Italian National Surveillance of Alcohol-Based Hand Rub Consumption in a Healthcare Setting-A Three-Year Analysis: 2020-2022.

Background/Objectives: Hand hygiene (HH) is pivotal in mitigating infectious disease transmission and enhancing public health outcomes. This study focuses on detailing the national surveillance system for alcohol-based hand rub (ABHR) consumption in healthcare facilities across Italy, presenting results from a comprehensive three-year evaluation period, from 2020 to 2022. It aims to delineate this surveillance system and report on ABHR consumption trends in various Regions/Autonomous Provinces (Rs/APs). Methods: ABHR consumption data, collected through the ABHR Italian national surveillance system, coordinated by the Istituto Superiore di Sanità (ISS), were analyzed. Statistical methods, e.g., the Mann-Whitney test, were used to assess trends in ABHR consumption, expressed in liters per 1000 patient days (L/1000PD). Results: The results show significant variation in ABHR consumption across Rs/APs and over the years studied. National median ABHR consumption decreased from 2020 to 2022, with a significant reduction from a median of 24.5 L/1000PD in 2020 to 20.4 L/1000PD in 2021 and 15.6 L/1000PD in 2022. Conclusions: The decline in ABHR consumption raises concerns about the ongoing adherence to HH practices in Italian healthcare settings. This underscores the essential role that systematic ABHR monitoring and improved surveillance play in enhancing HH compliance, suggesting that sustained and strategic efforts are fundamental to uphold high standards of hygiene and to effectively respond to fluctuating ABHR usage trends over time. Further research is needed to explore barriers to effective ABHR use and to develop targeted strategies to improve HH practices.

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.

PASQUALE - A long-term partnership to improve hand hygiene and capacity building in infection prevention and control in the Faranah region of Guinea.

Across the globe, hand hygiene (HH) is promoted to fight the spread of healthcare associated infections. Despite multiple ongoing HH campaigns and projects, the healthcare associated infection rates remain high especially in low- and middle-income countries. In the narrative overview presented here, we aim to share objectives, framework, successes and challenges of our long-term partnership in Guinea to offer guidance for other projects aiming to sustainably improve HH.

Validation of a hand hygiene visual feedback system to improve compliance with drying time of alcohol-based hand rub in a neonatal intensive care unit: the Incubator Traffic Light system.

BACKGROUND: Compliance with the recommended 30 s drying time of alcohol-based hand rub (ABHR) is often suboptimal. To increase hand hygiene compliance at a neonatal intensive care unit (NICU), we installed an Incubator Traffic Light (ITL) system which shows 'green light' to open incubator doors after the recommended drying time. AIM: To measure the impact of this visual feedback system on NICU healthcare professionals' compliance with the recommended ABHR drying time. METHODS: Ten traffic light systems were installed on incubators at a NICU, five of which provided visual feedback, and five, serving as a control group, did not provide visual feedback. During a two-month period, the systems measured drying time between the moment of dispensing ABHR and opening the incubator's doors. The drying times of the incubators were compared with and without feedback. FINDINGS: Of the 6422 recorded hand hygiene events, 658 were valid for data analysis. Compliance with correct drying time reached 75% (N = 397/526) for incubators equipped with visual feedback versus 36% (N = 48/132; P < 0.0001) for incubators lacking this feature. CONCLUSION: The ITL improves compliance with the recommended 30 s ABHR drying time in a NICU setting.

Acceptability and tolerability of alcohol-based hand rubs among health workers and concessionaires in Malaysia during the COVID pandemic: a hospital-wide cross-sectional study using a modified WHO protocol.

This study evaluated the acceptability and tolerability of three alcohol-based hand rubs (ABHRs) at Sarawak General Hospital, Malaysia. Conducted from 12-26 November 2021 using a modified WHO Protocol, it involved a survey among health workers and concessionaires, with a 35% response rate (1,598 of 4,628 participants). The majority were nurses (60.8%), with the medical division most represented (28.4%). Most respondents (93.2%) used ABHRs at least five days a week and found them easily accessible (72.3%). Product B was the preferred ABHR (65%), primarily for its color and fragrance, surpassing WHO's 50% approval rate in these aspects. However, no other product features met WHO criteria. There were no significant differences in self-reported skin tolerability across the products, and none achieved overall WHO approval. These results offer important insights for ABHR selection in developing countries and highlight the value of the WHO Protocol in assessing product acceptability and tolerability.

A comparative study on the effect of alcohol-based hand sanitizers in spray and gel formulation on the skin: A prospective, randomised, crossover trial.

BACKGROUND: Many formulations of Alcohol-based hand rubs (ABHRs), such as liquid, gel, and spray have been developed and used for preventing infections. This study aimed to compare skin irritation from using ABHRs in gel and spray formulations. METHOD: This was a prospective, randomised, crossover trial conducted to investigate the effect of skin irritation caused by ABHRs in gel compared to spray formulation after 21 days of using each formulation. Clinical outcomes were assessed using subjective Larson's skin assessment score and Frosch and Kligman observer skin assessment score, as well as bioengineering measures: transepidermal water loss (TEWL) and skin capacitance on days 3, 7, 14, and 21. RESULTS: Among 38 participants, both formulations showed no significant change in clinical scores and skin capacitance during the study. However, TEWL increased significantly from baseline on day 3 (p = 0.029) for the spray formulation and on day 21 (p = 0.019) for the gel formulation, with no statistically significant difference between the formulations (p = 0.46). CONCLUSION: Our research supports the safety of gel and spray ABHRs for regular use, with the only potential issue being mild skin irritation. For those with sensitive skin, the gel formulation is preferable.

Using patients' observations to evaluate healthcare workers' alcohol-based hand rub with Pulpe'friction audits: a promising approach?

Background: Hand hygiene plays an important role in the transmission of nosocomial infections from healthcare workers (HCW) to patients. Patients could play a key role in improving hand hygiene by sharing their experience of the HCW's practices. Already in 2019, the French national mission of transversal support for actions to prevent healthcare-associated infections proposed the national "Pulpe'friction" audit, to assess HCW's reported practices, social representations, and barriers to using alcohol-based hand rubs (ABHR). This audit consisted of a positive discussion between an auditor and the HCW as well as patients, which led the HCW to declare their real practices and the barriers they faced in the field and the patients to report about the HCW's ABHR practices and the information they received about when they should perform hand hygiene. Objective: To assess whether an association existed between HCW's reported ABHR compliance and patients' declarations about HCW's compliance in the Pulpe'friction audit data. Methods: Data from Pulpe'friction were collected from 1st January to 31st December 2019, before the COVID-19 pandemic. Mixed linear models were performed to analyze the association between self-reporting by HCW and patients, regarding hand rubs performed by HCW prior to patient care. Results: There was a positive association between patients' observations and HCW's declared practices regarding the frequency of with which professionals performed hand rubs before patient contact. This indicates that professional and patient statements show the same tendency. The positive association was found in hospitals for patients under 45 and over 64 years old and for paramedics, but not for physicians and not in nursing homes or long-term care facilities. Patients felt more motivated to observe and evaluate HCWs' practices if they had received information about how to correctly wash their hands. Conclusion: Patients agreed to be involved in the evaluation or professional practices. The patients' observations were positively associated with HCWs reports. New indicators taking patients' observations into account could be interesting.

Factors associated with better alcohol hand rub in 2020. Results from the French national audit "Pulpe'friction".

Background: The application of alcohol-based hand rub on hands (ABHR) can prevent the transmission of microorganisms. But, in some situations the practices remain perfectible. Aim: The aim of this study was to assess the self-reported ABHR practices of healthcare workers (HCWs) and to identify the factors associated with better ABHR compliance. Methods: A cross-sectional study was conducted using the French national "Pulpe'friction" audit, from 1st January 2020 to 31st December 2020, in healthcare facilities and social welfare facilities in France. Data were analyzed using descriptive statistics and multivariate logistic regression models. Results: Of the 6769 HCWs, the average ABHR compliance was 75% "before patient contact," 95% "before an invasive technique," 86% "after patient contact," and 79% "after contact with patient surroundings." The main reported barriers were the availability, the discomfort and the harmfulness of the product. The factors significantly associated with a better compliance were the individual importance given to hand hygiene (HH); working in a healthcare facility, except in the situation "before an invasive technique"; medical profession "after patient contact"; paramedical profession "after contact with patient surroundings." Discussion: These results call for national actions to fight the most reported barriers and raise awareness on the importance of HH, especially before touching the patient.

Have Hand Hygiene Practices in Two Tertiary Care Hospitals, Freetown, Sierra Leone, Improved in 2023 following Operational Research in 2021?

In 2021, an operational research study in two tertiary hospitals in Freetown showed poor hand hygiene compliance. Recommended actions were taken to improve the situation. Between February-April 2023, a cross-sectional study was conducted in the same two hospitals using the World Health Organization hand hygiene tool to assess and compare hand hygiene compliance with that observed between June-August 2021. In Connaught hospital, overall hand hygiene compliance improved from 51% to 60% (p < 0.001), and this applied to both handwash actions with soap and water and alcohol-based hand rub. Significant improvements were found in all hospital departments and amongst all healthcare worker cadres. In 34 Military Hospital (34MH), overall hand hygiene compliance decreased from 40% to 32% (p < 0.001), with significant decreases observed in all departments and amongst nurses and nursing students. The improvements in Connaught Hospital were probably because of more hand hygiene reminders, better handwash infrastructure and more frequent supervision assessments, compared with 34MH where interventions were less well applied, possibly due to the extensive hospital reconstruction at the time. In conclusion, recommendations from operational research in 2021 contributed towards the improved distribution of hand hygiene reminders, better handwash infrastructure and frequent supervision assessments, which possibly led to improved hand hygiene compliance in one of the two hospitals. These actions need to be strengthened, scaled-up and guided by ongoing operational research to promote good hand hygiene practices elsewhere in the country.

A cluster randomised trial to evaluate the effectiveness of household alcohol-based hand rub for the prevention of sepsis, diarrhoea, and pneumonia in Ugandan infants (the BabyGel trial): a study protocol.

BACKGROUND: Infections are one of the leading causes of death in the neonatal period. This trial aims to evaluate if the provision of alcohol-based hand rub (ABHR) to pregnant women for postnatal household use prevents severe infections (including sepsis, diarrhoea, pneumonia, or death) among infants during the first three postnatal months. METHODS: Through a cluster-randomised trial in eastern Uganda, 72 clusters are randomised in a 2-arm design with rural villages as units of randomisation. We estimate to include a total of 5932 pregnant women at 34 weeks of gestation. All women and infants in the study are receiving standard antenatal and postnatal care. Women in the intervention group additionally receive six litres of ABHR and training on its use. Research midwives conduct follow-up visits at participants' homes on days 1, 7, 28, 42, and 90 after birth and telephone calls on days 14, 48, and 60 to assess the mother and infant for study outcomes. Primary analyses will be by intention to treat. DISCUSSION: This study will provide evidence on the effectiveness of a locally available and low-cost intervention in preventing neonatal sepsis and early infant infections. If ABHR is found effective, it could be implemented by adding it to birthing kits. TRIAL REGISTRATION: Pan African Clinical Trial Registry, PACTR202004705649428.

Effect of Optimal Alcohol-Based Hand Rub among Nurse Students Compared with Everyday Practice among Random Adults; Can Water-Based Hand Rub Combined with a Hand Dryer Machine Be an Alternative to Remove E. coli Contamination from Hands?

Efficient hand hygiene is essential for preventing the transmission of microorganisms. Alcohol-based hand rub (ABHR) is a recommended method. We compared health personnel (skilled nurse students) with random adults to study the effect of an ABHR procedure. A water-based hand rub (WBHR) procedure, using running tap water and a hand-drying machine, was also investigated. The study included 27 nurse students and 26 random adults. Hands were contaminated with Escherichia coli, and concentrations of colony forming units (CFU/mL) were determined before and after ABHR or WBHR. Concentrations after ABHR were 1537 CFU/mL (nurse students) and 13,508 CFU/mL (random adults) (p < 0.001). One-third of participants reported skin irritation from daily ABHR. Concentrations after WBHR were 41 CFU/mL (nurse students) and 115 CFU/mL (random adults) (p < 0.011). The majority of participants (88.5%) preferred the WBHR method. Results from 50 air samples from filtered air from the hand dryer outlet showed no CFU in 47 samples. A significant difference between the two groups was shown for the ABHR method, indicating that training skills are important for efficient hand hygiene. Surprisingly, the WBHR method seemed to have a significant effect in largely removing transient bacteria from hands.

Establishment of District-Led Production of WHO-Recommended Alcohol-based Hand Rub (ABHR) during the COVID-19 Pandemic: A Model for Improving Access to ABHR during Health Emergencies.

In response to the COVID-19 pandemic, we established and sustained local production of alcohol-based handrub (ABHR) at district scale for healthcare facilities and community, public locations in four districts in Uganda. District officials provided space and staff for production units. The project renovated space for production, trained staff on ABHR production, and transported ABHR to key locations. The production officer conducted internal ABHR quality assessments while trained district health inspectors conducted external quality assessments prior to distribution. Information, education, and communication materials accompanied ABHR distribution. Onsite ABHR consumption was monitored by site staff using stock cards. On average, it took 11 days (range: 8-14) and 5,760 USD (range: 4,400-7,710) to set up a production unit. From March-December 2021, 21,600L of quality-controlled ABHR were produced for 111 healthcare facilities and community locations at an average cost of 4.30 USD/L (range: 3.50-5.76). All ABHR passed both internal and external quality control (average ethanol concentration of 80%, range: 78-81%). This case study demonstrated that establishing centralized, local production of quality-controlled, affordable ABHR at a district-wide scale is feasible and strengthens the ability of healthcare workers and community locations to access and use ABHR during infectious disease outbreaks in low-resource countries.

Individual and household risk factors for COVID-19 infection among household members of COVID-19 patients in home-based care in western Uganda, 2020.

Objective: To investigate factors associated with COVID-19 among household members of patients in home-based care (HBC) in western Uganda. Methods: We conducted a case-control and cohort study. Cases were reverse transcriptase-polymerase chain reaction-confirmed SARS-CoV-2 diagnosed 1-30 November 2020 among persons in HBC in Kasese or Kabarole districts. We compared 78 case-households (≥1 secondary case) with 59 control-households (no secondary cases). The cohort included all case-household members. Data were captured by in-person questionnaire. We used bivariate regression to calculate odds and risk ratios. Results: Case-households were larger than control-households (mean 5.8 vs 4.3 members, P<0.0001). Having ≥1 household member per room (adjusted odds ratio (aOR)=4.5, 95% CI 2.0-9.9), symptom development (aOR=2.3, 95% CI 1.1-5.0), or interaction with primary case-patient (aOR=4.6, 95% CI 1.4-14.7) increased odds of case-household status. Households assessed for suitability for HBC reduced odds of case-household status (aOR=0.4, 95% CI=0.2-0.8). Interacting with a primary case-patient increased the risk of individual infection among household members (adjusted risk ratio=1.7, 95% CI 1.1-2.8). Conclusion: Household and individual factors influence secondary infection risk in HBC. Decisions about HBC should be made with these in mind.

Knowledge, Attitudes, and Perceptions Towards Hand Hygiene of Optometry Students Pre- and Peri-COVID-19 at a Tertiary Institution in Johannesburg, South Africa.

Purpose: Limited research has been completed relating to the knowledge, attitudes and practices (KAP) towards hand hygiene in optometry. The necessity of identifying possible gaps in the cycle of the optometric examination that may have an impact on standard hygiene practices is essential, especially seen in the context of the COVID-19 pandemic. The purpose of the study was to determine if optometry students' KAP towards hand hygiene changed pre- and peri-COVID-19 to minimize the risk of possible infection it may have for their patients, family, and themselves. Patients and Methods: A cross-sectional purposeful sample study was completed among optometry students at a training institution in Johannesburg, South Africa, pre- (2019) and peri-COVID-19 (2022). The WHO hand hygiene knowledge and perception questionnaires for health care workers were adapted and used in the current study. Statistical analyses were performed to test for significant changes between the two groups. Results: There was a significant change (p < 0.01) in the use of alcohol-based hand rub (ABHR) in 2022 (87.2%) compared to 2019 (46.5%), although only 41% of students peri-COVID-19 (2022), were aware that a minimum of 20 seconds is required to effectively clean hands. Students, both pre-COVID-19 (63.8%) and peri-COVID-19 (81.8%) perceived performing a hand hygiene regime during an optometric examination to be problematic. A significant peri-COVID-19 (2022) change in perception (p < 0.01) regarding the importance of completing required hand hygiene practices in front of a patient during examination was seen. Conclusion: The COVID-19 pandemic provided a unique opportunity to research a possible change in KAP towards hand hygiene practices in optometry students that have not been investigated before. Students were more aware of the impact of hand hygiene practices and the perception thereof, especially by patients and fellow students during the peri-COVID-19 (2022) period. An important finding was the difficulty that students experienced to perform a hand hygiene regime during an optometric examination.

Comparison of two alcohol hand rubbing techniques regarding hand surface coverage among hospital workers: a quasi-randomized controlled trial.

BACKGROUND: The adapted 6-step without interlock (A6Sw/oI) hand rub technique, commonly practiced in Japan, adds the "wrist" but omits the "interlock" step compared to the WHO 6-step technique (WHO6S). The first objective of this study was to assess the differences of the two techniques regarding surface coverage. The second objective was to analyze the coverage differences between hand sizes. METHODS: Hospital workers went under stratified quasi-randomization by glove size. The overall mean coverage, and the coverage of the sections of the hands were evaluated by fluorescent dye-based coverage assessment using a digital device with artificial intelligence technology. RESULTS: Total of 427 workers were randomly allocated to WHO6S (N = 215) or the A6Sw/oI (N = 212). The overall mean dorsum coverage by WHO6S and A6Sw/oI was 90.6% versus 88.4% (p < 0.01), and the percentage of the participants with insufficient coverage of the backs of the four fingers ranged from 0.0-7.4% versus 28.2-51.4% (p < 0.001). Dorsum coverage varied largely between hand size for both techniques, and significant differences were found between small and large hands. CONCLUSION: The WHO6S was superior to the locally adapted technique regarding hand surface coverage. Hand size should be considered when assessing coverage differences between procedures. No trial registrations or fundings.

A multi-centre study of the effects of direct observation of hand hygiene practices on alcohol-based handrub consumption.

Introduction: The World Health Organization recommends monitoring alcohol-based handrub (ABHR) consumption and direct observation of hand hygiene practices to ensure compliance. In Japan monitoring of ABHR consumption is widely performed. However, direct observation is not common, particularly in small facilities and non-acute-care facilities. Hence, the current study aimed to evaluate the longitudinal effects of direct observation of hand hygiene practices and monitoring of ABHR consumption with provision of feedback to healthcare personnel on ABHR consumption and hand hygiene compliance. Methods: We conducted a 4-year prospective intervention study. Monitoring of ABHR consumption and direct observation of hand hygiene practices with monthly feedback to healthcare personnel was implemented in 17 facilities. These consisted of 11 acute-care facilities of varying sizes and six non-acute-care facilities. A generalized linear mixed model analysis was performed to assess factors associated with ABHR consumption. Results: All facilities implemented ABHR consumption monitoring within one month of starting the study. However, the mean time required to implement direct observation of hand hygiene practices was 24.7 (±19.1) months. The ABHR consumption increased significantly (P<0.0001) in all medical facilities after implementing the direct observation. Multivariable regression analysis showed the hospital ward type, duration of ABHR consumption monitoring, and duration of direct observation of hand hygiene practices were independently associated with ABHR consumption. Conclusions: Direct observation of hand hygiene practices with feedback should be implemented more widely in combination with ABHR consumption monitoring to help increase hand hygiene compliance.

Identifying Targets for Antibiotic Use for the Management of Carbapenem-Resistant Acinetobacter baumannii (CRAb) in Hospitals-A Multi-Centre Nonlinear Time-Series Study.

Solutions are needed to inform antimicrobial stewardship (AMS) regarding balancing the access to effective antimicrobials with the need to control antimicrobial resistance. Theoretical and mathematical models suggest a non-linear relationship between antibiotic use and resistance, indicating the existence of thresholds of antibiotic use beyond which resistance would be triggered. It is anticipated that thresholds may vary across populations depending on host, environment, and organism factors. Further research is needed to evaluate thresholds in antibiotic use for a specific pathogen across different settings. The objective of this study is to identify thresholds of population antibiotic use associated with the incidence of carbapenem-resistant Acinetobacter baumannii (CRAb) across six hospital sites in Oman. The study was an ecological, multi-centre evaluation that involved collecting historical antibiotic use and CRAb incidence over the period from January 2015 to December 2019. By using non-linear time-series analysis, we identified different thresholds in the use of third-generation cephalosporins, piperacillin-tazobactam, aminoglycoside, and fluoroquinolones across participating hospitals. The identification of different thresholds emphasises the need for tailored analysis based on modelling data from each hospital. The determined thresholds can be used to set targets for each hospital AMS, providing a balance between access to these antibiotics versus controlling CRAb incidence.

Is the World Health Organization Multimodal Hand Hygiene Improvement Strategy applicable and effective at the primary care level in resource-limited settings? A quantitative assessment in healthcare centers of Faranah, Guinea.

Background: The World Health Organization Multimodal Hand Hygiene Improvement Strategy aims at reducing healthcare-associated infections; however, evidence of applicability and effectiveness at the primary care level is scarce, especially in healthcare centers in resource-limited settings. The objectives of this study were to improve hand hygiene knowledge and compliance at two healthcare centers in the region of Faranah, Guinea, to increase the availability of alcohol-based hand rub (ABHR), and to assess the effectiveness of the strategy at the primary care level. Methods: Knowledge, perceptions, and compliance were assessed prior to the intervention and compared to those of two follow-up assessments, immediately and 6 months after the intervention. The intervention consisted of training and the supply of ABHR. The monthly consumption of ABHR was monitored. Results: Baseline knowledge increased from a score of 11/25 at baseline to 16/25 at first follow-up; it then decreased to 15/25 at the second follow-up. Compliance showed an increase from 15.6% to 84.4% (P < 0.001) at the first follow-up. At the second follow-up, compliance was lower than at the first follow-up (53.2%, P < 0.001), but still more than two times higher than at baseline (P < 0.001). ABHR consumption averaged 0.77 ml per consultation. Conclusions: The World Health Organization hand hygiene strategy is an appropriate method to improve compliance and knowledge at the primary care level, but needs some adjustment: the inclusion of observation of the correctness of hand hygiene action, as well as training emphasizing the amount of ABHR to use.

Hand eczema, wet work exposure, and quality of life in health care workers in Denmark during the COVID-19 pandemic.

Background: The focus on hand hygiene during the pandemic has been reported to increase the hand eczema (HE) prevalence in health care workers (HCWs); however, detailed prospective data are missing. Objective: To evaluate changes in HE prevalence, exposures, and health-related quality of life among HCWs during the COVID-19 pandemic. Methods: In this prospective cohort study, HCWs employed at the hospitals in Copenhagen responded to a digital questionnaire at the beginning of the pandemic and 11 months thereafter. Results: A total of 795 HCWs responded to both questionnaires (83.4% women). The calculated 1-year HE prevalence decreased from 16.0% at baseline to 13.0% at follow-up. The number of hand washings decreased significantly, whereas the use of alcohol-based hand rubs on wet skin increased significantly. In a logistic regression model, increased use of alcohol-based hand rubs on wet skin was associated with HE at follow-up (odds ratio, 1.78; 95% CI, 1.11-2.87). Health-related quality of life worsened slightly at follow-up, with HE severity and frequent flareups being risk factors for a reduced health-related quality of life. Limitations: Sample size. Conclusion: In contrast to previous studies undertaken during the pandemic, we found a relatively low and stable HE prevalence. Our findings suggest that the interaction between changed exposures and HE is complex and cannot be linked to a single factor.

Hand Hygiene Compliance at Two Tertiary Hospitals in Freetown, Sierra Leone, in 2021: A Cross-Sectional Study.

Hand hygiene actions are essential to reduce healthcare-associated infections and the development of antimicrobial resistance. In this cross-sectional study at two tertiary hospitals, Freetown, Sierra Leone, we observed hand hygiene compliance (defined as using handwash with soap and water or alcohol-based hand rub (ABHR) amongst healthcare workers between June and August 2021. Using the WHO Hand Hygiene tool, observations were made in relation to the type of opportunity, different wards and types of healthcare worker. Overall, 10,461 opportunities for hand hygiene were observed, of which 5086 (49%) resulted in hand hygiene actions. ABHR was used more often than handwash (26% versus 23%, p < 0.001). Overall, compliance was significantly better: after being with a patient/doing a procedure than before (78% after body fluid exposure risk compared with 24% before touching a patient­p < 0.001); in Paediatric (61%) compared with Medical wards (46%)­p < 0.001; and amongst nurses (52%) compared with doctors (44%)­p < 0.001. Similar patterns of compliance were observed within each hospital. In summary, hand hygiene compliance was sub-optimal, especially before being with a patient or before clean/aseptic procedures. Improvement is needed through locally adapted training, hand hygiene reminders in wards and outpatient departments, uninterrupted provision of ABHR and innovative ways to change behaviour.
