Effect of ventilator care bundle for pediatric nurses on occurrence of ventilator-associated pneumonia among children

BACKGROUND

In pediatric intensive care units (PICUs), ventilator-associated pneumonia (VAP) is one of the most prevalent infections linked to healthcare. VAP affects 10% of children on mechanical ventilation (MV) and is associated with severe morbidity and mortality. The study aimed to evaluate the effect of the ventilator care bundle (VCB) on the occurrence of VAP among pediatric patients.

METHOD

A quasi-experimental design was conducted at Cairo University Specialized Pediatric Hospital (CUSPH), including all children who had mechanical ventilation within 24 h. VAP rates were evaluated before and after the implementation of a comprehensive VCB, which included head-of-bed elevation to 30-45°, hand hygiene reinforcement, sterile suctioning and handling of respiratory equipment, daily evaluation of extubation readiness, peptic ulcer prophylaxis, and deep venous thrombosis prophylaxis. A convenience sample of 30 nurses and a purposive sample of 60 ventilated children in the PICU participated in the study. Data collection was performed using (1) structured interview sheets, (2) the Nurses' Knowledge Assessment Questionnaire (pre/post-test), (3) the Ventilator Bundle Checklist, and (4) the Clinical Pulmonary Infection Scale (CPIS).

RESULTS

There was a significant increase in nurses' level of knowledge before and after the implementation of the VCB (X² = 21.46, p ≤ 0.01). There was a statistically significant difference between the total mean scores of nurses' practices in the first and second checklist readings (p < 0.01). Additionally, there were statistically significant differences between children in the study and control groups regarding the clinical pulmonary infection score (p < 0.01). The total mean score on the CPIS was significantly different between the study group and the control group (t = - 3.692, p = 0.001).

CONCLUSION

The study concluded that children who were cared for by nurses receiving VCB sessions were less likely to experience VAP compared to those in the control group.

RECOMMENDATION

Educational programs and in-service training courses for pediatric nurses to improve the quality of ventilator care for children and reduce the occurrence of VAP are essential.

Central line-associated bloodstream infection rates in intensive care units of China's hospitals: a meta-analysis

Background and aim

Various reasons have hindered accurate reporting of the central line-associated bloodstream infection (CLABSI) rates in China's hospital ICUs. This study conducts a meta-analysis to provide a precise assessment of CLABSI rates in these units.

Methods

Adhering to the PRISMA guidelines, a systematic search was conducted in PubMed, Web of Science, Embase, CNKI, Wanfang and Weipu from January 2008 to December 2023. Selection of literature followed strict criteria, ensuring relevant data extraction. A random-effects model facilitated the meta-analysis.

Results

The analysis incorporated 23 studies (PubMed: 5, Web of Science: 4, Embase: 1, CNKI: 9, Wanfang: 2, Weipu: 2). It revealed an overall weighted CLABSI rate in China's ICUs of 2.65‰ (95% CI: 2.57-2.73‰), with 3.12‰ in adult ICU (95% CI: 2.70-3.54‰) and 2.57‰ in pediatric ICUs (95% CI: 2.49-2.66‰). Notably, adult ICUs in North of China recorded the highest rate at 5.13‰ (95% CI: 4.23-6.02‰), and pediatric ICUs in East of China had 3.35‰ (95% CI: 2.85-3.85‰).

Conclusion

The study indicates that CLABSI rates in China's ICUs surpass those reported in national healthcare reports and the US CDC-NHSN data. This underscores the urgency for enhanced surveillance and infection control. The findings stress the need for standardized surveillance definitions and methods to truly represent CLABSI epidemiology and develop effective prevention strategies.

Chlorhexidine solutions are more effective than povidone-iodine solutions as skin disinfectants for the prevention of intravascular catheter-related infections: A meta-analysis

Catheter-related infections pose a significant risk to critically ill patients, making it crucial to select an appropriate sterilization solution. However, there is currently no consensus on the use of chlorhexidine-containing solutions or povidone-iodine (PVI) and the auxiliary ingredients in solutions. Meta-analysis. PubMed, EMBASE, OVID, Web of Science, and Cochrane Library databases. Two reviewers independently performed study screening and data extraction and used the Cochrane risk-of-bias tool 2.0 (RoB 2.0) for quality assessment. We included 10 fully published RCTs with 12 pairs of comparisons, which included a total of 9,689 catheters. The analysis revealed that chlorhexidine gluconate (CHG)-containing solutions were significantly more effective than PVI in preventing CRBSI (RR = 0.460, 95% CI 0.323-0.654, P < 0.001), catheter-related sepsis (RR = 0.419, 95% CI 0.206-0.853, P = 0.016), and catheter colonization (RR = 0.409, 95% CI 0.266-0.630, P < 0.001). Further subgroup analysis demonstrated that, regardless of the concentration of CHG (≤ 1% or > 1%), it was superior to PVI in preventing CRBSI and catheter colonization (RR = 0.271 ~ 0.585, 95% CI 0.110 ~ 0.400‒0.590‒0.926). CHG-alcohol is most effective at preventing catheter-related infections, especially those caused by 70% alcohol. Compared to PVI, CHG-70% alcohol is the most effective disinfectant for preventing catheter-related infections, as it combines the rapid disinfection and evaporation properties of alcohol with the prolonged antimicrobial effects of chlorhexidine.PROSPERO registration number: CRD42024507163.

Assessing infection related to short-term central venous catheters in the perioperative setting

Central venous catheter (CVC) cannulation can be accompanied by serious complications. The appearance of catheter-related infections is associated with high morbimortality. The aim of this study is to evaluate the incidences of colonization and central line-associated bloodstream infections (CLABSI) in short-term CVCs in the elective surgery setting, as well as to analyze the related risk factors. Prospective observational study including patients undergoing elective surgery with a CVC inserted perioperatively. Patients with current infection, taking preoperative antibiotics, those planning to have CVC for longer than 14 days, those under 18 years old, and those refusing to participate were excluded. Patients without cultures at the moment of CVC retrieval were not included. 200 patients were included, with a mean catheter duration of 6.8 ± 3.1 days, and a total duration of 1,358 days. Incidence of colonized catheters was 6% (8.84/1000 catheter-days), and 3.5% had CLABSI (5.15/1000 catheter-days). Catheter duration was longer in patients whose CVCs had been removed due to suspected infection (p < 0.0001). The risk factors for catheter colonization were a history of oncological disease (p = 0.022), ischemic heart disease (p = 0.019), as well as jugular venous catheterization (p = 0.019). No relationship was detected between colonization and operator experience (p = 0.050), ultrasound-guided cannulation (p = 0.565), or number of attempts (p = 0.379). The risk factors for CLABSI were: age over 60 years (p = 0.041) and oncological disease (p = 0.021). CLABSI was neither related to operator experience (p = 0.178), ultrasound-guided cannulation (p = 0.373), or number of attempts (p = 0.379). Although CVCs were in place for a short time and in a controlled setting, we observed high incidences of colonization and CLABSI. The risk of catheter colonization depends on other factors rather than catheter duration.

Food and Waterborne Cryptosporidiosis from a One Health Perspective: A Comprehensive Review

A sharp rise in the global population and improved lifestyles has led to questions about the quality of both food and water. Among protozoan parasites, Cryptosporidium is of great importance in this regard. Hence, Cryptosporidium's associated risk factors, its unique characteristics compared to other protozoan parasites, its zoonotic transmission, and associated economic losses in the public health and livestock sectors need to be focused on from a One Health perspective, including collaboration by experts from all three sectors. Cryptosporidium, being the fifth largest food threat, and the second largest cause of mortality in children under five years of age, is of great significance. The contamination of vegetables, fresh fruits, juices, unpasteurized raw milk, uncooked meat, and fish by Cryptosporidium oocysts occurs through infected food handlers, sewage-based contamination, agricultural effluents, infected animal manure being used as biofertilizer, etc., leading to severe foodborne outbreaks. The only Food and Drug Administration (FDA)-approved drug, Nitazoxanide (NTZ), provides inconsistent results in all groups of patients, and currently, there is no vaccine against it. The prime concerns of this review are to provide a deep insight into the Cryptosporidium's global burden, associated water- and foodborne outbreaks, and some future perspectives in an attempt to effectively manage this protozoal disease. A thorough literature search was performed to organize the most relevant, latest, and quantified data, justifying the title. The estimation of its true burden, strategies to break the transmission pathways and life cycle of Cryptosporidium, and the search for vaccine targets through genome editing technology represent some future research perspectives.

Investigation of Carbapenemase-Producing Pseudomonas aeruginosa at Secondary Care Hospital in Bolu, Turkey

The global increase in carbapenem resistance poses a significant public health threat due to the potential emergence of multidrug-resistant pathogens and limited treatment options. To learn more about this issue and offer potential solutions, we conducted a study of carbapenem-resistant Pseudomonas aeruginosa (CRPA) infections in a secondary care hospital setting. The study utilized the carbapenem inactivation method (CIM), a leading phenotypic analysis, to determine carbapenemase activity in 63 CRPA isolates. Additionally, polymerase chain reaction (PCR) analysis was conducted to test for the presence of carbapenemase genes associated with the production or expression of various carbapenemase enzymes, including blaKPC, blaNDM, blaVIM, blaOXA-48, blaIMP, and blaGES. Arbitrary primed PCR (AP-PCR) was performed to assess the clonal relationship between different isolates. The isolates were also classified as either health care-associated infections or community-acquired infections, and their clonal relationship and gene positivity were evaluated. A total of 63 CRPA samples underwent evaluation, with 14 isolates determined to be carbapenemase producers via CIM tests. PCR assays revealed that 14 isolates carried carbapenemase genes, with 9 carrying blaNDM, 2 carrying blaGES, 2 carrying blaVIM, and 1 carrying blaIMP. CRPA exhibited a 22% prevalence of carbapenemase genes, of which 64% were attributed to the NDM gene responsible for multidrug resistance. AP-PCR revealed high clonal diversity among the isolates. Molecular epidemiological evaluation also showed no dominant outbreak strain among PA isolates. This study presents significant data on the prevalence and distribution of carbapenemase-producing CRPA strains isolated from secondary health care facilities. Typically, the literature focuses on resistance rates in tertiary care public hospitals. These findings may aid in understanding resistance and its mechanisms, as well as in developing effective treatment strategies and infection control measures.

BACKGROUND

Reporting on the International Nosocomial Infection Control Consortium study results from 2015 to 2020, conducted in 630 intensive care units across 123 cities in 45 countries spanning Africa, Asia, Eastern Europe, Latin America, and the Middle East.

METHODS

Prospective intensive care unit patient data collected via International Nosocomial Infection Control Consortium Surveillance Online System. Centers for Disease Control and Prevention/National Health Care Safety Network definitions applied for device-associated health care-associated infections (DA-HAI).

RESULTS

We gathered data from 204,770 patients, 1,480,620 patient days, 936,976 central line (CL)-days, 637,850 mechanical ventilators (MV)-days, and 1,005,589 urinary catheter (UC)-days. Our results showed 4,270 CL-associated bloodstream infections, 7,635 ventilator-associated pneumonia, and 3,005 UC-associated urinary tract infections. The combined rates of DA-HAIs were 7.28%, and 10.07 DA-HAIs per 1,000 patient days. CL-associated bloodstream infections occurred at 4.55 per 1,000 CL-days, ventilator-associated pneumonias at 11.96 per 1,000 MV-days, and UC-associated urinary tract infections at 2.91 per 1,000 UC days. In terms of resistance, Pseudomonas aeruginosa showed 50.73% resistance to imipenem, 44.99% to ceftazidime, 37.95% to ciprofloxacin, and 34.05% to amikacin. Meanwhile, Klebsiella spp had resistance rates of 48.29% to imipenem, 72.03% to ceftazidime, 61.78% to ciprofloxacin, and 40.32% to amikacin. Coagulase-negative Staphylococci and Staphylococcus aureus displayed oxacillin resistance in 81.33% and 53.83% of cases, respectively.

CONCLUSIONS

The high rates of DA-HAI and bacterial resistance emphasize the ongoing need for continued efforts to control them.

Determinants of Healthcare-Associated Infections in King Abdulaziz Specialized Hospital in Taif, Saudi Arabia

BACKGROUND

Healthcare-associated infections (HAIs) represent a significant challenge in hospital settings, contributing to increased morbidity, mortality, and healthcare costs. This study aimed to estimate the prevalence and socio-demographic and clinical determinants of HAIs at the King Abdulaziz Specialized Hospital (KAASH) in Taif, Saudi Arabia.

METHODOLOGY

A hospital-based cross-sectional study was conducted from March 2023 to January 2024 targeting inpatients aged 18 and above in all units and wards. Data were collected using the National Healthcare Safety Network (NHSN) criteria for definitions of surveillance. A structured questionnaire gathered socio-demographic and clinical data from patients or next of kin if the patient was not fully oriented. Descriptive statistics were performed, and analytical methods used included Pearson chi-square test, Pearson correlation, independent t-test, and one-way analysis of variance.

RESULTS

Among 318 participants included in this study, the mean age of participants was 56.44 years, with a slight female predominance (n=164, 51.6%). Hypertension (n=162, 50.9%) and diabetes (n=126, 39.6%) were the most prevalent comorbidities. Pneumonia (n=60, 26.8%) and trauma (n=55, 17.4%) were the leading causes of admission. The two most common HAIs included catheter-associated urinary tract infections (CAUTI) (n=124, 39%) and central line-associated bloodstream infections (CLABSI) (n=74, 23.3%). The primary causative organisms were Klebsiella pneumoniae (n=96, 30.2%) and Acinetobacter baumannii (n=32, 10.1%). The most significant predictors of HAIs were as follows: For CLABSI, risk factors include having three or more comorbidities, fever above 37.8°C, chills or rigors, hypotension, and positive blood culture. For CAUTI, key predictors were urinary tract infection (UTI), positive urine culture, acute pain or swelling of the testes, suprapubic tenderness, visible hematuria, and leukocytosis. Significant predictors of bloodstream infections (BSI) include having a BSI, positive blood culture, chills or rigors, and hypotension. Fever and hypotension increased CLABSI and BSI risk but reduced the CAUTI risk.

CONCLUSION

The study highlights a significant burden of HAIs at the KAASH, with multiple predictors. The findings underscore the need for robust infection control measures and targeted interventions to reduce HAI incidence and improve patient outcomes.

The Global Burden of Sepsis and Septic Shock

A dysregulated host response to infection causes organ dysfunction in sepsis and septic shock, two potentially fatal diseases. They continue to be major worldwide health burdens with high rates of morbidity and mortality despite advancements in medical care. The goal of this thorough review was to present a thorough summary of the current body of knowledge about the prevalence of sepsis and septic shock worldwide. Using widely used computerized databases, a comprehensive search of the literature was carried out, and relevant studies were chosen in accordance with predetermined inclusion and exclusion criteria. A narrative technique was used to synthesize the data that were retrieved. The review's conclusions show how widely different locations and nations differ in terms of sepsis and septic shock's incidence, prevalence, and fatality rates. Compared to high-income countries (HICs), low- and middle-income countries (LMICs) are disproportionately burdened more heavily. We talk about risk factors, comorbidities, and difficulties in clinical management and diagnosis in a range of healthcare settings. The review highlights the need for more research, enhanced awareness, and context-specific interventions in order to successfully address the global burden of sepsis and septic shock.

Attributable Mortality for Pediatric and Neonatal Central Line-Associated Bloodstream Infections in Greece

Central line-associated bloodstream infections (CLABSIs) are the most frequent pediatric hospital-acquired infections and significantly impact outcomes. The aim of this study was to estimate the attributable mortality for CLABSIs in pediatric and neonatal patients in Greece. A retrospective matched-cohort study was performed, in two tertiary pediatric hospitals. Inpatients with a central line in neonatal and pediatric intensive care units (NICUs and PICUs), hematology/oncology units, and a bone marrow transplantation unit between June 2012 and June 2015 were eligible. Patients with confirmed CLABSI were enrolled on the day of the event and were matched (1:1) to non-CLABSI patients by hospital, hospitalization unit, and length of stay prior to study enrollment (188 children enrolled, 94 CLABSIs). Attributable mortality was estimated. During the study period, 22 patients with CLABSI and nine non-CLABSI patients died (23.4 vs. 9.6%, respectively, p  = 0.011), leading to an attributable mortality of 13.8% (95% confidence interval [CI] = 3.4-24.3%). Children in PICUs were more likely to die, presenting an attributable mortality of 20.2% (95% CI = - 1.4-41.8%), without reaching, however, statistical significance. After multiple logistic regression, patients with CLABSI were four times more likely to die (odds ratio [OR] = 4.29, 95% CI = 1.28-14.36, p  = 0.018). Survival analysis showed no difference in time to death after study enrollment between patients with CLABSI and non-CLABSI patients (log-rank p  = 0.137, overall median survival time = 7.8 months). Greek pediatric mortality rates are increased by the CLABSI occurrence, highlighting the importance of infection prevention strategies.

Epidemiology and microbiology of catheter-associated urinary tract infections: A 14-year surveillance study at a tertiary care center in Lebanon

BACKGROUND

Catheter-associated urinary tract infections (CAUTIs) are the most common device-associated healthcare-acquired infections and pose a significant burden on patients and healthcare systems worldwide. However, there is a paucity of data on CAUTI epidemiology and microbiology in the Middle East and North Africa (MENA) region, including Lebanon.

METHODS

This 14-year retrospective cohort study was conducted at a tertiary care center in Lebanon. It analyzed data on all adult patients diagnosed with CAUTI between January 2009 and December 2022 in intensive care units (ICUs) and between June 2011 and December 2022 in regular units. Incidence rates, urinary catheter utilization ratios, and microbiological profiles were collected and analyzed.

RESULTS

A total of 620 CAUTI cases were identified during the study period. The overall CAUTI rate was 2.4 per 1000 catheter-days, with higher rates in ICUs (3.2 per 1000 catheter-days) compared to regular units (1.4 per 1000 catheter-days). No significant changes in the rates were noted despite implementing many interventions. The most common pathogens were Gram-negative bacteria, with Escherichia coli, Pseudomonas aeruginosa, and Klebsiella pneumoniae being predominant. Multidrug-resistant organisms represented 48% of all isolates. Enterobacterales were largely extended-spectrum β-lactamase (ESBL) producing, and most Acinetobacter baumannii isolates showed multidrug resistance.

CONCLUSIONS

This study provides important insights into CAUTI epidemiology and microbiology in a tertiary care center in Lebanon, addressing the knowledge gap in this area in the MENA region. Despite implementing prevention measures, CAUTI rates remained stable over the 14-year period. The findings highlight the need for continuous improvement in infection prevention practices, diagnostic stewardship, and antimicrobial stewardship, especially given the rising threat of antimicrobial resistance. These results can serve as a guide for the development of targeted preventive strategies to reduce the burden of CAUTIs, particularly in low- and middle-income countries where antimicrobial resistance is a major issue.

Central venous catheter-related bloodstream infections: Epidemiology and risk factors for hematogenous complications

BACKGROUND

Central catheter-related bloodstream infections (CRBIs) can lead to severe complications, including suppurative thrombophlebitis, endocarditis, and metastatic infections. While complications due to CRBIs caused by Staphylococcus aureus (SA) are well-known, there are limited data regarding CRBIs caused by other bacteria.

METHODS

This 2-year retrospective single-center study of patients with CRBIs from a tertiary care hospital examined the hematogenous complications associated with CRBIs according to patient characteristics, central venous catheter (CVC) types, and causative bacteria.

RESULTS

All in all, 254 patients with confirmed CRBIs were included; 285 bacteria types were isolated, mainly Enterobacteriaceae (n = 94), coagulase-negative Staphylococci (CNS, n = 82), SA (n = 45), and non-fermenting Gram-negative bacteria (NGB, n = 45). Among the patients, 35 developed at least one hematogenous complication (14 %), including suppurative thrombophlebitis (n = 15), endocarditis (n = 7) and metastatic infections (n = 16). In multivariate analysis, hemodialysis, persistent bacteremia for at least 3 days, and CRBIs caused by SA were associated with increased risk for hematogenous complications, while previous curative anticoagulant treatment was associated with reduced risk. Diabetes, CVC maintenance, and hematogenous complications were associated with increased 3-month mortality.

CONCLUSION

A thorough investigation of hematogenous complications should be envisioned in patients with persistent bacteremia, particularly those with SA infections and those on hemodialysis.

Epidemiological patterns of bacterial and fungal healthcare-associated infection outbreaks in Ministry of Health hospitals in Saudi Arabia, 2020-2021

BACKGROUND

Healthcare-Associated Infections (HAI) outbreaks remain a huge challenge to the healthcare sectors worldwide. Their impact on morbidity and mortality, economic and healthcare burden remains a public health problem and a challenge to the HAI surveillance system, infection control, and HAI management strategies.

AIM

This study aimed to investigate the epidemiological patterns, distribution, causative agents of HAI outbreaks and the influence of age, COVID-19 co-infection, medical invasive procedures, and hospital units on mortality among HAI outbreaks cases.

METHODS

This chart review study involved HAI outbreak cases recorded in Ministry of Health hospitals during 2020-2021 in Saudi Arabia. HAI outbreak notification and investigation forms were used for data collection. A binary logistic regression model was performed to determine the significant predictors of mortality. Univariate analyses were performed to determine the association between hospital units, organisms, and COVID-19 co-infection to the site of infection.

RESULTS

A total of 217 HAI outbreaks with 1003 cases were recorded in 2020-2021. Gram-negative bacteria were isolated from 73.8% of the cases. The overall specific case fatality rate was 47.5%. The significant predictors of mortality were age, invasive medical procedures, COVID-19 co-infection, and intensive care units' admission. Moreover, ventilator-associated events were more associated with cases co-infected with COVID-19.

CONCLUSION

HAI outbreaks were most prevalent in the Western and Central region and in intensive care units. Gram negative bacteria were responsible for most of cases while ventilator-associated events and central line-associated bloodstream infections were the most common infection sites. Implementing targeted and effective prevention and control strategies is recommended.

Catheter-associated urinary tract infection (CAUTI) reduction in a neuroscience intensive care unit: A multidisciplinary approach

Utilizing a multidisciplinary approach to identify catheter-associated urinary tract infection (CAUTI) risks in Neuroscience intensive care patients admitted for aneurysmal subarachnoid hemorrhage, our CAUTI rate decreased from 5.903 per 1,000 catheter days (June 2020-June 2021) to 0.371 per 1,000 catheter days in our postintervention time period (July 2021-March 2023). A review of our clinical treatment guideline to optimize the timing of indwelling urinary catheters and medication management related to bowel regimens has resulted in a sustained CAUTI reduction, particularly in postaneurysmal subarachnoid hemorrhage patients in the Neuroscience intensive care unit.

Imaging in pulmonary infections of immunocompetent adult patients

Pneumonia is a clinical syndrome characterised by fever, cough and alveolar infiltration of purulent fluid, caused by infection with a microbial pathogen. It can be caused by infections with bacteria, viruses or fungi, but a causative organism is identified in less than half of cases. The most common type of pneumonia is community-acquired pneumonia, which is caused by infections acquired outside the hospital. Current guidelines for pneumonia diagnosis require imaging to confirm the clinical suspicion of pneumonia. Thus, imaging plays an important role in both the diagnosis and management of pneumonia, with each modality having specific advantages and limitations. Chest radiographs are commonly used but have limitations in terms of sensitivity and specificity. Lung ultrasound shows high sensitivity and specificity. Computed tomography scans offer higher diagnostic accuracy but involve higher radiation doses. Radiological patterns, including lobar, lobular and interstitial pneumonia, provide valuable insights into causative pathogens and treatment decisions. Understanding these radiological patterns is crucial for accurate diagnosis. In this review, we will summarise the most important aspects pertaining to the role of imaging in pneumonia and will highlight the imaging characteristics of the most common causative organisms.

Ventilator-Associated Pneumonia in the Neonatal Intensive Care Unit-Incidence and Strategies for Prevention

The second most prevalent healthcare-associated infection in neonatal intensive care units (NICUs) is ventilator-associated pneumonia (VAP). This review aims to update the knowledge regarding the incidence of neonatal VAP and to summarize possible strategies for prevention. The VAP incidence ranges from 1.4 to 7 episodes per 1000 ventilator days in developed countries and from 16.1 to 89 episodes per 1000 ventilator days in developing countries. This nosocomial infection is linked to higher rates of illness, death, and longer hospital stays, which imposes a substantial financial burden on both the healthcare system and families. Due to the complex nature of the pathophysiology of VAP, various approaches for its prevention in the neonatal intensive care unit have been suggested. There are two main categories of preventative measures: those that attempt to reduce infections in general (such as decontamination and hand hygiene) and those that target VAP in particular (such as VAP care bundles, head of bed elevation, and early extubation). Some of the interventions, including practicing good hand hygiene and feeding regimens, are easy to implement and have a significant impact. One of the measures that seems very promising and encompasses a lot of the preventive measures for VAP are the bundles. Some preventive measures still need to be studied.

Effects of the care given to intensive care patients using an evidence model on the prevention of central line-associated bloodstream infections

It is important to put evidence-based guidelines into practice in the prevention of central line-associated bloodstream infections in intensive care patients. In contrast to expensive and complex interventions, a care bundle that includes easy-to-implement and low-cost interventions improves clinical outcomes. The compliance of intensive care nurses with guidelines is of great importance in achieving these results. The Translating Evidence into Practice Model provides guidance in how to implement the necessary guidelines. This quasi-experimental study used a post-test control group design in nonequivalent groups and was conducted in the anesthesia intensive care unit of a tertiary-level training and research hospital. All patients who were hospitalized in the intensive care unit, who had a central line during the study, and who met the inclusion criteria were included in the sample. The care bundle comprised education, and protocols for hand hygiene and the aseptic technique, maximum sterile barrier precautions, central line insertion trolley, and management of nursing care. To analyze the data, the independent samples t-test, the Mann-Whitney U test, chi-square test, dependent samples t-test, rate ratio, and relative risk were used with 95% confidence intervals. The rate of central line-associated bloodstream infections was significantly lower in the intervention group (2.85/1000 central line days) than in the control group (3.35/1000 central line days) (P = 0.042). The number of accesses to the central line by the nurses decreased significantly in the intervention group compared to the control group (P < 0.001). The mean score for the nurses' evidence-based guideline post-education knowledge (70.80 ± 12.26) was significantly higher than that pre-education (48.20 ± 14.66) (P < 0.001). Compliance with the guideline recommendations in central line-related nursing interventions and in the central line insertion process was significantly better in the intervention group than in the control group in many interventions (P < 0.05). The mean score for the nurses' attitude towards evidence-based nursing increased significantly over time (59.87 ± 7.23 at the 0th month; 63.79 ± 7.24 at the 6th month) (P < 0.001). Nursing care given by implementing the central line care bundle with the Translating Evidence into Practice Model affected the measures. Thanks to the implementation of the care bundle, the rate of infections and the number of accesses to the central line decreased, while the critical care nurses' knowledge of evidence-based guidelines, compliance with the guideline recommendations in central line-related nursing interventions, and attitudes towards evidence-based nursing improved.

Promoting Patient Safety: Exploring Device-Associated Healthcare Infections and Antimicrobial Susceptibility Pattern in a Multidisciplinary Intensive Care Units

INTRODUCTION

Device-associated healthcare infections are among the prevailing threats to patient safety worldwide. They constitute the third most common adverse event during healthcare delivery, resulting in heightened morbidity, mortality, and healthcare costs. Patients in intensive care units (ICUs) are at increased risk for device-associated healthcare infections. Focused active surveillance is a crucial measure for assessing the prevalence of healthcare-associated infections and controlling the transmission of pathogens, ultimately contributing to the establishment of quality outcome indicators. This study aimed to investigate and establish the baseline rates of healthcare-associated infections associated with medical devices in adult multidisciplinary ICUs within a tertiary care institute.

MATERIAL AND METHODS

 This hospital-based prospective observational study was conducted in two adult ICUs of a tertiary care institute in Central India over nine months. Targeted active surveillance for three device-associated health care infections namely central line-associated bloodstream infection (CLABSI), catheter-associated urinary tract infection (CAUTI), and ventilator-associated event (VAE) was conducted as per the Center for Disease Control (CDC)/National Healthcare Safety Network (NHSN) 2016 surveillance definitions and criteria. Pathogens associated with device-associated healthcare infections were identified and their antimicrobial susceptibility profile was studied.

RESULTS

 During the study period, a total of 5,773 patient days were investigated. Of 1,270 patients, 28 episodes of device-associated healthcare infections were detected in 26 patients, this suggests a collective occurrence of five device-associated healthcare infections for every 1,000 patient days in the ICUs. The device utilization ratios of the central line, mechanical ventilator, and urinary catheters were 0.33, 0.27, and 0.68, respectively. VAE, CLABSI, and CAUTI rates were 8.92, 5.68, and 0.76 per 1,000 device days, respectively. The most common pathogen isolated from device-associated healthcare infections was Klebsiella pneumoniae (39%) followed by Acinetobacter baumanii (22%). The majority (82.3%) of pathogens were multidrug resistant. The death rate among device-associated healthcare infections was 69.2% with a crude excess mortality rate of 37.7%.

CONCLUSION

The study sheds light on the proportion, types of device-associated healthcare infections, and underlying etiological agents associated with these infections in our institute's ICUs, thereby facilitating a better understanding of the healthcare-associated infection landscape within our facility. Moreover, the susceptibility pattern of pathogens associated with these infections offers crucial information for guiding the selection of appropriate antimicrobial therapies and infection control measures.

Risk factors for neonatal VAP: A retrospective cohort study

Ventilator-associated pneumonia (VAP) is a serious complication in neonates requiring mechanical ventilation. This study aimed to determine the risk factors associated with the development of VAP in neonates admitted to the neonatal intensive care unit (NICU) of the Affiliated Hospital of Southwest Medical University. In a retrospective observational study, neonates admitted to the NICU from 1 January 2019, to 31 December 2021, requiring ventilation for more than 48 h were included. Neonates who died within 48 h of NICU admission, those without obtainable consent, or identified with a genetic syndrome were excluded. Various neonatal and clinical variables were evaluated. Univariate and multivariate analyses were performed to determine risk factors associated with VAP. Of the total neonates included, several risk factors were identified for VAP, such as being a premature infant and use of dexamethasone and sedatives. Moreover, reintubation was found to decrease the risk of VAP. Some factors like gestational age, birth weight, Apgar scores at 5 min, and other parameters were found not significantly associated with the development of VAP. The study identified several risk factors associated with the development of VAP in neonates. Recognizing these risk factors could help in the prevention and early management of VAP, thus improving the prognosis for these patients. Further studies are needed to validate these findings and explore the mechanistic links between these factors and VAP.

Molecular characterization and differential effects of levofloxacin and ciprofloxacin on the potential for developing quinolone resistance among clinical Pseudomonas aeruginosa isolates

Background

Fluoroquinolones are some of the most used antimicrobial agents for the treatment of Pseudomonas aeruginosa. This study aimed at exploring the differential activity of ciprofloxacin and levofloxacin on the selection of resistance among P. aeruginosa isolates at our medical center.

Methods

233 P. aeruginosa clinical isolates were included in this study. Antimicrobial susceptibility testing (AST) was done using disk diffusion and broth microdilution assays. Random Amplification of Polymorphic DNA (RAPD) was done to determine the genetic relatedness between the isolates. Induction of resistance against ciprofloxacin and levofloxacin was done on 19 isolates. Fitness cost assay was done on the 38 induced mutants and their parental isolates. Finally, whole genome sequencing was done on 16 induced mutants and their 8 parental isolates.

Results

AST results showed that aztreonam had the highest non-susceptibility. RAPD results identified 18 clusters. The 19 P. aeruginosa isolates that were induced against ciprofloxacin and levofloxacin yielded MICs ranging between 16 and 256 μg/mL. Levofloxacin required fewer passages in 10 isolates and the same number of passages in 9 isolates as compared to ciprofloxacin to reach their breakpoints. Fitness cost results showed that 12 and 10 induced mutants against ciprofloxacin and levofloxacin, respectively, had higher fitness cost when compared to their parental isolates. Whole genome sequencing results showed that resistance to ciprofloxacin and levofloxacin in sequenced mutants were mainly associated with alterations in gyrA, gyrB and parC genes.

Conclusion

Understanding resistance patterns and risk factors associated with infections is crucial to decrease the emerging threat of antimicrobial resistance.

Changes in the prevalence of pathogens causing hospital-acquired bacterial pneumonia and the impact of their antimicrobial resistance patterns on clinical outcomes: A propensity-score-matched study

BACKGROUND

This study aimed to evaluate changes in the prevalence of pathogens causing hospital-acquired bacterial pneumonia (HABP) and their antimicrobial resistance patterns in recent years, and to identify risk factors for 28-day all-cause mortality (ACM) in patients with HABP.

METHODS

A propensity-score-matched study was performed by randomly allocating patients with ventilator-associated and non-ventilator-associated bacterial pneumonia admitted to two university hospitals between 2011 and 2021.

RESULTS

In total, 17,250 patients with HABP were enrolled. The annual incidence of Staphylococcus aureus HABP decreased during the study period, while that of Klebsiella pneumoniae HABP increased significantly each year. Over the same period, the resistance rate of S. aureus to methicillin decreased from 88.4% to 64.4%, while the non-susceptibility rate of K. pneumoniae to carbapenems increased from 0% to 38%. HABP caused by A. baumannii [adjusted odds ratio (aOR) 1.50, 95% confidence interval (CI) 1.25-1.79], K. pneumoniae (aOR 1.28, 95% CI 1.16-1.40) and Stenotrophomonas maltophilia (aOR 1.32, 95% CI 1.05-1.66) was a risk factor for 28-day ACM. Patients with HABP caused by methicillin-resistant S. aureus and carbapenem-non-susceptible A. baumannii or K. pneumoniae had a significantly lower probability of survival. HABP with preceding coronavirus disease 2019 (COVID-19) was associated with high 28-day ACM (aOR 5.40, 955 CI 3.03-9.64) and high incidence of bacteraemic pneumonia (aOR 40.55, 95% CI 5.26-312.79).

CONCLUSIONS

This study showed shifting trends in HABP-causing pathogens in terms of annual incidence and resistance rates to major therapeutic antimicrobial agents. HABP-causing bacterial pathogens, their antimicrobial resistance phenotypes, and preceding COVID-19 were significantly associated with progression of HABP to bloodstream infection and 28-day ACM in infected patients.

A prospective surveillance study of healthcare-associated infections in an intensive care unit from a tertiary care teaching hospital from 2012-2019

Healthcare-associated infections (HAIs) continue to be the most common adverse event affecting critically ill inpatients in intensive care units (ICUs). Limited data exist in the English literature on the epidemiology of HAIs in ICUs from China. The purpose of this prospective study was to understand the prevalence and trends of HAIs in the ICU to guide clinicians to take effective prevention and control measures. In total, 20 ICU beds in the hospital from January 2012 to December 2019 were selected for surveillance. HAI diagnosis and device-associated infection surveillance were based on the criteria set forth by the original Ministry of Health of the People's Republic of China. The full-time staff for HAI management monitored all patients who stayed in the ICU > 48 hours during the study period and calculated the device utilization ratio and device-associated infection rate. The rate of HAIs and the adjusted rate were 18.78 per 1000 patient-days and 5.17 per 1000 patient-days, respectively. The rates of ventilator-associated pneumonias, catheter-associated urinary tract infections, and central line-associated bloodstream infections were 22.68 per 1000 device-days, 2.40 per 1000 device-days, and 2.27 per 1000 device-days, respectively. A total of 731 pathogenic bacteria were detected in the patients with HAIs. Gram-negative and gram-positive bacteria accounted for 67.44% and 16.83%, respectively. Continuous target monitoring, regular analysis of high-risk factors, and timely intervention measures could effectively reduce HAIs in the ICU. Additionally, these findings could be used for developing new strategies to prevent and control HAIs in ICUs.

Clinical Characteristics and Prognosis of Hospital-Acquired Klebsiella pneumoniae Bacteremic Pneumonia versus Escherichia coli Bacteremic Pneumonia: A Retrospective Comparative Study

Objective

This research aimed to investigate the variations in clinical features and prognosis of HABP caused by E. coli and K. pneumoniae. We also aimed to evaluate the risk variables related to 30-day death in the investigated groups.

Methods

A single-center retrospective cohort research lasting four years was performed. A total of 117 patients with HABP were involved in this research. The primary prognosis was 30-day death.

Results

Among 117 patients with HABP, 60 patients were infected with K. pneumoniae (KP-HABP), and 57 patients were infected with E. coli (E. coli-HABP). A higher proportion of males, ICU admission, undergoing tracheotomy and trachea cannulation, carbapenem-resistant strains, inappropriate empirical therapy (IET), immune compromise, diabetes mellitus, and sepsis were observed in the patients with KP-HABP (all P < 0.05). Meanwhile, the median SOFA score and Pitt score were significantly (P < 0.001) higher in the KP-HABP group compared to the E. coli-HABP group. The 30-day death was 48.33% in the KP-HABP group and 24.56% in the E. coli-HABP group (P = 0.008). After adjusting for the main covariates, the hazard ratios for 30-day mortality in KP-HABP were 1.58 (95% CI:0.80-3.12), 3.24 (95% CI:1.48-7.06), 5.67 (95% CI:2.00-16.07), and 5.99 (95% CI:2.10-17.06), respectively. Multivariate logistic regression models revealed that IET, hypoproteinaemia, cerebral vascular disease (CVD), and SOFA score ≥ 5.0 were the independent risk variables for 30-day death in KP-HABP. Simultaneously, SOFA score ≥ 4.0 and Pitt score ≥ 2.0 were independent risk factors for 30-day mortality in E. coli-HABP.

Conclusion

The clinical features of HABP vary depending on whether it is caused by Escherichia coli or K. pneumoniae. KP-HABP patients have higher 30-day mortality than E. coli-HABP patients. To ensure greater validity, it is necessary to further verify this conclusion using a larger sample size.

Risk factors for mortality over 18 years in 317 ICUs in 9 Asian countries: The impact of healthcare-associated infections

OBJECTIVE

To identify risk factors for mortality in intensive care units (ICUs) in Asia.

DESIGN

Prospective cohort study.

SETTING

The study included 317 ICUs of 96 hospitals in 44 cities in 9 countries of Asia: China, India, Malaysia, Mongolia, Nepal, Pakistan, Philippines, Sri Lanka, Thailand, and Vietnam.

PARTICIPANTS

Patients aged >18 years admitted to ICUs.

RESULTS

In total, 157,667 patients were followed during 957,517 patient days, and 8,157 HAIs occurred. In multiple logistic regression, the following variables were associated with an increased mortality risk: central-line-associated bloodstream infection (CLABSI; aOR, 2.36; P < .0001), ventilator-associated event (VAE; aOR, 1.51; P < .0001), catheter-associated urinary tract infection (CAUTI; aOR, 1.04; P < .0001), and female sex (aOR, 1.06; P < .0001). Older age increased mortality risk by 1% per year (aOR, 1.01; P < .0001). Length of stay (LOS) increased mortality risk by 1% per bed day (aOR, 1.01; P < .0001). Central-line days increased mortality risk by 2% per central-line day (aOR, 1.02; P < .0001). Urinary catheter days increased mortality risk by 4% per urinary catheter day (aOR, 1.04; P < .0001). The highest mortality risks were associated with mechanical ventilation utilization ratio (aOR, 12.48; P < .0001), upper middle-income country (aOR, 1.09; P = .033), surgical hospitalization (aOR, 2.17; P < .0001), pediatric oncology ICU (aOR, 9.90; P < .0001), and adult oncology ICU (aOR, 4.52; P < .0001). Patients at university hospitals had the lowest mortality risk (aOR, 0.61; P < .0001).

CONCLUSIONS

Some variables associated with an increased mortality risk are unlikely to change, such as age, sex, national economy, hospitalization type, and ICU type. Some other variables can be modified, such as LOS, central-line use, urinary catheter use, and mechanical ventilation as well as and acquisition of CLABSI, VAE, or CAUTI. To reduce mortality risk, we shall focus on strategies to reduce LOS; strategies to reduce central-line, urinary catheter, and mechanical ventilation use; and HAI prevention recommendations.

Prediction of Catheter-Associated Urinary Tract Infections Among Neurosurgical Intensive Care Patients: A Decision Tree Analysis

BACKGROUND

Catheter-associated urinary tract infections (CAUTIs) are the most common device-associated infections in hospitals and can be prevented. To identify the risk factors and develop a risk prediction model for CAUTIs among neurosurgical intensive care unit (NICU) patients.

METHODS

All patients admitted to the NICU of a tertiary hospital between January 2019 and January 2020 were enrolled. Two decision tree models were applied to analyze the risk factors associated with CAUTIs in NICU patients. The performance of the decision tree model was evaluated.

RESULTS

A total of 537 patients admitted to the NICU with indwelling catheters were recruited for this study. The rate of CAUTIs was 4.44 per 1000 catheter days, and Escherichia coli was the predominant pathogen causing CAUTIs among indwelling catheter patients. The classification and regression tree model displayed good power of prediction (area under the curve : 0.920). Nine CAUTI risk factors (age ≥60 years (P = 0.004), Glasgow Coma Scale score ≤8 (P = 0.009), epilepsy at admission (P = 0.007), admission to the hospital during the summer (P < 0.001), ventilators use (P = 0.007), receiving less than 2 types of antibiotics (P < 0.001), albumin level <35 g/L (P = 0.002), female gender (P = 0.002), and having an indwelling catheter for 7-14 days (P = 0.001) were also identified.

CONCLUSION

We developed a novel scoring model for predicting the risk of CAUTIs in patients with neuro-critical illness in daily clinical practice. This model identified several risk factors for CAUTI among NICU patients, novel factors including epilepsy and admission during the summer, can be used to help providers prevent and reduce the risk of CAUTI among vulnerable groups.

Multinational prospective cohort study of rates and risk factors for ventilator-associated pneumonia over 24 years in 42 countries of Asia, Africa, Eastern Europe, Latin America, and the Middle East: Findings of the International Nosocomial Infection Control Consortium (INICC)

OBJECTIVE

Rates of ventilator-associated pneumonia (VAP) in low- and middle-income countries (LMIC) are several times above those of high-income countries. The objective of this study was to identify risk factors (RFs) for VAP cases in ICUs of LMICs.

DESIGN

Prospective cohort study.

SETTING

This study was conducted across 743 ICUs of 282 hospitals in 144 cities in 42 Asian, African, European, Latin American, and Middle Eastern countries.

PARTICIPANTS

The study included patients admitted to ICUs across 24 years.

RESULTS

In total, 289,643 patients were followed during 1,951,405 patient days and acquired 8,236 VAPs. We analyzed 10 independent variables. Multiple logistic regression identified the following independent VAP RFs: male sex (adjusted odds ratio [aOR], 1.22; 95% confidence interval [CI], 1.16-1.28; P < .0001); longer length of stay (LOS), which increased the risk 7% per day (aOR, 1.07; 95% CI, 1.07-1.08; P < .0001); mechanical ventilation (MV) utilization ratio (aOR, 1.27; 95% CI, 1.23-1.31; P < .0001); continuous positive airway pressure (CPAP), which was associated with the highest risk (aOR, 13.38; 95% CI, 11.57-15.48; P < .0001); tracheostomy connected to a MV, which was associated with the next-highest risk (aOR, 8.31; 95% CI, 7.21-9.58; P < .0001); endotracheal tube connected to a MV (aOR, 6.76; 95% CI, 6.34-7.21; P < .0001); surgical hospitalization (aOR, 1.23; 95% CI, 1.17-1.29; P < .0001); admission to a public hospital (aOR, 1.59; 95% CI, 1.35-1.86; P < .0001); middle-income country (aOR, 1.22; 95% CI, 15-1.29; P < .0001); admission to an adult-oncology ICU, which was associated with the highest risk (aOR, 4.05; 95% CI, 3.22-5.09; P < .0001), admission to a neurologic ICU, which was associated with the next-highest risk (aOR, 2.48; 95% CI, 1.78-3.45; P < .0001); and admission to a respiratory ICU (aOR, 2.35; 95% CI, 1.79-3.07; P < .0001). Admission to a coronary ICU showed the lowest risk (aOR, 0.63; 95% CI, 0.51-0.77; P < .0001).

CONCLUSIONS

Some identified VAP RFs are unlikely to change: sex, hospitalization type, ICU type, facility ownership, and country income level. Based on our results, we recommend focusing on strategies to reduce LOS, to reduce the MV utilization ratio, to limit CPAP use and implementing a set of evidence-based VAP prevention recommendations.

Extensive spinal epidural abscess caused by Staphylococcus epidermidis: A case report and literature review

Background

Extensive spinal epidural abscess (SEA) is an exceptional and threatening condition that requires prompt recognition and proper management to avoid potentially disastrous complications. We aimed to find key elements of early diagnosis and rational treatments for extensive SEA.

Case presentation

A 70-year-old man complained of intense pain in the cervical-thoracic-lumbar spine that radiated to the lower extremity. Laboratory test results revealed a marked increase in all indicators of infection. The spinal magnetic resonance imaging (MRI) revealed a ventral SEA extending from C2 to L4. Owing to the patient's critical condition, laminectomy, drainage, and systemic antibiotic therapy were administered. And the multidrug-resistant Staphylococcus epidermidis was detected in the purulent material from this abscess.

Results

Postoperative MRI revealed diminished epidural abscess, and the clinical symptoms were dramatically and gradually relieved after two rounds of surgery and systemic antibiotic therapy involving the combination of ceftriaxone, linezolid, and rifampicin.

Conclusions

A comprehensive emergency assessment based on neck or back pain, neurological dysfunctions, signs of systemic infection, and MRI are important for early diagnosis of extensive SEA. Further, the combination of laminectomy, drainage, and systemic antibiotic therapy may be a rational treatment choice for patients with SEA, especially for extensive abscess or progressive neurological dysfunction.

Clinical predictors of mortality in patients with pseudomonas aeruginosa infection

BACKGROUND

Infections caused by Pseudomonas aeruginosa are difficult to treat with a significant cost and burden. In Lebanon, P. aeruginosa is one of the most common organisms in ventilator-associated pneumonia (VAP). P. aeruginosa has developed widespread resistance to multiple antimicrobial agents such as fluoroquinolones and carbapenems. We aimed at identifying risk factors associated for P. aeruginosa infections as well as identifying independent risk factors for developing septic shock and in-hospital mortality.

METHODS

We used a cross-sectional study design where we included patients with documented P. aeruginosa cultures who developed an infection after obtaining written consent. Two multivariable regression models were used to determine independent predictors of septic shock and mortality.

RESULTS

During the observed period of 30 months 196 patients were recruited. The most common predisposing factor was antibiotic use for more than 48 hours within 30 days (55%). The prevalence of multi-drug resistant (MDR) P. aeruginosa was 10%. The strongest predictors of mortality were steroid use (aOR = 3.4), respiratory failure (aOR = 7.3), identified respiratory cultures (aOR = 6.0), malignancy (aOR = 9.8), septic shock (aOR = 18.6), and hemodialysis (aOR = 30.9).

CONCLUSION

Understanding resistance patterns and risk factors associated with mortality is crucial to personalize treatment based on risk level and to decrease the emerging threat of antimicrobial resistance.

Effectiveness of enhanced check during acute phase to reduce central venous catheters-associated bloodstream infections: a before-after, real-world study

BACKGROUND

To evaluate the effectiveness of enhanced check to the duration of the central venous catheters associated bloodstream infections (CABSIs), and the impact on infection rates.

METHODS

A before-after, real-world study in six adult intensive care units was conducted. All adult patients who had only one central venous catheter were included during two consecutive periods. The intervention period, added cross-check that all patients with central venous catheter (CVC) need to be performed, and included nurses' checks for insertion practices and doctors' checks for maintenance practices. Propensity scores matching were used to account for potential confounding, and restricted cubic spline was served as visualizing the CABSI risk.

RESULTS

A total of 2906 patients with 26,157 CVC-days were analyzed. After intervention, the density incidence of CABSI decreased from 10.24 to 6.33/1,000 CVC-days (P < 0.001), and the acute period of rapid increase in CABSI risk was shortened, 6.5 to 5 days for femoral-vein catheterization and 7 to 5.5 days for subclavian-vein catheterization. For jugular-vein catheterization, the acute onset period disappeared.

CONCLUSION

Enhanced check during the first 7 calendar days after CVC insertion shortens the duration of the CABSI acute phase and tends to decrease CABSI rate.

Risk factors for mortality in ICU patients in 10 middle eastern countries: The role of healthcare-associated infections

PURPOSE

The International Nosocomial Infection Control Consortium (INICC) found a high mortality rate in ICUs of the Middle East (ME). Our goal was to identify mortality risk factor (RF) in ICUs of the ME.

MATERIALS

From 08/01/2003 to 02/12/2022, we conducted a prospective cohort study in 236 ICUs of 77 hospitals in 44 cities in 10 countries of ME. We analyzed 16 independent variables using multiple logistic regression.

RESULTS

66,440 patients, hospitalized during 652,167 patient-days, and 13,974 died. We identified following mortality RF: Age (adjusted odds ratio (aOR):1.02;p < 0.0001) rising risk 2% yearly; length of stay (LOS) (aOR:1.02;p < 0.0001) rising the risk 2% per day; central line (CL)-days (aOR:1.01;p < 0.0001) rising risk 1% per day; mechanicalventilator (MV) utilization-ratio (aOR:14.51;p < 0.0001); CL-associated bloodstream infection (CLABSI) acquisition (aOR):1.49;p < 0.0001); ventilator-associated pneumonia (VAP) acquisition (aOR:1.50;p < 0.0001); female gender (OR:1.14;p < 0.0001); hospitalization at a public-hospital (OR:1.31;p < 0.0001); and medical-hospitalization (aOR:1.64;p < 0.0001). High-income countries showed lowest risk (aOR:0.59;p < 0.0001).

CONCLUSION

Some identified RF are unlikely to change, such as country income-level, facility ownership, hospitalization type, gender, and age. Some can be modified; LOS, CL-use, MV-use, CLABSI, VAP. So, to lower the mortality risk in ICUs, we recommend focusing on strategies to shorten the LOS, reduce CL and MV-utilization, and use evidence-based recommendations to prevent CLABSI and VAP.

The Epidemiology of Healthcare-Associated Bloodstream Infection in an Adult Intensive Care Unit: A Retrospective Cohort Study in a Single Tertiary Care Hospital in Hanoi, Vietnam

Background Healthcare-associated infections (HAIs), including bloodstream infections (BSIs) in the intensive care unit (ICU), are growing global public health problems. While high-income countries have reported the burden of HAIs precisely, low- and middle-income countries (LMICs), including Vietnam, often lack surveillance systems for HAIs. In Vietnam, few reports described HAI-associated BSIs. Therefore, in this study, we aim to clarify the characteristics of HAI-associated BSI in an adult ICU. Materials and methods We conducted a retrospective cohort study of HAI-associated BSI in the adult ICU of Bach Mai Hospital (BMH), Vietnam, between December 2013 and August 2015. For every case identified with bacteremia, we collected characteristics and laboratory findings of the case and followed the length of hospital stay and seven-day and 30-day survival. Predictors of 30-day mortality were analyzed using univariate and multivariate analyses. Results Among the 90 cases identified, the median age of the study cohort was 57 (range: 18-90) years, and 59 (65.6%) were male. Chronic heart disease was the most frequent comorbidity (n = 26, 28.9%). The pathogens isolated were mostly Candida spp. (n = 26, 26.3%) and Enterococcus spp. (n = 19, 19.2%). Among the 90 patients with confirmed HAI-associated BSI, 34 (37.8%) patients survived, while 31 (34.4%) patients died in 30 days. In multivariate analysis, chronic heart disease tended to increase with 30-day all-cause mortality (odds ratio (OR) = 3.5, 95% confidence interval (CI) = 1.0-11.9, p = 0.051). Conclusions Our retrospective cohort study is the largest investigation to describe HAI-associated BSI in an adult ICU in a tertiary care hospital in Vietnam. Improved laboratory detection and infection surveillance systems are needed to reduce HAI-associated BSI.

Multinational Prospective Cohort Study of Mortality Risk Factors in 198 ICUs of 12 Latin American Countries over 24 Years: The Effects of Healthcare-Associated Infections

BACKGROUND

The International Nosocomial Infection Control Consortium (INICC) has found a high ICU mortality rate in Latin America.

METHODS

A prospective cohort study in 198 ICUs of 96 hospitals in 46 cities in 12 Latin American countries to identify mortality risk factors (RF), and data were analyzed using multiple logistic regression.

RESULTS

Between 07/01/1998 and 02/12/2022, 71,685 patients, followed during 652,167 patient-days, acquired 4700 HAIs, and 10,890 died. We prospectively collected data of 16 variables. Following 11 independent mortality RFs were identified in multiple logistic regression: ventilator-associated pneumonia (VAP) acquisition (adjusted odds ratio [aOR] = 1.17; 95% CI: 1.06-1.30; p < 0.0001); catheter-associated urinary tract infection (CAUTI) acquisition (aOR = 1.34; 95% CI: 1.15-1.56; p < 0.0001); older age, rising risk 2% yearly (aOR = 1.02; 95% CI: 1.01-1.02; p < 0.0001); longer indwelling central line(CL)-days, rising risk 3% daily (aOR = 1.03; 95% CI: 1.02-1.03; p < 0.0001); longer indwelling urinary catheter(UC)-days, rising risk 1% daily (aOR = 1.01; 95% CI: 1.01-1.26; p < 0.0001); higher mechanical ventilation (MV) (aOR = 6.47; 95% CI: 5.96-7.03; p < 0.0001) and urinary catheter-utilization ratio (aOR = 1.19; 95% CI: 1.11-1.27; p < 0.0001); lower-middle level income country (aOR = 2.94; 95% CI: 2.10-4.12; p < 0.0001); private (aOR = 1.50; 95% CI: 1.27-1.77; p < 0.0001) or public hospital (aOR = 1.47; 95% CI: 1.24-1.74; p < 0.0001) compared with university hospitals; medical hospitalization instead of surgical (aOR = 1.67; 95% CI: 1.59-1.75; p < 0.0001); neurologic ICU (aOR = 4.48; 95% CI: 2.68-7.50; p < 0.0001); adult oncology ICU (aOR = 3.48; 95% CI: 2.14-5.65; p < 0.0001); and others.

CONCLUSION

Some of the identified mortality RFs are unlikely to change, such as the income level of the country, facility ownership, hospitalization type, ICU type, and age. But some of the mortality RFs we found can be changed, and efforts should be made to reduce CL-days, UC-days, MV-utilization ratio, UC-utilization ratio, and lower VAPs and CAUTI rates.

The Impact of Healthcare-Associated Infections on Mortality in ICU: A Prospective Study in Asia, Eastern Europe, Latin America, and the Middle East

BACKGROUND

The International Nosocomial Infection Control Consortium has found a high ICU mortality rate. Our aim was to identify all-cause mortality risk factors in ICU-patients.

METHODS

Multinational, multicenter, prospective cohort study at 786 ICUs of 312 hospitals in 147 cities in 37 Latin American, Asian, African, Middle Eastern, and European countries.

RESULTS

Between 07/01/1998 and 02/12/2022, 300,827 patients, followed during 2,167,397 patient-days, acquired 21,371 HAIs. Following mortality risk factors were identified in multiple logistic regression: Central line-associated bloodstream infection (CLABSI) (aOR:1.84; p<0.0001); ventilator-associated pneumonia (VAP) (aOR:1.48; p<0.0001); catheter-associated urinary tract infection (CAUTI) (aOR:1.18;p<0.0001); medical hospitalization (aOR:1.81; p<0.0001); length of stay (LOS), risk rises 1% per day (aOR:1.01; p<0.0001); female gender (aOR:1.09; p<0.0001); age (aOR:1.012; p<0.0001); central line-days, risk rises 2% per day (aOR:1.02; p<0.0001); and mechanical ventilator (MV)-utilization ratio (aOR:10.46; p<0.0001). Coronary ICU showed the lowest risk for mortality (aOR: 0.34;p<0.0001).

CONCLUSION

Some identified risk factors are unlikely to change, such as country income-level, facility ownership, hospitalization type, gender, and age. Some can be modified; CLABSI, VAP, CAUTI, LOS, and MV-utilization. So, to lower the risk of death in ICUs, we recommend focusing on strategies to shorten the LOS, reduce MV-utilization, and use evidence-based recommendations to prevent HAIs.

Frailty and Neutrophil Lymphocyte Ratio as Predictors of Mortality in Patients with Catheter-Associated Urinary Tract Infections or Central Line-Associated Bloodstream Infections in the Neurosurgical Intensive Care Unit: Insights from a Retrospective Study in a Developing Country

OBJECTIVE

We aim to evaluate the role of frailty and inflammatory markers in predicting the short-term outcomes after catheter-associated urinary tract infections (CAUTI) and central line-associated bloodstream infections (CLABSI).

METHODS

Data regarding the patients' characteristics, isolates on CAUTI and CLABSI, antibiotic susceptibility, frailty (11-point Modified Frailty Index), and inflammatory markers were retrospectively collected. Their impact on the short-term outcomes was assessed using regression modeling response.

RESULTS

One hundred and one patients with CAUTI (n = 71) and CLABSI (n = 30) between January 2018 and December 2019 were included in this study. The pooled incidence rates for CAUTI were 5.50 and for CLABSI 3.58 episodes/1000 catheter-days. We observed 74.7% drug resistance in our CAUTI isolates and 93.3% in CLABSI. In the multivariate analysis, frailty (P = 0.006), neutrophil/lymphocyte ratio (NLR) (P = 0.007) and the presence of sepsis (P = 0.029) were found to be significant predictors of in-hospital mortality in CAUTI. In patients with CLABSI, frailty (P = 0.029) and NLR (P = 0.029) were found significant and along with sepsis (P = 0.069) resulted in a regression model with good accuracy in predicting mortality. The receiver operating characteristic curve showed that 11-point Modified Frailty Index and NLR as well as the regression model significantly predicted mortality with an area under the curve of 86.1%, 81.4%, and 95.4%, respectively, in CAUTI, and 70.9%, 77.8%, and 95.2%, respectively, in CLABSI.

Pseudomonas aeruginosa Pneumonia: Evolution of Antimicrobial Resistance and Implications for Therapy

Pseudomonas aeruginosa (PA), a non-lactose-fermenting gram-negative bacillus, is a common cause of nosocomial infections in critically ill or debilitated patients, particularly ventilator-associated pneumonia (VAP), and infections of urinary tract, intra-abdominal, wounds, skin/soft tissue, and bloodstream. PA rarely affects healthy individuals, but may cause serious infections in patients with chronic structural lung disease, comorbidities, advanced age, impaired immune defenses, or with medical devices (e.g., urinary or intravascular catheters, foreign bodies). Treatment of pseudomonal infections is difficult, as PA is intrinsically resistant to multiple antimicrobials, and may acquire new resistance determinants even while on antimicrobial therapy. Mortality associated with pseudomonal VAP or bacteremias is high (> 35%) and optimal therapy is controversial. Over the past three decades, antimicrobial resistance (AMR) among PA has escalated globally, via dissemination of several international multidrug resistant "epidemic" clones. We discuss the importance of PA as a cause of pneumonia including health care-associated pneumonia, hospital-acquired pneumonia, VAP, the emergence of AMR to this pathogen, and approaches to therapy (both empirical and definitive).

Clinical and microbiological outcomes, by causative pathogen, in the ASPECT-NP randomized, controlled, Phase 3 trial comparing ceftolozane/tazobactam and meropenem for treatment of hospital-acquired/ventilator-associated bacterial pneumonia

OBJECTIVES

In the ASPECT-NP trial, ceftolozane/tazobactam was non-inferior to meropenem for treating nosocomial pneumonia; efficacy outcomes by causative pathogen were to be evaluated.

METHODS

Mechanically ventilated participants with hospital-acquired/ventilator-associated bacterial pneumonia were randomized to 3 g ceftolozane/tazobactam (2 g ceftolozane/1 g tazobactam) q8h or 1 g meropenem q8h. Lower respiratory tract (LRT) cultures were obtained ≤36 h before first dose; pathogen identification and susceptibility were confirmed at a central laboratory. Prospective secondary per-pathogen endpoints included 28 day all-cause mortality (ACM), and clinical and microbiological response at test of cure (7-14 days after the end of therapy) in the microbiological ITT (mITT) population.

RESULTS

The mITT population comprised 511 participants (264 ceftolozane/tazobactam, 247 meropenem). Baseline LRT pathogens included Klebsiella pneumoniae (34.6%), Pseudomonas aeruginosa (25.0%) and Escherichia coli (18.2%). Among baseline Enterobacterales isolates, 171/456 (37.5%) were ESBL positive. For Gram-negative baseline LRT pathogens, susceptibility rates were 87.0% for ceftolozane/tazobactam and 93.3% for meropenem. For Gram-negative pathogens, 28 day ACM [52/259 (20.1%) and 62/240 (25.8%)], clinical cure rates [157/259 (60.6%) and 137/240 (57.1%)] and microbiological eradication rates [189/259 (73.0%) and 163/240 (67.9%)] were comparable with ceftolozane/tazobactam and meropenem, respectively. Per-pathogen microbiological eradication for Enterobacterales [145/195 (74.4%) and 129/185 (69.7%); 95% CI: -4.37 to 13.58], ESBL-producing Enterobacterales [56/84 (66.7%) and 52/73 (71.2%); 95% CI: -18.56 to 9.93] and P. aeruginosa [47/63 (74.6%) and 41/65 (63.1%); 95% CI: -4.51 to 19.38], respectively, were also comparable.

CONCLUSIONS

In mechanically ventilated participants with nosocomial pneumonia owing to Gram-negative pathogens, ceftolozane/tazobactam was comparable with meropenem for per-pathogen 28 day ACM and clinical and microbiological response.

Device-Associated Hospital-Acquired Infections: Does Active Surveillance With Bundle Care Offer a Pathway to Minimize Them?

Background and objective The prevalence of hospital-acquired infections (HAIs) is underreported in developing nations due to a lack of systematic active surveillance. This study reports the burden of device-associated HAIs (DA-HAIs) based on two years of active surveillance with in situ bundle care in closed intensive care units (ICUs) of a tertiary care hospital. Materials and methods A prospective surveillance study was carried out in 140-bedded ICUs (2,100-bed hospital) of a tertiary care private medical college hospital. Daily active surveillance for catheter-associated urinary tract infection (CAUTI), ventilator-associated event (VAE), and central line-associated bloodstream infection (CLABSI) was done by trained infection control nurses (ICNs) along with quality champion nurses with HAI surveillance forms with bundle care auditing, which was attached to the case sheets of all patients on devices. The surveillance definitions of DA-HAIs were adapted from the Centers for Disease Control and Prevention (CDC)'s National Healthcare Safety Network (CDC-NHSN) 2017 surveillance criteria. Data were analyzed at the end of every month to generate the cumulative device-associated infection (DAI) rates and device utilization ratio (DUR). These data were compared with NHSN and International Nosocomial Infection Control Consortium (INICC) - India HAI rates and communicated to corresponding ICUs and also presented at the hospital infection control committee (HICC) meeting. Results The surveillance data were reported over 71,877 patient days during the study period. The DUR of urinary catheters, ventilator, and central line were 0.53, 0.16, and 0.22, respectively. CAUTI, VAE, and CLABSI rates were 0.97, 10.5, and 0.43 per 1,000 device days, respectively. Among 166 DA-HAIs reported, 182 pathogens were identified. Klebsiella pneumoniae was the most common organism isolated, accounting for 37.4% of all DA-HAI cases, followed by Acinetobacter baumanii (30.8%). Most of the Gram-negative organisms were carbapenem-resistant (153/175; 87.4%). Vancomycin resistance rate in Enterococcus was 28.5% (2/7). Conclusion DUR and CAUTI, VAE, CLABSI rates were less/on par with the benchmarks of INICC and CDC-NHSN in almost all ICUs of our tertiary care unit. Gram-negative pathogen with 87.4% carbapenem resistance worsened the scenario. Proper active surveillance with bundle care and training by ICNs made a significant difference in all DA-HAI rates, especially VAE, which decreased to 10.5 from 23.6 per 1,000 ventilator days. Sustained active surveillance of HAI and bundle care auditing by a trained infection prevention team with a stringent antibiotic policy are the need of the hour to combat DAIs.

Major bacterial isolate and antibiotic resistance from routine clinical samples in Southern Ethiopia

Currently, antibiotic-resistant bacterial infections are a challenge for the health care system. Although physicians demand timely drug resistance data to guide empirical treatment, local data is rather scarce. Hence, this study performed a retrospective analysis of microbiological findings at the Hawassa public hospital. Secondary data were retrieved to assess the prevalence and level of drug resistance for the most common bacterial isolates from clinical samples processed at Hawassa University Comprehensive Specialized Hospital. Out of 1085 clinical samples processed in the microbiology laboratory, the prevalence of bacterial infection was 32.6%. Bacterial bloodstream infection was higher in children than in adults (OR, 4; 95% CI 1.8-14.6; p = 0.005). E. coli and K. pneumoniae were the commonest bacterial isolate both in children (36.8%, 26.3%) and in adults (33.3%, 26.7%) from the urine sample while, the leading bacteria identified from the CSF sample was P. aeruginosa, 37% in children and 43% in adult. In this study, all identified bacterial isolates were multi-drug resistant (MDR) ranging from 50 to 91%. The highest proportion of MDR was S. aureus 91.1 followed by K. pneumoniae 87.6%. Since the nationwide investigation of bacterial isolate, and drug resistance is rare in Ethiopia, a report from such type of local surveillance is highly useful to guide empirical therapy by providing awareness on the level resistance of isolates.

Morbidity, mortality, and emerging drug resistance in Device-associated infections (DAIs) in intensive care patients at a 1000-bedded tertiary care teaching hospital

Background

Device-associated infections (DAIs) such as ventilator associated pneumonia (VAP), central line-associated blood stream infection (CLABSI), and catheter-related urinary tract infection (CAUTI) are principal contributors to health hazard and a major preventable threat to patient safety. Robust surveillance of DAI delineates infections, pathogens, resistograms, and facilitates antimicrobial therapy, infection-control, antimicrobial stewardship, and improvement in quality of care.

Methods

This prospective outcome surveillance study was conducted amongst 2067 ICU patients in a 1000-bedded teaching hospital. Clinical, laboratory, and environmental surveillance, as well as screening of health care professionals (HCPs) were conducted using the modified US Centers for Disease Control and Prevention-National Healthcare Safety Network definitions and methods. Morbidity, mortality, and health-care indices were analyzed and two-tier infection prevention and control was promulgated.

Results

Mean occupancy was 95.34% for 2061 patients of 7381 patients/bed/ICU days. One hundred seventeen episodes of DAI occurred in 1258 patients of 12,882 device-days with mean device utilization ratio of 1.79. Mean rate of DAI was 7.40 per 1000 device days. Multiresistant Pseudomonas aeruginosa was most commonly followed by Acinetobacter. Mean all-cause mortality in ICU was 24.85%, whereas all-cause mortality after DAI was 9.79%. Methicillin-resistant Staphylococcus aureus prevalence was 38.46% amongst health-care professionals.

Conclusion

Mean rates of VAP, CLABSI, and CAUTI were 20.69, 2.53, and 2.23 per 1000 device days comparable with Indian and global ICUs. Resolute conviction and sustained momentum in infection prevention and control is an essential step toward patient safety.

International Nosocomial Infection Control Consortium (INICC) report, data summary of 45 countries for 2013-2018, Adult and Pediatric Units, Device-associated Module

BACKGROUND

We report the results of INICC surveillance study from 2013 to 2018, in 664 intensive care units (ICUs) in 133 cities, of 45 countries, from Latin-America, Europe, Africa, Eastern-Mediterranean, Southeast-Asia, and Western-Pacific.

METHODS

Prospective data from patients hospitalized in ICUs were collected through INICC Surveillance Online System. CDC-NHSN definitions for device-associated healthcare-associated infection (DA-HAI) were applied.

RESULTS

We collected data from 428,847 patients, for an aggregate of 2,815,402 bed-days, 1,468,216 central line (CL)-days, 1,053,330 mechanical ventilator (MV)-days, 1,740,776 urinary catheter (UC)-days. We found 7,785 CL-associated bloodstream infections (CLAB), 12,085 ventilator-associated events (VAE), and 5,509 UC-associated urinary tract infections (CAUTI). Pooled DA-HAI rates were 5.91% and 9.01 DA-HAIs/1,000 bed-days. Pooled CLAB rate was 5.30/1,000 CL-days; VAE rate was 11.47/1,000 MV-days, and CAUTI rate was 3.16/1,000 UC-days. P aeruginosa was non-susceptible (NS) to imipenem in 52.72% of cases; to colistin in 10.38%; to ceftazidime in 50%; to ciprofloxacin in 40.28%; and to amikacin in 34.05%. Klebsiella spp was NS to imipenem in 49.16%; to ceftazidime in 78.01%; to ciprofloxacin in 66.26%; and to amikacin in 42.45%. coagulase-negative Staphylococci and S aureus were NS to oxacillin in 91.44% and 56.03%, respectively. Enterococcus spp was NS to vancomycin in 42.31% of the cases.

CONCLUSIONS

DA-HAI rates and bacterial resistance are high and continuous efforts are needed to reduce them.

Trends in Hospital-Acquired and Ventilator-Associated Bacterial Pneumonia Trials

BACKGROUND

New drug development for hospital-acquired bacterial pneumonia (HABP) and ventilator-associated bacterial pneumonia (VABP) is critical. Challenges remain in the conduct of HABP/VABP trials, especially in the contexts of enrollment, endpoints, nonstudy antibacterial drug therapy, and antimicrobial resistance.

METHODS

Four Phase 3 noninferiority trials (n = 2433 participants) submitted to the Food and Drug Administration after 2015 were analyzed for enrollment statistics, participant characteristics associated with 28-day all-cause mortality (ACM), microbiology, and receipt of nonstudy antibacterial drugs. All trials primarily enrolled patients with gram-negative bacterial infections.

RESULTS

The mean trial length was 2.7 years and the mean recruitment rate was 0.17 participants/site/month. ACM at 28 days was 17.1% and was higher among participants diagnosed with ventilated HABP (31.9%) or VABP (19.0%) than nonventilated HABP (9.9%). VABP participants tended to be younger, less likely to have chronic obstructive pulmonary disease, and more likely to have previously sustained an injury. Age, South American residence, diagnosis of ventilated HABP or VABP, and Acinetobacter baumannii infection were all associated with 28-day ACM in a multivariate logistic regression model. Infection by A. baumannii was most common in Eastern European and Asia/Pacific participants, and Eastern European isolates exhibited the highest levels of meropenem resistance. Concomitant nonstudy antibacterial drug therapy most commonly included beta-lactams and was initiated earliest in Western Europe.

CONCLUSION

This analysis of recent trials may assist in trial considerations for HABP/VABP development programs and promote needed antibacterial drug development for patients with serious infections.

Prevention of Central Line-Associated Bloodstream Infections Through Educational Interventions in Adult Intensive Care Units: A Systematic Review

Central line-associated bloodstream infections (CLABSIs) represent a severe systemic threat to patients admitted in ICUs and contribute to increased mortality, prolonged length of stay in ICUs, and increased costs. The majority of CLABSIs are preventable. The current systematic review aimed to investigate the effectiveness of educational methods on CLABSI rates in adult ICUs. A systematic literature search was conducted using the electronic databases of Medline, Cumulative Index to Nursing and Allied Health Literature (CINAHL) Plus, and Cochrane Database of Systematic Reviews for studies published from the beginning of 1995 to March 2020. The terms used for the search were as follows: central venous catheters, infection, central line-associated bloodstream infections, intensive care unit, and education intervention in all possible combinations and using the word 'and' between them. Data were extracted independently and crosschecked by two authors using a standard data collection form. The quality of the studies included in the review was assessed using the Methodological Index for Non-randomized Studies (MINORS). The current systematic review included 27 interventional studies of central line insertion or maintenance or both in adult ICU settings with documentation of the CLABSI incidence expressed per 1,000 catheter days. A large deviation between the length of time and type of educational interventions was found. Statistical significance was found in all studies (except one) in terms of CLABSI reduction despite the large variation of the length or the type of the educational intervention. Continuing education on infection prevention may be necessary to maintain the post-intervention results and improve clinical outcomes.

Increase in SARS-CoV-2 infected biomedical waste among low middle-income countries: environmental sustainability and impact with health implications

Studies have shown that severe acute respiratory syndrome corona virus-2 (SARS-CoV-2) is a highly infectious disease, with global deaths rising to about 360,438 as of 28 May 2020. Different countries have used various approaches such as lockdown, social distancing, maintenance of personal hygiene, and increased establishment of testing and isolation centers to manage the pandemic. Poor biomedical waste (BMW) management, treatment, and disposal techniques, especially SARS-CoV-2 infected BMW, may threaten the environmental and public health in most developing countries and, by extension, impact the economic status of individuals and the nation at large. This may increase the potential for the transmission of air/blood body fluid-borne pathogens, increase the growth of microorganisms, risk of mutagenesis, and upsurge of more virulent strain. In contrast, uncontrolled substandard burning could increase the potential spread of nosocomial infection and environmental exposure to toxic organic compounds, heavy metals, radioactive, and genotoxic bio-aerosols which might be present in the gaseous, liquid, and solid by-products. The paucity of understanding of pathophysiology and management of the SARS-CoV-2 pandemic has also necessitated the need to put in place appropriate disposal techniques to cater for the sudden increase in the global demand for personal protective equipment (PPE) and pharmaceutical drugs to manage the pandemic and to reduce the risk of preventable infection by the waste. Therefore, there is a need for adequate sensitization, awareness, and environmental monitoring of the impacts of improper handling of SARS-CoV-2 infected BMWs. Hence, this review aimed to address the issues relating to the improper management of increased SARS-CoV-2 infected BMW in low middle-income countries (LMICs).

Profiles of multidrug-resistant organisms among patients with bacteremia in intensive care units: an international ID-IRI survey

Evaluating trends in antibiotic resistance is a requisite. The study aimed to analyze the profile of multidrug-resistant organisms (MDROs) among hospitalized patients with bacteremia in intensive care units (ICUs) in a large geographical area. This is a 1-month cross-sectional survey for blood-borne pathogens in 57 ICUs from 24 countries with different income levels: lower-middle-income (LMI), upper-middle-income (UMI), and high-income (HI) countries. Multidrug-resistant (MDR), extensively drug-resistant (XDR), or pan-drug-resistant isolates were searched. Logistic regression analysis determined resistance predictors among MDROs. Community-acquired infections were comparable to hospital-acquired infections particularly in LMI (94/202; 46.5% vs 108/202; 53.5%). Although MDR (65.1%; 502/771) and XDR (4.9%; 38/771) were common, no pan-drug-resistant isolate was recovered. In total, 32.1% of MDR were Klebsiella pneumoniae, and 55.3% of XDR were Acinetobacter baumannii. The highest MDR and XDR rates were in UMI and LMI, respectively, with no XDR revealed from HI. Predictors of MDR acquisition were male gender (OR, 12.11; 95% CI, 3.025-15.585) and the hospital-acquired origin of bacteremia (OR, 2.643; 95%CI, 1.462-3.894), and XDR acquisition was due to bacteremia in UMI (OR, 3.344; 95%CI, 1.189-5.626) and admission to medical-surgical ICUs (OR, 1.481; 95% CI, 1.076-2.037). We confirm the urgent need to expand stewardship activities to community settings especially in LMI, with more paid attention to the drugs with a higher potential for resistance. Empowering microbiology laboratories and reports to direct prescribing decisions should be prioritized. Supporting stewardship in ICUs, the mixed medical-surgical ones in particular, is warranted.

Health Care-Associated Infections in a Neurocritical Care Unit of a Developing Country

BACKGROUND

Health care-associated infections (HAIs) in intensive care units (ICUs) specialized for neurocritical care (neurocritical care units [NCCUs]) are serious yet preventable complications that contribute significantly to morbidity and mortality worldwide. However, reliable data are scarcely available from the developing world. We aimed to analyze the incidence, epidemiology, microbial etiology, and outcomes of HAIs in an NCCU of a tertiary care teaching hospital in a high-income, developing country.

METHODS

In this 3-year retrospective cohort study, all patients admitted to the NCCU at the Ibn Sina Hospital in Kuwait for ≥ 2 calendar days were included. Patient demographics, hospitalization, and details of ICU-acquired infections were evaluated. Patient-related outcomes included hospital and ICU length of stay (LOS) and in-hospital mortality.

RESULTS

Among 913 patients with a total of 4921 ICU days, 79 patients had 109 episodes of HAIs. The overall incidence rate and incidence density of HAIs were 11.9/100 patients and 22.1/1000 ICU days, respectively. Multiple episodes of infection were documented in 29% of patients. The most prevalent infections were urinary tract infections (UTIs; 40/109 [37%]), bloodstream infections (30/109 [28%]), and pneumonia (16/109 [15%]). Seventy-six percent of infections were device-associated infections. A total of 158 pathogens were isolated, of which 109 were Gram-negative bacteria. Of the 40 Gram-positive bacteria, 22 were staphylococci. Seven infections were due to Clostridium difficile. There were 15 Staphylococcus aureus isolates, 47% of which were methicillin resistant. Two episodes of UTIs were due to Candida species. There were 84 Enterobacteriaceae isolates, 24% of which were extended-spectrum β-lactamase producers. All Pseudomonas aeruginosa isolates were susceptible to aminoglycosides and carbapenems. Klebsiella species were the most common pathogen (45/158 [28%]), causing pneumonia (11/33 isolates [33%]), bloodstream infections (12/37 isolates [32%]), and UTIs (16/52 isolates [31%]). One episode of bloodstream infection was due to multidrug resistant Acinetobacter baumanii which was susceptible only to colistin. Only pneumonia was independently associated with mortality, while all HAIs that occurred were significantly associated with a prolonged ICU LOS.

CONCLUSIONS

This is the first HAI surveillance study in an NCCU in Kuwait, and our results demonstrate the burden of HAIs on the neurologically injured patient, regardless of the site of infection. The high prevalence and resistant profile of HAIs in an NCCU in a developing country relative to a developed country has important implications for patient safety and emphasizes the need to strengthen collaboration between NCCU teams and infection control teams to prevent serious complications in this setting.

Bacterial profile and their antimicrobial susceptibility patterns in patients admitted at MaddaWalabu University Goba Referral Hospital, Ethiopia: a cross sectional study

BACKGROUND

Hospital acquired infections (HAIs) are one of the global concerns in resource limited settings. The aim of the study was to determine bacteria profile and their antimicrobial susceptibility patterns among patients admitted at surgical and medical wards.

METHODS

A hospital based cross-sectional study was conducted from November 2016 to July 2017 in MaddaWalabu University Goba Referral Hospital. Urine and wound swabs were processed and standard disk diffusion test was done to assess susceptibility pattern. Association among variables was determined by Chi-square test.

RESULTS

Among 207 patients enrolled, 24.6% developed HAI, of which, 62.7% and 37.3% were from surgical and medical wards, respectively. The male to female ratio was 1.5:1. The age ranged from 19 to 74 years with a mean of 41.65(±16.48) years. A total 62 bacteria were isolated in which majority of the isolates were gram negative bacteria. Most isolates were resistance to most of the antibiotics tested but sensitive to Ceftriaxone, Norfloxacin and Ciprofloxacin.

CONCLUSION

Due to the presence of high level drug resistant bacteria, empirical treatment to HAI may not be effective. Therefore, treatment should be based on the result of culture and sensitivity.

Critical care nurses' compliance and barriers toward ventilator-associated pneumonia prevention guidelines: cross-sectional survey

OBJECTIVES

This study aims to determine the compliance of critical care nurses with the ventilator-associated pneumonia prevention guidelines and the factors that affect their compliance. We also explored the barriers faced by the nurses in the implementation of these guidelines.

METHODS

A cross-sectional descriptive survey was conducted using a self-administered questionnaire containing 17 recommended strategies to prevent ventilator-associated pneumonia and 15 possible barriers. All critical care nurses of varying qualifications, levels of experience, and nationalities working in adult ICUs were invited. Between January and March 2018, the questionnaire was distributed to 283 nurses at eight ICUs in five public hospitals in Almadinah Almunawwarah, KSA.

RESULTS

A total of 229 invitees responded to the questionnaire. The mean compliance score was 85.9%. More than half (54%) of the sample had a high or acceptable compliance level. The lowest compliance rate was reported for the suctioning of subglottic secretions. The main reported barriers were the shortage of nursing staff, forgetfulness, and hospital cost control policies. Working in general ICUs with the capacity of 10-15 beds or prior education related to ventilator-associated pneumonia prevention influenced the nurses' compliance.

CONCLUSION

In our study, the overall compliance of the critical care nurses with the ventilator-associated pneumonia prevention guidelines is acceptable. Shortage of nursing staff, forgetfulness, and cost control policies were the main reported barriers to compliance.

Multicenter Study of Device-Associated Infection Rates, Bacterial Resistance, Length of Stay, and Mortality in Intensive Care Units of 2 Cities of Vietnam: International Nosocomial Infection Control Consortium Findings

OBJECTIVE

The aim of the study was to report the results of the International Nosocomial Infection Control Consortium (INICC) study conducted from May 2008 to March 2015.

METHODS

A device-associated healthcare-acquired infection surveillance study in three adult intensive care units (ICUs) and 1 neonatal ICU from 4 hospitals in Vietnam using U.S. the Centers for Disease Control and Prevention's National Healthcare Safety Network (CDC/NHSN) definitions and criteria as well as INICC methods.

RESULTS

We followed 1592 adult ICU patients for 12,580 bed-days and 845 neonatal ICU patients for 4907 bed-days. Central line-associated bloodstream infection (CLABSI) per 1000 central line-days rate was 9.8 in medical/surgical UCIs and 1.5 in the medical ICU. Ventilator-associated pneumonia (VAP) rate per 1000 mechanical ventilator-days was 13.4 in medical/surgical ICUs and 23.7 in the medical ICU. Catheter-associated urinary tract infection (CAUTI) rate per 1000 urinary catheter-days was 0.0 in medical/surgical ICUs and 5.3 in the medical ICU. While most device-associated healthcare-acquired infection rates were similar to INICC international rates (4.9 [CLABSI]; 16.5 [VAP]; 5.3 [CAUTI]), they were higher than CDC/NHSN rates (0.8 [CLABSI], 1.1 [VAP], and 1.3 [CAUTI]) for medical/surgical ICUs, with the exception of CAUTI rate for medical/surgical ICU and CLABSI rate for the medical ICU. Because of limited resources of our Vietnamese ICUs, cultures could not be taken as required by the CDC/NHSN criteria, and therefore, there was underreporting of CLABSI and CAUTI, influencing their rates. Most device utilization ratios and bacterial resistance percentages were higher than INICC and CDC/NHSN rates.

CONCLUSIONS

Device-associated healthcare-acquired infection rates found in the ICUs of our study were higher than CDC/NHSN US rates, but similar to INICC international rates. It is necessary to build more capacity to conduct surveillance and prevention strategies.
