The Extra Length of Stay, Costs, and Mortality Associated With Healthcare-Associated Infections: A Case-Control Study.

This study aims to compare the mortality rate, length of stay (LOS), and hospitalization cost in patients with and without healthcare-associated infections (HCAIs). This prospective cohort study is conducted on 396 matched patients admitted to a tertiary teaching hospital with 800 beds in the southwest of Iran from July 2021 to January 2022. The cases were patients admitted during the study period who had, at minimum, one type of HCAI. For a comparison group, we considered all patients without HCAIs who hospitalized in the same ward and at the same time with the same age and gender in a ratio of one case to three controls. Descriptive analyses were done based on direct medical costs, LOS, and mortality rate in patients. The magnitude of the relationship between potential risk factors and HCAI was quantified using logistic regression. The most common HCAI and microorganisms were urinary tract infection (UTI) and Escherichia coli, respectively. The mean LOS for infected patients was 20.3 (±16) days, compared to 8.7 (±8.6) days for noninfected patients (p value ≤ 0.05). Lengths of stay (odds ratio [OR] = 1.09; 95% CI = 1.06-1.19; p value = 0.000), ICU lengths of stay (OR = 1.08; 95% CI = 1.02-1.15; p value = 0.003), presence of central Catheter (OR = 0.127; 95% CI = 0.51-0.319; p value = 0.000), and urinary catheter (OR = 0.225; 95% CI = 0.122-0.415; p value = 0.000), mechanical ventilation (OR = 0.136; 95% CI = 0.57-0.325; p value = 0.000), receipt of immunosuppressors (OR = 1.99; 95% CI = 11.12-3.56; p value = 0.01), were Significantly associated with HCAI. Patients with infections had a more costly hospital stay than noninfected patients (mean diff: $2037.46 ([SD]: 482.25$) (p value = 0.000). The highest cost component was the cost of medication expenditure (mean: $1612.66 ([SD]: $2542.27). UTI was the most common HCAI in our study. An infection acquired during a hospital stay may be associated with higher hospitalization costs, prolonged hospitalization, and an increase in the rate of mortality. Longer lengths of stay, presence of central and urinary Catheters, receipt of immunosuppressors, use of mechanical ventilator were common risk factors for HCAI. This study reveals that the median reimbursement cost per hospitalization of patients with HCAIs was higher than patients without HCAIs. This highlights the necessity for implementation of HCAI prevention and control measures.

Point Prevalence Survey of HAIs as a key component of Infection Prevention and Control programs

Abstract Healthcare-Associated Infections (HAIs) are a global concern, requiring surveillance strategies as Point Prevalence Surveys (PPS) to estimate their burden and investigate associated risk factors for targeted interventions in high-risk areas. This study aims to assess the prevalence of HAIs, identify determinants and evaluate antimicrobial use in a teaching hospital in Rome. A PPS was carried out from June 19th to 23rd, 2023, in accordance with the European Centre for Disease Prevention and Control (ECDC) protocol for HAIs and antimicrobial use in European acute care hospitals (version 6.1). Pearson’s chi-squared test was employed to investigate correlations between potential risk factors and HAIs. The survey included 829 patients with an average age of 56.3 years (SD: ±24.6). Of these, 48.4% were female and over half had visited the hospital’s Emergency Department (53.7%). The prevalence of active HAIs was 8.7%, with 72 patients diagnosed. Furthermore, 51.0% of all patients received at least one systemic antimicrobial agent, and 16.7% of those treated had an HAI. Penicillins (39.7%) and third-generation cephalosporins (37.8%) were the most frequently prescribed antimicrobials. The primary HAIs were bloodstream infections (34.1%), followed by urinary tract (27.3%), surgical site (23.9%), lower respiratory tract (6.8%), and gastrointestinal infections (7.9%). Escherichia coli (13.2%), Staphylococcus aureus (9.2%), and Clostridium difficile (6.6%) were the most frequently isolated pathogens. Intensive Care Unit admission, use of medical device, recent antibiotic therapy and prior hospitalization or surgery significantly correlated (p < 0.05) with increased HAIs risk. The detected prevalence of HAIs is lower than the national rates observed in 2022 (10.2%), which have increased since 2016. HAIs surveillance is essential for developing effective infection prevention and control programs and for optimizing resource allocation in hospital settings. Key messages • Surveillance of Healthcare-Associated Infections is crucial for developing targeted Infection Prevention and Control programs and optimizing hospital resource allocation. • Point Prevalence Surveys offer essential information for assessing the burden of Healthcare-Associated Infections and directing intervention strategies in hospitals.

Molecular surveillance of A. baumannii in intensive care units: exploration of transmission chains

Abstract Background Multidrug-resistant Acinetobacter baumannii (MDR-Ab) is one of the main causes of healthcare associated infections (HAIs). During the SARS-CoV-2 pandemic there was an increase in MDR-Ab infections, especially in intensive care units (ICUs). This study aimed to assess the potential spread or emergence of specific clusters of MDR-Ab across four different ICUs at the Umberto I teaching hospital of Rome. Methods From January 2020 to January 2022 microbiological surveillance was conducted in four ICUs: two dedicated to COVID-19 patients (ICU-1C, ICU-2C) and two to non-COVID-19 patients (ICU-1R, ICU-2R). The genetic relatedness between A. baumannii isolates was assessed using pulsed-field gel electrophoresis (PFGE). Illumina whole genome sequencing was conducted on 26 representative isolates. Results In total, 178 A. baumannii isolates were obtained from 129 COVID-19 patients and 49 non-COVID-19 patients. The isolates were classified into 17 PFGE pulsotypes, being two major (A, B) and five intermediate (C, D, E, H, Q). Clone A was present in all ICUs, while Clone B was present only in ICU-1C and ICU-2R. Overall, 117 isolates belonged to clone A and exhibited a MDR phenotype; all of them were placed within the international clonal lineage II. All isolates showed carbapenems resistance primarily attributed to the presence of the blaOXA-23 gene, while aminoglycosides resistance observed in almost all isolates was attributed to the presence of the armA gene. Small outbreaks involving intermediate pulsotypes were detected between ICU-1R and ICU-2R, ICU-1C and ICU-2R, ICU-1C and ICU-2C, ICU-1C and ICU-1R. Conclusions The observed outbreaks could be attributed to a decline in attention to normal care practices for the prevention of HAIs during the COVID-19 pandemic, favouring the spread of MDR-Ab. Therefore, it is recommended the strengthen of control measures and the implementation of long-term strategies targeting MDR microorganisms in the ICUs. Key messages • Acinetobacter baumannii was frequently found infecting patients across four different ICUs at the Umberto I teaching hospital of Rome. • Acinetobacter baumanni outbreaks and multidrug resistance were observed. Therefore, the implementation of long-term strategies targeting MDR microorganisms in the ICUs is highly recommended.

Risk perception survey for healthcare-associated infections in a large teaching hospital in Rome

Abstract Background Healthcare-associated infections (HAIs) are the main complications of hospitalization. The goal of the study was to enhance awareness, improve risk perception, and facilitate measures to reduce the outcomes of HAIs. A bottom-up approach, in which the healthcare workers involved play a key role, can be adopted to decrease the spread of HAIs. Therefore, a survey was conducted in a large teaching hospital in Rome from 2019 to 2023, excluding 2020 due to COVID-19. Methods A longitudinal study was conducted in all integrated care departments with beds. The data was collected using a standardized, anonymous, self-administered questionnaire for healthcare workers. The questionnaire consisted of 61 items assessing socio-professional features, knowledge of HAIs, attitudes and barriers to hygiene compliance, self-analysis of professional behavior and advice for new interventions. The study lasted 21 days between November and December, which is considered a period of normal care activity. A multivariable logistic regression model was built. Statistical analyses were performed with STATA 18.0. Results There were 384 health workers respondents: female (67.7%) and nurses (56.5%). The most represented areas were internal medicine (37.9%) and surgery (27.3%). The correct frequency of perception of HAIs increased from 33.3% in 2019 to 36.3% in 2023. From 2022 to 2023, the multivariable model showed that physicians (OR 0.48, CI 95% 0.24-0.93, p-value 0.03) and elder staff (OR 1.02, CI 95%, 1.0-1.1, p-value 0.04) seemed to be more aware of the prevalence of HAIs in their ward. Conclusions Targeted training days were organized after the study to discuss the data collected. Staff awareness of the prevalence of HAIs in their ward is improving, even if it is complicated to quantify it by attending HAIs training events. The survey has been included as a corporate goal for 2024 as a useful tool to improve awareness of HAIs and to evaluate the effectiveness of ongoing training. Key messages • A bottom-up approach, in which healthcare workers assume a pivotal role, can be employed to reduce the spread of HAIs as it serves as a valuable tool to evaluate the efficacy of targeted training. • The results indicate that the education of healthcare workers is a crucial factor in enhancing awareness of HAIs. Therefore, there is a need to improve the education of younger and non-medical staff.

Fighting HAIs by monitoring hand hygiene compliance in the Umberto I teaching Hospital in Rome

Abstract Background Healthcare-associated infections (HAIs) are one of the most common preventable complications in hospitalised patients related to increased morbidity and mortality for patients. Proper hand hygiene (HH) can decrease the prevalence of HAIs within care settings. The aim of the study was to evaluate the effects of a monitoring and feedback system on HH compliance (HHC). Methods Three monitoring and feedback studies have been carried out in Umberto I teaching hospital of Rome since 2021. Healthcare workers (HCWs), were trained on how to carry out the direct observation on the 5 WHO moments on HH. The data collection lasted two weeks each year. Following data collection, they were analysed and discussed annually with HCWs. A multivariable logistic regression model was constructed to identify predictors of HH compliance. Results A total of 15874 HH were observed, of which 40.1% in 2023. The recorded HHC was 71.0% in 2021, 75.4% in 2022 and 71.6% in 2023. Multivariable analyses showed that HHC was positively associated with female sex of observed (aOR:1.3, 95% CI:1.1-1.4), during weekend days or holidays (aOR:1.3 95% CI:1.1-1.4) and all indications with respect to ‘before touching a patient’. Regarding the professional category of the observer, compared to physicians, midwives were more likely to report compliant observations (aOR=2.4, 95% CI: 1.4-4.1). On the other hand, a negative association was found with external ward staff and other HCWs and no-HCWs compared to physicians. Ward area and year of observation did not influence the probability of the outcome. Conclusions The results of this study revealed sub-optimal adherence to HH, with the lowest rates observed prior to patient interaction. That, coupled with the variability seen among HCWs, underlines the difficulties in achieving a uniform level of compliance. Therefore, ongoing training to raise awareness among HCWs and to repeat the survey over time identifying any major problems is essential. Key messages • Monitoring the reasons for non-adherence to hand hygiene in healthcare institutions in order to formulate strategies to improve HH adherence among hospital staff is essential. • Hand hygiene (HH) monitoring systems can produce measurable improvements in HH adherence by healthcare personnel, resulting in a reduction in the incidence of healthcare-associated infections.

Point-Prevalence Survey of Antimicrobial Use and Healthcare-Associated Infections in Four Acute Care Hospitals in Kazakhstan.

Few studies have examined the prevalence of healthcare-associated infections (HAIs) and antimicrobial use (AMU) in acute care hospitals in Kazakhstan. This study aimed to address this gap by conducting a point-prevalence survey (PPS) of HAIs and AMU, as well as evaluating hospital antibiotic consumption via internationally recognized methodologies. PPS was conducted in four acute care hospitals in Kazakhstan on 11 May 2022, following the methodology of the European Center for Disease Prevention and Control, and included 701 patients. Antibiotic consumption in the same hospitals was assessed via the Global Antimicrobial Resistance and Use Surveillance System methodology. HAIs were observed in 3.8% of patients (27/701), with intensive care unit wards accounting for 48.1% of these cases (13/27). Pseudomonas aeruginosa was the most frequently identified pathogen (5 out of 14 documented cases, 35.7%). Resistance to carbapenems was the most common resistance, followed by resistance to glycopeptides and third-generation cephalosporins. The rate of AMU was 38.2%, with an average of 1.37 antibiotics administered per patient. Surgical prophylaxis lasting more than one day was the most common indication for antimicrobial prescription (44.8%). Ceftriaxone and cefazolin are the most commonly used antibiotics. The results of this study are important for understanding the current situation in Kazakhstan and for informing national antimicrobial stewardship and infection control strategies.

Microflora of Secretions in a Surgical Hospital of Orthopedics and Traumatology Profile for 2021-2023 (SI “ITO NAMS of Ukraine”)

Summary. Healthcare-associated infections (HAIs), namely, surgical site infections, early postoperative and subsequent in-hospital infections, are the most common undesirable phenomenon in the world. According to statistics, at least one case of HAIs is diagnosed in every 100 hospitalized patients in hospitals of 7 developed and 15 other countries of the world at any given time. The occurrence of such complications during the treatment of a patient in a hospital leads to the need of additional diagnostic tests, additional courses of antibiotics, and unplanned surgical intervention. Worsening of the prognosis of treatment may occur due to the formation of the so-called resistant microflora in such patients, with a real probability of spreading the infection in the hospital. Prevention of HAIs in practice occurs through planned infection control in operating rooms and procedure rooms in clinical departments and qualified timely diagnostic work of certified microbiological laboratories in hospitals. Objective. The objective of the study was to determine the spectrum of microflora of secretions for three years (2021-2023) in orthopedic and trauma patients due to changes in modern injuries received more often because of military aggression and to propose the identified differences as criteria for prescribing antibacterial drugs in complex inpatient treatment. The work shows that over the past three years (2021-2023), the ratio of gram-positive and gram-negative microorganisms in the study material almost did not change and averaged 1.65. The peculiarity of the analyzed period was an increase in the number of methicillin-resistant staphylococci by 1.3 times. The spectrum of gram-negative clinical strains has changed, namely, the number of Kl.pneumoniae clinical strains with a high level of polyresistance has increased by 2.5 times. The obtained data made it possible to identify the spectrum of microflora of secretions in orthopedic and trauma patients with modern infectious complications, which prompts us to make changes in the standards of antibacterial treatment protocols, and to plan the needs for certain antibiotics in hospitals with personalization of their prescription to improve the effectiveness of treatment and reduce the risk of development of antimicrobial resistance.

Healthcare-associated infections in Japanese hospitals: results from a large-scale multicenter point-prevalence survey in Aichi, 2020.

Healthcare-associated infections (HAIs) pose significant challenges to healthcare systems worldwide. Epidemiological data are essential for effective HAI control; however, comprehensive information on HAIs in Japanese hospitals is limited. This study aimed to provide an overview of HAIs in Japanese hospitals. A multicenter point-prevalence survey (PPS) was conducted in 27 hospitals across the Aichi Prefecture between February and July 2020. This study encompassed diverse hospital types, including community, university, and specialized hospitals. Information on the demographic data of the patients, underlying conditions, devices, HAIs, and causative organisms was collected. A total of 10,199 patients (male: 5,460) were included in this study. The median age of the patients was 73 (interquartile range [IQR]: 56-82) years, and the median length of hospital stay was 10 (IQR: 4-22) days. HAIs were present in 6.6% of patients, with pneumonia (1.83%), urinary tract infection (1.09%), and surgical site infection (SSI) (0.87%) being the most common. The prevalence of device-associated HAIs was 0.91%. Staphylococcus aureus (17.3%), Escherichia coli (17.1%), and Klebsiella pneumoniae (7.2%) were the primary pathogens in 433 organisms; 29.6% of the Enterobacterales identified showed resistance to third-generation cephalosporins. Pneumonia was the most prevalent HAI in small-to-large hospitals (1.69%-2.34%) and SSI, in extra-large hospitals (over 800 beds, 1.37%). This study offers vital insights into the epidemiology of HAIs in hospitals in Japan. These findings underscore the need for national-level PPSs to capture broader epidemiological trends, particularly regarding healthcare challenges post-COVID-19.

NanoCore: core-genome-based bacterial genomic surveillance and outbreak detection in healthcare facilities from Nanopore and Illumina data.

Genomic surveillance involves sequencing the genomes and measuring the relatedness of bacteria from different patients or locations in the same healthcare facility, enabling an improved understanding of pathogen transmission pathways and the detection of "silent" outbreaks that would otherwise go undetected. It has become an indispensable tool for the detection and prevention of healthcare-associated infections and is routinely applied by many healthcare institutions. The earlier an outbreak or transmission chain is detected, the better; in this context, the Oxford Nanopore sequencing technology has important potential advantages over traditionally used short-read sequencing technologies, because it supports "real-time" data generation and the cost-effective "on demand" sequencing of small numbers of bacterial isolates. The analysis of Nanopore sequencing data, however, can be challenging. We present NanoCore, a user-friendly software for genomic surveillance that works directly based on Nanopore sequencing reads in FASTQ format, and demonstrate that its accuracy is equivalent to traditional gold standard short read-based analyses.

Advancing Patient Safety: The Future of Artificial Intelligence in Mitigating Healthcare-Associated Infections: A Systematic Review.

Healthcare-associated infections are infections that patients acquire during hospitalization or while receiving healthcare in other facilities. They represent the most frequent negative outcome in healthcare, can be entirely prevented, and pose a burden in terms of financial and human costs. With the development of new AI and ML algorithms, hospitals could develop new and automated surveillance and prevention models for HAIs, leading to improved patient safety. The aim of this review is to systematically retrieve, collect, and summarize all available information on the application and impact of AI in HAI surveillance and/or prevention. We conducted a systematic review of the literature using PubMed and Scopus to find articles related to the implementation of artificial intelligence in the surveillance and/or prevention of HAIs. We identified a total of 218 articles, of which only 35 were included in the review. Most studies were conducted in the US (n = 10, 28.6%) and China (n = 5; 14.3%) and were published between 2021 and 2023 (26 articles, 74.3%) with an increasing trend over time. Most focused on the development of ML algorithms for the identification/prevention of surgical site infections (n = 18; 51%), followed by HAIs in general (n = 9; 26%), hospital-acquired urinary tract infections (n = 5; 9%), and healthcare-associated pneumonia (n = 3; 9%). Only one study focused on the proper use of personal protective equipment (PPE) and included healthcare workers as the study population. Overall, the trend indicates that several AI/ML models can effectively assist clinicians in everyday decisions, by identifying HAIs early or preventing them through personalized risk factors with good performance. However, only a few studies have reported an actual implementation of these models, which proved highly successful. In one case, manual workload was reduced by nearly 85%, while another study observed a decrease in the local hospital's HAI incidence from 1.31% to 0.58%. AI has significant potential to improve the prevention, diagnosis, and management of healthcare-associated infections, offering benefits such as increased accuracy, reduced workloads, and cost savings. Although some AI applications have already been tested and validated, adoption in healthcare is hindered by barriers such as high implementation costs, technological limitations, and resistance from healthcare workers. Overcoming these challenges could allow AI to be more widely and cost-effectively integrated, ultimately improving patient care and infection management.

The burden of healthcare-associated infections in New Zealand public hospitals 2021.

There are no contemporary data on the burden of healthcare-associated infections (HAIs) in New Zealand. To estimate the economic burden of HAIs in adults in New Zealand public hospitals by number and monetary value of bed days lost; number of deaths, number of life years lost, and the monetary value (in NZ dollars); Accident Compensation Commission (ACC) HAI treatment injury payments; and disability-adjusted life years (DALYs). The annual incidence rate was calculated from the observed prevalence of HAIs in New Zealand, and length of patient stays. Total HAIs for 2021 were estimated by multiplying adult admissions by incidence rates. The excess length of stay and mortality risk attributed to those with HAI was calculated using a multistate model. Payments for treatment injuries were obtained from the ACC. DALYs for HAIs were estimated from the literature. The incidence rate of HAI was 4.74%, predicting 24,191 HAIs for 2021, resulting in 76,861 lost bed days, 699 deaths, with 9,371 years of life lost (YoLL). The annual economic burden was estimated to be $955m comprised of $121m for lost bed days, $792m for cost of YoLL, and $43m ACC claims. There were 24,165 DALY which is greater than many other measured injuries in New Zealand, eg motor vehicle traffic crashes with 20,328 DALY. HAIs are a significant burden for patients, their families, and the public health system. Preventive guidelines for many HAIs exist and a strategic plan is needed to reduce HAIs in New Zealand.

Potenciar as práticas pedagógicas dos docentes e tutores de Enfermagem na Prevenção de Infeções Associadas aos Cuidados de Saúde: Estudo Piloto PrevInf

Background: Healthcare-associated infections (HAIs) pose a significant challenge in Southeast Asia. Despite various reforms in the curricula of this region, health courses have not adequately addressed the prevention of HAIs. Objective: To evaluate the perceptions of nursing educators in Southeast Asia regarding an innovative educational approach developed by the PrevInf project consortium. Methods: A pilot study was conducted using a quantitative approach and descriptive design at two universities in Cambodia and two in Vietnam. Nursing educators were invited to participate in a training session that included a presentation of the PrevInf Model, the pedagogical materials, and the simulation scenarios developed by the project consortium. After the session, the nursing educators completed a questionnaire to assess their agreement with a set of statements concerning the outputs’ feasibility, adequacy, and applicability. Results: The study included 121 nursing educators who reported high agreement regarding the feasibility of the PrevInf Model and its acceptability in various contexts, with no statistically significant differences observed between countries. Across both countries, participants expressed moderate to high agreement that the simulation scenarios represent an appropriate pedagogical strategy and adequately cover essential topics related to the prevention of HAIs. Conclusion: Nursing educators believe that the PrevInf Model, along with its pedagogical materials and simulation scenarios, demonstrates high adequacy, acceptability, and feasibility, with the potential to enhance students' knowledge and skills in HAI prevention. Further research is needed to refine the cultural relevance of the PrevInf Model when compared to traditional teaching methods.

Interactive hygiene training using free open source software.

Regular hygiene trainings are an important way to refresh and improve knowledge about hygiene measures and the prevention of healthcare-associated infections. We aimed to develop an e-learning course to allow healthcare workers (HCWs) to learn these contents through a self-paced online format. We developed an interactive hygiene training for HCWs of a tertiary care hospital using different content types of the HTML-5 package (H5P) plugin embedded into a Moodle-based learning management system. We evaluated the course using a short online questionnaire. We present various suitable topics for online hygiene trainings as well as their implementation in an e-learning course. Examples include content on hand hygiene indications and techniques, information on multidrug-resistant organisms and other current topics in infection control. HCWs reported high overall satisfaction, perceived increase in knowledge, practical relevance as well as good usability and comprehensibility. Currently available commercial and non-commercial hygiene trainings present a number of specific advantages but also drawbacks. The presented approach combines the advantages of both approaches. The majority of the presented content can be readily adapted to suit various hospitals and care facilities or serve as inspiration for creating similar courses while remaining cost-effective. H5P course presentations are a low-threshold, cost-effective way to implement digital hygiene trainings in a wide variety of clinical settings.

Inverse probability weighting leads to more accurate incidence estimates for healthcare-associated infections in intensive care units – results from two national surveillance systems

Two main approaches are employed to monitor healthcare associated infections (HAIs): longitudinal surveillance, which allows to measure incidence rates, and point prevalence surveys (PPS). PPS are less time-consuming; however, they are affected by length-biased sampling, which can be corrected through inverse probability weighting. We assessed the accuracy of this method by analysing data from two Italian national surveillance systems. Ventilator associated pneumonia (VAP) and central-line associated bloodstream infection (CLABSI) incidence measured through a prospective surveillance system (GiViTI) was compared to incidence estimates obtained through conversion of crude and inverse probability weighted prevalence of the same HAIs in intensive care units (ICUs) measured through a PPS. Weighted prevalence rates were obtained after weighting all patients inversely proportional to their time-at-risk. Prevalence rates were converted into incidence per 100 admissions using an adapted version of the Rhame and Sudderth formula. Overall, 30988 patients monitored through GiViTI, and 1435 patients monitored through the PPS were included. A significant difference was found between incidence rates estimated based on crude VAP and CLABSI prevalence and measured through GiViTI (relative risk, RR 2.5 and 3.36; 95% confidence interval, CI 1.42 - 4.39 and 1.33 - 8.53, p = 0.006 and 0.05 respectively). Conversely, no significant difference was found between incidence rates estimated based on weighted VAP and CLABSI prevalence and measured through GiViTI (p = 0.927 and 0.503 respectively). When prospective surveillance is not feasible, our simple method could be useful to obtain more accurate incidence rates from PPS data.

Healthcare-associated infections in patients with COVID-19: is it different from the pre-pandemic period?

Healthcare-associated infections (HAIs) are common in intensive care unit (ICU) patients and may cause devastating consequences. However, the prevalence of HAI and its effects on in-hospital mortality among critically ill COVID-19 patients is ambiguous. We determined the prevalence of HAI and the rate of mortality in critically ill COVID-19 patients and compared it with pre-pandemic ICU patients. This retrospective study was conducted with adult ICU patients admitted to Gazi Yaşargil Training and Research Hospital (Diyarbakir,Turkey) in April-November 2019 (defined as the pre-pandemic period) and in April-November 2020 (defined as the pandemic period). All patients in the pandemic period had COVID-19, while none in the pre-pandemic period did. Patients diagnosed with HAIs during the in-hospital follow-up period were recorded. Of 4596 enrollees, 3386 (73.7%) were pandemic-period patients and 1210 (26.3%) were pre-pandemic-period patients. HAI prevalence was significantly higher at 5.9% (n = 71) in the pandemic-period patients and 2.7% (n = 91) in the pre-pandemic-period patients (p < 0.001). Comorbidities including hypertension (63.4% vs 14.2%, p < 0.001), diabetes mellitus (39.4% vs 8.8%, p < 0.001), and coronary artery disease (30.9% vs 10.9%, p = 0.002) were significantly more frequent in pandemic-period HAI-positive patients. The most common HAI was catheter-related bloodstream infection in both groups, with similar frequency (p = 0.652). In-hospital mortality rate was 85.9% versus 65.9% in pandemic- versus pre-pandemic-period HAI-positive patients (p < 0,05). The prevalence of HAI and the in-hospital mortality rate was significantly higher among pandemic-period patients.

Baseline evaluation of the World Health Organization (WHO) infection prevention and control (IPC) core components in Pacific Island Countries and Territories (PICTs)

BackgroundComprehensive infection prevention and control (IPC) programmes are proven to reduce the spread of healthcare-associated infections (HAIs) and antimicrobial resistance (AMR). However, published assessments of IPC programmes against the World Health Organization (WHO) IPC Core Components in Pacific Island Countries and Territories (PICTs) at the national and acute healthcare facility level are currently unavailable.MethodsFrom January 2022 to April 2023, a multi-country, cross-sectional study was conducted in PICTs. The self reporting survey was based on the WHO Infection Prevention Assessment Framework (IPCAF) that supports implementing the minimum requirements of the WHO eight core components of IPC programmes at both the national and facility level. The results were presented as a ‘traffic light’ (present, in progress, not present) matrix. Each PICT’s overall status in achieving IPC core components was summarised using descriptive statistics.ResultsFifteen PICTs participated in this study. Ten (67%) PICTs had national IPC programmes, supported mainly by IPC focal points (87%, n = 13), updated national IPC guidelines (80%, n = 12), IPC monitoring and feedback mechanisms (80%, n = 12), and waste management plans (87%, n = 13). Significant gaps were identified in education and training (20%, n = 3). Despite being a defined component in 67% (n = 10) of national IPC programmes, HAI surveillance and monitoring was the lowest scoring core component (13%, n = 2). National and facility level IPC guidelines had been adapted and implemented in 67% (n = 10) PICTs; however, only 40% (n = 6) of PICTs had a dedicated IPC budget, 40% (n = 6) had multimodal strategies for IPC, and 33% (n = 5) had daily environmental cleaning records.ConclusionsIdentifying IPC strengths, gaps, and challenges across PICTs will inform future IPC programme priorities and contribute to regional efforts in strengthening IPC capacity. This will promote global public health through the prevention of HAIs and AMR.

Healthcare-Associated Infections: Pre- and Post-pandemic Microbiological Profile and Antibiotic Resistance.

In recent years, healthcare-associated infections (HAIs) have been a priority topic for global institutions such as the World Health Organization because, during the COVID-19 pandemic, the role of HAIs as co-morbidity in infected patients was evident. HAIs can cause disability and mortality and lead to excessive healthcare costs. This work aims to calculate the prevalence of HAIs from 2019 to 2023 to determine their microbiological profile and antibiotic resistance. A cross-sectional design was used for this study. To describe the population, univariate analysis, measures of central tendency, frequencies, and proportions were used. The present study included 3,936 HAI notifications, which showed a significant decrease in their number during the COVID-19 pandemic, especially in 2020. In 2021 and 2022, the numbers increased rapidly to around 30%. The most prevalent HAI type was ventilator-associated pneumonia, which had the highest prevalence in 2020. Regarding microorganism isolation, percentages increased after 2020 from 46% to 67%, with Acinetobacter baumannniibeingthe most frequent during and after pandemics. The microbiological profile showed multidrug resistance in several microorganisms. HAIs are a global health concern. The number of cases has been increasing since the COVID-19 pandemic with regard to the multidrug-resistant microorganism. HAIs have an important impact on the quality of life, morbidity, mortality, and financial concerns for health services. Global strategies should be adapted for different regions, since the panaroma in developed countries allows for programs to be established for the prevention and control of HAIs in a better way than in low-income countries that lack adequate infrastructure and resources.

Factors Affecting Student Nurses’ Adherence to Standard Precautions for Preventing Tuberculosis and HIV at Eswatini University

Background The prevention of Healthcare-associated Infections (HAIs) has become an increasing challenge throughout the world. Tuberculosis (TB) and Human Immunodeficiency Virus (HIV) are among the infections that student nurses are at risk of acquiring during their clinical practice in the healthcare setting. One of the most essential measures used to control HAIs is the application of standard precautions. However, student nurses have been found to not adhere to the standard precautions for the prevention of TB and HIV when allocated for clinical practice in the Eswatini healthcare setting. Aim This study aimed to assess factors affecting student nurses’ adherence to standard precautions. Methods A non-experimental quantitative approach was used to conduct a survey on senior student nurses of Eswatini University using the questionnaires. The total population of third-, fourth-, and fifth-year students was selected through the census sampling method. Statistical Package for Social Science version 26 software was used to analyze the data. Results Factors influencing compliance with standard precautions for the prevention of TB and HIV have been categorized into the availability of resources, measures taken by student nurses, hospital support role, and university support role. Conclusion The researchers recommend that TB and HIV prevention skills be demonstrated to student nurses in the skills laboratory and that clinical facilitators should accompany students in the clinical area. In the hospitals, ordering and monitoring of supplies should be done well to eliminate the shortage of resources, and preceptors should be exempted from other duties so that they can be able to supervise student nurses.

Prevalence of Healthcare-Associated Infections in a Tertiary Hospital in Casablanca, Morocco, 2021.

During the COVID-19 pandemic, healthcare professionals experienced an increased workload, which may have affected infection prevention and control (IPC) programs and consequently healthcare-associated infection (HAI) rates. The objective of this study was to estimate the prevalence of HAI in Ibn Rochd University Hospital Center (IRUHC) and identify associated factors. A survey was conducted on November 30, 2021 at IRUHC, including all patients hospitalized for at least 48 hours. Data was collected using a questionnaire, and analyzed using SPSS IBM software version 16. The significance level was set at 0.05. Among 887 patients, the prevalence of HAI was 9.7% (7.7%; 11.6%). The highest prevalence was observed in intensive care units (ICUs) (44.2%). Nosocomial pneumonia was the most common site (26.8%). The main isolated microorganisms were Acinetobacter baumannii (18.0%) and Escherichia coli (16.0%). All Acinetobacter baumannii isolated strains were imipenem-resistant. The presence of HAI was significantly associated with the presence of an invasive medical device (p<0.001), a higher physical status score of American Society of Anesthesiologists (ASA) (p<0.001), and a longer hospital stay (p<0.001). Conclusion: The emergence of imipenem-resistant Acinetobacter baumannii(IRAB) represents a serious therapeutic and epidemiological problem requiring the establishment of a system for monitoring the microbial environment and the application of strict hygiene measures.

Current challenges in teaching healthcare-associated infections prevention and control in nursing education in Vietnam and Cambodia: a qualitative study.

Background: There is an insufficient understanding of factors that impede nursing students' learning of healthcare-associated infection prevention and control in developing countries. This study aimed to explore current challenges in healthcare-associated infection control and prevention education in the nursing curriculum in two Vietnamese and two Cambodian universities. Methods: Exploratory research was conducted through consultation of education programs and a qualitative study design utilizing interviews and focus group discussions. Data collection was conducted through interviews with university board members and focus group discussions with lecturers and tutors. The data were analyzed by using content analysis methods. Results: The research results indicated that there were three generic themes of challenges in teaching HAIs-PC in nursing education in Vietnam and Cambodia. They were Implementation of healthcare associated infections prevention and control education into nursing curriculum, Positive aspects fostering healthcare associated infections prevention and control learning, Negative aspects hindering healthcare associated infections prevention and control learning. Conclusions: The study results provided evidence of challenges in healthcare associated infections prevention and control education in some Asia higher education institutions. To improve professional safety, universities should pay more attention to developing appropriate teaching methods for healthcare-associated infections prevention and control education to improve students' practice outcomes.
