Abstract Background Ventilator-Associated Pneumonia (VAP) continues to cause significant morbidity, mortality, and hospital costs, especially in the intensive care unit (ICU). This study aimed to determine incidence and factors associated with VAP in six ICUs of the University Hospital-Sahloul (Sousse, Tunisia) in 2018. Methods We conducted a prospective observational cohort study over a three months period in six ICUs of the University Hospital-Sahloul (Sousse, Tunisia) in 2018. All patients hospitalized with mechanical ventilation (MV) for more than 48 hours in the ICUs were included. Logistic regression with the stepwise method of Hosmer and Lemeshow was used to identify factors associated with VAP. Results Overall, 110 patients were enrolled. The mean age of patients was 44 ± 25 years. Of them, 66.4% were male. The median duration of MV was 5 days [2-16]. The incidence of VAP was 32% and the density incidence was 33/1000 ventilator days. The most common organism were Pseudomonas aeruginosa (n = 14). Of them, 12 were ceftazidime-resistant and thee were resistant to imipenem. Independent risk factors associated with VAP in ICU were history of antibiotic therapy during last 6 months (p = 0.007), tracheotomy (p < 0.001) and reintubation (p < 0.001). Conclusions VAP rates in our ICUs were very high. Antimicrobial stewardship programs involving pharmacists and physicians must be elaborated to optimize the antibiotic prescribing. Mechanical ventilation require more-effective interventions control in our hospital. Key messages Ventilator-Associated Pneumonia rates were very high. Independent risk factors associated with Ventilator-Associated Pneumonia were history of antibiotic therapy during last 6 months, tracheotomy and reintubation.

ABSTRACT Objectives: to analyze the diagnostic criteria for ventilator-associated pneumonia recommended by the Brazilian Health Regulatory Agency and the National Healthcare Safety Network/Centers for Disease Control and Prevention, as well as its risk factors. Methods: retrospective cohort study carried out in an intensive care unit throughout 12 months, in 2017. Analyses included chi-square, simple linear regression, and Kappa statistical tests and were conducted using Stata 12 software. Results: the sample was 543 patients who were in the intensive care unit and under mechanical ventilation, of whom 330 (60.9%) were men and 213 (39.1%) were women. Variables such as gender, age, time under mechanical ventilation, and oral hygiene proved to be significant risk factors for the development of ventilator-associated pneumonia. Conclusions: patients submitted to mechanical ventilation need to be constantly evaluated so the used diagnostic methods can be accurate and applied in an objective and standardized way in Brazilian hospitals.

Pressure injuries (PIs) are one of the most important and frequent complications in patients admitted to the intensive care unit (ICU) or those with traumatic brain injury (TBI). The purpose of this study was to determine the incidence and risk factors of PIs in patients with TBI admitted to the ICU. In this retrospective study, the medical records of 237 patients with TBI admitted to the trauma ICU of a university hospital were examined. Demographic, trauma-related, and treatment-related characteristics of all the patients were evaluated from their records. The incidence of PIs was 13.9%, while the main risk factors were a higher injury severity score, use of mechanical ventilation, vasopressor infusion, lower Braden Scale score, fever, and period of enteral feeding. This study advances the nursing practice in the ICU by predicting the development of PIs and their characteristics in patients with TBI.

It is unknown whether neonatal ventilator-associated pneumonia (VAP) caused by multidrug-resistant (MDR) pathogens and inappropriate initial antibiotic treatment is associated with poor outcomes after adjusting for confounders. Methods: We prospectively observed all neonates with a definite diagnosis of VAP from a tertiary level neonatal intensive care unit (NICU) in Taiwan between October 2017 and March 2020. All clinical features, therapeutic interventions, and outcomes were compared between the MDR–VAP and non-MDR–VAP groups. Multivariate regression analyses were used to investigate independent risk factors for treatment failure. Results: Of 720 neonates who were intubated for more than 2 days, 184 had a total of 245 VAP episodes. The incidence rate of neonatal VAP was 10.1 episodes/per 1000 ventilator days. Ninety-six cases (39.2%) were caused by MDR pathogens. Neonates with MDR–VAP were more likely to receive inadequate initial antibiotic therapy (51.0% versus 4.7%; p < 0.001) and had delayed resolution of clinical symptoms (38.5% versus 25.5%; p = 0.034), although final treatment outcomes were comparable with the non-MDR–VAP group. Inappropriate initial antibiotic treatment was not significantly associated with worse outcomes. The VAP-attributable mortality rate and overall mortality rate of this cohort were 3.7% and 12.0%, respectively. Independent risk factors for treatment failure included presence of concurrent bacteremia (OR 4.83; 95% CI 2.03–11.51; p < 0.001), septic shock (OR 3.06; 95% CI 1.07–8.72; p = 0.037), neonates on high-frequency oscillatory ventilator (OR 4.10; 95% CI 1.70–9.88; p = 0.002), and underlying neurological sequelae (OR 3.35; 95% CI 1.47–7.67; p = 0.004). Conclusions: MDR–VAP accounted for 39.2% of all neonatal VAP in the neonatal intensive care unit (NICU), but neither inappropriate initial antibiotics nor MDR pathogens were associated with treatment failure. Neonatal VAP with concurrent bacteremia, septic shock, and underlying neurological sequelae were independently associated with final worse outcomes.

Abstract Introduction Healthcare -associated infections has become a worldwide public health problem. The aim of this study was to estimate the incidence of healthcare- associated infections in a university hospital of Tunisia. Methods This was a cohort study conducted in six intensive care units in a university hospital of Tunisia during three months (from august to October 2018). Data was provided from patients’ files. Data entry and analysis was done using SPSS version 22. Multivariate analysis was used in order to identify independent risk factors for healthcare associated infection. Results A total of 202 patients were enrolled in this study. The incidence rate of healthcare-associated infections was 53,96%(109/202). The ratio infection/infected was estimated to 1.65(109/66). The incidence of multi-drug resistant pathogens was 21,28% (43/202). The most common resistant pathogens included pseudomonas aeruginosa resistant to cefdazidime in 13,76%(15/109) followed by those resistant to extended spectrum cephalosporin 11.92% (13/109), followed by carbapenem-resistant acinetobcater baumanii 6,42%(7/109) then by carbapenem resistant pathogens and enterococcus resistant to vancomycin 2.75%(3/109) and finally staphylococcus aureus resistant to methicillin 2.1%(2/1.83). The multivariate analysis showed that long duration of central line catheterisation (RR = 7.44; 95%CI[2.79-19.82]), tracheotomy(RR = 8.61;95%CI[2.09-35,39]) and length of stay (RR = 1.08; 95%CI[1.04-1.13]) were found as independent risk factors for healthcare -associated infection. Conclusions The emergence of mutli-drug resistant pathogens needs to be deeply studied and effective measures have to be taken in order to detect and prevent transmission of resistant strains and/or their resistance determinants, especially those with phenotypes having the fewest viable treatment options. Key messages The incidence of healthcare associated infection in the intensive care unit was high. Effective measures have to be taken in the intensive care unit to detect and prevent transmission of resistant pathogens.

Background Ventilator associated pneumonia is a major cause of morbidity in the intensive care unit. Difficulties in identification of the risk factors, in diagnosing and in prevention, have intensified the problem. Objectives To measure the incidence of ventilator associated pneumonia in intensive care unit and to identify the risk factors associated. Methods A prospective observational cohort study of 69 patients who were mechanically ventilated for more than 48 hours were evaluated to find out the development of nosocomial pneumonia and presence or absence of risk factors. Data were subjected to univariate analysis using chi-square and t-test. Level of significance was set at 0.05. Results Twenty two (31.88%) out of 69 patients developed ventilator associated pneumonia, majority of them between four days to 14 days. Reintubation, invasive lines, H2 blockers and low PaO2/FiO2 were identified as major risk factors in our study. Enteral feeding via nasogastric tube and use of steroids was not associated with development of ventilator associated pneumonia. The patients with ventilator associated pneumonia had significantly longer duration of mechanical ventilation (18.88±7.7 days vs 7.36±4.19 days) and stay (29±17.8 days vs 9.22±5.14 days). The morality was similar for both the groups with or without ventilator associated pneumonia. ConclusionThe incidence of ventilator pneumonia is high. Patients requiring prolonged ventilation, re-intubation, more invasive lines and H2 blockers, are at high risk and need special attention towards prevention.http://dx.doi.org/10.3126/kumj.v9i1.6258 Kathmandu Univ Med J 2011;9(1):28-31

AbstractObjective:To identify risk factors and describe the microbiology of catheter exit-site and hub colonization in neonates.Design:During a period of 2 years, we prospectively investigated 14 risk factors for catheter exit-site and hub colonization in 862 central venous catheters in a cohort of 441 neonates. Cultures of the catheter exit-site and hub were obtained using semiquantitative techniques at time of catheter removal.Setting:A neonatal intensive care unit at a university hospital.Results:Catheter exit-site colonization was found in 7.2% and hub colonization in 5.3%. Coagulase-negative staphylococci were predominant at both sites. Pathogenic flora were found more frequently at the catheter hub (36% vs 14%;P<.05). Through logistic regression, factors associated with exit-site colonization were identified as umbilical insertion (odds ratio [OR], 8.1; 95% confidence interval [CI95], 2.35-27.6;P<.001), subclavian insertion (OR, 54.6; CI95, 12.2-244;P<.001), and colonization of the catheter hub (OR, 8.9; CI95,3.5-22.8;P<.001). Catheter-hub colonization was associated with total parenteral nutrition ([TPN] OR for each day of TPN, 1.056; CI95,1.029-1.083;P<.001) and catheter exit-site colonization (OR, 6.11; CI95, 2.603-14.34;P<.001). No association was found between colonization at these sites and duration of catheterzation and venue of insertion, physician's experience, postnatal age and patient's weight, ventilation, steroids or antibiotics, and catheter repositioning.Conclusion:These data support that colonization of the catheter exit-site is associated with the site of insertion and colonization of the catheter hub with the use of TPN. There is a very strong association between colonization at both catheter sites.

Ventilator-associated pneumonia (VAP) is one of the most frequent ICU-acquired infections and a leading cause of death among patients in Intensive Care Unit (ICU). VAP is associated with prolonged duration of mechanical ventilation and ICU stay. The estimated mortality of VAP is around 10%. There are many risk factors including host related, device related and personnel related. For prevention of VAP it is recommended to minimize the exposure to mechanical ventilation and encouraging early liberation. VAP bundle as a group of evidence-based practices that, results in decrease in the incidence of VAP should be used. Patients should be reassessed daily to conrm ongoing suspicion of disease, antibiotics should be guided by cultures reports, and clinicians should consider stopping antibiotics if cultures are 1 negative.

Background The epidemiology of ventilator-associated pneumonia is well described for adults, but little information is available on risk factors for this disease in children. Objective To identify predisposing factors for ventilator-associated pneumonia in children. Methods A cross-sectional prospective cohort study of 96 patients in a 9-bed pediatric intensive care unit was performed. Variables examined were demographic characteristics, inpatient care, medications, nutrition, invasive procedures, and characteristics of mechanical ventilation. Data were analyzed by using Pearson χ2 analysis, Fisher exact and Mann-Whitney tests, odds ratios, and forward stepwise logistic regression. Results Occurrence of ventilator-associated pneumonia correlated positively with use of nasoenteral tubes (odds ratio, 5.278; P &lt; .001), intermittent administration of nutritional formula (odds ratio, 6.632; P = .005), emergency reintubation (odds ratio, 2.700; P = .02), use of vasoactive drugs (odds ratio, 5.108; P = .009), duration of mechanical ventilation (P &lt; .001), and length of stay in the pediatric intensive care unit (P &lt; .001) and in the hospital (P = .01). Conclusion Use of vasoactive drugs, presence of a nasoenteral tube, and duration of stay in the pediatric intensive care unit were independent risk factors for ventilator-associated pneumonia.
