  • Purpose: The purpose of this study was to confirm the compliance of the application of a ventilator-associated pneumonia bundle and understand its effects on the decrease in the incidence of ventilator-associated pneumonia. Methods: This was a retrospective observational study with history control group design. Subjects were selected from January to June 2014, prior to the intervention using the ventilator-associated pneumonia bundle. Subjects were also selected from October 2014 to March 2015, 3 months after the intervention. The number of subjects was 112 before the intervention, and 107 after the intervention. Results: The number of nurses who followed the bundles increased from 8 out of 29 (27.6%) before the intervention to 19 out of 29 (65.5%) after the intervention (odd ratio= 4.99, confidence interval= 1.63-15.25, p= .004). There were 3 cases of ventilator-associated pneumonia before the intervention and 1 case after the intervention. The ventilator days were 2,143 days before the intervention and 2,232 days after the intervention. The ventilator-associated pneumonia rate of the 1,000 ventilator days was 1.40 before the intervention and decreased to 0.45 after the intervention. Conclusion: This study is meaningful, as there has been little research conducted regarding the application of the ventilator-associated pneumonia bundle in South Korea.

  • Purpose: To determine whether the practice of not routinely changing ventilator circuits in patients who require prolonged mechanical ventilation is associated with ventilator-associated pneumonia (VAP). Methods: Patients were divided into two groups, ventilator circuits were routinely changed every 7 days for the control group (39) and every 14 days for the experimental group (40) over a period of 1 yr (April 1, 2009-March 31, 2010). Pediatric patients (age 17 yr or less) were not included. VAP was diagnosed by the criteria of the Centers of Disease Control and Prevention (CDC). Incidence of VAP and characteristics of infection were evaluated. Results: In the experimental group, 2 episodes of pneumonia were observed in 40 patients and 1,322 ventilator days. The rate of VAP was 1.5 per 1,000 ventilator days. There was 1 episode of pneumonia in 39 patients and 481 ventilator days for the control group. The rate of VAP was 2.1 per 1,000 ventilator days. The difference between both groups was not significant (p=.695). Conclusion: Extending ventilator circuit change interval from 7 days to 14 days does not increase the risk for VAP.

  • Purpose: This study was to analyze the factors affecting ventilator-associated pneumonia with severe trauma patients. Methods: This study conducted from May 1, 2018 to May 31, 2018 based on the medical records of the intensive care unit of a university hospital from May 1, 2017 to April 30, 2018 in Gangwon province. The inclusion criteria were 1) Trauma intensive care unit patient, 2) older than 19 years 3) without pneumonia at the time of admission. The collected data were analyzed using descriptive, correlation analysis, ANOVA, t-tests, $x^2$-tests and regression. Results: The severe trauma patients had a total of 2,877 days receiving ventilator, and nine VAP cases. The overall infection rate was 4.0%, and the VAP incidence rate was 3.13 per 1000 ventilator days. VAP in severe trauma patient affected ICU stay(OR=1.03), mechanical ventilator applied day(OR=1.04). Conclusion: Therefore, the development of an individualized VAP prevention bundle and nursing intervention for patients with trauma will be needed and further studies. In addition, there were no findings regarding the relationship between VAP occurrence and the severity of multiple traumatic injuries, so further studies of these factors should be performed.

  • Purpose: This study was conducted to identify endotracheal colonization and the incidence of ventilator-associated pneumonia related to the type of endotracheal suction system. Methods: The participants in this study were ICU patients hospitalized between October 2009 to March 2010 who used ventilators for over 48 hr with closed (CSS, n=30) or open (OSS, n=32) suction systems. To standardize the pre-intervention suction system, a suctioning protocol was taught to the ICU nurses. Collected data were analyzed using ${\chi}^2$-test, Fisher's exact test, Wilcoxon rank sums test, Wilcoxon test, Log-rank test and Poisson regression. Results: Endotracheal colonization was higher in OSS than CSS from day 1 to day 8 while using a ventilator and there was a significant difference between the two groups. The CSS reached 50% of endotracheal colonization by the 4th day, whereas for the OSS, it was the 2nd day (p=.04). The incidence of ventilator-associated pneumonia showed no significant difference. Conclusion: For patients with a high risk of pneumonia, CSS must be used to lower endotracheal colonization.

  • Purpose: This study was aimed at providing scientific evidence for minimizing ventilator-associated pneumonia(VAP) by identifying appropriate timing of exchange of circuit for mechanical ventilator that is well suitable for the medical environment of intensive care units of hospitals in Korea. Method: This was a quasi-experimental study with a convenience sample of 19 adult subjects aged over 18 years who were admitted to the NS ICU of C university hospital, and placed on mechanical ventilator. The subjects were placed in two groups, compared on the incidence rate of VAP after they received exchange of circuit either at 1-week interval (N =10) or 2-week interval (N = 9). Result: 1) When considering 1000 days as the standard unit of analysis for incidence, the incidence rate of VAP was 7.19 cases at the 1-week cycle exchange group and 15.23 at the 2-week cycle exchange group, showing no statistically significant difference between the two groups. 2) There were a total of 3 types of bacteria isolated from the patients with VAP, including 2 cases with P. aeruginosa, 1 case with Streptococcus group F and A. baumannii. Conclusion: With thorough hand washing and strict management of tracheal tube of mechanical ventilator as well as use of tracheal intubation techniques, exchange cycle of circuit of mechanical ventilator by nurses may be changed from 1-week to 2-week interval.

  • Ventilator-associated pneumonia (VAP) is a lung infection that develops in patients receiving mechanical ventilation. VAP contributes to about 50% of hospital-acquired pneumonia in ICU settings. One of the recommendation of the Institute of for Healthcare Improvement ventilator bundle is HOB elevation. HOB elevation affects shearing forces and makes higher risk for pressure injury development. Pressure injury (PI) is localized damage to the skin over a bony prominence. PI prevention guidelines recommend that HOB positioning should be lower to reduce risk for PI development which contradicts VAP prevention guidelines for the HOB between 30 and 45 degrees for ICU patients. This presents a care dilemma and tension. The purpose of this study was to perform a secondary data analysis using cumulative electronic health record data in order to determine the association of HOB elevation with VAP and PI in ICU patients. A secondary data analysis was conducted to determine whether HOB elevation is associated with VAP and PI. HOB elevation was not likely to be associated with VAP prevention whereas it was likely to be related to PI development. This is somewhat contrary to popular data and publications. Prospective cohort study is desired to inform us in an evidence-based fashion what actually is optimal HOB elevation for ventilated patients in ICU settings.

  • Purpose: Despite numerous evidence based preventive strategies of ventilator associated pneumonia (VAP) have been introduced, the incidence rate of VAP continues in an unacceptable range. The purposes of this review were to identify risk factors and diagnosis of VAP and to introduce current evidence based preventive strategies of VAP. Methods: A comprehensive literature search using keywords, including ventilator associated pneumonia were entered into a search engine. A number of highly pertinent papers relevant to the purpose of the review were identified. The papers that discussed specific preventive strategies of VAP were selected for analysis and inclusion in this review. Results: A number of evidence based preventive strategies that nurses can implement in their clinical practice to prevent VAP were identified. Such strategies include hand washing, use of protective gloves and gowns, oral care, stress ulcer prophylaxis, avoidance of unnecessary intubation, weaning protocol, sedation vacation, use of non-invasive ventilation, semi-recumbent position, continuous aspiration of subglottic secretions, and maintenance of proper endotracheal tube cuff pressure. Staff education is essential in preventing VAP. Conclusion: Preventive strategies of VAP should be applied to daily nursing care and each critical nurse should play a functional role in preventing VAP.

  • Background: Pneumonia is a frequent complication in patients undergoing mechanical ventilation, Quantitative culture of protected specimen brush(PSB) have shown satisfactory diagnostic accuracy for the diagnosis of ventilator-associated pneumonia. However PSB method is invasive, expensive, and require a bronchoscopic procedure. But endotracheal aspiration(EA) is simple and less expensive. The purpose of our study was to investigate the diagnosic value of EA quantitative cultures. Method: We studied 15 cases of ventilator-associated pneumonia(for >72h of mechanical ventilation) patients. Patients were divided into two diagnostic categories. Group I was the patients who were suspicious of clinical pneumonia, Group II was the patients for control. The obtained samples by EA and PSB were homogenized for quantitative culture with a calibrated loop method in all patients. Result: Using $10^3cfu/ml$, $10^5cfu/ml$ as threshold in quantitative culture of PSB, EA respectively, we found that EA quantitative cultures represented a relatively sentive(70%) and relatively specific (60%) method to diagnose the ventilator-associated pneumonia. Conclusion: Although EA quantitative cultures are less specific than PSB for diagnosing ventilator-associated pneumonia. EA quantitative cultures correlated with PSB quantitative culture in patients with clinical pneumonia and may be used to treat these patients when bronchoscopic procedures are not available.
