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? Microorganisms 2023; 11:microorganisms11020325. [PMID: 36838290 PMCID: PMC9963388 DOI: 10.3390/microorganisms11020325] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/17/2022] [Revised: 01/18/2023] [Accepted: 01/24/2023] [Indexed: 01/31/2023] Open
Abstract
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.

Peters A, Carry J, Cave C, Sauser J, Pittet D. Acceptability of an alcohol-based handrub gel with superfatting agents among healthcare workers: a randomized crossover controlled study. Antimicrob Resist Infect Control 2022; 11:97. [PMID: 35841075 PMCID: PMC9283849 DOI: 10.1186/s13756-022-01129-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/01/2022] [Accepted: 05/31/2022] [Indexed: 11/24/2022] Open
Abstract
Introduction Healthcare workers often experience skin dryness and irritation from performing hand hygiene frequently. Low acceptability and tolerability of a formulation are barriers to hand hygiene compliance, though little research has been conducted on what specific types of formulation have higher acceptability than others. Objective To compare the acceptability and tolerability of an ethanol-based handrub gel with superfatting agents to the isopropanol-based formulations (a rub and a gel formulation) currently used by healthcare workers at the University of Geneva Hospitals, Geneva, Switzerland. Methods Forty-two participants were randomized to two sequences, testing the isopropanol-based formulation that they are using currently (Hopirub® or Hopigel®), and the ethanol-based formulation containing superfatting agents (Saniswiss Sanitizer Hands H1). Participants tested each of the formulations over 7–10 day work shifts, after which skin condition was assessed and feedback was collected. Results H1 scored significantly better than the control formulations for skin dryness (P = 0.0209), and participants felt less discomfort in their hands when using that formulation (P = 0.0448). H1 caused less skin dryness than Hopirub®/Hopigel® (P = 0.0210). Though overall preference was quite polarized, 21 participants preferred H1 intervention formulation and 17 preferred the Hopirub®/Hopigel® formulation that they normally used in their care activities. Conclusion We observed a difference in acceptability and strongly polarized preferences among the participants' reactions to the formulations tested. These results indicate that giving healthcare workers a choice between different high-quality products is important to ensure maximum acceptability.

Abstract
Skin antiseptics have important implications for public health and medicine. Although conventional antiseptics have considerable antimicrobial activity, skin toxicity and the development of resistance are common problems. Plasma-treated water has sterilization and tissue-regenerative effects. Therefore, the aim of this study was to identify whether plasma-activated water (PAW) manufactured by our microwave plasma system can be used as a novel antiseptic solution for skin protection. PAW was produced by dissolving reactive nitrogen oxide gas using microwave plasma in deionized water. The antibacterial effects of PAW against Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa, Bacillus cereus, and Salmonella typhimurium and effective concentrations were investigated by a solid agar plate assay. The factors mediating the effects of PAW were evaluated by the addition of reactive species scavengers. Cytotoxicity and cell viability assays were performed to examine the protective effect of PAW on normal skin cells. PAW exhibited excellent sterilization and no toxicity in normal skin cells. Experiments also confirmed the potential of PAW as a sanitizer for SARS-CoV-2. Our findings support the use of PAW as an effective skin disinfectant with good safety in the current situation of a global pandemic.

J Paediatr Child Health 2021; 57:1460-1466. [PMID: 33908109 DOI: 10.1111/jpc.15526] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/27/2021] [Revised: 03/10/2021] [Accepted: 04/14/2021] [Indexed: 11/29/2022]
Abstract
AIM We piloted a hand hygiene (HH) project in a ward, focusing on World Health Organization moments 1 and 4. Our aim was to design highly reliable interventions to achieve >90% compliance. METHODS Baseline HH compliance was 57 and 67% for moments 1, 4, respectively, in 2015. After the pilot ward showed sustained improvement, we launched the 'HH bundle' throughout the hospital. This included: (i) appointment of HH champions; (ii) verbal/visual bedside reminders; (iii) patient empowerment; (iv) hand moisturisers; (v) tagging near-empty handrub (HR) bottles. Other hospital-wide initiatives included: (vi) Smartphone application for auditing; (vii) 'Speak up for Patient Safety' Campaign in 2017 for staff empowerment; (viii) making HH a key performance indicator. RESULTS Overall HH compliance increased from a baseline median of 79.6-92.6% in end-2019. Moments 1 and 4 improved from 71 to 92.7% and from 77.6 to 93.2%, respectively. Combined HR and hand wash consumption increased from a baseline median of 82.6 ml/patient day (PD) to 109.2 mL/PD. Health-care-associated rotavirus infections decreased from a baseline median of 4.5 per 10 000 PDs to 1.5 per 10 000 PDs over time. CONCLUSIONS The 'HH Bundle' of appointing HH champions, active reminders and feedback, patient education and empowerment, availability of hand moisturisers, tagging near-empty hand rub bottles together with hospital-wide initiatives including financial incentives and the 'Speak Up for Patient Safety' campaign successfully improved the overall HH compliance to >90%. These interventions were highly reliable, sustained over 4 years and also reduced health-care-associated rotavirus infection rates.

Abstract
BACKGROUND In the current era, the importance of proper hand hygiene to reduce the transmission of infectious diseases has become difficult to debate. Yet, compliance rates remain low and are affected by many factors, amongst which is user acceptability of hand hygiene products. AIM The present study aimed at investigating drivers of preference towards different hand hygiene formulations. METHODS Three different formulations (liquid, foam and gel) of the same brand were randomly and blindly evaluated by 54 participants based on the WHO Protocol for Evaluation of Tolerability and Acceptability of Alcohol-based Handrubs. RESULTS The majority (76%) of respondents indicated that the product formulation impacted their level of compliance with hand hygiene protocols. The preferred formulation was liquid, with 50% of participants ranking it as first choice. General product satisfaction, the product texture, the drying speed and the ease of application, were the statistically significant drivers for participants to rank a formulation as their first choice vs not ranking it as their first choice. CONCLUSIONS When designing alcohol formulations and implementing hand hygiene protocols, understanding drivers of preference for formulations may enhance product user acceptability and therefore compliance with hand hygiene.

Abstract
Health-care-associated infections are the most prevalent adverse events of hospital care, posing a substantial threat to patient safety and burden on society. Hand hygiene with alcohol-based hand rub is the most effective preventive strategy to reduce health-care-associated infections. Over the past two decades, various interventions have been introduced and studied to improve hand hygiene compliance among health-care workers. The global implementation of the WHO multimodal hand hygiene improvement strategy and constant efforts to replace the use of soap and water with alcohol-based hand rub have led to a faster and more efficient hand cleaning method. These strategies have strongly contributed to the success of behaviour change and a subsequent decrease in health-care-associated infections and cross-transmission of multidrug-resistant organisms worldwide. The WHO multimodal behaviour change strategy requires a series of elements including system change as a prerequisite for behaviour, change, education, monitoring and performance feedback, reminders in the workplace, and an institutional safety climate. Successful adoption of the promotion strategy requires adaptation to available resources and sociocultural contexts. This Review focuses on the major advances and challenges in hand hygiene research and practices in the past 20 years and sets out various ways forward for improving this lifesaving action.

Abstract
BACKGROUND Hand hygiene is paramount in preventing healthcare-associated infections in medical environments and the spread of infectious diseases in non-medical environments. AIMS This study used a randomised controlled trial to investigate the effects of a tea tree (Melaleuca alternifolia) oil disinfectant on hand disinfection and skin condition. METHODS A tea tree oil group received 5 mL of 10% tea tree oil disinfectant mixed in a ratio of 2:2:1:15 of Melaleuca alternifolia oil, solubiliser, glycerin and sterile distilled water. Data collection took place between April 9 and April 13, 2018. The subjects were 112 healthy adults. An alcohol group received 2 mL of a gel-type hand sanitiser comprising 83% ethanol used without water; a benzalkonium chloride group received 0.8 mL of a foam-type hand sanitiser containing benzalkonium chloride used without water and a control group received no treatment. Subjective skin condition, transepidermal water loss and adenosine triphosphate were assessed, and a microbial culture test was performed following treatment. RESULTS The general characteristics and the pretreatment dependent variables did not differ significantly by group. Posttreatment adenosine triphosphate log10 values significantly differed across all four groups (F = 3.23, P = .025). Similarly, posttreatment bacterial density log10 values differed significantly across the tea tree oil, alcohol, benzalkonium chloride and control groups (F = 91.71, P < .001). CONCLUSION The study confirmed that tea tree oil disinfectant is effective for hand disinfection. Accordingly, tea tree oil disinfectants may be introduced to nursing practice as a new hand hygiene product to prevent and reduce healthcare-associated infections.

Abstract
BACKGROUND Occupational skin disease (OSD) is a common health issue in the food processing sector. However, risk factors for OSD are suspected to differ according to the nature of the operation. OBJECTIVE To ascertain if the risk factors for OSD vary depending on the type of food processing operation, namely meat processing vs. a commercial bakery. METHODS Participants were asked to answer questions regarding workplace exposures and the current skin condition of their hands. Bivariate analyses were conducted to identify differences between the two participating operations. RESULTS The meat processing workers were more likely to have wet work exposure, used hand sanitizer more often and changed their gloves more frequently. These findings from meat processing represented a statistically significant difference compared to the commercial bakery workers. Also, workers from meat processing reported more severe skin symptoms. CONCLUSIONS Risk factors for OSD apparently differ between types of food processing operations. Differences in the nature of skin symptoms were also found between the two participating operations. It is therefore suggested that future studies examining OSD within the food processing sector should evaluate this health effect based on the nature of operations rather than the sector as a whole.

Abstract
The global use of alcohol-based hand sanitizers (ABHS) as an important means of controlling the transmission of infectious disease has increased significantly as governments and public health agencies across the world advocated hand hygiene as a preventative measure during the COVID-19 pandemic. Although the performance of these products is most commonly defined as a function of their alcohol concentration, they are multifaceted products in which an interplay of several factors is important in determining efficacy. This paper discusses the interplay between ABHS input (formulation) factors and output (product performance) factors in the context of a multidimensional perspective using a novel representative paradigm. In the model, represented in the form of a three-dimensional tetrahedron, each of the faces represents inputs in the manufacturing of the ABHS product, which are the type and amount of alcohol, the inactive ingredients, the formulation and the manufacturing practices. The four corners of the tetrahedron represent the product performance factors which include product efficacy, sensory characteristics, usage and compliance and product safety. The multidimensional approach to the formulation and evaluation of ABHS shows that several factors contribute to the effectiveness and utility of these products. The paradigm provides a useful framework for manufacturers of ABHS and related healthcare products.

Abstract
Purpose Rubbing the hands with alcohol-based handrub (ABHR) is globally recommended as the preferred approach to prevent healthcare-associated infections in most routine encounters with patients, except in cases handwashing with soap and water is advised. Inappropriate utilization of ABHR could have detrimental effects, most importantly during the coronavirus disease (COVID-19) pandemic, which include exposure of healthcare professionals to healthcare-associated infections and the development of resistant microorganisms. In a hospital setting, the utilization of ABHR among frontline healthcare workers including pharmacy professionals is low. Therefore, the purpose of this study was to explore the current practice of hand rubbing among pharmacy professionals in public hospitals of Addis Ababa during the pandemic of COVID-19. Methods The study was a cross-sectional study using a self-reported questionnaire conducted among pharmacy professionals in public hospitals found in Addis Ababa from 10th May to 9th June, 2020 to recognize ABHR utilization rate. Data were collected on a sample of 384 pharmacy professional by a self-administered questionnaire. Data analysis was done using software for the statistical package for social science version 25.0. To identify the significant predictors of ABHR utilization practice bivariable and multivariable logistic regressions were carried out. Crude odds ratio and adjusted odds ratio with 95% confidence interval were calculated to determine the predictors. Results Out of 384 participants, three hundred and four participants were included in the final analyses after the exclusion of incomplete responses. Female participants represented 41.4% of the study participants. More than half (58.9%) of the pharmacy professionals had sufficient knowledge on ABHR utilization for COVID-19 prevention. Similarly, 56.6% of pharmacy professionals had positive attitude towards ABHR for COVID-19 prevention. But only 35.9% of the study participants had good ABHR utilization practice. Conclusion Despite the modest level of knowledge and attitude towards ABHR, pharmacy professionals’ utilization practice of ABHR for COVID-19 prevention was found to be suboptimal. Provision of ABHR solutions through hospitals and increasing the awareness of pharmacy professionals on ABHR needs to be encouraged.

Abstract
The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has spread globally. Although measures to control SARS-CoV-2, namely, vaccination, medication, and chemical disinfectants are being investigated, there is an increase in the demand for auxiliary antiviral approaches using natural compounds. Here we have focused on hydroxytyrosol (HT)-rich aqueous olive pulp extract (HIDROX®) and evaluated its SARS-CoV-2-inactivating activity in vitro. We showed that the HIDROX solution exhibits time- and concentration-dependent SARS-CoV-2-inactivating activities, and that HIDROX has more potent virucidal activity than pure HT. The evaluation of the mechanism of action suggested that both HIDROX and HT induced structural changes in SARS-CoV-2, which changed the molecular weight of the spike proteins. Even though the spike protein is highly glycosylated, this change was induced regardless of the glycosylation status. In addition, HIDROX or HT treatment disrupted the viral genome. Moreover, the HIDROX-containing cream applied on film showed time- and concentration-dependent SARS-CoV-2-inactivating activities. Thus, the HIDROX-containing cream can be applied topically as an antiviral hand cream. Our findings suggest that HIDROX contributes to improving SARS-CoV-2 control measures.

Abstract
BACKGROUND In the current situation of the COVID-19 pandemic, healthcare workers (HCWs) have to comply with hygiene conditions and use gloves more frequently and for a longer period of time than they would previously to avoid infection and prevent transmission. AIMS We aimed to characterize the adverse skin reactions occurring after hand hygiene and glove use in HCWs in a tertiary university hospital to determine the possible causative factors and whether the use of these measures is affected. METHODS Between April 15 and May 1, 2020, a cross-sectional survey was conducted, using online questionnaire, answered by HCWs in a tertiary university hospital. RESULTS The increase in general hand-skin problems during the pandemic period was statistically significant (P = .004). The most common symptom was dryness. During the pandemic period, 67 (24.3%) HCWs thought that the conditions were caused by glove use, and 197 (71.4%) thought that they were due to alcohol-based hand antiseptics. The incidence of other hand-skin conditions except for vesicles was statistically higher in women than in men (P < .001). CONCLUSIONS Increased number of hand-skin conditions during the pandemic should not be ignored, since hand hygiene and glove use are expected to increase.

Abstract
The effect of alcohol hand rub was tested in eradicating Escherichia coli, and compared with hand wash using ozonized tap water or soap and water. Alcohol eradicated all bacteria in 10 out of 35 participants, but with an average (SD) of 2330 (4227) cfu/mL left after disinfection, whereas ozonized water removed all bacteria in 10 out of 55 participants, with an average of only 538 (801) cfu/mL left (P = 0.045). Soap washing was the most effective with total removal of bacteria in six out of 20 participants, with an average of 98 (139) cfu/mL (P = 0.048 and 0.018 versus ozonized water and alcohol, respectively).

Abstract
Background: The burden of healthcare-associated infections (HAIs) is greatest in low- and middle-income countries (LMICs); surgical site infections (SSIs) are the most common HAI in LMICs. Hand hygiene is the single most effective strategy for reducing HAIs and the transmission of antimicrobial drug-resistant pathogens. Similarly, effective surgical hand preparation is a critical step in the prevention of SSIs in the surgical patient. Methods: Surgical hand preparation (SHP) is a seemingly simple activity that is easily overlooked. Performed properly, however, along with other measures, it has the potential to reduce SSIs in LMICs. The article reviews the current state of surgical hand preparation in LMICs. Results: Alcohol-based handrubs (ABHRs) have received wide acceptance by healthcare workers for both hand hygiene and SHP; when mixed with emollients, ABHRs retain efficacy against microorganisms and gain skin tolerability and user acceptability. Healthcare institutions in many LMICs face difficulties obtaining the products needed to ensure effective SHP using ABHRs. Conclusion: The ABHRs are the most efficacious surgical hand preparation products available today. They are cost-effective and can safely be prepared locally in hospitals, even in LMICs. The challenge of access to ABHRs should be addressed by national and local governments, through advocacy by healthcare workers coupled with continued lobbying and campaigns by the World Health Organization. Effective surgical hand preparation, like hand hygiene, saves lives.

Abstract
Background The World Health Organization (WHO) ethanol-based handrub (EBHR) formulation contains 1.45% glycerol as an emollient to protect healthcare workers' (HCWs) skin against dryness and dermatitis. However, glycerol seems to negatively affect the antimicrobial efficacy of alcohols. In addition, the minimal concentration of glycerol required to protect hands remain unknown. We aim to evaluate the tolerance of HCWs to the WHO EBHR formulation using different concentrations of glycerol in a tropical climate healthcare setting. Methods We conducted a cluster-randomized, double-blind, crossover study among 40 HCWs from an intensive care unit of a tertiary-care hospital in Brazil, from June 1st to September 30, 2017. We tested the WHO EBHR original formulation containing 1.45% glycerol against three other concentrations (0, 0.5, and 0.75%). HCWs used one formulation at a time for seven working days during their routine practice and then had their hands evaluated by an external observer using the WHO scale for visual inspection. Participants also used a WHO self-evaluation tool to rate their own skin condition. We used a generalized estimating equations of the logit type to compare differences between the tolerability to different formulations. Results According to the independent observation, participants had 2.4 times (95%CI: 1.12-5.15) more chance of having a skin condition considered good when they used the 0.5% compared to the 1.45% glycerol formulation. For the self-evaluation scale, participants were likely to have a worst evaluation (OR: 0.23, 95%CI: 0.11-0.49) when they used the preparation without glycerol compared to the WHO standard formulation (1.45%), and there were no differences between the other formulations used. Conclusion In a tropical climate setting, the WHO-modified EBHR formulation containing 0.5% glycerol led to better ratings of skin tolerance than the original formulation, and, therefore, may offer the best balance between skin tolerance and antimicrobial efficacy.

Abstract
Background: Hand hygiene is considered as the most important strategy for preventing healthcare infections. Objective: In this single-arm study, skin tolerance, effectiveness and prolonged efficacy, and adherence to use an alcohol-based hand rub (ABHR) solution among hospital nurses was evaluated. Methods: Nurses were recruited in the main hospital of Molise Region, Central Italy. Skin reactions during 12-week follow-up were self-reported by nurses and, when occurring examined by hospital dermatologist. Samples were collected from palms and fingertips before and after ABHR, also at random times during work. Results: Dermatological reactions were not reported by 20 nurses (15 female and 5 male, aged 30–59 years) after product use. Microbial counts decreased by 99% (2Log10) in 75%, with higher reduction in palm than fingertips (99% vs 70% respectively). Analysis of six randomly collected samples after 10–20 and 30–40 min from the last use showed a satisfactory prolonged efficacy. Discussion: Beyond high effectiveness to reduce transient microbiota, no skin reactions were observed, likely due to the camomile, thyme and eucalyptus extracts contained within the gel. This study, addressing technical questions of a commercialised product, provides useful information for public health authorities faced with a choice of hand disinfectants, evaluating cost-effectiveness and cost-benefit in the light of the huge amount of these products needed at hospital level.

Abstract
BACKGROUND Effective alcohol-based hand rubs (ABHRs) and healthcare worker compliance with hand hygiene guidelines are important in the prevention of infection transmission in healthcare settings. Compliance to hand hygiene guidelines is affected by many factors including education, ABHR availability, time pressure, skin health, and user acceptance of the sensory properties of ABHRs during and after application. AIM To examine the effect of ABHR format (gel/foam/liquid) and dose (0.7 mL, 1.5 mL, 3 mL) on its sensory properties and acceptability, and to consider how this might affect healthcare workers' hand hygiene compliance. METHODS Sensory descriptive analysis established key sensory differences between ten market-leading ABHRs (three gels, four foams, two liquids, one aerosol foam). Focus groups reinforced these differences. FINDINGS All formats were less desirable at the highest dose as they were more difficult to handle than the lower doses. Foams and gels became stickier, less clean-feeling and slower to dry at higher doses. Liquids gave a cleaner, smoother, more moisturized feel, but the increased difficulty in handling and applying the product negated these benefits. Overall, the gel and foam formats were more desirable than the liquid. The key desirable properties include: fast absorption, soft/moisturized hand feel, not sticky, clean feel, and low smell. CONCLUSION The 1.5 mL dose yielded the most acceptable properties with no extreme negative consequences. The foam provided the benefits of both the liquid and gel and combined them into a more widely acceptable format that may lead to greater hand hygiene compliance.

Abstract
Background To prevent cross infection the surgical team perform preoperative hand disinfection before dressed in surgical gowns and gloves. Preoperative hand disinfection does not make hands sterile and the surgical glove cuff end has been regarded as a weak link, since it is not a liquid-proof interface. The aims were to investigate if there were differences in bacterial growth and recolonization of hands between operating room nurses and non-health care workers as well as to investigate if bacterial growth existed at the surgical glove cuff end during surgery. Methods This pilot project was conducted as an exploratory comparative clinical trial. Bacterial cultures were taken from the glove and gown interface and at three sites of the hands of 12 operating room nurses and 13 non-health care workers controls directly after preoperative hand disinfection and again after wearing surgical gloves and gowns. Colony forming units were analysed with Mann-Whitney U test and Wilcoxon Sign Ranks test comparing repeated measurements. Categorical variables were evaluated with chi-square test or Fisher’s exact test. Results Operating room nurses compared to non-health care workers had significant higher bacterial growth at two of three culture sites after surgical hand disinfection. Both groups had higher recolonization at one of the three culture sites after wearing surgical gloves. There were no differences between the groups in total colony forming units, that is, all sampling sites. Five out of 12 of the operating room nurses had bacterial growth at the glove cuff end and of those, four had the same bacteria at the glove cuff end as found in the cultures from the hands. Bacteria isolated from the glove cuff were P. acnes, S. warneri, S. epidermidis and Micrococcus species, the CFU/mL ranged from 10 to 40. Conclusions There were differences in bacterial growth and re-colonization between the groups but this was inconclusive. However, bacterial growth exists at the glove cuff and gown interface, further investigation in larger study is needed, to build on these promising, but preliminary, findings. Trial registration Trial registration was performed prospectively at Research web (FOU in Sweden, 117,971) 14/01/2013, and retrospectively at ClinicalTrials.gov (NCT02359708). 01/27/2015.

Abstract
Ethanol is used worldwide in healthcare facilities for hand rubbing. It has been reported to have a stronger and broader virucidal activity compared with propanols. The aim of this review was to describe the spectrum of virucidal activity of ethanol in solution or as commercially available products. A systematic search was conducted. Studies were selected when they contained original data on reduction of viral infectivity from suspension tests (49 studies) and contaminated hands (17 studies). Ethanol at 80% was highly effective against all 21 tested, enveloped viruses within 30 s. Murine norovirus and adenovirus type 5 are usually inactivated by ethanol between 70% and 90% in 30 s whereas poliovirus type 1 was often found to be too resistant except for ethanol at 95% (all test viruses of EN 14476). Ethanol at 80% is unlikely to be sufficiently effective against poliovirus, calicivirus (FCV), polyomavirus, hepatitis A virus (HAV) and foot-and-mouth disease virus (FMDV). The spectrum of virucidal activity of ethanol at 95%, however, covers the majority of clinically relevant viruses. Additional acids can substantially improve the virucidal activity of ethanol at lower concentrations against, e.g. poliovirus, FCV, polyomavirus and FMDV although selected viruses such as HAV may still be too resistant. The selection of a suitable virucidal hand rub should be based on the viruses most prevalent in a unit and on the user acceptability of the product under frequent-use conditions.

Abstract
OBJECTIVES Hygiene education appears to be the commonest school-based intervention for preventing infectious diseases, especially in the developing world. Nevertheless, there remains a gap in literature regarding a school-specific theory-based framework for designing a hand hygiene educational intervention in schools. We sought to suggest a framework underpinned by psychosocial theories towards bridging this knowledge gap. Furthermore, we sought to propound a more comprehensive definition of hand hygiene which could guide the conceptualisation of hand hygiene interventions in varied settings. METHODS Literature search was guided by a standardized tool and literature was retrieved on the basis of a predetermined inclusion criteria. Databases consulted include PubMed, ERIC, and EBSCO host (Medline, CINAHL, PsycINFO, etc.). Evidence bordering on a theoretical framework to aid the design of school-based hand hygiene educational interventions is summarized narratively. RESULTS School-based hand hygiene educational interventions seeking to positively influence behavioural outcomes could consider enhancing psychosocial variables including behavioural capacity, attitudes and subjective norms (normative beliefs and motivation to comply). CONCLUSIONS A framework underpinned by formalized psychosocial theories has relevance and could enhance the design of hand hygiene educational interventions, especially in schools.

Abstract
Two of the most important skin care categories with profound dermatologic implications are cleansers and moisturizers. Cleansers are composed of alkaline soaps or the less barrier-damaging synthetic detergents, known as syndets. The lower skin irritation and dryness found with syndets are related to their reduced tendency to cause protein denaturation due to the charge density of protein-bound micelle-like surfactant aggregates. Many cleansing formulations are available for purchase to meet hygiene needs varying by sex, age, ethnicity, occupation, environment, personal preferences, and the presence or absence of skin disease. This discussion covers the science of skin cleansing.

Abstract
Background Hand hygiene (HH) is an essential component for preventing and controlling of healthcare-associated infection (HAI), whereas compliance with HH among health care workers (HCWs) is frequently poor. This study aimed to assess compliance and correctness with HH before and after the implementation of a multimodal HH improvement strategy launched by the World Health Organization (WHO). Methods A quasi-experimental study design including questionnaire survey generalizing possible factors affecting HH behaviors of HCWs and direct observation method was used to evaluate the effectiveness of WHO multimodal HH strategy in a hospital of Traditional Chinese Medicine. Multimodal HH improvement strategy was drawn up according to the results of questionnaire survey. Compliance and correctness with HH among HCWs were compared before and after intervention. Also HH practices for different indications based on WHO “My Five Moments for Hand Hygiene” were recorded. Results In total, 553 HCWs participated in the questionnaire survey and multimodal HH improvement strategy was developed based on individual, environment and management levels. A total of 5044 observations in 23 wards were recorded in this investigation. The rate of compliance and correctness with HH improved from 66.27% and 47.75% at baseline to 80.53% and 88.35% after intervention. Doctors seemed to have better compliance with HH after intervention (84.04%) than nurses and other HCWs (81.07% and 69.42%, respectively). When stratified by indication, compliance with HH improved for all indications after intervention (P < 0.05) except for “after body fluid exposure risk” and “after touching patient surroundings”. Conclusion Implementing the WHO multimodal HH strategy can significantly improve HH compliance and correctness among HCWs.

Abstract
BACKGROUND Proper hand hygiene with soap and detergents prevents the transmission of many infectious diseases. However, commercial detergents are less likely to be accessible or affordable to poor people in remote rural areas. These people traditionally use some plant parts as a detergent even though their antibacterial activity has not been yet investigated. Therefore, this study aims to determine the antibacterial activities of some of the plants against bacteria isolated from humans. METHODS Plants selected for this study are Phytolacca dodecandra fruits, Rumex nepalensis leaves, Grewia ferruginea bark and leaves. The samples of these plants were collected from rural areas of Jimma town based on their ethno-botanical survey and information on their local use. Acetone was used as a solvent to extract the bioactive constituents of the plants. The antibacterial activities of the plants were evaluated against reference strains and bacteria isolated from humans using disc diffusion and macro dilution methods. RESULTS The plant extracts have shown varying antimicrobial activities against the bacterial species tested. Susceptibility testing shows zones of inhibition ranging from 8.0 ± 1.0 mm to 20.7 ± 5.5 mm. The MIC and MBC of the plants against the bacterial species tested were 3.13 and 12.5 mg/ml respectively. These variations are attributed to different concentrations of the bioactive constituents of the extracts like saponins, tannins, flavonoids and terpenoids. CONCLUSION The studied plants can contribute to achieve better personal hygiene since they are effective against different bacterial agents and are freely available in rural areas.

Comparative assessment of local tolerance of alcohols commonly used in alcohol-based hand rubs for hand hygiene. Toxicol In Vitro 2017; 44:142-153.

Abstract
Hand hygiene plays a key role in nosocomial infection prevention. To achieve users' adherence, products' dermal tolerance is essential. We aimed at making a comparative assessment of skin irritation and phototoxicity of the 3 alcohols commonly used in alcohol-based hand rubs (Ethanol, Propan-2-ol, Propan-1-ol) at 60, 70, 80 or 85% w/w in water or with co-formulates (hydrating, emollient and skin protective agents). In vitro validated OECD methods 439 and 432 were used. For irritation, EpiSkin™ Small Model was the chosen Reconstructed Human Epidermis (RhE). For phototoxicity, co-formulates alone or in mixture with and without alcohol were tested using BALB/c 3T3 cell cultures. Whilst Ethanol and Propan-2-ol could not be differentiated and displayed good skin tolerance profiles, Propan-1-ol based products lead to significant viability impairments of RhE at 60, 70 or 80% and at 60% in the presence of co-formulates. However, these results could not be reproduced in another RhE model. Taking also into account bibliographic data on Propan-1-ol, this suggests that our results are probably related to a lack of specificity of the used RhE. Therefore, it can be relevant in case of significant results to use two different RhE models before performing any classification and/or performing any complementary tests.

Abstract
Hand Hygiene is the cheapest and simplest way to prevent the spread of infection, however international compliance is below than 40% (WHO, 2009). In the experience of Al Wakra Hospital, the improvement in hand hygiene compliance highlighted not just interventions towards training and education but also behavioral motivation and physical allocations of hand hygiene appliances and equipment. Through motivating the behavioral, emotional, physical and intellectual dimensions of the different healthcare worker professions, hand hygiene compliance has increased from 60.78% in 2011 to 94.14% by the end of December 2015. It took 25 months of continuous and collaborative work with different healthcare workers to reach the 90% hand hygiene target. "Together, we have reached our goals and together we fight against infections! Because we always strive for excellence in everything we do - that is our vision here in Al Wakra Hospital."

Abstract
BACKGROUND The aim of this prospective multicenter study was to explore the usefulness of a modified World Health Organization (WHO) hand hygiene program to increase compliance with hand hygiene among health care workers (HCWs) in Latvia, Lithuania, Saint Petersburg (Russia), and Sweden and to provide a basis for continuing promotion of hand hygiene in these countries. The study was carried out in 2012. Thirteen hospitals participated, including 38 wards. METHODS Outcome data were handrub consumption, compliance with hand hygiene measured with a modified WHO method, and assessment of knowledge among HCWs. Interventions were education of the nursing staff, posters and reminders in strategic places in the wards, and feedback of the results to nursing staff in ward meetings. RESULTS Feedback of results was an effective tool for education at the ward level. The most useful outcome measurement was handrub consumption, which increased by at least 50% in 30% of the wards. In spite of this, handrub consumption remained at a low level in many of the wards. CONCLUSIONS There are several reasons for this, and the most important were self-reported nursing staff shortage and fear of adverse effects from using alcoholic handrub and verified skin irritation.

Abstract
BACKGROUND Hand hygiene at the point of care is recognized as a best practice for promoting compliance at the moments when hand hygiene is most critical. The objective of this study was to compare knowledge, attitudes, and practices of US and Canadian frontline health care personnel regarding hand hygiene at the point of care. METHODS Physicians and nurses in US and Canadian hospitals were invited to complete a 32-question online survey based on evidence supporting point of care hand hygiene. Eligible health care personnel were in direct clinical practice at least 50% of the time. RESULTS Three hundred fifty frontline caregivers completed the survey. Among respondents, 57.1% were from the United States and 42.9% were from Canada. Respondents were evenly distributed between physician and nurses. The US and Canadian respondents gave identical ranking to their perceived barriers to hand hygiene compliance. More than half of the respondents from both the United States and Canada agreed or strongly agreed that they would be more likely to clean their hands when recommended if alcohol-based handrub was closer to the patient. CONCLUSION This survey demonstrates that similarities between Canada and the United States were more common than not, and the survey raises, or suggests, potential knowledge gaps that require further illumination.

Abstract
Proper hand hygiene is critical for preventing healthcare-associated infection, but provider compliance remains suboptimal. While signs are commonly used to remind physicians and nurses to perform hand hygiene, the content of these signs is rarely based on specific, validated health behavior theories. This observational study assessed the efficacy of a hand hygiene sign disseminated by the Centers for Disease Control and Prevention in an intensive care unit compared to an optimized evidence-based sign designed by a team of patient safety experts. The optimized sign was developed by four patient safety experts to include known evidence-based components and was subsequently validated by surveying ten physicians and ten nurses using a 10 point Likert scale. Eighty-two physicians and 98 nurses (102 females; 78 males) were observed for hand hygiene (HH) compliance, and the total HH compliance rate was 16%. HH compliance was not significantly different among the signs (Baseline 10% vs. CDC 18% vs. OIS 20%; p=0.280). The findings of this study suggest that even when the content and design of a hand hygiene reminder sign incorporates evidence-based constructs, healthcare providers comply only a fraction of the time.

Abstract
Environmental surfaces have been clearly linked to transmission of key pathogens in health care facilities, including methicillin-resistant Staphylococcus aureus, vancomycin-resistant Enterococcus, Clostridium difficile, norovirus, and multidrug-resistant gram-negative bacilli. For this reason, routine disinfection of environmental surfaces in patient rooms is recommended. In addition, decontamination of shared medical devices between use by different patients is also recommended. Environmental surfaces and noncritical shared medical devices are decontaminated by low-level disinfectants, most commonly phenolics, quaternary ammonium compounds, improved hydrogen peroxides, and hypochlorites. Concern has been raised that the use of germicides by health care personnel may increase the risk of these persons for developing respiratory illnesses (principally asthma) and contact dermatitis. Our data demonstrate that dermatitis and respiratory symptoms (eg, asthma) as a result of chemical exposures, including low-level disinfectants, are exceedingly rare. Unprotected exposures to high-level disinfectants may cause dermatitis and respiratory symptoms. Engineering controls (eg, closed containers, adequate ventilation) and the use of personal protective equipment (eg, gloves) should be used to minimize exposure to high-level disinfectants. The scientific evidence does not support that the use of low-level disinfectants by health care personnel is an important risk for the development of asthma or contact dermatitis.

Am J Clin Nutr 2016; 103:1357-69.

Abstract
BACKGROUND The causes of stunting are complex but likely include prenatal effects, inadequate postnatal nutrient intake, and recurrent infections. Low-birth-weight (LBW) infants are at high risk of stunting. More than 25% of live births in low- and middle-income countries are at full term with low birth weight (FT-LBW). Evidence on the efficacy of specific interventions to enhance growth in this vulnerable group remains scant. OBJECTIVE We investigated the independent and combined effects of a directed use of a water-based hand sanitizer (HS) and a mineral- and vitamin-enhanced micronutrient powder (MNP) (22 minerals and vitamins) to prevent infections and improve nutrient intake to reduce stunting in FT-LBW infants. DESIGN The study was a prospective 2 × 2 factorial, cluster-randomized trial in 467 FT-LBW infants during 2 periods: from 0 to 5 mo postpartum (0-180 d postpartum) and from 6 to 12 mo postpartum (181-360 d postpartum) with the use of 48 clusters. All groups received the same general nutrition, health, and hygiene education (NHHE) at enrollment and throughout the 12 mo. Group assignments initially included the following 2 groups: no HS (control) group or HS from 0 to 5 mo postpartum. These assignments were followed by further divisions into the following 4 groups from 6 to 12 mo postpartum: 1) no HS and no MNP (control), 2) HS only, 3) MNP only, and 4) HS and MNP. RESULTS When delivered in combination with NHHE, the use of an HS showed no additional benefit in reducing indicators of infection in the first or second half of infancy or the likelihood of stunting at 12 mo postpartum. FT-LBW infants who received the MNP (with or without the HS) were significantly less likely to be stunted at 12 mo than were controls (OR: 0.35; 95% CI: 0.15, 0.84; P = 0.017). CONCLUSIONS The use of a mineral- and vitamin-enhanced MNP significantly reduced stunting in FT-LBW infants in this high-risk setting. The use of a water-based HS did not have an additive effect. This trial was registered at clinicaltrials.gov as NCT01455636.

Abstract
BACKGROUND Optimizing user satisfaction with alcohol-based hand rubs (ABHR) may be vital to enhance hand hygiene performance. This study tested the tolerability and acceptability of a new ABHR (EVO9; Ecolab) in healthcare workers under daily working conditions and evaluated the practicability of the corresponding WHO protocol. METHODS We strictly applied the WHO single product ABHR evaluation protocol. A trained observer assessed hand skin conditions of healthy volunteers using at least 30 ml ABHR per day during their clinical work at baseline, day 3-5 and one month (visit 1-3). Participants rated ABHR tolerability and acceptability at visit 2 and 3. Additionally, we registered study time for participants and study team. RESULTS Among 46 volunteers, 76% were female; 37% nurses, 28% physicians. Skin was observer-rated "not" or "incidentally" dry in 64.4%, 77.8%, and 90.9% participants at visit 1, 2, and 3, respectively. EVO9 was scored ≥5 (progressive scale, 1-7) for appearance, intactness, moisture content, and sensation by 95.7%, 97.7%, 88.9%, and 97.8% participants at visit 3, respectively. All WHO benchmarks were exceeded except for "speed of drying" at visit 2, and "texture" at visit 2 and 3. Cumulative study time expenditure was 14 days for the observer and four days for participants. CONCLUSIONS EVO9 was well tolerated and accepted according to the WHO single ABHR evaluation protocol with the potential for improvement for stickiness. The WHO protocol is feasible but requires considerable time and logistics. It does not preclude bias, in this case especially due to the necessary switch to personal dispensers.

Abstract
OBJECTIVE this study aimed to evaluate the efficacy of hand hygiene performed with two different soap formulations: 0.3% Melaleuca alternifolia essential oil versus 0.5% triclosan, and to compare them with two reference hygiene procedures: the official methodology procedure (soft soap) versus the draft version of the procedure (soft soap + propan-2-ol). METHOD using the European EN 1499 method, logarithmic reduction factors were determined for the number of colony forming units of Escherichia coli K12 before and after hand hygiene of 15 volunteer subjects, and compared using the one-tailed Wilcoxon test. RESULTS referring to the soft soap, there was no difference between the performance of soap with 0.3% M. alternifolia and soap containing 0.5% triclosan. The soft soap + propan-2-ol proved to be more effective than the other hand hygiene procedures. CONCLUSION studies to verify the therapeutic efficacy of essential oil in hand hygiene can improve adherence to this practice.

Abstract
BACKGROUND According to the World Health Organization guidelines, field tests, in the context of a bid for the supply of alcohol-based hand rubs, should take into account climatic region, test period, products already in use, and type of use (hygienic or surgical) when assessing tolerance. This laborious method is often contested. OBJECTIVE To conduct a post hoc analysis of the data of a large bid, including 5 factors, to validate the relevance of their inclusion. METHODS For the purposes of the bid, products were compared in terms of the 4 World Health Organization tolerance criteria (appearance, intactness, moisture content, sensation) during product testing and were separated into groups on the basis of the studied factors. The post hoc analysis method included (1) comparison of the mean before-and-after difference based on the self-evaluation of the skin with the 4 World Health Organization tolerance criteria, between climatic regions, periods, products in use, test product, and the type of use; (2) generalized linear models, taking into account all studied factors. RESULTS The analysis included data for 1,925 pairs of professionals. The means of the differences observed were independently and significantly associated with the test period (P<.001), the hygienic or surgical use (P=.010 to .041, not significant for appearance), the product already in use (significant for appearance P=.021), and the test product (P<.001). The association with climatic region was found to be significant only in the nonadjusted analysis. CONCLUSION The type of use, the test period, and the product in use should be taken into account when designing field tests of alcohol-based hand rubs.

Abstract
AIM To investigate the barriers to and motivators for learning infection prevention and control as identified by midwifery students. METHODS Semi-structured interviews were undertaken with 15 undergraduate midwifery students within one large university. Data were analysed using Framework Analysis. RESULTS Barriers to good clinical practice were identified by students which were concordant with previous literature related to reasons for non-compliance with infection control precautions. Issues such as competing demands specific to midwifery were also identified. Factors which act as barriers to learning good practice in placements included conflicting information and practices from different staff and placement areas and staff attitudes towards students who tried to comply with precautions. Motivators to good practice included the perceived vulnerability of infants to infection, the role modelling of good practice to new mothers and the monitoring of practice. CONCLUSIONS This study demonstrated that midwifery students perceive barriers and motivators to learning infection prevention and control in their clinical placements. Many of the barriers identified are related to the attitudes and practices of qualified staff. Some of the motivators are related specifically to midwifery practice. Midwives need to be aware of the effects of what is observed in practice on midwifery students and how their practices and attitudes can influence learning both positively and negatively. As healthcare-associated infection and poor compliance with precautions are a global problem, this research should be of benefit to midwives and midwifery educators worldwide in terms of addressing barriers and ensuring better clinical education.

Hand hygiene compliance in the critical care setting: a comparative study of 2 different alcohol handrub formulations. Am J Infect Control 2013; 41:136-9.

Abstract
BACKGROUND Hand hygiene (HH) compliance can be affected by the accessibility of products (alcohol-based products or chlorhexidine) and by the formulations of these products. There are few published studies comparing different alcohol-based hand disinfection formulations. METHODS This study was conducted in a 41-bed medical-surgical intensive care unit at a private tertiary care hospital. Over a 16-week period, we assessed HH compliance by direct observation of practice using iPods and measurement of the amount of product used [alcohol and chlorhexidine] in two 4-room pods in which an alcohol gel product was used compared with two other 4-room pods in which an alcohol-based foam formulation was used. RESULTS A total of 3,895 opportunities for HH were observed, and the overall rate of HH compliance was 36.9%. No statistically significant differences were found in overall HH compliance or alcohol-based HH compliance between the alcohol foam unit and the alcohol gel unit. However, there was a statistically significant difference in chlorhexidine HH compliance between the alcohol foam unit and the alcohol gel unit (7.0% [130 of 1,853] vs 3.8% [77 of 2,042]; P < .01). CONCLUSIONS Alcohol handrub use was greater than chlorhexidine use, but HH compliance was low in both units independent of the alcohol formulation available. The similarity of use of both alcohol formulations suggests that health care workers tend to use whatever product is readily available.

J Epidemiol Glob Health 2012; 2:193-8. [PMID: 23856500 PMCID: PMC7320321 DOI: 10.1016/j.jegh.2012.10.001] [Citation(s) in RCA: 8] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/10/2012] [Revised: 10/09/2012] [Accepted: 10/10/2012] [Indexed: 11/18/2022] Open
Abstract
Background: The 3 ml volume currently used as the hand hygiene (HH) measure has been explored as the pertinent dose for an indirect indicator of HH compliance. A multicenter study was conducted in order to ascertain the required dose using different products. Method: The average contact duration before drying was measured and compared with references. Effective hand coverage had to include the whole hand and the wrist. Two durations were chosen as points of reference: 30 s, as given by guidelines, and the duration validated by the European standard EN 1500. Each product was to be tested, using standardized procedures, by three nosocomial infection prevention teams, for three different doses (3, 2 and 1.5 ml). Results: Data from 27 products and 1706 tests were analyzed. Depending on the product, the dose needed to ensure a 30-s contact duration in 75% of tests ranging from 2 ml to more than 3 ml, and to ensure a contact duration exceeding the EN 1500 times in 75% of tests ranging from 1.5 ml to more than 3 ml. The aftermath interpretation is the following: if different products are used, the volume utilized does not give an unbiased estimation of the HH compliance. Other compliance evaluation methods remain necessary for efficient benchmarking.

Abstract
BACKGROUND The hands of health care workers continue to be the main vector for nosocomial infection in hospitals. The purpose of the current research was to capture the health beliefs and self-reported behaviors of US health care workers to better understand why workers avoid hand hygiene and what prompts them to wash. METHODS An online survey of health care workers assessed their reasons for washing their hands, reasons for not washing, and what cues prompted the decision to wash or not wash in a variety of locations. RESULTS The findings were that hand hygiene could be cued by an external situation but tended to be motivated internally. Hand hygiene was avoided because of situational barriers. CONCLUSION The reasons for performing hand hygiene can be situated in the internally motivated Theory of Planned Behavior; however, the reasons for not performing hand hygiene tend to be situational and affected by the environment. The results may be used to design programs, products, and systems that promote appropriate hand hygiene practices. Principles for design of these programs and products are provided.
