Sociocognitive factors determining compliance with standard precautions by nursing professionals during the COVID-19 pandemic

OBJECTIVES

to assess the socio-cognitive factors determining adherence to standard precautions by nursing professionals in care practice during the COVID-19 pandemic in Brazil.

METHODS

an analytical cross-sectional study, carried out with 9,039 nursing professionals in Brazil, using an electronic form containing participant sociodemographic, training and work variables, and the Brazilian version of the Standard Precautions Questionnaire. Descriptive and inferential statistics were used using the statistical software R.

RESULTS

participants recognize standard precautions as effective measures to reduce infections and report intention to perform them. Training regarding standard precautions was evidenced as a facilitator of adherence (4.72; SD: 0.73), and problems related to materials (3.78; SD: 1.45) were a hindrance.

CONCLUSIONS

among the determining factors, facilitating organization presented the highest score, followed by intention to perform. Facilitating and hindering factor identification makes it possible to develop intervention strategies to strengthen patient safety and reduce occupational risks among professionals.

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.

Associations of Socio-Demographic Characteristics of Dairy Goat Farmers in Greece with Biosecurity-Related Practices in the Farms

Given the significance of goat farming in Greece, our study aimed to explore biosecurity conditions on goat farms and refers to an investigation performed on 119 farms countrywide in Greece. The objective of the present work was to evaluate and report on potential associations between the socio-demographic characteristics of goat farmers and practices that play a role in biosecurity on farms. Data were obtained during a large cross-sectional study performed across Greece in 119 goat herds. The socio-demographic characteristics of farmers, as well as 16 variables related to biosecurity, were recorded; these were practices or events that could potentially enhance or compromise biosecurity on farms. A score based on all the biosecurity-related variables was devised by assigning a '1' or '-1' mark for each variable recorded on a farm that could enhance or compromise, respectively, biosecurity. Among variables potentially enhancing biosecurity on farms, the application of disinfections on the farm and the maintenance of isolation for sick animals were practiced more frequently; among variables potentially compromising biosecurity on farms, the presence of hunters in the area around the farm and grazing practices for animals were recorded more frequently. The median overall score for biosecurity-related practices for all farms in the study was 1 (interquartile range: 2.5; minimum: -4; maximum: 5). Among socio-demographic characteristics, the presence of working staff on a farm was associated with five individual biosecurity-related practices and the length of farming experience with three individual biosecurity-related practices. In the multivariable analysis, female farmers (p = 0.007) and the presence of working staff on the farm (p = 0.025) emerged as the two significant socio-demographic characteristics with an association with the overall biosecurity level on farms. This knowledge can be useful when developing biosecurity programs on goat farms. Recognition of locally applied farm-level practices enhancing biosecurity could form a basis for farmers to apply more rigorous and effective relevant plans.

Exploring determinants of hand hygiene among nursing students: A theory of planned behavior approach

BACKGROUND

This study aims to assess the hand hygiene behavior of nursing students and identify the factors influencing this behavior through the "Scale for Assessment Hand Washing Behavior in the Frame of Theory of Planned Behaviour (SAHBTPB)".

METHODS

This descriptive and cross-sectional study was undertaken at the nursing departments of the university's faculty of health sciences in İzmir, Turkey between 2021 and 2022. A total of 240 nursing students were recruited as participants for this study. Data were collected with the SAHBTPB. The data was analyzed using descriptive statistics, the Chi-square test, and correlation analysis in the SPSS 21.0 program (p < .05).

RESULTS

Participation rate was 74.76%. The mean age of the students was 20.59 ± 1.59 years and 69.9% were woman. The nursing students' total mean score of SAHBTPB was 147.5 ± 14.0 (min = 94; max = 176). There was a positively significant association between the total score and students' gender, graduate level, and hand hygiene education status. There was no significant difference in scale total score mean based on the existence of dermatological problems on the students' hands or their frequency of hand hygiene (p > .05).

CONCLUSION

The mean scores of nursing students on the SAHBTPB were found to be at a good level. The sub-dimension "intention" was identified as an effective factor in predicting the hand hygiene behavior of the students. The findings have the potential to positively impact nursing education by increasing awareness among students and offering valuable insights for nurses and educators.

Methicillin-Resistant Staphylococcus aureus Carriage among Neonate Mothers, Healthcare Workers, and Environmental Samples in Neonatal Intensive Care Units: A Systematic Review

Background

Methicillin-resistant Staphylococcus aureus (MRSA) is a significant cause of morbidity and mortality among neonates admitted to neonatal intensive care units (NICUs). The MRSA colonization of neonates, attributed to various sources, including mothers, healthcare workers, and environmental surfaces, can lead to severe infection, prolonged hospital stays, and even death, imposing substantial economic burdens. Given the pressing need to mitigate MRSA spread in these vulnerable environments, further examination of the subject is warranted. This systematic review is aimed at synthesizing available evidence on MRSA carriage proportions among mothers of newborns, healthcare workers, and environmental surfaces in NICUs. Methodology. We included observational studies published in English or French from database inception to March 21, 2023. These studies focused on MRSA in nonoutbreak NICU settings, encompassing healthy neonate mothers and healthcare workers, and environmental surfaces. Literature search involved systematic scanning of databases, including Medline, Embase, Web of Science, Global Health, and Global Index Medicus. The quality of the selected studies was assessed using the Hoy et al. critical appraisal scale. The extracted data were summarized to calculate the pooled proportion of MRSA positives, with a 95% confidence interval (CI) based on the DerSimonian and Laird random-effects model.

Results

A total of 1891 articles were retrieved from which 16 studies were selected for inclusion. Most of the studies were from high-income countries. The pooled proportion of MRSA carriage among 821 neonate mothers across four countries was found to be 2.1% (95% CI: 0.3-5.1; I2 = 76.6%, 95% CI: 36.1-91.5). The proportion of MRSA carriage among 909 HCWs in eight countries was determined to be 9.5% (95% CI: 3.1-18.4; I2 = 91.7%, 95% CI: 87.1-94.6). The proportion of MRSA carriage among HCWs was highest in the Western Pacific Region, at 50.00% (95% CI: 23.71-76.29). In environmental specimens from five countries, a pooled proportion of 16.6% (95% CI: 3.5-36.0; I2 = 97.7%, 95% CI: 96.6-98.4) was found to be MRSA-positive.

Conclusion

With a significant heterogeneity, our systematic review found high MRSA carriage rates in neonate mothers, healthcare workers, and across various environmental surfaces in NICUs, posing a potential risk of nosocomial infections. Urgent interventions, including regular screening and decolonization of MRSA carriers, reinforcing infection control measures, and enhancing cleaning and disinfection procedures within NICUs, are crucial. This trial is registered with CRD42023407114.

Psychometric Testing of the Oncology Nurses Health Behaviors Determinants Scale: A Cross-Sectional Study

OBJECTIVES

Adherence by oncology nurses to chemotherapy safe handling guidelines is essential to prevent hazards of chemotherapy exposure. A review of the literature revealed the need for an instrument with evidence of reliability and validity to measure factors influencing adherence to safe chemotherapy-handling guidelines among oncology nurses. The purpose of this study was to psychometrically test the Oncology Nurses' Health Behaviors Determinants Scale (HBDS-ON) that measures the mentioned factors.

DATA SOURCES

Methodological research of a quantitative cross-sectional survey design was used. The study surveys were administered by email to a sample of 108 oncology nurses. Cronbach alpha, item analysis, exploratory factor analysis using principal axis factoring, and convergence validity testing were used to test reliability and validity.

CONCLUSION

Factor analysis yielded six subscales, each having acceptable internal consistency reliability (Cronbach alpha between 0.70 and 0.88). The subscales included four oncology nurse health beliefs (perceived threat, benefits, barriers, and self-efficacy), cues to action, and personal protective equipment availability and accessibility. Convergence validity testing results support the Oncology Nurses Health Behaviors Determinant Scale (HBDS-ON) construct validity. Oncology nurses' self-efficacy to adherence to chemotherapy-handling guidelines, the perceived barriers to adhere to chemotherapy-handling guidelines, and cues to action are associated with adherence to chemotherapy-handling guidelines.

IMPLICATIONS FOR NURSING PRACTICE

Oncology nurses' health beliefs, the cues to action, and personal protection equipment availability and accessibility are important determinants of nurses' adherence to chemotherapy-handling guidelines. The HBDS-ON is an instrument that has evidence of reliability and validity and could be used in practice to measure these determinants.

Navigating a Pandemic: Leadership Dynamics and Challenges within Infection Prevention and Control Units in Israel

This study investigates the impact of the coronavirus disease 2019 (COVID-19) pandemic on leadership within infection prevention and control (IPC) units across public hospitals in Israel. Through qualitative interviews with ten IPC managers from nine hospitals, equivalent to 30% of the country's acute care facilities, the research uncovers significant changes in managerial approaches due to the health crisis. The results reveal four main themes: (1) Enhanced managerial autonomy and leadership skills, with a noted rise in self-efficacy against the pandemic's backdrop; (2) Shifted perceptions of IPC units by upper management, recognizing their strategic value while identifying the need for a more profound understanding of IPC operations; (3) The increased emphasis on adaptability and rapid decision-making for effective crisis management; (4) The dual effect on job satisfaction and well-being, where greater commitment coincides with risks of burnout. The study underscores the essential nature of effective IPC leadership during emergencies, highlighting the need for clear communication, prompt action, and empathetic leadership. The conclusions point to the necessity for continuous research into IPC leadership, promoting strategic advancements in management to bolster IPC units against future health threats.

Perioperative Urinary Catheter Use and Association to (Gram-Negative) Surgical Site Infection after Spine Surgery

This study evaluates potential associations between the perioperative urinary catheter (UC) carriage and (Gram-negative) surgical site infections (SSIs) after spine surgery. It is a retrospective, single-center, case-control study stratifying group comparisons, case-mix adjustments using multivariate logistic regression analyses. Around half of the patients (2734/5485 surgeries) carried a UC for 1 day (median duration) (interquartile range, 1-1 days). Patients with perioperative UC carriage were compared to those without regarding SSI, in general, and Gram-negative, exclusively. The SSI rate was 1.2% (67/5485), yielding 67 revision surgeries. Gram-negative pathogens caused 16 SSIs. Seven Gram-negative episodes revealed the same pathogen concomitantly in the urine and the spine. In the multivariate analysis, the UC carriage duration was associated with SSI (OR 1.1, 95% confidence interval 1.1-1.1), albeit less than classical risk factors like diabetes (OR 2.2, 95%CI 1.1-4.2), smoking (OR 2.4, 95%CI 1.4-4.3), or higher ASA-Scores (OR 2.3, 95%CI 1.4-3.6). In the second multivariate analysis targeting Gram-negative SSIs, the female sex (OR 3.8, 95%CI 1.4-10.6) and a UC carriage > 1 day (OR 5.5, 95%CI 1.5-20.3) were associated with Gram-negative SSIs. Gram-negative SSIs after spine surgery seem associated with perioperative UC carriage, especially in women. Other SSI risk factors are diabetes, smoking, and higher ASA scores.

Personal protective behaviors in response to COVID-19: a longitudinal application of protection motivation theory

Introduction

Disease outbreaks are expected to occur more frequently and spread more rapidly in the age of globalization. Personal protective behaviors strongly affect infection and death rates worldwide. It is therefore of prime importance to better understand which factors predict personal protective behaviors during a pandemic. Protection motivation theory (PMT) proposes that people's motivation to protect themselves is based on two appraisal processes: threat appraisal and coping appraisal. Building on PMT, this longitudinal study aimed to predict personal protective behaviors in response to COVID-19, including hand hygiene, physical distancing, and mask wearing.

Method

In the first wave of the study (November, 2020), the two appraisal processes as specified in PMT as well as intentions to perform protective behaviors were assessed in a representative sample of German adults (N = 328). In the second wave of this study, which was conducted one month later, the frequency of protective behaviors was measured. Structural equation modeling was used to test whether threat and coping appraisal predicted intentions and protective behaviors.

Results

Response rate for the second wave was high (87%). For all three behaviors, self-efficacy predicted intentions and also indirectly behavior (i.e., mediated via intentions). Furthermore, exploratory tests of alternative theoretical models suggested that both self-efficacy and costs have direct effects (i.e., independent from their relationship with intentions) on performed behavior.

Conclusion

To support individuals to engage in protective behaviors during a pandemic, it is important to reduce barriers to action and to foster individuals' self-efficacy.

Knowledge, Attitude and Practice of Hand Hygiene among Healthcare Workers Caring for Children with Leukaemia in the Paediatric Oncology Ward of King Saud Medical City, Saudi Arabia

Background

Hands are the most common vehicle of pathogen transmission in a healthcare setting. Therefore, hand hygiene is the leading method of reducing healthcare-associated infections. This study aimed to determine the knowledge, attitude and practice (KAP) of hand hygiene and predictors for poor hand hygiene practice among healthcare workers who care for children with leukaemia in the paediatric oncology ward of King Saud Medical City (KSMC) in Saudi Arabia.

Methods

One hundred and ninety medical doctors and nurses, who were registered with the Saudi Commission for Health Specialities, were selected to participate in this cross-sectional study using a simple sampling technique. Their KAP of hand hygiene was assessed using a self-structured questionnaire and the collected data was analysed using IBM® SPSS® version 26.0.

Results

Of the 190 healthcare workers, 74.7% were nurses and 25.3% were medical doctors. Among the participants, 53.7% (102) had good knowledge of hand hygiene, 51.6% (98) had positive attitudes towards hand hygiene and 55.8% (106) practised satisfactory hand hygiene. Bachelor education level (adjusted OR = 2.736; 95% CI = 1.101, 6.799; P = 0.030), postgraduate education level (adjusted OR = 6.256; 95% CI = 2.171, 18.028; P = 0.001), poor knowledge (adjusted OR =2.575; 95% CI = 1.263, 5.246; P = 0.009) and negative attitude (adjusted OR = 4.702; 95% CI = 1.263, 5.246; P < 0.001) were the significant predictor variables of unsatisfactory hand hygiene practice among healthcare workers.

Conclusion

The performance of hand hygiene among healthcare workers is still far less than optimal, particularly in settings like oncology units. Effective programmes are needed to increase their awareness of hand hygiene KAP, while strict guidelines are needed to reduce nosocomial infections.

Hand-hygiene compliance: The importance of WHO's "moment 1" in prevention of healthcare-associated infections

BACKGROUND

Hand hygiene is the single most effective strategy for preventing healthcare associated infections (HCAI) but compliance is usually low and effective improvement strategies are needed. We assessed hand hygiene (HH) compliance with the World Health Organization (WHO) prescribed five moments of hand hygiene among health-care workers (HCW).

METHODS

A retrospective analysis of one-year data on hand hygiene was done. WHO single observer direct observation technique was used and HH compliance was noted among HCWS.

RESULTS

A total of 16,552 opportunities were recorded. Overall compliance as per WHO Guidelines was 69.2%. Sanitation worker had an adherence rate of 73.1% (95% confidence interval [CI]:70.6-75.4) followed by the nurses 71.2% (95% CI: 70.4-72.1). Physicians and technicians had a compliance rate of 64.9% (95% CI: 63.1-66.6) and 64% (95% CI: 60.1-67.9) respectively. Physiotherapists had a compliance rate of 62.2 (95% CI: 50.1-73.2) and the compliance of Phlebotomists was observed to be 23.1% (95% CI: 9.0-43.6). HCW stood best for WHO moment 5 and worst for moment 1 with compliance of 79.1% (95% CI:77.4-80.7) and 55.8% (95% CI:54.5-57.1) respectively.

DISCUSSION

The moment 1 of the WHO's five moments is the most important for preventing the transmission of resistant pathogens between patients. Missed opportunities in moment 1 need to be focused on while planning new strategies to promote hand hygiene.

Evaluating Therapeutic Healthcare Environmental Criteria: Architectural Designers' Perspectives

This study presents architectural designers’ perception of the importance of healthcare environmental criteria in the implementation of user-centered, therapeutic hospital design. Architectural designers with over three years of professional experience (N = 182) in South Korea were surveyed using an empirical questionnaire. The extensive interviews of 15 hospital design experts followed to interpret the survey results and discuss the barriers and suggestions for the successful delivery of therapeutic healthcare design practice. Among the 27 variables selected from the preliminary literature review, factor analyses revealed seven important therapeutic environmental criteria (i.e., management, interior design, spatial quality, service, nature and rest, ambient indoor comfort, and social program and space; χ2 = 1783.088, df = 300, p < 0.001). Analyses of variance revealed the level of importance among these criteria related to respondents’ personal and professional characteristics. Significant differences were found for the variables from the management, interior design, and spatial quality factors in relation to the respondents sex and age. For the successful delivery of therapeutic healthcare design, the design experts highlighted the implementation of evidence-based design practice that integrates local and international knowledge from various hospital users and multi-disciplinary specialists participating in the healthcare design process.

Are there reasons behind high Handrub consumption? A French National in-depth qualitative assessment

Background

Hand hygiene (HH) is the most important measure for preventing healthcare-associated infections. A significant correlation between alcohol-based handrub consumption (AHRC) and observed HH compliance rates has been established. In France, publicly reported AHRC displayed a large heterogeneity across healthcare facilities (HCFs). We aimed to describe programmes for promoting HH in the top and medium AHRC scorers and to assess factors and drivers leading to a high AHRC score in a panel of French HCFs.

Methods

We performed a nationwide qualitative comparative case study based on in-depth semi-structured interviews in 16 HCFs with high, 4-year AHRC scores, and a sample of seven university hospitals (UHs) with medium AHRC scores. Infection Prevention and Control Team (IPC) members (n = 62), quality managers/chief executive officers (n = 23) and frontline workers (n = 6) were interviewed, using a grounded theory approach and an iterative thematic approach.

Results

Ninety-one interviews were performed. There was a large heterogeneity in IPC structures and objectives, with specific patterns associated with high AHRC that were more organisational than technical. Four areas emerged: (1) strong cohesive team structure with supportive and outcome-oriented work attitude, (2) IPC structure within the organization, (3) active support from the institution, (4) leadership and role model. Among high AHRC scorers, a good core IPC organisation, a proactive and flexible management, a frequent presence in the clinical wards, and working in a constructive safety climate were prominent.

Conclusion

We highlighted that IPC structure and activity is heterogeneous, with organisational and behavioural characteristics associated with high AHRC score. Beyond technical challenge, our work underlines the importance of strong structure of the IPC and behavioural approaches in implementing key IPC programmes.

Measuring the Self-Efficacy of Health Professionals for Practicing Hand Hygiene and Using Gloves: Development and Validation of an Instrument

Adherence to hand hygiene procedures and the use of gloves is a problem that deserves to be analyzed from an individual and organizational point of view. For this, we aim to develop and validate an instrument for measuring the self-efficacy of health professionals for practicing hand hygiene and using gloves. We evaluated the metric properties of validity and reliability for measuring the self-efficacy of health professionals for practicing hand hygiene and using gloves. Fifteen health and education professionals formed the judges committee to construct the instrument for measuring the self-efficacy of health professionals for practicing hand hygiene and using gloves. Moreover, 362 nursing professionals participated in this study that was carried out from 2017 to 2020. The construct validity by known groups was confirmed by comparing the means of self-efficacy of the self-efficacy of health professionals for practicing hand hygiene and using gloves with the variables sex and unit of activity. The convergent construct validity showed a weak correlation between the scores of the self-efficacy of health professionals for practicing hand hygiene and using gloves instrument, and the perceived general self-efficacy scale. This instrument is easy to apply and can be used in the assessment of behavioral determinants, regarding hand hygiene and the use of gloves, in other health professionals, considering the generalization and scope of the items.

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.

Mothers' hygiene experiences in confinement centres: A cohort study

Introduction

Ethnic Malaysian Chinese used to observe the 1-month postpartum confinement period at home and many families would engage a traditional postpartum carer to help care for the mother and newborn. A recent trend has been the development of confinement centres (CCs) which are private non-healthcare establishments run by staff not trained in health care. Concerns about hygiene in CCs arose after infections were reported. We describe the practice of hand hygiene observed in CCs, the availability of resources for hygiene, and the prevalence of health-related problems in CCs.

Methods

This is a cohort study of ethnic Chinese mothers intending to breastfeed their healthy infants. They were recruited post-delivery along with a comparison group who planned to spend their confinement period at home. After their 1-month confinement period, they were contacted for a structured telephone interview about their experience. To avoid any alteration in behaviour, mothers were not told at recruitment that they had to observe hygiene practices. Multiple logistic regression was used to assess the effect of place of confinement on rates of infant health problems.

Results

Of 187 mothers, 88(47%) went to 27 different CCs while 99(53%) stayed at home. Response rates for the 1-month interviews were 88%(CC) versus 97%(home). Mothers in CC group stayed in one to four-bedded rooms and 92% of them had their baby sleeping separately in a common nursery described to have up to 17 babies at a time; 74% of them spent less than six hours a day with their babies; 43% noticed that CC staff had inadequate hand hygiene practices; 66% reported no hand basins in their rooms; 30% reported no soap at hand basins; 28% reported inexperienced or inadequate staff and 4% reported baby item sharing. Among the mothers staying at home, 35% employed a traditional postpartum carer for her baby; 32% did not room-in with their babies, but only 11% spent less than 6 hours a day with their babies. Of mothers who employed traditional postpartum carers, 32% did not know if their carer washed hands after changing diapers and 18% reported that their carer did not. Health problems that were probably related to infection (HPRI) like fever and cough were similar between the groups: 14%(CC) versus 14%(home) (p = 0.86). Multiple logistic regression did not show that CCs were a factor for HPRI: aOR 1.28 (95% CI 0.36 to 4.49). Three mothers reported events that could indicate transmission of infection in CCs.

Conclusion

We found unsatisfactory hygiene practices in CCs as reported by mothers who spent their confinement period there. Although we were not able to establish any direct evidence of infection transmission but based on reports given by the mothers in this study, it is likely to be happening. Therefore, future studies, including intervention studies, are urgently needed to establish an appropriate hygiene standard in CCs as well as the best method to implement this standard. Training CC staff with hygiene knowledge so that they can be empowered to contribute to the development of these standards would be important.

Knowledge and perception of hand hygiene: A survey using WHO standardized tools in Tehran, Iran

BACKGROUND

Proper hand hygiene is the most important action in preventing healthcare-associated infections (HCAIs). In this study, the knowledge and perception of hand hygiene assessed among nurses as the most exposed personnel to patients.

METHODS

In this analytical cross-sectional study, the nurses working in different wards of a collegiate tertiary hospital in Tehran were investigated by standardized WHO questionnaires.

RESULTS

Of the 101 participating nurses 89 (88.1%) were females. 81 (80.2%) had received formal related training. The 69 respondents estimated the mean prevalence of HCAI to be 38.91% and 98 (97.1%) considered hand hygiene an effective prevention in this regard. 78 (77.3%) perceived hand hygiene as the center priority; 82, 83 and 79 of participants would think that good hand hygiene matters for their superiors, colleagues and patients, respectively. The practice of hand hygiene was stated to be difficult by 48 (47.5%) respondents. There was no significant difference in self-reporting of hand hygiene practice among nurses in age (P=0.68), the degree of education (P=0.574), work experience (P=0.64), nor their wards (P=0.131). There was a significant reverse relationship with the supposed difficulty level of doing hand hygiene (P=0.049). The mean score of the nurses' knowledge was 66.53 (±9.41) based on the answers to the questions of the knowledge questionnaire.

CONCLUSION

Knowledge and perception of hand hygiene, as this study showed, might not to be satisfactory; therefore, planning to improve these indicators and regular monitoring using standard tools is necessary for all healthcare centers.

COVID-19 and handwashing: Implications for water use in Sub-Saharan Africa

Because the main modes of transmission of the COVID-19 virus are respiration and contact, WHO recommends frequent washing of hands with soap under running water for at least 20 s. This article investigates how the level of concern about COVID-19 affects the likelihood of washing hands frequently in sub-Saharan Africa. We discuss the implication of the findings for water-scarce environment. The study makes use of a unique survey dataset from 12 sub-Saharan African countries collected in April 2020 (first round) and May 2020 (second round) and employs an extended ordered probit model with endogenous covariate. The results show that the level of concern about the spread of the virus increases the likelihood of washing hands with soap under running water for a minimum of 20 s at least five times a day. The increase in the probability of handwashing due to concern about COVID-19, ranges from 3% for Benin to 6.3% for South Africa. The results also show heterogeneous effects across gender- and age-groups, locality and various water sources. However, in Africa, the sustainability of the handwashing protocol could be threatened by the severe water scarcity that exists in the region. To sustain frequent handwashing, sub-Saharan Africa needs an effective strategy for water management and supply.

Impact of a total lockdown for pandemic SARS-CoV-2 (Covid-19) on deep surgical site infections and other complications after orthopedic surgery: a retrospective analysis

BACKGROUND

A total lockdown for pandemic SARS-CoV-2 (Covid-19) entailed a restriction of elective orthopedic surgeries in Switzerland.  While access to the hospital and human contacts were limited, hygiene measures were intensified. The objective was to investigate the impact of those strict public health guidelines on the rate of intra-hospital, deep surgical site infections (SSI), wound healing disorders and non-infectious postoperative complications after orthopedic surgery during the first Covid-19 lockdown.

METHODS

In a single-center study, patients with orthopedic surgery during the first Covid-19 lockdown from March 16, 2020 to April 26, 2020 were compared to cohorts that underwent orthopedic intervention in the pre- and post-lockdown periods of six months each. Besides the implementation of substantial public health measures (promotion of respiratory etiquette and hand hygiene), no additional infection control bundles have been implemented.

RESULTS

5791 patients were included in this study. In multivariate Cox regression analyses adjusting for the large case-mix, the lockdown was unrelated to SSI (hazard ratio (HR) 1.6; 95% confidence interval (CI) 0.6-4.8), wound healing disorders (HR 0.7; 95% CI 0.1-5.7) or other non-infectious postoperative complications (HR 0.7, 95% CI 0.3-1.5) after a median follow-up of seven months.

CONCLUSION

The risks for SSI, wound healing disorders and other complications in orthopedic surgery were not influenced by the extended public health measures of the total Covid-19 lockdown. Trial registration BASEC 2020-02646 (Cantonal Ethics Commission Zurich).

Knowledge and Perceptions about COVID-19 among Health Care Workers: Evidence from COVID-19 Hospitals during the Second Pandemic Wave

Health care workers (HCWs) face a higher risk of infection, since they work at the front line of COVID-19 patients' management. Misinterpretations of current scientific evidence among HCWs may impact the delivery of appropriate care to COVID-19 patients and increase the risk of SARS-CoV-2 transmission in the hospital setting. Moreover, knowledge may affect HCWs perceptions depending on their broad beliefs and past experiences. The aim of this study was to explore the knowledge and perceptions of HCWs regarding COVID-19 issues during the second wave of the pandemic. A cross-sectional survey, involving a printed questionnaire, was conducted from 21 October 2020 to 31 January 2021 in four tertiary care hospitals located at four distant geographical regions in Greece. In total, 294 HCWs participated in this study. The majority of HCWs provided precise responses regarding general knowledge, perceptions, and practices concerning the COVID-19 pandemic. However, responses on hand hygiene and antimicrobial use in HCWs with COVID-19 were mistaken. This study reveals a certain degree of misconceptions and knowledge gaps in HCWs everyday practice, especially regarding hand hygiene and antimicrobial use in COVID-19 patients.

Self-Reported Use of Personal Protective Equipment among Emergency Department Nurses, Physicians and Advanced Practice Providers during the 2020 COVID-19 Pandemic

Background: Emergency departments (EDs) have seen dramatic surges in patients infected with COVID-19 and are high-risk transmission environments. Knowledge, attitudes and practice regarding personal protective equipment (PPE) among ED health care workers (HCWs) during the COVID-19 pandemic have not been studied, thus this study examines this knowledge gap. Methods: This was a cross-sectional survey of 308 HCWs in two urban EDs in Atlanta, Georgia in April and May of 2020. Results: We surveyed 308 HCWs; 137 responded (44% response rate). All HCWs reported adequate knowledge and 96% reported compliance with PPE guidelines. Reported sources of PPE information: 56.7% charge nurse, 67.3% the institutional COVID-19 website. Frequency of training was positively associated with understanding how to protect themselves and patients (OR = 1.7, 95% CI: 1.0–2.9). Conclusions: Few HCWs are willing to care for patients without PPE, and therefore we should aim for resiliency in the PPE supply chain. EDs should consider multiple communication strategies, including a website with concise information and enhanced training for key personnel, particularly the charge nurse. Attention to frequency in HCW training may be key to improve confidence in protecting themselves and patients. Findings can be leveraged by EDs to implement effective PPE training.

Utilizing behavioral theories to explain hospital visitors' observed hand hygiene behavior

BACKGROUND

Hand hygiene is essential for infection prevention. This study aimed to find a suitable theoretical model and identify critical facilitators and barriers to explain hospital visitors' hand hygiene practice.

METHODS

Visitors in 4 hospitals were observed and asked to give explanations for using or not using the hand rub dispenser. The written explanations of N = 838 participants were coded according to three theoretical models: Theory of Planned Behavior, Health Action Process Approach (HAPA), and Theoretical Domains Framework (TDF).

RESULTS

Self-reported hand hygiene behavior differed from observed behavior, with 15.75% wrongly claiming to have cleaned their hands. Critical facilitators for hand hygiene were attitude toward the behavior,subjective norm, outcome expectancies, risk perception, planning, action control, knowledge and skills, motivation and goals, and social influences. Key barriers included perceived behavioral control; barriers and resources; memory, attention, and decision processes; and environmental context and resources.

CONCLUSIONS

Visitors' self-reported hand hygiene behavior is over-reported. Both HAPA and TDF were identified as suitable theoretical models for explaining visitor's hand hygiene practice. Future behavior change interventions should focus on (1) visibility and accessibility of cleaning products; (2) informing laypeople about their role regarding infection prevention; and (3) leveraging social influence processes.

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.

Hand-hygiene-related clinical trials reported between 2014 and 2020: a comprehensive systematic review

BACKGROUND

There is general consensus that hand hygiene is the most effective way to prevent healthcare-associated infections. However, low rates of compliance amongst healthcare workers have been reported globally. The coronavirus disease 2019 pandemic has further emphasized the need for global improvement in hand hygiene compliance by healthcare workers.

AIM

This comprehensive systematic review provides an up-to-date compilation of clinical trials, reported between 2014 and 2020, assessing hand hygiene interventions in order to inform healthcare leaders and practitioners regarding approaches to reduce healthcare-associated infections using hand hygiene.

METHODS

CINAHL, Cochrane, EMbase, Medline, PubMed and Web of Science databases were searched for clinical trials published between March 2014 and December 2020 on the topic of hand hygiene compliance among healthcare workers. In total, 332 papers were identified from these searches, of which 57 studies met the inclusion criteria.

FINDINGS

Forty-five of the 57 studies (79%) included in this review were conducted in Asia, Europe and the USA. The large majority of these clinical trials were conducted in acute care facilities, including hospital wards and intensive care facilities. Nurses represented the largest group of healthcare workers studied (44 studies, 77%), followed by physicians (41 studies, 72%). Thirty-six studies (63%) adopted the World Health Organization's multi-modal framework or a variation of this framework, and many of them recorded hand hygiene opportunities at each of the 'Five Moments'. However, recording of hand hygiene technique was not common.

CONCLUSION

Both single intervention and multi-modal hand hygiene strategies can achieve modest-to-moderate improvements in hand hygiene compliance among healthcare workers.

How good are clinicians in predicting the presence of Pseudomonas spp. in diabetic foot infections? A prospective clinical evaluation

Introduction

The most frequently prescribed empirical antibiotic agents for mild and moderate diabetic foot infections (DFIs) are amino-penicillins and second-generation cephalosporins that do not cover Pseudomonas spp. Many clinicians believe they can predict the involvement of Pseudomonas in a DFI by visual and/or olfactory clues, but no data support this assertion.

Methods

In this prospective observational study, we separately asked 13 experienced (median 11 years) healthcare workers whether they thought the Pseudomonas spp. would be implicated in the DFI. Their predictions were compared with the results of cultures of deep/intraoperative specimens and/or the clinical remission of DFI achieved with antibiotic agents that did not cover Pseudomonas.

Results

Among 221 DFI episodes in 88 individual patients, intraoperative tissue cultures grew Pseudomonas in 22 cases (10%, including six bone samples). The presence of Pseudomonas was correctly predicted with a sensitivity of 0.32, specificity of 0.84, positive predictive value of 0.18 and negative predictive value 0.92. Despite two feedbacks of the interim results and a 2-year period, the clinicians' predictive performance did not improve.

Conclusion

The combined visual and olfactory performance of experienced clinicians in predicting the presence of Pseudomonas in a DFI was moderate, with better specificity than sensitivity, and did not improve over time. Further investigations are needed to determine whether clinicians should use a negative prediction of the presence of Pseudomonas in a DFI, especially in settings with a high prevalence of pseudomonal DFIs.

Hand(y) hygiene insights: Applying three theoretical models to investigate hospital patients' and visitors' hand hygiene behavior

BACKGROUND

Improving hand hygiene in hospitals is the most efficient method to prevent healthcare-associated infections. The hand hygiene behavior of hospital patients and visitors is not well-researched, although they pose a risk for the transmission of pathogens. Therefore, the present study had three aims: (1) Finding a suitable theoretical model to explain patients' and visitors' hand hygiene practice; (2) Identifying important predictors for their hand hygiene behavior; and (3) Comparing the essential determinants of hand hygiene behavior between healthcare professionals from the literature to our non-professional sample.

METHODS

In total N = 1,605 patients and visitors were surveyed on their hand hygiene practice in hospitals. The employed questionnaires were based on three theoretical models: a) the Theory of Planned Behavior (TPB); b) the Health Action Process Approach (HAPA); and c) the Theoretical Domains Framework (TDF). Structural equation modeling was used to analyze the data. To compare our results to the determinants of healthcare workers' hand hygiene behavior, we searched for studies that used one of the three theoretical models.

RESULTS

Among patients, 52% of the variance in the hand hygiene behavior was accounted for by the TDF domains, 44% by a modified HAPA model, and 40% by the TPB factors. Among visitors, these figures were 59%, 37%, and 55%, respectively. Two clusters of variables surfaced as being essential determinants of behavior: self-regulatory processes and social influence processes. The critical determinants for healthcare professionals' hand hygiene reported in the literature were similar to the findings from our non-professional sample.

CONCLUSIONS

The TDF was identified as the most suitable model to explain patients' and visitors' hand hygiene practices. Patients and visitors should be included in existing behavior change intervention strategies. Newly planned interventions should focus on targeting self-regulatory and social influence processes to improve effectiveness.

Exploring determinants of hand hygiene compliance in LTCFs: a qualitative study using Flottorps' integrated checklist of determinants of practice

BACKGROUND

Elderly residents in long-term care facilities (LTCFs) are vulnerable to healthcare-associated infections. Although hand hygiene is a leading measure for preventing infection, the compliance of healthcare workers is low. The aim of this study is to identify determinants that influence hand hygiene compliance of nursing staff in LTCFs. This information on determinants can eventually be used to develop a tailored implementation strategy for LTCFs.

METHODS

This is an explorative, descriptive study using qualitative methods. We performed semi-structured focus group discussions with 31 nurses and nurse assistants from five Dutch LTCFs. Our focus group discussions continued until no new information could be identified from the data. We used Flottorps' comprehensive checklist for identifying determinants of practice (the TICD checklist) to guide data collection and analysis. The audiotapes were transcribed verbatim and two authors independently analysed the transcripts with Atlas.ti software.

RESULTS

LTCFs for the elderly have setting specific determinants that are decisive in explaining hand hygiene compliance. Most of these determinants are related to the residents with whom nurses build close relationships and for whom they want to create a homelike atmosphere. Residents can complicate the provision of care with unpredictable behaviour, being unwilling to receive care or use shared facilities. Our study also discovered setting-transcending determinants related to knowledge, professional interactions, guidelines, and incentives/resources.

CONCLUSIONS

Nurses in LTCFs are constantly pursuing a balance between working hygienically, responding adequately to acute care needs, and maintaining a homelike environment for their residents. As a result, setting-specific determinants affect hand hygiene compliance, as do the known determinants that are important in other care settings. To improve compliance in LTCFs, interventions should be selected on a theoretical base while linking these determinants to change interventions.

The effect of behavioural interventions targeting hand hygiene practices among nurses in high-income hospital settings: a systematic review

BACKGROUND

Hand hygiene is a critical behaviour for infection control but efforts to raise compliance among clinical professionals have been met with mixed success. The aim of this systematic review was to identify the effectiveness of the behaviour change techniques utilised in recent hand hygiene interventions that seek to improve hand hygiene compliance among nurses in hospitals in high-income countries. Nurses are at the frontline of healthcare delivery, and so improving their HH behaviour and thus increasing HHC rates will have a relatively large impact on reducing transmission and preventing healthcare acquired infections.

METHODS

High-quality studies among nurses in high-income countries were surveyed from the scientific literature, following PRISMA guidelines, to identify which kinds of behaviour change mechanisms have been used to effectively increase hand hygiene compliance. Only seven studies met all inclusion criteria. A formal meta-analysis was not conducted due to the heterogeneity of the included studies. Instead, the review analysed studies in line with the Intervention Component Analysis approach to identify which differences in intervention characteristics appear to be important. Analysis proceeded in two steps: first, the Effective Practice and Organization of Care Data Extraction Checklist was used to identify the study design and to describe the intervention, target population, setting, results, outcome measures, and analytic approach. The second step involved inferring the behavioural change techniques used in the complex study interventions. Following coding, logic models were then inferred for each study to identify the Theory of Change behind each intervention. These Theories of Change were then examined for suggestions as to which BCTs were likely to have been responsible for any effectiveness observed.

RESULTS

Goals and planning (to achieve specific ends), comparison of behaviour (to peers or some ideal) and feedback and monitoring (observing and providing feedback about behaviour or outcomes) were the most frequently used behaviour change technique groupings used across studies and within interventions.

CONCLUSION

The complexity of the interventions used and lack of sufficient studies makes assignment of responsibility for behaviour change to specific behaviour change techniques difficult. Delivery channels and activities identified in the study Theories of Change were also highly individualized and so difficult to compare. However, we identified a temporal shift in types of techniques used in these recent studies on HH interventions, as compared with studies from prior to the review period. These newer interventions did not focus on providing access to alcohol-based hand rub or trying to solely encourage administrative support. Instead, they had nurses create goals and plan how to best facilitate HH, compared both individuals' and the group's behaviour to others, and focused on providing feedback.

Nurses' Attitudes and Perceptions towards Hand Hygiene in Mental Health and Medical Inpatient Settings: Comparative, Cross-Sectional Study

Poor hand hygiene is a major contributor to hospital acquired infection. In this study, a comparison of the related attitudes of psychiatric and non-psychiatric nurses was made using a cross-sectional survey design. N = 79 nurses who work in psychiatric or non-psychiatric hospital wards completed questionnaires regarding intended compliance with hand-washing protocols and potential cognitive predictors of compliance. Perceived ease of compliance and behavioural norms, and working in a non-psychiatric ward, predicted superlative intended compliance. Working in psychiatry did not in itself predict outgroup membership suggesting that psychiatric ward-related factors, rather than psychiatric nurse-related factors are most relevant in determining between-group differences. Consideration of factors unique to psychiatry wards during service design could improve compliance.

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.

A behaviour change package to prevent hand dermatitis in nurses working in health care: the SCIN cluster RCT

BACKGROUND

Although strategies have been developed to minimise the risk of occupational hand dermatitis in nurses, their clinical effectiveness and cost-effectiveness remain unclear.

OBJECTIVES

The Skin Care Intervention in Nurses trial tested the hypothesis that a behaviour change package intervention, coupled with provision of hand moisturisers, could reduce the point prevalence of hand dermatitis when compared with standard care among nurses working in the NHS. The secondary aim was to assess the impact of the intervention on participants' beliefs and behaviour regarding hand care, and the cost-effectiveness of the intervention in comparison with normal care.

DESIGN

Cluster randomised controlled trial.

SETTING

Thirty-five NHS hospital trusts/health boards/universities.

PARTICIPANTS

First-year student nurses with a history of atopic tendency, and full-time intensive care unit nurses.

INTERVENTION

Sites were randomly allocated to be 'intervention plus' or 'intervention light'. Participants at 'intervention plus' sites received access to a bespoke online behaviour change package intervention, coupled with personal supplies of moisturising cream (student nurses) and optimal availability of moisturising cream (intensive care unit nurses). Nurses at 'intervention light' sites received usual care, including a dermatitis prevention leaflet.

MAIN OUTCOME MEASURE

The difference between intervention plus and intervention light sites in the change of point prevalence of visible hand dermatitis was measured from images taken at baseline and at follow-up.

RANDOMISATION

Fourteen sites were randomised to the intervention plus arm, and 21 sites were randomised to the intervention light arm.

BLINDING

The participants, trial statistician, methodologist and the dermatologists interpreting the hand photographs were blinded to intervention assignment.

NUMBERS ANALYSED

An intention-to-treat analysis was conducted on data from 845 student nurses and 1111 intensive care unit nurses.

RESULTS

The intention-to-treat analysis showed no evidence that the risk of developing dermatitis was greater in the intervention light group than in the intervention plus group (student nurses: odds ratio 1.25, 95% confidence interval 0.59 to 2.69; intensive care unit nurses: odds ratio 1.41, 95% confidence interval 0.81 to 2.44). Both groups had high levels of baseline beliefs about the benefits of using hand moisturisers before, during and after work. The frequency of use of hand moisturisers before, during and after shifts was significantly higher in the intensive care unit nurses in the intervention plus arm at follow-up than in the comparator group nurses. For student nurses, the intervention plus group mean costs were £2 lower than those for the comparator and 0.00002 more quality-adjusted life-years were gained. For intensive care unit nurses, costs were £4 higher and 0.0016 fewer quality-adjusted life-years were gained.

HARMS

No adverse events were reported.

LIMITATIONS

Only 44.5% of participants in the intervention plus arm accessed the behaviour change package.

CONCLUSION

The intervention did not result in a statistically significant decrease in the prevalence of hand dermatitis in the intervention plus group.

FUTURE WORK

Participants had a high level of baseline beliefs about the importance of using hand moisturisers before, during and after work. Future research should focus on how workplace culture can be changed in order for that knowledge to be actioned.

Baseline assessment of hand hygiene knowledge perception: An observational study at a newly set up teaching hospital

Background:

Hand hygiene plays a crucial role in preventing health-care-associated infections (HCAIs) by reducing the spread of antimicrobial resistance. But, its compliance with optimal practices usually remains low at most of our health-care settings.

Aim:

This study focused on one of the primordial, basic and low-cost practice of infection control.

Materials and Methods:

A cross-sectional observational study was conducted among medical faculty, senior residents, postgraduates, nursing faculty, ward sisters/matron, and staff nurses at All India Institute of Medical Sciences (AIIMS), Rishikesh, Uttarakhand. Data were collected on a pretested structured questionnaire distributed among the participants, which consisted of questions to assess the knowledge and perception toward hand hygiene.

Results:

A total of 171 health-care workers (HCWs) were assessed in this study. Overall response rate observed was 87.8% ± 11.6%. Majority of the participants were staff nurses. Approximately 55% of them had received formal hand hygiene training in the last 3 years. Overall correct knowledge seen among participants was 66.4% ± 27.5%. It was observed that in situations requiring hand hygiene, it was performed in approximately 70%–80% of the times. Alcohol-based hand rub was not available at every point of care, whereas single-use towel was not present at every sink. When monitored whether the HCW started hand hygiene activity or not, compliance was seen in only 32% of the total.

Conclusion:

It is now essential for developing countries to formulate the policies for implementation of basic infection control practices. As we are facing an era of multidrug-resistant pathogens that are rapidly increasing globally, and paucity of availability of new antimicrobials, it is been essential to look at the role of basic infection control practices at health-care settings and implement them at priority level.

Improving Hand Hygiene Compliance in Nursing Homes: Protocol for a Cluster Randomized Controlled Trial (HANDSOME Study)

BACKGROUND

Hand hygiene compliance is considered the most (cost-)effective measure for preventing health care-associated infections. While hand hygiene interventions have frequently been implemented and assessed in hospitals, there is limited knowledge about hand hygiene compliance in other health care settings and which interventions and implementation methods are effective.

OBJECTIVE

This study aims to evaluate the effect of a multimodal intervention to increase hand hygiene compliance of nurses in nursing homes through a cluster randomized controlled trial (HANDSOME study).

METHODS

Nursing homes were randomly allocated to 1 of 3 trial arms: receiving the intervention at a predetermined date, receiving the identical intervention after an infectious disease outbreak, or serving as a control arm. Hand hygiene was evaluated in nursing homes by direct observation at 4 timepoints. We documented compliance with the World Health Organization's 5 moments of hand hygiene, specifically before touching a patient, before a clean/aseptic procedure, after body fluid exposure risk, after touching a patient, and after touching patient surroundings. The primary outcome is hand hygiene compliance of the nurses to the standards of the World Health Organization. The secondary outcome is infectious disease incidence among residents. Infectious disease incidence was documented by a staff member at each nursing home unit. Outcomes will be compared with the presence of norovirus, rhinovirus, and Escherichia coli on surfaces in the nursing homes, as measured using quantitative polymerase chain reaction.

RESULTS

The study was funded in September 2015. Data collection started in October 2016 and was completed in October 2017. Data analysis will be completed in 2020.

CONCLUSIONS

HANDSOME studies the effectiveness of a hand hygiene intervention specifically for the nursing home environment. Nurses were taught the World Health Organization's 5 moments of hand hygiene guidelines using the slogan "Room In, Room Out, Before Clean, After Dirty," which was developed for nursing staff to better understand and remember the hygiene guidelines. HANDSOME should contribute to improved hand hygiene practice and a reduction in infectious disease rates and related mortality.

Hand Hygiene Among Doctors in Transplant Departments in Poland: A Cross-sectional Survey

INTRODUCTION

Hand hygiene (HH) is often under-discussed in clinical work, but it is hard to overestimate its role in preventing health care associated infections (HCAIs), especially among immunocompromised populations such as transplant patients.

OBJECTIVES

This study aimed to investigate the compliance of doctors in transplant departments in Poland with HH and other selected infection control measures.

MATERIAL AND METHODS

An on-line cross-sectional survey was carried out among doctors from all Polish transplant departments listed by POLTRANSPLANT. The questionnaire addressed HH in different clinical settings and based on the World Health Organization (WHO) "My 5 Moments for Hand Hygiene."

RESULTS

Completed questionnaires were obtained from 204 physicians (49% women; response rate: 24.7%). The lowest proportion of doctors who always comply with HH was observed in 2 out of 5 critical moments for hand hygiene: "before touching a patient" (40.2%) and "after contact with patient surroundings" (21.6%). Most respondents declared correct HH action that they would apply in a particular clinical situation as listed in the survey. More than half of doctors (57.4%) declared disinfecting stethoscopes "before and/or after each use." The lack of alcohol-based hand-rub nearby or nonfunctional containers, daily rush, and occurring emergencies were identified as the main reasons for noncompliance with HH recommendations.

CONCLUSION

Doctors in transplant departments in Poland have a satisfactory level of knowledge about HH in various situations. However, further organizational and educational activities are needed to promote compliance with HH recommendations in health care facilities.

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.

"Infection prevention and control idea challenge" contest: a fresh view on medical education and problem solving

Background

Healthcare-associated infections (HAIs) challenge modern medicine. Considering their high prevalence in Iran, we aimed to provide knowledge on the subject, and to teach about the importance of infection prevention and control (IPC) to a broad audience of pre-graduate healthcare professionals, focusing on education as the cornerstone of IPC.

Main body

We invited Iranian medical students to present ideas on “how to reduce HAIs.” Projects were eligible if being original and addressing the call. Accepted projects were quality assessed using a scoring system. Forty-nine projects were submitted, of which 37 met the inclusion criteria. They had a mean score of 69.4 ± 18.3 out of the maximum possible score of 115. Four reviewers assessed the 37 projects for clinical applicability, impact on patient safety, and innovation, and selected the best 12 to compete at the 2nd International Congress on Prevention Strategies for Healthcare-associated Infections, Mashhad, Iran, 2018. The competition took place in three rounds. The selected teams presented their projects in the first round and debated one by one in a knockout manner, while the jury reviewed their scientific content and presentation skills. In the second round, the top 5 projects competed for reaching the final stage, in which the teams presented their ideas in front of a panel of international IPC experts to determine the first three ranks. At the end of the contest, the participants gained valuable criticisms on how to improve their ideas. Moreover, by its motivating atmosphere, the contest created an excellent opportunity to promote IPC in medical schools.

Conclusions

Using innovation contests in pre-graduates is an innovative education strategy. It sensitizes medical students to the challenges of IPC and antimicrobial resistance and drives them to think about solutions. By presenting and defending their innovations, they deepen their understanding on the topic and generate knowledge transfer in both ways, from students to teachers and vice versa.

A family empowerment strategy is associated with increased healthcare worker hand hygiene in a resource-limited setting

BACKGROUND

Guidelines recommend empowering patients and families to remind healthcare workers (HCWs) to perform hand hygiene (HH). The effectiveness of empowerment tools for patients and their families in Southeast Asia is unknown.

METHODS

We performed a prospective study in a pediatric intensive care unit (PICU) of a Vietnamese pediatric referral hospital. With family and HCW input, we developed a visual tool for families to prompt HCW HH. We used direct observation to collect baseline HH data. We then enrolled families to receive the visual tool and education on its use while continuing prospective collection of HH data. Multivariable logistic regression was used to identify independent predictors of HH in baseline and implementation periods.

RESULTS

In total, 2,014 baseline and 2,498 implementation-period HH opportunities were observed. During the implementation period, 73 families were enrolled. Overall, HCW HH was 46% preimplementation, which increased to 73% in the implementation period (P < .001). The lowest HH adherence in both periods occurred after HCW contact with patient surroundings: 16% at baseline increased to 24% after implementation. In multivariable analyses, the odds of HCW HH during the implementation period were significantly higher than baseline (adjusted odds ratio [aOR], 2.94; 95% confidence interval [CI], 2.54-3.41; P < .001) after adjusting for observation room, HCW type, time of observation (weekday business hours vs evening or weekend), and HH moment.

CONCLUSIONS

The introduction of a visual empowerment tool was associated with significant improvement in HH adherence among HCWs in a Vietnamese PICU. Future research should explore acceptability and barriers to use of similar tools in low- and middle-income settings.

User-centred participatory design of visual cues for isolation precautions

Background

Isolation precautions are intended to prevent transmission of infectious agents, yet healthcare provider (HCP) adherence remains suboptimal. This may be due to ambiguity regarding the required precautions or to cognitive overload of HCPs. In response to the challenge of changing HCP behaviour, increasing attention should be paid to the role of engineering controls and facility design that incorporate human factors elements. In the current study, we aimed to develop an isolation precaution signage system that provides visual cues, serves as a cognitive aid at the point of care, and removes ambiguity regarding which precautions are necessary (e.g. masks, gowns, gloves, single rooms) when caring for isolated patients.

Methods

We employed a user-centred, participatory design approach in which HCPs were actively involved in generating an isolation precaution signage system based on human factors design principles. HCPs were purposefully sampled for each design phase to include a representative sample of potential system users. We conducted front-end analysis through interviews and observations to identify challenges related to the existing signage and to establish design requirements for new signage. This was followed by the creation of user personas, design thinking workshops, and prototyping, which then underwent iterative cycles of evaluation. Graphical symbols were developed and tested for comprehensibility.

Results

Front-end analysis revealed several barriers to use of the current signage system such as unclear target audience, low signal-to-noise ratio, and ambiguity regarding the applicable precautions. A comprehensive list of design requirements was generated. The project ultimately resulted in a collection of validated, comprehensible symbols and signs for contact, droplet, and airborne isolation, as well as the identification of several systems-level solutions for work re-organisation to improve compliance with isolation precautions.

Conclusions

The introduction of visual cues in the form of signage offers a promising opportunity to make guidelines available directly at the frontline. Anecdotal evidence based on observations and interviews with HCP have shown that the current solution is superior to previous isolation signage. User-centred participatory design was a useful approach that holds potential for further improving design in healthcare settings.

Hand hygiene beliefs and behaviours about alcohol-based hand rub use: Questionnaire development, piloting and validation

BACKGROUND

Behavioural theories are crucial to the development and success of effective hand hygiene interventions. Research demonstrates that hand hygiene behaviours can also be influenced by religious and cultural beliefs. In this paper we detail the processes undertaken to develop a valid and reliable questionnaire to examine healthcare workers' beliefs and behaviours related to the use of alcoholbased hand rub (ABHR), with particular emphasis on associated religious and cultural factors.

METHODS

Using the Theory of Planned Behaviour, an existing questionnaire was modified and pilot-tested on 35 staff in the Quality Department. Cronbach's alpha values and mean inter-item correlations of the scale items were the main outcome measures. A Pearson correlation was conducted to assess for social desirability response bias.

RESULTS

The questionnaire demonstrated high content and face validity and satisfactory internal consistency in most scales, except for the religious beliefs, cultural beliefs and perceived behavioural control scales, where the inter-item correlations were 0.10, 0.13, and 0.14, respectively. There was a significant correlation between scores on the social desirability scale and the attitude scale. Partial correlation should be used to control the effect of social desirability responding when analysing data from the attitudes scale.

CONCLUSIONS

A validation process allowed the introduction and subsequent modification of religious and cultural belief scales to an existing questionnaire examining behavioural and attitudinal influences on hand hygiene using ABHR. Such processes should be considered for questionnaire development and modification when considering religious and cultural factors as drivers of behaviour.

Effectiveness of hand hygiene promotional program based on the WHO multimodal hand hygiene improvement strategy, in terms of compliance and decontamination efficacy in an indian tertiary level neonatal surgical intensive care unit

Background

The WHO Multimodal Hand Hygiene Improvement Strategy (MHHIS) has been proposed to improve the Hand Hygiene (HH) compliance of the WHO recommendations on HH.Therefore, the current study was planned in our neonatal unit with the objective of evaluating the effectiveness of a Hand Hygiene Promotional Program (HHPP) based on the WHO MHHIS, in terms of compliance and decontamination efficacy among the health-care workers (HCWs) in the unit.

Objective

The objective of the study was to evaluate the effectiveness of the WHO MHHIS on HH compliance and decontamination efficacy.

Methods

The HHPP was carried out in our neonatal surgical intensive care unit from July to August 2013. A pre-intervention phase consisted of assessment of ward infrastructure, HH knowledge and perception, determination of HH compliance and collection of hand rinse samples from the HCWs before and after handwashing. Intervention phase consisted of changing traditional to elbow-operated taps, display of posters and reminders, placement of soaps in water draining trays, autoclaved single-use paper towels for hand drying, availability of hand rubs and training sessions for health-care providers. In the post-intervention phase, all the assessments and observations of pre-intervention phase were repeated.

Results

HHPP resulted in a significant increase in overall HH compliance from 26.6% (95% confidence interval [CI] 23.9-29.3) to 65.3% (95% CI 62.4-68.2) (P < 0.001) and reduction in load of microorganisms (P = 0.013). There was a significant improvement in HH knowledge (P < 0.001), and perception surveys revealed high appreciation of each strategy component by the participants.

Conclusion

To the best of our knowledge, this is the first study about the effect of implementation of the WHO MHHIS from an Indian hospital. HHPP was found to be effective in terms of HH compliance and decontamination efficacy. Its implementation is highly recommended to promote HH in a developing country like India.

Nurses' knowledge, behaviour and compliance concerning hand hygiene in nursing homes: a cross-sectional mixed-methods study

Background

Effective hand hygiene is one of the most important measures for protecting nursing home residents from nosocomial infections. Infections with multi-resistant bacteria’s, associated with healthcare, is a known problem. The nursing home setting differs from other healthcare environments in individual and organisational factors such as knowledge, behaviour, and attitude to improve hand hygiene and it is therefore difficult to research the influential factors to improve hand hygiene. Studies have shown that increasing knowledge, behaviour and attitudes could enhance hand hygiene compliance in nursing homes. Therefore, it may be important to examine individual and organisational factors that foster improvement of these factors in hand hygiene. We aim to explore these influences of individual and organisational factors of hand hygiene in nursing home staff, with a particular focus on the function of role modelling by nursing managers.

Methods

We conducted a mixed-methods study surveying 165 nurses and interviewing 27 nursing managers from nursing homes in Germany.

Results

Most nurses and nursing managers held the knowledge of effective hand hygiene procedures. Hygiene standards and equipment were all generally available but compliance to standards also depended upon availability in the immediate work area and role modelling. Despite a general awareness of the impact of leadership on staff behaviour, not all nursing managers fully appreciated the impact of their own consistent role modelling regarding hand hygiene behaviours.

Conclusion

These results suggest that improving hand hygiene should focus on strategies that facilitate the provision of hand disinfectant materials in the immediate work area of nurses. In addition, nursing managers should be made aware of the impact of their role model function and they should implement this in daily 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.

Determinants of hand hygiene behaviour based on the Theory of Interpersonal Behaviour

Background:

Many investigations into the determinants of hand hygiene (HH) behaviour have explored only individual predictors or were designed according to arguably overly simplistic models of behaviour. Consequently, important influences on HH behaviour, including habit and emotion, are sometimes neglected. This study is the first to employ the Theory of Interpersonal Behaviour as a comprehensive model for understanding the determinants of HH behaviour.

Method:

A self-report questionnaire was conducted with staff from two large UK veterinary referral practices. Participants ( n = 75) reported their HH behaviour and responded to statements rating the importance of social norms, self-protection, patient protection, time pressures, access to equipment, habit and disgust, to their HH behaviour.

Results:

Regression analysis showed that, overall, determinants explained 46% of variance ( p < .001) in self-reported HH behaviour, with time constraints being the strongest predictor ( β = −.47, p < .001) followed by difficulty finding equipment ( β = −.21, p = .05).

Discussion:

Time constraints may be the most important influence on HH adherence among the determinants investigated. Future researchers should consider employing theoretical models to aid a more comprehensive understanding of the psychology underlying HH adherence and HH interventions.

Family Experiences and Perspectives on Infection Prevention in Pediatric Long-Term Care

PURPOSE

Residents of pediatric long-term care facilities (pLTCF) are particularly vulnerable to healthcare-associated infections. The aims of this qualitative study were to (a) explore perspectives on infection prevention among families visiting children in pLTCF and (b) identify facilitators of and barriers to optimal hand hygiene.

DESIGN AND METHODS

Semistructured, in-depth interviews with 10 family members visiting two New York City metropolitan area facilities were analyzed to identify themes.

FINDINGS

"Everyone follows the rules" and "infections are inevitable" were primary themes. Participants reported "common sense" as a facilitator and "distraction" as a major barrier to prevention practices.

CONCLUSION

Current education for visitors may be inadequate to improve infection prevention behaviors.

CLINICAL RELEVANCE

Nurse-led education strategies for infection prevention should be tested and modified for families visiting pLTCF.

"Hand hygiene perception and self-reported hand hygiene compliance among emergency medical service providers: a Danish survey"

Background

Hand hygiene (HH), a cornerstone in infection prevention and control, lacks quality in emergency medical services (EMS). HH improvement includes both individual and institutional aspects, but little is known about EMS providers’ HH perception and motivations related to HH quality. Therefore, we aimed to investigate the HH perception and assess potential factors related to self-reported HH compliance among the EMS cohort.

Methods

A cross-sectional, self-administered questionnaire consisting of 24 items (developed from the WHOs Perception Survey for Health-Care Workers) provided information on demographics, HH perceptions and self-reported HH compliance among EMS providers from Denmark.

Results

Overall, 457 questionnaires were answered (response rate 52%). Most respondents were advanced-care providers, males, had > 5 years of experience, and had received HH training < 3 years ago. HH was perceived a daily routine, and the majority rated their HH compliance rate ≥ 80%. Both infection severity and the preventive effect of HH were acknowledged. HH quality was perceived important to colleagues and patients, but not as much to managers. Access to supplies, simple instructions and having or being “a good example” were perceived most effective to improve HH compliance. Self-reported HH compliance was associated with years of experience and perceptions of HCAI’s impact on patient outcome, HH’s preventive effect, organizational priority, HH’s importance to colleagues and patients, and the effort HH requires (p ≤ 0.05).

Conclusion

Danish EMS providers acknowledged the impact of infections and the preventive effect of HH, and perceived access to HH supplies at the point of care, having or being “a good example” and simple instructions effective to improve HH compliance. Moreover, several behavioral-, normative- and control beliefs were associated with self-reported HH compliance, and thus future improvement strategies should be multimodal.

Interventions to increase hand hygiene compliance in a tertiary university hospital over a period of 5 years: An iterative process of information, training and feedback

AIMS AND OBJECTIVE

To explore whether an iterative process of information and training paired with a feedback system to observed healthcare professionals and the respective management improves hand hygiene (HH) compliance.

BACKGROUND

Healthcare-associated infections are a major risk for patient safety, and adherence to the "My five moments" (M5M) for HH varies significantly within organisations as well as within healthcare professional groups. Identified barriers in a baseline survey revealed the need of more information, training, repetitive compliance measurements and feedback to all healthcare professionals.

DESIGN

A quality improvement project using the method of direct observation of healthcare professionals in nonsurgical and surgical wards.

METHODS

Between 2013 and 2017, 6,009 healthcare professionals were informed and trained, and HH compliance measurements were performed by hygiene experts. Compliance measurement results were documented in an online tool to give an immediate feedback to observed healthcare professionals. Additionally, a report was forwarded to the management of the respective department to raise awareness. Compliance rates per year were descriptively summarised. The research and reporting methodology followed SQUIRE 2.0.

RESULTS

In total, 84 compliance measurements with 19,295 "M5M for HH" were observed in 49 wards. Overall, mean HH compliance increased from 81.9 ± 5.2% in 2013 to 94.0 ± 3.6% in 2017. Physicians' HH compliance rate improved from 69.0 ± 16.6% to 89.3 ± 6.6%, that of nurses from 86.0 ± 6.9% to 96.4 ± 3.1%, and that of others from 60.5 ± 27.9% to 83.8 ± 20.2%. All M5M for HH (#1-#5) increased over the study period (#1: +16.9%; #2: +20.5%; #3: +7.6%; #4: +5.9%; #5: +12.7%).

CONCLUSIONS

Results demonstrated that an iterative process of information, training, observation and feedback over a period of 5 years can be successful in increasing HH compliance. Positive trends were observed for HH compliance rates across all healthcare professional groups as well as for all M5M for HH.

Impact of a simulation-based training in hand hygiene with alcohol-based hand rub in emergency departments

BACKGROUND

Hand hygiene is the primary measure for reducing nosocomial infections based on 7 steps recommended by the WHO. The aim of this study was to assess the duration and the quality of hand hygiene before and after simulation-based training (SBT).

METHODS

The study took place in a University Hospital Pediatric Department among its residents and nurses. In assessment A, 10 hand-rubbing procedures per participant during a work day were scored by observers using a validated, anatomically based assessment scale. Two weeks later, all participants received a didactic course and SBT, followed 1 month later by assessment B, observation of 10 hand-rubbing procedures. Assessments were performed by 2 independent observers. Before-and-after testing was used to evaluate the demonstration of theoretical knowledge.

RESULTS

In total, 22 participants were included, for whom 438 hand hygiene procedures were assessed: 218 for assessment A and 220 for assessment B. The duration of hand rubbing increased from 31.16 seconds in assessment A to 35.75 seconds in assessment B (P=.04). In assessment A, participants averaged 6.33 steps, and in assessment B, participants averaged 6.03 steps (difference not significant). Significant improvement in scores was observed between assessments A and B, except for the dorsal side of the right hand. The wrist and interdigital areas were the least-cleaned zones. A difference between assessments A and B was observed for nail varnish (P=.003) but not for long nails or jewelry. Theoretical scores increased from 2.83 to 4.29 (scale of 0-5; P<.001).

CONCLUSION

This study revealed that an optimal number of steps were performed during hand-rubbing procedures and that SBT improved the duration and quality of hand hygiene, except for the dorsal right side. Emphasis should be placed on the specific hand areas that remained unclean after regular hand-rubbing procedures.
