Compared hand hygiene compliance among healthcare providers before and after the COVID-19 pandemic: A rapid review and meta-analysis

Trends in the hand hygiene practices using alcohol-based hand rubs in Japanese hospitals before and after the novel coronavirus pandemic: an observational study using national surveillance data

BACKGROUND

Healthcare-associated infections (HAIs) are a global concern in healthcare facilities, and hand hygiene (HH) using alcohol-based hand rubs (ABHR) is fundamentally crucial for their prevention. While previous studies report improvements in HH compliance amid the COVID-19 pandemic, the real situation in Japanese medical settings remains unclear.

METHODS

This observational study sought data from the Japanese national surveillance, focusing on ABHR use in hospitals before and after the COVID-19 pandemic. Data were retrieved from facilities certified to receive the Additional Healthcare Reimbursements for Infection Prevention and Control I. The study spanned five years (2019-2023), segmented quarterly, and employed Joinpoint regression analysis to assess the annual percentage change (APC).

RESULTS

Overall, ABHR use per patient per day significantly increased both in critical care units and general wards amid the pandemic. However, the APC in the critical care units demonstrated a downward trend from Q4 of 2021 to Q1 of 2023, and ABHR use in general wards remained below the amount of WHO recommendations.

CONCLUSION

This trend analysis highlighted recent patterns of ABHR use in Japanese hospitals by comparing pre- and post-COVID-19 periods. Although increases in ABHR use were observed over time, sustained efforts to promote HH compliance are necessary, particularly in general wards.

Antimicrobial resistance and self-reported hand hygiene awareness before and after an infection prevention and control programme: A 7-year analysis in a small animal veterinary teaching hospital

Infection prevention and control (IPC) in veterinary medicine is crucial to protect patients, owners, staff, and the public. An IPC programme is recommended for every animal hospital. The objective of this retrospective longitudinal study was to describe the changes in bacterial and multidrug-resistant (MDR) bacterial isolates and self-reported hand hygiene awareness and practices after an IPC programme to assess the long-term effect of this programme in small animal veterinary medicine. The IPC programme was implemented at our veterinary teaching hospital in April 2018, which included the establishment of an infection control task force, regular IPC lectures and poster campaigns, infrastructure improvement, and manual refinement. Laboratory-based surveillance was retrospectively conducted before and after the programme (January 2016-December 2022). Level and slope changes in bacterial isolates were evaluated using interrupted time-series analysis. Self-reported hand hygiene awareness and practices were assessed using an annual questionnaire. Additionally, hygiene product purchases during the study period were investigated. The monthly number of total and MDR bacterial isolates decreased significantly after the programme (MDR level change: -0.426; 95% confidence interval: -0.744, -0.109; P = 0.009; and MDR slope change: -0.035; 95% confidence interval: -0.058, -0.011; P = 0.003). Additionally, awareness of hand hygiene before touching animals improved after the programme. Overall self-reported hand hygiene practices improved, and hygiene product purchases significantly increased. These results suggested that the IPC programme may have long-term effects regarding reducing total and MDR bacterial isolates and improving hand hygiene awareness in veterinary medicine.

Characterization and assessment of exposure risks of healthcare personnel during the COVID-19 pandemic

Introduction

Healthcare personnel have the right to decent, healthy, and safe working conditions during COVID-19. Despite our best efforts to safeguard them against SARS-CoV-2 infection, a substantially large number of healthcare personnel fell ill and succumbed to COVID-19. This study aimed to characterize the SARS-CoV-2 exposures among healthcare personnel and determine the risk level of those events, thereby identifying and focusing on the key areas that influence workplace safety.

Materials and Methods

A pre-tested questionnaire was used to collect data from healthcare personnel on the type of exposure, place, and use of preventive measures, along with demographic and occupational data. Exposure events were categorized into low, moderate, and high-risk by using a risk categorization protocol.

Results

Doctors were primarily found to be involved in the aerosol-generating procedure, which had 94 times higher odds (95% CI: 43.9926-201.17) for high-risk exposures than other activities. In contrast, nurses were more likely to experience close-contact exposures (OR: 2.77, 95% CI: 1.44-5.33). Both critical care units and operation theaters were identified to have higher odds (OR: 2.34, 95% CI: 1.33-4.23 and OR: 2.31; 95% CI: 0.99-5.42, respectively) than the wards for high-risk exposures. Use of personal protective equipment was poor, with breaches reported in 10.2% of all exposure events. The lacunae in practice were addressed by repeated training and counseling and by ensuring the adequacy of resources in required areas.

Conclusions

The assessment was beneficial for safeguarding healthcare personnel and assuring a safer workplace during the early phase of the COVID-19 pandemic.

Factors associated with hand hygiene adherence among healthcare workers in Guatemala during the COVID-19 pandemic

BACKGROUND

Healthcare-associated infections are prevalent in low- and middle-income countries and may be reduced through proper hand hygiene (HH) adherence during patient care.

AIM

We produced and distributed alcohol-based hand rub (ABHR) to 19 public primary- and secondary-level healthcare facilities in Quetzaltenango, Guatemala, and carried out HH observations to assess healthcare workers' (HCWs) HH adherence, and to identify factors associated with this practice. HH adherence was defined as washing hands with soap and water or using ABHR.

METHODS

Observations were conducted before (2021, baseline) and after (2022, follow-up) ABHR distribution to evaluate the evolution of HH practices over time. Bivariate comparisons and mixed-effects logistic regression models were used to explore associations between HH adherence and the following independent variables: healthcare facility level, type of contact performed, timing of HH performance, occupational category of HCW and materials present (e.g., water, soap, ABHR).

FINDINGS

We observed 243 and 300 patient interactions among 67 and 82 HCWs at each time point, respectively. HH adherence was low for both observation periods (40% at baseline and 35% at follow-up). HCWs were more likely to adhere to HH during invasive contacts, after patient contact, and if the HCW was a physician.

CONCLUSION

HH adherence varied by scenario, which underscores the importance of addressing multiple determinants of behaviour change to improve adherence. This requires interventions implemented with a multi-modal approach that includes both increasing access to HH materials and infrastructure, as well as HH education and training, monitoring and feedback, reminders, and promoting a HH safety culture.

Infection prevention and control in Dutch general practices before and during the COVID-19 pandemic and its implications for pandemic preparedness and seasonal respiratory epidemics: a qualitative study on lessons learned

BACKGROUND

The COVID-19 pandemic has prompted a re-evaluation of infection prevention and control (IPC) in general practices, highlighting the need for comprehensive IPC implementation. This study aimed to evaluate healthcare workers' (HCWs) experiences and perspectives regarding IPC in general practices before and during the COVID-19 pandemic, and its implications for post-pandemic IPC implementation.

METHODS

This qualitative study involved semi-structured, in-depth interviews during two time periods: (1) prior to the COVID-19 pandemic (July 2019-February 2020), involving 14 general practitioners (GPs) and medical assistants; and (2) during the COVID-19 pandemic (July 2022-February 2023), including 22 GPs and medical assistants. Data analysis included thematic analysis that addressed multiple system levels.

RESULTS

Findings indicated a shift towards comprehensive IPC implementation and organisation during the pandemic compared to the pre-pandemic period. Since the Omicron variant, some general practices maintained a broad set of IPC measures, while others released most measures. HCWs' future expectations on post-pandemic IPC implementation varied: some anticipated reduced implementation due to the desire to return to the pre-pandemic standard, while others expected IPC to be structurally scaled up during seasonal respiratory epidemics. Main contextual challenges included patient cooperation, staff shortages (due to infection), shortages of IPC materials/equipment, and frequently changing and ambiguous guidelines. Key lessons learned were enhanced preparedness (e.g., personal protective equipment supply), and a new perspective on care organisation (e.g., digital care). Main recommendations reported by HCWs were to strengthen regional collaboration within primary care, and between primary care, public health, and secondary care.

CONCLUSION

HCWs' experiences, perspectives and recommendations provide insights to enhance preparedness for future epidemics and pandemics, and sustain IPC in general practices. For IPC improvement strategies, adopting an integrated system-based approach that encompasses actions across multiple levels and engages multiple stakeholders is recommended.

Impact of conducting hand hygiene audits during the COVID-19 pandemic in an intensive care unit at a tertiary care centre in Kerala, India

Background

The COVID-19 pandemic era had witnessed an upsurge of healthcare-associated infections (HAI) in COVID intensive care units (ICUs), which can be reduced by following proper hand hygiene (HH) practice. Performing HH auditing in COVID ICUs and providing timely feedback to the stake holders is crucial to reduce HAIs.

Methods

From July 2021 to December 2021, HH auditing was conducted in COVID ICUs. Hand hygiene (HH) complete adherence rate (HHCAR), HH partial adherence rate (HHPAR) and HH total adherence rate (HHTAR) were analysed. Profession-specific HHTAR and moment-specific HHTAR (for each WHO moment) were also calculated.

Results

HHCAR, HHPAR and HHTAR were found to be 47%, 19% and 66%, respectively. There was a significant increase in the monthly HHTAR from 62.2% to 72.2% (p<.001). The profession-specific hand-hygiene adherence rate (HHAR) was found to be highest among nurses (67%), and the moment-specific HHAR of WHO-moments 2 (90%) and 3 (94.8%) had the highest HH adherence.

Conclusions

Auditing HH and providing timely feedback significantly improved HH adherence. The greatest need now is to regularly conduct HH auditing in COVID locations of all healthcare facilities to reduce the HAI rate among the COVID-19 infected patients in ICUs.

Impact of COVID-19 on the degree of compliance with hand hygiene: a repeated cross-sectional study

Hand hygiene (HH) is the paramount measure used to prevent healthcare-associated infections. A repeated cross-sectional study was undertaken with direct observation of the degree of compliance on HH of healthcare personnel during the SARS-CoV-2 pandemic. Between, 2018-2019, 9,083 HH opportunities were considered, and 5,821 in 2020-2022. Chi squared tests were used to identify associations. The crude and adjusted odds ratios were used along with a logistic regression model for statistical analyses. Compliance on HH increased significantly (p < 0.001) from 54.5% (95% CI: 53.5, 55.5) to 70.1% (95% CI: 68.9, 71.2) during the COVID-19 pandemic. This increase was observed in four of the five key moments of HH established by the World Health Organization (WHO) (p < 0.05), except at moment 4. The factors that were significantly and independently associated with compliance were the time period considered, type of healthcare-personnel, attendance at training sessions, knowledge of HH and WHO guidelines, and availability of hand disinfectant alcoholic solution in pocket format. Highest HH compliance occurred during the COVID-19 pandemic, reflecting a positive change in healthcare-personnel's behaviour regarding HH recommendations.

Behavioural determinants shaping infection prevention and control behaviour among healthcare workers in Dutch general practices: a qualitative study reflecting on pre-, during and post-COVID-19 pandemic

BACKGROUND

Since the Coronavirus Disease 2019 (COVID-19) pandemic, awareness of infection prevention and control (IPC) has increased in primary care settings. This study aimed to examine behavioural determinants shaping IPC behaviour pre-, during, and post-pandemic among healthcare workers (HCWs) in general practices, to inform optimised IPC in primary care.

METHODS

For this qualitative study, semi-structured in-depth interviews were conducted during two study periods: (1) pre-COVID-19 pandemic: July 2019-February 2020, with 14 general practitioners (GPs) and medical assistants, and (2) during the COVID-19 pandemic: July 2022-February 2023, with 22 GPs and medical assistants. The design was informed by behaviour change theories. Data were analysed using thematic analysis.

RESULTS

Main themes were: (1) risk perception and IPC awareness, (2) attitudes towards IPC and professional responsibility, (3) decision-making process and risk considerations for IPC adherence, (4) social norm and social influence in GP practice team, and (5) environmental context and resource availability in GP practice. During the pandemic, risk perception and awareness of the importance of IPC increased compared to the pre-pandemic period. A consistent belief emerged that IPC is part of professional responsibility, while needing to be balanced with other aspects of patient care. Decision-making is dependent on the individual GP and mainly influenced by risk assessments and sustainability considerations. The social context in the practice team can reinforce IPC behaviours. GP practice building and layout, and limited IPC resource and material availability were reported as main barriers.

CONCLUSIONS

The theory-informed insights of this study can be used for targeted interventions to optimise IPC behaviour in general practices. Adopting multifaceted strategies to target the various determinants is recommended to sustain IPC, by implementing continuous education using tailored communication, integrating IPC in work routines and organisational workflows, refining existing IPC protocols by incorporating decision-making tools for HCWs, fostering a culture of IPC through knowledge-sharing and teamwork, and addressing GP practice physical environment and IPC resource barriers.

Impact of the COVID-19 pandemic on Clostridioides difficile infection in a tertiary healthcare institution in Belgium

OBJECTIVES

Clostridioides difficile infection (CDI) causes the greatest number of healthcare-associated infectious diarrhoea. CDIs are transmitted by direct and indirect patient-to-patient contact and risk increases with the use of antibiotics. Since early 2020, the COVID-19 pandemic has affected healthcare systems in many ways including substantial changes in hygiene behaviour. The aim of this study was to assess whether CDI incidence differed during the COVID-19 pandemic compared to a year before.

METHODS

All tests for suspected CDI cases were recorded for a hospital in Brussels, Belgium. The percentage of CDI-positive results and incidences (total and healthcare-associated (HA)-CDI)) for years 2019, 2020, 2021, and 2022 were calculated. Antibiotic consumption was analysed for years 2019 and 2020.

RESULTS

Since the COVID-19 pandemic struck, a significant reduction of up to 39% was observed in the number of Clostridioides difficile stool tests in our hospital. A significant decrease in the percentage of positive tests and a 50% decrease in the incidence of CDI (total and HA-CDI) was found for 2020 compared with 2019 and confirmed for years 2021 and 2022. The decrease in CDI incidence was mostly marked in haematology, nephrology, and gastroenterology units. No significant change in the use of antibiotics was found.

CONCLUSION

The global decrease in CDI incidence observed in our hospital was not associated with a change in the use of antibiotics. The control measures implemented to prevent COVID-19 transmission may explain a reduction in CDI incidence. An underdiagnosis of CDI cannot be excluded.

Hand hygiene with interventions: an observational study from a tertiary care institute over 2 years

Background

Appropriate adherence to hand hygiene (HH) practices by health care workers (HCWs) reduces the transmission of pathogens and subsequently the incidence of hospital acquired infections (HAIs), in health care settings. Strict monitoring and auditing of this simple and cost-effective intervention is very important, as it significantly contributes in reducing the HAIs.

Material and methods

A retrospective observational study, evaluating the HH audits from June 2021 till May 2023 in a tertiary health care facility in North India. HH audits were conducted in the ICUs and wards daily, by the trained infection control nurses (ICNs), using direct observation method based on World health organization (WHO) hand hygiene observational forms. HH total adherence (HHTAR), partial adherence (HHPAR) and complete adherence rate (HHCAR) were analyzed in Microsoft Excel sheet. HHTAR rates were compared among different profession, moments and the month wise trend was also observed over the period.

Results

A total of 24,740 HH opportunities were observed. The compliance rate for HHCAR, HHPAR and HHTAR were 20.3%, 41.5% and 61.4% respectively. Overall better compliance was reported from the ICUs, profession-specific compliance was highest among nurses (62.8%) and doctors (61.5%). Significant increase in adherence rate was appreciated post intervention 46.1% to 67.3%, (p value < 0.01).

Conclusions

Continuous monitoring and reinforcement with timely feedback for intervention and regular auditing is a necessity to improve and maintain the appropriate HH practices among the HCWs. Low- and middle-income countries need to focus more on this simple and promising measure to combat the increasing HAI rates.

The End of Life Accompanied by COVID-19: A Qualitative Study on Changes in Behavior and Stigmatization of the Grieving Families in Peru (Part II)

The rapid spread of SARS-CoV-2 has led to changes in every aspect of life and death. In Peru, where the longest quarantine has occurred with suboptimal results, the rituals have been turned around, impacting the relatives in multiple aspects. Here, we used a qualitative approach to analyze unresolved grief, hygiene changes, and stigma through semi-structured, online (Google Meet) interviews with 15 participants aged 20-72, who had lost family members to COVID-19. The recorded and transcribed interviews were analyzed using reflexive thematic analysis. Most participants had unresolved grief due to the blocking of funeral rituals, which could predispose them to prolonged mourning. After the loss of relatives, hygiene measures will be improved to avoid infections and new deaths in every family, while most participants felt no stigma in their milieu, since their relatives accompanied them during the funeral, supporting them from afar. It is important that interventions are implemented to prevent the progression of grief by providing mental health opportunities for the bereaved.

Impact of COVID-19 Pandemic on Healthcare-Associated Infections: A Systematic Review and Meta-Analysis

This study investigated how the Coronavirus Disease 2019 (COVID-19) pandemic has affected the rate of healthcare-associated infections (HAIs). PubMed, Scopus and Google Scholar were searched to identify potentially eligible studies published from December 2019 to September 2022. A random effect model was used to determine the changes in the rate of HAIs during the pandemic. Thirty-seven studies, mostly from the United States (n = 13), were included. Fifteen studies described how the pandemic affected the rate of CLABSIs and CAUTIs, and eight of them showed a significant increase in CLABSIs. The risk of CLABSIs and CDIs was 27% (pooled odds ratio [OR]: 0.73; confidence interval [CI]: 0.61-0.89; p < 0.001) and 20% (pooled OR: 1.20; CI: 1.10-1.31; p < 0.001) higher during the pandemic compared to before the COVID-19 pandemic period, respectively. However, the overall risk of HAIs was unaffected by the pandemic (pooled OR: 1.00; 95 CI: 0.80-1.24; p = 0.990). Furthermore, there were no significant changes in the risk of CAUTIs (pooled OR: 1.01; 95 CI: 0.88-1.16; p = 0.890), and SSIs (pooled OR: 1.27; CI: 0.91-1.76; p = 0.16) between the two periods. The COVID-19 pandemic had no effect on the overall risk of HAIs among hospitalized patients, but an increased risk of CLABSIs and CDI were observed during the pandemic. Therefore, more stringent infection control and prevention measures and prudent interventions to promote the rational use of antibiotics are warranted across all healthcare facilities to reduce the burden of HAIs.

Cetaceans as bio-indicators revealed the increased risks of triclosan exposure and associated thyroid hormone disruption during the COVID-19 pandemic

The global surge in disinfection practices from the COVID-19 response has raised concerns about the marine exposure to the hazardous ingredients in disinfectant products, including triclosan (TCS) and triclocarban (TCC). However, there are very limited studies on the response of marine TCS and TCC (TCs) loading to the COVID-19 pandemic. Here we used cetaceans as bio-indicators for a long-term retrospective analysis of TCs loading to the South China Sea (SCS) between 2004 and 2022. Hepatic TCs was 100% detected in all nine cetacean species (n = 120). Interestingly, TCS concentrations decreased in Indo-Pacific humpback dolphins (IPHD) before the pandemic from 2010 to 2017. However, after 2019, TCS concentrations in IPHD significantly increased several-fold. Similarly, post-pandemic TCS concentrations in Indo-Pacific finless porpoises (IPFP) and two fish species were significantly higher than pre-pandemic levels. There were significant relationships between thyroid hormones (THs) and TCs in IPHD and IPFP, suggesting that increased TCs may worsen the interference of THs homeostasis and nutritional conditions in cetaceans. These findings demonstrate the profound impact of the surging use of TCs-containing products from the COVID-19 response on marine ecosystems.

Impact of the coronavirus disease 2019 (COVID-19) pandemic on the adherence to hand hygiene practice in hospitals-Data from a Swiss national surveillance system

In >100,000 observations across Swiss acute-care hospitals, hand hygiene (HH) adherence significantly increased during the first coronavirus disease 2019 (COVID-19) wave. However, despite persisting COVID-19 activity, HH adherence returned to prepandemic levels over a 2-year observation period. These results indicate that training and support remains challenging.

Preventing Multidrug-Resistant Bacterial Transmission in the Intensive Care Unit with a Comprehensive Approach: A Policymaking Manual

Patients referred to intensive care units (ICU) commonly contract infections caused by multidrug-resistant (MDR) bacteria, which are typically linked to complications and high mortality. There are numerous independent factors that are associated with the transmission of these pathogens in the ICU. Preventive multilevel measures that target these factors are of great importance in order to break the chain of transmission. In this review, we aim to provide essential guidance for the development of robust prevention strategies, ultimately ensuring the safety and well-being of patients and healthcare workers in the ICU. We discuss the role of ICU personnel in cross-contamination, existing preventative measures, novel technologies, and strategies employed, along with antimicrobial surveillance and stewardship (AMSS) programs, to construct effective and thoroughly described policy recommendations. By adopting a multifaceted approach that combines targeted interventions with broader preventive strategies, healthcare facilities can create a more coherent line of defense against the spread of MDR pathogens. These recommendations are evidence-based, practical, and aligned with the needs and realities of the ICU setting. In conclusion, this comprehensive review offers a blueprint for mitigating the risk of MDR bacterial transmission in the ICU, advocating for an evidence-based, multifaceted approach.

Factors contributing to healthcare professionals' adaptive capacity with hospital standardization: a scoping review

BACKGROUND

Certain factors contribute to healthcare professionals' adaptive capacities towards risks, challenges, and changes such as attitudes, stress, motivation, cognitive capacity, group norms, and teamwork. However, there is limited evidence as to factors that contribute to healthcare professionals' adaptive capacity towards hospital standardization. This scoping review aimed to identify and map the factors contributing to healthcare professionals' adaptive capacity with hospital standardization.

METHODS

Scoping review methodology was used. We searched six academic databases to September 2021 for peer-reviewed articles in English. We also reviewed grey literature sources and the reference lists of included studies. Quantitative and qualitative studies were included if they focused on factors influencing how healthcare professionals adapted towards hospital standardization such as guidelines, procedures, and strategies linked to clinical practice. Two researchers conducted a three-stage screening process and extracted data on study characteristics, hospital standardization practices and factors contributing to healthcare professionals' adaptive capacity. Study quality was not assessed.

RESULTS

A total of 57 studies were included. Factors contributing to healthcare professionals' adaptive capacity were identified in numerous standardization practices ranging from hand hygiene and personal protective equipment to clinical guidelines or protocols on for example asthma, pneumonia, antimicrobial prophylaxis, or cancer. The factors were grouped in eight categories: (1) psychological and emotional, (2) cognitive, (3) motivational, (4) knowledge and experience, (5) professional role, (6) risk management, (7) patient and family, and (8) work relationships. This combination of individual and group/social factors decided whether healthcare professionals complied with or adapted hospital standardization efforts. Contextual factors were identified related to guideline system, cultural norms, leadership support, physical environment, time, and workload.

CONCLUSION

The literature on healthcare professionals' adaptive capacity towards hospital standardization is varied and reflect different reasons for compliance or non-compliance to rules, guidelines, and protocols. The knowledge of individual and group/social factors and the role of contextual factors should be used by hospitals to improve standardization practices through educational efforts, individualised training and motivational support. The influence of patient and family factors on healthcare professionals' adaptive capacity should be investigated.

Clean hands, safe care: how knowledge, attitude, and practice impact hand hygiene among nurses in Najran, Saudi Arabia

Introduction

Healthcare-acquired infections are infections that patients acquire while receiving treatment for a medical or surgical condition and can occur in all care facilities. Hospital-acquired infections and the spread of antimicrobial resistance can be reduced by implementing proper preventive measures, including hand hygiene.

Aim

This study aimed to assess nurses' knowledge and attitudes toward hand hygiene guidelines in Najran city, determine compliance levels, identify factors contributing to non-compliance, and provide recommendations for interventions to improve hand hygiene practices and reduce healthcare-associated infections risk.

Subject and methods

This cross-sectional study was conducted among nurses working in the selected government hospitals in Najran City, Saudi Arabia. A self-administered questionnaire was distributed among the targeted nurses using an online survey. The questionnaire includes socio-demographic characteristics such as age, gender, and marital status. The questionnaire had 25 items to measure knowledge, 10 to measure attitude, 6 to measure practices, and 4 to measure the impact of COVID-19 on hand hygiene practices.

Results

Among the 386 nurses recruited, 88.3% were females, and 25.6% were aged between 31 to 35 years old. Overall, good knowledge, positive attitude, and good practice levels were found in 42.5, 48.4, and 94%, respectively. The common factor influencing hand hygiene practice was the prevention of cross-infection (88.1%). The total knowledge score mean was 18 ± 3.4 (highest possible score: 25). The total attitude score mean was 37.5 ± 6.1 (highest possible score: 50). The total practice score mean was 26.9 ± 2.8 (highest possible score: 30). A higher score indicates higher KAP of hand hygiene. Factors associated with increased KAP were being older in age (Z = 6.446; p < 0.001), gender female (Z = 9.869; p < 0.001), being a Filipino nurse (H = 117.8; p < 0.001), working in a surgery department (H = 28.37; p < 0.001), having more than 10 years of experience (Z = 6.903; p < 0.001), living in shared accommodation (H = 87.22; p < 0.001), having associated chronic disease (Z = 4.495; p < 0.001), and receiving formal training in hand hygiene (Z = 2.381; p = 0.017). There was a positive highly statistically significant correlation between knowledge score and attitude score (r = 0.556), between knowledge score and practices score (r = 0.303), and between attitude score and practices score (r = 0.481).

Conclusion

In light of the results, we can say that the nurses' knowledge, attitude, and practice in regards to hand hygiene were deemed acceptable. We noticed that female nurses who were older and had more experience, as well as those who had received formal hand hygiene training, displayed better KAP compared to their counterparts. Moreover, we found a significant and positive correlation between the scores for knowledge, attitude, and practice. Nonetheless, additional research is necessary to establish the extent of KAP concerning hand hygiene.

Train-the-Trainers in hand hygiene facilitate the implementation of the WHO hand hygiene multimodal improvement strategy in Japan: evidence for the role of local trainers, adaptation, and sustainability

BACKGROUND

"Train-the-Trainers in hand hygiene" (TTT) is a standardized training to train infection prevention and control (IPC) practitioners with the aim to promote hand hygiene in health care according to the World Health Organization (WHO) multimodal improvement strategy. Little is known in the literature about the sustained impact of hand hygiene and IPC trainings adapted locally. The aim of this study is to describe the impact of three TTT courses conducted annually in Japan on the adoption of the WHO multimodal improvement strategy by local IPC practitioners who became a "trainer" after their first TTT participation as a "trainee".

METHODS

Three TTT courses were conducted annually from 2020 to 2022 in Japan. A team "TTT-Japan" composed of more than 20 IPC practitioners who completed their first TTT participation adapted the original TTT program to reflect the local healthcare context in Japan, and subsequently convened the 2nd and 3rd TTTs. Pre- and post-course evaluations and post-course satisfaction surveys of the course participants were conducted to assess improvement in knowledge on hand hygiene and perception towards the course, respectively. Attitude and practice surveys of the TTT-Japan trainers were conducted to assess their perception and experience in hand hygiene promotion. The Hand Hygiene Self-Assessment Framework (HHSAF), a validated tool created by WHO to monitor the capacity of hand hygiene promotion at facility level, was applied at TTT-Japan trainers' facilities to compare results before and after trainers' engagement. We applied inductive thematic analysis for qualitative analyses of open-ended survey questions of the trainers' attitude and practice surveys, and the Wilcoxon Sign Rank test for quantitive comparisons of pre- and post-data for the surveys and HHSAF.

RESULTS

158 Japanese healthcare workers participated in three TTT courses, the majority of whom (131, 82.9%) were nurses. Twenty-seven local trainers were involved in 2nd and 3rd TTTs. The scores of pre- and post-course evaluations significantly improved after the course (P < 0.001) and the improvement was consistent across all three TTTs. Post-course satisfaction survey showed that over 90% of the participants reported that the course met their expectations and that what they learned in the courses would be useful for their practice. Trainers' attitude and practice survey showed that more than three quarters (76.9%) of the trainers reported that their experience as a trainer had a positive impact on their practice at their own facilities. Qualitative analysis of the trainers' attitude and practice survey revealed that trainers appreciated continuous learning as a trainer, and group effort to promote hand hygiene as the TTT-Japan team. The HHSAF institutional climate change element at the trainers' facilities significantly improved after their engagement as a trainer (P = 0.012).

CONCLUSIONS

TTTs were successfully adapted and implemented in Japan, leading to sustained hand hygiene promotion activities by local trainers over three years. Further research is warranted to assess the long-term impact on local hand hygiene promotion in different settings.

Impact of conducting hand hygiene audit in COVID-19 care locations of India-A large scale national multicentric study - HHAC study

PURPOSE

Hand hygiene (HH), the core element in infection prevention in healthcare, especially for multidrug resistant organism's transmission. The role of HH audits and HH adherence rates in the COVID-19 pandemic, especially in resource limited settings, are yet to be established.

METHODS

A nationwide multicenter study was conducted in India, involving public, private, teaching and non-teaching COVID healthcare facilities (COVID-HCFs) using the IBhar mobile application based on WHO's hand hygiene audit tool. The HH adherence rates (HHAR) such as complete HHAR (HHCAR), total HHAR (HHTAR), profession specific HHAR, WHO's 5 HH moment specific HHAR and associated variables were measured over 6 month duration (June-December 2021).

RESULTS

A total of 2,01,829 HH opportunities were available and the HHCAR and HHTAR were 27.3% and 59.7%. The HHTAR was significantly higher in the west zone (72.2%), private institutes (65.6%), non-teaching institutes (67.7%), nurses (61.6%), HH moments 2 (71.8%) and 3 (72.1%), and morning shift (61.4%). The HHTAR was better in non-COVID HCFs (65.4%) than COVID-HCFs (57.8%) as well as non-COVID ICUs (68.1%) than COVID ICUs (58.7%). The HHTAR was increased from month 1 to month 6 except a small decrease in the month of December.

CONCLUSIONS

The hand hygiene adherence is comparable with adherence rate during COVID-19 pandemic in western countries as well as the resource limited settings. The use of gloves during the pandemic and simplified HH techniques and their influence over the HH adherence to be studied further. The sustainable adherence rate over long duration needs to be ensured by continuing the HH audit using multimodal interventions.

Cost-effectiveness analysis of a hand hygiene monitoring system in a tertiary pediatric hospital in Mexico

Background

An automated hand-hygiene monitoring system (AHHMS) was implemented in October 2019 at the Hospital Infantil de México Federico Gómez (HIMFG), a tertiary pediatric referral hospital, in four of the hospital wards with the highest rates of Healthcare Associated Infections (HAIs). The clinical and economic impact of this system had not yet been assessed prior to this study. This study aimed to evaluate if the AHHMS is a cost-effective alternative in reducing HAIs in the HIMFG.

Methodology

A full cost-effectiveness economic assessment was carried out for the hospital. The alternatives assessed were AHHMS implementation vis-a-vis AHHMS non-implementation (historical tendency). The outcomes of interest were infection rate per 1,000 patient-days and cost savings as a result of prevented infections. Infection rate data per 1,000 patient-days (PD) were obtained from the hospital's Department of Epidemiology with respect to the AHHMS. As regards historical tendency, an infection-rate model was designed for the most recent 6-year period. Infection costs were obtained from a review of available literature on the subject, and the cost of the implemented AHHMS was provided by the hospital. The assessment period was 6 months. The incremental cost-effectiveness ratio was estimated. Costs are reported in US Dollars (2021). Univariate sensitivity and threshold analysis for different parameters was conducted.

Results

The total estimated cost of the AHHMS alternative represented potential savings of $308,927–$546,795 US Dollars compared to non-implementation of the system (US$464,102 v. US$773,029–$1,010,898) for the period. AHHMS effectiveness was reflected in a diminished number of infections, 46–79 (−43.4–56.7%) compared to non-implementation (60 v. 106-139 infections).

Conclusion

The AHHMS was found to be a cost-saving alternative for the HIMFG given its cost-effectiveness and lower cost vis-a-vis the alternate option. Accordingly, the recommendation was made of extending its use to other areas in the hospital.

Preventive Measures among Healthcare Workers (HCWs) during the COVID-19 Pandemic

COVID-19, caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), placed health systems worldwide under immense pressure, and healthcare workers (HCWs) were at the front lines. The Puerto Rico Department of Health confirmed the first case of COVID-19 in March 2020. We aimed to assess whether COVID-19 preventive measures implemented by HCWs were effective in a work scenario before vaccine availability. We conducted a descriptive cross-sectional study from July to December 2020 to evaluate the use of personal protective equipment (PPE), hygiene guidelines, and other measures taken by HCWs to prevent the spread of SARS-CoV-2. We collected nasopharyngeal specimens for molecular testing at the beginning of the study and follow-up. We recruited 62 participants aged 30-59 (79% women). Participants recruited from hospitals, clinical laboratories, and private practice included medical technologists (33%), nurses (28%), respiratory therapists (2%), physicians (11%), and others (26%). Among our participants, nurses were at higher risk (p < 0.05) of infection. We identified that 87% of participants followed the hygiene recommendation guidelines. In addition, all participants practiced handwashing or disinfection before or after caring for each patient. All participants tested negative for SARS-CoV-2 during the study period. On follow-up, all study participants reported being vaccinated against COVID-19. The implementation of PPE and hygiene measures showed high efficacy as a prevention method against SARS-CoV-2 infection when vaccines and treatment were not widely available in Puerto Rico.

Health Service Management and Patient Safety in Primary Care during the COVID-19 Pandemic in Kosovo

BACKGROUND

Several changes must be made to the services to ensure patient safety and enable delivering services in environments where the danger of infection of healthcare personnel and patients in primary care (PC) institutions is elevated, i.e., during the COVID-19 pandemic.

OBJECTIVE

This study aimed to examine patient safety and healthcare service management in PHC practices in Kosovo during the COVID-19 pandemic.

METHODS

In this cross-sectional study, data were collected using a self-reported questionnaire among 77 PHC practices.

RESULTS

Our main finding reveals a safer organization of PC practices and services since the COVID-19 pandemic compared to the previous period before the pandemic. The study also shows a collaboration between PC practices in the close neighborhood and more proper human resource management due to COVID-19 suspicion or infection. Over 80% of the participating PC practices felt the need to introduce changes to the structure of their practice. Regarding infection protection measures (IPC), our study found that health professionals' practices of wearing a ring or bracelet and wearing nail polish improved during the COVID-19 pandemic compared to the pre-pandemic period. During the COVID-19 pandemic, PC practice health professionals had less time to routinely review guidelines or medical literature. Despite this, implementing triage protocols over the phone has yet to be applied at the intended level by PC practices in Kosovo.

CONCLUSIONS

Primary care practices in Kosovo responded to the COVID-19 pandemic crisis by modifying how they organize their work, implementing procedures for infection control, and enhancing patient safety.

Do task and item difficulty affect overestimation of one's hand hygiene compliance? A cross-sectional survey of physicians and nurses in surgical clinics of six hospitals in Germany

BACKGROUND

One barrier to hand hygiene compliance is overestimation of one's own performance. Overconfidence research shows that overestimation tends to be higher for difficult tasks, which suggests that the magnitude of overestimation also depends on how it is assessed. Thus, we tested the hypothesis that overestimation was stronger for hand hygiene indications with low compliance (i.e., high difficulty), and the hypothesis that self-reported overall compliance based on a single item is higher than based on "5 Moments of Hand Hygiene" (WHO-5) items, since the single item implies an aggregation across indications.

METHODS

In the WACH trial (German Clinical Trials Register [DRKS] ID: DRKS00015502), a questionnaire survey was conducted among physicians and nurses in nine surgical clinics (general/visceral surgery or orthopedics/trauma surgery) of six German hospitals. Self-reported compliance was assessed both by a single item and the WHO-5-items using percentage scales. These were compared with each other and with direct observations. Relative frequencies of the WHO-5 indications used to calculate the WHO-5-based self-reported overall compliance rate were estimated by a systematized review of the literature (see appendix). In analysis, t-tests, Chi2-tests and multiple linear regressions were used.

RESULTS

Ninety-three physicians (response rate: 28.4%) and 225 nurses (30.4%) participated. Significant compliance differences between physicians and nurses were found for direct observations and were in favor of nurses, while no such differences were found for self-reports. Across the WHO-5, overestimation showed inverse correlations with observed compliance (physicians: r = -0.88, p = 0.049; nurses: r = -0.81, p = 0.093). Support for the hypothesis that the self-reported overall compliance based on one item is higher than that based on WHO-5 items was found for physicians (M = 87.2 vs. 84.1%, p = 0.041; nurses: 84.4 vs. 85.5%, p = 0.296). Exploratory analyses showed that this effect was confined to orthopedic/trauma surgeons (89.9 vs. 81.7%, p = 0.006).

CONCLUSION

Among physicians, results indicate stronger hand hygiene overestimation for low-compliance indications, and when measurements are based on a single item versus the five WHO-5 items. For practice, results contribute to infection prevention and control's understanding of overestimation as a psychological mechanism that is relevant to professional hand hygiene.

Risk stratification for selecting empiric antibiotherapy during and after COVID-19

PURPOSE OF REVIEW

SARS-CoV-2 deeply modified the risk of bacterial infection, bacterial resistance, and antibiotic strategies. This review summarized what we have learned.

RECENT FINDINGS

During the COVID-19 pandemic, we observed an increase in healthcare-acquired infection and multidrug-resistant organism-related infection, triggered by several factors: structural factors, such as increased workload and ongoing outbreaks, underlying illnesses, invasive procedures, and treatment-induced immunosuppression. The two most frequently healthcare-acquired infections described in patients hospitalized with COVID-19 were bloodstream infection, related or not to catheters, health-acquired pneumonia (in ventilated or nonventilated patients). The most frequent species involved in bacteremia were Gram-positive cocci and Gram-negative bacilli in health-acquired pneumonia. The rate of Gram-negative bacilli is particularly high in late-onset ventilator-associated pneumonia, and the specific risk of Pseudomonas aeruginosa- related pneumonia increased when the duration of ventilation was longer than 7 days. A specificity that remains unexplained so far is the increase in enterococci bacteremia.

SUMMARY

The choice of empiric antibiotimicrobials depends on several factors such as the site of the infection, time of onset and previous length of stay, previous antibiotic therapy, and known multidrug-resistant organism colonization. Pharmacokinetics of antimicrobials could be markedly altered during SARS-CoV-2 acute respiratory failure, which should encourage to perform therapeutic drug monitoring.

Assessment of potential for viral contamination of user and environment via aerosols generated during hand drying: A pilot study

Background

Hand drying is an essential step of hand hygiene, helping remove microbes remaining on hands following handwashing. However, it is unclear whether particles dispersed or aerosolized during hand drying can also have an impact on microbe dissemination and so pose an infection risk.

Methods

We used a PR772 bacteriophage to investigate whether microorganisms remaining on hands can disperse in the washroom environment and contaminate facemasks of others sharing the same space, as a surrogate for virus inhalation risk. Hand drying using either a jet air dryer or paper towels were performed, and mask contamination by splattering and droplet deposition was investigated, up to 15 min following each procedure.

Results

Facemask contamination by splattering was 10-fold higher when a jet air dryer was used, compared with hand drying by paper towels, for both the person performing the hand drying and for standby users stationed at 1 and 2 m distance. Facemask contamination by droplet/aerosols deposition was higher in the first 5 min following hand drying, for both methods; however, virus load was significantly higher when a jet air dryer was used. In the jet air dryer assays, facemask contamination increased at 15 min post-hand drying, suggesting aerosolization of small particles that remain airborne for longer.

Conclusion

When using a jet air dryer, virus contamination dispersed further and for a longer period of time (up to 15 min post hand-drying). The method chosen for hand drying can potentially impact the airborne dissemination of microbial pathogens, including respiratory virus, and so potentially increase the risk of exposure and infection for other washroom users.

Prevalence and Health Outcomes of Clostridioides difficile Infection during the COVID-19 Pandemic in a National Sample of United States Hospital Systems

Background

The coronavirus disease 2019 (COVID-19) pandemic resulted in unprecedented emphasis on infection control procedures; however, it is unknown whether the pandemic altered Clostridioides difficile infection (CDI) prevalence. This study investigated CDI prevalence before and during the COVID-19 pandemic in a national sample of United States (US) hospitals.

Methods

This was a retrospective cohort study using the Premier Healthcare Database. Patients with laboratory-confirmed CDI from April 2019 through March 2020 (pre–COVID-19 period) and April 2020 through March 2021 (COVID-19 period) were included. CDI prevalence (CDI encounters per 10 000 total encounters) and inpatient outcomes (eg, mortality, hospital length of stay) were compared between pre–COVID-19 and COVID-19 periods using bivariable analyses or interrupted time series analysis.

Results

A total of 25 992 CDI encounters were included representing 22 130 unique CDI patients. CDI prevalence decreased from the pre–COVID-19 to COVID-19 period (12.2 per 10 000 vs 8.9 per 10 000, P < .0001), driven by a reduction in inpatient CDI prevalence (57.8 per 10 000 vs 49.4 per 10 000, P < .0001); however, the rate ratio did not significantly change over time (RR, 1.04 [95% confidence interval, .90–1.20]). From the pre–COVID-19 to COVID-19 period, CDI patients experienced higher inpatient mortality (5.5% vs 7.4%, P < .0001) and higher median encounter cost ($10 832 vs $12 862, P < .0001).

Conclusions

CDI prevalence decreased during the COVID-19 pandemic in a national US sample, though at a rate similar to prior to the pandemic. CDI patients had higher inpatient mortality and encounter costs during the pandemic.

Quantification of diurnal variation in “glove hygiene” compliance in COVID ICUs: an exploratory study

Background

Hand hygiene compliance (HHC) monitoring is almost always done in daytime. Documentation of HHC in health care workers (HCWs) is limited during odd hours and nighttime. The objective of the study was to determine diurnal variation in HHC in different categories of health care workers in tertiary care hospital in North India.

Methods

A prospective, observational study was conducted in 3 COVID-19 intensive care units (ICUs) with closed-circuit television (CCTV) cameras. Dedicated infection control nurses monitored HHC among various HCWs (doctors, nursing staff, technicians, hospital and sanitary attendants) during day and nighttime, in 20-minute durations. The difference in HHC by-professional category and for each WHO moment was assessed using χ² test and P value.

Results

A total of 705 opportunities were observed over a period of 7 days, with overall compliance of 53%. Day and nighttime compliance was recorded to be 60.7% and 42.1%, respectively (P < .001). HCC was highest amongst resident doctors with little diurnal variation. However, nurses and housekeeping staff exhibited significant diurnal variation. The compliance at “after” moments was much higher than “before” moments in all professional categories.

Conclusion

There was a significant decrease in compliance during nighttime, amongst all HCWs, with maximum variation exhibited by nursing staff. The present study underlines the importance of monitoring HHC at odd hours, to elicit a more accurate picture round the clock. Health care facilities monitoring compliance only during the daytime may substantially overestimate HHC.

The effect of compliance to Hand hygiene during COVID-19 on intestinal parasitic infection and intensity of soil transmitted helminthes, among patients attending general hospital, southern Ethiopia: Observational study

BACKGROUND

Intestinal parasitic infection (IPIs) is one of the major health problems in Sub -Saharan Africa where water, sanitation and hygiene practices are inadequate. Taking into account the national level implementation of intensive hand hygiene against COVID-19 pandemic and general protective effect this study assessed its effect on intestinal parasite.

OBJECTIVE

This study aim to investigate the effect of compliance to hand hygiene practice on the prevalence of intestinal parasitic infection (IPIs) and intensity of Soil transmitted helminthes (STH) among patients attending tertiary care hospital in southern Ethiopia.

METHODS

Observational study was conducted from June to September 2021. Data on socio demographic, hand hygiene practice and intestinal parasite (prevalence and intensity of helminthic infection) was collected from randomly selected and consented patients. Compliance to hand hygiene practice was assessed using pre-tested questionnaire. Fresh stool sample from each participant was examined by direct wet mount, concentration and Ziehl-Neelson (ZN) staining technique to detect intestinal parasite. Intensity of STH measurements was done through direct egg-count per gram using Kato Katz methods. Data analysis was done using SPSS version 25. Odds ratio with 95% confidence interval was used to measure association and p-value <0.05 was considered as statistically significant.

RESULTS

The study population (N = 264) consisted of 139(52.65%) male and 125 (47.34%) female with the mean ages of 36 ±16.12(±SD). The proportion of good compliance to hand hygiene during COVID-19 to was 43.93% (95%CI: 37% to 47) and prevalence of intestinal parasite was 26.14% (95%CI:21.2% to 31.75) comprising 23.48% intestinal protozoa and 6.43% of soil transmitted helminthic infection. Gardia lamblia, Entamoeba histolytica/dispar, Ascaris lumbricoides were the common parasite in the study area with prevalence of 15.53%, 6.44%, and 1.52% respectively. Prevalence of intestinal parasite among participants with good compliance to hand hygiene group and poor compliance to hand hygiene were (14.65% vs. 35.13%)(AOR: 0.48,95%CI:0.13 to 0.68) (p = 0.002) implying that good compliance to hand hygiene can reduce the risk of IPIs by 52%. Moreover significantly lower odds of intestinal protozoa among good compliance to hand hygiene group than the control (OR:0.38; (95%CI: 0.20 to 0.71);P = 0.001. However, no significant difference in the odds of intensity of STH infection in good compliance hand hygiene and poor compliance group. The result of this study also confirmed the association between intestinal parasitic infections and younger /adolescent age, education status, habit of eating raw vegetable and figure nail status.

CONCLUSION

Good hand hygiene compliance during COVID-19 significantly associated with reduction of intestinal parasitic infection. This finding highlights the secondary protective effect of improved hand hygiene against IPIs and suggest it can used in augmenting the existing parasitic control strategies in the study setting.

Practice and System Factors Impact on Infection Prevention and Control in General Practice during COVID-19 across 33 Countries: Results of the PRICOV Cross-Sectional Survey

Infection prevention and control (IPC) is an evidence-based approach used to reduce the risk of infection transmission within the healthcare environment. Effective IPC practices ensure safe and quality healthcare. The COVID-19 pandemic highlighted the need for enhanced IPC measures and the World Health Organization (WHO) emphasized the need for strict adherence to the basic principles of IPC. This paper aims to describe the IPC strategies implemented in general practice during the COVID-19 pandemic and to identify the factors that impact their adoption. Data were collected by means of an online self-reported questionnaire among general practices. Data from 4466 practices in 33 countries were included in the analysis. Our results showed a notable improvement in IPC during COVID-19 with more practices reporting that staff members never wore nail polish (increased from 34% to 46.2%); more practices reporting that staff never wear a ring/bracelet (increased from 16.1% to 32.3%); and more practices using a cleaning protocol (increased from 54.9% to 72.7%). Practice population size and the practice payment system were key factors related to adoption of a) range of IPC measures including patient flow arrangements and infrastructural elements. An understanding of the interplay between policy, culture, systemic supports, and behavior are necessary to obtain sustained improvement in IPC measures.

It is complicated: Potential short- and long-term impact of coronavirus disease 2019 (COVID-19) on antimicrobial resistance—An expert review

As of December 2021, the coronavirus disease 2019 (COVID-19) pandemic has claimed millions of deaths and caused disruptions in health systems around the world. The short- and long-term effects of COVID-19 on antimicrobial resistance (AMR), which was already a global threat before the pandemic, are manifold and complex. In this expert review, we summarize how COVID-19 might be affecting AMR in the short term (by influencing the key determinants antibiotic use, infection control practices and international/local mobility) and which additional factors might play a role in the long term. Whereas reduced outpatient antibiotic use in high-income countries, increased awareness for hand hygiene, and reduced mobility have likely mitigated the emergence and spread of AMR in the short term, factors such as overuse of antibiotics in COVID-19 patients, shortage of personal protective equipment, lack of qualified healthcare staff, and patient overcrowding have presumably facilitated its propagation. Unsurprisingly, international and national AMR surveillance data for 2020 show ambiguous trends. Although disruptions in antibiotic stewardship programs, AMR surveillance and research might promote the spread of AMR, other developments could prove beneficial to the cause in the long term. These factors include the increased public awareness for infectious diseases and infection control issues, the strengthening of the One Health perspective as outlined by the Centers for Disease Control and Prevention, and the unprecedented number of international research collaborations and platforms. These factors could even serve as leverage and provide opportunities to better combat AMR in the future.
