Incidence Of Nosocomial Infections Research Articles

Morbidity-free survival in extremely premature infants after changes of clinical practices according to evidence-based guidelines: a quality improvement uncontrolled before-after study in a neonatal intensive care unit.

The evolution of our clinical practices appears to have positive effects on global and SNM-free survival and seems to have reduced the incidence of nosocomial infections. • Using global survival and severe neonatal morbidity-free survival rates allows to compare inter- and intra-team critical care practices in neonatal intensive care units. • Major changes in clinical procedures, in accordance to recent guidelines, were implemented after the restructuration of the medical team in 2018, with the expected objective of improving morbidity and mortality of extremely premature infants (EPI) in our unit. • After the changes, EPI exhibit a lower composite endpoint of "death or severe neonatal morbidity (SNM)" and were more frequently free of any SNM indicators concomitantly with a shorter median duration of invasive ventilation and parenteral nutrition. • The evolution of local clinical practices may positively impact mortality and morbidity within a few years.

Selective Digestive Decontamination: A Comprehensive Approach to Reducing Nosocomial Infections and Antimicrobial Resistance in the ICU.

Background/Objective: Multidrug-resistant (MDR) bacteria pose a significant threat to global health, especially in intensive care units (ICUs), where high antibiotic consumption drives antimicrobial resistance. Selective digestive decontamination (SDD) is a strategy designed to prevent nosocomial infections and colonization by MDR pathogens. This study aimed to evaluate the impact of implementing an SDD protocol on antibiotic consumption and colonization by carbapenemase-producing Enterobacterale (CPE) in a specific ICU setting. Methods: This quasi-experimental study was conducted in the ICU of a university hospital from June 2021 to June 2023. Patients were divided into two groups: pre-intervention (before SDD) and post-intervention (after SDD implementation). Data on antibiotic consumption (expressed as defined daily doses (DDDs) per 100 stays), nosocomial infections, colonization rates, and the incidence of MDR bacteria were collected. A statistical analysis was conducted to compare the pre- and post-intervention groups. Results: A total of 3266 patients were included, with 1532 in the pre-intervention group and 1734 in the post-intervention group. The implementation of the SDD protocol resulted in a significant reduction in total antibiotic consumption (p = 0.028), with notable decreases in carbapenem use (p < 0.01) and colonization by CPE (p = 0.0099). The incidence of nosocomial infections also decreased in the post-SDD group, although this reduction was not statistically significant. Conclusions: The implementation of the SDD protocol in this ICU setting significantly reduced antibiotic consumption and colonization by CPE. These findings suggest that SDD may be a valuable tool in managing antimicrobial resistance in critical care settings, without contributing to the development of MDR bacteria.

Clinical characteristics of SARS-CoV-2 Omicron pneumonia in immunocompromised and immunocompetent patients: A retrospective cohort study

ObjectivePrevious studies evaluating the differences in COVID-19 mortality rates between immunocompromised patients and other patient groups have shown conflicting findings. This research aimed to compare the mortality rates of immunocompromised and immunocompetent patients during the Omicron-dominant period of the SARS-CoV-2 pandemic, and to identify factors associated with prognosis. MethodsWe conducted a retrospective analysis of 1085 adult patients (aged ≥18 years) admitted with COVID-19 pneumonia to the China-Japan Friendship Hospital between December 1, 2022, and January 31, 2023. We assessed the prevalence of comorbidities, incidence of co-infections and nosocomial infections, and 30-day mortality. ResultsAmong the 1085 patients, 254 were immunocompromised, and 831 were immunocompetent. Immunocompromised patients had higher rates of non-invasive ventilation use (30.3 % vs. 21.1 %), invasive ventilation (12.2 % vs. 5.3 %), and 30-day mortality (19.7 % vs. 13.7 %) compared to immunocompetent patients. However, overall mortality rates did not significantly differ based on immunocompromised status. Cox regression analysis identified that elevated troponin T (≥0.15 ng/mL), respiratory failure, high lactate dehydrogenase (≥272.5 U/L), elevated D-dimer (≥1.295 mg/L), increased C-reactive protein (≥90 mg/L), elevated interleukin-6 (>11.67 ng/L), high peripheral blood neutrophil count (>9.84 × 10⁹/L), and immunocompromised status were independent predictors of poor COVID-19 prognosis. In the immunocompetent group, current smoking and a history of interstitial lung disease were related to a worse prognosis. ConclusionsCOVID-19 pneumonia due to the Omicron variant may lead to worse outcomes in immunocompromised patients. In immunocompetent patients, careful monitoring is essential for those with respiratory failure, smoking history, or interstitial lung disease to prevent adverse outcomes.

Beyond the distance between juridic and scientific decision-making process: An evidence-based prediction algorithm for professional liability assessment in healthcare-associated infections

BackgroundHAIs (Healthcare-Acquired-Infections) have been recently the subject of judgment n. 6386 pronounced on 3rd March 2023 by the Italian Supreme Court. This sentence provided three criteria to determine whether a health facility is responsible for the patient contracting a nosocomial infection, i.e. time criterion, topographical criterion and clinical criterion. Accordingly, the healthcare facility is obliged to prove the fulfillment of a series of preventive hygiene measures specifically detailed by the legislator. Herein, the positive predictive value of these criteria (“juridic criteria”) in the identification of professional liability for nosocomial infections was evaluated in comparison with clinical criteria reviewed by Infectious Disease specialists (“Infectious-Disease criteria”, i.e. presence of a Multidrug Resistant Organism (MDRO); development of surgical site infection; inadequate antibiotic therapy; inadequate disinfection). MethodsTwo retrospective cohorts were compared from the Portal of Telematic Services of the Ministry of Justice; 51 patients were extrapolated from Italian judgments concerning claims for Gram-negative nosocomial infections in the three-year period 2020–2022. On the other side, from the electronic database of University Hospital of Bari we extracted 349 patients affected by Gram-negative infections in the same timespan. Both “juridic” criteria and “Infectious-Disease” criteria were then applied to the full cohort after stratification for cohort of origin and after stratification for nosocomial or non-nosocomial infections. Predictive value of criteria was evaluated through receiver operating characteristic (ROC) curves and area under the curve (AUC). ResultsOverall, the incidence of definite nosocomial infections (according to final judgement or clinical records discharge letter) was 84 % in juridic cohort and 46 % in “real-world” series.Data suggested that the presence of all three juridic criteria [ROC AUC = 0.944 (95%CI = 0.924–0.963)] or the four clinical criteria [ROC AUC = 0.948 (95%CI = 0.928–0.969)] predicted well a case of nosocomial infection with professional liability.Moreover, by summarizing both criteria in a single classification system, the generated ROC curve (was the one with the highest AUC [0.9488 (95%CI = 0.928–0.969)].Accordingly, further tests were performed, evaluating the predictive value of one juridic criterium plus at one of more Infectious-Disease criteria. Interestingly, the ROCs curves demonstrated that the presence of at least 1 juridic criteria plus at least 2 Infectious Disease criteria reached a predictive value comparable to 2 or 3 juridic criteria. ConclusionsThe results highlight the efficiency of new criteria laid down in the judgment of the Italian Supreme Court to attribute liability for nosocomial infection despite the disputed distance between juridic and scientific decision-making process. In addition, the use of a combined score combining “juridic” and “Infectious-Disease” criteria provides a high-quality tool to be used by technical consultants to make up for lack of clinical documentation by passing judgments concerning litigation about professional liability in case of nosocomial infections. This sheds light on the possibility to face worldwide judicial inquiries with scientific rigor.

Study of Bacterial Contamination in the Operating Room and Newborn Intensive Care Unit: Effects of the Predominantly Used Antibiotics at Sabratha Teaching Hospital

Contamination by bacteria in the operating room (OR) and newborn intensive care units (NICU) has continued to increase the incidence of nosocomial infections and a center point of multidrug-resistant (MDR) pathogens. This study was to examine the spread of bacteria isolated from inanimate surfaces in the operating room and neonatal intensive care units at Sabratha Teaching Hospital and find out the effectiveness of the most antimicrobial used. Methods: At the Sabratha Teaching Hospital in Sabratha, Libya, a cross-sectional, descriptive study was conducted in the OR and NICU from February to May 2024. A total of 22 swab samples were collected from high-contact environmental surfaces. Isolation, identification, and antibiotic sensitivity patterns were performed via standard techniques. Results: After 48 hours of incubation, (54.5 %) of the swabbed surfaces showed positive bacterial growth and 45.5% showed no bacterial growth, of which 25% had gram-positive bacteria and 75% had gram-negative bacteria. Staphylococcus saprophyticus 3 (25%) was the identified gram-positive bacterial isolate, and Klebsiella spp. 5 (55.5%) and Pseudomonas aeruginosa 4 (44.4%) were the probable gram-negative bacterial isolates. The antimicrobial susceptibility pattern of clinical pathogens tested Staphylococcus epidermides and Klebsiella spp showed similar patterns which were sensitive to most antimicrobials used, while Pseudomonas aeruginosa was highly resistant to Cotrimoxazole, Cefatoxime, Cefixitin, Ceftazidime, Ceftricillin, and Calvu amoxicillin. Conclusion: This study confirms the need for rigorous disinfection protocols and hand hygiene to reduce the spread of these pathogens in the OR and NICU.

Evaluation of High-dose versus Standard-dose of Dexamethasone on Mortality among the Mechanically Ventilated COVID-19 Patients.

Anti-inflammatory agents like dexamethasone (DEX) are a mainstay of treatment for COVID-19. Despite randomized trials demonstrating that a 6 mg daily dose of DEX improved patient outcomes in hospitalized COVID-19 patients receiving oxygen, clinicians often prescribe higher doses of corticosteroids without evidence to support this practice. The purpose of this study was to compare outcomes of ventilated COVID-19 patients who received standard dose (SD) versus high dose (HD) DEX. This was a multi-site, retrospective, observational study on ventilated COVID-19- positive patients who received DEX for at least three days between June 1, 2020, and January 31, 2022. The primary outcome of this study was the association between mortality and SD (<6 mg daily) versus HD (>10 mg daily) DEX in ventilated COVID-19 patients. Secondary outcomes included average blood glucose (BG), number of BG readings above 200, incidence of bacterial nosocomial infection, ventilator-free days, length of stay (LOS), and ICU LOS. Of the 212 included patients, 53 (25%) received SD DEX, and 159 (75%) received HD DEX. There was no significant effect of DEX dose on mortality, number of BG readings >200, incidence of nosocomial infections, LOS, or ventilator-free days (p >0.05). After controlling for confounding factors, no difference in mortality persisted (OR 1.34 95% CI 0.62- 2.90). Average daily BG and ICU LOS were significantly greater in the HD group compared to the SD group (p = 0.003, p = 0.019, respectively). There was no association between HD DEX and mortality among ventilated COVID- 19 patients compared to SD DEX. Moreover, HD DEX is associated with detrimental effects such as prolonged ICU LOS and higher average daily BG. This study supports the use of SD DEX in ventilated COVID-19 patients.

Clinical significance of lower respiratory tract culture within 48 h of admission in patients with viral pneumonia: an observational study

BackgroundThe aim of this retrospective study was to examine the risk factors of positive lower respiratory tract cultures and to investigate whether nosocomial infections are common in patients with positive lower respiratory tract cultures.MethodsWe enrolled 86 patients diagnosed with influenza A-related critical illness who were treated at Fuzhou Pulmonary Hospital of Fujian in China between 1st October 2013 and 31st March 2019. The of admission were used to divide the enrolled patients into two groups. Sputum and bronchoalveolar lavage fluid specimens were collected within 48 h after admission for culture. All samples were cultured immediately after sampling. Nosocomial infections are defined as any symptom or sign of pulmonary infiltration, confirmed by X-ray, after 5 days of admission and positive results from one or more cultures.ResultsThe average age of this cohort was (54.13 ± 16.52) years. Based on the culture results, Staphylococcus aureus and Candida albicans had the highest positive rates (3.40% (3/86) and 20.90% (18/86), respectively). In patients with positive lower respiratory tract cultures, the incidence of nosocomial infection was 73.30% (22/30) five days after admission. However, the incidence of nosocomial infection was lower (42.80%, 24/56) in patients with negative lower respiratory tract cultures. Hemoptysis, systolic pressure at admission, and blood urea nitrogen level at admission were all independent risk factors for positive lower respiratory tract cultures within 48 h of admission.ConclusionOur data showed that a significant proportion of patients with pneumonia exhibited co-infections with bacteria or fungi within five days of hospital admission. Hemoptysis, systolic pressure, and blood urea nitrogen levels at admission emerged as the key risk factors. These findings underscore the necessity of closely monitoring patients with influenza infection, particularly for positive bacterial or fungal cultures within the initial 48 h of admission.

Prediction of Concomitant Nosocomial Infection in Patients Previously Colonized Colorectally by Multidrug-Resistant Bacteria in an SDD Setting.

Antibiotic resistance is a worldwide concern. This study retrospectively analyzed patients admitted to the ICU of a tertiary hospital over a period of 7 months who were rectally colonized by multidrug-resistant microorganisms. The incidence of concomitant nosocomial infections was estimated, thus providing the risk of a colonizing microorganism producing a nosocomial infection. Infections with the same microorganism (concomitant) or different microorganisms (non-concomitant) were analyzed in order to adjust the empirical antibiotic treatment. Patients with rectal colonization by at least one multidrug-resistant bacterium (MDRB) on admission or after ICU admission were included. All patients had complete selective digestive decontamination (SDD) prophylaxis. For univariate analysis, categorical variables are expressed as frequencies and percentages and continuous variables as means and standard deviations, or as medians and interquartile ranges. For multivariate analysis, the model is summarized with p-values and hazard ratios with 95% confidence intervals. Survival analysis was conducted using the Kaplan-Meier method, which was performed to evaluate the time elapsed from colonization to infection by the same bacteria. Statistical significance was considered at p < 0.05. Of the 130 patients with MDRB bacterial colonization analyzed, 98 remained free of infection, while 22 developed non-concomitant infections and 10 had infections concomitant to rectal colonizing bacteria. OXA-48-producing bacteria and MDR-Pseudomonas spp. incidences were 18.9% (95% CI: 7.96-35.2) and 44.4% (CI: 13.7-78.8), respectively. OXA-48-producing bacteria and MDR-Pseudomonas spp. were the only bacteria associated with the development of infections concomitant to rectal colonization in an SDD setting. The incidence of MDRB infections was low.

Risk assessment and prediction of nosocomial infections based on surveillance data using machine learning methods

BackgroundNosocomial infections with heavy disease burden are becoming a major threat to the health care system around the world. Through long-term, systematic, continuous data collection and analysis, Nosocomial infection surveillance (NIS) systems are constructed in each hospital; while these data are only used as real-time surveillance but fail to realize the prediction and early warning function. Study is to screen effective predictors from the routine NIS data, through integrating the multiple risk factors and Machine learning (ML) methods, and eventually realize the trend prediction and risk threshold of Incidence of Nosocomial infection (INI).MethodsWe selected two representative hospitals in southern and northern China, and collected NIS data from 2014 to 2021. Thirty-nine factors including hospital operation volume, nosocomial infection, antibacterial drug use and outdoor temperature data, etc. Five ML methods were used to fit the INI prediction model respectively, and to evaluate and compare their performance.ResultsCompared with other models, Random Forest showed the best performance (5-fold AUC = 0.983) in both hospitals, followed by Support Vector Machine. Among all the factors, 12 indicators were significantly different between high-risk and low-risk groups for INI (P < 0.05). After screening the effective predictors through importance analysis, prediction model of the time trend was successfully constructed (R2 = 0.473 and 0.780, BIC = -1.537 and -0.731).ConclusionsThe number of surgeries, antibiotics use density, critical disease rate and unreasonable prescription rate and other key indicators could be fitted to be the threshold predictions of INI and quantitative early warning.

Respiratory multiple infections by bacteria, viruses, fungi, and parasites in a COPD patient: A case report

SARS-CoV-2 is the causative agent of COVID-19, an infection that can manifest with mild to severe respiratory symptoms. A 70-year-old man with COVID-19 and COPD presented to a hospital complaining of breathing difficulties. A sample was taken, leading to the finding of the Acanthamoeba parasite. Stenotrophomonas maltophilia, a bacterium known for its resistance to most antibiotics and its significance as a nosocomial pathogen, was identified. Furthermore, for the first time, the Gloeotinia fungus was discovered as an endosymbiont of Acanthamoeba. The patient underwent successful treatment and was discharged from the hospital. Immunocompromised people should be concerned about the increasing incidence of nosocomial infections. The presence of Acanthamoeba should not be overlooked in respiratory disorders, as it has the potential to carry numerous pathogenic microorganisms as endosymbionts.

Safety of Early Discharge After Coronary Artery Bypass Grafting: A Nationwide Readmissions Analysis

BackgroundWe determined the safety of early discharge after coronary artery bypass grafting (CABG) in patients with uncomplicated postoperative courses and compared outcomes with routine discharge in a national cohort. We identified preoperative factors associated with readmission after early discharge after CABG. MethodsThe Nationwide Readmissions Database was queried to identify patients undergoing CABG from January 2016 to December 2018. Patients were stratified based on length of stay (LOS) as early (≤4 days) vs routine (5-10 days) discharge. Patients were excluded with hospital courses indicative of complicated stays (emergent procedures, LOS >10 days, discharge to extended care facility or with home health, index hospitalization mortality). Propensity score matching was performed to compare outcomes between cohorts. Multivariable logistic regression models were used to identify factors associated with readmission after early discharge. ResultsDuring the study period, 91,861 patients underwent CABG with an uncomplicated postoperative course (∼20% of CABG population). Of these, 31% (28,790 of 91,861) were discharged early, and 69% (63,071 of 91,861) were routinely discharged. After propensity score matching, patients discharged early had lower readmission rates at 30 days, 90 days, and up to 1 year (P < .001 for all). The index hospitalization cost was lower with early discharge ($26,676 vs $32,859; P < .001). Early discharge was associated with a lower incidence of nosocomial infection at the index hospitalization (0.17% vs 0.81%, P < .001) and readmission from infection (14.5% vs 18%, P = .016). ConclusionsEarly discharge after uncomplicated CABG can be considered in a highly selective patient population. Early-discharge patients are readmitted less frequently than matched routine-discharge patients, with a lower incidence of readmission from infection. Appropriate postdischarge processes to facilitate early discharge after CABG should be further pursued.

The Compliance of Health Workers Doing Five Moments Of Handwashing With The Incidence Of Nosocomial Infections: Literature Review

Background: Nosocomial infection is a cross-infection in nurses or patients during hospital treatment. One of the factors that can prevent nosocomial infections is health workers' compliance in carrying out 6 (six) hand washing steps. This literature review aims to determine the relationship between the compliance of health workers washing hands and the incidence of nosocomial infections in hospitals. Methods: The method used in this article is a literature review using the PRISMA Approach. Journal databases from Science Direct, PubMed, and Google Scholar in the 2019-2023 time frame. Keywords "Handwashing," "Five Moments," and "Healthcare-Associated Infections (HAIS)" from the identification results based on inclusion criteria and eligibility review obtained ten articles for review. Results: The literature review study found that adherence to five moments of hand washing significantly affected the prevention of nosocomial infections. Conclusion: It is expected that all health personnel who provide health services to patients with complete self-awareness are disciplined to carry out five moments of hand washing.

Effect of single-patient room design on the incidence of nosocomial infection in the intensive care unit: a systematic review and meta-analysis.

Previous studies have yielded varying conclusions regarding the impact of single-patient room design on nosocomial infection in the intensive care unit (ICU). We aimed to examine the impact of ICU single-patient room design on infection control. We conducted a comprehensive search of PubMed, Embase, the Cochrane Library, Web of Science, CNKI, WanFang Data, and CBM databases from inception to October 2023, without language restrictions. We included observational cohort and quasi-experimental studies assessing the effect of single- versus multi-patient rooms on infection control in the ICU. Outcomes measured included the nosocomial infection rate, incidence density of nosocomial infection, nosocomial colonization and infection rate, acquisition rate of multidrug-resistant organisms (MDROs), and nosocomial bacteremia rate. The choice of effect model was determined by heterogeneity. Our final analysis incorporated 12 studies involving 12,719 patients. Compared with multi-patient rooms in the ICU, single-patient rooms demonstrated a significant benefit in reducing the nosocomial infection rate (odds ratio [OR]: 0.68; 95% confidence interval [CI]: 0.59, 0.79; p < 0.00001). Analysis based on nosocomial infection incidence density revealed a statistically significant reduction in single-patient rooms (OR: 0.64; 95% CI: 0.44, 0.92; p = 0.02). Single-patient rooms were associated with a marked decrease in nosocomial colonization and infection rate (OR: 0.44; 95% CI: 0.32, 0.62; p < 0.00001). Furthermore, patients in single-patient rooms experienced lower nosocomial bacteremia rate (OR: 0.73; 95% CI: 0.59, 0.89; p = 0.002) and lower acquisition rate of MDROs (OR: 0.41; 95% CI: 0.23, 0.73; p = 0.002) than those in multi-patient rooms. Implementation of single-patient rooms represents an effective strategy for reducing nosocomial infections in the ICU. https://www.crd.york.ac.uk/PROSPERO/).

Incidence and mortality of community-acquired and nosocomial infections in Japan: a nationwide medical claims database study

BackgroundIt is important to determine the prevalence and prognosis of community-acquired infection (CAI) and nosocomial infection (NI) to develop treatment strategies and appropriate medical policies in aging society.MethodsPatients hospitalized between January 2010 and December 2019, for whom culture tests were performed and antibiotics were administered, were selected using a national claims-based database. The annual trends in incidence and in-hospital mortality were calculated and evaluated by dividing the patients into four age groups.ResultsOf the 73,962,409 inpatients registered in the database, 9.7% and 4.7% had CAI and NI, respectively. These incidences tended to increase across the years in both the groups. Among the patients hospitalized with infectious diseases, there was a significant increase in patients aged ≥ 85 years (CAI: + 1.04%/year and NI: + 0.94%/year, P < 0.001), while there was a significant decrease in hospitalization of patients aged ≤ 64 years (CAI: -1.63%/year and NI: -0.94%/year, P < 0.001). In-hospital mortality was significantly higher in the NI than in the CAI group (CAI: 8.3%; NI: 14.5%, adjusted mean difference 4.7%). The NI group had higher organ support, medical cost per patient, and longer duration of hospital stay. A decreasing trend in mortality was observed in both the groups (CAI: -0.53%/year and NI: -0.72%/year, P < 0.001).ConclusionThe present analysis of a large Japanese claims database showed that NI is a significant burden on hospitalized patients in aging societies, emphasizing the need to address particularly on NI.

Outcomes of patients with thrombotic thrombocytopenic purpura treated in an intensive care unit.

Background Thrombotic thrombocytopenic purpura (TTP) is a multisystem disorder characterized by widespread microthrombosis that can predispose to multiple organ failure. The literature is sparse on the outcomes of critically ill patients with TTP managed in intensive care units (ICUs). We aimed to determine the mortality of ICU patients admitted with TTP and evaluate the predictors of survival. We also compared the incidence of nosocomial infection among those who did or did not receive plasma exchange (PE). Methods We conducted a retrospective study in a tertiary ICU. Two authors screened patients for eligibility from the hospital information system based on peripheral smear reports. Adult critically ill TTP patients managed in ICU were included. Patients with a diagnosis of haemolytic uraemic syndrome, autoimmune causes of haemolysis and pregnancy-related conditions, etc. were excluded. Two authors extracted data from medical charts. No imputation of missing variables was done. Non-parametric statistics were used to report data. Statistical analyses were performed using Stata version 16. Results Of the 535 records that were screened, 33 patients were deemed eligible. Mortality among TTP patients was 14 (42%). The women to men ratio was 7:3. At admission, greater degree of anaemia, thrombocytopenia, and higher lactate dehydrogenase levels were observed in non-survivors compared to survivors (5.4 g/dl [4.8-7.1] v. 7.6 g/dl [6.1-8.9], p=0.05; 17x103 μl v. 21x103 μl, p=0.63; and 2987 (1904-3614) U/L v. 2126 U/L (1941-3319), p=0.71; respectively]. Nineteen (57%) patients had acute kidney injury (AKI), of which 11 survived: 6 recovered completely from renal failure and 5 progressed to end-stage renal disease. Nosocomial infection rates were not different among those receiving and not receiving PE therapy (7 [33%] v. 3 [25%], respectively). Conclusion TTP is more common in women and has a high mortality. Older age, low haemoglobin and higher platelet transfusions are predictors of poor survival. Nosocomial infection rates were similar irrespective of receiving PE therapy.

Epidemiological and Prognostic Assessment of Nosocomial Infections in the Surgical Emergency Resuscitation Department IBN Tofail Hospital

Nosocomial infection is an infection acquired in a healthcare establishment. It is acquired more than 48 hours after admission [1]. Intensive care units are considered a reservoir of multi-resistant bacteria due to the critical condition of patients and the practice of certain invasive care [2]. NI constitute a public health problem marked by high morbidity and mortality. The objectives of our study are:  Detail the epidemiological profile of IN  List ATB-resistant germs  Determine the main prognostic factors We carried out a prospective study from January to June 2022 including patients hospitalized during the period in the HIT RUCH department. Patients whose stay was less than 48 hours were excluded. The diagnosis of IN was suggested based on clinical and paraclinical signs and then confirmed by bacteriological analyses. The resistance profile of the germs to ATB was reported by the results of the antibiogram. Among the 92 patients who stayed more than 48 hours in intensive care, 19 presented with IN, an incidence of 20.65%, of which 89% were male and the median age was 51.7 years. The time to IN acquisition was 5.1 days. IN at the pulmonary site were predominant with a percentage of 36.84%. The germs responsible for IN were dominated by BGN including acinetobacter baumanii with 42.1% and its resistance to ATB was 100% to C3G, 65.6% to amikacin; CGP germs were represented by staphylococcus aureus with 15%. IN-related mortality was 42%. It appears in the light of our results that IN and resistance of germs to ATB are worrying. Judicious use of ATB, hand washing and use of sterile equipment are essential to reduce the incidence of nosocomial infection.

Incidence, risk factors and outcomes of nosocomial infection in adult patients supported by extracorporeal membrane oxygenation: a systematic review and meta-analysis

BackgroundAn increasing number of patients requires extracorporeal membrane oxygenation (ECMO) for life support. This supportive modality is associated with nosocomial infections (NIs). This systematic review and meta-analysis aim to assess the incidence and risk factors of NIs in adult.MethodsWe searched PubMed, Scopus, Web of Science, and ProQuest databases up to 2022. The primary endpoint was incidence of NI. Secondary endpoints included time to infection, source of infection, ECMO duration, Intensive care and hospital length of stay (LOS), ECMO survival and overall survival. Incidence of NI was reported as pooled proportions and 95% confidence intervals (CIs), while dichotomous outcomes were presented as risk ratios (RR) as the effective index and 95% CIs using a random-effects model.ResultsAmong the 4,733 adult patients who received ECMO support in the 30 included studies, 1,249 ECMO-related NIs per 1000 ECMO-days was observed. The pooled incidence of NIs across 18 studies involving 3424 patients was 26% (95% CI 14–38%).Ventilator-associated pneumonia (VAP) and bloodstream infections (BSI) were the most common NI sources. Infected patients had lower ECMO survival and overall survival rates compared to non-infected patients, with risk ratio values of 0.84 (95% CI 0.74–0.96, P = 0.01) and 0.80 (95% CI 0.71–0.90, P < 0.001), respectively.ConclusionResults showed that 16% and 20% lower of ECMO survival and overall survival in patients with NI than patients without NI, respectively. However, NI increased the risk of in-hospital mortality by 37% in infected patients compared with non-infected patients. In addition, this study identified the significant positive correlation between ECMO duration and ECMO-related NI.

Nosocomial Infections in the Neonatal Intensive Care Unit.

Nosocomial infections are relatively common in the NICU. These infections increase morbidity and mortality, particularly in the smallest and most fragile infants. The impact of these infections on long-term outcomes and health-care costs is devastating. Worldwide efforts to decrease the incidence of nosocomial infections have focused on implementing specific prevention protocols such as handwashing, central line teams, care bundles, and antimicrobial stewardship. This review summarizes common nosocomial infections in patients in the NICU.

Effectiveness of Nursing Strategies on Risk for Pneumonia Among Patients Connected to Mechanical Ventilator in Intensive Care Unit

It has been reported that the incidence of nosocomial infections in the ICU is about 2–5 times higher than in the general in-patient hospital population. The study's objective was to evaluate the effectiveness of Nursing Strategies on Risk for Pneumonia among Patients connected to Mechanical Ventilator in Intensive Care Unit. The study adopted randomized controlled trial. Forty patients were enrolled in the study after screening using CPIS scale. If the score &lt;6 the patients were included in the study and eligibility criteria were age between 25 to 60 years, duration of ventilator 48 hours and medical patients with respiratory, renal, MODS, and sepsis diagnosis. Patients subjected to surgery and connected with non-invasive ventilation were excluded from the study. Standardized questionnaire such as demographic variables, clinical variables, and Clinical Pulmonary Infection Scoring (CPIS). The data was analyzed using descriptive statistics, independent ‘t’ test, paired t test and ANOVA were used to analyze the data. Seven (35%) of them were in the age group of 51-60 years in the study group, whereas six (30%) of the patients were in the age group of 61-70 years in the control group. 12(60%) of the patients were male and eight (40%) of them were female in the study group and 10(50%) of patients were male and female respectively in the control group. Regarding mode of ventilation, 12(50%) and six (30%) of patients ventilator setting were CMV and ASV respectively, in the study group, whereas seven (35%) and six (30%) of patients ventilator settings were ASV and CMV respectively in the control group. The pretest CPIS mean score was 4.40 with a standard deviation of 0.59 and the posttest III mean value was 2.60 with a standard deviation of 0.58 and the mean difference was 1.80 between the pretest and the posttest III, which was statistically significant at p&lt;0.001 in the study group. Nursing strategies such as demand suctioning, second hourly position change, changing ventilator flow sensor every 72 hours, and oral care every fourth hour with chlorhexidine help reduce ventilator-associated pneumonia.

Clinical Profile and Outcome of Covid-19 Intensive Care Patients with Nosocomial Infections: A Single-Centred Experience from India

Background: Incidences of nosocomial infections in COVID-19 patients admitted to the intensive care unit (ICU) have become a common occurrence. Hospital-acquired infections (HAI) present increased mortality, cost-of-care, especially relevant in multidrug resistant (MDR) infections. Our study aimed to assess the clinical implications associated with HAI-infected COVID-19 patients. Patients and Methods: We conducted retrospective single-centred study on ICU-admitted adult COVID-19 patients for a year i.e., 2021-22 at a tertiary Indian institute and collated data of HAI epidemiological, clinical and microbiological reports. Results: Rate of HIA at our centre was estimated to be 10.29% and the mortality rate was 40.4%. 10 different organisms(Bacteria: 8, Fungi: 2) were detected in HAI, of which the incidence of Gram-negative infections (GNI) was highest i.e., 60% and that of Gram-positive infections (GPI)/Fungi (Fungi infected) were 20% each. Mortality was highest among GPI (36.67%), FI (13.46%), followed by and GPI (7.69%). Tocilizumab treatment decreased the risk of survivability with no significant difference in the treatment outcomes. Conclusion: This study provides a comprehensive picture of nosocomial infections characteristics among COVID-19patients and provides insights regarding the impact of treatment on the outcome of these patients with suggestions for strategies. We found that critically ill patients with COVID- 19 are at a high risk of developing HAI, especially MDR mediated CLABSI and CAUTI. Clinicians must therefore be cautious and mindful during implementing protocols for management of infectious complications with COVID-19 patients.
