Effectiveness of supervised implementation of an oral health care protocol on ventilator-associated pneumonia patients in intensive care units: a double-blind multicenter randomized controlled trial

The available scientific evidence suggests a significant association between oral bacteria and the incidence of ventilator-associated pneumonia (VAP). The aim of this study was to determine the effectiveness of an oral health protocol in the prevention of ventilator-associated pneumonia. In this multi-center RCT, conducted in the intensive care units of neurological patients in three general teaching hospitals of two provinces located in the west of the Iran, a consecutive sample of 200 intubated patients were initially recruited. Patients were randomly allocated to the intervention (received oral health care based on evidence-based oral health protocol) or control (routine oral health care) groups. Both groups received their prescribed treatment regimen for seven consecutive days. The percentage of VAP diagnoses as main outcome assessed using clinical pulmonary infection score (CPIS). The rate of VAP in the intervention and control groups was 5% and 64%, respectively. The intervention reduced the risk of VAP by 97% and this difference was statistically significant (P <0.001). The chance of VAP occurrence in patients with lower levels of consciousness in univariate and multivariate analysis was significantly higher (OR: 2.38; 95%CI: 1.11-5.26) P <0.05). The results of our study suggest that the use of a dynamic supervised oral health care guideline is more effective than the routinely used protocols in the intensive care units of hospitals.

Causative bacteria of ventilator-associated pneumonia in intensive care unit in Bahrain: Prevalence and antibiotics susceptibility pattern.

Ventilator-associated pneumonia (VAP) is defined as pneumonia that occurs two calendar days following endotracheal intubation or after that. It is the most common infection encountered among intubated patients. VAP incidence showed wide variability between countries. To define the VAP incidence in the intensive care unit (ICU) in the central government hospital in Bahrain and review the risk factors and the predominant bacterial pathogens with their antimicrobial susceptibility pattern. The research was a prospective cross-sectional observational study over six months from November 2019 to June 2020. It included adult and adolescent patients (> 14 years old) admitted to the ICU and required intubation and mechanical ventilation. VAP was diagnosed when it occurred after 48 h after endotracheal intubation using the clinical pulmonary infection score, which considers the clinical, laboratory, microbiological, and radiographic evidence. The total number of adult patients admitted to the ICU who required intubation and mechanical ventilation during the study period was 155. Forty-six patients developed VAP during their ICU stay (29.7%). The calculated VAP rate was 22.14 events per 1000 ventilator days during the study period, with a mean age of 52 years ± 20. Most VAP cases had late-onset VAP with a mean number of ICU days before the development of VAP of 9.96 ± 6.55. Gram-negative contributed to most VAP cases in our unit, with multidrug-resistant Acinetobacter being the most identified pathogen. The reported VAP rate in our ICU was relatively high compared to the international benchmark, which should trigger a vital action plan for reinforcing the implementation of the VAP prevention bundle.

Ventilator associated pneumonia in intensive care unit patients: a systematic review.

Ventilator-associated pneumonia (VAP) is the most common ICU acquired pneumonia among patients who are invasively intubated for mechanical ventilation. Patients with VAP suffer an increased mortality risk, financial burden, and length of stay in the hospital. The authors aimed to review the literature to describe the incidence, mortality, and microbiological evidence of VAP. We selected 13 peer-reviewed articles published from 1 January 2010 to 15 September 2022 from electronic databases for studies among adult or pediatric patients diagnosed with VAP expressed per thousand days admitted in the ICU. The VAP rates ranged from 7 to 43 per thousand days, varying among different countries of the world. A significant rate of mortality was observed in 13 studies ranging from 6.3 to 66.9%. Gram-negative organisms like Acinetobacter spp., Pseudomonas aeruginosa Gram-positive organisms like Staphylococcus aureus were frequently found. Our findings suggest an alarming situation of VAP among patients admitted to the intensive care units with increasing incidence and mortality. The review also found that VAP is more common in males and that there is a significant variation in the incidence and mortality rates of VAP among different countries. The findings of this review can inform the development of infection control and prevention strategies to reduce the burden of VAP. Thus, there is a crucial need for control and preventive measures like interventional studies and educational programs on staff training, hand-hygiene, and the appropriate use of ventilator bundle approach to curb this preventable threat that is increasing at an alarming rate.

Multidrug-resistant ventilator-associated pneumonia (VAP) before and during the COVID-19 pandemic among hospitalized patients in a tertiary-care private hospital

Background: Data on the incidence and outcome of ventilator-associated pneumonia (VAP) and multidrug-resistant VAP (MDR-VAP) among COVID-19 patients are limited. We compared the incidence and incidence density (ie, number of VAP per 1,000 ventilatory days) of MDR-VAP prior to and during the COVID-19 period in an urban, tertiary-care hospital. Methods: A retrospective study was conducted to compare the incidence, profile, and outcomes of patients with MDR-VAP during the pre–COVID-19 period (2018–2019) and during the COVID-19 pandemic (2020–2021). Results: In total, 80 (22%) of 362 patients developed VAP and were included in the cohort: 27 (33.75%) from the pre–COVID-19 period and 53 (66.25%) from the COVID-19 period, respectively. Most were male [20 (74%) of 27 vs 34 (64%) of 53], with median ages of 66 years (range, 35–90) and 67 years (range, 32–92) in the pre–COVID-19 and COVID-19 periods, respectively. Comorbidities were similar between the 2 periods, except for cardiovascular disease (14 vs 11; P = .005) and chronic lung disease (14 vs 9; P = .0012), which decreased significantly from the pre–COVID-19 period to the COVID-19 period. Only 15 (56%) of 27 versus 37 (70%) of 53 patients developed MDR-VAP during the pre–COVID-19 and COVID-19 period, with incidence densities of 19.3 of 1,000 and 27.8 of 1,000 ventilator days (P = .0371), respectively. The median length of stay prior to VAP for the pre–COVID-19 and COVID-19 periods were 17 and 10 days, respectively (P &lt; .0001). Extended-spectrum β-lactamase (ESBL) resistance increased significantly from 1 (3.7%) of 27 before COVID-19 to 15 (28.3%) of 53 during the COVID-19 period. Carbapenem-resistant Enterobacteriaceae (CRE) resistance was higher before COVID-19 than during the COVID-19 period: 15 (56%) of 27 versus 10 (19%) of 53. In both periods, Klebsiella pneumoniae and Acinetobacter baumannii were the most common pathogens isolated. Mortality was high in both periods at 93% and 83%, respectively. Only female sex was associated with MDR-VAP in the COVID-19 period on multivariate analysis (OR, 3.47; 95% CI, 1.019–11.824; P &lt; .047). Conclusions: The frequency of VAP and MDR-VAP increased during the COVID-19 period, despite a shorter median hospital stay. Mechanisms of resistance differed in the pre–COVID-19 and COVID-19 periods. Mortality with VAP was extremely high. The factors associated with increased risk of VAP and COVID-19 need to be studied further, and measures to prevent VAP should be prioritized.Disclosures: None

Early- vs Late-onset Ventilator-associated Pneumonia in Critically Ill Adults: Comparison of Risk Factors, Outcome, and Microbial Profile.

Ventilator-associated pneumonia (VAP) is one of the most frequent hospital-acquired infections, which develops in mechanically ventilated patients after 48 hours of mechanical ventilation. The purpose of this study was to determine the incidence rate, various risk factors, microbiological profile, and outcome of early- vs late-onset ventilator-associated pneumonia (VAP) in medical intensive care unit (MICU). This prospective study was conducted on 273 patients admitted to the MICU in JIPMER, Puducherry, from October 2018 to September 2019. The incidence of VAP was 39.59 per 1000 ventilation days of MICU patients (93/273). Of these, 53 (56.9%) patients had early-onset VAP and 40 (43.1%) had late-onset VAP. Multiple logistic regression analysis showed that steroid therapy, supine head position, coma or impaired unconsciousness, tracheostomy, and re-intubation were found to be independent predictors of early- and late-onset VAP, respectively. Most cases of VAP were caused by Gram-negative bacteria (90.6%), with nonfermenters contributing to 61.8%. The most frequent pathogens causing early-onset VAP were Acinetobacter baumannii (28.9%) and Pseudomonas aeruginosa (20.6%), while in late-onset VAP, A. baumannii (32.9%) and Klebsiella pneumoniae (21.9%) were the most common. Maximum death rate was seen in patients infected with Escherichia coli (50%) and Stenotrophomonas maltophilia (38.5%). There was no significant association between the presence of VAP and mortality among the studied population. The incidence of VAP in our study was high. There were no significant differences in the prevalence of pathogens associated with early-onset or late-onset VAP. Our study shows that early-onset and late-onset VAP have different risk factors, highlighting the need for developing different preventive and therapeutic strategies.

Ventilator-associated pneumonia in neurocritically ill patients: insights from the ENIO international prospective observational study

BackgroundAcute brain injured (ABI) patients are at high risk of developing ventilator-associated pneumonia (VAP). However, incidence, risk factors and effects on outcome of VAP are not completely elucidated in this population. The primary aim of this study was to determine the incidence of VAP in a cohort of ABI patients. The secondary objectives included the identification of risk factors for development of VAP, and the impact of VAP on clinical outcomes. Clinical outcomes were defined as intensive care unit length of stay (ICU-LOS), duration of invasive mechanical ventilation (IMV), and ICU mortality.MethodsPre-planned sub-analysis of the Extubation strategies in Neuro-Intensive care unit (ICU) patients and associations with Outcomes (ENIO) international multi-center prospective observational study. Patients with available data on VAP, who received at least 48 h of IMV and ICU-LOS ≥ 72 h were included.ResultsOut of 1512 patients included in the ENIO study, 1285 were eligible for this analysis. The prevalence of VAP was 39.5% (33.7 cases /1000 ventilator-days), with a high heterogeneity across countries and according to the type of brain injury. VAP was significantly more frequent in male patients, in those with smoke habits and when intraparenchymal probe (IP), external ventricular drain (EVD) or hypothermia (p < 0.001) were used. Independent risk factors for VAP occurrence were male gender, the use of IP, hypothermia, and the occurrence of tracheobronchitis during ICU stay. VAP was not an independent risk factor for ICU mortality (Hazard Ratio, HR = 0.71 95%CI 0.43–1.16, p = 0.168), but was independently associated with longer ICU stay (OR = 2.55 95%CI 2.01–3.23, p < 0.001).ConclusionsVAP is common in ABI patients. Male gender, IP and EVD insertion, tracheobronchitis, and the use of therapeutic hypothermia were significantly associated with VAP occurrence. VAP did not affect mortality but increased ICU-LOS.

Effects of the Selective Decontamination of the Digestive Tract (SDD) on Pulmonary Secondary Infections in Patients with COVID-19 Acute Respiratory Distress Syndrome: A Retrospective Single Centre Experience

Definitive data on the incidence rate of ventilator-associated pneumonia (VAP) in COVID-19 are still lacking, ranging from 29 to 58%. To date, most of the existing literature refers to patients who are not subjected to VAP prevention with selective decontamination of the digestive tract (SDD). We retrospectively collected data on all COVID-19 patients admitted to our ICU during the second phase of the pandemic with the aim of assessing the occurrence of VAP and the related mortality at 30 days and comparing our findings with the available literature. Of 213 patients, only 74 were eligible for the analysis. An incidence of 6.90 VAP per 1000 days of mechanical ventilation was detected. Apart from a smoking habit (0% vs. 10%, p &lt; 0.005) and diabetes (14% vs. 54%, p = 0.026), patients who developed VAP did not differ significantly from those who did not regarding comorbidities, steroid use, and the severity of COVID-19. VAP were predominantly caused by mono-microbial Gram-negative or fungal infections. Mortality was significantly higher in those who developed VAP (86 vs. 33%, p = 0.002). Our evidence aligned with the available literature in assuming a possible role of SDD in reducing the incidence of VAP in COVID-19 patients, with a possible impact on related mortality and costs.

Regularity of ventilator-associated pneumonia induced by three common pathogens

To investigate the incidence and infection regularity of ventilator-associated pneumonia (VAP) in patients undergoing tracheal intubation and to provide reference for the prevention and treatment of VAP infection in the future. A retrospective study was conducted to collect the microbial data of airway secretion cultures from 72 patients with endotracheal intubation admitted to the emergency ward of Shanghai Fifth People's Hospital from May 2020 to February 2021, and the species of microorganisms and intubation time were statistically analyzed. Among 72 patients with endotracheal intubation, males were more than females (58.33% vs. 41.67%); Patients over 60 years old accounted for 90.28%; pneumonia was the main primary disease, accounting for 58.33%. Pathogenic tests showed that: (1) 72 patients were infected with Acinetobacter baumannii (AB), Klebsiella pneumoniae (KP), and Pseudomonas aeruginosa (PA) 48 hours after intubation, 51.39% (37/72), 27.78% (20/72), and 26.39% (19/72), respectively. The infection rate of AB was significantly higher than that of KP and PA. Within 48 hours of intubation, the infection rates of AB, KP, and PA were 20.83% (15/72), 13.89% (10/72), and 4.17% (3/72), respectively. Of the 42 patients with primary pneumonia, 61.90% (26/42) were infected with one or more of the three pathogenic bacteria AB, KP, and PA 48 hours after intubation, indicating a change in the etiology of the pathogenic bacteria, with the main pathogenic bacteria transitioning from other pathogenic bacteria to AB, KP, and PA. (2) AB, KP, and PA were prone to cause late onset VAP (i.e., intubation ≥ 5 days). Respectively, among VAP patients infected with AB, late onset VAP accounted for 59.46% (22/37). Among patients infected with KP, 75.00% (15/20) had late onset VAP. Among patients infected with PA, late onset VAP accounted for 94.74% (18/19), indicating a higher proportion of late onset VAP caused by PA and KP. (3) Infection was closely related to intubation time, and the pipeline can be replaced according to the peak period of infection. AB and KP infections peaked within 4 days after intubation, reaching 57.69% (30/52) and 50.00% (15/30), respectively. It is recommended to replace the tubes or undergo sensitive antimicrobial therapy around 3-4 days after starting the machine. The proportion of PA infection after 7 days of intubation was 72.73% (16/22), and it was considered to replace the pipeline after 7 days. (4) Most of the three pathogenic bacteria, AB, KP, and PA were carbapenem resistant pathogens with multiple drug resistance. Except for PA, the infection rate of carbapenem resistant bacteria (CRAB, CRKP) was significantly higher than that of non-carbapenem resistant bacteria (AB, KP), accounting for 86.54% (45/52) and 66.67% (20/30) of the corresponding infection cases, respectively, while CRPA only accounts for 18.18% (4/22). The main differences in VAP infection caused by AB, KP, and PA pathogens are infection time, infection probability, and carbapenem resistance. Targeted prevention and treatment measures can be implemented for patients with intubation.

Short-term exposure to ambient fine particulate pollution aggravates ventilator-associated pneumonia in pediatric intensive care patients undergoing cardiovascular surgeries

BackgroundAmbient air pollutants can be hazardous to human health, especially for vulnerable children. The impact of ambient air pollutant exposure before and during intensive care unit (ICU) stays on the development of ventilator-associated pneumonia (VAP) in critically ill children has not been established. We aimed to determine the correlations between short-term exposures to ambient fine particulate matter (PM2.5) and VAP in pediatric cardiac surgery patients in the ICU, and explore the effect of delayed exposure.MethodsThe medical record of 1755 child patients requiring artificial ventilation in the ICU between December 2013 to December 2020, were analyzed. The daily average concentrations of particulate matters (PM2.5 and PM10), sulfur dioxide (SO2), and ozone (O3) were calculated from public data. Interactions between these pollutants and VAP were simulated with the distributed lag non-linear model.ResultsThree hundred forty-eight cases (19.829%) of VAP were identified in this study, while the average concentrations of PM2.5, PM10, O3 and SO2 were 58, 118, 98 and 26 μg/m3, respectively. Exposure to increased levels of PM2.5 two days prior (lag 2-day) to VAP diagnosis is significantly correlated with an enhanced risk for VAP development. Even a slight increase of 10 μg/m3 in PM2.5 can translate to a 5.4% increase in VAP incidence (95% CI: 1.4%-9.5%) while the VAP incidence increased to 11.1% (95%CI: 4.5–19.5%) when PM2.5 concentration is well below the National Ambient Air Quality standard (NAAQS) of 50 μg/m3. The association was more pronounced in those aged below 3-months, with low body mass index or suffered from pulmonary arterial hypertension.ConclusionShort-term PM2.5 exposure is a significant risk for development of VAP in pediatric patients. This risk is present even with PM2.5 levels below the NAAQS. Ambient PM2.5 may represent a previously unrecognized risk factor for pneumonia and the current environmental pollution standards need to be reevaluated to consider susceptible populations.Trial registrationThe trial was registered with the National Clinical Trial Center: The correlation between ambient air pollution and the complications in ICU underwent cardiac surgery.

Risk factors for developing ventilator-associated lower respiratory tract infection in patients with severe COVID-19: a multinational, multicentre study, prospective, observational study

Around one-third of patients diagnosed with COVID-19 develop a severe illness that requires admission to the Intensive Care Unit (ICU). In clinical practice, clinicians have learned that patients admitted to the ICU due to severe COVID-19 frequently develop ventilator-associated lower respiratory tract infections (VA-LRTI). This study aims to describe the clinical characteristics, the factors associated with VA-LRTI, and its impact on clinical outcomes in patients with severe COVID-19. This was a multicentre, observational cohort study conducted in ten countries in Latin America and Europe. We included patients with confirmed rtPCR for SARS-CoV-2 requiring ICU admission and endotracheal intubation. Only patients with a microbiological and clinical diagnosis of VA-LRTI were included. Multivariate Logistic regression analyses and Random Forest were conducted to determine the risk factors for VA-LRTI and its clinical impact in patients with severe COVID-19. In our study cohort of 3287 patients, VA-LRTI was diagnosed in 28.8% [948/3287]. The cumulative incidence of ventilator-associated pneumonia (VAP) was 18.6% [610/3287], followed by ventilator-associated tracheobronchitis (VAT) 10.3% [338/3287]. A total of 1252 bacteria species were isolated. The most frequently isolated pathogens were Pseudomonas aeruginosa (21.2% [266/1252]), followed by Klebsiella pneumoniae (19.1% [239/1252]) and Staphylococcus aureus (15.5% [194/1,252]). The factors independently associated with the development of VA-LRTI were prolonged stay under invasive mechanical ventilation, AKI during ICU stay, and the number of comorbidities. Regarding the clinical impact of VA-LRTI, patients with VAP had an increased risk of hospital mortality (OR [95% CI] of 1.81 [1.40–2.34]), while VAT was not associated with increased hospital mortality (OR [95% CI] of 1.34 [0.98–1.83]). VA-LRTI, often with difficult-to-treat bacteria, is frequent in patients admitted to the ICU due to severe COVID-19 and is associated with worse clinical outcomes, including higher mortality. Identifying risk factors for VA-LRTI might allow the early patient diagnosis to improve clinical outcomes.Trial registration: This is a prospective observational study; therefore, no health care interventions were applied to participants, and trial registration is not applicable.

Profil Bakteri Patogen dan Kepekaannya pada Pasien Ventilator Associated Pneumonia dengan Infeksi COVID- 19 di Rumah Sakit UKRIDA¬

The use of ventilators during the COVID-19 pandemic has increased the incidence of Ventilator-Associated Pneumonia (VAP). This is accompanied by a trend of antibiotic resistance resulting from irrational use. The emergence of multi-drug resistant (MDR) bacteria during the pandemic presents a challenge due to limited antibiotic options. Objective: To determined the pathogenic bacterial profile and antibiotic susceptibility in Ventilator Associated Pneumonia (VAP) patients with COVID-19 infection. Methods: This is a descriptive cross-sectional study with a retrospective approach using secondary data from the medical records of UKRIDA Hospital patients from January 2021 to August 2021. Results: Most of the study sample had characteristics of being male (71.9%), aged 25-64 years (78.1%), overweight (40.6%), and hypertension (40.6%) as the comorbid. Gram-negative bacteria is the pre-dominated bacteria in this study, with Acinetobacter baumannii, Klebsiella pneumoniae, and Stenotrophomonas maltophilia being the most isolated bacteria. Antibiotics such as colistin still showed good susceptibility to Acinetobacter baumannii and Klebsiella pneumoniae, with 75% and 90% sensitivities, respectively. Antibiotics such as linezolid, tigecycline, and gentamicin-synergy still showed (100%) sensitivity to all Gram-positive bacteria. Conclusion: The discovery of MDR bacteria in patients with VAP and the limited availability of susceptible antibiotics highlights the importance of conducting antibiotic resistance surveillance and infection control, especially in the era of COVID-19.Keywords: antibiotic susceptibility, bacteria profile, COVID-19, VAP

Association of Opioid Administration During General Anesthesia and Survival for Severely Injured Trauma Patients: A Preplanned Secondary Analysis of the PROPPR Study.

There is a lack of reported clinical outcomes after opioid use in acute trauma patients undergoing anesthesia. Data from the Pragmatic, Randomized, Optimal Platelet and Plasma Ratios (PROPPR) study were analyzed to examine opioid dose and mortality. We hypothesized that higher dose opioids during anesthesia were associated with lower mortality in severely injured patients. PROPPR examined blood component ratios in 680 bleeding trauma patients at 12 level 1 trauma centers in North America. Subjects undergoing anesthesia for an emergency procedure were identified, and opioid dose was calculated (morphine milligram equivalents [MMEs])/h. After separation of those who received no opioid (group 1), remaining subjects were divided into 4 groups of equal size with low to high opioid dose ranges. A generalized linear mixed model was used to assess impact of opioid dose on mortality (primary outcome, at 6 hours, 24 hours, and 30 days) and secondary morbidity outcomes, controlling for injury type, severity, and shock index as fixed effect factors and site as a random effect factor. Of 680 subjects, 579 had an emergent procedure requiring anesthesia, and 526 had complete anesthesia data. Patients who received any opioid had lower mortality at 6 hours (odds ratios [ORs], 0.02-0.04; [confidence intervals {CIs}, 0.003-0.1]), 24 hours (ORs, 0.01-0.03; [CIs, 0.003-0.09]), and 30 days (ORs, 0.04-0.08; [CIs, 0.01-0.18]) compared to those who received none (all P < .001) after adjusting for fixed effect factors. The lower mortality at 30 days in any opioid dose group persisted after analysis of those patients who survived >24 hours (P < .001). Adjusted analyses demonstrated an association with higher ventilator-associated pneumonia (VAP) incidence in the lowest opioid dose group compared to no opioid (P = .02), and lung complications were lower in the third opioid dose group compared to no opioid in those surviving 24 hours (P = .03). There were no other consistent associations of opioid dose with other morbidity outcomes. These results suggest that opioid administration during general anesthesia for severely injured patients is associated with improved survival, although the no-opioid group was more severely injured and hemodynamically unstable. Since this was a preplanned post hoc analysis and opioid dose not randomized, prospective studies are required. These findings from a large, multi-institutional study may be relevant to clinical practice.

Impact of early enteral nutrition on ventilator associated pneumonia in intubated severe trauma patients: A propensity score-matched study.

Early enteral nutrition (EN) is recommended for critically ill patients. However, the impact of early EN on intubated severe trauma patients remains unclear. Severely traumatized adult patients who received invasive mechanical ventilation (MV) for more than 48 h during intensive care unit (ICU) stay at our institution between 2017 and 2022 were retrospectively included. Early EN was defined as EN initiation ≤48 h from ICU admission and late EN >48 h. Propensity score matching (PSM) analysis was used to compare outcomes between the groups. The primary endpoint was the incidence of ventilator-associated pneumonia (VAP). Multivariable logistic regression analysis was performed to identify independent predictors of delayed EN. For final analysis, 337 intubated severe trauma patients were available, including 204 (60.5%) in the early EN group and 133 (39.5%) in the late EN group. After PSM, early EN patients had a lower incidence of VAP (12.9 vs. 25.8%, p = 0.026) and a shorter length of hospital stay (21 vs. 24 days, p = 0.015) compared to late EN patients. There was no demonstrable difference in mortality between the two groups. Abdominal trauma, massive blood transfusion, and serum albumin were identified as independent risk factors for delayed EN. Early EN decreased the VAP rate and reduced the length of hospital stay in invasively ventilated patients with severe trauma. Abdominal injury, massive blood transfusion and low albumin were associated with delayed EN.

Risk factors and clinical outcomes of ventilator associated pneumonia in neonates in the Neonatal Intensive Care Unit of Dr. Soetomo Hospital Surabaya

Link of Video Abstract: https://youtu.be/Si_Vw_cWchk Introduction: Ventilator-associated pneumonia (VAP) is a hospital-acquired infection in mechanical ventilation for more than two consecutive days, resulting in increased mortality and treatment costs. This study aimed to analyse the risk factors and clinical outcomes of neonatal with ventilator associated pneumonia in the neonatal intensive care unit (NICU). Methods: A case-control study was conducted on neonates who had mechanical ventilators installed for more than two consecutive days, from January 2020 to December 2021, at Dr. Soetomo Hospital, Surabaya. The risk factors studied were duration of stay in the NICU, reintubation, duration of ventilation before VAP, rate of prematurity, low birth weight, enteral feeding, and underlying disease. The clinical outcomes studied were the duration of hospital stay and the total ventilation duration. Results: The study subjects were 135 neonates consisting of 45 cases of VAP and 90 non-VAP. Significant risk factors were duration of NICU stay (p&lt;0.001), duration of ventilation before VAP (p=0.002), and rate of prematurity (p=0.024). Multivariate analysis found no independent risk factors for VAP. Hospital stay duration (p&lt;0.001) and ventilation duration were significantly correlated with the incidence of VAP (p&lt;0.001). Conclusion: Risk factors for neonatal VAP were the duration of NICU stay, duration of ventilation prior to VAP occurrence, and degree of prematurity. The impact of VAP was longer duration of hospitalisation and duration of ventilation.

Noninvasive respiratory support after extubation: a systematic review and network meta-analysis.

The effect of noninvasive respiratory support (NRS), including high-flow nasal oxygen, bi-level positive airway pressure and continuous positive airway pressure (noninvasive ventilation (NIV)), for preventing and treating post-extubation respiratory failure is still unclear. Our objective was to assess the effects of NRS on post-extubation respiratory failure, defined as re-intubation secondary to post-extubation respiratory failure (primary outcome). Secondary outcomes included the incidence of ventilator-associated pneumonia (VAP), discomfort, intensive care unit (ICU) and hospital mortality, ICU and hospital length of stay (LOS), and time to re-intubation. Subgroup analyses considered "prophylactic" versus "therapeutic" NRS application and subpopulations (high-risk, low-risk, post-surgical and hypoxaemic patients). We undertook a systematic review and network meta-analysis (Research Registry: reviewregistry1435). PubMed, Embase, CENTRAL, Scopus and Web of Science were searched (from inception until 22 June 2022). Randomised controlled trials (RCTs) investigating the use of NRS after extubation in ICU adult patients were included. 32 RCTs entered the quantitative analysis (5063 patients). Compared with conventional oxygen therapy, NRS overall reduced re-intubations and VAP (moderate certainty). NIV decreased hospital mortality (moderate certainty), and hospital and ICU LOS (low and very low certainty, respectively), and increased discomfort (moderate certainty). Prophylactic NRS did not prevent extubation failure in low-risk or hypoxaemic patients. Prophylactic NRS may reduce the rate of post-extubation respiratory failure in ICU patients.

Ventilator-associated Pneumonia in the Intensive Care Unit of the Institute of Oncology Ljubljana in 2021 and the Role of Nurses in its Prevention

BACKGROUND: Ventilator-associated pneumonia (VAP) is the most common infection in critically ill patients and has the highest mortality. It prolongs ventilation time and length of stay, increases antibiotic consumption, increases the likelihood of death, increases the cost of treatment, and is difficult to diagnose. AIM: At the intensive care unit (ICU) of the Institute of Oncology, Ljubljana, we prospectively monitor risk factors for VAP and its incidence. It is a mixed surgical/internal ICU. METHODS: A centers of disease control and prevention VAP diagnosis criteria and strategies to prevent VAP were used. Registered nurses recorded risk factors in all intubated patients in all three shifts, and the diagnosis protocol was completed by the physician in case of antibiotic administration in suspected VAP. RESULTS: The expected incidence of VAP is around 18/1,000 ventilated days. In 2021, 67 patients were mechanically ventilated in our ICU (patients who completed ventilation in that year). The total time spent on ventilation was 17,143 h or 714.3 days. As the criteria for ventilator-assisted pneumonia (VAP) is &gt;48 h of ventilation, we excluded 19 patients who had been ventilated for 48 h or less. Among 48 patients who were ventilated for &gt; 48 h, the total ventilation was 16,765 h or 698.5 days. We recorded 8 VAP in 714 days, which is 1 VAP per 89 days of ventilation or 11.2/1,000 ventilation days. Healthcare staff, especially registered nurses, play a major role in VAP prevention, providing care every day, all days of the week. Most prevention interventions and strategies are part of routine nursing care. Lack of knowledge about infection prevention and appropriate nursing care among nurses can become a barrier to adherence to evidence-based guidelines for the prevention of VAP. CONCLUSION: This study will help nurses to learn about VAP and its prevention in detail so that they can apply the knowledge in clinical practice. Understanding the pathophysiology of VAP, its risk factors and the nursing care bundle is essential for appropriate prevention and treatment of VAP. Specific protocols, strategies, and active control should be available in each ICU regarding the care bundle.

Efficacy of an Herbal Preparation (Atomy's HemoHIM®) against Ventilator-associated Pneumonia: A Randomized Controlled Clinical Trial.

Despite the standard guideline recommendations to prevent ventilator-associated pneumonia (VAP), it has remained one of the common lung infections in the intensive care unit (ICU). This clinical trial was designed to evaluate the effect of HemoHIM®, a mixture of traditional Korean medicinal plants, on preventing VAP in ICU patients. This randomized controlled clinical trial was conducted on mechanically ventilated adult ICU patients with a clinical pulmonary infection score of VAP ≤6 in the first 48 h of ventilation. Patients in the intervention group received a packet of HemoHIM daily and orally for 7 days in addition to standard prevention strategies. However, in the control group, only standard prevention strategies were carried out. All patients were followed daily for VAP incidence for 14 days. The overall VAP incidence was 36.4 and 57.4 episodes per 1000 days of mechanical ventilation in the intervention and control groups, respectively (P = 0.041; odds ratio = 0.26; 95% confidence interval = 0.070-0.944). The median length of mechanical ventilation during study follow-up was significantly lower in the intervention than in the control group (P = 0.033). The number of pneumonia-free days during the study was considerably higher in the intervention group (P value of the log-rank test = 0.023). According to the results of this study, the HemoHIM herbal supplement had beneficial effects in preventing the occurrence of VAP and significantly reduced the incidence of pneumonia in the intervention group. Further comprehensive research is required to draw more accurate conclusions.

Efficacy of Closed and Open Endotracheal Suction on Prevention of Ventilator-Associated Pneumonia on Patients Admitted to Critical Care Unit at Tertiary Care Hospital

Background: Endotracheal suctioning is a method commonly used to clean airway secretions in patients under mechanical ventilation. This study aimed to compare the effects of open and closed suction methods on the occurrence of ventilator-associated pneumonia (VAP). In the open endotracheal suction, the approach necessitates the participation of two nurses and may result in a momentary interruption of ventilation and oxygen supply due to the patient’s disconnection from the ventilation device during suctioning. In the closed endotracheal suction, the approach can be performed through connections in a closed suction set while the patient is ventilated without separating the patient from the ventilator. Objective: (1). To compare the close endotracheal suction with open endotracheal suction for the prevention of VAP. (2) To assess the incidence of VAP among intubated patients. Materials and Methods: The study was conducted among 60 patients who are on mechanical ventilator in the critical care unit in tertiary care hospital. For the study, simple random sampling technique is used for the selection of sample. Using a lottery method of sampling, one in the experimental group and one in the control group on the basis of inclusion criteria. Results: The study was done on patients who are on mechanical ventilators in the critical care unit in tertiary care hospitals. The data analysis was done using descriptive and inferential statistics. The study finding revealed that in VAP scoring of the patient’s 1st and 2nd day in open endotracheal suction, there are no significant changes in open endotracheal suction then null hypothesis was accepted (t = 0.9, P = 0.37). VAP scoring of the patient’s 2nd and 3rd day and 3rd and 1st day in open endotracheal suction, there are significant changes in open endotracheal suction method in null hypothesis was rejected (P &lt; 0.05). VAP scoring of the patient’s 1st and 2nd day and 2nd and 3rd day and 3rd and 1st day in closed endotracheal suction, there are significant changes in closed endotracheal suction then null hypothesis was rejected (P &lt; 0.05). Conclusion: The study assessed the efficacy of open endotracheal suction versus closed endotracheal suction on age, sex, duration of hospital stays, return of mechanical ventilation, and mode of ventilation are not significant but the duration of mechanical ventilation is significant. The nurses play a vital role in assessing the cardiac monitor while doing suctioning to prevent cardiorespiratory complications.

Prevention of Pneumonia due to Ventilator in Critical Patients with U Shape Oral Hygiene Model: A Systematic Review.

In critical patients, generally, microorganisms originating from nasal cause Ventilator-Associated Pneumonia (VAP). This systematic review was aimed to identify the toothbrush U shape model usage, in potentially decrease the prevalence of ventilator-associated pneumonia among patients in intensive care units. Search strategy identified 15 potentially eligible articles, were 7 RCTs, 4 Meta-analysis, and 4 Observational studies. A total of 15 studies demonstrated the use of toothbrushing and chlorhexidine in mechanically ventilator patients in preventing VAP. Ten studies found positive association between toothbrushing and the use of chlorhexidine in preventing VAP. However, there were 5 studies that did not reveal an additional decrease of VAP incidence either of CHX and only toothbrushing or combination thereof. We cautiously assumed that toothbrushing and chlorhexidine might reduce VAP but the implementation of brushing should be taken into reconsideration in the terms of maintaining it.

The effect of an infection control guideline on the incidence of ventilator-associated pneumonia in patients admitted to the intensive care units

Background and aimStandard airway care can reduce the incidence of ventilator-associated pneumonia (VAP). This study aimed to determine the effect of implementing infection control guidelines on the incidence of VAP in patients admitted to the intensive care unit (ICU).Materials and MethodsIn this clinical trial, 121 patients admitted to the intensive care units of Golestan and Imam Khomeini hospitals of Ahvaz, Iran who were under mechanical ventilation were assigned to two groups of control and intervention in non-randomly allocation. The study was conducted in two consecutive periods. In the intervention group, infection control guidelines were performed to prevent VAP and in the control group, routine care was performed. Data collection is done by used a three-part instrument. The first part included questions on the patients’ demographics and clinical information. The second part was the modified clinical pulmonary infection scale (MCPIS) for the early detection of VAP. The third part of the data collection instrument was a developed checklist through literature review. The MCPIS was completed for all patients on admission and the 5th day of the study.ResultsThe two groups were homogenous respecting their baseline characteristics (P > 0.05) including the mean MCPIS score (P > 0.05). However, the intervention group had lower body temperature (P < 0.001), lower white blood cell counts (P < 0.038), lower MCPIS score (P < 0.001), and higher PaO2/FIO2 (P < 0.013) at the end of the study. The incidence of VAP was significantly lower in the intervention group when compared to the control group (i.e. 30% vs. 65.6%, P < 0.001).ConclusionsThe implementation of infection control guidelines could significantly reduce the incidence of VAP and its diagnostic indicators in patients admitted to the ICU. Nurses are advised to use these guidelines to prevent VAP in patients admitted to ICU.
