Hand hygiene in intensive care units: a matter of time?

S2k-Guideline hand antisepsis and hand hygiene

The consensus-based guideline "hand antisepsis and hand hygiene" for Germany has the following sections: Prevention of nosocomial infections by hygienic hand antisepsis, prevention of surgical site infections by surgical hand antisepsis, infection prevention in the community by hand antisepsis in epidemic or pandemic situations, hand washing, selection of alcohol-based hand rubs and wash lotions, medical gloves and protective gloves, preconditions for hand hygiene, skin protection and skin care, quality assurance of the implementation of hand hygiene measures and legal aspects. The guideline was developed by the German Society for Hospital Hygiene in cooperation with 22 professional societies, 2 professional organizations, the German Care Council, the Federal Working Group for Self-Help of People with Disabilities and Chronic Illness and their Family Members, the General Accident Insurance Institution Austria and the German-speaking Interest Group of Infection Prevention Experts and Hospital Hygiene Consultants.

Drastic hourly changes in hand hygiene workload and performance rates: A multicenter time series analysis

BACKGROUND

High hand hygiene (HH) workload is a commonly cited barrier to optimal HH performance. The objective of this study was to assess trends of HH workload as defined by HH opportunities (HHO) and performance rates over different timescales using automated HH monitoring system data.

METHODS

This multiyear retrospective observational study was conducted in 58 inpatient units located in 10 North American hospitals. HHO and HH rates were analyzed by time series mixed effects general additive model.

RESULTS

Median HH rates peaked at 50.0 between 6 and 7 AM with a trough of 38.2 at 5 PM. HHO over hours in a day were the highest at 184 per hospital unit per hour at 10 AM with a trough of 49.0 between 2 and 3 AM. Median rates for day and night shifts were 40.8 and 45.5, respectively (P = .078). Weekend day shift had the lowest median rate (39.4) compared with any other 12-hour shift (P < .1018). The median rates and HHO varied little across days in a week and months.

CONCLUSIONS

HH workload and performance rates were negatively correlated and changed drastically over hours in a day. Hospitals should consider HH workload in the development and timely delivery of improvement interventions.

Indication-based and patient-based hand hygiene performance among nurses working at a university hospital

The traditional method of monitoring hand hygiene (HH) based on specific indications does not ensure that HH is performed for all required indications during patient care. This study aimed to compare HH performance rates (HHPRs) based on specific indications versus overall patient care among nurses at a university hospital. The study retrospectively analyzed HH monitoring data for 1398 indications from 543 patients and 190 nurses. Observations were conducted continuously, tracking a single healthcare worker from before patient contact until the end of the contact within a 30-min period. The indication-based HHPR was found to be 89.1%, while the patient-based HHPR was 78.1%. In the context of patient-based HHPR, the lowest rates were observed among nurses in the emergency room (48.3%) and those with less than 1 year of work experience (66.7%). Moreover, the largest discrepancy between indication-based and patient-based HHPR was noted among emergency room nurses with less than 1 year of experience. This significant difference underscores the need for patient-based HH monitoring, particularly for nurses in emergency settings and those with limited experience.

Alcohol-based hand rubs can fulfil efficacy requirements of EN 1500 in 15 seconds

Aim

Correct hand hygiene is widely regarded as an important measure to prevent healthcare-associated infections. Guidelines on how to perform hand antisepsis are often inspired by laboratory tests that focus on reproducibility rather than ease of use. These cumbersome recommendations can become barriers to hand hygiene, as optimal user acceptance requires a small rub volume and a short application time with an intuitive rubbing technique. Here we modified the EN 1500 to test the efficacy of hand rubs under more user-friendly conditions, using a highly intuitive rubbing technique in 15 seconds.

Methods

The efficacy of an ethanolic and a propanolic hand rub in inactivating E. coli on the hands of volunteers was tested according to EN 1500 with modifications in rubbing technique and time. Pre-tests were conducted to find a suitable volume for "responsible application", a procedure without clearly defined steps. Finally, 20 volunteers applied both rubs for 15 seconds using 3 mL and "responsible application" and 5 mL using the WHO 6-step technique.

Results

Both hand rubs, ethanolic and propanolic, were non-inferior to an unmodified EN 1500 reference for both application methods, 3 mL with "responsible application" and 5 mL with the WHO 6-step method.

Conclusion

Reducing the complexity of hand rub application can have a positive impact on hand hygiene adherence. With our results showing that antimicrobial efficacy comparable to an unmodified EN 1500 can be achieved in 15 seconds using an intuitive rubbing technique, further barriers to more user-friendly hand rub application have been removed.

Nosocomial outbreak caused by disinfectant-resistant Serratia marcescens in an adult intensive care unit, Hungary, February to March 2022

In 2022, an outbreak with severe bloodstream infections caused by Serratia marcescens occurred in an adult intensive care unit (ICU) in Hungary. Eight cases, five of whom died, were detected. Initial control measures could not stop the outbreak. We conducted a matched case-control study. In univariable analysis, the cases were more likely to be located around one sink in the ICU and had more medical procedures and medications than the controls, however, the multivariable analysis was not conclusive. Isolates from blood cultures of the cases and the ICU environment were closely related by whole genome sequencing and resistant or tolerant against the quaternary ammonium compound surface disinfectant used in the ICU. Thus, S. marcescens was able to survive in the environment despite regular cleaning and disinfection. The hospital replaced the disinfectant with another one, tightened the cleaning protocol and strengthened hand hygiene compliance among the healthcare workers. Together, these control measures have proved effective to prevent new cases. Our results highlight the importance of multidisciplinary outbreak investigations, including environmental sampling, molecular typing and testing for disinfectant resistance.

Rinse, gel, and foam - is there any evidence for a difference in their effectiveness in preventing infections?

BACKGROUND

Following publication of the 2009 World Health Organizations Guidelines for Hand Hygiene in Health Care, a debate has emerged regarding the relative antimicrobial efficacy of the different formats (rinse, gel, foam) of ABHRs and their ability to contribute to reduction of healthcare-associated infections (HAIs).

METHODS

Data regarding the in-vivo antimicrobial efficacy of ABHRs and other factors that likely affect their effectiveness in reducing HAIs were reviewed, and a comprehensive review of studies that reported the effectiveness of each of the three ABHR formats to improve hand hygiene compliance and reduce HAIs was conducted.

RESULTS

The amount of rubbing time it takes for hands to feel dry (dry time) is the major driver of ABHR antimicrobial efficacy. ABHR format is not a major factor, and several studies found that rinse, gel, and foam ABHRs have comparable in-vivo antimicrobial efficacy. Other factors that likely impact the ability of ABHRs to reduce transmission of healthcare-associated pathogens and HAIs include ABHR formulation, the volume applied to hands, aesthetic characteristics, skin tolerance, acceptance by healthcare personnel, and hand hygiene compliance rates. When accompanied by complementary strategies, promoting the use of each of the three ABHR formats has been associated with improvements in hand hygiene compliance rates. A review of 67 studies failed to identify an ABHR format that was significantly more effective in yielding statistically significant reductions in transmission of healthcare-associated pathogens or HAIs.

CONCLUSIONS

Current evidence is insufficient to definitively determine if one ABHR format is more effective in reducing transmission of healthcare-associated pathogens and HAIs. More rigorous studies such as multicenter randomized controlled trials comparing the different formats are needed to establish if one format is significantly more effective in reducing HAIs.

Quality Indicators in Adult Critical Care Medicine

Quality indicators are increasingly used in the intensive care unit (ICU) to compare and improve the quality of delivered healthcare. Numerous indicators have been developed and are related to multiple domains, most importantly patient safety, care timeliness and effectiveness, staff well-being, and patient/family-centered outcomes and satisfaction. In this review, we describe pertinent ICU quality indicators that are related to organizational structure (such as the availability of an intensivist 24/7 and the nurse-to-patient ratio), processes of care (such as ventilator care bundle), and outcomes (such as ICU-acquired infections and standardized mortality rate). We also present an example of a quality improvement project in an ICU indicating the steps taken to attain the desired changes in quality measures.

Current issues in hand hygiene

BACKGROUND

Multiple aspects of hand hygiene have changed in recent years.

METHODS

A PubMed search was conducted to identify recent articles about hand hygiene.

RESULTS

The COVID-19 pandemic caused temporary changes in hand hygiene compliance rates and shortages of alcohol-based hand sanitizers (ABHSs), and in marketing of some products that were ineffective or unsafe. Fortunately, ABHSs are effective against SARS-CoV-2 and other emerging pathogens including Candida auris and mpox. Proper placement, maintenance, and design of ABHS dispensers have gained additional attention. Current evidence suggests that if an adequate volume of ABHS has been applied to hands, personnel must rub their hands together for at least 15 seconds before hands feel dry (dry time), which is the primary driver of antimicrobial efficacy. Accordingly, practical methods of monitoring hand hygiene technique are needed. Direct observation of hand hygiene compliance remains a challenge in many healthcare facilities, generating increased interest in automated hand hygiene monitoring systems (AHHMSs). However, several barriers have hindered widespread adoption of AHHMSs. AHHMSs must be implemented as part of a multimodal improvement program to successfully improve hand hygiene performance rates.

CONCLUSIONS

Remaining gaps in our understanding of hand hygiene warrant continued research into factors impacting hand hygiene practices.

Microbial Community Characterization and Molecular Resistance Monitoring in Geriatric Intensive Care Units in China Using mNGS

Background

Surface pathogens in the ICU pose a global public health threat, especially to elderly patients who are immunocompromised. To detect these pathogens, unbiased methods such as metagenomic next-generation sequencing (mNGS) are increasingly utilized for environmental microbiological surveillance.

Methods

In a six-month study from January to July 2022, we investigated microbial communities in Chinese geriatric ICUs by regularly monitoring multiple surfaces at three-month intervals. Using mNGS sequencing, we analyzed microorganisms present at eight specific locations within the ICU. Additionally, we compared pathogen profiles and drug resistance genes between patient cultures and environmental samples collected during the same period.

Results

The microbial composition remained relatively stable over time, but significant differences in alpha diversities were observed among various surfaces such as floors, hands, pumps, trolleys, and ventilator inlets/outlets. Surfaces with high contact frequency for healthcare workers, including workstations, ventilator panels, trolleys, pumps, and beds, harbored pathogenic microorganisms such as Acinetobacter baumannii, Cutibacterium acnes, Staphylococcus haemolyticus, Pseudomonas aeruginosa, and Enterococcus faecium. Acinetobacter baumannii, particularly the carbapenem-resistant strain (CRAB), was the most frequently identified pathogen in geriatric ICU patients regardless of testing method used. The mNGS approach enabled detection of viruses, fungi, and parasites that are challenging to culture. Additionally, an abundance of drug resistance genes was found in almost all environmental samples.

Conclusion

The microbial composition and abundance in the ICU remained relatively constant over time. The floor exhibited the highest microbial diversity and abundance in the ICU environment. Drug-resistant genes in the ICU environment may migrate between patients. Overall, mNGS is an emerging and powerful tool for microbiological monitoring of the hospital environment.

Current methods for contactless optical patient diagnosis: a systematic review

Many countries around the world face a shortage of medical personnel, leading to work overload or even burnout. This calls for political and scientific solutions to relieve the medical personnel. The measurement of vital signs in hospitals is still predominately carried out manually with traditional contact-based methods, taking over a substantial share of the medical personnel's workload. The introduction of contactless methods for vital sign monitoring (e.g., with a camera) has great potential to relieve the medical personnel. This systematic review's objective is to analyze the state of the art in the field of contactless optical patient diagnosis. This review distinguishes itself from already existing reviews by considering studies that do not only propose the contactless measurement of vital signs but also include an automatic diagnosis of the patient's condition. This means that the included studies incorporate the physician's reasoning and evaluation of vital signs into their algorithms, allowing an automated patient diagnosis. The literature screening of two independent reviewers resulted in a total of five eligible studies. The highest number of studies (three) introduce methods for the risk assessment of infectious diseases, one study introduces a method for the risk assessment of cardiovascular diseases, and one study introduces a method for the diagnosis of obstructive sleep apnea. Overall, high heterogeneity in relevant study parameters is reported among the included studies. The low number of included studies indicates a large research gap and emphasizes the demand for further research on this emerging topic.

Compliance with hand disinfection in the surgical area of an orthopedic university clinic: results of an observational study

Background

Hand hygiene using alcoholic hand rub solution is essential for the prevention of surgical site infections. There are several opportunities for hygienic hand disinfection (termed “hand hygiene” in the following) during immediate pre-, intra- and postoperative orthopedic patient care. However, the level of hand hygiene compliance among surgical and anesthesia staff in this context is unclear. Therefore, we conducted an observational study in operating theatres of an orthopedic university clinic in northern Germany during July and August 2020.

Methods

One trained person directly and comprehensively observed hand hygiene compliance of surgical and anesthesia staff according to the WHO “My 5 moments for hand hygiene” model (WHO-5). In addition to cross-tabulations with Chi² tests, multiple logistic regression models were used to study associations between occupational group, medical specialty, and compliance (both overall and for each WHO-5 indication). Models were adjusted for hand hygiene opportunities being associated with female or male healthcare workers, being located within or outside the operation room, and occurring in adult or pediatric surgery.

Results

In total, 1145 hand hygiene opportunities during 16 surgeries were observed. The overall compliance was 40.8% (95% CI 37.9–43.6%), with a larger difference between surgical versus anesthesia staff (28.4% vs. 46.1%, p < 0.001) than between physicians versus nurses (38.5% vs. 42.9%, p = 0.13). Adjusting for sex, place of observation, and adult versus pediatric operation theatre, logistic regression analyses revealed a significant interaction between medical specialty and occupational group (p < 0.001). In particular, the odds for compliance were higher for anesthesiologists (47.9%) than for surgeons (19.6%) (OR = 4.8, 95% CI 3.0–7.6). In addition, compliance was higher in pediatric surgery (OR = 1.9, 95% CI 1.4–2.6). In general, WHO-5-stratified results were in line with these overall patterns.

Conclusions

Hygienic hand disinfection compliance was approximately 41%. Notably, surgeons performed worse than anesthesiologists did. These results indicate that hand hygiene compliance in orthopedic surgery needs to be improved. Tailored interventions promise to be an appropriate way to address each occupational group’s specific needs.

Hand hygiene compliance by direct observation in physicians and nurses: a systematic review and meta-analysis

BACKGROUND

Direct observation of hand hygiene compliance is the "gold standard" despite limitations and potential for bias. Previous literature highlights poorer hand hygiene compliance amongst physicians than nurses and suggests that covert monitoring may give better compliance estimates than overt monitoring.

AIM

This review aimed to explore differences in compliance between physicians and nurses further, and to analyse if compliance estimates differed when observations were covert rather than overt.

METHODS

A systematic search of databases PubMed, EMBASE, CENTRAL and CINAHL was performed. Experimental or observational studies in hospital settings in high-income countries published in English from 2010 onwards were included if estimates for both physicians and nurses using direct observation were reported. The search yielded 4814 studies, of which 105 were included.

FINDINGS

The weighted pooled compliance rate for nurses was 52% (95% CI 47% to 57%) and for doctors was 45% (95% CI 40% to 49%). Heterogeneity was considerable (I²=99%). The majority of studies were at moderate or high risk of bias. Random-effects meta-analysis of low risk of bias studies suggests higher compliance for nurses than physicians for both overt (difference of 7%, 95% CI for the difference 0.8% to 13.5%, p=0.027) and covert (difference of 7%, 95% CI 3% to 11%, p=0.0002) observation. Considerable heterogeneity was found in all analyses.

CONCLUSION

Wide variability in compliance estimates and differences in the methodological quality of hand hygiene studies were identified. Further research with meta-regression should explore sources of heterogeneity and improve the conduct and reporting of hand hygiene studies.

The impact of activating an empathic focus during COVID19 on healthcare workers motivation for hand hygiene compliance in moments serving the protection of others: a randomized controlled trial study

Aim

The "Five moments of hand hygiene" (World Health Organization 2009) can be classified into moments of hand hygiene before and after patient care. Based on research indicating that hand hygiene compliance differs with regard to moments before and after patient care, this research evaluates the effectiveness of an empathy-based intervention in motivating hand hygiene compliance with regard to moments before patient care which protect vulnerable individuals from contamination and infection.

Subjects and method

An online experiment involving 68 healthcare professionals working at a German hospital during the first wave of the COVID-19 pandemic investigates whether instructing healthcare professionals to consider consequences for others (vs for themselves) if they contracted SARS-CoV-2 promotes hand hygiene compliance referring to moments before (vs after) patient care.

Results

In the condition in which healthcare professionals considered consequences for others if they contracted SARS-CoV-2 (other-focus condition), ratings of importance increased (M = 3.49, SD = 1.30) compared to the condition in which healthcare professionals considered consequences for themselves (M = 2.68, SD = 1.24), F(1,66) = 6.87, p = .011, partη2 = .09. Participants in the other-focus condition reported more intentions to comply with "before moments" in the future (M = 3.34, SD = 1.14) compared to participants in the self-focus condition (M = 2.77, SD = 0.80), F(1,66) = 6.15, p = .016, partη2 = .09.

Conclusion

Results indicate that activating an empathic focus in the context of the current pandemic promotes perceived importance and motivation of healthcare professionals to comply with moments aiming at protecting vulnerable others.

Hand Hygiene Auditing: Is It a Roadway to Improve Adherence to Hand Hygiene Among Hospital Personnel?

Background

Over the years, there has been an increase in hospital-acquired infections (HAIs) among patients in India. One of the main reasons is a lack of compliance with infection control guidelines, such as hand hygiene. So the present study was conducted to determine the compliance of hand hygiene among healthcare workers in a private tertiary care teaching hospital in South India.

Materials and methods

The prospective observational study was carried out between April 2017 and March 2020. Nineteen areas were directly observed for hand hygiene (HH) compliance. At each location, HH audit was conducted for one hour per day for five days per month. HH complete adherence rate (HHCAR) and HH partial adherence rate (HHPAR) were analyzed.

Results

Nine hundred and twenty observation periods were completed during the entire study period. Overall, hand hygiene complete adherence rate was 29.9% (11,981/39,998); partial adherence rate was 45.3% (18,131/39,998) and the non-adherence rate was 24.7% (9886/39,998). A better adherence rate was seen among nurses (44.7%), followed by other staff (33.7%) and doctors (33.04%). Moment-specific adherence rates show almost equal adherence rates of 50.7%, 50.75%, and 50.1%, respectively, for moments 2, 3, and 4, and comparatively low for moments 1 and 5 (48.4% and 47.6%, respectively).

Conclusion

Despite adequate hand hygiene facilities, compliance remains low. Hand hygiene is a bundle care approach that needs to consider factors including healthcare staff, clinical, institutional, environmental, and behavioral changes. Multimodal interventions and multidisciplinary commitment are mandatory for sustained compliance.

Improving hand hygiene practices in two regional hospitals in Kenya using a continuous quality improvement (CQI) approach

Background

Hand hygiene (HH) is central in prevention of health care-associated infections. In low resource settings, models to improve HH compliance are needed. We implemented a continuous quality improvement (CQI) program targeting HH in two hospitals in Kenya.

Objective

To determine the impact of the HH CQI program and identify factors associated with HH compliance between 2018 and 2019.

Methods

A CQI project targeting the improvement of hand hygiene was implemented, including training and mentorship. Data were collected monthly between April 2018 and December 2019 in Thika and Kitale Hospitals. Healthcare workers trained on Infection Prevention and Control (IPC) observed and recorded HH opportunities and subsequent compliance among staff, including nurses, clinicians, and auxiliary staff, using the World Health Organization’s “My Five Moments for Hand Hygiene” tool. Covariates were explored using mixed-effects logistic regression with random department-level intercepts.

Results

Hand hygiene compliance improved from 27% at baseline to 44% after 21 months. Indication/moment for HH was significantly associated with compliance. Adjusting for site, professional category and department, compliance was higher after a moment of body fluid exposure (aOR 1.43, 95% CI 1.17–1.74, p value < 0.001) and lower before an aseptic procedure (aOR 0.12, 95% CI 0.08–0.17, p value < 0.001) compared to after patient contact. Wearing of gloves often replaced proper HH in surgical departments, which although not significant, had lower compliance compared to departments for internal medicine (aOR 0.93, 95% CI 0.85–1.02). Adjusted HH compliance from all quarters improved from baseline, but comparing each quarter to the previous quarter, the improvement fluctuated over time.

Conclusion

Training and mentorship on the importance of HH for all moments is needed to improve overall HH compliance. CQI with regular monitoring and feedback of HH performance can be an effective approach in improving HH compliance in public hospitals in Kenya.

Discordance among Belief, Practice, and the Literature in Infection Prevention in the NICU

This study evaluates practices of infection control in the NICU as compared with the available literature. We aimed to assess providers’ awareness of their institutional policies, how strongly they believed in those policies, the correlation between institution size and policies adopted, years of experience and belief in a policy’s efficacy, and methods employed in the existing literature. An IRB-approved survey was distributed to members of the AAP Neonatal Section. A systematic review of the literature provided the domains of the survey questions. Data was analyzed as appropriate. A total of 364 providers responded. While larger NICUs were more likely to have policies, their providers are less likely to know them. When a policy is in place and it is known, providers believe in the effectiveness of that policy suggesting consensus or, at its worst, groupthink. Ultimately, practice across the US is non-uniform and policies are not always consistent with best available literature. The strength of available literature is adequate enough to provide grade B recommendations in many aspects of infection prevention. A more standardized approach to infection prevention in the NICU would be beneficial and is needed.

A qualitative study of reinforcement workers' perceptions and experiences of working in intensive care during the COVID-19 pandemic: A PsyCOVID-ICU substudy

PURPOSE

During the COVID pandemic, many hospitals had to mobilize reinforcement healthcare workers, especially in intensive care (ICUs). We investigated the perceptions and experiences of reinforcement workers deployed to ICUs, and the impact of deployment on their personal and professional lives.

METHODS

For this qualitative study, a random sample of 30 reinforcement workers was drawn from 4 centres participating in the larger PsyCOVID-ICU study. Individual semi-structured interviews were held, recorded, transcribed and analyzed by thematic analysis.

RESULTS

Thirty interviews were performed from April to May 2021 (22 nurses, 2 anesthesiology nurses, 6 nurses' aides). Average age was 36.8±9.5 years; 7 participants had no ICU experience. Four major themes emerged, namely: (1) Difficulties with integration, especially for those with no ICU experience; (2) lack of training; (3) difficulties with management, notably a feeling of insufficient communication; (4) Mental distress relating to the unusual work and fear of contaminating their entourage.

CONCLUSION

Healthcare workers deployed as reinforcements to ICUs at the height of the pandemic had a unique experience of the crisis, and identified important gaps in organisation and preparation. They also suffered from a marked lack of training, given the stakes in the management of critically ill patients in the ICU.

Characterization of COVID-19 outbreaks in three nursing homes during the first wave in Berlin, Germany

Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) belongs to the coronavirus family and is characterized by its high transmission competence. Elderly COVID-19 patients are at significantly higher risk of severe course of disease and death. Therefore, outbreaks in nursing homes are particularly challenging for facility managers and health authorities. Here, we report three outbreaks of COVID-19 related to nursing homes (NH01.a, NH02 and NH03) with almost 1000 affected individuals during the first COVID-19 wave in Berlin, Germany. The occurrence of cases and the measures taken were analyzed retrospectively. In all three outbreaks, the index persons were nursing home employees or volunteers. Measures taken were quarantine of contacts, close-meshed tests, separation of the affected housing unit, suspension of admission, ban on visiting, and equipping staff with personal protective equipment, of which there was a shortage in Germany at the beginning of the pandemic. A court-ordered quarantine became necessary for three residents of NH01.a due to cognitive disabilities. In total, 61 persons were tested positive for SARS-CoV-2 in NH01.a, ten persons in NH02, and sixteen persons in NH03. Seventeen patients (27.9%) of NH01.a and three patients (18.8%) of NH03 were referred to hospital. Of all confirmed cases, thirteen (21.3%) related to NH01.a and four (25.0%) related to NH03 died as a result of the infection. Besides one 82 year old volunteer, all deceased persons were residents aged between 66 and 98. Our results emphasize the importance of a previously developed containment and cluster strategy for nursing homes. Due to the particular vulnerability of the residents, immediate action, close cooperation and communication between the facility management, residents, visitors and the health authorities are essential in the case of confirmed COVID-19 cases in healthcare facilities.

Perform hand hygiene and the doors will open - the effectiveness of new system implementation on Paediatric Intensive Care Unit visitors' handwashing compliance

Hand hygiene (HH) performance on entering intensive care units (ICUs) is commonly accepted but often inadequately performed. We developed a simple, inexpensive module that connects touchless dispensers of alcohol sanitiser (TDAS) to the automatic doors of a paediatric ICU, and assessed the impact of this intervention on HH compliance of hospital staff and visitors. A prospective observational study was conducted over a 3-week period prior to the intervention, followed by a 4-week period post intervention. HH performance was monitored by a research assistant whose office location enabled direct and video-assisted observation of the ICU entrance. A total of 609 entries to the ICU was recorded. Overall HH performance was 46.9% (92/196) before and 98.5% (406/413) after the intervention. Our findings suggest that HH performance on entering an ICU can be improved via a mechanism that makes operation of an automatic door dependent on use of a TDAS system, and thus contribute to infection control.

What are the predictors of hand hygiene compliance in the intensive care unit? A cross-sectional observational study

Background:

Although appropriate hand hygiene (HH) practices are recognised as the most effective preventative strategy for infection, adherence is suboptimal. Previous studies in intensive care units (ICUs) have found differences in HH compliance between those moments that protect the patient, and those that protect the healthcare provider. However, such studies did not control for other variables known to impact HH compliance.

Aim:

To examine HH among healthcare workers (HCWs) in ICU settings, and identify whether there is a statistical difference in HH compliance between patient-protective and self-protective moments, while controlling for other variables known to influence HH compliance (i.e. professional role, unit and shift time).

Methods:

A cross-sectional observational study was conducted in four ICUs across three Irish hospitals. Compliance was assessed according to the WHO’s ‘five moments for hand hygiene’. HCW professional role, total number of ‘opportunities’ for HH and whether compliance was achieved were recorded.

Results:

A total of 712 HH opportunities were recorded, with an overall compliance rate of 56.9%. Logistic regression analysis revealed that physicians, allied healthcare professionals and auxiliary staff were less likely than nurses to engage in HH. HCWs were more likely to comply during night shifts compared to morning shifts, and with self-protective as compared to patient-protective HH moments.

Conclusion:

The information provided in this study provides a data-driven approach that ICUs can use to tailor HH interventions to where, when and for whom they are most required.

Hand Hygiene, an Update

Hand hygiene by health care personnel is an important measure for preventing health care-associated infections, but adherence rates and technique remain suboptimal. Alcohol-based hand rubs are the preferred method of hand hygiene in most clinical scenarios, are more effective and better tolerated than handwashing, and their use has facilitated improved adherence rates. Obtaining accurate estimates of hand hygiene adherence rates using direct observations of personnel is challenging. Combining automated hand hygiene monitoring systems with direct observations is a promising strategy, and is likely to yield the best estimates of adherence. Greater attention to hand hygiene technique is needed.

Gloves use and possible barriers - an observational study with concluding questionnaire

Aim: The basic assumption of this study was that the use of medical non-sterile gloves represents a barrier to correct hand hygiene behaviour. The aim of this study was to examine this assumption and detect reasons for possible incorrect behaviour. Accordingly, the hypothesis is that peri-glove compliance is lower than hand-disinfection compliance.

Methods: The study involved the direct observation of the use of non-sterile, single-use medical gloves in three different wards of a university hospital. Nursing staff and physicians were observed. After the observation period, the observed persons received a custom-designed questionnaire in order to test their self-assessment, knowledge as well as structural conditions relating to the use of gloves. The results were evaluated and compared with the observation data.

Results: All employees disinfected their hands in 18.6% of cases before and in 65% of cases after the use of non-sterile gloves. Gloves were changed in the event of the indication for hand disinfection/change of gloves in 27.5% of cases. When changing gloves, the employees disinfected their hands in 47.2% of cases. The respondents assessed themselves as being significantly better than the observations revealed. The respondents are aware of the rules about hand disinfection before and after the use of gloves. However, it was less commonly known that gloves are not an absolute barrier to the transmission of bacteria.

Conclusion: Non-sterile single-use gloves seem to be a barrier to hand disinfection. Solutions must be found in order to improve peri-glove compliance, in particular with regard to hand disinfection before and during the wearing of gloves. Alongside the mere transfer of knowledge, the use of non-sterile gloves with regard to the current structural conditions in everyday clinical practice should be critically scrutinised, questioned, tested and developed for the users through precise instructions.

Relationship between hand hygiene behavior and Staphylococcus aureus colonization on cell phones of nurses in the intensive care unit

Background

Healthcare-Associated Infections (HAIs) are infections that often occur in hospitals with Staphylococcus aureus as the primary cause. Staphylococcus aureus is usually found on nurses' hands and easily transferred by contact. Cell phones can be a convenient medium for transmitting bacteria. Accordingly, hand washing is one of the effective ways to prevent the transmission of Staphylococcus aureus.

Objective

This study aimed to determine the relationship between hand hygiene behavior and the colonization of Staphylococcus aureus on cell phones of nurses in the intensive care unit of the academic hospital.

Methods

This was an observational study with a cross-sectional design conducted from December 2019 to January 2020. The observations of hand hygiene behaviors were performed on 37 nurses selected using total sampling. Colonization of bacteria on each nurses' cell phone was calculated by swabbing the cell phones' surface. Colony counting was done using the total plate count method. Spearman Rank test and Mann Whitney test were used for data analysis.

Results

The nurses' hand hygiene behavior was 46.06%. Staphylococcus aureus colonization was found on 18.2% of the nurses' cell phones. However, there was no significant relationship between the nurses' hand hygiene behavior and the colonization of Staphylococcus aureus on their cell phones.

Conclusion

The hand hygiene behavior of nurses was still low, and there was evidence of Staphylococcus aureus colonization on their cell phones. As there was no relationship between the nurses' hand hygiene behavior with the colonization of Staphylococcus aureus on the cell phones, further research is needed to determine if there is an increase or decrease in colonization before and after regular observations.

Compliance measurement and observed influencing factors of hand hygiene based on COVID-19 guidelines in China

BACKGROUND

Higher requirement is put forward in the measurement of hand hygiene (HH) during a pandemic. This study aimed to describe HH compliance measurement and explore observed influencing factors with respect to coronavirus disease 2019 (COVID-19) guidelines in China.

METHODS

Compliance was measured as the percentage of compliant opportunities based on criteria for 17 moments. The criteria for compliance included HH behavior, procedure, duration, hand drying method, and the overall that counts them all. The observed influencing factors included different departments and areas and protection motivation. Descriptive analysis and logistic regression were performed.

RESULTS

The compliance of overall criteria, HH behavior, procedure, duration, and hand drying method were 79.44%, 96.71%, 95.74%, 88.93%, and 88.42%, respectively, which were significantly different from each other (P < .001). Meanwhile, the overall and hand drying method compliance in semi-contaminated areas (odds ratio [OR] = 1.829, P < .001; OR = 2.149, P = .001) and hygienic areas (OR = 1.689, P = .004; OR = 1.959, P = .015) were significantly higher than those in contaminated area. The compliance with HH behavior for the motivation of patient-protection (OR = 0.362, P < .001) was lower than that for the motivation of self-protection.

CONCLUSIONS

HH compliance was firstly measured using different criteria for 17 moments according to COVID-19 guidelines in China. The measurement of HH compliance needs clearer definition and comprehensive practice. Contaminated areas and motivation of patient-protection contribute to lower compliance, which may be addressed by allocating more human resources and increasing supervision and education.

COMPLIANCE TO SAFETY BARRIERS IN THE MEDICATION ADMINISTRATION PROCESS IN PEDIATRICS

ABSTRACT Objective: to investigate the compliance to safety barriers adopted in the preparation and administration of intravenous drugs in Pediatric and Pediatric Intensive Care Units. Method: exploratory, observational descriptive study, conducted with the nursing team of a pediatric intensive care unit and a pediatric clinic of a large public hospital in Belo Horizonte, from August to November 2017. Results: the sample consisted of 334 opportunities to observe the preparation and administration of medications in pediatric patients. Most of the actions were performed by female professionals, nursing technicians and civil servants. The professionals did not perform all the necessary safety barriers in any of the procedures. The hygiene of the preparation site, disinfection of the ampoule, connection, conference of the drug/dose/route administered with the prescription and double checking of the drugs were those that had the lowest compliance. Conclusion: the study highlights the fragility regarding compliance to safety barriers in the preparation and administration of medicines, resulting in a risk to the safety of hospitalized children. Continued education based on good practice is believed to be an important strategy for security.

Hand hygiene compliance in intensive care units: An observational study

Aim

Health care–associated infections along with antibiotic resistance are a leading risk for patient safety in intensive care units. Hygienic hand disinfection is still regarded as the most effective, simplest, and most cost‐effective measure to reduce health care–associated infections. To improve hand hygiene compliance and to prevent health care–associated infections, interventions of the “German Clean Hands Campaign” were implemented in a university hospital.

Methods

Observational single‐center study using direct observation and feedback. Hand hygiene performance was assessed in 12 intensive care units between 2013 and 2017. Linear mixed model regression analyses were used to estimate the compliance trend over time.

Results

In total, 10 315 “my five moments for hand hygiene” were observed. The mean hand hygiene compliance rates increased from 75.1% to 88.6% during the study period, yielding an estimated increase of about 4.5% per year. However, there are differences in compliance between occupational groups (physicians: between 61.2% and 77.1%; nurses: between 80.2% and 90.9%; others: between 61.3% and 82.4%).

Conclusions

After implementation of the “German Clean Hands Campaign” interventions, an overall significant improvement of hand hygiene was detected. Compliance measurements helped to raise awareness among health care professional groups.

What is already known about this topic?

A significantly higher prevalence of infections has been observed in intensive care unit patients compared with patients in other wards.

Hygienic hand disinfection is still regarded as the most effective, simplest, and most cost‐effective measure to reduce health care–associated infections.

Low hand hygiene rates in intensive care units are a major problem for patient safety.

What is already known about this topic?

Implementation of the “German Clean Hands Campaign” showed continuous improvement in hand hygiene for all health care professionals in intensive care units over a period of 5 years.

There are differences in compliance rates between health care profession and intensive care unit types.

Pediatric intensive care units had the highest hand hygiene compliance rates.

The implications of this paper:

Overall, hand hygiene compliance in intensive care units increased over a period of 5 years after continuous campaigning, training, observation, compliance measurements, and direct feedback.

It is necessary to raise awareness for hand hygiene in a repetitive manner within all health care professional groups now and in the future.

Because of the differences in compliance rates between health care professionals, more tailored and evidence‐based interventions should be implemented.

The effect of training and awareness of subtle control on the frequency of hand hygiene among intensive care unit nurses

Objective

This study aimed to determine the effect of awareness of subtle control after training on the hand hygiene compliance among nurses in intensive care units (ICUs). The study was conducted in two ICUs of a trauma center in Shiraz, Iran on 48 nurses. The nurses of one ICU were randomly allocated to the intervention and the nurses of the other ICU were allocated to the control group. All nurses were trained on hand hygiene. Then a fake closed camera television (CCTV) was visibly installed in the intervention group’s ICU, while the nurses were aware of it. The degree of compliance with hand hygiene was observed in both groups before and after the intervention. Data were gathered using a checklist based on the World Health Organization hand hygiene protocol and analyzed using SPSS 16 and the Chi square, Wilcoxon, Mann–Whitney U, and Independent T-tests, were performed.

Results

The mean percentage of hand hygiene compliance in the intervention group after the intervention was significantly higher than before the intervention (p < 0.001). Additionally, the changes in the mean percentage of the intervention group was significantly higher than that for the control group (p = 0.001). The findings showed that a fake CCTV after training, installed in ICUs, can improve hand hygiene compliance.

Nursing preference for alcohol-based hand rub volume

Background:

The effectiveness of alcohol-based hand rub (ABHR) is correlated with drying time, which depends on the volume applied. Evidence suggests that there is considerable variation in the amount of ABHR used by healthcare providers.

Objective:

We sought to identify the volume of ABHR preferred for use by nurses.

Methods:

A prospective observation study was performed in 8 units at a tertiary-care hospital. Nurses were provided pocket-sized ABHR bottles with caps to record each bottle opening. Nurses were instructed to use the volume of ABHR they felt was best. The average ABHR volume used per hand hygiene event was calculated using cap data and changes in bottle mass.

Results:

In total, 53 nurses participated and 140 nurse shifts were analyzed. The average ABHR dose was 1.09 mL. This value was greater for non-ICU nurses (1.18 mL) than ICU nurses (0.96 mL), but this difference was not significant. We detected no significant association between hand surface area and preferred average dose volume. The ABHR dose volume was 0.006 mL less per use as the number of applications per shift increased (P = .007).

Conclusions:

The average dose of ABHR used was similar to the dose provided by the hospital’s automated dispensers, which deliver 1.1 mL per dose. The volume of ABHR dose was inversely correlated with the number of applications of ABHR per shift and was not correlated with hand size. Further research to understand differences and drivers of ABHR volume preferences and whether automated ABHR dosing may create a risk for people with larger hands is warranted.

Current issues in hand hygiene

Although substantial improvements in hand hygiene practices have occurred in recent years, many health care facilities continue to encounter challenges in achieving and maintaining high levels of hand hygiene compliance. Issues of current interest include the optimum dose of alcohol-based handrub (ABHR) that should be applied, the impact of hand size and alcohol-based handrub dry times have on efficacy, and ideal hand hygiene technique. There is a need to determine which additional promotional activities can augment improvements in hand hygiene that are achieved by implementing the multimodal improvement strategy recommended by the World Health Organization. Monitoring hand hygiene performance and providing personnel with feedback on their performance are essential elements of successful improvement programs. Further research is needed to establish the most effective methods of providing feedback. Additional studies are needed to optimize strategies for performing direct observation of hand hygiene compliance, and to determine the role of supplementing direct observations using automated monitoring systems.

Self-disinfecting surfaces and infection control

According to World Health Organization, every year in the European Union, 4 million patients acquire a healthcare associated infection. Even though some microorganisms represent no threat to healthy people, hospitals harbor different levels of immunocompetent individuals, namely patients receiving immunosuppressors, with previous infections, or those with extremes of age (young children and elderly), requiring the implementation of effective control measures. Public spaces have also been found an important source of infectious disease outbreaks due to poor or none infection control measures applied. In both places, surfaces play a major role on microorganisms' propagation, yet they are very often neglected, with very few guidelines about efficient cleaning measures and microbiological assessment available. To overcome surface contamination problems, new strategies are being designed to limit the microorganisms' ability to survive over surfaces and materials. Surface modification and/or functionalization to prevent contamination is a hot-topic of research and several different approaches have been developed lately. Surfaces with anti-adhesive properties, with incorporated antimicrobial substances or modified with biological active metals are some of the strategies recently proposed. This review intends to summarize the problems associated with contaminated surfaces and their importance on infection spreading, and to present some of the strategies developed to prevent this public health problem, namely some already being commercialized.

Impact of psychologically tailored hand hygiene interventions on nosocomial infections with multidrug-resistant organisms: results of the cluster-randomized controlled trial PSYGIENE

Background

Professional hand hygiene compliance represents a multifaceted behaviour with various determinants. Thus, it has been proposed to apply psychological frameworks of behaviour change to its promotion. However, randomized controlled trials of such approaches, which also assess nosocomial infections (NIs), are rare. This study analyses data of the PSYGIENE-trial (PSYchological optimized hand hyGIENE promotion), which has shown improvements in compliance after interventions tailored based on the Health Action Process Approach (HAPA), on rates of NIs with multidrug-resistant organisms (MDROs).

Methods

A parallel-group cluster-randomized controlled trial was conducted on all 10 intensive care units and two hematopoietic stem cell transplantation units at Hannover Medical School, a German tertiary care hospital. Educational training sessions for physicians and nurses (individual-level intervention) and feedback discussions with clinical managers and head nurses (cluster-level) were implemented in 2013. In the “Tailoring”-arm (n = 6 wards), interventions were tailored based on HAPA-components, which were empirically assessed and addressed by behaviour change techniques. As active controls, n = 6 wards received untailored educational sessions of the local “Clean Care is Safer Care”-campaign (Aktion Saubere Hände: “ASH”-arm). From 2013 to 2015 compliance was assessed by observation following the World Health Organization, while alcohol-based hand rub usage (AHRU) and NIs with multidrug-resistant gram-negative bacteria, Methicillin-resistant Staphylococcus aureus or Vancomycin-resistant Enterococcus were assessed following national surveillance protocols. Data were analysed at cluster-level.

Results

In the “Tailoring”-arm, interventions led to a decrease of 0.497 MDRO-infections per 1000 inpatient days from 2013 to 2015 (p = 0.015). This trend was not found in the “ASH”-arm (− 0 . 022 infections; p = 0.899). These patterns corresponded inversely to the trends in compliance but not in AHRU.

Conclusions

While interventions tailored based on the HAPA-model did not lead to a significantly lower incidence rate of MDRO-infections compared to control wards, a significant reduction, compared to baseline, was found in the second follow-up year in the “Tailoring”- but not the "ASH"-arm. This indicates that HAPA-tailored hand hygiene interventions may contribute to the prevention of NIs with MDRO. Further research should focus on addressing compliance by interventions tailored not only to wards, but also leaders, teams, and individuals.

Strategies to improve hand hygiene compliance among healthcare workers in adult intensive care units: a mini systematic review

BACKGROUND

Hand hygiene compliance among healthcare workers (HCWs) in intensive care units (ICUs) is disconcertingly low.

AIM

To identify the effective intervention(s) for increasing HH compliance among HCWs in adult ICUs.

METHODS

Two major electronic databases, OVID Medline and CINAHL, were searched by using a combination of MeSH terms and text words (e.g. hand hygiene, hand washing, compliance, adher*, improve*, develop* and intensive care unit) for relevant articles. This was supplemented by Google Scholar and hand searching of included bibliographies. Data from identified articles were then abstracted, quality-assessed, and combined into a summary effect.

FINDINGS

Of 89 titles and abstracts that were identified, 14 articles were finally included. Overall study quality was good. However, variations in design, setting, sample size, and intervention(s) tested precluded a meta-analysis; hence a narrative synthesis was conducted. The interventions included education, observation, provision of supplies, improving access and directive support; tested singly or in combination; resulted in positive outcomes in all but one study. A combination of administrative support, 'supplies', education and training, reminders, surveillance, and performance feedback raised the compliance from a baseline of 51.5% to a record 80.1%; but no set of intervention(s) could improve the compliance to the desired near-100% level.

CONCLUSION

Available data suggest that multi-modal interventions are effective in raising the compliance to a 'plateau' level but not up to the desired standard. Methodologically appropriate trials of combined interventions could enhance the evidence about interventions to improve hand hygiene compliance among ICU staff.

Effectiveness of Hygienic Hand Washing Training on Hand Washing Practices and Knowledge: A Nonrandomized Quasi-Experimental Design

Nurses undertake important responsibilities in patient care and the prevention of hospital-acquired infections. However, adherence to hand hygiene practices among nurses has been reported to be low. This study aims to evaluate the effectiveness of hygienic hand washing training on hand washing practices and knowledge. The study design was a nonrandomized, quasi-experimental study, with pretest-posttest for one group. Pre- and postobservations were also conducted using an observation form on any 5 workdays to evaluate the effectiveness of hygienic hand washing training on hand washing practices. The study was conducted with 63 nurses working at a hospital in Istanbul. Hand Hygiene Knowledge Form scores after hygienic hand washing training were higher than the pretraining scores. The number of the nurses' hand hygiene actions after hand hygiene training increased significantly compared with that before training. The results indicate that training in proper hand washing techniques and hygienic hand washing practices positively affects the knowledge level of nurses and their hand washing behavior.

Differences in psychosocial determinants of hand hygiene between health care professional groups: Insights from a mixed-methods analysis

BACKGROUND

Good hand hygiene (HH) prevents health care-associated infections. We compared psychosocial and organizational factors associated with HH compliance and perceived need for improvement among physicians, nurses, and allied health professionals (AHPs).

METHODS

We conducted a mixed-methods study in a 1,600-bed adult tertiary-care hospital in Singapore. Seven focus group discussions were conducted and data were analyzed using thematic analysis. The subsequent cross-sectional survey involved 1,064 staff members. Principal components analysis was performed to derive the latent factor structure that was applied in multivariable analyses.

RESULTS

All staff members acknowledged that HH was an integral part of their work, but were noncompliant due to competing priorities. Physicians were forgetful but appreciated reminders. Nurses were intrinsically motivated for HH. After adjusting for gender, staff category, seniority, and dermatitis history, having positive knowledge-attitudes-behaviors (odds ratio [OR], 1.44; 95% confidence interval [CI], 1.23-1.69), personal motivators-enablers (OR, 1.60; 95% CI, 1.38-1.86), and emotional motivators (OR, 1.62; 95% CI 1.40-1.88) were positively associated with good HH compliance. Women (OR, 3.91; 95% CI, 1.37-11.11), seniors (OR, 2.88; 95% CI, 1.08-7.68), nurses (OR, 4.05; 95% CI, 1.51-10.87), and staff with personal motivators-enablers for HH (OR, 1.60; 95% CI, 1.08-2.37) were more likely to perceive a need for improvement.

CONCLUSIONS

Factors influencing self-reported HH differed between health care professional groups. Group-specific interventions are needed to improve compliance.

Changing the paradigm: messages for hand hygiene education and audit from cluster analysis

BACKGROUND

Hand hygiene is considered to be the foremost infection prevention measure. How healthcare workers accept and make sense of the hand hygiene message is likely to contribute to the success and sustainability of initiatives to improve performance, which is often poor.

METHODS

A survey of nurses in critical care units in three National Health Service trusts in England was undertaken to explore opinions about hand hygiene, use of alcohol hand rubs, audit with performance feedback, and other key hand-hygiene-related issues. Data were analysed descriptively and subjected to cluster analysis.

RESULTS

Three main clusters of opinion were visualized, each forming a significant group: positive attitudes, pragmatism and scepticism. A smaller cluster suggested possible guilt about ability to perform hand hygiene.

CONCLUSION

Cluster analysis identified previously unsuspected constellations of beliefs about hand hygiene that offer a plausible explanation for behaviour. Healthcare workers might respond to education and audit differently according to these beliefs. Those holding predominantly positive opinions might comply with hand hygiene policy and perform well as infection prevention link nurses and champions. Those holding pragmatic attitudes are likely to respond favourably to the need for professional behaviour and need to protect themselves from infection. Greater persuasion may be needed to encourage those who are sceptical about the importance of hand hygiene to comply with guidelines. Interventions to increase compliance should be sufficiently broad in scope to tackle different beliefs. Alternatively, cluster analysis of hand hygiene beliefs could be used to identify the most effective educational and monitoring strategies for a particular clinical setting.

Preventing Transmission of Multidrug-Resistant Pathogens in the Intensive Care Unit

Infection control in the intensive care unit (ICU) has seen many advances, including rapid molecular screening tests for resistant organisms and chlorhexidine use in daily baths. Although these developments advance the cause of infection prevention, compliance with some of the basic measures remains elusive. Hand hygiene, antimicrobial stewardship, and reduction in device use remain the low-technology interventions that could have a major impact on nosocomial transmission of antimicrobial-resistant organisms. Although continued research is needed on new and old ways of preventing nosocomial infections, ICU staff must persevere in improving adherence with the measures that are known to be effective.

Giving the tap the elbow? An observational study

BACKGROUND

Handwashing is viewed as the most important barrier to cross-infection. Incorrect use of clinical handwash basins may lead to cross-infection either from contaminated water or due to failure to decontaminate hands. Elbow-operated taps used correctly prevent recontamination of hands during operation. Many elbow-operated taps are installed incorrectly, with the handle flush with the back panel, making it difficult to open using the elbow.

AIM

To determine the effect of altering the angle of the handle of elbow-operated taps on handwashing technique.

METHODS

An observational study was conducted using two rooms; in one the handles of the elbow-operated taps were flush with the inspection panel behind, and in the other they were set at 35°.

FINDINGS

Thirty-five staff members washed their hands in both rooms. Hands were used to turn on the taps in 97% of instances. In 57% of washes hands were recontaminated when used to turn the tap off. Only six individuals consistently used their elbows to turn outlets off. Surprisingly, more individuals used their elbows to operate taps whose handles were flush with the inspection panel behind.

CONCLUSION

Greater emphasis needs to be placed on correct use of elbow-operated outlets. The decision to use elbow- or sensor-operated outlets is not clear-cut, as each has pros and cons. There is much room for improvement in design and standardization of handwash basins. Given the importance of handwashing it is surprising that these gaps exist.
