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

WHO global research agenda for hand hygiene improvement in health care: a Delphi consensus study

OBJECTIVE

To identify global research priorities for improving hand hygiene in healthcare settings and develop a 2023-2030 research agenda to guide funding, coordinate research, promote investment, and inform policy for enhanced healthcare quality and safety.

DESIGN

Expert consensus study using a modified Delphi process.

PARTICIPANTS

A 105-member panel of international hand hygiene experts including the World Health Organization (WHO) Technical Advisory Group of Experts on Hand Hygiene in Healthcare representing all WHO regions and World Bank income levels.

METHODS

The research priorities were identified through a multiphase approach including a meta-review to establish knowledge gaps and inform initial priorities, followed by expert consultations using a modified Delphi process. 192 preliminary priorities were included in a two-round Delphi survey. Experts rated each priority in the first round, and then reviewed and adjusted responses based on the panel's aggregated, anonymous responses in the second round. Ratings were collected on a five-point Likert scale. Consensus was defined as a combined "strongly agree" and "agree" frequency of at least 70%.

RESULTS

Consensus was achieved for 178 of 192 priorities (92.7%), categorized into six domains: system change; training and education; evaluation and feedback; reminders and communications; institutional safety climate; and hand hygiene improvement impact on healthcare-associated infections and antimicrobial resistance. Of these, 121 priorities reached >80% consensus. The Delphi process, maintained a 92% response rate over two rounds.

CONCLUSIONS

A structured consensus process yielded a research agenda to address gaps in hand hygiene improvement, supporting enhanced healthcare quality and safety globally.

Immersive technology and hand hygiene: scoping review

BACKGROUND

The use of immersive technology in healthcare education is on the rise, yet its impact on learner engagement, knowledge retention, and specifically in areas like hand hygiene training, remains underexplored. The aim of this scoping review was to summarize the existing studies of immersive technology in hand hygiene training of healthcare providers and health professions students.

METHODS

A scoping review following the Levac et al. framework was conducted. The literature search was performed in databases PubMed, CINAHL Ultimate, ScienceDirect (Elsevier), Web of Science in addition to Google Scholar and ProQuest Dissertation & Theses. The Preferred Reporting Items for Systematic Reviews and Meta-Analysis: Extension for Scoping Reviews (PRIMSA-ScR) guideline was used to report the results. We analysed data using tabular and descriptive summary.

RESULTS

In the final analysis 11 studies from seven countries were included. Most of the studies (n = 10, 90,91%) used virtual reality in hand hygiene training of healthcare providers and health professions students. Most studies have found that immersive technology is useful in teaching hand hygiene (n = 6, 54,55%). There are some theories and concepts that support the teaching of hand hygiene with immersive technology, but most of the research is not supported by them. Theories or concepts were included in two studies (18,18%).

CONCLUSION

Immersive technology, especially virtual reality, enhances hand hygiene learning and engagement compared to traditional methods. However, most studies lack theoretical support. To advance this field, exploring immersive technology for further research and incorporating relevant theories is encouraged. Additionally, conducting a thorough cost-effectiveness analysis and establishing a robust evaluation framework, encompassing both short-term and long-term outcomes, will be beneficial for a comprehensive understanding of the impact of immersive technology in hand hygiene education.

WHO research agenda on the role of the institutional safety climate for hand hygiene improvement: a Delphi consensus-building study

BACKGROUND

Creating and sustaining an institutional climate conducive to patient and health worker safety is a critical element of successful multimodal hand hygiene improvement strategies aimed at achieving best practices. Repeated WHO global surveys indicate that the institutional safety climate consistently ranks the lowest among various interventions.

METHODS

To develop an international expert consensus on research agenda priorities related to the role of institutional safety climate within the context of a multimodal hand hygiene improvement strategy, we conducted a structured consensus process involving a purposive sample of international experts. A preliminary list of research priorities was formulated following evidence mapping, and subsequently refined through a modified Delphi consensus process involving two rounds. In round 1, survey respondents were asked to rate the importance of each research priority. In round 2, experts reviewed round 1 ratings to reach a consensus (defined as ≥70% agreement) on the final prioritised items to be included in the research agenda. The research priorities were then reviewed and finalised by members of the WHO Technical Advisory Group on Hand Hygiene Research in Healthcare.

RESULTS

Of the 57 invited participants, 50 completed Delphi round 1 (88%), and 48 completed round 2 (96%). Thirty-six research priority statements were included in round 1 across five thematic categories: (1) safety climate; (2) personal accountability for hand hygiene; (3) leadership; (4) patient participation and empowerment and (5) religion and traditions. In round 1, 75% of the items achieved consensus, with 9 statements carried forward to round 2, leading to a final set of 31 prioritised research statements.

CONCLUSION

This research agenda can be used by researchers, clinicians, policy-makers and funding bodies to address gaps in hand hygiene improvement within the context of an institutional safety climate, thereby enhancing patient and health worker safety globally.

Infection prevention and control in conflict-affected areas in northeast Syria: A cross-sectional study

Objectives

In northeastern Syria (NES), the adherence of health care facilities to infection prevention and control (IPC) standards remains underexplored. This study evaluates the IPC performance of various health facilities against World Health Organization (WHO) benchmarks using the IPC Assessment Framework (IPCAF) and the Hand Hygiene Self-Assessment Framework (HHSAF).

Methods

We conducted a cross-sectional survey of 33 health care facilities, including primary (PHC), secondary (SHC), and tertiary health care centres (THC). Data were collected via on-site evaluations using the IPCAF and HHSAF tools.

Results

A significant 91% of facilities did not meet half of the WHO IPC minimum requirements. Specifically, 57% of PHCs met 26-50% of the standards, while none exceeded 75%. Among SHCs, 71% met 26-50% of the standards, while 44% of THCs fell within this range. Notably, 81.8% of facilities were classified as 'inadequate' per the IPCAF, with none achieving 'intermediate' or 'advanced' levels. The HHSAF results were similarly concerning, with 34.4% deemed 'inadequate' and 65.6% at the 'basic' level. A weak positive correlation (0.137) was found between IPCAF and HHSAF scores.

Conclusions

NES health care facilities demonstrate substantial deficiencies in IPC compliance, with critical gaps in IPC programmes, health care-associated infection surveillance, and training. Urgent interventions are required to enhance IPC practices, leveraging local strengths and fostering international collaborations to improve patient safety and health care quality in the region.

Ten years of hand hygiene excellence: a summary of outcomes, and a comparison of indicators, from award-winning hospitals worldwide

BACKGROUND

Hand hygiene is a crucial measure for the prevention of healthcare-associated infections (HAIs). The Hand Hygiene Excellence Award (HHEA) is an international programme acknowledging healthcare facilities for their leadership in implementing hand hygiene improvement programmes, including the World Health Organisation's Multimodal Improvement Strategy. This study aimed at summarising the results of the HHEA campaign between 2010 and 2021 and investigating the relationship between different hand hygiene parameters based on data from participating healthcare facilities.

METHODS

A retrospective analysis was performed on datasets from HHEA forms, including data on hand hygiene compliance, alcohol-based handrub (ABHR) consumption, and Hand Hygiene Self-Assessment Framework (HHSAF) scores. Descriptive statistics were reported for each variable. The correlation between variables was inspected through Kendall's test, while possible non-linear relationships between hand hygiene compliance, ABHR consumption and HHSAF scores were sought through the Locally Estimated Scatterplot Smoothing or logistic regression models. A tree-structured partitioning model was developed to further confirm the obtained findings.

RESULTS

Ninety-seven healthcare facilities from 28 countries in three world regions (Asia-Pacific, Europe, Latin America) were awarded the HHEA and thus included in the analysis. HHSAF scores indicated an advanced hand hygiene promotion level (median 445 points, IQR 395-480). System change (100 [95-100] points) and institutional safety climate (85 [70-95] points) showed the highest and lowest score, respectively. In most cases, hand hygiene compliance was above 70%, with heterogeneity between countries. ABHR consumption above 20 millilitres per patient-day (ml/PD) was widely reported, with overall increasing trends. HHSAF scores were positively correlated with hand hygiene compliance (τ = 0.211, p = 0.007). We observed a positive correlation between compliance rates and ABHR consumption (τ = 0.193, p < 0.001), although the average predicted consumption was stable around 55-60 ml/PD for compliance rates above 80-85%. Logistic regression and partitioning tree analyses revealed that higher HHSAF scores were more likely in the high-ABHR consumption group at cut-offs around 57-59 ml/PD.

CONCLUSION

Ten years after its inception, the HHEA proves to be a valuable hand hygiene improvement programme in healthcare facilities worldwide. Consistent results were provided by the different hand hygiene indicators and the HHSAF score represents a valuable proxy measure of hand hygiene compliance.

Nursing students led simulations to improve healthcare workers' hand hygiene compliance

BACKGROUND

Hand hygiene compliance (HHC) is recognised as a major factor in the prevention of healthcare-associated infections. Healthcare workers (HCWs) compliance is still suboptimal. Simulation as an educational strategy may contribute to improved performance.

OBJECTIVE

This study aimed to assess the effect of simulation interventions led by nursing students on HCWs' HHC.

METHOD

A prospective quasi-experimental design with before and after intervention measurements was implemented in an 1150-bed tertiary hospital. Four consecutive periods, measuring before and after HHC, were examined in four hospital divisions. For each division, unique simulation activities were developed and led by nursing students, educators, and hospital leaders. Sixty seven students and 286 healthcare workers, along with two nurse educators, participated in the simulation sessions. HHC of all HCWs in the divisions was assessed by hospital infection control personnel.

RESULTS

Hospital HHC rose across the four periods in all four divisions during this study. In three out of four periods and divisions, HHC increased significantly more in the simulation intervention groups compared to the overall hospital improvement.

CONCLUSION

Student-led simulation for HCWs is an additional effective method to improve HHC. Nursing managers should consider joining forces with nursing educators to enable students to become agents of change in healthcare settings and encourage further collaboration.

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.

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.

Water, Sanitation, and Hygiene and Infection Prevention and Control in Jordanian Hospitals in the Context of COVID-19: A National Assessment

Purpose

To identify areas that need improvement in Jordanian health centers regarding infection prevention and control (IPC) programs; water, sanitation, and hygiene (WASH) services; and other protective measures, especially in the context of coronavirus disease (COVID-19).

Methods

This is a national assessment study that comprised hospitals of different sectors in Jordan, including, Ministry of Health (MoH), private, and military hospitals. The study included 23 Jordanian hospitals. Assessment tools were developed and adapted mainly from the WASH Facility Improvement Tool (WASH FIT) and other tools. Hospitals were assessed to meet targets based on whether indicators were fully met, partially met, or not met.

Results

The mean percentage of the 150 indicators that met the standards was 83.2% (72.6% for MoH, 84.5% for private, and 90.4% for military hospitals). The percentage of indicators, both WASH/IPC and training and education indicators, that met the targets were higher in military hospitals than in MoH and private hospitals. However, in context of COVID-19, only 64.7% of indicators related to precautionary measures were met by all hospitals.

Conclusion

The data available on WASH/IPC in Jordan are scarce, and the study findings will help in preventing severe consequences of the COVID-19 pandemic. There is scope for improvement in many WASH/IPC aspects, and urgent actions should be taken, especially to fill the gaps in COVID-19 precautionary measures.

How Well Are Hand Hygiene Practices and Promotion Implemented in Sierra Leone? A Cross-Sectional Study in 13 Public Hospitals

Healthcare-associated infections (HAIs) result in millions of avoidable deaths or prolonged lengths of stay in hospitals and cause huge economic loss to health systems and communities. Primarily, HAIs spread through the hands of healthcare workers, so improving hand hygiene can reduce their spread. We evaluated hand hygiene practices and promotion across 13 public health hospitals (six secondary and seven tertiary hospitals) in the Western Area of Sierra Leone in a cross-sectional study using the WHO hand hygiene self-Assessment framework in May 2021. The mean score for all hospitals was 273 ± 46, indicating an intermediate level of hand hygiene. Nine hospitals achieved an intermediate level and four a basic level. More secondary hospitals 5 (83%) were at the intermediate level, compared to tertiary hospitals 4 (57%). Tertiary hospitals were poorly rated in the reminders in workplace and institutional safety climate domains but excelled in training and education. Lack of budgets to support hand hygiene implementation is a priority gap underlying this poor performance. These gaps hinder hand hygiene practice and promotion, contributing to the continued spread of HAIs. Enhancing the distribution of hand hygiene resources and encouraging an embedded culture of hand hygiene practice in hospitals will reduce HAIs.

Safety in fragile, conflict-affected, and vulnerable settings: An evidence scanning approach for identifying patient safety interventions

Background

The number of people living in fragile, conflict-affected, and vulnerable (FCV) settings is growing rapidly and attention to achieving universal health coverage must be accompanied by sufficient focus on the safety of care for universal access to be meaningful. Healthcare workers in these settings are working under extreme conditions, often with insufficient contextualized evidence to support decision-making. Recognising the relative paucity of, and methodological issues in gathering evidence from these settings, the evidence scanning described in this paper considered which patient safety interventions might offer the 'better bet', eg, the most effective and appropriate intervention in FCV settings.

Methods

An evidence scanning approach was used to examine the literature. The search was limited to FCV settings and low-income settings as defined by the World Bank, but if a systematic review included a mix of evidence from FCV/low income settings, as well as low-middle income settings, it was included. The search was conducted in English and limited to studies published from 2003 onwards, utilising Google Scholar as a publicly accessible database and further review of the grey literature, with specific attention to the outputs of non-governmental organisations. The search and subsequent analysis were completed between April and June 2020.

Results

The majority of studies identified related to strengthening infection prevention and control which was also found to be the 'better bet' intervention that could generalise to other settings, be most feasible to implement, and most effective for improving patient care and associated outcomes. Other prioritized interventions include risk management, with contributing elements such as reporting, audits, and death review processes.

Conclusions

Infection prevention and control interventions dominate in the literature for multiple reasons including strength of evidence, acceptability, feasibility, and impact on patient and health worker well-being. However, there is an urgent need to further develop the evidence base, specialist knowledge, and field guidance on a range of other patient safety interventions such as education and training, patient identification, subject specific safety actions, and risk management.

Impact of Infection Control Education on Gastrointestinal Endoscopy Procedural Staff

To date, minimal research has been conducted on proper use of personal protective equipment and hand hygiene within endoscopy. The American Society for Gastrointestinal Endoscopy has developed guidelines for infection control within the endoscopy suite. A practice change based upon these guidelines was implemented. Education was provided to endoscopy procedural staff within a Midwestern hospital based upon the World Health Organization 5 Moments for Hand Hygiene initiative and included personal protective equipment. Knowledge, skills, and attitudes of the participant group were compared from paired pre- to posteducation surveys pertaining to hand hygiene and personal protective equipment. Observation of personal protective equipment use and hand hygiene implementation during procedures was also documented pre- to posteducation. The project results revealed both willingness to implement proper donning and doffing of personal protective equipment and improved technique as evidenced by improved observed technique with the endoscopy suite and moderately improved hand hygiene questionnaire results. Although conducted as a quality improvement project, clinical significance was found via observation following education. These practices can aid in reduction of organism transmission from patients to staff.

An Intra-COVID-19 Assessment of Hand Hygiene Facility, Policy and Staff Compliance in Two Hospitals in Sierra Leone: Is There a Difference between Regional and Capital City Hospitals?

Although hand hygiene (HH) is the most effective intervention to reduce the spread of infections, there are limited data on HH facilities, policy, and compliance in sub-Saharan Africa. This cross-sectional study is aimed at assessing HH using the WHO HH self-assessment framework, HH technical reference manual, and a modified infection control self-assessment tool in two hospitals in Sierra Leone. Only 10% and 9% of regional and capital city hospitals had running tap water, respectively. Veronica buckets were the resources for HH in 89% of units in the regional hospital and 92% of units in capital city hospital. Constant supply of soap and alcohol-based hand rub was available in 82% and 68%; and 74% and 79% of units in the capital city and regional hospitals, respectively. Only 10% of the units in both hospitals had hand-drying facilities and functional sinks. Overall HH compliance for the two hospitals was 18.6% and was higher in the regional (20.8%) than the capital city (17.0%) hospitals. The HH levels for the capital city and regional hospitals were 277.5 and 262.5 respectively. Despite the COVID-19 pandemic, there are still challenges with HH compliance in Sierra Leone. It is, therefore, necessary to strengthen the HH multi-modal strategy.

Infection Prevention and Control Measures at the Children Hospital Lahore: A My Child Matters Collaborative Project

PURPOSE

Infection prevention among children with cancer is a major challenge at Children Hospital Lahore (CHL), a public health care facility in Pakistan with 1,000 new pediatric cancer admissions annually. The objective has been to reduce infections through collaboration between CHL and the St Jude Children's Hospital Global Infectious Disease program via a grant by the Sanofi Espoir foundation through the My Child Matters program. The aim of the current study was to describe the effect of the collaborative improvement strategy on existing infection prevention and control (IPC) standards at CHL.

MATERIALS AND METHODS

Our work was a prospective before-and-after study to improve IPC standards. We compared the WHO Hand Hygiene Self-Assessment Framework and four modules of the St Jude modified Infection Control Assessment Tool (ICAT) scores over a 3-year period. Our strategy included creating a multidisciplinary team of pediatric oncologists, infectious disease physicians, nurses, a microbiologist, and a data manager; engaging in monthly online IPC mentoring sessions with St Jude Children's Hospital Global Infectious Disease program and My Child Matters mentors; performing daily inpatient health care-associated infection surveillance rounds; and performing regular hand hygiene training and compliance audits.

RESULTS

Baseline needs assessment showed health care-associated infections identified by positive blood cultures as 8.7 infections per 1,000 patient-days. Deficient hand hygiene supplies, health education measures, and bed sharing of neutropenic patients were identified as major challenges. Our hand hygiene facility level, per WHO scores, increased from Inadequate to Intermediate/Consolidation by the end of the 3-year implementation (122 v 352 WHO Hand Hygiene Self-Assessment Framework scores). The sink:bed and hand sanitizer:bed ratios improved to 1:6 and 1:1, respectively. The ICAT general infection control module increased by 40% (45 v 78 ICAT scores) and hygiene compliance improved by 20%.

CONCLUSION

Implementing a collaborative improvement strategy improved IPC standards in our center, which can be easily replicated in other pediatric oncology centers in lower- and middle-income countries.

Impact of national policy on hand hygiene promotion activities in hospitals in Korea

BACKGROUND

After the Middle East respiratory syndrome coronavirus outbreak in Korea in 2015, the Government established a strategy for infection prevention to encourage infection control activities in hospitals. The new policy was announced in December 2015 and implemented in September 2016. The aim of this study is to evaluate how infection control activities improved within Korean hospitals after the change in government policy.

METHODS

Three cross-sectional surveys using the WHO Hand Hygiene Self-Assessment Framework (HHSAF) were conducted in 2013, 2015, and 2017. Using a multivariable linear regression model, we analyzed the change in total HHSAF score according to survey year.

RESULTS

A total of 32 hospitals participated in the survey in 2013, 52 in 2015, and 101 in 2017. The number of inpatient beds per infection control professionals decreased from 324 in 2013 to 303 in 2015 and 179 in 2017. Most hospitals were at intermediate or advanced levels of progress (90.6% in 2013, 86.6% in 2015, and 94.1% in 2017). In the multivariable linear regression model, total HHSAF score was significantly associated with hospital teaching status (β coefficient of major teaching hospital, 52.6; 95% confidence interval [CI], 8.9 to 96.4; P = 0.018), beds size (β coefficient of 100 beds increase, 5.1; 95% CI, 0.3 to 9.8; P = 0.038), and survey time (β coefficient of 2017 survey, 45.1; 95% CI, 19.3 to 70.9; P = 0.001).

CONCLUSIONS

After the new national policy was implemented, the number of infection control professionals increased, and hand hygiene promotion activities were strengthened across Korean hospitals.

Evaluating infection prevention and control programs in Austrian acute care hospitals using the WHO Infection Prevention and Control Assessment Framework

Background

Infection prevention and control (IPC) is crucial for patient safety. The World Health Organization (WHO) has released various tools to promote IPC. In 2018, the WHO released the Infection Prevention and Control Assessment Framework (IPCAF) that enables acute care healthcare facilities to evaluate IPC structures and practices. Data regarding IPC implementation in Austria are scarce. To deliver insights into this topic and promote the IPCAF within the Austrian IPC community, we decided to invite all Austrian hospitals participating in the German nosocomial infection surveillance system to conduct a self-assessment using the WHO IPCAF.

Methods

The IPCAF follows the eight WHO core components of IPC. A German translation of the IPCAF was sent to 127 Austrian acute care hospitals. The survey period was from October to December 2018. Participation in the survey, data entry and transfer to the German national reference center for surveillance of healthcare-associated infections was on a voluntary basis.

Results

Altogether, 65 Austrian hospitals provided a complete dataset. The overall median IPCAF score of all hospitals was 620 (of a possible maximum score of 800), which corresponded to an advanced level of IPC. Of the 65 hospitals, 38 achieved an advanced IPC level. Deeper analysis of the different core components yielded diverse results. Scores were lowest for core components on multimodal strategies for implementation of IPC interventions, and IPC education and training. Around 26% (n = 17) of hospitals reported that the local IPC team was not steadily supported by an IPC committee. Senior clinical staff was not present in the IPC committee in 23% (n = 15) of hospitals. Only 26% (n = 17) of hospitals reported employing at least one IPC professional per ≤250 beds. Surveillance for multidrug-resistant pathogens was not conducted in 26% (n = 17) of hospitals.

Conclusions

Implementation of IPC key aspects is generally at a high level in Austria. However, potentials for improvement were demonstrated, most prominently with regard to staffing, IPC education and training, effective implementation of multimodal strategies, and involvement of professional groups. Our survey demonstrated that the IPCAF is a useful tool for IPC self-assessment and can uncover deficits even in a high-income setting like Austria.

The effect of a 5-year hand hygiene initiative based on the WHO multimodal hand hygiene improvement strategy: an interrupted time-series study

Background

A World Health Organization (WHO) guideline-based multimodal hand hygiene (HH) initiative was introduced hospital-wide to a nonteaching Japanese hospital for 5 years. The objective of this study was to assess the effect of this initiative in terms of changes in alcohol-based hand rub (ABHR) consumption and the Hand Hygiene Self-Assessment Framework (HHSAF) score.

Methods

The consumption of monthly hospital-wide ABHR was calculated in L per 1000 patient days (PDs). The change in ABHR consumption was analysed by an interrupted time series analysis with a pre-implementation period of 36 months and an implementation period of 60 months. The correlation between annual ABHR consumption and the HHSAF score was estimated using Pearson’s correlation coefficients.

Results

The annual ABHR consumption was 4.0 (L/1000 PDs) to 4.4 in the pre-implementation period and 10.4 to 34.4 in the implementation period. The HHSAF score was 117.5 (out of 500) in the pre-implementation period and 267.5 to 445 in the implementation period. A statistically significant increase in the monthly ABHR consumption (change in slope: + 0.479 L/1000 PDs, p <  0.01) was observed with the implementation of the initiative. Annual ABHR consumption was strongly correlated with the annual HHSAF score (r = 0.971, p <  0.01).

Conclusions

A 5-year WHO-based HH initiative significantly increased ABHR consumption. Our study suggested that the HHSAF assessment can be a good process measure to improve HH in a single facility, as ABHR consumption increased with the HHSAF score.

Assessing the Hawthorne effect on hand hygiene compliance in an intensive care unit

Background

The influence of the Hawthorne effect on hand hygiene compliance in an intensive care unit was assessed using covert and overt direct observation.

Methods

The observational study was conducted from February to November 2018 in a 24-bed adult intensive care unit in a 243-bed tertiary care hospital, in four periods (P): P-1, February 5-March 3, 29 h (covert) and P-2, March 15-April 16, 33 h (overt), prior to an educational campaign on hand hygiene; and P-3, August 27-September 28, 33 h (covert) and P-4, October 3-November 6, 35 h (overt), after the campaign. Three 20-min observation sessions were performed daily, randomly distributed in the morning, afternoon and evening shifts, including holidays and weekends. Hand hygiene compliance rates observed in Periods 2 and 4 were displayed on an electronic panel installed in the unit. Hand hygiene compliance was assessed according to the World Health Organization “My Five Moments for Hand Hygiene” guidelines.

Results

Before the campaign, the overall hand hygiene compliance rate was 31.95% (340/1064, covert) versus 68.10% (790/1160, overt), and afterwards was 56.11% (615/1096, covert) versus 80.98% (1086/1341, overt). The infection rate was reduced by 22.62% (18.87% versus 14.60%).

Conclusions

The Hawthorne effect and educational campaign markedly influenced compliance with hand hygiene recommendations. The results suggest that combining overt and covert observation methods, including regular feedback on hand hygiene compliance displayed on an electronic panel, may be a valid alternative to increase real hand hygiene compliance rates in hospital practice.

Hand hygiene promotion delivered by change agents-Two attitudes, similar outcome

OBJECTIVE

To assess the effect of peer-identified change agents (PICAs) compared to management-selected change agents (MSCAs) on hand hygiene behavior in acute care.

DESIGN

Randomized-controlled study.

SETTING

Two internal medicine wards of a public, university-affiliated, tertiary-care hospital in Malaysia.

METHODS

We randomly allocated 2 wards to hand hygiene promotion delivered either by PICAs (study arm 1) or by MSCAs (study arm 2). The primary outcome was hand hygiene compliance using direct observation by validated auditors. Secondary outcomes were hand hygiene knowledge and observations from ward tours.

RESULTS

Mean hand hygiene compliance in study arm 1 and study arm 2 improved from 48% (95% confidence interval [CI], 44%-53%) and 50% (95% CI, 44%-55%) in the preintervention period to 66% (63%-69%) and 65% (60%-69%) in the intervention period, respectively. We detected no statistically significant difference in hand hygiene improvement between the 2 study arms. Knowledge scores on hand hygiene in study arm 1 and study arm 2 improved from 60% and 63% to 98% and 93%, respectively. Staff in study arm 1 improved hand hygiene because they did not want to disappoint the efforts taken by the PICAs. Staff in study arm 2 felt pressured by the MSCAs to comply with hand hygiene to obtain good overall performance appraisals.

CONCLUSION

Although the attitude of PICAs and MSCAs in terms of leadership, mode of action and perception of their task by staff were very different, or even opposed, both PICAs and MSCAs effectively changed behavior of staff toward improved hand hygiene to comparable levels.

Train-the-Trainers in hand hygiene: a standardized approach to guide education in infection prevention and control

Background

Harmonization in hand hygiene training for infection prevention and control (IPC) professionals is lacking. We describe a standardized approach to training, using a “Train-the-Trainers” (TTT) concept for IPC professionals and assess its impact on hand hygiene knowledge in six countries.

Methods

We developed a three-day simulation-based TTT course based on the World Health Organization (WHO) Multimodal Hand Hygiene Improvement Strategy. To evaluate its impact, we have performed a pre-and post-course knowledge questionnaire. The Wilcoxon signed-rank test was used to compare the results before and after training.

Results

Between June 2016 and January 2018 we conducted seven TTT courses in six countries: Iran, Malaysia, Mexico, South Africa, Spain and Thailand. A total of 305 IPC professionals completed the programme. Participants included nurses (n = 196; 64.2%), physicians (n = 53; 17.3%) and other health professionals (n = 56; 18.3%). In total, participants from more than 20 countries were trained. A significant (p < 0.05) improvement in knowledge between the pre- and post-TTT training phases was observed in all countries. Puebla (Mexico) had the highest improvement (22.3%; p < 0.001), followed by Malaysia (21.2%; p < 0.001), Jalisco (Mexico; 20.2%; p < 0.001), Thailand (18.8%; p < 0.001), South Africa (18.3%; p < 0.001), Iran (17.5%; p < 0.001) and Spain (9.7%; p = 0.047). Spain had the highest overall test scores, while Thailand had the lowest pre- and post-scores. Positive aspects reported included: unique learning environment, sharing experiences, hands-on practices on a secure environment and networking among IPC professionals. Sustainability was assessed through follow-up evaluations conducted in three original TTT course sites in Mexico (Jalisco and Puebla) and in Spain: improvement was sustained in the last follow-up phase when assessed 5 months, 1 year and 2 years after the first TTT course, respectively.

Conclusions

The TTT in hand hygiene model proved to be effective in enhancing participant’s knowledge, sharing experiences and networking. IPC professionals can use this reference training method worldwide to further disseminate knowledge to other health care workers.

Testing of the WHO Infection Prevention and Control Assessment Framework at acute healthcare facility level

BACKGROUND

Monitoring and evaluation are an essential part of infection prevention and control (IPC) implementation. The authors developed an IPC assessment framework (IPCAF) to support implementation of the World Health Organization (WHO) guidelines on core components of IPC programmes in acute healthcare facilities.

AIM

To evaluate the usability and reliability of the IPCAF tool for global use.

METHODS

The IPCAF is a questionnaire with a scoring system to measure the level of IPC implementation according to the eight WHO core components. The tool was pre-tested qualitatively, revised and translated selectively. A convenience sample of hospitals was invited to participate in the final testing. At least two IPC professionals from each hospital independently completed the IPCAF and a usability questionnaire online. The tool's internal consistency and interobserver reliability or intraclass correlation coefficient (ICC) were assessed, and usability questions were summarized descriptively.

FINDINGS

In total, 46 countries, 181 hospitals and 324 individuals participated; 52 (16%) and 55 (17%) individual respondents came from low- and lower-middle income countries, respectively. Fifty-two percent of respondents took less than 1 h to complete the IPCAF. Overall, there was adequate internal consistency and a high ICC (0.92, 95% confidence interval 0.89-0.94). Ten individual questions had poor reliability (ICC <0.4); these were considered for revision according to usability feedback and expert opinion.

CONCLUSIONS

The WHO IPCAF was tested using a robust global study and revised as necessary. It is now an effective tool for IPC improvement in healthcare facilities.

Implementing a multi-faceted framework for proprietorship of hand hygiene compliance in a network of South African hospitals: leveraging the Ubuntu philosophy

BACKGROUND

Given the lack of hospital-wide ownership and shortage of nurses, the ideal model for large-scale implementation of hand hygiene (HH) behaviour change in low- and middle-income countries is unknown.

AIM

The aim of the multi-modal strategy was to engender hospital accountability for HH compliance.

METHODS

The quasi-experimental study was conducted in 50 South African hospitals (November 2015 to July 2017) and involved five overlapping phases: executive governance and corporate behaviour change; group-wide systematic situational analysis; development of an electronic-assisted direct-observed data collection and analysis application; launch and implementation; and accountable governance. Measurement of intra- and inter-hospital variance to six HH opportunities was calculated and data compliance dashboards were e-mailed weekly to hospital leadership teams to provide feedback of recorded HH compliance and behaviour to frontline teams. Baseline comparison (July 2016) of compliance was compared versus post-implementation (July 2017).

FINDINGS

Baseline HH compliance of ≤60% was documented for 16% (8/50) of hospitals, whereas overall, 48% (24/50) of hospitals demonstrated a significant improvement (P < 0.01). Over the 13-month observation period, 523,422 observations were recorded with a mean rate of 277 ± 223 observations per 1000 patient-days. The group mean composite compliance improved by 7.8% (P < 0.01) from 77.4% ± 12.8 to 85.2% ± 8.8 between July 2016 and July 2017, respectively.

CONCLUSION

Implementation of a multi-faceted HH model in a large, diverse group of South African hospitals translated into changes in the organizational systems and accountability, standardized HH compliance management and feedback that led to HH proprietorship.

"Clean Care for All-It's in Your Hands": The 5 May 2019 World Health Organization SAVE LIVES: Clean Your Hands Campaign

Each improvement in infection prevention control contributes toward quality universal health coverage.

Hand hygiene in low- and middle-income countries

A panel of experts was convened by the International Society for Infectious Diseases (ISID) to overview evidence based strategies to reduce the transmission of pathogens via the hands of healthcare workers and the subsequent incidence of hospital acquired infections with a focus on implementing these strategies in low- and middle-income countries. Existing data suggests that hospital patients in low- and middle-income countries are exposed to rates of healthcare associated infections at least 2-fold higher than in high income countries. In addition to the universal challenges to the implementation of effective hand hygiene strategies, hospitals in low- and middle-income countries face a range of unique barriers, including overcrowding and securing a reliable and sustainable supply of alcohol-based handrub. The WHO Multimodal Hand Hygiene Improvement Strategy and its associated resources represent an evidence-based framework for developing a locally-adapted implementation plan for hand hygiene promotion.

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.

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.
