Compliance with hand disinfection and its impact on hospital-acquired infections

S2k-Guideline hand antisepsis and hand hygiene

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

Determinants of hand hygiene compliance among healthcare workers in intensive care units: a qualitative study

BACKGROUND

Practicing hand hygiene is a cost-effective method to decrease the occurrence of Healthcare-Associated Infections (HAIs). However, despite their simplicity, adhering to hand hygiene methods among healthcare workers (HCWs) can be highly challenging. We aim to examine the factors influencing hand hygiene compliance as perceived by HCWs working in the intensive care units (ICUs) at several major hospitals in Riyadh, Saudi Arabia.

METHOD

This qualitative study was conducted by adopting a content analysis to examine the interviews of HCWs who are currently working in the ICUs of various major hospitals located in the capital city of Riyadh, Saudi Arabia.

RESULTS

We interviewed 49 HCWs working in ICUs, with an average age of 38 and 8 years of experience. The HCWs comprised doctors (n = 12), anesthesiologists (n = 6), and nurses (n = 31). There were 34 females and 15 males among the participants. Our analysis revealed several factors that impact hand hygiene compliance, including individual, work/environment, team, task, patient, organizational, and management concerns. Several obstacles and possibilities for enhancement have been identified.

CONCLUSION

The results of this study would enhance our comprehension of hand hygiene practices and serve as a foundation for creating future strategies and assessment methods to enhance compliance with hand hygiene protocols in ICUs.

Evaluating the tolerability and acceptability of a locally produced alcohol-based handrub and hand hygiene behaviour among health workers in Sierra Leone: a longitudinal hospital-based intervention study

BACKGROUND

Alcohol-based handrub (ABHR) is the gold standard for hand hygiene (HH) and is a cornerstone of infection prevention and control (IPC) strategies. However, several factors influence the efficient use of ABHR by health workers. This study evaluated the tolerability and acceptability of a locally produced ABHR product and HH behaviour among health workers.

METHODS

A longitudinal hospital-based intervention study was conducted in accordance with the WHO's standardized protocol for evaluating ABHR tolerability and acceptability (Method 1). Sixty health workers across 4 hospitals in Sierra Leone were observed over a 30-day period at three separate visits (days 1, 3-5, and 30) by trained observers. The outcomes of interest included skin tolerability and product acceptabilityevaluated using subjective and objective measures.

RESULTS

Objective and subjective evaluations demonstrated strong skin tolerability and high acceptability with the product. At all three visits, the skin tolerability score assessed by trained observers was < 2 in ≥ 97% of participants, exceeding the WHO benchmark score (BMS = < 2 in ≥ 75%). Participants' self-evaluations of overall skin integrity were 97% (visit 2) and 98% (visit 3) for scores > 4 (BMS = > 4 in ≥ 75%). The primary acceptability criteria increased up to 95% (colour) and 88% (smell) at visit 3 (BMS = > 4 in ≥ 50%). Despite high acceptability, the product's drying effect remained low at 52% and 58% during visits 2 and 3, respectively (BMS = > 4 in ≥ 75%). There were positive HH behaviours (n = 53, 88%), with more than half (n = 38, 63%) of them exhibiting HH at almost every HH moment. The mean ABHR was notably high (76.1 ml, SD ± 35), especially among nurses (mean = 80.1 ml) and doctors (mean = 74.0 ml).

CONCLUSION

The WHO-formulated, locally produced ABHR was well tolerated and accepted by health workers. These findings support the continuous utilization of evidence-based, cost-effective hand hygiene interventions in resource-limited settings. High handrub consumption and frequent HH practices were noticeable HH behaviours. Further research is recommended to optimize product formulations for skin dryness and investigate the association between ABHR consumption and hand hygiene compliance.

Workflows and locations matter - insights from electronic hand hygiene monitoring into the use of hand rub dispensers across diverse hospital wards

Background

While healthcare-associated infections (HAIs) affect approximately 3.2-6.5% of hospitalised patients in the US and Europe, improving hand hygiene (HH) could reduce HAI rates. Investigating HH is time-consuming and not always objective, and comprehensive, unbiased data is needed to develop effective strategies. Using electronic tools can provide new and detailed insights on the determinants of HH.

Aim

To evaluate location-dependent usage of wall-mounted dispensers (WMDs) and point-of-care dispensers (POCs) using an electronic HH recording system.

Methods

In this retrospective study, hand rub volumes were anonymously recorded for 931,446 disinfections from 17 wards in nine German hospitals using the electronic monitoring system NosoEx®. Number of disinfections and rub volumes of WMDs/POCs by ward and room type were analysed.

Findings

Generally, WMDs were most prevalent. With >3 dispensers per bed and >20 disinfections per patient day, availability and use were highest in intensive care (ICU) and intermediate care (IMC), but here rub volumes from WMDs were lowest (∼2.0 mL). Although most dispensers are located in patient rooms (∼42%), they are more frequently used in hallways. In surgical ICUs, dispensers are often used in patient rooms, where contact with open wounds is common. About 3.6 mL of hand rub is used per disinfection in treatment rooms, the highest volume of all room types.

Conclusion

Dispenser use was dependent on location, room type, ward specialisation and workflow. Optimising the location of hand rub dispensers (HRDs)s is not the only solution to improve HH, but can help reduce inconvenience, achieve more ergonomic workflows and better meet user needs.

Knowledge and practice of infection control during radiology procedures among radiography undergraduates in Sri Lanka

INTRODUCTION

Sufficient knowledge and adherence to infection control measures are essential for healthcare workers to effectively combat healthcare-associated infections (HCAIs). Radiography undergraduates should stay updated and proficient in their infection control practice. This study aimed to assess knowledge and practice of infection control measures during radiological procedures among radiography undergraduates in Sri Lanka.

METHOD

A web-based, descriptive, self-administered, cross-sectional study was conducted. The questionnaire collected data on demographic, knowledge and practice related to infection control measures from radiography undergraduates.

RESULTS

A total of 167 radiography undergraduates returned the completed questionnaire. The majority (88%) have never participated in infection control programs. The mean knowledge and practice scores were 58% and 41.1%, indicating moderate and poor levels, respectively. A significant difference was observed in the overall knowledge of infection control when considering the academic year (p = 0.001) and the duration of clinical exposure (p = 0.01). There was no significant difference between practice and gender, age, ethnicity, academic year and duration of clinical exposure (p > 0.05).

CONCLUSIONS

The results of this study indicate that knowledge of nosocomial infection was moderate and practice was inadequate among most of the radiography students surveyed. This highlights the need to reassess the educational components of radiography programs to incorporate practical and comprehensive teaching, learning and monitoring of infection control measures.

Educational intervention to improve infection prevention and control practices in four companion animal clinics in Switzerland

BACKGROUND

Infection prevention and control (IPC) practices vary among companion animal clinics, and outbreaks with carbapenemase-producing Enterobacterales (CPE) have been described.

AIM

To investigate the effect of an IPC intervention (introduction of IPC protocols, IPC lectures, hand hygiene campaign) in four companion animal clinics.

METHODS

IPC practices, environmental and hand contamination with antimicrobial-resistant micro-organisms (ARM) and hand hygiene (HH) were assessed at baseline, and 1 and 5 months after the intervention.

RESULTS

Median IPC scores (% maximum score) improved from 57.8% (range 48.0-59.8%) to 82.9% (range 81.4-86.3%) at 1-month follow-up. Median cleaning frequency assessed by fluorescent tagging increased from 16.7% (range 8.9-18.9%) to 30.6% (range 27.8-52.2%) at 1-month follow-up and 32.8% (range 32.2-33.3%) at 5-month follow-up. ARM contamination was low in three clinics at baseline and undetectable after the intervention. One clinic showed extensive contamination with ARM including CPE before and after the intervention (7.5-16.0% ARM-positive samples and 5.0-11.5% CPE-positive samples). Mean HH compliance improved from 20.9% [95% confidence interval (CI) 19.2-22.8%] to 42.5% (95% CI 40.4-44.7%) at 1-month follow-up and 38.7% (95% CI 35.7-41.7%) at 5-month follow-up. Compliance was lowest in the pre-operative preparation area at baseline (11.8%, 95% CI 9.3-14.8%) and in the intensive care unit after the intervention (28.8%, 95% CI 23.3-35.1%). HH compliance was similar in veterinarians (21.5%, 95% CI 19.0-24.3%) and nurses (20.2%, 95% CI 17.9-22.7%) at baseline, but was higher in veterinarians (46.0%, 95% CI 42.9-49.1%) than nurses (39.0%, 95% CI 36.0-42.1%) at 1-month follow-up.

CONCLUSION

The IPC intervention improved IPC scores, cleaning frequency and HH compliance in all clinics. Adapted approaches may be needed in outbreak situations.

Implications of Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) Infected Hospitalised Patients with Co-Infections and Clinical Outcomes

The clinical severity of Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) infection may rise because of acquiring a co-infection during the hospital stay of the patients. The rate of hospital co-infection alongside COVID-19 infection remains low. However, the mortality rates and intensive care unit (ICU) admission remains ambiguous. The present study investigates the implications of COVID-19 hospitalised infected patients with co-infection and the clinical outcomes. In this study, 142 patients were included. The eligible patients who tested positive for COVID-19 infection were hospitalised for more than two days. Each patient's characteristics and laboratory results were collected, such as who was admitted to the intensive care unit and who was discharged or expired. The results revealed that out of the 142 hospitalised patients, 25 (17.6%) were co-infection positive, and 12 identified types of co-infection: two Gram-positive bacterial infections, one fungal infection and nine Gram-negative bacterial infections. In addition, 33 (23.2%) were ICU admitted, 21 were co-infection negative and 12 were co-infection positive. Among the 12 ICU admitted with co-infection, 33.4% were discharged. The death rate and ICU admission had a p-value < 0.05, indicating statistical significance for co-infected patients compared to non-co-infected patients. It was concluded that co-infection remains very low within hospitalised COVID-19-infected patients but can have severe outcomes with increased ICU admission and increased mortality rates. Thus, implementing infection preventive measures to minimize the spread of hospital-acquired infections among COVID-19 hospitalised patients.

Using nudges to promote clinical decision making of healthcare professionals: A scoping review

Nudging has been discussed in the context of policy and public health, but not so much within healthcare. This scoping review aimed to assess the empirical evidence on how nudging techniques can be used to affect the behavior of healthcare professionals (HCPs) in clinical settings. A systematic database search was conducted for the period January 2010-December 2020 using the PRISMA extension for Scoping Review checklist. Two reviewers independently screened each article for inclusion. Included articles were reviewed to extract key information about each intervention, including purpose, target behavior, measured outcomes, key findings, nudging strategies, intervention objectives and their theoretical underpinnings. Two independent dimensions, building on Kahneman's System 1 and System 2, were used to describe nudging strategies according to user action and timing of their implementation. Of the included 51 articles, 40 reported statistically significant results, six were not significant and two reported mixed results. Thirteen different nudging strategies were identified aimed at modifying four types of HPCs' behavior: prescriptions and orders, procedure, hand hygiene, and vaccination. The most common nudging strategy employed were defaults or pre-orders, followed by alerts or reminders, and active choice. Many interventions did not require any deliberate action from users, here termed passive interventions, such as automatically changing prescriptions to their generic equivalent unless indicated by the user. Passive nudges may be successful in changing the target outcome but may go unnoticed by the user. Future work should consider the broader ethical implications of passive nudges.

Health Care Workers' Adherence to Hand Hygiene Guidelines in Emergency Surgical Room of a Tertiary Care Hospital

Background  Out of every 100 hospitalized patients, 7 patients in advanced countries and 10 patients in emerging countries acquire health care-associated infections (HCAIs). Hand hygiene (HH) procedures are the simple and cost-effective solution to significantly reduce HCAI. We wanted to know the compliance rate of HH procedures among health care workers (HCWs) working in emergency surgical room (ESR) of our institute, so that feedback can be given to them and further interventions can be planned.

Methodology  This is a cross-sectional observational study conducted in ESR. Resident doctors and faculties, interns, and nurses were directly observed for all the five moments of HH recommended by World Health Organization (WHO). The data have been recorded with the WHO recommended form for observation and basic compliance calculation for HH.

Results  In total, 1,370 HH opportunities were observed and recorded, of which 690 were for resident doctors and faculties, and 340 each for interns and nurses. The overall total HH compliance rate among all HCWs was 41.3% and resident doctors and faculties had the poorest compliance. Poorest compliance was observed for moment 1, whereas maximum compliance was for moment 3 among all the HCWs.

Conclusion  HCWs' adherence to HH guidelines in ESR of this tertiary care hospital is low and is least in resident doctors and faculties.

Approaches to multidrug-resistant organism prevention and control in long-term care facilities for older people: a systematic review and meta-analysis

BACKGROUND

Despite clear evidence of benefits in acute-care hospitals, controversy over the effectiveness of IPC measures for MDROs is perceptible and evidence-based practice has not been established.

OBJECTIVE

To investigate the effects of IPC interventions on MDRO colonization and infections in LTCFs.

DATA SOURCES

Ovid MEDLINE, EMBASE, and CINAHL from inception to September 2020.

ELIGIBILITY CRITERIA

Original and peer-reviewed articles examining the post-intervention effects on MDRO colonization and infections in LTCFs.

INTERVENTIONS

(i) Horizontal interventions: administrative engagement, barrier precautions, education, environmental cleaning, hand hygiene, performance improvement, and source control; and (ii) vertical intervention: active surveillance plus decolonization.

STUDY APPRAISAL AND SYNTHESIS

We employed a random-effects meta-analysis to estimate the pooled risk ratios (pRRs) for methicillin-resistant Staphylococcus aureus (MRSA) colonization by intervention duration; and conducted subgroup analyses on different intervention components. Study quality was assessed using Cochrane risk of bias tools.

RESULTS

Of 3877 studies identified, 19 were eligible for inclusion (eight randomized controlled trials (RCTs)). Studies reported outcomes associated with MRSA (15 studies), vancomycin-resistant Enterococci (VRE) (four studies), Clostridium difficile (two studies), and Gram-negative bacteria (GNB) (two studies). Eleven studies were included in the meta-analysis. The pRRs were close to unity regardless of intervention duration (long: RR 0.81 [95% CI 0.60-1.10]; medium: RR 0.81 [95% CI 0.25-2.68]; short: RR 0.95 [95% CI 0.53-1.69]). Vertical interventions in studies with a small sample size showed significant reductions in MRSA colonization while horizontal interventions did not. All studies involving active administrative engagement reported reductions. The risk of bias was high in all but two studies.

CONCLUSIONS

Our meta-analysis did not show any beneficial effects from IPC interventions on MRSA reductions in LTCFs. Our findings highlight that the effectiveness of interventions in these facilities is likely conditional on resource availability-particularly decolonization and barrier precautions, due to their potential adverse events and uncertain effectiveness. Hence, administrative engagement is crucial for all effective IPC programmes. LTCFs should consider a pragmatic approach to reinforce standard precautions as routine practice and implement barrier precautions and decolonization to outbreak responses only.

Association between nursing work stress, burnout and nosocomial infection rate in a neonatal intensive care unit in Hargeisa, Somaliland

Our study looks at the effects of burnout and stress levels of nurses, behaviour regarding medical waste, and other effective risk factors on the first time and recurrent diagnosis of nosocomial infection (NI) in neonatal intensive care units in Hargeisa, Somaliland. This multicentric follow-up study was conducted and repeated measurements were taken from 72 neonates and 45 nurses working in three hospitals for a period of five months. Nurses with high burnout levels had 3.7 times higher risk of neonates under their care being diagnosed with an NI (odds ratio: 3.743; 95% CI: 1.498-9.356). By controlling other variables, the stress level of nurses increased the incidence rate of neonates being diagnosed more than once with NI by 3.2 times. Statistically, the direction of causal association was from the high burnout among nurses to the diagnosis of NI, and high stress was associated with the recurrent diagnosis of infections in neonates.

The Era of Coronavirus: Knowledge, Attitude, Practices, and Barriers to Hand Hygiene Among Makerere University Students and Katanga Community Residents

BACKGROUND

The Novel Coronavirus was declared as a pandemic by the WHO at the end of 2019. Proper hand hygiene was identified as one of the simplest most cost-effective Covid-19 control and prevention measures. It is therefore very important to identify gaps in the knowledge, attitude, and practices, and barriers regarding hand hygiene in the community.

METHODS

A descriptive cross-sectional study was conducted using a simple random sampling technique. An interviewer-guided questionnaire with questions on knowledge, attitude, practice, and barriers to hand hygiene was used in data collection. Collected data were analyzed using Microsoft office excel 2016 and STATA 15 software. A 95% confidence interval was used and statistical significance was P<0.05.

RESULTS

Only 88 (24.5%) of the participants had adequate knowledge of hand hygiene. 32.8% of the university students had adequate knowledge compared to 6.3% of the Katanga residents. The majority of 336 (93.6%) participants had a good attitude towards hand hygiene. University students had a significantly better knowledge of hand hygiene while Katanga slum residents had a slightly better attitude towards hand hygiene. Only 19.6% accomplished all the seven steps of handwashing. 38.4% of the participants were still greeting by handshaking. Of the participants, 60.1% noted lack of soap as a barrier to hand hygiene and 62.9% reported having more than three barriers to hand hygiene. Participants who had been taught handwashing were more likely to have better hand hygiene knowledge and practice.

CONCLUSION

There was an overall high proportion of participants with a low level of hand hygiene knowledge. There is a need for optimizing hand-hygiene practices through addressing the barriers and promoting public health education.

Nudging healthcare professionals in clinical settings: a scoping review of the literature

BACKGROUND

Healthcare organisations are in constant need of improvement and change. Nudging has been proposed as a strategy to affect people's choices and has been used to affect patients' behaviour in healthcare settings. However, little is known about how nudging is being interpreted and applied to change the behaviour of healthcare professionals (HCPs). The objective of this review is to identify interventions using nudge theory to affect the behaviour of HCPs in clinical settings.

METHODS

A scoping review. We searched PubMed and PsycINFO for articles published from 2010 to September 2019, including terms related to "nudging" in the title or abstract. Two reviewers screened articles for inclusion based on whether the articles described an intervention to change the behaviour of HCPs. Two reviewers extracted key information and categorized included articles. Descriptive analyses were performed on the data.

RESULTS

Search results yielded 997 unique articles, of which 25 articles satisfied the inclusion criteria. Five additional articles were selected from the reference lists of the included articles. We identified 11 nudging strategies: accountable justification, goal setting, suggested alternatives, feedback, information transparency, peer comparison, active choice, alerts and reminders, environmental cueing/priming, defaults/pre-orders, and education. These strategies were employed to affect the following 4 target behaviours: vaccination of staff, hand hygiene, clinical procedures, prescriptions and orders. To compare approaches across so many areas, we introduced two independent dimensions to describe nudging strategies: synchronous/asynchronous, and active/passive.

CONCLUSION

There are relatively few studies published referring to nudge theory aimed at changing HCP behaviour in clinical settings. These studies reflect a diverse set of objectives and implement nudging strategies in a variety of ways. We suggest distinguishing active from passive nudging strategies. Passive nudging strategies may achieve the desired outcome but go unnoticed by the clinician thereby not really changing a behaviour and raising ethical concerns. Our review indicates that there are successful active strategies that engage with clinicians in a more deliberate way. However, more research is needed on how different nudging strategies impact HCP behaviour in the short and long term to improve clinical decision making.

Hydrogels in Hand Sanitizers

Hand hygiene can be considered a strategic key useful in the containment of infections such as COVID-19 both at home and in communities because it can dramatically reduce the widespread outbreak of infections. In case of the unavailability of soap and water, "instant" hand sanitizers are recommended because their application can be considered easy, versatile, quick and often less aggressive for the skin. For these reasons, alcoholic and alcohol-free hand rub gels can be considered the best performing formulations on the market. Together with disinfectants and antiseptic agents, hydrogels play a fundamental role in obtaining stable formulations and are easy to disperse, with a pleasant skin feel and an overall good performance. Several compounds commonly used in the pharmaceutical, cosmetic and food industry are available for this purpose, in particular, cellulose derivatives and synthetic polymers derivatives. Each of them is available in several grades, presenting different thickening behavior, rheological properties and compatibility with other ingredients, alcohols in particular. For all these reasons, it is important to explore hydrogel properties and behaviors in different contexts (i.e., hydroalcoholic and aqueous media) in order to develop new and performing hand rub gels, always taking into account the different international legal frameworks regarding disinfectant and sanitizing formulations.

Risk Factors and Effects of the Morbus: COVID-19 through the Biopsychosocial Model and Ecological Systems Approach to Social Work Practice

Utilizing the biopsychosocial model and the ecological systems theory, this disquisition explores on the risk factors associated with the COVID-19 pandemic. The discourse shows the interconnectedness of biological, psychological, and social domains in expatiating on the COVID-19 pandemic. It calls for the need to strengthen the resilience of the global community in the face of health outbreaks such as COVID-19. It emphasizes on the perspectives that pandemics are managed before they emerge through building systems that are resilient. Thus, it appreciates the need for a therapeutic milieu as a building block to resilience. The article calls for the adoption of a developmental stance to analyzing health outbreaks and clinical issues. The adumbration shows the reciprocity effects of the health outbreak [macrocosms] and individual factors [microcosms]. To its end, the paper implies that COVID-19 is a call for integration toward effective health planning between social policy formulators, urban and rural planners, epidemiologists, development practitioners, clinicians, researchers to mention but a few. Ultimately, the paper calls for social workers to consider a developmental-clinical social work approach which helps foster "health in all policies" so as to build resilience against the morbus and limit the proliferation of diseases.

Patient education on infection control: A systematic review

BACKGROUND

Lately, suggestions have been emphasizing the importance of engaging patients and family members in infection control (IC) through participation and education after showing that patients and family members can aid in preventing the transmission of health care-associated infections. However, assessing patient education on IC measures in hospitals is poorly investigated.

PURPOSE

To identify all available studies in the literature that assessed hospitalized patients' education on IC measures.

METHODS

PubMed, Embase, and CINAHL were searched from inception till May 6, 2020 without restrictions. We used Strengthening the Reporting of Observational Studies in Epidemiology tool for assessing the reporting quality of each eligible study.

MAIN FINDINGS

Of the 6,740 identified papers, 25 were eligible for inclusion. Education on health care-associated infections was investigated in 8 studies, education on central line-associated bloodstream infections in 1, education on surgical site infections in 2, education on hand hygiene in 12, education on isolation rationale, precautions, usage of personal protective equipment in 3, and education on respiratory hygiene in 1. In general, a low percentage of patient education on IC was found in most of the included papers.

CONCLUSIONS

The low percentage of patient education on IC in hospitals highlights the need for additional emphasis on patient involvement in IC. Further studies are needed to assess patient education on several IC measures and to explore the education of family members as well.

Hand hygiene compliance in Dutch general practice offices

BACKGROUND

Hand hygiene (HH) is considered one of the most important measures to prevent healthcare-associated infections (HAI). Most studies focus on HH compliance within the hospital setting, whereas little is known for the outpatient setting. The aim of this study was to evaluate compliance with HH recommendations in general practitioners (GPs) office, based on World Health Organization (WHO) guideline.

METHODS

An observational study was conducted at five Dutch GPs-practices in September 2017. We measured HH compliance through direct observation using WHO's 'five moments of hand hygiene' observation tool. All observations were done by one trained professional.

RESULTS

We monitored a total of 285 HH opportunities for 30 health care workers (HCWs). The overall compliance was 37%. Hand hygiene compliance was 34, 51 and 16% for general practitioners, practice assistants, and nurses, respectively. It varies between 63% after body fluid exposure and no HH performance before-, during and after home visit of a patient (defined as moment 5). The preferred method of HH was soap and water (63%) versus 37% for alcohol-based hand rub (ABHR). The median time of disinfecting hands was 8 s (range 6-11 s) for HCWs in our study.

CONCLUSIONS

HH compliance among HCWs in Dutch GPs was found to be low, especially with regard to home visits. The WHO recommended switch from hand wash to ABHR was not implemented by the majority of HCWs in 5 observed GPs offices.

Role of pulsed-xenon ultraviolet light in reducing healthcare-associated infections: a systematic review and meta-analysis

Pulsed-xenon-ultraviolet light (PX-UVL) is increasingly used as a supplemental disinfection method in healthcare settings. We undertook a systematic search of the literature through several databases and conducted a meta-analysis to evaluate the efficacy of PX-UVL in reducing healthcare-associated infections. Eleven studies were included in the systematic review and nine in the meta-analysis. Pooled analysis of seven studies with before-after data indicated a statistically significant reduction of Clostridium difficile infection (CDI) rates with the use of the PX-UVL (incidence rate ratio (IRR): 0.73, 95% CI 0.57–0.94, I² = 72%, P = 0.01), and four studies reported a reduction of risk of methicillin-resistant Staphylococcus aureus (MRSA) infections (IRR: 0.79, 95% CI 0.64–0.98, I² = 35%, P = 0.03). However, a further four trials found no significant reduction in vancomycin-resistant enterococci (VRE) infection rates (IRR: 0.80, 95% CI 0.63–1.01, I² = 60%, P = 0.06). The results for CDI and MRSA proved unstable on sensitivity analysis. Meta-regression analysis did not demonstrate any influence of study duration or intervention duration on CDI rates. We conclude that the use of PX-UVL, in addition to standard disinfection protocols, may help to reduce the incidence of CDI and MRSA but not VRE infection rates. However, the quality of evidence is not high, with unstable results and wide confidence intervals, and further high-quality studies are required to supplement the current evidence.

The role of environmental factors to transmission of SARS-CoV-2 (COVID-19)

The current outbreak of the novel coronavirus disease 2019 (COVID-19) in more than 250 countries has become a serious threat to the health of people around the world. Human-to-human transmission of the Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) occurs most often when people are in the incubation stage of the disease or are carriers and have no symptoms. Therefore, in this study, was discussed the role of environmental factors and conditions such as temperature, humidity, wind speed as well as food, water and sewage, air, insects, inanimate surfaces, and hands in COVID-19 transmission. The results of studies on the stability of the SARS-CoV-2 on different levels showed that the resistance of this virus on smooth surfaces was higher than others. Temperature increase and sunlight can facilitate the destruction of SARS-COV-2 and the stability of it on surfaces. When the minimum ambient air temperature increases by 1 °C, the cumulative number of cases decreases by 0.86%. According to the latest evidence, the presence of coronavirus in the sewer has been confirmed, but there is no evidence that it is transmitted through sewage or contaminated drinking water. Also, SARS-COV-2 transmission through food, food packages, and food handlers has not been identified as a risk factor for the disease. According to the latest studies, the possibility of transmitting SARS-COV-2 bioaerosol through the air has been reported in the internal environment of ophthalmology. The results additionally show that infectious bio-aerosols can move up to 6 feet. There have been no reports of SARS-COV-2 transmission by blood-feeding arthropods such as mosquitoes.

Hand Sanitizers: A Review on Formulation Aspects, Adverse Effects, and Regulations

Hand hygiene is of utmost importance as it may be contaminated easily from direct contact with airborne microorganism droplets from coughs and sneezes. Particularly in situations like pandemic outbreak, it is crucial to interrupt the transmission chain of the virus by the practice of proper hand sanitization. It can be achieved with contact isolation and strict infection control tool like maintaining good hand hygiene in hospital settings and in public. The success of the hand sanitization solely depends on the use of effective hand disinfecting agents formulated in various types and forms such as antimicrobial soaps, water-based or alcohol-based hand sanitizer, with the latter being widely used in hospital settings. To date, most of the effective hand sanitizer products are alcohol-based formulations containing 62%-95% of alcohol as it can denature the proteins of microbes and the ability to inactivate viruses. This systematic review correlated with the data available in Pubmed, and it will investigate the range of available hand sanitizers and their effectiveness as well as the formulation aspects, adverse effects, and recommendations to enhance the formulation efficiency and safety. Further, this article highlights the efficacy of alcohol-based hand sanitizer against the coronavirus.

Assessment of tolerability and acceptability of an alcohol-based hand rub according to a WHO protocol and using apparatus tests

Background

The effectiveness of alcohol-based hand rubs (ABHRs) depends substantially on their acceptability and tolerability. In this study, we assessed the acceptability and tolerability of a new ABHR (product EU 100.2018.02).

Methods

Among physicians, nurses, and cosmetologists who used the ABHR for 30 days, we assessed the product's acceptability and tolerability according to a WHO protocol. Additionally, we used instrumental skin tests. Participants assessed the product's color, smell, texture, irritation, drying effect, ease of use, speed of drying, and application, and they gave an overall evaluation. Moreover, they rated the tolerability, i.e. their skin condition, on the following dimensions: intactness, moisture content, sensation, and integrity of the skin. The tolerability was also assessed by an observer as follows: redness, scaliness, fissures, and overall score for the skin condition. Instrumental skin tests included transepidermal water loss, skin hydration, sebum secretion, and percentage of skin affected by discolorations. All assessments were made at baseline (visit 1), and 3-5 days (visit 2) and 30 days (visit 3) later.

Results

We enrolled 126 participants (110 [87%] women) with a mean age of 34.3 ± 11.65 years. Sixty-five participants (52%) were healthcare professionals (physicians, nurses), and 61 (48%) were cosmetologists. During visit 2 and visit 3, about 90% of participants gave responses complying with the WHO's benchmark for acceptability and tolerability. Similarly, the ABHR met the WHO criteria for observer-assessed tolerability: on all visits, in more than 95% of participants, the observer gave scores complying with the WHO benchmark. Transepidermal water loss decreased from baseline to visit 3 (p < 0.001), whereas skin hydration, sebum secretion, and the percentage of skin affected by discolorations did not change significantly during the study (p ≥ 130).

Conclusions

The EU 100.2018.02 had both high acceptability and tolerability, meeting the WHO criteria. The WHO protocol proved useful in the analysis of acceptability and tolerability of ABHRs.

Assessment of the Risk Factors of Multidrug-Resistant Organism Infection in Adults With Type 1 or Type 2 Diabetes and Diabetic Foot Ulcer

OBJECTIVES

To our knowledge, this is the first review to analyze the literature identifying risk factors for multidrug-resistant organism (MDRO) infection in patients with diabetic foot ulcer. The purpose of this study was to collect the currently published data to determine the most commonly and consistently identified risk factors for MDRO infection.

METHODS

PubMed, MEDLINE, BIOSIS, Web of Science and the Cochrane Library electronic databases were searched. The last search updated was in September 2019. The evaluated outcomes included age, male sex, type of diabetes, diabetes duration, level of glycated hemoglobin, ulcer type, wound duration, ulcer size, ulcer grade, osteomyelitis, previous antibiotic therapy and previous hospitalization. The standard mean difference or the odds ratio (OR) was calculated for continuous or dichotomous data, respectively. The quality of the studies was assessed, and meta-analyses were performed with Cochrane Collaboration's RevMan 5.0 software.

RESULTS

A total of 11 studies, including 1,229 patients provided evidence for 6 possible risk factors for MDRO infection. Ischemic ulcer (OR, 0.50; 95% confidence interval [CI], 0.35 to 0.71), ulcer size (standard mean difference, -0.27; 95% CI, -0.46 to -0.08), ulcer grade (OR, 0.36; 95% CI, 0.15 to 0.83), osteomyelitis (OR, 0.33; 95% CI, 0.25 to 0.45), previous antibiotic therapy (OR, 0.08; 95% CI, 0.04 to 0.14) and previous hospitalization (OR, 0.15; 95% CI, 0.08 to 0.28) were identified as risk factors for MDRO infection in patients with diabetic foot ulcer.

CONCLUSIONS

Our meta-analysis indicated that ischemic ulcer, ulcer size, ulcer grade, osteomyelitis, previous antibiotic therapy and previous hospitalization were associated with MDRO infection in patients with diabetic foot ulcer.

Effect of Frequency of Changing Point-of-Use Reminder Signs on Health Care Worker Hand Hygiene Adherence: A Cluster Randomized Clinical Trial

IMPORTANCE

Although hand hygiene (HH) is considered the most effective strategy for preventing hospital-acquired infections, HH adherence rates remain poor.

OBJECTIVE

To examine whether the frequency of changing reminder signs affects HH adherence among health care workers.

DESIGN, SETTING, AND PARTICIPANTS

This cluster randomized clinical trial in 9 US Department of Veterans Affairs acute care hospitals randomly assigned 58 inpatient units to 1 of 3 schedules for changing signs designed to promote HH adherence among health care workers: (1) no change; (2) weekly; and (3) monthly. Hand hygiene rates among health care workers were documented at entry and exit to patient rooms during the baseline period from October 1, 2014, to March 31, 2015, of normal signage and throughout the intervention period of June 8, 2015, to December 28, 2015. Data analyses were conducted in April 2018.

INTERVENTIONS

Hospital units were randomly assigned into 3 groups: (1) no sign changes throughout the intervention period, (2) signs changed weekly, and (3) signs changed monthly.

MAIN OUTCOMES AND MEASURES

Hand hygiene adherence as measured by covert observation. Interrupted time series analysis was used to examine changes in HH adherence from baseline through the intervention period by group.

RESULTS

Among 58 inpatient units, 19 units were assigned to the no change group, 19 units were assigned to the weekly change group, and 20 units were assigned to the monthly change group. During the baseline period, 9755 HH opportunities were observed at room entry and 10 095 HH opportunities were observed at room exit. During the intervention period, a total of 15 855 HH opportunities were observed at room entry, and 16 360 HH opportunities were observed at room exit. Overall HH adherence did not change from baseline compared with the intervention period at either room entry (4770 HH events [48.9%] vs 3057 HH events [50.1%]; P = .14) or exit (6439 HH events [63.8%] vs 4087 HH events [65.2%]; P = .06). In units that changed signs weekly, HH adherence declined from baseline at room entry (-1.9% [95% CI, -2.7% to -0.8%] per week; P < .001) and exit (-0.8% [95% CI, -1.5% to 0.1%] per week; P = .02). No significant changes in HH adherence were observed in other groups.

CONCLUSIONS AND RELEVANCE

The frequency of changing reminder signs had no effect on HH rates overall. Units assigned to change signs most frequently demonstrated worsening adherence. Considering the abundance of signs in the acute care environment, the frequency of changing signs did not appear to provide a strong enough cue by itself to promote behavioral change.

A multifaceted hand hygiene improvement program on the intensive care units of the National Referral Hospital of Indonesia in Jakarta

Background

Hand hygiene (HH) is considered to be the single most effective measure in preventing healthcare-associated infections. However, HH compliance rates among nurses and doctors in hospitals are often very low. Few studies have addressed HH compliance in Indonesia, performed interventions to increase HH compliance, and none have had long-term follow-up. We, therefore, addressed this issue by performing long-term follow-up after a multifaceted intervention in the intensive care unit (ICU) setting.

Methods

This was an observational, prospective, before-and-after intervention study (May–September 2014, February–April 2017). We measured HH knowledge and HH compliance before (at baseline) and directly after a multifaceted improvement program (post-intervention) and performed a re-evaluation three years later. The multifaceted improvement program included education, feedback, reminders, interviews and the use of role models. The study involved nurses and physicians working in two ICUs of the Dr. Cipto Mangunkusumo Hospital in Jakarta.

Results

A total of 97 at baseline, and 72 at post-intervention HH knowledge questionnaires were completed. There was a statistically significant improvement in the median overall HH knowledge score at post-intervention (from 15 to 22, p < 0.001). There was no significant difference between the two ICUs. The overall HH compliance was 27% at baseline and significantly improved to 77% post-intervention (p < 0.001). For all five HH moments, the compliance of nurses and physicians separately improved significantly from the baseline phase to the post-intervention phase (p < 0.001), except for ‘moment 3’ (after body fluid exposure), for which baseline rates were already high. Most of the compliance rates were significantly lower in both groups of healthcare workers upon follow-up three years later. Overall, the HH compliance of the nurses was significantly better than the physicians’ compliance (p = 0.005).

Conclusions

Our multifaceted improvement program, for nurses and physicians of the ICUs in the largest hospital of Indonesia, resulted in a significant improvement of the HH knowledge and HH compliance, but HH compliance levels waned over time after the intervention, indicating a need for continued monitoring and repeated interventions.

Beyond entry and exit: Hand hygiene at the bedside

BACKGROUND

We aimed to assess compliance, knowledge, and attitudes regarding the World Health Organization (WHO) 5 moments for hand hygiene (HH).

METHODS

We assessed HH compliance from July-August 2016, using a modified WHO HH observation form. A 26-question survey was used to assess health care personnel (HCP) knowledge, opinions, and barriers to HH. A subgroup of HCPs participated in a 2-round focused survey to assign priority to the moments.

RESULTS

Three hundred two HH opportunities were observed in 104 unique HCP-patient interactions. HH was performed at 106 (35%) opportunities, 37% (25 of 68) before touching a patient, 9% (6 of 70) before aseptic procedures, 5% (1 of 22) after body fluid exposure or risk, 63% (55 of 88) after touching a patient, and 35% (19 of 54) after touching patient surroundings. Two hundred eighteen HCPs completed the survey; 63 (29%) were familiar with the WHO 5 moments but only 13 (21%) were able to recall all 5 moments. In the focused surveys, 46% (6 of 13) ranked "before aseptic procedure" as the most important HH moment, and 86% (11 of 13) identified "after touching patient surroundings" as the least important.

CONCLUSIONS

We found frequent opportunities for HH with infrequent compliance. Lack of recognition of opportunities at the bedside and frequent glove use may contribute to lower compliance.

Impact of hand sanitizer format (gel/foam/liquid) and dose amount on its sensory properties and acceptability for improving hand hygiene compliance

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.

Screening of more than 2000 Hungarian healthcare workers' anti-measles antibody level: results and possible population-level consequences

Due to the European measles epidemic and the increased number of imported cases, it can be theorised that the risk of exposure among Hungarian healthcare workers (HCWs) has increased. In 2017, the increased measles circulation in the region led to the emergence of smaller local and hospital epidemics. Therefore, our objective was to determine the herd immunity in the high-risk group of HCWs. A hospital-based study of detecting anti-measles IgG activity was performed in 2017 and included 2167 employees of the Military Medical Centre (Hungary). The screening of HCWs presented a good general seropositivity (90.6%). The highest seroprevalence value (99.1%) was found in the age group of 60 years or older. The lowest number of seropositive individuals was seen in the 41-45 years (86.2%) age group, indicating a significant herd immunity gap between groups. Regarding the Hungarian data, there might be gaps in the seroprevalence of the analysed HCWs, implying that susceptible HCWs may generate healthcare-associated infections. This study suggests that despite the extensive vaccination and high vaccine coverage, it is still important to monitor the level of protective antibodies in HCWs, or in a representative group of the whole population of Hungary, and possibly in other countries as well.

An integrative review exploring the perceptions of patients and healthcare professionals towards patient involvement in promoting hand hygiene compliance in the hospital setting

AIMS AND OBJECTIVES

To review patients' and healthcare professionals' perceptions of patient involvement in promoting hand hygiene compliance in the hospital setting.

BACKGROUND

Initiatives continue to emphasise the importance of involving patients in their safety at the point of care. A patient-centred care approach aimed to empower patients to become active members of the healthcare team. However, understanding the perceptions of patients and healthcare professionals of patient involvement in promoting hand hygiene compliance among healthcare professionals has yet to be fully explored.

DESIGN

Integrative literature review.

METHODS

A five-stage review process informed by Whittemore and Knafl's methodology was conducted. MEDLINE and CINAHL were searched for papers published between January 2009-July 2017. Data were extracted manually, organised using NVivo 11 and analysed using thematic analysis.

RESULTS

From an identified 240 papers, 19 papers were included in this review. Thematic analysis revealed two main themes with three related subthemes. Patients were willing to remind healthcare professionals (especially nurses) to wash their hands, healthcare professionals perception towards patients' involvement varied from one study to another. However, an overall positive attitude towards patient involvement was related to how patients asked and how healthcare professionals responded to being asked.

CONCLUSION

There is limited evidence regarding patients' actual intention to ask healthcare professionals to wash their hands, and some evidence that patients are reluctant to do so. Further research is required to understand this area thoroughly, including which situations patients would feel more empowered to speak up.

RELEVANCE TO CLINICAL PRACTICE

Simple messages promoting patient involvement may lead to complex reactions in both patients and healthcare professionals. It is unclear, yet how patients and staff react to such messages in clinical practice. There is a need for a deeper understanding of how they can work together to support harm free care.

Quantifying the Hawthorne effect using overt and covert observation of hand hygiene at a tertiary care hospital in Saudi Arabia

INTRODUCTION

Although direct human observation of hand hygiene (HH) is considered the gold standard for measuring HH compliance, its accuracy is challenged by the Hawthorne effect.

OBJECTIVES

To compare HH compliance using both overt and covert methods of direct observation in different professional categories, hospital settings, and HH indications.

METHODS

A cross-sectional study was conducted in 28 units at King Abdulaziz Medical City, Riyadh, Saudi Arabia, between October 2012 and July 2013. Compliance was defined as performing handrubbing or handwashing during 1 of the World Health Organization 5 Moments for HH indications (ie, opportunities). Overt observation was done by infection preventionists (IPs) who were doing their routine HH observation. Covert observation was done by unrecognized temporarily hired professionally trained observers.

RESULTS

A total of 15,883 opportunities were observed using overt observation and 7,040 opportunities were observed using covert observation. Overall HH compliance was 87.1% versus 44.9% using overt/covert observations, respectively (risk ratio, 1.94; P < .001). The significant overestimation was seen across all professional categories, hospital settings, and HH indications.

CONCLUSION

There is a considerable difference in HH compliance being observed overtly and covertly in all categories. More work is required to improve the methodology of direct observation to minimize the influence of the Hawthorne effect.

Googling your hand hygiene data: Using Google Forms, Google Sheets, and R to collect and automate analysis of hand hygiene compliance monitoring

BACKGROUND

Hand hygiene is one of the most important interventions in the quest to eliminate healthcare-associated infections, and rates in healthcare facilities are markedly low. Since hand hygiene observation and feedback are critical to improve adherence, we created an easy-to-use, platform-independent hand hygiene data collection process and an automated, on-demand reporting engine.

METHODS

A 3-step approach was used for this project: 1) creation of a data collection form using Google Forms, 2) transfer of data from the form to a spreadsheet using Google Spreadsheets, and 3) creation of an automated, cloud-based analytics platform for report generation using R and RStudio Shiny software.

RESULTS

A video tutorial of all steps in the creation and use of this free tool can be found on our YouTube channel: https://www.youtube.com/watch?v=uFatMR1rXqU&t. The on-demand reporting tool can be accessed at: https://crsp.louisville.edu/shiny/handhygiene.

CONCLUSIONS

This data collection and automated analytics engine provides an easy-to-use environment for evaluating hand hygiene data; it also provides rapid feedback to healthcare workers. By reducing some of the data management workload required of the infection preventionist, more focused interventions may be instituted to increase global hand hygiene rates and reduce infection.

Iterative co-creation for improved hand hygiene and aseptic techniques in the operating room: experiences from the safe hands study

BACKGROUND

Hand hygiene and aseptic techniques are essential preventives in combating hospital-acquired infections. However, implementation of these strategies in the operating room remains suboptimal. There is a paucity of intervention studies providing detailed information on effective methods for change. This study aimed to evaluate the process of implementing a theory-driven knowledge translation program for improved use of hand hygiene and aseptic techniques in the operating room.

METHODS

The study was set in an operating department of a university hospital. The intervention was underpinned by theories on organizational learning, culture and person centeredness. Qualitative process data were collected via participant observations and analyzed using a thematic approach.

RESULTS

Doubts that hand-hygiene practices are effective in preventing hospital acquired infections, strong boundaries and distrust between professional groups and a lack of psychological safety were identified as barriers towards change. Facilitated interprofessional dialogue and learning in "safe spaces" worked as mechanisms for motivation and engagement. Allowing for the free expression of different opinions, doubts and viewing resistance as a natural part of any change was effective in engaging all professional categories in co-creation of clinical relevant solutions to improve hand hygiene.

CONCLUSION

Enabling nurses and physicians to think and talk differently about hospital acquired infections and hand hygiene requires a shift from the concept of one-way directed compliance towards change and learning as the result of a participatory and meaning-making process. The present study is a part of the Safe Hands project, and is registered with ClinicalTrials.gov (ID: NCT02983136 ). Date of registration 2016/11/28, retrospectively registered.

Hand Hygiene: An Update

The medical field has long recognized the importance of hand hygiene in preventing health care-associated infections, yet studies indicate that this important task is performed only 40% of the time. Health care workers cite several barriers to optimal performance of hand hygiene, but the time required to perform this task is foremost among them. Introduction of alcohol-based hand rubs, bundled interventions, and incorporation of technologies designed to monitor and promote hand hygiene all represent promising advances in this field.

Intervening with healthcare workers' hand hygiene compliance, knowledge, and perception in a limited-resource hospital in Indonesia: a randomized controlled trial study

Background

Hand hygiene is recognized as an important measure to prevent healthcare-associated infections. Hand hygiene adherence among healthcare workers is associated with their knowledge and perception. This study aimed to evaluate the effect of three different educational programs on improving hand hygiene compliance, knowledge, and perception among healthcare workers in a tertiary care hospital in Indonesia.

Methods

The study was performed from May to October 2014 and divided into a pre-intervention, intervention, and post-intervention phase. This cluster randomized controlled trial allocated the implementation of three interventions to the departments, including role model training-pediatrics, active presentation-surgery, a combination of role model training and active presentation-internal medicine, and a control group-obstetrics-gynecology. Both direct observation and knowledge-perception survey of hand hygiene were performed using WHO tools.

Results

Hand hygiene compliance was observed during 2,766 hand hygiene opportunities, and knowledge-perception was assessed among 196 participants in the pre-intervention and 88 in the post-intervention period. After intervention, the hand hygiene compliance rate improved significantly in pediatrics (24.1% to 43.7%; P < 0.001), internal medicine (5.2% to 18.5%; P < 0.001), and obstetrics-gynecology (10.1% to 20.5%; P < 0.001). The nurses’ incorrect use of hand rub while wearing gloves increased as well (P < 0.001). The average knowledge score improved from 5.6 (SD = 2.1) to 6.2 (SD = 1.9) (P < 0.05). In the perception survey, “strong smell of hand alcohol” as a reason for non-compliance increased significantly in the departments with intervention (10.1% to 22.9%; P = 0.021).

Conclusion

The educational programs improved the hand hygiene compliance and knowledge among healthcare workers in two out of three intervention departments in a limited-resource hospital in Indonesia. Role model training had the most impact in this setting. However, adjustments to the strategy are necessary to further improve hand hygiene.

Exploring surface cleaning strategies in hospital to prevent contact transmission of methicillin-resistant Staphylococcus aureus

Background

Cleaning of environmental surfaces in hospitals is important for the control of methicillin-resistant Staphylococcus aureus (MRSA) and other hospital-acquired infections transmitted by the contact route. Guidance regarding the best approaches for cleaning, however, is limited.

Methods

In this study, a mathematical model based on ordinary differential equations was constructed to study MRSA concentration dynamics on high-touch and low-touch surfaces, and on the hands and noses of two patients (in two hospitals rooms) and a health care worker in a hypothetical hospital environment. Two cleaning interventions – whole room cleaning and wipe cleaning of touched surfaces – were considered. The performance of the cleaning interventions was indicated by a reduction in MRSA on the nose of a susceptible patient, relative to no intervention.

Results

Whole room cleaning just before first patient care activities of the day was more effective than whole room cleaning at other times, but even with 100% efficiency, whole room cleaning only reduced the number of MRSA transmitted to the susceptible patient by 54%. Frequent wipe cleaning of touched surfaces was shown to be more effective that whole room cleaning because surfaces are rapidly re-contaminated with MRSA after cleaning. Wipe cleaning high-touch surfaces was more effective than wipe cleaning low-touch surfaces for the same frequency of cleaning. For low wipe cleaning frequency (≤3 times per hour), high-touch surfaces should be targeted, but for high wipe cleaning frequency (>3 times per hour), cleaning should target high- and low-touch surfaces in proportion to the surface touch frequency. This study reproduces the observations from a field study of room cleaning, which provides support for the validity of our findings.

Conclusions

Daily whole room cleaning, even with 100% cleaning efficiency, provides limited reduction in the number of MRSA transmitted to susceptible patients via the contact route; and should be supplemented with frequent targeted cleaning of high-touch surfaces, such as by a wipe or cloth containing disinfectant.

Puerperal sepsis and maternal mortality: what role can new technologies play?

OBJECTIVE

To identify new and underutilized technologies to reduce maternal mortality related to puerperal sepsis in developing countries.

METHOD

Review of current medical literature.

RESULT

The literature indicates that infection-control protocols and evidence-based procedures--including prophylactic antibiotics for cesarean section or preterm rupture of membranes, and updated antibiotic regimens--should be widely adopted. Devices such as hand rubs, needle-disposal systems, and rapid microbiological diagnostic tests can improve compliance and efficiency. Operational research on promising developments like vaginal cleansing with antiseptics, vitamin A supplementation, and prophylactic antibiotics in high-risk women is needed.

CONCLUSION

Sepsis management continues to depend on good implementation of established technologies. Program-based approaches are required to improve uptake.

Effectiveness of a multimodal hand hygiene improvement strategy in the emergency department

BACKGROUND

Hand hygiene (HH) is essential in preventing nosocomial infection. The emergency department (ED) is an open portal of entry for pathogens into the hospital system, hence the important sentinel function of the ED personnel. The main objective of this study was to assess the effect of a multimodal improvement strategy on hand hygiene compliance in the ED.

METHODS

Our study was a prospective before-and-after study to determine the effect of a multimodal improvement strategy on the compliance of HH in the ED according to the My 5 Moments of Hand Hygiene defined by the World Health Organization. Interventions such as education, reminders, and regular feedback on HH performance and role models were planned during the 3 intervention weeks.

RESULTS

In total, 57 ED nurses and ED physicians were observed in this study, and approximately 1,000 opportunities for handrubs were evaluated during the 3 intervention periods. HH compliance increased significantly from baseline from 18% (74/407) to 41% (77/190) after the first intervention and stabilized to 50% (99/200) and 46% (96/210) after the second and third interventions, respectively.

CONCLUSIONS

Implementing a multimodal HH improvement program significantly improved the HH compliance of ED personnel.

An assessment of hand hygiene practices of healthcare workers of a semi-urban teaching hospital using the five moments of hand hygiene

Background:

Hand hygiene has been described as the cornerstone and starting point in all infection control programs, with the hands of healthcare staff being the drivers and promoters of infection in critically ill patients. The objectives of this study were to access healthcare workers compliance with the World Health Organization (WHO) prescribed five moments of hand hygiene as it relates to patient care and to determine the various strata of healthcare workers who are in default of such prescribed practices.

Methods:

The study was an observational, cross-sectional one. Hand hygiene compliance was monitored using the hand hygiene observation tool developed by the WHO. A nonidentified observer was used for monitoring compliance with hand hygiene. The observational period was over a 60-day period from August 2015 to October 2015.

Results:

One hundred and seventy-six observations were recorded from healthcare personnel. The highest number of observations were seen in surgery, n = 40. The following were found to be in noncompliance before patient contact – anesthetist P = 0.00 and the Intensive Care Unit P = 0.00 while compliance was seen with senior nurses (certified registered nurse anesthetist [CRNA]) P = 0.04. Concerning hand hygiene after the removal of gloves, the following were areas of noncompliance - the emergency room P = 0.00, CRNA P = 0.00, dental P = 0.04, and compliance was seen with surgery P = 0.01. With regards to compliance after touching the patient, areas of noncompliance were the anesthetists P = 0.00, as opposed to CRNA P = 0.00, dental P = 0.00, and Medicine Department P = 0.02 that were compliant. Overall, the rates of compliance to hand hygiene were low.

Discussion:

The findings however from our study show that the rates of compliance in our local center are still low. The reasons for this could include lack of an educational program on hand hygiene; unfortunately, healthcare workers in developing settings such as ours regard such programs as being mundane.

Conclusion:

The observance of hand hygiene is still low in our local environment. Handwashing practices in our study show that healthcare workers pay attention to hand hygiene when it appears there is a direct observable threat to their wellbeing. Educational programs need to be developed to address the issue of poor hand hygiene.

Effectiveness of an extended period of flashing lights and strategic signage to increase the salience of alcohol-gel dispensers for improving hand hygiene compliance

BACKGROUND

Multiple factors affect compliance with hand hygiene, including conspicuity of alcohol-gel dispensers. Previous studies have shown that flashing lights increase hand hygiene compliance; however, the durability of this effect has not been studied.

METHODS

We affixed flashing lights to hand sanitizer dispensers for a total of 6 weeks. Regression analysis was used to compare compliance rates between the beginning and end of the intervention. Our secondary objective was to determine whether compliance rates in cold weather could be improved by adding a sign separated in time and space from the dispensers.

RESULTS

Flashing lights improved hand hygiene compliance from 11.8% to 20.7%, and this effect was unchanged over the 6-week study period. Fully charged lights resulted in a greater compliance increase. A preemptive sign did not have a significant effect on hand hygiene rates nor did absolute temperatures.

CONCLUSIONS

Flashing lights are a simple, inexpensive way of improving hand hygiene. Brighter lights appear to have a greater effect; however, this must be balanced with annoyance in specific settings. Temperature did not have a significant effect; however, this may be because the relationship does not fit a linear model. Other interventions, such as signs, may need to be tailored specifically to individual hospital environments.

Hand Hygiene Among Laboratory Workers

We performed a study to measure the compliance of laboratory personnel with different components of hand hygiene. The level of compliance at the end of duty was 100%; however, 36.7% of subjects wore a ring, 46.9% wore a watch, and 6.1% wore a bracelet. Pathogenic microorganisms were exclusively found on hands of laboratory personnel who wore jewelry. After interventions, the level of compliance with the no-jewelry policy among laboratory personnel showed sustained improvement. Efforts to improve hand hygiene should be directed not only at healthcare workers but also at laboratory personnel.

The use of passive visual stimuli to enhance compliance with handwashing in a perioperative setting

BACKGROUND

To encourage handwashing, we analyzed the effect that a passive visual stimulus in the form of a picture of a set of eyes had on self-directed hand hygiene among health care staff.

METHODS

This was a prospective, single-blind study using a repeated measure design. Four dispensers of alcohol foam located in positions identified as #1, #2, #3, and #4 were used to deliver a single uniform volume of alcohol foam in an automated fashion. Pictures of eyes were placed on dispensers #1 and #3 but not dispensers #2 and #4 for 1 time period. The visual stimulus was rotated with each study time period. At the end of each study period, the volumes dispensed were examined to determine if the visual stimulus had a statistically significant influence on the volume dispensed.

RESULTS

There were a total of 6 time periods. The average volume dispensed in stations with eyes was 279 cc versus that in the stations without eyes, which was 246 cc, and this was a statistically significant difference (P = .009).

CONCLUSION

The correct visual stimuli may enhance compliance with hand hygiene in health care settings.

Towards an antimicrobial 'microglove'

A large proportion of hospital-related infections are acquired and spread due to the direct contacts between patients and healthcare workers. Accordingly, proper infection prevention measures, and especially hand hygiene, are key to limit the spread of infections in nosocomial settings. However, healthcare workers frequently experience difficulties in complying strictly to hand disinfection protocols. This study was therefore aimed at the development of a hand rub with antimicrobial activity that forms a protective film on the hand, a so-called microglove, in order to enhance hand hygiene. For this purpose, various co-polymer formulations consisting of different ratios of Polyvinylpyrrolidone (PVP) and a branched C20 derivatized maleate (M20) in combination with the known biocide benzalkonium chloride (BKC) were tested for their combined film-forming and antimicrobial activities. The results of a series of novel contamination and transmission assays show that a formulation of 80% PVP and 20% M20 co-polymer with 0.9% BKC fulfils the elementary requirements for an antimicrobial microglove.
