Abstract
PURPOSE To systematically review the typology, impact, quality of evidence, barriers, and facilitators to implementation of Quality Improvement (QI) interventions for adult critical care in low- and middle-income countries (LMICs). METHODS MEDLINE, EMBASE, Cochrane Library and ClinicalTrials.gov were searched on 1st September 2022. The studies were included if they described the implementation of QI interventions for adult critical care in LMICs, available as full text, in English and published after 2000. The risks of bias were assessed using the ROB 2.0/ROBINS-I tools. Intervention strategies were categorised according to a Knowledge Translation framework. Interventions' effectiveness were synthesised by vote counting and assessed with a binomial test. Barriers and facilitators to implementation were narratively synthesised using the Consolidated Framework for Implementation Research. RESULTS 78 studies were included. Risk of bias was high. The most common intervention strategies were Education, Audit & Feedback (A&F) and Protocols/Guidelines/Bundles/Checklists (PGBC). Two multifaceted strategies improved both process and outcome measures: Education and A&F (p = 0.008); and PGBC with Education and A&F (p = 0.001, p < 0.001). Facilitators to implementation were stakeholder engagement, organisational readiness for implementation, and adaptability of interventions. Barriers were lack of resources and incompatibility with clinical workflows. CONCLUSIONS The evidence for QI in critical care in LMICs is sparse and at high risk of bias but suggests that multifaceted interventions are most effective. Co-designing interventions with and engaging stakeholders, communicating relative advantages, employing local champions and adapting to feedback can improve implementation. Hybrid study designs, process evaluations and adherence to reporting guidelines would improve the evidence base.

Evaluation of a bundle approach for the prophylaxis of ventilator-associated pneumonia: A retrospective single-center Study. Glob Health Med 2023; 5:33-39. [PMID: 36865901 PMCID: PMC9974225 DOI: 10.35772/ghm.2022.01038] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/25/2022] [Revised: 08/17/2022] [Accepted: 09/12/2022] [Indexed: 11/08/2022]
Abstract
Ventilator-associated pneumonia (VAP) is defined as pneumonia occurring after the first 48 hours of intubation and mechanical ventilation and is the most frequent hospital-acquired infection associated with intensive care unit (ICU) admissions. Herein, we defined a novel VAP bundle including 10 preventive items. We analyzed compliance rates and clinical effectiveness associated with this bundle in patients undergoing intubation at our medical center. A total of 684 consecutive patients who underwent mechanical ventilation were admitted to the ICU between June 2018 and December 2020. VAP was diagnosed by at least two physicians based on the relevant United States Centers for Disease Control and Prevention criteria. We retrospectively evaluated associations between compliance and VAP incidence. The overall compliance rate was 77%, and compliance generally remained steady during the observation period. Moreover, although the number of ventilatory days remained unchanged, the incidence of VAP improved statistically significantly over time. Low compliance was identified in four categories: head-of-bed elevation of 30- 45º, avoidance of oversedation, daily assessment for extubation, and early ambulation and rehabilitation. The incidence of VAP was lower in those with an overall compliance rate of ≥ 75% than its incidence in the lower compliance group (15.8 vs. 24.1%, p = 0.018). When comparing low-compliance items between these groups, we found a statistically significant difference only for daily assessment for extubation (8.3 vs. 25.9%, p = 0.011). In conclusion, the evaluated bundle approach is effective for the prophylaxis of VAP and is thus eligible for inclusion in the Sustainable Development Goals.

Abstract
OBJECTIVES To evaluate the effect of 17-ventilator care bundles and different training strategies for critical care nurses on clinical outcomes. DESIGN A randomized controlled triple-blinded clinical trial. SETTING The multicenter study was conducted in four academic teaching hospitals in Tehran, Iran, from October 2011 to June 2015. PATIENTS A total of 1,600 adult patients (age ≥ 18 yr) who were admitted to mixed medical-surgical ICUs (> 72 hr) and received invasive ventilation (> 48 hr) were included in this study. In addition, 160 critical care nurses were recruited through letters and telephone and face-to-face invitations. INTERVENTIONS Seventeen-ventilator care bundles applied by four different groups of nurses. MEASUREMENTS AND MAIN RESULTS Clinical outcomes were compared between four groups of study which include three intervention groups (who received 17-ventilator care bundles by trained nurses) and one control group (who received routine care). According to the results, ICU length of stay, non-ICU length of stay, ventilator-associated pneumonia occurrence date, ventilator-associated pneumonia, and mortality rates were significantly higher in control group compared with other groups. CONCLUSIONS Critical care nurses training program to accurately implement 17-ventilator care bundles improves outcomes.

Abstract
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). The South East Asian Region is a part of the world with limited health resources where infectious diseases are still underestimated. We aimed to review the literature in this part of the world to describe incidence, mortality and microbiological evidence of VAP and explore preventive and control strategies. We selected 24 peer-reviewed articles published from January 1, 2000 to September 1, 2020 from electronic databases and manual searching for observational studies among adult patients diagnosed with VAP expressed per thousand days admitted in ICU. The VAP rates ranged from 2.13 to 116 per thousand days, varying among different countries of this region. A significant rate of mortality was observed in 13 studies ranging from 16.2% to 74.1%. Gram negative organisms like Acinetobacter spp., Pseudomonas aeruginosa and Klebsiella pneumoniae and Gram-positive organisms like Staphylococcus aureus and Enterococcus species were frequently found. Our findings suggest an alarming situation of VAP among patients of most of the countries of this region with increasing incidence, mortality and antibiotic resistance. Thus, there is an urgent need for cost effective control and preventive measures like interventional studies and educational programs on staff training, hand hygiene, awareness on antibiotic resistance, implementation of antibiotic stewardship programs and appropriate use of ventilator bundle approach.

Abstract
We reviewed the use of noninvasive ventilation (NIV) versus high flow nasal cannula (HFNC) oxygen in adult acute respiratory failure (ARF). We searched major databases and included randomized trials comparing at least NIV with HFNC or NIV+HFNC with NIV in ARF. Primary outcomes included intubation/re-intubation rates. Secondary outcomes were ICU mortality and morbidities. Five trials were included; three compared HFNC with NIV, one compared HFNC, NIV and oxygen whereas one compared HFNC+NIV with NIV. Patients had hypoxaemic ARF (PaO2/FiO2≤300 mmHg). Heterogeneity prevented result pooling. Three and two studies had superiority and noninferiority design, respectively. Patients were postcardiothoracic surgery, mixed medical/surgical patients and those with pneumonia. Two trials were conducted after extubation, two before intubation and one during intubation. Three trials reported intubation/re-intubation rates as the primary outcomes. The other two trials reported the lowest peripheral capillary oxygen saturation readings during bronchoscopy or intubation. In the former three trials, the odds ratio for intubation/re-intubation rates between HFNC versus the NIV group ranged from 0.80 (95% confidence interval: 0.54-1.19) to 1.65 (95% confidence interval: 0.96-2.84). In the latter two trials, only one reported a difference in the lowest peripheral capillary oxygen saturation between NIV+HFNC versus the NIV group during intubation [100% (interquartile range: 95-100) vs. 96% (interquartile range: 92-99); P=0.029]. The secondary outcomes included differences in ICU mortality and patient tolerability, favouring HFNC. Results were conflicting, but highlighted future research directions. These include patients with hypercapneic ARF, more severe hypoxaemia (PaO2/FiO2≤200 mmHg), a superiority design, an oxygen arm and patient-centred outcomes.

Abstract
Introduction: Intubation is required to maintain the airways in comatose patients and enhance oxygenation in hypoxemic or ventilation in hypercapnic subjects. Recently, the Centers of Disease Control (CDC) created new surveillance definitions designed to identify complications associated with poor outcomes. Areas covered: The new framework proposed by CDC, Ventilator-Associated Events (VAE), has a range of definitions encompassing Ventilator-Associated Conditions (VAC), Infection-related Ventilator-Associated Complications (IVAC), or Possible Ventilator-Associated Pneumonia - suggesting replacing the traditional definitions of Ventilator-Associated Tracheobronchitis (VAT) and Ventilator-Associated Pneumonia (VAP). They focused more on oxygenation variations than on Chest-X rays or inflammatory biomarkers. This article will review the spectrum of infectious (VAP & VAT) complications, as well as the main non-infectious complications, namely pulmonary edema, acute respiratory distress syndrome (ARDS) and atelectasis. Strategies to limit these complications and improve outcomes will be presented. Expert commentary: Improving outcomes should be the objective of implementing bundles of prevention, based on risk factors amenable of intervention. Promotion of measures that reduce the exposition or duration of intubation should be a priority.

Abstract
The multimodal approach for ventilator-associated pneumonia (VAP) prevention has been shown to be a successful strategy in reducing VAP rates in many intensive care units (ICU) in some countries. The simultaneous application of several measures or "bundles" to reduce VAP rates has achieved a higher impact than the progressive implementation of the individual interventions. The ultimate objective of recommendation bundles is their integration in the culture of routine healthcare of the staff in charge of ventilated patients for accomplished rates to persist over time. The noteworthy elements of this new strategy include the selection of the individual recommendations of the bundle, education of care workers (HCW) in the culture of patient safety, audit of compliance with the recommendations, commitment of the hospital management to support implementation, nomination and empowerment of local leaders of the projects in ICUs, both physicians and nurses, and the continuous collection of VAP episodes. The implementation of this new strategy is not an easy task, as both its inherent strength and important barriers to its application have become evident, which need to be overcome for maximal reduction of VAP rates.

Abstract
Ventilator-associated pneumonia (VAP) is linked to increased morbidity and mortality and clinical protocols (VAP bundles) have evolved to minimize VAP. In 2009, a quality improvement project was implemented at our institution to decrease VAP rates in adult trauma patients. AVAP prevention committee was developed, and formal evidence-based education for the nursing and physician staff was introduced. During the study period (2009–2016), 2380 patients required ICU admission to our Level II trauma center. The mean Injury Severity Score was 33 1 12, and there were 17 per cent penetrating and 83 per cent blunt injuries. The early compliance (2010) with the VAP bundle was 65 per cent. Within one year of the implementation of VAP prevention, the compliance increased to >90 per cent. Compliance has been carefully trended and has remained at 100 per cent. All of the aforementioned interventions have resulted in a sustained dramatic decline in VAP, from 12 per cent in 2009 to 0 per cent in 2016. Ongoing education and ICU policy development has become the mainstay of our trauma ICU program. The introduction of evidence-based care education imparted a culture of excellence resulting in favorable outcomes in high-risk trauma patients related to VAP prevention. Ongoing monitoring and education is required to sustain these promising outcomes.

Abstract
BACKGROUND Intensive care unit nurses are critical for managing mechanical ventilation. Continuing education is essential in building and maintaining nurses' knowledge and skills, potentially improving patient outcomes. AIMS The aim of this study was to determine whether continuing education programmes on invasive mechanical ventilation involving intensive care unit nurses are effective in improving patient outcomes. METHODS Five electronic databases were searched from 2001 to 2016 using keywords such as mechanical ventilation, nursing and education. Inclusion criteria were invasive mechanical ventilation continuing education programmes that involved nurses and measured patient outcomes. Primary outcomes were intensive care unit mortality and in-hospital mortality. Secondary outcomes included hospital and intensive care unit length of stay, length of intubation, failed weaning trials, re-intubation incidence, ventilation-associated pneumonia rate and lung-protective ventilator strategies. Studies were excluded if they excluded nurses, patients were ventilated for less than 24 h, the education content focused on protocol implementation or oral care exclusively or the outcomes were participant satisfaction. Quality was assessed by two reviewers using an education intervention critical appraisal worksheet and a risk of bias assessment tool. Data were extracted independently by two reviewers and analysed narratively due to heterogeneity. RESULTS Twelve studies met the inclusion criteria for full review: 11 pre- and post-intervention observational and 1 quasi-experimental design. Studies reported statistically significant reductions in hospital length of stay, length of intubation, ventilator-associated pneumonia rates, failed weaning trials and improvements in lung-protective ventilation compliance. Non-statistically significant results were reported for in-hospital and intensive care unit mortality, re-intubation and intensive care unit length of stay. CONCLUSION Limited evidence of the effectiveness of continuing education programmes on mechanical ventilation involving nurses in improving patient outcomes exists. Comprehensive continuing education is required. RELEVANCE TO CLINICAL PRACTICE Well-designed trials are required to confirm that comprehensive continuing education involving intensive care nurses about mechanical ventilation improves patient outcomes.

Abstract
Staphylococcus aureus (S. aureus) is a common Ventilator-Associated Pneumonia (VAP) isolate. The objective here is to define the extent and possible reasons for geographic variation in the incidences of S. aureus-associated VAP, MRSA-VAP and overall VAP. A meta-regression model of S. aureus-associated VAP incidence per 1000 Mechanical Ventilation Days (MVD) was undertaken using random effects methods among publications obtained from a search of the English language literature. This model incorporated group level factors such as admission to a trauma ICU, year of publication and use of bronchoscopic sampling towards VAP diagnosis. The search identified 133 publications from seven worldwide regions published over three decades. The summary S. aureus-associated VAP incidence was 4.5 (3.9–5.3) per 1000 MVD. The highest S. aureus-associated VAP incidence is amongst reports from the Mediterranean (mean; 95% confidence interval; 6.1; 4.1–8.5) versus that from Asian ICUs (2.1; 1.5–3.0). The incidence of S. aureus-associated VAP varies by up to three-fold (for the lowest versus highest incidence) among seven geographic regions worldwide, whereas the incidence of VAP varies by less than two-fold. Admission to a trauma unit is the most important group level correlate for S. aureus-associated VAP.

Abstract
Selective digestive decontamination (SDD, topical antibiotic regimens applied to the respiratory tract) appears effective for preventing ventilator associated pneumonia (VAP) in intensive care unit (ICU) patients. However, potential contextual effects of SDD on Staphylococcus aureus infections in the ICU remain unclear. The S. aureus ventilator associated pneumonia (S. aureus VAP), VAP overall and S. aureus bacteremia incidences within component (control and intervention) groups within 27 SDD studies were benchmarked against 115 observational groups. Component groups from 66 studies of various interventions other than SDD provided additional points of reference. In 27 SDD study control groups, the mean S. aureus VAP incidence is 9.6% (95% CI; 6.9–13.2) versus a benchmark derived from 115 observational groups being 4.8% (95% CI; 4.2–5.6). In nine SDD study control groups the mean S. aureus bacteremia incidence is 3.8% (95% CI; 2.1–5.7) versus a benchmark derived from 10 observational groups being 2.1% (95% CI; 1.1–4.1). The incidences of S. aureus VAP and S. aureus bacteremia within the control groups of SDD studies are each higher than literature derived benchmarks. Paradoxically, within the SDD intervention groups, the incidences of both S. aureus VAP and VAP overall are more similar to the benchmarks.

Abstract
BACKGROUND Ventilator-associated pneumonia (VAP) is a common nosocomial infection in pediatric intensive care units (ICUs). Ventilator-associated pneumonia protocols decrease the incidence of VAP; however, many components of these protocols are not feasible in all settings. This study was done in a large pediatric hospital in Nicaragua. OBJECTIVE The aim of this study is to implement a sustainable evidence-based VAP protocol, in a different culture, for the purpose of decreasing VAP rates. METHODS This quality improvement study used a bidirectional cohort design with the retrospective group as the control and the prospective group as the experimental population. A daily checklist monitored compliance to the implemented protocol in the prospective group. A 2-sided Fisher exact test compared the differences in VAP rates between the 2 populations. RESULTS During the 90-day implementation period, 123 ventilated patients in 3 separate ICU wings were evaluated, with 99 included in the final analysis. These data for 2014 were compared with the VAP rates recorded for the same time period in 2013. The highest adherence to the protocol was demonstrated by ICU wing 1, with a 90% decrease in VAP rates. No statistical difference in VAP rates was demonstrated by ICU 2, and ICU 3 demonstrated an increase in both patient acuity and VAP rates. DISCUSSION Implementation of a sustainable VAP protocol in a pediatric ICU in Nicaragua can reduce the incidence of VAP. Multiple barriers and challenges associated with implementation in a resource-constrained environment are discussed.

Mechanical ventilation is a life-saving invasive procedure performed in intensive care units (ICUs) where critical patients are given advanced support. The purpose of this study was to assess the effect of personnel training on the incidence of ventilator-associated pneumonia (VAP). The study, performed prospectively in the ICU, was planned in two periods. In both periods, patient characteristics were recorded on patient data forms. In the second period, ICU physicians and assistant health personnel were given regular theoretical and practical training. Twenty-two cases of VAP developed in the pre-training period, an incidence of 31.2. Nineteen cases of VAP developed in the post-training period, an incidence of 21.0 (P<0.001). Training reduced development of VAP by 31.7 %. Crude VAP mortality was 69 % in the first period and 26 % in the second (P<0.001). Statistically significant risk factors for VAP in both periods were prolonged hospitalization, increased number of days on mechanical ventilation, and enteral nutrition; risk factors determined in the first period were re-intubation, central venous catheter use and heart failure and, in the second period, erythrocyte transfusion >5 units (P<0.05). Prior to training, compliance with hand washing (before and after procedure), appropriate aseptic endotracheal aspiration and adequate oral hygiene in particular were very low. An improvement was observed after training (P<0.001). The training of personnel who will apply infection control procedures for the prevention of healthcare-associated infections is highly important. Hand hygiene and other infection control measures must be emphasized in training programmes, and standard procedures in patient interventions must be revised.

Abstract
BACKGROUND Ventilator-associated pneumonia (VAP) is a frequent hospital acquired infections among intensive care unit patients. The Institute for Healthcare Improvement has suggested a "care bundle" approach for the prevention of VAP. This report describes the effects of implementing this strategy on VAP rates. METHODS All mechanically ventilated patients admitted to the intensive care unit between 2008 and 2013 were prospectively followed for VAP development according to the National Healthcare Safety Network criteria. In 2011, a 7-element care bundle was implemented, including head-of-bed elevation 30°-45°, daily sedation vacation and assessment for extubation, peptic ulcer disease prophylaxis, deep vein thrombosis prophylaxis, oral care with chlorhexidine, endotracheal intubation with in-line suction and subglottic suctioning, and maintenance of endotracheal tube cuff pressure at 20-30 mmHg. The bundle compliance and VAP rates were then followed. RESULTS A total of 3665 patients received mechanical ventilation, and there were 9445 monitored observations for bundle compliance. The total bundle compliance before and after initiation of the VAP team was 90.7% and 94.2%, respectively (P < .001). The number of VAP episodes decreased from 144 during 2008-2010 to only 14 during 2011-2013 (P < .0001). The rate of VAP decreased from 8.6 per 1000 ventilator-days to 2.0 per 1000 ventilator-days (P < .0001) after implementation of the care bundle. CONCLUSIONS This study suggests that systematic implementation of a multidisciplinary team approach can reduce the incidence of VAP. Further sustained improvement requires persistent vigilant inspections.

Abstract
OBJECTIVE To determine the level of knowledge of the prevention of ventilator-associated pneumonia guidelines of nurses working in three intensive care units (ICU) in 3 university hospitals in a Spanish region, and evaluate the relationship between this level of knowledge and years worked in the ICU. METHOD A descriptive, prospective, cross-sectional, multicentre study was conducted using a validated and reliable questionnaire, made up by 9 questions with closed answers drawn from the EVIDENCE study. A total of 98 questionnaires were collected from ICU nurses of the three university hospitals (A, B, and C) from January to April 2014. The sample from hospital A responded the most, in contrast with the sample from hospital B, which was the one with the less participation. The Pearson correlation was calculated in order to determine the relationship between nurse years worked in ICU and level of knowledge. RESULTS Hospital A obtained in the best mean score in the questionnaire, 6.33 (SD 1.4) points, followed by hospital C with 6.21 (SD 1.4), and finally, the hospital B with 6.06 (SD 1.5) points. A p=.08 was obtained on relating years worked with the level of knowledge. CONCLUSION The results showed a high level of knowledge compared other studies. There was a tendency between the years worked in the unit and the level of knowledge in ventilator-associated pneumonia prevention.

Abstract
OBJECTIVE To assess adherence to a ventilator care bundle in an intensive care unit and to determine the impact of adherence on the rates of ventilator-associated pneumonia. METHODS A total of 198 beds were assessed for 60 days using a checklist that consisted of the following items: bed head elevation to 30 to 45º; position of the humidifier filter; lack of fluid in the ventilator circuit; oral hygiene; cuff pressure; and physical therapy. Next, an educational lecture was delivered, and 235 beds were assessed for the following 60 days. Data were also collected on the incidence of ventilator-acquired pneumonia. RESULTS Adherence to the following ventilator care bundle items increased: bed head elevation from 18.7% to 34.5%; lack of fluid in the ventilator circuit from 55.6% to 72.8%; oral hygiene from 48.5% to 77.8%; and cuff pressure from 29.8% to 51.5%. The incidence of ventilator-associated pneumonia was statistically similar before and after intervention (p=0.389). CONCLUSION The educational intervention performed in this study increased the adherence to the ventilator care bundle, but the incidence of ventilator-associated pneumonia did not decrease in the small sample that was assessed.

Abstract
BACKGROUND Ventilator-associated pneumonia (VAP) is among the most lethal of all healthcare-associated infections. Guidelines summarize interventions to prevent VAP, but translating recommendations into practice is an art unto itself. OBJECTIVE Summarize strategies to enhance adoption of VAP prevention interventions. METHODS We conducted a systematic literature review of articles in the MEDLINE database published between 2002 and 2012. We selected articles on the basis of specific inclusion criteria. We used structured forms to abstract implementation strategies and inserted them into the "engage, educate, execute, and evaluate" framework. RESULTS Twenty-seven articles met our inclusion criteria. Engagement strategies included multidisciplinary teamwork, involvement of local champions, and networking among peers. Educational strategies included training sessions and developing succinct summaries of the evidence. Execution strategies included standardization of care processes and building redundancies into routine care. Evaluation strategies included measuring performance and providing feedback to staff. CONCLUSION We summarized and organized practical implementation strategies in a framework to enhance adoption of recommended evidence-based practices. We believe this work fills an important void in most clinical practice guidelines, and broad use of these strategies may expedite VAP reduction efforts.

Abstract
BACKGROUND "Zero-VAP" is a proposal for the implementation of a simultaneous multimodal intervention in Spanish intensive care units (ICU) consisting of a bundle of ventilator-associated pneumonia (VAP) prevention measures. METHODS/DESIGN An initiative of the Spanish Societies of Intensive Care Medicine and of Intensive Care Nurses, the project is supported by the Spanish Ministry of Health, and participation is voluntary. In addition to guidelines for VAP prevention, the "Zero-VAP" Project incorporates an integral patient safety program and continuous online validation of the application of the bundle. For the latter, VAP episodes and participation indices are entered into the web-based Spanish ICU Infection Surveillance Program "ENVIN-HELICS" database, which provides continuous information about local, regional and national VAP incidence rates. Implementation of the guidelines aims at the reduction of VAP to less than 9 episodes per 1000 days of mechanical ventilation. A total of 35 preventive measures were initially selected. A task force of experts used the Grading of Recommendations, Assessment, Development and Evaluation Working Group methodology to generate a list of 7 basic "mandatory" recommendations (education and training in airway management, strict hand hygiene for airway management, cuff pressure control, oral hygiene with chlorhexidine, semi-recumbent positioning, promoting measures that safely avoid or reduce time on ventilator, and discouraging scheduled changes of ventilator circuits, humidifiers and endotracheal tubes) and 3 additional "highly recommended" measures (selective decontamination of the digestive tract, aspiration of subglottic secretions, and a short course of iv antibiotic). DISCUSSION We present the Spanish VAP prevention guidelines and describe the methodology used for the selection and implementation of the recommendations and the organizational structure of the project. Compared to conventional guideline documents, the associated safety assurance program, the online data recording and compliance control systems, as well as the existence of a pre-defined objective are the distinct features of "Zero VAP".

Abstract
OBJECTIVE We systematically reviewed ICU-based knowledge translation studies to assess the impact of knowledge translation interventions on processes and outcomes of care. DATA SOURCES We searched electronic databases (to July, 2010) without language restrictions and hand-searched reference lists of relevant studies and reviews. STUDY SELECTION Two reviewers independently identified randomized controlled trials and observational studies comparing any ICU-based knowledge translation intervention (e.g., protocols, guidelines, and audit and feedback) to management without a knowledge translation intervention. We focused on clinical topics that were addressed in greater than or equal to five studies. DATA EXTRACTION Pairs of reviewers abstracted data on the clinical topic, knowledge translation intervention(s), process of care measures, and patient outcomes. For each individual or combination of knowledge translation intervention(s) addressed in greater than or equal to three studies, we summarized each study using median risk ratio for dichotomous and standardized mean difference for continuous process measures. We used random-effects models. Anticipating a small number of randomized controlled trials, our primary meta-analyses included randomized controlled trials and observational studies. In separate sensitivity analyses, we excluded randomized controlled trials and collapsed protocols, guidelines, and bundles into one category of intervention. We conducted meta-analyses for clinical outcomes (ICU and hospital mortality, ventilator-associated pneumonia, duration of mechanical ventilation, and ICU length of stay) related to interventions that were associated with improvements in processes of care. DATA SYNTHESIS From 11,742 publications, we included 119 investigations (seven randomized controlled trials, 112 observational studies) on nine clinical topics. Interventions that included protocols with or without education improved continuous process measures (seven observational studies and one randomized controlled trial; standardized mean difference [95% CI]: 0.26 [0.1, 0.42]; p = 0.001 and four observational studies and one randomized controlled trial; 0.83 [0.37, 1.29]; p = 0.0004, respectively). Heterogeneity among studies within topics ranged from low to extreme. The exclusion of randomized controlled trials did not change our results. Single-intervention and lower-quality studies had higher standardized mean differences compared to multiple-intervention and higher-quality studies (p = 0.013 and 0.016, respectively). There were no associated improvements in clinical outcomes. CONCLUSIONS Knowledge translation interventions in the ICU that include protocols with or without education are associated with the greatest improvements in processes of critical care.

Abstract
BACKGROUND Prevention of nosocomial infection is key to providing good quality, safe healthcare. Infection control programmes (hand-hygiene campaigns and antibiotic stewardship) are effective in reducing nosocomial infections in developed countries. However, the effectiveness of these programmes in developing countries is uncertain. OBJECTIVE To evaluate the effectiveness of interventions for preventing nosocomial infections in developing countries. METHODS A systematic search for studies which evaluated interventions to prevent nosocomial infection in both adults and children in developing countries was undertaken using PubMed. Only intervention trials with a randomized controlled, quasi-experimental or sequential design were included. Where there was adequate homogeneity, a meta-analysis of specific interventions was performed using the Mantel-Haenzel fixed effects method to estimate the pooled risk difference. RESULTS Thirty-four studies were found. Most studies were from South America and Asia. Most were before-and-after intervention studies from tertiary urban hospitals. Hand-hygiene campaigns that were a major component of multifaceted interventions (18 studies) showed the strongest effectiveness for reducing nosocomial infection rates (median effect 49%, effect range 12.7-100%). Hand-hygiene campaigns alone and studies of antibiotic stewardship to improve rational antibiotic use reduced nosocomial infection rates in three studies [risk difference (RD) of -0.09 (95%CI -0.12 to -0.07) and RD of -0.02 (95% CI -0.02 to -0.01), respectively]. CONCLUSIONS Multifaceted interventions including hand-hygiene campaigns, antibiotic stewardship and other elementary infection control practices are effective in developing countries. The modest effect size of hand-hygiene campaigns alone and negligible effect size of antibiotic stewardship reflect the limited number of studies with sufficient homogeneity to conduct meta-analyses.

Abstract
BACKGROUND Healthcare-associated infections (HAIs) are a major threat to patient safety, and are associated with mortality rates varying from 5% to 35%. Important risk factors associated with HAIs are the use of invasive medical devices (e.g. central lines, urinary catheters and mechanical ventilators), and poor staff adherence to infection prevention practices during insertion and care for the devices when in place. There are specific risk profiles for each device, but in general, the breakdown of aseptic technique during insertion and care for the device, as well as the duration of device use, are important factors for the development of these serious and costly infections. OBJECTIVES To assess the effectiveness of different interventions, alone or in combination, which target healthcare professionals or healthcare organisations to improve professional adherence to infection control guidelines on device-related infection rates and measures of adherence. SEARCH METHODS We searched the following electronic databases for primary studies up to June 2012: the Cochrane Effective Paractice and Organisation of Care (EPOC) Group Specialised Register, the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, EMBASE, and CINAHL. We searched reference lists and contacted authors of included studies. We also searched the Cochrane Database of Systematic Reviews and Database of Abstracts of Reviews of Effectiveness (DARE) for related reviews. SELECTION CRITERIA We included randomised controlled trials (RCTs), non-randomised controlled trials (NRCTs), controlled before-after (CBA) studies and interrupted time series (ITS) studies that complied with the Cochrane EPOC Group methodological criteria, and that evaluated interventions to improve professional adherence to guidelines for the prevention of device-related infections. DATA COLLECTION AND ANALYSIS Two review authors independently extracted data and assessed the risk of bias of each included study using the Cochrane EPOC 'Risk of bias' tool. We contacted authors of original papers to obtain missing information. MAIN RESULTS We included 13 studies: one cluster randomised controlled trial (CRCT) and 12 ITS studies, involving 40 hospitals, 51 intensive care units (ICUs), 27 wards, and more than 3504 patients and 1406 healthcare professionals. Six of the included studies targeted adherence to guidelines to prevent central line-associated blood stream infections (CLABSIs); another six studies targeted adherence to guidelines to prevent ventilator-associated pneumonia (VAP), and one study focused on interventions to improve urinary catheter practices. We judged all included studies to be at moderate or high risk of bias.The largest median effect on rates of VAP was found at nine months follow-up with a decrease of 7.36 (-10.82 to 3.14) cases per 1000 ventilator days (five studies and 15 sites). The one included cluster randomised controlled trial (CRCT) observed, improved urinary catheter practices five weeks after the intervention (absolute difference 12.2 percentage points), however, the statistical significance of this is unknown given a unit of analysis error. It is worth noting that N = 6 interventions that did result in significantly decreased infection rates involved more than one active intervention, which in some cases, was repeatedly administered over time, and further, that one intervention involving specialised oral care personnel showed the largest step change (-22.9 cases per 1000 ventilator days (standard error (SE) 4.0), and also the largest slope change (-6.45 cases per 1000 ventilator days (SE 1.42, P = 0.002)) among the included studies. We attempted to combine the results for studies targeting the same indwelling medical device (central line catheters or mechanical ventilators) and reporting the same outcomes (CLABSI and VAP rate) in two separate meta-analyses, but due to very high statistical heterogeneity among included studies (I(2) up to 97%), we did not retain these analyses. Six of the included studies reported post-intervention adherence scores ranging from 14% to 98%. The effect on rates of infection were mixed and the effect sizes were small, with the largest median effect for the change in level (interquartile range (IQR)) for the six CLABSI studies being observed at three months follow-up was a decrease of 0.6 (-2.74 to 0.28) cases per 1000 central line days (six studies and 36 sites). This change was not sustained over longer follow-up times. AUTHORS' CONCLUSIONS The low to very low quality of the evidence of studies included in this review provides insufficient evidence to determine with certainty which interventions are most effective in changing professional behaviour and in what contexts. However, interventions that may be worth further study are educational interventions involving more than one active element and that are repeatedly administered over time, and interventions employing specialised personnel, who are focused on an aspect of care that is supported by evidence e.g. dentists/dental auxiliaries performing oral care for VAP prevention.

Abstract
OBJECTIVE Ventilator-associated pneumonia is an important cause of morbidity and mortality in critically ill patients. Evidence-based clinical practice guidelines for the prevention, diagnosis, and treatment of ventilator-associated pneumonia may improve outcomes, but optimal methods to ensure implementation of guidelines in the intensive care unit are unclear. Hence, we determined the effect of educational sessions augmented with reminders, and led by local opinion leaders, as strategies to implement evidence-based ventilator-associated pneumonia guidelines on guideline concordance and ventilator-associated pneumonia rates. DESIGN Two-year prospective, multicenter, time-series study conducted between June 2007 and December 2009. SETTING Eleven ICUs (ten in Canada, one in the United States); five academic and six community ICUs. PATIENTS At each site, 30 adult patients mechanically ventilated >48 hrs were enrolled during four data collection periods (baseline, 6, 15, and 24 months). INTERVENTION Guideline recommendations for the prevention, diagnosis, and treatment of ventilator-associated pneumonia were implemented using a multifaceted intervention (education, reminders, local opinion leaders, and implementation teams) directed toward the entire multidisciplinary ICU team. Clinician exposure to the intervention was assessed at 6, 15, and 24 months after the introduction of this intervention. MEASUREMENTS AND MAIN RESULTS The main outcome measure was aggregate concordance with the 14 ventilator-associated pneumonia guideline recommendations. One thousand three hundred twenty patients were enrolled (330 in each study period). Clinician exposure to the multifaceted intervention was high and increased during the study: 86.7%, 93.3%, 95.8%, (p < .001), as did aggregate concordance (mean [SD]): 50.7% (6.1), 54.4% (7.1), 56.2% (5.9), 58.7% (6.7) (p = .007). Over the study period, ventilator-associated pneumonia rates decreased (events/330 patients): 47 (14.2%), 34 (10.3%), 38 (11.5%), 29 (8.8%) (p = .03). CONCLUSIONS A 2-yr multifaceted intervention to enhance ventilator-associated pneumonia guideline uptake was associated with a significant increase in guideline concordance and a reduction in ventilator-associated pneumonia rates.

Abstract
INTRODUCTION This study aimed to determine the epidemiology of the three most common nosocomial infections (NI), namely, sepsis, pneumonia, and urinary tract infection (UTI), in a pediatric intensive care unit (PICU) in a developing country and to define the risk factors associated with NI. METHODS We performed a prospective study on the incidence of NI in a single PICU, between August 2009 and August 2010. Active surveillance by National Healthcare Safety Network (NHSN) was conducted in the unit and children with NI (cases) were compared with a group (matched controls) in a case-control fashion. RESULTS We analyzed 172 patients; 22.1% had NI, 71.1% of whom acquired it in the unit. The incidence densities of sepsis, pneumonia, and UTI per 1,000 patients/day were 17.9, 11.4, and 4.3, respectively. The most common agents in sepsis were Enterococcus faecalis and Escherichia coli (18% each); Staphylococcus epidermidis was isolated in 13% of cases. In pneumonias Staphylococcus aureus was the most common cause (3.2%), and in UTI the most frequent agents were yeasts (33.3%). The presence of NI was associated with a long period of hospitalization, use of invasive devices (central venous catheter, nasogastric tube), and use of antibiotics. The last two were independent factors for NI. CONCLUSIONS The incidence of NI acquired in this unit was high and was associated with extrinsic factors.

Abstract
Ventilator-associated pneumonia (VAP) is the most common infection seen in intensive care units (ICUs); it accounts for one-fourth of the infections occurring in critically ill patients and is the reason for half of antibiotic prescriptions in mechanically ventilated patients. In addition to being a financial burden on ICUs, it continues to contribute significantly to the morbidity and mortality of ICU patients, with an estimated attributable mortality rate of 8% to 15%. While the pathophysiology of VAP remains relatively unchanged, diagnostic techniques and preventive measures are constantly evolving. The focus of this article is on recent trends in VAP epidemiology, modifiable risk factors, diagnostic techniques, challenges in management, and current data on the prevention of VAP. Important messages that the reader should take away include: 1) There is no gold standard for the diagnosis of VAP; whenever VAP is suspected, if feasible, a quantitative culture should be obtained by invasive or noninvasive methods (whichever is more readily available before initiation of antibiotics); 2) Suspicion based on clinical features should prompt the initiation of a broad spectrum of antibiotics depending on suspected pathogens; 3) Close attention should be paid to de-escalation of antibiotics once microbiological results become available or as the patient starts responding clinically; the ideal duration of treatment should be 8 days instead of the conventional 10 to 14 days, except in situations where Pseudomonas may be suspected or the patient's comorbidities dictate otherwise; and 4) Prevention remains the key to reducing the burden of VAP. We promote the proven preventive measures of using noninvasive ventilation when possible, semirecumbent patient positioning, continuous aspiration of subglottic secretions, and oral chlorhexidine washes along with stress ulcer prophylaxis only after careful assessment of the risks versus benefits.

Abstract
AIMS AND OBJECTIVES The aim of this review was to critically analyse recent research that has investigated ventilator care bundle (VCB) use, with the objective of analysing its impact on ventilator-associated pneumonia (VAP) outcomes. BACKGROUND The VCB is a group of four evidence-based procedures, which when clustered together and implemented as an 'all or nothing' strategy, may result in substantial clinical outcome improvement. VAP is a nosocomial lung infection associated with endotracheal tube use in ventilated patients. Since the VCB was introduced there have been several studies that have reported significant VAP rate reductions. SEARCH STRATEGY A comprehensive search for research, published between 2004 and 2009, was conducted using Medline and PubMed. Key words were used to identify English language studies reporting VCB implementation within adult intensive care units (ICU) and associated clinical outcomes. Studies that implemented bundle variations that did not include all four elements were excluded. CONCLUSIONS Because of the limitations of the observational designs used in the studies retrieved, a definitive causal relationship between VCB use and VAP reduction cannot be stated. However, the evidence to date is strongly indicative of a positive association. Several studies reported the use of additional VCB elements. In these cases it is difficult to establish which elements are related to the measured outcomes. Further research is recommended to establish baseline outcome measures using the four-element VCB, before adding further processes singly, as well as research investigating the effect of audit and feedback on VCB compliance and its effect on clinical outcomes. RELEVANCE TO CLINICAL PRACTICE A reduction in VAP is associated with VCB use. The evidence to date, whilst not at the highest experimental level, is at the highest ethically permissible level. In the absence of contradictory research, the current evidence suggests that use of the VCB represents best practice for all eligible adult ventilated patients in ICU.

Abstract
Background: Interventional studies on the effect of alcohol-based hand rub on ventilator-associated pneumonia (VAP) among neurosurgical patients are scarce. Aim: To observe the effect of alcohol-based hand rub on tracheobronchial colonization and VAP after elective neurosurgical procedures. Materials and Methods: An interventional study using a “before–after” design in a tertiary care center in Kerala. Two 9-month study periods were compared; between these periods, an infection control protocol incorporating an alcohol-based hand rub was implemented for a period of 3 months and continued thereafter. Consecutive patients who required mechanical ventilation after neurosurgery between January and September 2006 and 2007, respectively, were included. Outcome measures included VAP rate, tracheobronchial colonization rate, profile of microorganisms and patient survival. Results: A total of 352 patients were on mechanical ventilator for a varying period of 1–125 days. The patients in the control and intervention groups were similar with regard to sex, age and type of neurosurgery. Tracheobronchial colonization was seen in 86 (48.6%) of 177 in the control group and 73 (41.7%) of 175 among the intervention group (P = 0.195). The VAP rates in the control and intervention groups were 14.03 and 6.48 per 1000 ventilator days (P = 0.08). The predominant organisms causing VAP and tracheobronchial colonization were Klebsiella and Pseudomonas aeruginosa, respectively, in both groups. Patient survival rates were 87.6% (control) and 92% (intervention). Conclusion: Clinical results indicated a better outcome, showing a reduction in tracheobronchial colonization rate and VAP rate, although this was not statistically significant.

Abstract
Infection prevention measures, specifically targeting ventilator-associated pneumonia (VAP), have been purposed as quality-of-care indicators for patients in intensive care units. The authors discuss some of the recent evidence of the prevention of nosocomial infections, with a particular emphasis on VAP. Moreover, there are several pitfalls in considering VAP rates as a safety indicator. Because of these limitations, the authors recommend the use of specific process measures, designed to reduce VAP, as the basis for interinstitutional benchmarking.

Abstract
BACKGROUND Collaborative and toolkit approaches have gained traction for improving quality in health care. OBJECTIVE To determine if a quality improvement virtual collaborative intervention would perform better than a toolkit-only approach at preventing central line-associated bloodstream infections (CLABSIs) and ventilator-associated pneumonias (VAPs). DESIGN AND SETTING Cluster randomized trial with the Intensive Care Units (ICUs) of 60 hospitals assigned to the Toolkit (n=29) or Virtual Collaborative (n=31) group from January 2006 through September 2007. MEASUREMENT CLABSI and VAP rates. Follow-up survey on improvement interventions, toolkit utilization, and strategies for implementing improvement. RESULTS A total of 83% of the Collaborative ICUs implemented all CLABSI interventions compared to 64% of those in the Toolkit group (P = 0.13), implemented daily catheter reviews more often (P = 0.04), and began this intervention sooner (P < 0.01). Eighty-six percent of the Collaborative group implemented the VAP bundle compared to 64% of the Toolkit group (P = 0.06). The CLABSI rate was 2.42 infections per 1000 catheter days at baseline and 2.73 at 18 months (P = 0.59). The VAP rate was 3.97 per 1000 ventilator days at baseline and 4.61 at 18 months (P = 0.50). Neither group improved outcomes over time; there was no differential performance between the 2 groups for either CLABSI rates (P = 0.71) or VAP rates (P = 0.80). CONCLUSION The intensive collaborative approach outpaced the simpler toolkit approach in changing processes of care, but neither approach improved outcomes. Incorporating quality improvement methods, such as ICU checklists, into routine care processes is complex, highly context-dependent, and may take longer than 18 months to achieve.

Abstract
Ventilator-associated pneumonia (VAP) remains a significant problem in the hospital setting, with very high morbidity, mortality, and cost. We performed an evidence-based review of the literature focusing on clinically relevant pharmacological and nonpharmacological interventions to prevent VAP. Owing to the importance of this condition the implementation of preventive measures is paramount in the care of mechanically ventilated patients. There is evidence that these measures decrease the incidence of VAP and improve outcomes in the intensive care unit. A multidisciplinary approach, continued education, and ventilator protocols ensure the implementation of these measures. Future research will continue to investigate cost/benefit relationships, antibiotic resistance, as well as newer technologies to prevent contamination and aspiration in mechanically ventilated patients.

Abstract
Ventilator-associated pneumonia (VAP) occurs within 24 hours of intubation and mechanical ventilation. Health care costs related to increased patient mortality, extended length of stay, and patient well-being make treatment of VAP a priority in all health care settings. The Institute for Healthcare Improvements has developed the Ventilator Bundle as a group of interventions linked to ventilator care with demonstrated outcome improvements; removal of subglottic secretions is one of these recommendations. Dental plaque and bacterial colonization of pathogens is directly related to microaspiration of bacteria into the lungs. A moist environment in the mouth maintains normal oropharyngeal bacteria, preventing overgrowth of pathogenic bacteria. Frequent oral care to include twice-a-day brushing of the teeth found a 69% reduction in respiratory tract infections.

Abstract
BACKGROUND Health-care-associated infection is the most frequent result of unsafe patient care worldwide, but few data are available from the developing world. We aimed to assess the epidemiology of endemic health-care-associated infection in developing countries. METHODS We searched electronic databases and reference lists of relevant papers for articles published 1995-2008. Studies containing full or partial data from developing countries related to infection prevalence or incidence-including overall health-care-associated infection and major infection sites, and their microbiological cause-were selected. We classified studies as low-quality or high-quality according to predefined criteria. Data were pooled for analysis. FINDINGS Of 271 selected articles, 220 were included in the final analysis. Limited data were retrieved from some regions and many countries were not represented. 118 (54%) studies were low quality. In general, infection frequencies reported in high-quality studies were greater than those from low-quality studies. Prevalence of health-care-associated infection (pooled prevalence in high-quality studies, 15·5 per 100 patients [95% CI 12·6-18·9]) was much higher than proportions reported from Europe and the USA. Pooled overall health-care-associated infection density in adult intensive-care units was 47·9 per 1000 patient-days (95% CI 36·7-59·1), at least three times as high as densities reported from the USA. Surgical-site infection was the leading infection in hospitals (pooled cumulative incidence 5·6 per 100 surgical procedures), strikingly higher than proportions recorded in developed countries. Gram-negative bacilli represented the most common nosocomial isolates. Apart from meticillin resistance, noted in 158 of 290 (54%) Staphylococcus aureus isolates (in eight studies), very few articles reported antimicrobial resistance. INTERPRETATION The burden of health-care-associated infection in developing countries is high. Our findings indicate a need to improve surveillance and infection-control practices.

Abstract
Practice guidelines are systematically developed statements and recommendations that assist the physicians and patients in making decisions about appropriate health care measures for specific clinical circumstances taking into account specific national health care structures. The 1st revision of the S-2k guideline of the German Sepsis Society in collaboration with 17 German medical scientific societies and one self-help group provides state-of-the-art information (results of controlled clinical trials and expert knowledge) on the effective and appropriate medical care (prevention, diagnosis, therapy and follow-up care) of critically ill patients with severe sepsis or septic shock. The guideline had been developed according to the “German Instrument for Methodological Guideline Appraisal” of the Association of the Scientific Medical Societies (AWMF). In view of the inevitable advancements in scientific knowledge and technical expertise, revisions, updates and amendments must be periodically initiated. The guideline recommendations may not be applied under all circumstances. It rests with the clinician to decide whether a certain recommendation should be adopted or not, taking into consideration the unique set of clinical facts presented in connection with each individual patient as well as the available resources.

Abstract
The prevention of ventilator-associated pneumonia (VAP) is a priority in the Intensive Care Unit (ICU). To achieve this goal, clinical practice guidelines recommend the simultaneous application of a heterogeneous group of preventive measures of proven effectiveness. That is why we are presently seeing a reduction in VAP incidence to values previously considered unreachable. Better compliance with clinical practice guidelines has resulted in VAP rates approaching zero in multiple studies. Faced with the measures recommended in these guidelines, selective digestive decontamination (SDD), used together with other infection control practices, has shown efficacy in hospitals with high baseline incidence of pneumonia. However, its effectiveness in hospitals with good compliance of clinical practice guidelines and lower rates of VAP is highly unlikely. A serious drawback of DDS is the risk of favoring the selection of resistant microorganisms that can spread easily through the ICU and the hospital. With current standards of infection prevention, DDS is an unnecessary and risky measure, which should not be used on a widespread basis. Those situations in which the DDS may increase the effectiveness of properly implemented standard measures are still unknown.

Abstract
PURPOSE Pneumonia associated with invasive mechanical ventilation (IMV) is one of the indicator infections of the German Nosocomial Infection Surveillance System. In 2005 surveillance was extended to include pneumonia associated with noninvasive ventilation (NIV). The aim of this study was to determine the utilization of IMV and NIV and the associated incidence densities (IDs) of pneumonia and to compare the characteristics of pneumonia cases and the spectrum of associated pathogens. METHODS We analyzed the pooled data of 400 intensive care units (ICUs) with respect to three categories of pneumonia: pneumonia associated with IMV and NIV and pneumonia not associated with ventilation. Pooled ventilation utilization rates and pneumonia IDs were calculated in total and stratified by hospital size, hospital type and ICU type. RESULTS Four hundred ICUs with 779,500 admitted patients, 1,068,472 IMV days and 101,569 NIV days reported 6,869 cases of pneumonia between 2005 and 2007. Of these, 5,811 cases were associated with IMV, 160 with NIV and 898 were not associated with ventilation. The mean pneumonia IDs were 1.58 and 5.44 cases per 1,000 ventilator days for NIV and IMV, respectively. Pneumonia cases associated with IMV were younger, had a longer ICU stay before onset of pneumonia and were more often associated with gram-negative bacteria than cases associated with NIV; however, there were no differences in the proportion of secondary sepsis and death. CONCLUSIONS This surveillance study including pneumonia associated with IMV and NIV and pneumonia not associated with ventilation shows significant differences of pneumonia IDs, patient characteristics and the spectrum of associated pathogens.

Abstract
BACKGROUND "Implementation research" promotes the systematic conversion of evidence-based principles into routine practice to improve the quality of care. We hypothesized a system-based initiative to reduce nosocomial infection would lower the incidence of ventilator-associated pneumonia (VAP), urinary tract infection (UTI), and bloodstream infection (BSI). METHODS From January 2006 to April 2008, 7,364 adult trauma patients were admitted, of which 1,953 (27%) were admitted to the trauma intensive care unit and comprised the study group. Tight glycemic control was maintained using a computer algorithm for continuous insulin administration based on every 2-hour blood glucose testing. Centers for Disease Control and Prevention definitions of nosocomial infections were used. Evidence-based infection reduction strategies included the following: a VAP bundle (spontaneous breathing, Richmond Agitation-Sedation Scale, oral hygiene, bed elevation, and deep vein thrombosis/stress ulcer prophylaxis), UTI (expert insertion team and Foley removal/change at 5 days), and BSI (maximum barrier precautions, chlorhexidine skin prep, line management protocol). An electronic dashboard identified the at-risk population, and designated auditors monitored the compliance. Infection rates (events per 1,000 device days) were measured over time and compared annually using Fisher's exact test. RESULTS The study group had 22,928 device exposure days: 6,482 ventilator days, 9,037 urinary catheter days, and 7,399 central line days. Patient acuity, demographics, and number of device days did not vary significantly year-to-year. Annual infection rates declined between 2006 and 2008, and decreases in UTI and BSI rates were statistically significant (p < 0.05). These decreases pushed UTI and BSI rates below Centers for Disease Control and Prevention norms. CONCLUSIONS Over 28 months, a systems approach to reducing nosocomial infection rates after trauma decreased nosocomial infections: UTI (76.3%), BSI (74.1%), and VAP (24.9%). Our experience suggests that infection reduction requires (1) an evidence-based plan; (2) MD and staff education/commitment; (3) electronic documentation; and (4) auditors to monitor and ensure compliance.

Abstract
BACKGROUND Ventilator-associated pneumonia (VAP) is a nosocomial pneumonia that develops in patients on mechanical ventilation for >or=48 hours. VAP develops at an estimated rate of 1% to 3% per day of mechanical ventilation. METHODS Quality improvement project. Mechanically ventilated patients received the following oral care every 4 hours: the teeth were brushed with cetylpyridinium chloride (changed to 0.12% chlorhexidine gluconate in 2007) using a suction toothbrush, the oral cavity was cleansed with suction swabs treated with hydrogen peroxide, a mouth moisturizer was applied, deep oropharyngeal suctioning was performed, and suction catheters were used to control secretions. The primary efficacy variable was a diagnosis of VAP in patients mechanically ventilated for >or=48 hours. RESULTS The historical average rate of VAP in 2004 was 12.6 cases/1000 ventilator-days. After the inception of the quality improvement project, VAP rates decreased to 4.12 (VAP cases/days of ventilation x 1000) for May to December 2005, to 3.57 for 2006, and to 1.3 for 2007. CONCLUSION The use of an oral care protocol intervention and ventilator bundle led to an 89.7% reduction in the VAP rate in mechanically ventilated patients from 2004 to 2007.

Abstract
Hospital-acquired pneumonia (HAP) is one of the most common causes of nosocomial infection, morbidity, and mortality in hospitalized patients. Many patient- and disease-specific factors contribute to the pathophysiology of HAP, particularly in the surgical population. Risk-factor modification and inpatient prevention strategies can have a significant impact on the incidence of HAP. While the best diagnostic strategy remains a subject of some debate, prompt and appropriate antimicrobial therapy in patients suspected of having HAP has been shown to significantly decrease mortality. Because the pathogens responsible for HAP are frequently more virulent and have greater resistance to commonly used antimicrobials than other pathogens, clinicians must have knowledge of the resistance patterns at their institutions to choose appropriate therapy.

Abstract
AIMS The aims of this study were to measure the levels of bile acids in patients with suspected ventilator-associated pneumonia (VAP) and provide a possible pathway for neutrophilic inflammation to explain its proinflammatory effect on the airway. METHODS Bile acid levels were measured by spectrophotometric enzymatic assay, and liquid chromatography mass spectrometry was used to quantify the major bile acids. Alveolar cells were grown on modified air-liquid interface culture inserts, and bile acids were then employed to stimulate the cells. Reverse transcriptase polymerase chain reaction and Western blots were used to determine the involved gene expression and protein levels. RESULTS The mean (+/- SE) concentration of total bile acids in tracheal aspirates was 6.2 +/- 2.1 and 1.1 +/- 0.4 mumol/L/g sputum, respectively, for patients with and without VAP (p < 0.05). The interleukin (IL)-8 level was significantly higher in the VAP group (p < 0.05). The major bile acid, chenodeoxycholic acid, stimulated alveolar epithelial cells to increase IL-8 production at both the messenger RNA and protein level through p38 and c-Jun N-terminal kinase (JNK) activation. The selective p38 and JNK inhibitors, as well as dexamethasone, successfully inhibited IL-8 production. CONCLUSION These data suggest that early intervention to prevent bile acid aspiration may reduce the intensity of neutrophilic inflammation in intubated and mechanically ventilated patients in the ICU.
