Improving compliance with hand hygiene in hospitals

Assessment of Methicillin-Resistant Staphylococcus aureus (MRSA) knowledge and awareness among healthcare workers in South-Lebanon

Background

Methicillin-Resistant Staphylococcus aureus (MRSA) is a well-known cause of hospital acquired infections (HAIs), associated with high rates of morbidity and mortality. In healthcare settings, MRSA can spread via contaminated surfaces and direct contact.

Objective

This study aims to assess the knowledge and awareness of MRSA risks, prevention methods (such as hand hygiene), proper antibiotics use, and multidrug resistance among various groups of healthcare workers (HCWs) in Southern Lebanon.

Methods

A total of 244 HCWs, including those in medical services (MS), paramedical services (PS), and non-medical services (NMS), were conveniently selected for this study. Data was gathered using a structured, validated questionnaire that explored their knowledge and awareness of MRSA risks, prevention measures, hand hygiene practices, and multidrug resistance.

Results

The findings revealed that 68% of HCWs were aware of the origin of MRSA infection, and 61.5% and 51.6% were familiar with its treatment and transmission, respectively. Only 24.2% of HCWs were able to differentiate between hospital-acquired and community-acquired MRSA, 14.7% were aware of the institution's written MRSA control protocols, and 17.6% had heard of MRSA infections. Notably, knowledge and hand hygiene practices were significantly better among MS HCWs than PS and NMS groups (P<0.0001). While all HCWs were familiar with antibiotic usage and drug resistance, NMS HCWs were more likely to use antibiotics without a prescription compared to MS and PS groups (P<0.003).

Conclusion

HCWs in South-Lebanon demonstrated a knowledge gap regarding MRSA risks and prevention guidelines. These findings underscore the need for targeted educational intervention on MRSA, as well as coordinated efforts by healthcare authorities and centres to control MRSA infections.

A "Wise" Intervention to Increase Hand Hygiene Compliance of Nurses in Acute Care Units in US Hospitals: A Multiple Baseline Interrupted Time-Series Evaluation

This study tested a 'wise' intervention (quick prompt of a specific psychological mec) in acute care hospital units to improve nurses' hand hygiene compliance (HHC). A multiple baseline design in two medical-surgical teaching hospitals in the United States. Hand hygiene data was collected using an electronic compliance monitoring system with sensors placed in doorways and on corresponding soap and alcohol-based hand rub dispensers. The outcome measure was the proportion of opportunities in which HH was undertaken by staff per week in each unit. A quick-and-easy psychological prime to reinvigorate professional identity. Interrupted time series analysis using a quasi-Poisson regression model with statistical process control charts for each unit. A statistically significant increase in HHC rates that was sustained for months post-intervention. However, the patterns by unit were not statistically significant once temporal trends were considered. Other factors, such as the unit type and the use of incentives could have impacted the results. These analyses suggest that the aggregate impact should not be taken as evidence of intervention effectiveness. This study therefore cannot be considered to have provided a strong foundation for use of a 'wise' intervention, despite its relatively small financial, logistical and psychological cost.

Learning hand hygiene from the champions: Investigating key compliance facilitators among healthcare workers through interviews

INTRODUCTION

Good hand hygiene compliance among healthcare workers is crucial for preventing healthcare-associated infections. While an extensive amount of research has focused on barriers to compliance with hand hygiene guidelines, there remains a critical gap in understanding the factors contributing to consistently excellent compliance among some individuals. Thus, the main aim of this study is to learn from these "champions" of hand hygiene and identify facilitating factors that enable and sustain high compliance using the Theoretical Domains Framework (TDF).

METHODS

In this qualitative study, we conducted problem-oriented semi-structured interviews with questions based on the 14 domains of the revised TDF. The N = 25 participants included physicians and nurses from three German hospitals. They were selected based on a reported history of excellent hand hygiene compliance.

RESULTS

All topics discussed by the interviewees could be categorised into the 14 TDF domains. Five TDF domains were particularly prominent: environmental context and resources, behavioural regulation, knowledge, social influences, and skills. The single most important facilitator for good hand hygiene compliance among both physicians and nurses was the construct/code goals (i.e., patient protection and self-protection). Additionally, for physicians, developing hand hygiene as a habit was considered particularly advantageous. Conversely, nurses emphasised that learning correct hand hygiene during their vocational training was especially beneficial for good compliance.

CONCLUSIONS

The results highlight the importance of clear goals, habit development, comprehensive training, adequate resources, and a positive culture of communication in promoting good hand hygiene practices. The TDF has been proven to be a suitable model for identifying facilitating factors for hand hygiene compliance among healthcare workers.

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.

Predictors of hand hygiene attitudes among Saudi healthcare workers of the intensive care unit in Saudi Arabia

Healthcare-associated infections present a challenge to healthcare systems, particularly critical care units. Hand hygiene emerges as a crucial element in infection control, acting as a vital link between healthcare workers, patients, and pathogens. Positive attitudes, motivated by a genuine concern for patient safety, are recognized as major predictors of hand hygiene compliance among healthcare workers. This study aims to assess the attitudes of ICU staff toward hand hygiene and identify factors that influence these attitudes. A cross-sectional survey of intensive care unit staff in seven large Saudi hospitals was conducted using an anonymous, self-reporting questionnaire to examine the attitudes of ICU personnel about hand hygiene and determine the factors that impact these attitudes. A regression analysis was used to determine the determinants of hand hygiene attitudes. Of the 600 respondents, 93% rated their hand hygiene knowledge as good, and 71% received hand hygiene training from their hospital. Most respondents (78%) had previously experienced healthcare-associated infections. The majority reported a favorable overall attitude toward hand hygiene (M = 4.15, SD = 0.85). Attitudes toward hand hygiene were significantly associated with perceived knowledge (β = 0.32, p < 0.001), prior hand hygiene training (β = 0.13, p < 0.05), and years of experience (β = - 0.10, p < 0.05). Healthcare workers in the ICU have a generally positive attitude toward hand hygiene. Such attitudes were correlated with hand hygiene knowledge, prior training, and job experience. The study's findings can help to inform health promotion initiatives and campaigns aimed at achieving long-term improvements in hand hygiene behaviors.

Process Evaluation of an Acute-Care Nurse-Centred Hand Hygiene Intervention in US Hospitals

This paper describes a process evaluation of a 'wise' intervention that took place in six acute care units in two medical-surgical teaching hospitals in the United States during 2016-2017. 'Wise' interventions are short, inexpensive interventions that depend on triggering specific psychological mechanisms to achieve behaviour change. This study sought to increase the hand hygiene compliance (HHC) rates before entering a patient's room among nurses. The intervention centred on the use of threat to professional identity to prompt improved HHC. Through questionnaires administered to intervention participants and the implementation facilitator, together with independent observation of intervention delivery, we examined whether the steps in the Theory of Change occurred as expected. We found that aspects of the implementation-including mode of delivery, use of incentives, and how nurses were recruited and complied with the intervention-affected reach and likely effectiveness. While components of the intervention's mechanisms of impact-such as the element of surprise-were successful, they ultimately did not translate into performance of the target behaviour. Performance was also not affected by use of an implementation intention as repeated performance of HHC over years of being a nurse has likely already established well-ingrained practices. Context did have an effect; the safety culture of the units, the involvement of the Nurse Managers, the level of accountability for HHC in each unit, and the hospitals themselves all influenced levels of engagement. These conclusions should have implications for those interested in the applicability of 'wise' interventions and those seeking to improve HHC in hospitals.

Implementing an Internal Audit: Evaluating Hand Scrub Compliance in a Tertiary Care Hospital

Background Aseptic protocol adherence and sterilization are the most important factors in a patient's satisfactory recovery after surgery. The standard hand scrubbing procedure helps control infection and keeps the surgical site clean by adhering to aseptic principles. Methods Thirty-six young residents and house officers participated in this prospective audit after ethical clearance was obtained. The World Health Organization (WHO) standard criteria were adhered to both before and after the intervention. Participants were observed in the surgical operation theatre (OT) without prior notice to ensure hand hygiene compliance before surgical procedures. The intervention included a video presentation as well as a live demonstration. Results Only 64.41% (n=23) of residents and house officers followed the recommended standard hand hygiene procedures before the intervention. This percentage rose to 93.92% (n=33) following the intervention, suggesting a noteworthy improvement. Conclusion Significant changes in the acceptance rates for the essential requirements of hand hygiene were observed after the evaluation in the second cycle. Adhering to WHO guidelines for procedures will help reduce the risk of infections and promote awareness of asepsis in practice.

Connecting pathogen transmission and healthcare worker cognition: a cognitive task analysis of infection prevention and control practices during simulated patient care

BACKGROUND

Relatively little is known about the cognitive processes of healthcare workers that mediate between performance-shaping factors (eg, workload, time pressure) and adherence to infection prevention and control (IPC) practices. We taxonomised the cognitive work involved in IPC practices and assessed its role in how pathogens spread.

METHODS

Forty-two registered nurses performed patient care tasks in a standardised high-fidelity simulation. Afterwards, participants watched a video of their simulation and described what they were thinking, which we analysed to obtain frequencies of macrocognitive functions (MCFs) in the context of different IPC practices. Performance in the simulation was the frequency at which participants spread harmless surrogates for pathogens (bacteriophages). Using a tertiary split, participants were categorised into a performance group: high, medium or low. To identify associations between the three variables-performance groups, MCFs and IPC practices-we used multiblock discriminant correspondence analysis (MUDICA).

RESULTS

MUDICA extracted two factors discriminating between performance groups. Factor 1 captured differences between high and medium performers. High performers monitored the situation for contamination events and mitigated risks by applying formal and informal rules or managing their uncertainty, particularly for sterile technique and cleaning. Medium performers engaged more in future-oriented cognition, anticipating contamination events and planning their workflow, across many IPC practices. Factor 2 distinguished the low performers from the medium and high performers who mitigated risks with informal rules and sacrificed IPC practices when managing tradeoffs, all in the context of minimising cross-contamination from physical touch.

CONCLUSIONS

To reduce pathogen transmission, new approaches to training IPC (eg, cognitive skills training) and system design are needed. Interventions should help nurses apply their knowledge of IPC fluidly during patient care, prioritising and monitoring situations for risks and deciding how to mitigate risks. Planning IPC into one's workflow is beneficial but may not account for the unpredictability of patient care.

Gender differences in psychosocial determinants of hand hygiene among physicians

OBJECTIVE

We investigated gender differences in psychosocial determinants that affect hand hygiene (HH) performance among physicians.

DESIGN

The survey included a structured questionnaire with 7 parts: self-assessment of HH execution rate; knowledge, attitude, and behavior regarding HH; internal and emotional motivation for better HH; barriers to HH; need for external reminders; preference for alcohol gel; and embarrassment due to supervision.

SETTING

The study was conducted across 4 academic referral hospitals in Korea.

PARTICIPANTS

Physicians who worked at these hospitals were surveyed.

METHODS

The survey questionnaire was sent to 994 physicians of the hospitals in July 2018 via email or paper. Differences in psychosocial determinants of HH among physicians were analyzed by gender using an independent t test or the Fisher exact test.

RESULTS

Of the 994 physicians, 201 (20.2%) responded to the survey. Among them, 129 (63.5%) were men. Male physicians identified 4 barriers as significant: time wasted on HH (P = .034); HH is not a habit (P = .004); often forgetting about HH situations (P = .002); and no disadvantage when I do not perform HH (P = .005). Female physicians identified pain and dryness of the hands as a significant obstacle (P = .010), and they had a higher tendency to feel uncomfortable when a fellow employee performed inadequate HH (P = .098). Among the respondents, 26.6% identified diversifying the types of hand sanitizers as their first choice for overcoming barriers to improving HH, followed by providing reminders (15.6%) and soap and paper towels in each hospital room (13.0%).

CONCLUSION

A significant difference in the barriers to HH existed between male and female physicians. Promoting HH activities could help increase HH compliance.

Level of Physical Activity, Sleep Quality and Use of Personal Protective Equipment of Students at Wroclaw Medical University during the COVID-19 Pandemic

The study was conducted in October 2020 and March 2021 among Wroclaw Medical University students of different years and faculties. The objective of the study was to establish the relationship between some determinants, such as gender and the levels of physical activity, and the quality of sleep of medical students during the pandemic. Ultimately, 696 responses from October and 652 from March were included. To determine the level of physical activity, the International Physical Activity Questionnaire (IPAQ) was used, and for sleep quality, the Pittsburgh Sleep Quality Index (PSQI) was used. The findings pointed to a higher Total MET m/w (metabolic equivalent of task in minutes a week) in men compared to women in both study periods (2020: 1845.8 to 1542.5, p = 0.009; 2021: 2040.7 to 1826.6, p = 0.025). This was mainly due to a higher Vigorous Exercises MET m/w in men (2020: 837.3 to 635.8, p = 0.008; 2021: 773.3 to 490.3, p = 0.0006). Moreover, women had a lower quality of sleep resulting from problems in Habitual Sleep Efficiency, Sleep Disturbances, and Daytime Dysfunctions. An adequate level of physical activity and a good night's rest are the fundaments of health; therefore, it is necessary to determine the causes of their deficiencies in order that we can counteract them.

Improvement of Hand Hygiene Practices among the Healthcare Workers in a Neonatal Intensive Care Unit

BACKGROUND

Healthcare workers' (HCWs) hands become progressively colonized with potential pathogens during their patient care and act as a vehicle for transmission of microorganisms to other patients. Hand hygiene is undisputedly one of the most effective infection control measures. The objective of this study was to measure the hand hygiene (HH) compliance among the doctors and nurses before and after intervention. Methodology. This quasi-experimental (before and after) study was conducted from July 2019 to July 2020 in the neonatal intensive care unit in a tertiary hospital in Bangladesh. The doctors and nurses were observed for their compliance to HH before and after the intervention. Several group discussions were arranged, and posters on HH were attached as reminders at the workstations during the intervention period. Binary logistic regression analysis of the predictors for the outcome as HH noncompliance was performed.

RESULT

The overall compliance to HH was significantly increased in both before (from 42.9 to 83.8%, p=<0.0001) and after (28.5 to 95.9%, p=<0.000) patient contact, in both the case of high-risk and low-risk contacts (p=<0.000) following the intervention. A significant reduction in the frequency of inadequate HH (20.2 to 9.7%, p = .000) was documented. In logistic regression analysis, compliance to HH was found more after the intervention (aOR = 13.315, 95% CI: 7.248-24.458). Similarly, being a physician (aOR = 0.012, 95% CI: 0.005-0.030) and moments after patient contact (aOR = 0.114, 95% CI: 0.049-0.261), significant positive predictors for compliance to HH were found.

CONCLUSION

Significant improvements in HH compliance were achieved through a systemic, multidimensional intervention approach among the doctors and nurses in an intensive newborn care setting.

Knowledge Level on Infection Control among Romanian Undergraduate and Postgraduate Dental Students

Background and Objectives: Infection control practices in dentistry should be continuously evaluated. The aim of the present study was to assess the knowledge of dental students from Iași, Romania about infection control in the dental office. Materials and Methods: Dental students and resident dentists attending the “Grigore T. Popa” University of Medicine and Pharmacy in Iași were randomly selected in accordance with ethical guidelines, and a cross-sectional, questionnaire-based online study was conducted. The questionnaire included 21 items about infection control in dentistry. A descriptive statistical analysis was performed, and the chi-square test was used for data comparison, with a cutoff point of 0.05 for statistical significance. Results: The study sample included 150 subjects (75.3% female and 24.7% male) with a mean age of 25.71 ± 4.54 years. Mode of infection transmission was known by 74% of the subjects, and 76% were aware of standard precautions, with significant differences by the year of study (p = 0.012, r = 0.002). A percentage of 20% of subjects knew the means of transmission of the hepatitis B virus (HBV) (p = 0.032, r = 0.166). Most of the subjects were not vaccinated against HBV (p = 0.002, r = −0.274). Notions of high-level disinfection and sterilization were confused by 19.5% of the subjects. Only 22% of the subjects knew the correct processing of handpieces (p = 0.048, r = −0.071). The sources of information were diverse for 64.66% of the respondents, while 31.33% of them used courses and seminars only. Conclusions: There is a need for improvement in the level of knowledge on infection control for both dental students and residents.

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

Background Over the years, there has been an increase in hospital-acquired infections (HAIs) among patients in India. One of the main reasons is a lack of compliance with infection control guidelines, such as hand hygiene. So the present study was conducted to determine the compliance of hand hygiene among healthcare workers in a private tertiary care teaching hospital in South India. Materials and methods The prospective observational study was carried out between April 2017 and March 2020. Nineteen areas were directly observed for hand hygiene (HH) compliance. At each location, HH audit was conducted for one hour per day for five days per month. HH complete adherence rate (HHCAR) and HH partial adherence rate (HHPAR) were analyzed. Results Nine hundred and twenty observation periods were completed during the entire study period. Overall, hand hygiene complete adherence rate was 29.9% (11,981/39,998); partial adherence rate was 45.3% (18,131/39,998) and the non-adherence rate was 24.7% (9886/39,998). A better adherence rate was seen among nurses (44.7%), followed by other staff (33.7%) and doctors (33.04%). Moment-specific adherence rates show almost equal adherence rates of 50.7%, 50.75%, and 50.1%, respectively, for moments 2, 3, and 4, and comparatively low for moments 1 and 5 (48.4% and 47.6%, respectively). Conclusion Despite adequate hand hygiene facilities, compliance remains low. Hand hygiene is a bundle care approach that needs to consider factors including healthcare staff, clinical, institutional, environmental, and behavioral changes. Multimodal interventions and multidisciplinary commitment are mandatory for sustained compliance.

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.

Cross-Sectional Study to Evaluate Knowledge on Hand Hygiene in a Pandemic Context with SARS-CoV-2

Background and Objectives: The basis of any infection control program is hand hygiene (HH). The aim of this study was to investigate knowledge of HH among medical students. Materials and Methods: Students were randomly selected from two Romanian universities and a cross-sectional, questionnaire-based study was conducted between January and May 2021. The answers regarding demographic data and knowledge concerning the methods, the time and the antiseptics used for HH were collected. The selection of the study group was made according to selection criteria in accordance with ethical issues. A descriptive statistical analysis was performed, and a chi-square test was used for data comparison, with a cut-off point of 0.05 for statistical significance. Results: The results indicated that the attitude of the students towards the practice of HH improved significantly. Most students believe that simple HH can control infections. Significant differences were found by the year of study in terms of the hand surfaces included and recommended duration (p < 0.05). Conclusions: In conclusion, the study shows that most respondents have sufficient knowledge on HH, meaning that a higher compliance is required to control infections. The indicated reasons of non-compliance with HH are emergencies and other priorities.

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

Background:

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

Aim:

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

Methods:

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

Results:

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

Conclusion:

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

Hand Hygiene Evaluation Using Two Different Evaluation Tools and Hand Contamination of Veterinary Healthcare Workers in a Swiss Companion Animal Clinic

Hand hygiene (HH) is the most important measure to prevent nosocomial infections. HH compliance in companion animal clinics has been reported to be poor. The present study compared an online application with the WHO evaluation form to assess the WHO five moments of HH in a Swiss companion animal clinic. In 202 hand swabs from 87 staff members, total viable count (TVC) before and after patient contact was evaluated and the swabs were tested for selected antimicrobial resistant microorganisms of public health importance. HH compliance (95% confidence interval) was 36.6% (33.8–39.5%) and was similar when assessed with the two evaluation tools. HH differed between hospital areas (p = 0.0035) and HH indications (p < 0.0001). Gloves were worn in 22.0% (18.0–26.6%) of HH observations and were indicated in 37.2% (27.3–48.3%) of these observations. Mean TVC before patient contact was lower (0.52 log CFU/cm²) than after patient contact (1.02 log CFU/cm²) but was similar before patient contact on gloved and ungloved hands. Three hand swabs (1.5% (0.4–4.3%)) were positive for methicillin-resistant Staphylococcus aureus. Gloving should not be regarded as a substitute for HH. Overall, HH in companion animal medicine should urgently be fostered.

Skin barrier response to active chlorine hand disinfectant-An experimental study comparing skin barrier response to active chlorine hand disinfectant and alcohol-based hand rub on healthy skin and eczematous skin

BACKGROUND

Alcohol-based hand rub (ABHR) is widely used for hand disinfection in the health care sector. ABHR is, however, known to cause discomfort when applied on damaged skin emphasizing the unmet need for alternative and better tolerated types of disinfectants. Active chlorine hand disinfectants (ACHDs) are potential new candidates; however, the effect on the skin barrier function compared to ABHR remains to be assessed.

MATERIALS AND METHODS

In Study A, the forearm skin of healthy adults was repeatedly exposed to ACHD and ABHR. Skin barrier function was assessed by measurement of transepidermal water loss, electrical conductance, pH, and erythema at baseline and at follow-up after 2 days, and subjective discomfort was likewise assessed. Study B was performed in the same way; however, in order to induce an experimental irritant contact dermatitis, sodium lauryl sulfate patch tests were applied to forearms before exposure to ACHD and ABHR.

RESULTS

In both studies, the skin barrier function was unaffected after repetitive exposure to ACHD and ABHR, and with no significant differences between the products. Subjective discomfort was reported as sporadic or very mild in relation to both products.

CONCLUSION

Our results illustrate that use of ACHD does not affect the skin barrier function negatively, neither in intact skin nor in skin with experimentally induced contact dermatitis. Future studies should include real-life evaluation of skin barrier function and subjective discomfort following ACHD use in individuals with and without hand eczema.

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.

Self-efficacy of health professionals in hand hygiene practice: is it possible to measure?

OBJECTIVE

To identify in the literature the tools used to measure self-efficacy of health professionals in hand hygiene.

METHODS

Integrative literature review carried out by consulting the databases PubMed, Scopus, Web of Science, Cumulative Index to Nursing and Allied Health Literature, Europe PubMed Central, and Science Direct using the descriptors Self Efficacy, Hand Hygiene, and Health Personnel.

RESULTS

Six articles, all of which with observational design, were selected. It was possible to infer that four studies used validated instruments to measure self-efficacy of health professionals in the conformity with the recommendations for hand hygiene. The other studies used questionnaires that were not validated.

FINAL CONSIDERATIONS

Despite the extensive literature on hand hygiene, there is a lack of scientific evidence regarding the use of validated instruments to measure self-efficacy of health professionals in the procedure. The use of properly validated psychometric instruments is useful to guarantee the quality of results in studies.

Light-guided nudging and data-driven performance feedback improve hand hygiene compliance among nurses and doctors

Background

Evidence-based practices to increase hand hygiene compliance (HHC) among health care workers are warranted. We aimed to investigate the effect of a multimodal strategy on HHC.

Methods

During this 14-month prospective, observational study, an automated monitoring system was implemented in a 29-bed surgical ward. Hand hygiene opportunities and alcohol-based hand rubbing events were measured in patient and working rooms (medication, utility, storerooms, toilets). We compared baseline HHC of health care workers across periods with light-guided nudging from sensors on dispensers and data-driven performance feedback (multimodal strategy) using the Student's t test.

Results

The doctors (n = 10) significantly increased their HHC in patient rooms (16% vs 42%, P< .0001) and working rooms (24% vs 78%, P= .0006) when using the multimodal strategy. The nurses (n = 26) also increased their HHC significantly from baseline in both patient rooms (27% vs 43%, P = .0005) and working rooms (39% vs 64%, P< .0001). The nurses (n = 9), who subsequently received individual performance feedback, further increased HHC, compared with the period when they received group performance feedback (patient rooms: 43% vs 55%, P< .0001 and working rooms: 64% vs 80%, P< .0001).

Conclusions

HHC of doctors and nurses can be significantly improved with light-guided nudging and data-driven performance feedback using an automated hand hygiene system.

Standardized aseptic dressing change procedure: Optimizations and adherence in a prospective pre- and postintervention cohort study

BACKGROUND

The "HygArzt" project investigated the effectiveness of hygiene measures introduced by an infection prevention link physician (PLP).

OBJECTIVE

To investigate whether the introduction of a standardized aseptic dressing change concept (ADCC) by a PLP can increase hand hygiene adherence and adherence to specific process steps during an aseptic dressing change (ADC) in a trauma surgery and orthopedic department.

METHODS

We defined 4 required hand disinfection indications: (1) before the preparation of ADC equipment, (2) immediately before the ADC, (3) before the clean phase, and (4) after the ADC. A process analysis of the preintervention phase (331 ADCs) was used to develop a standardized ADCC. The ADCC was introduced and iteratively adopted during the intervention phase. The effect was evaluated during the postintervention phase (374 ADCs).

RESULTS

Hand hygiene adherence was significantly increased by the introduction of the ADCC for all indications: (1) before the preparation of the ADC equipment (from 34% before to 85% after, P <.001), (2) immediately before an ADC (from 32% before to 85% after; P < .001), (3) before the clean phase (from 42% before to 96% after; P < .001), and (4) after an ADC (from 74% before to 99% after; P < .001). Overall hand hygiene adherence was analyzed before the indications for an ADC (from 9.6% before to 74% after; P < .001). The same strategy was applied to the following process parameters: use of a clean work surface, clean withdrawal of equipment from the dressing trolley, and appropriate waste disposal.

CONCLUSIONS

A PLP sufficiently implemented a standardized concept for aseptic dressing change during an iterative improvement process, which resulted in a significant improvement in hand hygiene and adherence to other specific ADCC process steps.

Fear of Hospital-Acquired Infections: The Combined Impact of Patient's Hygiene Sensitivity and Perceived Staff Preventive Behavior

Over the years, the public has paid growing attention to hospital-acquired infections (HAIs). Currently, infection prevention and control are considered a number one national priority in leading developed countries. However, while some hospital visitors are knowledgeable of the topic, others may be ignorant or careless as regards sterility and hygiene-related matters. This study, conducted in Israel, compared people cognizant of hygiene-related issues to those who are less so, in an attempt to account for differences in terms of attitudes and perceptions regarding the hospital environment. Based on Endsley's (in: Proceedings of the IEEE 1988 national aerospace and electronics conference, IEEE, 1988, 1995) situation awareness concept, we hypothesized that people attending the hospital with different hygiene schema would react differently when faced with HAI-related triggers. Based on a survey of 208 respondents, the results support the hypotheses, and showed a significant moderating effect of hygiene-sensitivity on the relationship between the staffs' hospital acquired infection-related proactive behavior and avoidance tendencies among hospital visitors. Theoretical as well as practical recommendations are discussed.

Hand Hygiene Compliance at Critical Points of Care

BACKGROUND

Most articles on hand hygiene report either overall compliance or compliance with specific hand hygiene moments. These moments vary in the level of risk to patients if healthcare workers (HCWs) are noncompliant. We assessed how task type affected HCWs' hand hygiene compliance.

METHODS

We linked consecutive tasks individual HCWs performed during the Strategies to Reduce Transmission of Antimicrobial Resistant Bacteria in Intensive Care Units (STAR*ICU) study into care sequences and identified task pairs-2 consecutive tasks and the intervening hand hygiene opportunity. We defined tasks as critical and/or contaminating. We determined the odds of critical and contaminating tasks occurring, and the odds of hand hygiene compliance using logistic regression for transition with a random effect adjusting for isolation precautions, glove use, HCW type, and compliance at prior opportunities.

RESULTS

Healthcare workers were less likely to do hand hygiene before critical tasks than before other tasks (adjusted odds ratio [aOR], 0.97 [95% confidence interval {CI}, .95-.98]) and more likely to do hand hygiene after contaminating tasks than after other tasks (aOR, 1.12 [95% CI, 1.10-1.13]). Nurses were more likely to perform both critical and contaminating tasks, but nurses' hand hygiene compliance was better than physicians' (aOR, 0.94 [95% CI, .91-.97]) and other HCWs' compliance (aOR, 0.87 [95% CI, .87-.94]).

CONCLUSIONS

Healthcare workers were more likely to do hand hygiene after contaminating tasks than before critical tasks, suggesting that habits and a feeling of disgust may influence hand hygiene compliance. This information could be incorporated into interventions to improve hand hygiene practices, particularly before critical tasks and after contaminating tasks.

How irritant are n-propanol and isopropanol? - A systematic review

BACKGROUND

The use of alcoholic-based hand rubs (ABHRs) is an important tool for hand hygiene, especially in times of the COVID-19 pandemic. Possible irritant effects of ABHR may prevent their use by persons at risk of infection.

METHODS

This systematic review is based on a PubMed search of articles published between January 2000 and September 2019 in English and German, and a manual search, related to the irritation potential of alcohol-based disinfectants restricted to n-propanol (1-propanol) and its structural isomer isopropanol (isopropyl alcohol, 2-propanol).

RESULTS

The majority of the included studies show a low irritation potential of n-propanol alone. However, recent studies provide evidence for significant barrier damage effects of repeated exposure to 60% n-propanol in healthy, as well as atopic skin in vivo. The synergistic response of combined irritants, (ie, a combination of n-propanol or isopropanol with detergents such as sodium lauryl sulfate) is greater, compared with a quantitatively identical application of the same irritant alone.

CONCLUSION

While recent studies indicate a higher risk of skin irritation for n-propanol and isopropanol than reported in the past, this risk still seems to be lower than that for frequent handwashing with detergents, as recommended by some to prevent COVID-19 infections.

Evolution and associated factors of hand hygiene compliance in a pediatric tertiary hospital

BACKGROUND

The objective is to know the evolution of the Degree of Compliance with Recommendations (DCR) on hand hygiene (HH) and its associated factors in the pediatric care areas (PCAs) of a tertiary hospital.

METHODS

Observational, cross-sectional study, repeated over time, with direct observation of the DCR on HH during the daily activity of health care workers. Over 13 years, 9226 HH opportunities were observed. Associations between DCR, PCA and other variables (eg, age, sex, and professional position) were examined using χ² and adjusted odds ratios (aOR) with 95% confidence intervals (CI).

RESULTS

DCR on HH in 9 PCAs was 64.3% (95% CI, 63.3-65.3), and in the group of non-pediatric areas it was 49.6% (95% CI, 49.1-50.1). The areas with the highest degree of compliance were Oncology 72.8% (95% CI, 69.2-76.4), Neonatology 73.2% (95% CI, 71.3-75.1), and Neonatal intensive care unit 70.0% (95% CI, 67.5-72.6). These were the areas with the strongest association with HH compliance, with aOR:2.8 (95% CI, 2.2-3.6); aOR, 3.0 (95% CI, 2.6-3.6) aOR:2.6 (95% CI, 2.1-3.1), respectively. Other associated factors were the indications "after an activity," aOR, 1.6 (95% CI, 1.5-1.8) and the availability of pocket-size alcohol-based solution, aOR, 2.1(95% CI, 1.9-2.3).

CONCLUSIONS

The DCR on HH in PCAs is higher than in other areas, although there is still margin for improvement. We have identified modifiable factors that have an independent association with HH compliance in PCAs. Focusing on modifiable factors will increase compliance with HH with the ultimate goal of reducing healthcare associated infections.

Hand hygiene compliance among healthcare workers in Ghana’s health care institutions: An observational study

Objective

To assess hand hygiene compliance in selected primary hospitals in Ghana.

Design

A cross-sectional health facility-based observational study was conducted in primary health care facilities in five regions in Ghana. A total of 546 healthcare workers including doctors, nurses, midwives and laboratory personnel from 106 health facilities participated in the study.

Main outcome measures

The main outcome measures included availability of hand hygiene materials and alcohol job aids; compliance with moments of hand hygiene; and compliance with steps in hygienic hand washing. These were assessed using descriptive statistics.

Results

The mean availability of hand hygiene material and alcohol job aids was 75% and 71% respectively. This was described as moderately high, but less desirable. The mean hand hygiene compliance with moments of hand hygiene was 51%, which was also described asmoderately high, but less desirable. It was observed that, generally, hand hygiene was performed after procedures than before. However, the mean compliance with steps in hygienic hand washing was 86%, which was described as high and desirable.

Conclusion

Healthcare workers are generally competent in performance of hygienic hand washing. However, this does not seem to influence compliance with moments of hand hygiene. Efforts must therefore be made to translate the competence of healthcare workers in hygienic hand washing into willingness to comply with moments of hand hygiene, especially contact with patients.

Impact of an automated hand hygiene monitoring system combined with a performance improvement intervention on hospital-acquired infections

OBJECTIVE

Hand hygiene adherence has been associated with reductions in nosocomial infection. We assessed the effect of improvements in electronically measured hand hygiene adherence on the incidence of hospital-acquired infections.

METHODS

This quasi-experimental study was conducted in a 555-bed urban safety-net level I trauma center. The preintervention period was January 2015 through June 2016. Baseline electronic hand hygiene data collection took place from April through June 2016. The intervention period was July 2016 through December 2017. An electronic hand hygiene system was installed in 4 locations in our hospital. Performance improvement strategies were implemented that included education, troubleshooting, data dissemination, and feedback. Adherence rates were tracked over time. Rates of hospital-acquired infections were evaluated in the intervention units and in control units selected for comparison. The intervention period was subdivided into the initial and subsequent 9-month periods and were compared to the baseline period.

RESULTS

Electronically measured hand hygiene rates improved significantly from baseline to intervention, from 47% 77% adherence. Rates >70% continued to be measured 18 months after the intervention. Interrupted time series analysis indicated a significant effect of hand hygiene on healthcare facility-onset Clostridioides difficile infection rates during the first 9 months of the intervention. This trend continued during the final 9 months of the intervention but was nonsignificant. No effects were observed for other hospital-acquired infection rates.

CONCLUSIONS

Implementation of electronic hand hygiene monitoring and performance improvement interventions resulted in reductions in hospital-onset Clostridioides difficile infection rates.

Comparison of knowledge, attitudes and hand hygiene behavioral intention in medical and nursing students

Introduction

Hand hygiene is crucial to prevent cross infection. Healthcare students are in a prime position to learn hand hygiene skills. The aim of this study was to analyze hand hygiene behavioral intentions of healthcare students before and after contact with the patient and to compare the knowledge of and attitude towards hand hygiene between medical and nursing students.

Methods

In a descriptive survey research design, convenience selection of a sample of medical students (n=657) and nursing students (n=303) was done from modules taught by the Department of Preventive Medicine and Public Health in both Medicine and Nursing undergraduate degrees in four Spanish universities. The hand hygiene Questionnaire, a validated instrument to evaluate behavior, knowledge, and attitudes, was used.

Results

A significantly lower percentage of students reported always or almost always carrying out hand hygiene before contact with the patient or invasive procedures in comparison to the percentage complying after contact with secretions or with the patient. Although hand hygiene knowledge appears acceptable, its importance is not sufficiently valued.

Conclusions

There are deficiencies in behavioral intention, knowledge, and attitudes related to hand hygiene in medical and nursing students. Better results are observed among nursing students, especially those who have received specific training.

Assessment of correlates of hand hygiene compliance among final year medical students: a cross-sectional study in the Netherlands

OBJECTIVES

To identify the factors that influence the hand hygiene compliance of final year medical students, using a theoretical behavioural framework.

DESIGN

Cross-sectional survey assessing self-reported compliance and its behavioural correlates.

SETTING

Internships of medical students in the Netherlands.

PARTICIPANTS

322 medical students of the Erasmus Medical Center were recruited over a period of 12 months during the Public Health internship, which is the final compulsory internship after an 18-month rotation schedule in all major specialities.

PRIMARY AND SECONDARY OUTCOME MEASURES

Behavioural factors influencing compliance to hand hygiene guidelines were measured by means of a questionnaire based on the Theory of Planned Behaviour and Social Ecological Models. Multiple linear regression analysis was used to identify the effect of including attitudes, social norms, self-efficacy, knowledge, risk perception and habit on hand hygiene compliance.

RESULTS

We included 313 students in the analysis (response rate 97%). The behavioural model explained 40% of the variance in self-reported compliance (adjusted R²=0.40). Hand hygiene compliance was strongly influenced by attitudes (perceived outcomes of preventive actions), self-efficacy (perception of the ability to perform hand hygiene at the clinical ward) and habit, but was not associated with knowledge and risk perception.

CONCLUSIONS

Targeting medical students' behaviour should focus on the empowerment of these juniors and provide them with evidence on the health benefits of prevention, rather than increasing their factual knowledge of procedures. Clinical teaching environments could help them form good patient safety habits during this vital phase of their career.

Survey of isolation room equipment and resources in an academic hospital

PURPOSE

The purpose of this paper, a point prevalence study, is to quantify the incidence of isolation and identify the type of communicable diseases in isolation. The paper evaluates isolation precaution communication, availability of personal protective equipment (PPE) as well as other equipment necessary for maintaining isolation precautions.

DESIGN/METHODOLOGY/APPROACH

A standardised audit tool was developed in accordance with the National Standards for the Prevention and Control of Healthcare Associated Infections (May 2009). Data were collected from 14 March 2017 to 16 March 2017, through observation of occupied isolation rooms in an academic hospital in Dublin, Ireland. The data were subsequently used for additional analysis and discussion.

FINDINGS

In total, 14 per cent (125/869) of the total inpatient population was isolated at the time of the study. The most common isolation precaution was contact precautions (96.0 per cent). In all, 88 per cent of known contact precautions were due to multi-drug resistant organisms. Furthermore, 96 per cent of patients requiring isolation were isolated, 92.0 per cent of rooms had signage, 90.8 per cent had appropriate signs and 93.0 per cent of rooms had PPE available. Finally, 31 per cent of rooms had patient-dedicated and single-use equipment and 2.4 per cent had alcohol wipes available.

PRACTICAL IMPLICATIONS

The audit tool can be used to identify key areas of noncompliance associated with isolation and inform continuous improvement and education.

ORIGINALITY/VALUE

Currently, the rate of isolation is unknown in Ireland and standard guidelines are not established for the evaluation of isolation rooms. This audit tool can be used as an assessment for isolation room compliance.

Healthcare-associated infections and compliance of hand hygiene among healthcare workers in a tertiary health facility, southwest Nigeria

Introduction

Healthcare-associated infections (HAIs) are threats in healthcare settings contributing to increased morbidity, mortality and antimicrobial resistance worldwide. Hand hygiene (HH) is the simplest and most important single intervention to reduce HAIs.

Aims/objectives

This study sought to determine rates of HAIs as well as compliance of HH among healthcare workers (HCWs) in Obafemi Awolowo University Teaching Hospitals Complex (OAUTHC).

Methods

A cross-sectional study was conducted among 227 HCWs (59 doctors, 129 nurses and 39 ward attendants) selected by multistage sampling across 10 hospital wards. Electronic interviewer-administered questionnaire, HH compliance checklist and point prevalence of HAI were done using World Health Organization and Centers for Disease Control and Prevention toolkits, respectively.

Results

Only 20.33% (n = 12) of doctors, 3.88% (n = 5) of nurses and 2.56% (n = 1) of ward attendants had good knowledge of HH (χ² = 22.22, P value = 0.01). Among doctors, 11.86% (n = 7), 6.98% (n = 9) of nurses and 2.56% (n = 1) of ward attendants had positive perception towards HH (χ² = 7.87, P value = 0.25). Of the 174 opportunities for HH observed, compliance rates were 42.37%, 55.81% and 68.97% among doctors, nurses and ward attendants, respectively. Point prevalence of HAI was 16.38%.

Discussion

Good knowledge and positive perception about HH were uncommon among doctors, nurses and ward attendants. However, ward attendants had the highest compliance to HH. There was a high prevalence of HAIs in this institution.

Practice Makes Empowered: Cultivating Elderly Patients' Voices to Protect Their Health through an Interactive Training

Hospital-acquired infections (HAIs) result in approximately 75,000 deaths each year. Elderly patients are particularly susceptible to contracting HAIs. Physicians can reduce the spread of HAIs by washing their hands; however, handwashing compliance remains suboptimal. The Centers for Disease Control and Prevention (CDC) urges patients to remind their physicians to wash their hands; however, older patients are reluctant to make this request. Thus, the purpose of this study was to empower elderly patients to ask their physicians to wash their hands through a series of training videos. We conducted focus groups with elderly patients (N = 82) to uncover their specific barriers to making the request and addressed their concerns in a video training that allowed them to practice making the request. In-depth interviews (N = 19) revealed that elderly patients felt confident to make the request after completing the training. Empowering elderly patients can reduce the spread of deadly HAIs and encourage older people to voice their concerns.

Hand antisepsis without decreasing efficacy by shortening the rub-in time of alcohol-based handrubs to 15 seconds

BACKGROUND

A previous study among neonatal intensive care unit (NICU) nurses showed that the antibacterial efficacy of alcohol-based handrubs (ABHR) can be achieved in 15 s instead of 30 s with a significant increase in the frequency of hand antisepsis. This study aimed to examine 15-s vs 30-s antisepsis performance by measuring microbial load on fingertips and compliance among nurses in a low-risk gynaecological ward.

METHODS

An independent trained observer monitored the frequency and compliance with hand antisepsis during shifts in a crossover design. Fingertips including thumbs were rinsed in soy broth before hand rubbing at the beginning of a shift and then hourly to determine the bacterial load. Performance activity was assigned to the contamination class of the Fulkerson scale. Immediately before the lunch break, volunteers cleaned their hands for a randomly determined application time of 15 or 30 s.

RESULTS

Examination of bacterial load on fingertips revealed no difference between 15 vs 30 s application time. Controlled hand antisepsis before the lunch break also showed no difference in efficacy for either test series. Participants rubbing for 15 s were more likely to perform hand antisepsis compared with those rubbing for 30 s (P=0.2). The compliance increased from 54.7% to 69.5% in the 15-s trial.

DISCUSSION

Shortening the duration for hand antisepsis did not decrease efficacy. Shortening the application time to 15 s should be considered within the critical components of a successful multimodal intervention strategy to improve hand-hygiene compliance in clinical practice.

Evaluating the effectiveness of the "Germ-Free Hands" intervention for improving the hand hygiene practices of public health students

PURPOSE

This quasi-experimental study sought to assess the effectiveness of a multidisciplinary intervention called "Germ-Free Hands" to improve the hand hygiene practices of students attending Thailand's Sirindhorn College of Public Health (SCPH).

METHODS

The intervention was developed and implemented at SCPH and incorporated education, training, a workshop, and performance feedback. The intervention targeted behavioral antecedents specified by the Health Belief Model (HBM) and the Theory of Planned Behavior (TPB). Handwashing determinants (knowledge, beliefs, attitudes, subjective norms, perceived behavioral control, and intentions) and hand hygiene behaviors were assessed at baseline, immediately post-intervention, and 3 months post-intervention for the intervention group at (n=60) at the Suphanburi campus of SCPH and a matched control group (n=60) of students at the Ubonratchathani campus. Data analysis included descriptive statistics, independent samples t-tests, two-way measures of analysis of variance, and a generalized estimating equation to compare handwashing practices by self-reports between two groups.

RESULTS

The "Germ-Free Hands" intervention produced significant improvements in the intervention group's handwashing knowledge, behavioral and control beliefs, subjective norm scores, intentions, and behaviors, as compared to the control group. However, the intervention had no significant impact on normative beliefs, attitudes, or perceived behavioral control. Reported improvements also decreased 3 months post-intervention, and the number of bacterial colonies on students' hands increased over the course of the study.

CONCLUSION

This study adds to the evidence that multidisciplinary interventions can be effective at improving handwashing rates. However, education and training must be continuous, rather than delivered as a one-time program, in order to have sustained results. Participants may also require more in-depth instruction in correct handwashing and drying techniques to remove bacteria effectively and prevent recolonization.

Barriers to hand hygiene practices among health care workers in sub-Saharan African countries: A narrative review

BACKGROUND

Hand hygiene (HH) is the primary measure in the prevention of health care-associated infections; however, from published studies, compliance of health care workers (HCWs) to HH guidelines is low. There is currently no review on HH compliance rates in developing countries, specifically sub-Saharan Africa (SSA), or the barriers to compliance. We therefore, through a narrative review, sought to identify the compliance with and the barriers to HH in SSA.

METHODS

From 3 databases, we performed a search of peer-reviewed studies from SSA, conducted among HCWs, published in the English language between 2005 and 2017. Only studies that reported HH compliance and/or barriers were included.

RESULTS

A total of 278 articles were identified, and the final sample of 27 articles was analyzed in full length. Overall, the HH compliance rate was estimated to be 21.1%, and doctors had better compliance irrespective of the type of patient contact. The main barriers identified were heavy workload, infrastructural deficit (eg, lack of water, soap, hand sanitizers, and blocked/leaking sinks), and poorly positioned facilities.

CONCLUSIONS

HH compliance is poor among SSA HCWs. There is a need for more reports of HH compliance in SSA, and emphasis needs to be placed on surgical wards in which surgical site infections-the most common form of health care-associated infections in SSA-are most likely to occur. Barriers identified in this review are consistent with the findings of studies conducted elsewhere; however, it appears that heavy workload, infrastructural deficit, and poorly positioned facilities are more likely in developing countries.

The effect of incorporating covert observation into established overt observation-based hand hygiene promotion programs

BACKGROUND

Covert observation (CO) is reliable for measuring hand hygiene compliance (HHC). However, the benefit of adding CO to overt observation (OO) is uncertain. We evaluated whether incorporating CO into an OO-based hand hygiene (HH) promotion program improves HH rate.

METHODS

Health care worker's HH activities were observed through 5 monitoring sessions (2 in phases 1 and 2 and 1 in phase 3) of simultaneous CO and OO. An intervention was applied-barrier identification interview-only in phase 2.

RESULTS

Overall HHC was 91.0% for OO, and 49.3% for CO. HHC in phase 1 was not changed by repeated CO (34.7% and 34.0%, P = .70). HHC based on CO increased to 66.9% in phase 2 after the application of an intervention (P < .01), but decreased to 57.5% in phase 3 (P < .01). HHC based on OO increased significantly between only the first and second sessions in phase 2 (90.8% and 94.5%, respectively, P = .01).

DISCUSSION

Although CO did not significantly change behavior, HHC with CO responded promptly to the application and cessation of a new intervention.

CONCLUSIONS

CO reflects HHC change more reliably than does OO. However, it is uncertain whether CO will improve HHC.

A multimodal regional intervention strategy framed as friendly competition to improve hand hygiene compliance

OBJECTIVE

To investigate the effects of friendly competition on hand hygiene compliance as part of a multimodal intervention program.

DESIGN

Prospective observational study in which the primary outcome was hand hygiene compliance. Differences were analyzed using the Pearson χ2 test. Odds ratios (ORs) with 95% confidence interval were calculated using multilevel logistic regression.

SETTING

Observations were performed in 9 public hospitals and 1 rehabilitation center in Rotterdam, Netherlands.ParticipantsFrom 2014 to 2016, at 5 time points (at 6-month intervals) in 120 hospital wards, 20,286 hand hygiene opportunities were observed among physicians, nurses, and other healthcare workers (HCWs).InterventionThe multimodal, friendly competition intervention consisted of mandatory interventions: monitoring and feedback of hand hygiene compliance and optional interventions (ie, e-learning, kick-off workshop, observer training, and team training). Hand hygiene opportunities, as formulated by the World Health Organization (WHO), were unobtrusively observed at 5 time points by trained observers. Compliance data were presented to the healthcare organizations as a ranking.

RESULTS

The overall mean hand hygiene compliance at time point 1 was 42.9% (95% confidence interval [CI], 41.4-44.4), which increased to 51.4% (95% CI, 49.8-53.0) at time point 5 (P<.001). Nurses showed a significant improvement between time points 1 and 5 (P<.001), whereas the compliance of physicians and other HCWs remained unchanged. In the multilevel logistic regressions, time points, type of ward, and type of HCW showed a significant association with compliance.

CONCLUSION

Between the start and the end of the multimodal intervention program in a friendly competition setting, overall hand hygiene compliance increased significantly.

Hand Washing Before and After Applying Different Hand Hygiene Techniques in Places of Public Concern in Tripoli-Libya

Background:

Hand hygiene has being considered as one of the primary measures to improve standards and practice for hospital care and to minimize the transmission of nosocomial pathogens. There is substantial evidence that incidence of hospital acquired infections is reduced by applying hand antisepsis. Regarding hand hygiene and public concern, hand washing has revealed that 85% of the observed adults wash their hands after using public toilets.

Objective:

To compare the efficacy of hand rubbing with an alcohol based solution versus conventional hand washing with antiseptic and non-antiseptic soaps in reducing bacterial counts using different hand hygiene techniques.

Methods:

Ninety-three volunteers took part in this study; 57 from Tripoli Medical Center (TMC); 16 from school; 11 from bank; and 9 from office. All volunteers performed six hand hygiene techniques, immediately before and after a volunteer practice activity: hand washing with non-antiseptic soap for 10 and 30 second (s); hand washing with antiseptic soap for 10, 30 or 60 s; and alcohol-based hand rub. A total of 864 specimens were taken: 432 before and 432 after volunteer's hand hygiene. The fingertips of the dominant hand for each volunteer were pressed on to agar for culture before and after each hand hygiene technique. Plates were incubated at 37oC, and colony-forming units were counted after 48 hours and pathogenic bacteria were identified.

Results:

Results showed that 617 specimens (71.41%) were positive for bacterial growth. 301 (48.78%) were from TMC, 118 (19.12%) were from office; 107 (14.34%) were from school and 91 (14.75%) were from bank.

Conclusion:

Both antiseptic and non–antiseptic soaps did not work properly in reducing bacterial counts of worker’s hands at all places of study, but significantly improved by an application of alcohol based gel.

Hand hygiene in hospitals: an observational study in hospitals from two southern states of India

BACKGROUND

Hand hygiene is a simple and low-cost measure to reduce healthcare associated infection yet it has always been a concern in low as well as high resource settings across the globe. Poor hand hygiene during intra-partum and newborn care may result in sepsis, which is a major cause of death among newborns and puts a financial burden on already strained health systems.

METHODS

We conducted non-participatory observations in newborn care units and labour rooms from secondary and tertiary level, public and private hospitals, as part of a baseline evaluation of a quality improvement collaborative across two southern states of India. We assessed hand hygiene compliance during examinations and common procedures, using tools adapted from internationally recommended checklists and World Health Organization's concept of five moments of hand hygiene. We assessed differences in compliance by type (public/private), level (secondary/tertiary) and case load (low/intermediate/high). Analysis was adjusted for clustering and weighted as appropriate.

RESULTS

We included 49 newborn care units (19 private, 30 public) and 35 labour rooms (5 private, 30 public) that granted permission. We observed 3661 contacts with newborns and their environment, 242 per-vaginal examinations and 235 deliveries. For the newborns, a greater proportion of contacts in private newborn units than public complied with all steps of hand hygiene (44% vs 12%, p < 0.001), and similarly in tertiary than secondary units (33% vs 12%, p < 0.001) but there was no evidence of a difference by case load of the facility (low load-28%; intermediate load-14%; high load- 24%, p = 0.246). The component with lowest compliance was glove usage where indicated (20%). For deliveries, hand hygiene compliance before delivery was universal in private facilities but seen in only about one-quarter of observations in public facilities (100% vs 27%, p = 0.012). Average overall compliance for hand-hygiene during per-vaginal examinations was 35% and we found no evidence of differences by type of facility.

CONCLUSION

Observed compliance with hand hygiene was low overall, although better in private than public facilities in both newborn units and labour rooms. Glove usage was a particular problem in newborn care units.

TRIAL REGISTRATION

Retrospectively registered with Clinical Trials Registry- India ( CTRI/2018/04/013014 ).

A comparative study of hand hygiene and alcohol-based hand rub use among Irish nursing and medical students

BACKGROUND

In Ireland, the setting for this study, the national prevalence rate of health care-associated infection (HCAI) in acute-care facilities is 5.2%. Hand hygiene and in particular hand rubbing using alcohol-based hand rub (ABHR) is highly efficacious in preventing HCAI transmission. Yet, compliance among healthcare professionals is sub-optimal. Less is known about the practices of nursing and medical students and no study comparing practices among these groups in Ireland was found. Hence, the aim of this study was to provide insight into the current hand hygiene and hand rubbing practices of nursing and medical students in Ireland and, by doing so, contribute to the broader understanding of this topic.

METHODS

This observational study employed a cross-sectional, self-reported design. An electronically administered questionnaire was sent to all nursing and medical students from one university. Data were analysed using appropriate software.

RESULTS

The response rate was 37% (323/872). Higher compliance with the World Health Organisation 'my five moments for hand hygiene' model was reported among nursing students (NS) than medical students (MS), with scope for improvement in both disciplines identified. Hand hygiene compliance was highest after body fluid exposure (99.5% NS, 91% MS) and lowest after touching a patient's surroundings (61.5% NS, 57.5% MS). Attitudes towards hand rubbing were largely positive in both disciplines. 16% of NS were not aware of the clinical contraindications to ABHR use, compared to 45% of MS. 9% of NS did not know when to use soap and water and when to use ABHR, compared to 36% of MS. In contrast, more medical students (46%) than nursing students (22%) were routinely using alcohol-based hand rub for decontamination of hands as recommended.

CONCLUSIONS

Results suggest scope to review current hand hygiene curricula focusing on the knowledge gaps, the practice deficits and the barriers to ABHR usage identified.

A Novel In Situ Simulation Intervention Used to Mitigate an Outbreak of Methicillin-Resistant Staphylococcus aureus in a Neonatal Intensive Care Unit

OBJECTIVE

To describe the successful implementation of an in situ simulation program to diagnose and correct latent safety threats in a level 4 neonatal intensive care unit (NICU) to mitigate a methicillin-resistant Staphylococcus aureus (MRSA) outbreak.

STUDY DESIGN

An investigational report describes a simulation intervention that occurred during a 4-month MRSA outbreak in a single-center, 46-bed, newly renovated level 4 NICU. The simulation program was developed for all NICU providers in which they were exposed to a 30-minute in situ human simulation intervention that included education, evaluation, and debriefing to resolve perceived or observed latent safety threats. The primary study outcome was improved hand hygiene compliance and an enhanced estimate of the culture of safety during a 6-month period.

RESULTS

A total of 99 healthcare providers including physicians, nurses, respiratory therapists, and environmental service workers completed the course. Before the simulation intervention, there were 18 patients colonized or infected with a single MRSA clone; after the intervention, there were no new episodes of colonization or infection.

CONCLUSIONS

An in situ, simulation-based intervention can counter threats to patient safety related to workflow and lapses in infection control practices and improve patient outcomes.

Human factors considerations in designing for infection prevention and control in neonatal care - findings from a pre-design inquiry

Qualitative data collection methods drawn from the early stages of human-centred design frameworks combined with thematic analysis were used to develop an understanding of infection prevention practice within an existing neonatal intensive care unit. Findings were used to generate a framework of understanding which in turn helped inform a baseline approach for future research and design development. The study revealed that a lack of clarity between infection transmission zones and a lack of design attributes needed to uphold infection prevention measures may be undermining healthcare workers' understanding and application of good practice. The issue may be further complicated by well-intentioned behavioural attitudes to meeting work objectives; undue influences from spatial constraints; the influence of inadvertent and excessive touch-based interactions; physical and/or cognitive exertion to maintain transmission barriers; and the impact of expanding job design and increased workload to supplement for lack of effective barriers. Practitioner Summary: Despite high hand hygiene compliance within a neonatal intensive care unit, healthcare workers expressed concerns about the unit design and infection prevention practice. Early inquiry methods from human-centred design and thematic analysis helped develop a framework to understand how design can be used to aid infection prevention.

Hand hygiene: Attitudes and practices of nurses, a comparison between 2007 and 2015

BACKGROUND

Hand hygiene reduces health care-associated infections significantly. However, international evidence suggests that practices are suboptimal. The objective of this study was to compare and contrast hand hygiene attitudes and practices and alcohol-based handrub (ABHR) use among nurses between 2007 and 2015.

METHODS

In 2007, a random sample of nurses in a large teaching hospital was invited to complete a postal survey using a validated questionnaire. In 2015, the study was replicated among all nurses employed in a university hospital group, including the setting of the original study. Data were analyzed quantitatively and qualitatively using appropriate software.

RESULTS

Attitudes to hand hygiene were positive and >90% of respondents' self-reported compliance before and after patient contact. However, 13% fewer in 2015 (42%) reported using ABHR >90% of the time compared with in 2007 (55%). Of nurses with <2 years' experience, 90% reported using ABHR >50% of the time compared with 73% of nurses with 2-5 years' experience. Barriers to ABHR improved, but remained high (skin sensitivity: 2007: 23%, 2015: 17%; skin damage: 2007: 18%, 2015: 13%; poor user acceptability and tolerance: 2007 and 2015: 25%).

CONCLUSIONS

Use of positive role models, the adoption of a positive social and cultural norm within the organization, and the provision of continuing professional development opportunities may prove useful strategies in harnessing good practice among graduate nurses and in preventing negative socialization from occurring.

Impact of single room design on the spread of multi-drug resistant bacteria in an intensive care unit

Background

Cross-transmission of nosocomial pathogens occurs frequently in intensive care units (ICU). The aim of this study was to investigate whether the introduction of a single room policy resulted in a decrease in transmission of multidrug-resistant (MDR) bacteria in an ICU.

Methods

We performed a retrospective study covering two periods: between January 2002 and April 2009 (old-ICU) and between May 2009 and March 2013 (new-ICU, single-room). These periods were compared with respect to the occurrence of representative MDR Gram-negative bacteria. Routine microbiological screening, was performed on all patients on admission to the ICU and then twice a week. Multi-drug resistance was defined according to a national guideline. The first isolates per patient that met the MDR-criteria, detected during the ICU admission were included in the analysis. To investigate the clonality, isolates were genotyped by DiversiLab (bioMérieux, France) or Amplified Fragment Length Polymorphism (AFLP). To guarantee the comparability of the two periods, the ‘before’ and ‘after’ periods were chosen such that they were approximately identical with respect to the following factors: number of admissions, number of beds, bed occupancy rate, per year and month.

Results

Despite infection prevention efforts, high prevalence of MRD bacteria continue to occur in the original facility. A marked and sustained decrease in the prevalence of MDR-GN bacteria was observed after the migration to the new ICU, while there appear to be no significant changes in the other variables including bed occupancy and numbers of patient admissions.

Conclusion

Single room ICU design contributes significantly to the reduction of cross transmission of MRD-bacteria.

Shortening the Application Time of Alcohol-Based Hand Rubs to 15 Seconds May Improve the Frequency of Hand Antisepsis Actions in a Neonatal Intensive Care Unit

BACKGROUND For alcohol-based hand rubs, the currently recommended application time of 30 seconds is longer than the actual time spent in clinical practice. We investigated whether a shorter application time of 15 seconds is microbiologically safe in neonatal intensive care and may positively influence compliance with the frequency of hand antisepsis actions. METHODS We conducted in vitro experiments to determine the antimicrobial efficacy of hand rubs within 15 seconds, followed by clinical observations to assess the effect of a shortened hand antisepsis procedure under clinical conditions in a neonatal intensive care unit (NICU). An independent observer monitored the frequency of hand antisepsis actions during shifts. RESULTS All tested hand rubs fulfilled the requirement of equal or even significantly higher efficacy within 15 seconds when compared to a reference alcohol propan-2-ol 60% (v/v) within 30 seconds. Microbiologically, reducing the application time to 15 seconds had a similar effect when compared to 30-second hand rubbing, but it resulted in significantly increased frequency of hand antisepsis actions (7.9±4.3 per hour vs 5.8±2.9 per hour; P=.05). CONCLUSION Time pressure and workload are recognized barriers to compliance. Therefore, reducing the recommended time for hand antisepsis actions, using tested and well-evaluated hand rub formulations, may improve hand hygiene compliance in clinical practice.
