Healthcare-associated infection management in 62 ICUs for patients with congenital heart disease in China: a survey study.

All patients with congenital heart disease (CHD) receive postoperative management in ICUs. Infection prevention and control (IPC) has a significant impact on prognosis. This study provides a preliminary understanding of the fundamental aspects of IPC in ICUs following CHD surgery in China. From September to October 2023, we initiated a survey on healthcare-associated infection (HAI) management in hospitals that perform CHD surgeries independently. The questionnaires were jointly completed by the ICU physicians and IPC personnel. Duplicate or unqualified questionnaires were excluded from the study. The contents of our questionnaires covered hospital and ICU capacity, performance of the infection control department, HAI surveillance, implementation of IPC measures, and antimicrobial stewardship (AMS). Qualified questionnaires were compared according to the volume of annual CHD surgeries performed in different ICUs. Group 1 was defined as volume more than 300 cases and group 2 was defined as volume less than or equal to 300 cases. Sixty-two of the 118 questionnaires were completed, with a response rate of 53%. The CHD surgical volume in 2022 of the 62 hospitals was 36342, accounting for 52% of the annual CHD surgical volume (69672) across the country. The postoperative infection rates obtained from the 15 ICUs varied from 1.3 to 15%, with a median rate of 4.5%. A total of 16 ICUs provided data on drug-resistant bacteria, Klebsiella pneumoniae exhibiting the highest frequency. More than 95% of ICUs have established complete HAI management systems. Information-based HAI surveillance was conducted in 89% of ICUs. Approximately 67% of ICUs stopped prophylactic antibiotics within 48 hours after surgery. In complex cases, carbapenems were administered empirically in 89% of ICUs. Group 1 had an advantage over group 2 in preventing multi-drug-resistant organisms (all instruments should be used alone 100% vs. 86%, P =0.047; cleaning and disinfection of environmental surfaces, 100% vs. 81%, P =0.035; antibiotic consumption control 85% vs. 61%, P =0.044) and in preventing surgical site infections (perioperative blood glucose monitoring, 88% vs. 67%, P =0.048). However, Group 1 did not perform well in preventing catheter-related bloodstream infection (delayed catheter removal due to convenience of laboratory tests, 31% vs. 6%, P =0.021) and catheter-associated urinary tract infection (delayed catheter removal due to muscle relaxant administration, 88% vs. 58%, P =0.022). A relatively complete HAI management system has been established throughout the country in ICUs for CHD patients. Information-based surveillance of HAI needs to be promoted, and actions should be taken to facilitate the implementation of IPC measures and AMS bundles. Training and feedback are critical for implementing IPC measures.

Assessment of Infection Control Practices among Healthcare Workers Working at Tertiary Care Hospital of Larkana, Sindh: A Cross Sectional Survey

Background: The increasing prevalence of healthcare-associated infections (HCAIs) represents a significant challenge to patient safety worldwide, particularly in tertiary care settings where the risk of transmission is heightened. Effective infection prevention and control (IPC) practices, including hand hygiene, are pivotal in mitigating these risks. Despite the critical importance of these measures, adherence varies significantly across different healthcare settings, especially in low and middle-income countries. Objective: This study aims to assess the knowledge, attitudes, and self-reported practices related to infection control among healthcare workers in a tertiary care hospital in Larkana, with a specific focus on hand hygiene practices. The study seeks to identify gaps in knowledge and practice that could be targeted to improve overall IPC measures within the hospital. Methods: A cross-sectional survey was conducted among healthcare workers at a tertiary care hospital in Larkana, utilizing a WHO-validated self-administered questionnaire. The survey covered various aspects of IPC, including hand hygiene knowledge, attitudes towards infection control, and self-reported adherence to IPC practices. The participants included doctors, nurses, paramedics, pharmacists, and technicians, with data collected on demographic details, professional roles, and specific IPC practices. Results: Out of 317 respondents, a substantial proportion, 65.93% (209 participants), reported routinely using alcohol-based hand rubs, indicating good practice adherence. Furthermore, 88.32% (280 participants) demonstrated sufficient knowledge on the correct handwashing technique as recommended by the WHO. Comparative analysis within the professional groups revealed that doctors and technicians were more likely to report higher adherence to hand hygiene practices than other healthcare workers. Conclusion: The study underscores a generally high level of knowledge and adherence to hand hygiene practices among healthcare workers in the surveyed tertiary care hospital in Larkana. Despite these positive findings, the variability in self-reported practices across different professional groups suggests the need for targeted educational and policy interventions to ensure uniform IPC compliance.

From COVID-19 Reflections: Crucial Strategies for Ensuring Healthcare Worker and Patient Safety in Developing Countries

Globally, as millions of individuals stopovered at home to curtail the spread of COVID 19, healthcare workers (HCWs) remained in field to save mankind from the deadly virus. They attended the hospitals as well as clinics, exposed themselves to risk of COVID 19. Despite multiple steps taken by global health agencies, about 704,301,493 individuals were infected and 7,006,979 died around the globe. A significant proportion of transmissions was reported from health care settings among the health care workforce and patients. About 20% of the health care workforce of Italy was infected and many died in that outbreak, along with significant ratio of disease transmission to thir families. Physical and mental health of HCWs were affected badly because of the nuisance of hard triage verdicts and expiry of patients and colleagues. The frequency of HCWs who have acquired COVID 19 was high among the endemic countries. The key causative factors for the healthcare-associated COVID 19 spreads included lack of personal protective equipment availability, improper use of PPEs, lack of training of HCWs, overcrowding in hospitals and lack of proper acquiescence to and acceptance of the significance of fulfilling infection prevention and control (IPC) strategies. This credence was reinforced by globally renowned agencies i.e., WHO and the CDC. The agencies facilitated and implemented adopting IPC measures

A168 RATES OF CLOSTRIDIOIDES DIFFICILE INFECTIONS REQUIRING HOSPITALIZATION DURING THE COVID-19 PANDEMIC

Abstract Background Clostridium difficile infection (CDI) is the most common cause of nosocomial infectious diarrhea and is associated with a substantial burden of morbidity and mortality. Most cases of CDI are acquired through health care setting contacts, where appropriate infection prevention and control (IPC) measures such as contact isolation and proper hand hygiene have been demonstrated to prevent horizontal transmission. Aims We aimed to evaluate whether there was a reduction in CDI-related hospitalizations during the COVID-19 pandemic when an increased emphasis was placed on maintaining IPC measures. Methods We analyzed data from the National Inpatient Sample (NIS) between January 2018 and November 2020. The NIS is the largest publicly available administrative health database in the United States, capturing ampersand:003E7 million hospital admissions annually. All analyses were weighted for the complex survey design of the NIS. Temporal trends in monthly admissions for patients with CDI defined using International Classification of Disease 10th revision codes and excluding patients with established CDI carrier status were evaluated using joinpoint regression. Changes over time were expressed as monthly percent change (MPC). To establish whether temporal changes were related to a reduction in CDI or whether these were more generalized effects due to the pandemic, we compared these temporal trends to rates of hospitalizations for inflammatory bowel disease (IBD) and stroke. Results A total of 1,501,415 CDI admissions were identified. The mean age was 64.6 years and 54.2% of patient’s were female. 4.5% of admissions for CDI were associated with in-hospital mortality. Trends in hospitalization are summarized in Figure 1. Compared to the pre-pandemic period (January 2018-December 2019) CDI-related hospitalizations decreased by 9.1%/month [95% CI: -19.2%, +2.0%] (p=0.12) in early 2020 (January-March 2020). This reduction was not sustained: hospitalizations subsequently increased by +8.0% [95% CI: -4.0%, +21.6%] (p=0.19) in mid-2020 (April-June 2020) and were stable after July 2020 (MPC -0.9% [95% CI: -3.5%, +1.7%], p=0.48). Similar patterns were observed for both IBD and stroke-related hospitalizations. Total hospitalizations per month for CDI were similar by June 2020 as compared to the year preceding the pandemic. Conclusions Although an initial decrease in the rates of CDI hospitalizations were seen early in the pandemic (January-March 2020), this pattern was similarly seen for other chronic and acute conditions, and this has not been sustained long-term.

High seroprevalence of severe acute respiratory syndrome coronavirus 2 among healthcare workers in Yaoundé, Cameroon after the first wave of Covid-19 pandemic and associated factors.

Healthcare workers (HWs) are at a high risk of exposure to emerging health threats. Following the first wave of the coronavirus disease 2019 pandemic in Cameroon, we explored the presence and persistence of naturally acquired antibodies against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and the factors associated with seropositivity in HWs. Staff at two referral hospitals in Yaoundé or two Health District Hospitals in Obala and Mbalmayo were included in a 6-month prospective cohort analysis or cross-sectional survey, respectively. Seroprevalence and associated factors were determined, and Kaplan-Meier curves and Cox proportional hazards models were used to assess antibody persistence or positive seroconversion over time. From August 2020 to March 2021, 426 HWs (median age: 31 years, interquartile range: 27-37 years; 66.4% female) were enrolled. The overall seroprevalence of anti-SARS-CoV-2 antibodies was 54.0% (95% confidence interval [CI]: 49.1-58.8) and was significantly different between study sites (p = 0.04). Of the 216 HWs included in the 6-month cohort, 109 (50.5%) HWs were seropositive at inclusion; the probability of persistent antibodies or of becoming seropositive was 93.8% (95% CI: 84.2-100) and 78.9% (95% CI: 61.7-88.4), respectively. Seroconversion was associated with study site and occupation but not with infection prevention and control (IPC) practices. We observed high seroprevalence of SARS-CoV-2 antibody and seroconversion among HWs associated with occupational risk. This suggests low compliance to the COVID-19 control measures. Continued training and implementation of IPC measures and accelerated preparedness are needed to better tackle future threats.

Staphylococcal aureus outbreaks in neonatal intensive care units: strategies, nuances, and lessons learned from the frontline.

Methicillin-resistant Staphylococcus aureus (MRSA) infections in neonates can result in significant morbidity and mortality. However, comparatively to adults, neonatal MRSA data remains relatively scarce. Additionally, while evidence-driven practices for adults have seen considerable progress, neonatal infection prevention strategies remain poorly described. The Leeds Newborn Service adopted a series of infection prevention and control (IPC) measures following a rise in MRSA cases in 2008-2009. This narrative review presents IPC measures for neonatal MRSA and methicillin-sensitive Staphylococcus aureus (MSSA) infections and reflects upon local challenges and successes of these interventions. Our experience underscores the importance of an adaptive, evidence-based strategy, tailored to the neonatal population. Effectively addressing MRSA/MSSA requires continuous monitoring with sustained targeted interventions. Our key learning points highlight the intertwined difficulties of specific neonatal requirements and lack of definitive IPC guidance, suggesting a holistic approach is key for successful IPC outcomes in the neonatal intensive care unit setting.

Importance of Hospital Infection Control.

The increasing demand for healthcare-acquired infection (HAI) control practices and services has intensified the need to evaluate care quality. The World Health Organization (WHO) introduced an infection prevention and control (IPC) framework to mitigate the impact of HAIs, crucial for ensuring patient safety in hospitals. HAIs acquired after hospitalization pose significant challenges due to factors such as compromised immunity, invasive medical procedures, and antibiotic-resistant pathogens, which have dire consequences, including higher mortality rates and increased healthcare costs. Healthcare workers (HCWs) are critical in implementing IPC measures. Infection control programs that include strategies such as hand hygiene, personal protective equipment (PPE), environmental cleaning, and surveillance have become standard. However, challenges such as resistance to change, resource limitations, patient turnover, and variability in patient conditions persist. Strategies to maintain hospital infection control involve rigorous compliance monitoring, staff education, advanced technologies such as artificial intelligence (AI), machine learning (ML), telemedicine, and innovative sanitation methods. The future of hospital infection control may involve increased integration of environmental monitoring, antimicrobial stewardship, and patient participation while leveraging collaboration among healthcare facilities. The review highlights the criticality of hospital infection control and suggests trends and opportunities to strengthen prevention efforts and patient safety.

Risks and challenges in COVID-19 infection prevention and control in a hospital setting: Perspectives of healthcare workers in Thailand.

In hospital settings, awareness of, and responsiveness to, COVID-19 are crucial to reducing the risk of transmission among healthcare workers and protecting them from infection. Healthcare professionals can offer insights into the practicalities of infection prevention and control (IPC) measures and on how the guideline aimed to ensure adherence to IPC, including use of personal protective equipment (PPE), could best be delivered during the pandemic. To inform future development of such guideline, this study examined the perspectives of healthcare professionals working in a large hospital during the pandemic regarding their infection risks, the barriers or facilitators to implementing their tasks and the IPC measures to protect their safety and health and of their patients. In-depth interviews were conducted with 23 hospital staff coming into contact with possible or confirmed cases of COVID-19, or were at potential risk of contracting the disease, including medical doctors, nurses, virology laboratory staff, and non-medical workers. This qualitative study was carried out as part of a knowledge, attitudes and practice survey to prevent COVID-19 transmission at Ramathibodi Hospital in Thailand. We used content analysis to categorize and code transcribed interview data. Existing IPC guideline and evidence synthesis of organisational, environmental, and individual factors to IPC adherence among healthcare workers were used to guide the development of the interview questions and analysis. Factors identified as influencing the use of, and adherence to, prevention measures among healthcare workers included knowledge, perceived risk and concerns about the infection. The extent to which these factors were influential varied based on the medical procedures, among other features, that individuals were assigned to perform in the hospital setting. Beyond availability of PPE and physical safety, ease of and readiness to utilize the equipment and implement IPC measures were crucial to motivate hospital staff to follow the practice guideline. Having a ventilated outdoor space for screening and testing, and interaction through mobile technology, facilitated the performance of healthcare workers while reducing the transmission risk for staff and patients. Adequate training, demonstration of guided practices, and streamlined communications are crucial organisational and management support factors to encourage appropriate use of, and adherence to, implementation of infection prevention and control measures among healthcare workers. This finding could help inform the development of recommendations to optimise compliance with appropriate use of these measures, and to improve guidance to reduce HCW's risk of disease in hospital settings. Further study should explore the perceptions and experiences of health professionals in smaller health facilities and community-based workers during the pandemic, particularly in resource-limited settings.

Effectiveness of inspector mechanism for the emergency infection prevention and control in the SARS-CoV-2 epidemic period: a self-control real-word study

BackgroundTo ensure emergency infection prevention and control (IPC) can be fully supervised and monitored in coronavirus disease (COVID-19) epidemic period, a three-level inspector mechanism called "Internal self-check, Departmental cross-check, and Verification of outstanding key and difficult issues" was established in southwest China. The present study aimed to explore the effectiveness of inspector mechanism for the emergency IPC.MethodsA self-control real-world study was conducted during COVID-19 epidemic period from 2020 to 2022. An innovative designed mobile phone application was used to realize paperless information transmission and data management. Data were compared between inspection levels using SPSS 19.0 software.ResultsA total of 2,800,132 supervision records were collected, including 149,137 comprehensive epidemic IPC projects, 1,410,093 personal protective equipment (PPE) use, 1,223,595 wearing and removing process of PPE and 17,307 ultraviolet light-detectable fluorescent (UV/F) surface marker. During the study period, the inspectors and subjects explored many optimized IPC measures. The compliance rate of check items has exceeded 98%, and internal self-check has a statistically significant higher rate than departmental cross-check (99.95% versus 98.74%, χ2 = 26111.479, P < 0.001). Compare with the failure rate in internal self check, the failure rate of PPE usage and wearing/removing process was statistically higher in departmental cross-check (χ2 = 1957.987, P < 0.001, χ2 = 465.610, P < 0.001, respectively). The overall clearance rate of UV/F surface markers is 87.88%, but there is no statistically significant difference over the three years of the present study (F = 2.902, P = 0.071).ConclusionsInspector mechanism for the emergency IPC completed an incredible inspection workload and offered creative assistance to combat the COVID-19 outbreak. These methods and accumulated experiences should be helpful for us to strengthen IPC for future epidemic.

An outbreak within an outbreak: The impact of Infection Prevention and Control strategies on hospital-acquired infections and the occurrence of multi-drug resistant organisms during the COVID-19 pandemic

Background. The coronavirus disease 2019 (COVID-19) pandemic placed an unprecedented strain on intensive care units (ICUs) in South Africa. Infection prevention and control (IPC) strategies were highlighted to minimise the risk to healthcare workers and for the protection of patients from contracting hospital-acquired infections (HAIs). During the third wave, our institution adopted a shift system to address severe burnout among ICU personnel. We noted an upstroke in the occurrence of HAIs, specifically carbapenem-resistant Enterobacterales (CRE) and multidrug-resistant (MDR) Acinetobacter baumannii. Objectives. To report these outbreaks, compare the rate of CRE and A. baumannii infections with the first COVID-19 wave and to analyse its impact on patient outcomes. Method. We retrospectively analysed data from a prospectively collected registry involving all adult patients with severe COVID-19 admitted to the dedicated COVID-19 ICU from May 2021 to September 2021. Information from the admission database, including the patients’ demographics, comorbidities, laboratory results and length of ICU stay were extracted. Results. Ninety patients were admitted with severe COVID-19 during the third wave. There was an outbreak of both CRE (the majority Klebsiella pneumoniae) and A. baumannii. Furthermore, 18 patients cultured the same CRE organism, and 25 patients cultured the environmental organism A. baumannii. The HAI rate was significantly higher compared with the first wave published data: 59/90 (65.6%) v. 73/363 (20.1%, p&lt;0.01). Patients with any HAI had a longer mean stay in ICU (10.1 days v. 6.7 days (p&lt;0.01) and a higher mortality of 48/59 (81%) v. 19/31 (61%) (p=0.05). Conclusion. We observed a very significant rise in HAIs in the COVID-19 ICU during the third wave compared with the first, with almost three times as many patients developing HAIs. Unsurprisingly, it was associated with a longer mean stay in ICU and a higher mortality. The outbreak of both CRE and A. baumannii, and the fact that many patients cultured the same CRE organism and A. baumannii, strongly suggests that a critical breakdown in IPC measures had occurred.

Analysing the implementation of infection prevention and control measures in health care facilities during the COVID-19 pandemic in the African Region

BackgroundThe declaration of SARS-CoV-2 as a public health emergency of international concern in January 2020 prompted the need to strengthen infection prevention and control (IPC) capacities within health care facilities (HCF). IPC guidelines, with standard and transmission-based precautions to be put in place to prevent the spread of SARS-CoV-2 at these HCFs were developed. Based on these IPC guidelines, a rapid assessment scorecard tool, with 14 components, to enhance assessment and improvement of IPC measures at HCFs was developed. This study assessed the level of implementation of the IPC measures in HCFs across the African Region during the COVID-19 pandemic.MethodAn observational study was conducted from April 2020 to November 2022 in 17 countries in the African Region to monitor the progress made in implementing IPC standard and transmission-based precautions in primary-, secondary- and tertiary-level HCFs. A total of 5168 primary, secondary and tertiary HCFs were assessed. The HCFs were assessed and scored each component of the tool. Statistical analyses were done using R (version 4.2.0).ResultsA total of 11 564 assessments were conducted in 5153 HCFs, giving an average of 2.2 assessments per HCF. The baseline median score for the facility assessments was 60.2%. Tertiary HCFs and those dedicated to COVID-19 patients had the highest IPC scores. Tertiary-level HCFs had a median score of 70%, secondary-level HCFs 62.3% and primary-level HCFs 56.8%. HCFs dedicated to COVID-19 patients had the highest scores, with a median of 68.2%, followed by the mixed facilities that attended to both COVID-19 and non-COVID-19 patients, with 64.84%. On the components, there was a strong correlation between high IPC assessment scores and the presence of IPC focal points in HCFs, the availability of IPC guidelines in HCFs and HCFs that had all their health workers trained in basic IPC.ConclusionIn conclusion, a functional IPC programme with a dedicated focal person is a prerequisite for implementing improved IPC measures at the HCF level. In the absence of an epidemic, the general IPC standards in HCFs are low, as evidenced by the low scores in the non-COVID-19 treatment centres.

Intrahospital transmission and infection control of Candida auris originating from a severely infected COVID-19 patient transferred abroad

Intrahospital spread of Candida auris, which survives tenaciously in many environments, can cause sustained colonization and infection. A large outbreak of C.auris was experienced in the intensive care units (ICUs) at the study hospital during the coronavirus disease 2019 (COVID-19) pandemic. The index patient with severe COVID-19, who was transferred from Vietnam in January 2022, developed C.auris candidaemia 10 days after hospitalization. From mid-June 2022 to January 2023, strengthened infection prevention and control (IPC) measures were implemented in three ICUs: (1) contact precautions and isolation (CPI) for C.auris-positive cases; (2) surveillance cultures including point-prevalence (N=718) for patients or close contacts or ICU-resident healthcare workers (HCWs); (3) intensive environmental disinfection with 10-fold diluted bleach; and (4) 2% chlorhexidine bathing for all ICU patients. Environmental cultures (ECx) on surfaces and shared objects (N=276) were conducted until early September 2022, when all ECx were negative. Among 53 C.auris-positive patients between February 2022 and January 2023, invasive infections resulted in seven cases of candidaemia and one case of pneumonia. C.auris was isolated from reusable tympanic thermometers (TTMs) contaminated with earwax. The isolation rate of C.auris in ECx decreased from 6.8% in June 2022 to 2.0% in August 2022, and was no longer detected in TTMs. Colonization in HCWs was remarkably rare (0.5%). The number of C.auris-positive patients peaked in July (N=10) then decreased gradually. By January 2023, no C.auris were isolated in the ICU. Aggressive IPC measures with CPI, ECx and surveillance, decontamination of TTMs, and bathing were effective in successfully controlling this C.auris outbreak.

Factors associated with compliance with Infection Prevention and Control measures during the COVID-19 pandemic among healthcare workers in Kampala City, Uganda.

In the context of the COVID-19 pandemic that originated from China in December 2019 and spread around the world, Kampala City witnessed a high number of infections and deaths among healthcare workers (HCWs). This study assessed the level of compliance with Infection Prevention and Control (IPC) measures and its associated factors among HCWs during the COVID-19 pandemic, in Kampala City, Uganda. A cross-sectional study was conducted in Nakawa Division, Kampala City, among 240 HCWs and used multistage sampling in government and private not-for-profit (PNFP) healthcare facilities. The outcome variable was self-reported IPC compliance which was composed of the use of masks, gloves, and hand hygiene. These were assessed using a 4-scale tool: always as recommended, most of the time, occasionally, and rarely. Only HCWs who responded "always as recommended" were considered compliant while the rest were considered non-compliant. Data was analyzed in STATA 14.0 using Modified Poisson regression to obtain factors associated with IPC compliance at 95% confidence interval (CI). Forty-six (19.2%) respondents were compliant with all the three IPC measures, and this was associated with the presence of a COVID-19 patients' ward in the healthcare facility (Adjusted Prevalence Ratio, APR: 2.51, 95%CI: 1.24-5.07). Factors associated with the use of masks were being of the Muslim religion (APR: 1.31, CI: 1.05-1.65), and working in a healthcare facility that has COVID-19 patients' ward (APR: 1.29, CI: 1.06-1.59). Factors associated with the use of gloves were the age of the HCW, those above 40 years old being less complaint (APR: 0.47, CI: 0.24-0.93), working in the diagnosis department (APR: 2.08, CI: 1.17-3.70), and working in a healthcare facility that has COVID-19 patients' ward (APR: 1.73, CI: 1.13-2.64). Factors associated with hand hygiene were working in a health center (HC) IV (PR: 1.7, CI: 1.26-2.30) or a HC II (PR: 1.68, CI: 1.28-2.21). Considering the elevated risk of disease transmission in health settings, IPC compliance was low; indicating an increased risk of COVID-19 infection among health care workers in Kampala City.

Adherence with infection prevention and control measures among Italian healthcare workers: Lessons from the COVID-19 pandemic to tackle future ones

BackgroundTo tackle future health threats, the study aimed to assess healthcare workers’ (HCWs) adherence to infection prevention and control (IPC) measures and to evaluate whether knowledge and concerns related to COVID-19 could be its potential predictors. A secondary aim was to explore how and how much healthcare facilities support HCWs to implement IPC practices. MethodsThis cross-sectional study was conducted between June and September 2021 in Southern Italy using a self-administered questionnaire. Socio-demographic and professional characteristics, COVID-19 preparedness and response plan in the facilities, knowledge about COVID-19’s transmission and non-pharmaceutical interventions (NPIs), concerns about the possibility of transmitting COVID-19 to family members and patients, adherence to IPC practices, and sources of information were investigated. ResultsAmong the 492 enrolled HCWs, the overall knowledge median score was 6 out of a maximum score of 8 and predictors of good knowledge were practicing in a facility that organized training courses about IPC measures and having more years in practice. HCWs were more concerned about the possibility of transmitting the infection to their family members (64.4%) than to negative patients (38.9%). A sizable proportion claimed to take off the face mask by touching only the straps or ties (76.3%) and to replace the face mask when it was wet (70.7%). Only 26.2% never/rarely touched the face mask while wearing it. Good adherence to preventative practices was more likely in HCWs other than physicians and practicing in a facility that organized training courses about IPC measures and in regional hospitals compared with those practicing in district hospitals. ConclusionsThe study findings produce information about what worked well and where gaps were identified during COVID-19 pandemic, along with data useful for hospitals and health systems in general to better prepare and put in place appropriate interventions in case of similar future events.

Management and control of an outbreak of NDM-producing Klebsiella pneumoniae in a teaching hospital

Abstract Background Outbreaks caused by New Delhi metallo-β-lactamase (NDM)-producing Enterobacteriaceae are a major public health threat. We report an outbreak caused by NDM-producing Klebsiella pneumoniae (KP) in an Italian teaching hospital and describe the composite management approach that led to a successful containment. Methods On August 12 2022, a 39-year old Ukrainian patient with known colonization (rectal swab) by NDM-producing KP was admitted to the Hematology Unit of the University Hospital of Verona, Italy. Six days after, a second patient tested positive for carbapenem-resistant (CR) KP from rectal swab and 2 additional cases (rectal and pharyngeal swab respectively) were identified in the following 2 weeks. The 4 cases were identical strains. Results A multidisciplinary team coordinated the response actions. Isolation measures were ordered for positive patients, including use of dedicated instruments. Screening at admission and every 7 days was placed for all the ward patients. On-site inspections and microbiological screening of ward surfaces and devices were carried out. Infection prevention and control (IPC) measures were strengthened among personnel. Environmental cleaning was implemented by deep treatment of critical points (e.g. toilets) and reinforcement of routine cleaning. The Risk Manager developed an original checklist based on literature to review the implementation of IPC practices for CR Enterobacteriaceae. No new cases were identified from screening in the following weeks and the Unit returned to standard IPC measures. Given that environmental samples were negative and the cases had overlapping personnel, the hypothesis of contact transmission through caregivers was the most plausible. Reinforcement of training on hand hygiene and transmission-based precautions was planned. Conclusions It was possible to contain the hospital outbreak through rapid and diversified reaction capacity. Continuous IPC education is an essential control measure. Key messages • The spread of NDM-producing Enterobacteriaceae in the hospital setting must be countered with enhanced prevention and, in case of outbreak, rapid control. • Effective containment involves a mix of established measures (screening, hygiene, environmental controls) and innovative approaches (e.g. literature-based checklists).

The impact of the COVID-19 pandemic on hospital-acquired infections at a comprehensive cancer center

Robust infection prevention and control (IPC) measures were deployed across health care institutions at the start of the COVID-19 pandemic, resulting in increased use of personal protective equipment, enhanced contact precautions, and an emphasis on hand hygiene. Here, we evaluate the effect of enhanced IPC practices on the occurrence of various hospital-associated infections (HAIs) in a comprehensive cancer center. From September 2016 through March 2022, we calculated the incidence rates (IRs) of HAIs for C. difficile infection, multidrug-resistant organisms, respiratory viral infections (RVIs), and device-related infections. We analyzed the incidence rate ratios for all HAIs during the periods before the pandemic, during the pandemic, atthe time of the surges, and in COVID-19-designated wards. When comparing the prepandemic to the pandemic period, the IR across all MRDOs was similar. We observed a decrease in the IR of central line-associated bloodstream infections and a stable IR of catheter-associated urinary tract infections. A significant decrease was observed in the IR of C. difficile infection. The total IR of nosocomial RVIs decreased, as did for each respiratory virus. A similar IR of nosocomial RVIs between COVID-19 community surge versus nonsurge periods was observed except for SARS-CoV-2, RSV, and influenza. multidrug resistant organisms were 5 times more likely to occur on the COVID-19 wards compared with the non-COVID-19 wards. Implementing strict IPC measures during the COVID-19 pandemic in a cancer hospital led to a significant decrease in many HAIs and a reduction in nosocomial RVIs.

Methicillin-resistant Staphylococcus aureus (MRSA) clusters in neonatal intensive care units (NICUs) and other neonatal units in New York State (NYS), 2001 to 2017

New York State (NYS) mandates reporting of all hospital-associated communicable disease outbreaks. We describe trends in NYS surveillance for neonatal unit methicillin-resistant Staphylococcus aureus (MRSA) outbreaks, the evolution of national MRSA infection prevention and control (IPC) recommendations, and IPC measures taken by NYS neonatal units. We evaluated trends of reported neonatal unit MRSA outbreaks by etiology from 2001 to 2017. We reviewed all reports and the use of IPC recommendations over time. From 2001 to 2017, 124 MRSA outbreaks were reported in 47 hospital neonatal units, with a total of 1,055 laboratory-confirmed infant cases, 18 infant deaths, and 52 laboratory-confirmed staff cases. The number of outbreaks increased with the level of care. During the study period, a higher proportion of hospitals reported implementing IPC measures, including reinforcing hand hygiene compliance (increased from 79.2% to 95.1%) and enhancing environmental cleaning and disinfection (increased from 4.2% to 78.0%) as well as performing active surveillance testing (AST) on exposed neonates (increased from 4.2% to 51.2%) and molecular testing on MRSA-positive isolates (increased from 5.3% to 18.9%). From 2001 to 2017, IPC measures in neonatal units increased in parallel with expanded national IPC recommendations. However, MRSA outbreaks in neonatal units continued to be frequent occurrences in NYS.

The incidence of nosocomial bloodstream infection and urinary tract infection in Australian hospitals before and during the COVID-19 pandemic: an interrupted time series study

BackgroundThe COVID-19 pandemic has had a significant impact on healthcare including increased awareness of infection prevention and control (IPC). The aim of this study was to explore if the heightened awareness of IPC measures implemented in response to the pandemic influenced the rates of healthcare associated infections (HAI) using positive bloodstream and urine cultures as a proxy measure.MethodsA 3 year retrospective review of laboratory data from 5 hospitals (4 acute public, 1 private) from two states in Australia was undertaken. Monthly positive bloodstream culture data and urinary culture data were collected from January 2017 to March 2021. Occupied bed days (OBDs) were used to generate monthly HAI incidence per 10,000 OBDs. An interrupted time series analysis was undertaken to compare incidence pre and post February 2020 (the pre COVID-19 cohort and the COVID-19 cohort respectively). A HAI was assumed if positive cultures were obtained 48 h after admission and met other criteria.ResultsA total of 1,988 bloodstream and 7,697 urine positive cultures were identified. The unadjusted incident rate was 25.5 /10,000 OBDs in the pre-COVID-19 cohort, and 25.1/10,000 OBDs in the COVID-19 cohort. The overall rate of HAI aggregated for all sites did not differ significantly between the two periods. The two hospitals in one state which experienced an earlier and larger outbreak demonstrated a significant downward trend in the COVID-19 cohort (p = 0.011).ConclusionThese mixed findings reflect the uncertainty of the effect the pandemic has had on HAI’s. Factors to consider in this analysis include local epidemiology, differences between public and private sector facilities, changes in patient populations and profiles between hospitals, and timing of enhanced IPC interventions. Future studies which factor in these differences may provide further insight on the effect of COVID-19 on HAIs.

Supporting patients and their carers to participate in infection prevention and control activities: The views of patients, family members, and hospital staff from Bangladesh, Indonesia, and South Korea

Hand hygiene reminders for healthcare workers (HCWs) are commonly used to empower patients. However, this approach overlooks the role of family carers in delivering direct contact care in Asian countries. Limited knowledge exists regarding empowerment strategies for patients and their family carers in infection prevention and control (IPC) recommendations. This study aimed to provide a comprehensive exploration of IPC empowerment within the context of family involvement in care provision across Bangladesh, Indonesia, and South Korea. In-depth interviews were conducted in 5 tertiary-level hospitals in Bangladesh, Indonesia, and South Korea. A total of 64 participants were interviewed through 57 interviews, including 6 group interviews, comprising 2 groups: (1) patients and their family and private carers; and (2) HCWs. The study identified barriers to engaging patients and family carers in IPC measures. These included concerns about the patient-HCW hierarchical relationship, lack of knowledge about healthcare-associated infection, IPC, and patient zone, perceptions of IPC as a barrier to family connections, and disempowerment of patients in IPC due to family bonds. This study provides diverse perspectives on IPC empowerment, revealing challenges faced by patients, family carers, and HCWs. The interlaced relationship established by social norms of family carer provision hinders the empowerment of family carers. Acknowledging the cultural influence on health care arrangements and its implication for IPC empowerment is crucial in mitigating these barriers.
