Summary

Background

The National Hand Hygiene Initiative (NHHI) is a standardised culture-change programme based on the WHO My 5 Moments for Hand Hygiene approach to improve hand hygiene compliance among Australian health-care workers and reduce the risk of health-care-associated infections. We analysed its effectiveness.

Methods

In this longitudinal study, we assessed outcomes of the NHHI for the 8 years after implementation (between Jan 1, 2009, and June 30, 2017), including hospital participation, hand hygiene compliance (measured as the proportion of observed Moments) three times per year, educational engagement, cost, and association with the incidence of health-care-associated Staphylococcus aureus bacteraemia (HA-SAB).

Findings

Between 2009 and 2017, increases were observed in national health-care facility participation (105 hospitals [103 public and two private] in 2009 vs 937 hospitals [598 public and 339 private] in 2017) and overall hand hygiene compliance (36 213 [63·6%] of 56 978 Moments [95% CI 63·2–63·9] in 2009 vs 494 673 [84·3%] of 586 559 Moments [84·2–84·4] in 2017; p<0·0001). Compliance also increased for each Moment type and for each health-care worker occupational group, including for medical staff (4377 [50·5%] of 8669 Moments [95% CI 49·4–51·5] in 2009 vs 53 620 [71·7%] of 74 788 Moments [71·4–72·0]; p<0·0001). 1 989 713 NHHI online learning credential programmes were completed. The 2016 NHHI budget was equivalent to AUD$0·06 per inpatient admission nationally. Among Australia’s major public hospitals (n=132), improved hand hygiene compliance was associated with declines in the incidence of HA-SAB (incidence rate ratio 0·85; 95% CI 0·79–0·93; p≤0·0001): for every 10% increase in hand hygiene compliance, the incidence of HA-SAB decreased by 15%.

Interpretation

The NHHI has been associated with significant sustained improvement in hand hygiene compliance and a decline in the incidence of HA-SAB. Key features include sustained central coordination of a standardised approach and incorporation into hospital accreditation standards. The NHHI could be emulated in other national culture-change programmes.

Abstract

We report an Elizabethkingia anophelis case cluster associated with contaminated aerators and tap water in a children’s intensive care unit in Singapore in 2017. We demonstrate a likely transmission route for E. anophelis to patients through acquisition of the bacteria on hands of healthcare workers via handwashing.

Abstract

Background:

Information on the impact of hygiene interventions on severe outcomes is limited. As a pre-specified secondary outcome of a cluster-randomized controlled trial among >400 000 low-income residents in Dhaka, Bangladesh, we examined the impact of cholera vaccination plus a behaviour change intervention on diarrhoea-associated hospitalization.

Methods:

Ninety neighbourhood clusters were randomly allocated into three areas: cholera-vaccine-only; vaccine-plus-behaviour-change (promotion of hand-washing with soap plus drinking water chlorination); and control. Study follow-up continued for 2 years after intervention began. We calculated cluster-adjusted diarrhoea-associated hospitalization rates using data we collected from nearby hospitals, and 6-monthly census data of all trial households.

Results:

A total of 429 995 people contributed 500 700 person-years of data (average follow-up 1.13 years).Vaccine coverage was 58% at the start of analysis but continued to drop due to population migration. In the vaccine-plus-behaviour-change area, water plus soap was present at 45% of hand-washing stations; 4% of households had detectable chlorine in stored drinking water. Hospitalization rates were similar across the study areas [events/1000 person-years, 95% confidence interval (CI), cholera-vaccine-only: 9.4 (95% CI: 8.3–10.6); vaccine-plus-behaviour-change: 9.6 (95% CI: 8.3–11.1); control: 9.7 (95% CI: 8.3–11.6)]. Cholera cases accounted for 7% of total number of diarrhoea-associated hospitalizations.

Conclusions:

Neither cholera vaccination alone nor cholera vaccination combined with behaviour-change intervention efforts measurably reduced diarrhoea-associated hospitalization in this highly mobile population, during a time when cholera accounted for a small fraction of diarrhoea episodes. Affordable community-level interventions that prevent infection from multiple pathogens by reliably separating faeces from the environment, food and water, with minimal behavioural demands on impoverished communities, remain an important area for research.

Key Messages

  • Neither cholera vaccination alone nor cholera vaccination combined with hand-washing and water treatment promotion measurably reduced diarrhoea-associated hospitalization.
  • The possible reasons for lack of impact of cholera vaccine alone on all-cause diarrhoea hospitalization were: cholera incidence was too low during the study period; and high migration rate diluted cholera vaccination coverage of the intervention areas during the period of the analysis.
  • The reason for the lack of impact of the behavioural intervention on diarrhoea-associated hospitalization may have been because of the low uptake.
  • Affordable community-level interventions that prevent infection from multiple pathogens by reliably separating faeces from the environment, food and water in impoverished communities remain an important area for research.

Highlights

  • We review the effectiveness of PPMs against pandemic influenza infection.
  • Hand hygiene provided a significant protective effect.
  • Facemask use provided a non-significant protective effect.
  • No data were found on the effectiveness of cough etiquette.

 

Abstract

The goal of this review was to examine the effectiveness of personal protective measures in preventing pandemic influenza transmission in human populations.

We collected primary studies from Medline, Embase, PubMed, Cochrane Library, CINAHL and grey literature. Where appropriate, random effects meta-analyses were conducted using inverse variance statistical calculations.

Meta-analyses suggest that regular hand hygiene provided a significant protective effect (OR = 0.62; 95% CI 0.52–0.73; I2 = 0%), and facemask use provided a non-significant protective effect (OR = 0.53; 95% CI 0.16–1.71; I2 = 48%) against 2009 pandemic influenza infection. These interventions may therefore be effective at limiting transmission during future pandemics.

Abstract

To prevent Ebola transmission, frequent handwashing is recommended in Ebola Treatment Units and communities. However, little is known about which handwashing protocol is most efficacious. We evaluated six handwashing protocols (soap and water, alcohol-based hand sanitizer (ABHS), and 0.05% sodium dichloroisocyanurate, high-test hypochlorite, and stabilized and non-stabilized sodium hypochlorite solutions) for 1) efficacy of handwashing on the removal and inactivation of non-pathogenic model organisms and, 2) persistence of organisms in rinse water. Model organisms E. coli and bacteriophage Phi6 were used to evaluate handwashing with and without organic load added to simulate bodily fluids. Hands were inoculated with test organisms, washed, and rinsed using a glove juice method to retrieve remaining organisms. Impact was estimated by comparing the log reduction in organisms after handwashing to the log reduction without handwashing. Rinse water was collected to test for persistence of organisms. Handwashing resulted in a 1.94–3.01 log reduction in E. coli concentration without, and 2.18–3.34 with, soil load; and a 2.44–3.06 log reduction in Phi6 without, and 2.71–3.69 with, soil load. HTH performed most consistently well, with significantly greater log reductions than other handwashing protocols in three models. However, the magnitude of handwashing efficacy differences was small, suggesting protocols are similarly efficacious. Rinse water demonstrated a 0.28–4.77 log reduction in remaining E. coli without, and 0.21–4.49 with, soil load and a 1.26–2.02 log reduction in Phi6 without, and 1.30–2.20 with, soil load. Chlorine resulted in significantly less persistence of E. coli in both conditions and Phi6 without soil load in rinse water (p<0.001). Thus, chlorine-based methods may offer a benefit of reducing persistence in rinse water. We recommend responders use the most practical handwashing method to ensure hand hygiene in Ebola contexts, considering the potential benefit of chlorine-based methods in rinse water persistence.

Abstract

Norovirus (NoV) epidemics normally peak in December in Japan; however, the peak in the 2009-2010 season was delayed until the fourth week of January 2010. We suspected intensive hand hygiene that was conducted for a previous pandemic influenza in 2009 as the cause of this delay. We analysed the NoV epidemic trend, based on national surveillance data, and its associations with monthly output data for hand hygiene products, including alcohol-based skin antiseptics and hand soap. The delayed peak in the NoV incidence in the 2009-2010 season had the lowest number of recorded cases of the five seasons studied (2006-2007 to 2010-2011). GII.4 was the most commonly occurring genotype. The monthly relative risk of NoV and monthly output of both alcohol-based skin antiseptics and hand soap were significantly and negatively correlated. Our findings suggest an association between hand hygiene using these products and prevention of NoV transmission.

Summary

Hand hygiene is an important component of infection control, which is critical to ensuring patients’ safety in hospitals. Nursing students are regarded as healthcare workers in training and can also be vehicles of cross-contamination within the hospital. Thus, this study aimed to identify the predictors of hand hygiene practice among Saudi nursing students. A descriptive, cross-sectional, self-reported study was conducted among 198 Saudi nursing students. Knowledge, attitude, and practice of hand hygiene were assessed using the WHO Hand Hygiene Knowledge Questionnaire for Health-Care Workers and its adopted scales. A regression analysis was performed to identify the predictors of hand hygiene practice. The respondents demonstrated moderate knowledge of hand hygiene (mean 13.20 ± 2.80). The majority displayed a moderate attitude toward hand hygiene (52.1%), while only a few reported a poor attitude (13.1%). Approximately 68.7%, 29.8%, and 1.5% of the respondents reported moderate, good, and poor practice of hand hygiene, respectively. Having a good attitude toward hand hygiene, being male, being aware that hand hygiene is an effective intervention in preventing healthcare-associated infections (HAIs), attendance at hand hygiene trainings and seminars, and being in the lower academic level of nursing education were identified as predictors of better hand hygiene practice. The importance of ensuring a positive attitude toward hand hygiene and improving awareness of hand hygiene is emphasized, as are educational interventions. Educational interventions should be implemented to reinforce knowledge and instill a positive attitude toward hand hygiene.
