding the use of emojis to show the WHO 5 Moments. Completed questionnaires were collected and analysed to determine the suitability of the existing emojis to illustrate a unified emoji poster. Data were analysed using R (version 3.6.3).

Results

A total of 95 IPC practitioners completed the questionnaire from May to October 2019 from different countries. Of these, 69 (74%) were female, and the mean age of the participants was 44.6 ± 10.87 years. We found appropriate emojis for six of the words used in the poster, including for touching (72%), for patient (63%), for clean (53%), for procedure (56%), for body fluid (58%), and for exposure risk (71%). The existing emojis proposed for the words “hygiene”, “aseptic”, and “surrounding” seemed to be less satisfactory.

Conclusions

In summary, the findings of this study indicate that the existing emojis may not be able to substitute the words used in the WHO 5 Moments poster. Emojis might be helpful to address hand hygiene indications in healthcare that may eventually play a role in promoting this measure. However, emojis should be further studied to choose the most appropriate ones and avoid ambiguity and misinterpretation. More emojis to convey health related messages are needed. We recommend further research in this area to evaluate the effect of using emojis in healthcare-related behaviours.

Hand hygiene improvement of individual healthcare workers: results of the multicentre PROHIBIT study

BACKGROUND

Traditionally, hand hygiene (HH) interventions do not identify the observed healthcare workers (HWCs) and therefore, reflect HH compliance only at population level. Intensive care units (ICUs) in seven European hospitals participating in the "Prevention of Hospital Infections by Intervention and Training" (PROHIBIT) study provided individual HH compliance levels. We analysed these to understand the determinants and dynamics of individual change in relation to the overall intervention effect.

METHODS

We included HCWs who contributed at least two observation sessions before and after intervention. Improving, non-changing, and worsening HCWs were defined with a threshold of 20% compliance change. We used multivariable linear regression and spearman's rank correlation to estimate determinants for the individual response to the intervention and correlation to overall change. Swarm graphs visualized ICU-specific patterns.

RESULTS

In total 280 HCWs contributed 17,748 HH opportunities during 2677 observation sessions. Overall, pooled HH compliance increased from 43.1 to 58.7%. The proportion of improving HCWs ranged from 33 to 95% among ICUs. The median HH increase per improving HCW ranged from 16 to 34 percentage points. ICU wide improvement correlated significantly with both the proportion of improving HCWs (ρ = 0.82 [95% CI 0.18-0.97], and their median HH increase (ρ = 0.79 [0.08-0.97]). Multilevel regression demonstrated that individual improvement was significantly associated with nurse profession, lower activity index, higher nurse-to-patient ratio, and lower baseline compliance.

CONCLUSIONS

Both the proportion of improving HCWs and their median individual improvement differed substantially among ICUs but correlated with the ICUs' overall HH improvement. With comparable overall means the range in individual HH varied considerably between some hospitals, implying different transmission risks. Greater insight into improvement dynamics might help to design more effective HH interventions in the future.

Comparing surgeons' skin tolerance and acceptability to alcohol-based surgical hand preparation vs traditional surgical scrub: A matched quasi-experimental study

BACKGROUND

We aimed to compare the tolerance and acceptability of alcohol-based surgical hand preparation versus handscrubbing with antimicrobial soap and water by surgeons.

METHODS

Matched quasi-experimental trial in an academic quaternary care hospital in Ribeirão Preto, Brazil, from April 1 to October, 31, 2017. Participants were cardiac and orthopedics surgeons from the study facility. In the first study phase, they performed handscrubbing with either 2% chlorhexidine (CHG) or 10% iodopovidone (PVP-I) and, in the second phase, they performed handrubbing with alcohol-based handrub (ABHR). Surgeons' skin tolerance and acceptability were evaluated using WHO-validated tools. Data were analyzed using the MacNemar's test within STATA.

RESULTS

A total of 33 surgeons participated to the "per protocol" population; the majority were male (94%); mean age of 35 years (SD, 8.5). On product tolerance, there was a minimal variation in redness, scaliness, fissures, and visual evaluation of the skin when handrubbing with ABHR was compared to handscrubbing with either PVP-I or CHX. Regarding acceptability, participants rated better handrubbing with ABHR than handscrubbing with PVP-I when assessing product smell (66.6% vs 0%, p=0.002), color (73.3% vs 0%, p=0.001), product texture (60% vs 0%, p=0.004), skin dryness (60% vs 0%, p=0.004), ease of application (66.6% vs 0%, p=0.002) and overall satisfaction (66.6% vs 6.7% p=0.011). Participants rated similarly handrubbing with ABHR and handscrubbing with CHX, except for product texture, where handrubbing rated better (71,4% vs. 0%, p=0.002). Handrubbing with ABHR was preferred by 73.3%.

CONCLUSION

Although handrubbing and handscrubbing were equally well tolerated by surgeons, alcohol-based surgical hand preparation fell into the personal preference for most of them.

Comparing the effectiveness of hand hygiene techniques in reducing the microbial load and covering hand surfaces in healthcare workers: Updated systematic review

BACKGROUND

This review, commissioned by the World Health Organization (WHO), examined the effectiveness of the WHO 6-step hand hygiene (HH) technique in reducing microbial load on hands and covering hand surfaces, and compared its effectiveness to other techniques.

METHODS

Medline, CINAHL, ProQuest, Web of Science, Mednar, and Google Scholar were searched for primary studies, published in English (1978-February 2021), evaluating the microbiological effectiveness or hand surface coverage of HH techniques in healthcare workers. Reviewers independently performed quality assessment using Cochrane tools. The protocol for the narrative review was registered (PROSPERO 2021: CRD42021236138).

RESULTS

Nine studies were included. Evidence demonstrated that the WHO technique reduced microbial load on hands. One study found the WHO technique more effective than the 3-step technique (P = .02), while another found no difference between these 2 techniques (P = .08). An adapted 3-step technique was more effective than the WHO technique in laboratory settings (P = .021), but not in clinical practice (P = .629). One study demonstrated that an adapted 6-step technique was more effective than the WHO technique (P = .001). Evidence was heterogeneous in application time, product, and volume. All studies were high risk of bias.

CONCLUSIONS

Eight studies found that the WHO 6-step technique reduced microbial load on healthcare workers' hands; but the studies were heterogeneous and further research is required to identify the most effective, yet feasible technique.

Ethanol is indispensable for virucidal hand antisepsis: memorandum from the alcohol-based hand rub (ABHR) Task Force, WHO Collaborating Centre on Patient Safety, and the Commission for Hospital Hygiene and Infection Prevention (KRINKO), Robert Koch Institute, Berlin, Germany

BACKGROUND

The approval of ethanol by the Biocidal Products Regulation has been under evaluation since 2007. This follows concern over alcohol uptake from ethanol-based hand rubs (EBHR). If ethanol is classified as carcinogenic, mutagenic, or reprotoxic by the European Chemicals Agency (ECHA), then this would affect infection prevention and control practices.

AIM

A review was performed to prove that ethanol is toxicological uncritical and indispensable for hand antisepsis because of its unique activity against non-enveloped viruses and thus the resulting lack of alternatives. Therefore, the following main points are analyzed: The effectiveness of ethanol in hand hygiene, the evidence of ethanol at blood/tissue levels through hand hygiene in healthcare, and the evidence of toxicity of different blood/tissue ethanol levels and the non-comparability with alcoholic consumption and industrial exposure.

RESULTS

EBHR are essential for preventing infections caused by non-enveloped viruses, especially in healthcare, nursing homes, food industry and other areas. Propanols are effective against enveloped viruses as opposed to non-enveloped viruses but there are no other alternatives for virucidal hand antisepsis. Long-term ingestion of ethanol in the form of alcoholic beverages can cause tumours. However, lifetime exposure to ethanol from occupational exposure < 500 ppm does not significantly contribute to the cancer risk. Mutagenic effects were observed only at doses within the toxic range in animal studies. While reprotoxicity is linked with abuse of alcoholic beverages, there is no epidemiological evidence for this from EBHR use in healthcare facilities or from products containing ethanol in non-healthcare settings.

CONCLUSION

The body of evidence shows EBHRs have strong efficacy in killing non-enveloped viruses, whereas 1-propanol and 2-propanol do not kill non-enveloped viruses, that pose significant risk of infection. Ethanol absorbed through the skin during hand hygiene is similar to consumption of beverages with hidden ethanol content (< 0.5% v/v), such as apple juice or kefir. There is no risk of carcinogenicity, mutagenicity or reprotoxicity from repeated use of EBHR. Hence, the WHO Task Force strongly recommend retaining ethanol as an essential constituent in hand rubs for healthcare.

Lower risk of peripheral venous catheter-related bloodstream infection by hand insertion

INTRODUCTION

Little is known about the bloodstream infection (BSI) risk associated with short-term peripheral venous catheters (PVCs) and no large study investigated the insertion site-related risk for PVC-BSI.

METHODS

We performed a cohort study at the University of Geneva Hospitals using the prospective hospital-wide BSI surveillance database. We analyzed the association between insertion site and risk of PVC-BSI on the upper extremity using univariable and multivariable marginal Cox models.

RESULTS

Between 2016 and 2020, utilization of 403'206 peripheral venous catheters were prospectively recorded in a 2000-bed hospital consortium with ten sites. Twenty-seven percent of PVC (n = 109'686) were inserted in the hand. After adjustment for confounding factors, hand insertion was associated with a decreased PVC-BSI risk (adjusted hazard ratio [HR] 0.42, 95% CI 0.18-0.98, p = 0.046) compared to more proximal insertion sites. In a sensitivity analysis for PVCs with ≥ 3 days of dwell time, we confirmed a decreased PVC-BSI risk after hand insertion (HR 0.37, 95% CI 0.15-0.93, p = 0.035).

CONCLUSION

Hand insertion should be considered for reducing PVC infections, especially for catheters with an expected dwell time of more than 2 days.

Implementation of hand hygiene in health-care facilities: results from the WHO Hand Hygiene Self-Assessment Framework global survey 2019

BACKGROUND

Hand hygiene is at the core of effective infection prevention and control (IPC) programmes. 10 years after the development of the WHO Multimodal Hand Hygiene Improvement Strategy, we aimed to ascertain the level of hand hygiene implementation and its drivers in health-care facilities through a global WHO survey.

METHODS

From Jan 16 to Dec 31, 2019, IPC professionals were invited through email and campaigns to complete the online Hand Hygiene Self-Assessment Framework (HHSAF). A geospatial clustering algorithm selected unique health-care facilities responses and post-stratification weighting was applied to improve representativeness. Weighted median HHSAF scores and IQR were reported. Drivers of the HHSAF score were determined through a generalised estimation equation.

FINDINGS

3206 unique responses from 90 countries (46% WHO Member States) were included. The HHSAF score indicated an intermediate hand hygiene implementation level (350 points, IQR 248-430), which was positively associated with country income level and health-care facility funding structure. System Change had the highest score (85 points, IQR 55-100), whereby alcohol-based hand rub at the point of care has become standard practice in many health-care facilities, especially in high-income countries. Institutional Safety Climate had the lowest score (55 points, IQR 35-75). From 2015 to 2019, the median HHSAF score in health-care facilities participating in both HHSAF surveys (n=190) stagnated.

INTERPRETATION

Most health-care facilities had an intermediate level of hand hygiene implementation or higher, for which health-care facility funding and country income level were important drivers. Availability of resources, leadership, and organisational support are key elements to further improve quality of care and provide access to safe care for all.

The first WHO global survey on infection prevention and control in health-care facilities

BACKGROUND

WHO core components for infection prevention and control (IPC) are important building blocks for effective IPC programmes. To our knowledge, we did the first WHO global survey to assess implementation of these programmes in health-care facilities.

METHODS

In this cross-sectional survey, IPC professionals were invited through global outreach and national coordinated efforts to complete the online WHO IPC assessment framework (IPCAF). The survey was created in English and was then translated into ten languages: Arabic, Chinese, English, French, German, Italian, Japanese, Russian, Spanish, and Thai. Post-stratification weighting was applied and countries with low response rates were excluded to improve representativeness. Weighted median scores and IQRs as well as weighted proportions (Nw) meeting defined IPCAF minimum requirements were reported. Indicators associated with the IPCAF score were assessed using a generalised estimating equation.

FINDINGS

From Jan 16 to Dec 31, 2019, 4440 responses were received from 81 countries. The overall weighted IPCAF median score indicated an advanced level of implementation (605, IQR 450·4-705·0), but significantly lower scores were found in low-income (385, 279·7-442·9) and lower-middle-income countries (500·4, 345·0-657·5), and public facilities (515, 385-637·8). Core component 8 (built environment; 90·0, IQR 75·0-100·0) and core component 2 (guidelines; 87·5, 70·0-97·5) scored the highest, and core component 7 (workload, staffing, and bed occupancy; 70·0, 50-90) and core component 3 (education and training; 70 ·0, 50·0-85·0) scored the lowest. Overall, only 15·2% (Nw: 588 of 3873) of facilities met all IPCAF minimum requirements, ranging from 0% (0 of 417) in low-income countries to 25·6% (278 of 1087) in primary facilities, 9% (24 of 268) in secondary facilities, and 19% (18 of 95) in tertiary facilities in high-income countries.

INTERPRETATION

Despite an overall high IPCAF score globally, important gaps in IPC facility implementation and core components across income levels hinder IPC progress. Increased support for more effective and sustainable IPC programmes is crucial to reduce risks posed by outbreaks to global health security and to ensure patient and health worker safety.

A 'whole of United Nations approach' to tackle antimicrobial resistance? A mapping of the mandate and activities of international organisations

The 2015 World Health Organization Global Action Plan and other international policy documents have stressed the need for a 'whole of United Nations approach' in addressing antimicrobial resistance (AMR). As several years have passed, the goal of this paper is to take stock of the current role, mandate, and activities of international organisations and other global stakeholders on AMR. Relevant information is identified through a web-based search and a review of policy documents from international organisations. Based on the assessment of 78 organisations, 21 have AMR-specific activities in the broader sense, although for many of these organisations, their involvement is limited in scope, and 36 have AMR-sensitive activities reflecting the wide scope of AMR. An interdisciplinary framework based on six relevant challenges of global collective actions regarding AMR as well as the main functions of international organisations in global governance is used to organise the findings into several 'clusters'. AMR is not a priority for many international organisations, but some of them can leverage current efforts to tackle AMR while contributing to their core agenda. Overall, a 'whole of UN approach' to AMR within the framework of Sustainable Development Goals is critical to move the global governance of AMR forward.
