Hurley J. Rebound Inverts the Staphylococcus aureus Bacteremia Prevention Effect of Antibiotic Based Decontamination Interventions in ICU Cohorts with Prolonged Length of Stay. Antibiotics (Basel) 2024; 13:316. [PMID: 38666992 PMCID: PMC11047347 DOI: 10.3390/antibiotics13040316] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/25/2024] [Revised: 03/25/2024] [Accepted: 03/28/2024] [Indexed: 04/29/2024] Open
Abstract
Could rebound explain the paradoxical lack of prevention effect against Staphylococcus aureus blood stream infections (BSIs) with antibiotic-based decontamination intervention (BDI) methods among studies of ICU patients within the literature? Two meta-regression models were applied, each versus the group mean length of stay (LOS). Firstly, the prevention effects against S. aureus BSI [and S. aureus VAP] among 136 studies of antibiotic-BDI versus other interventions were analyzed. Secondly, the S. aureus BSI [and S. aureus VAP] incidence in 268 control and intervention cohorts from studies of antibiotic-BDI versus that among 165 observational cohorts as a benchmark was modelled. In model one, the meta-regression line versus group mean LOS crossed the null, with the antibiotic-BDI prevention effect against S. aureus BSI at mean LOS day 7 (OR 0.45; 0.30 to 0.68) inverted at mean LOS day 20 (OR 1.7; 1.1 to 2.6). In model two, the meta-regression line versus group mean LOS crossed the benchmark line, and the predicted S. aureus BSI incidence for antibiotic-BDI groups was 0.47; 0.09-0.84 percentage points below versus 3.0; 0.12-5.9 above the benchmark in studies with 7 versus 20 days mean LOS, respectively. Rebound within the intervention groups attenuated and inverted the prevention effect of antibiotic-BDI against S. aureus VAP and BSI, respectively. This explains the paradoxical findings.

Abstract
Nosocomial pneumonia, or hospital-acquired pneumonia (HAP), and ventilator-associated pneumonia (VAP) are important health problems worldwide, with both being associated with substantial morbidity and mortality. HAP is currently the main cause of death from nosocomial infection in critically ill patients. Although guidelines for the approach to this infection model are widely implemented in international health systems and clinical teams, information continually emerges that generates debate or requires updating in its management. This scientific manuscript, written by a multidisciplinary team of specialists, reviews the most important issues in the approach to this important infectious respiratory syndrome, and it updates various topics, such as a renewed etiological perspective for updating the use of new molecular platforms or imaging techniques, including the microbiological diagnostic stewardship in different clinical settings and using appropriate rapid techniques on invasive respiratory specimens. It also reviews both Intensive Care Unit admission criteria and those of clinical stability to discharge, as well as those of therapeutic failure and rescue treatment options. An update on antibiotic therapy in the context of bacterial multiresistance, in aerosol inhaled treatment options, oxygen therapy, or ventilatory support, is presented. It also analyzes the out-of-hospital management of nosocomial pneumonia requiring complete antibiotic therapy externally on an outpatient basis, as well as the main factors for readmission and an approach to management in the emergency department. Finally, the main strategies for prevention and prophylactic measures, many of them still controversial, on fragile and vulnerable hosts are reviewed.

Frequency of ventilator circuit changes to prevent ventilator-associated pneumonia in neonates and children-A systematic review and meta-analysis. Pediatr Pulmonol 2021; 56:1357-1365. [PMID: 33713572 DOI: 10.1002/ppul.25345] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/03/2021] [Revised: 02/08/2021] [Accepted: 02/22/2021] [Indexed: 11/06/2022]
Abstract
OBJECTIVE To assess the effect of different frequencies of ventilator circuit changes in neonates and children through a systematic review and meta-analysis. INTERVENTIONS (1) "No routine change of ventilator circuit (unless visibly soiled)" versus "routine change at any fixed interval"; (2) routine change of circuit at "less frequent" versus "more frequent" intervals. OUTCOMES Primary outcomes were VAP rate (number of VAP episodes per 1000 ventilator-days) and all-cause mortality before discharge. METHODS MEDLINE, CENTRAL, EMBASE, and CINAHL were systematically searched from inception till November 3, 2020. Two authors assessed trial eligibility and risk of bias, and independently extracted data. Data were synthesized using fixed effects model. GRADE was used to assess certainty of evidence (CoE). RESULTS We identified six studies enrolling 768 participants evaluating circuit changes at two fixed intervals. Meta-analysis of studies on circuit changes "once in less than 7 days" versus "once weekly" showed no difference in VAP rate (risk ratio: 0.83 [0.38-1.81]; one randomized controlled trial (RCT) and 0.94 [0.49-1.81]; two before-after studies) or mortality before discharge (0.67 [0.34-1.3]; one RCT and 1.01 [0.63-1.64]; two before-after studies). CoE was very low. Less frequent circuit changes reduced health-care costs. No study evaluating "circuit changes only when visibly soiled" versus "circuit changes at a fixed interval" was identified. CONCLUSION There is no evidence to suggest that ventilator circuits can be safely left unchanged until visibly soiled in neonates and children. Extending circuit changes interval to "once weekly" may not increase VAP rate (CoE-very low) and reduces healthcare costs.

Unusually High Incidences of Staphylococcus aureus Infection within Studies of Ventilator Associated Pneumonia Prevention Using Topical Antibiotics: Benchmarking the Evidence Base. Microorganisms 2018; 6:microorganisms6010002. [PMID: 29300363 PMCID: PMC5874616 DOI: 10.3390/microorganisms6010002] [Citation(s) in RCA: 16] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/07/2017] [Revised: 12/29/2017] [Accepted: 01/02/2018] [Indexed: 01/08/2023] Open
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/AIM The aim of this study was to investigate the epidemiologic characteristics, the causative microorganisms and their antimicrobial susceptibility patterns, and the prognostic risk factors for mortality in critically ill patients with ventilator-associated pneumonia (VAP). MATERIALS AND METHODS In this retrospective observational study, all the critically ill patients with VAP hospitalized in a medical/surgical intensive care unit (ICU) between January 2010 and June 2015 were evaluated. Patients' demographic features and microbiological data were reviewed. RESULTS A total of 417 patients were clinically diagnosed with VAP; 51.1% of them were male and the average age was found as 69.9 ± 15.9 years. VAP was detected at approximately 25.0 ± 18.0 days of ICU stay and 17.9 ± 12.6 days after intubation. Acinetobacter baumannii (69.5%) was isolated as the most frequent VAP agent, and the most effective antibiotic was colistin. The crude mortality rate was detected as 39.8% among the patients. The presence of dyspnea at admission, coronary heart disease as a comorbidity, unconsciousness at admission, steroid usage, and prolonged hospital stay were observed as independent risk factors in multivariate analysis (P < 0.01). CONCLUSION According to the etiological microorganisms and antimicrobial susceptibility patterns, colistin was found to be the most reliable antibiotic for empirical antimicrobial therapy.

Abstract
Mechanical ventilator use is fraught with risk of complications. Ventilator-associated pneumonia (VAP) is a common complication that prolongs stays on the ventilator and increases mortality and costs. The Centers for Disease Control and Prevention recommend the use of the term, ventilator-associated event. Prevention and/or interruption of cycle of inflammation, colonization of respiratory tract, and ventilator-associated tracheobronchitis are key to managing VAP. Modifying risk factors using a ventilator bundle is considered standard of care. The contentious factors and the lack of support for early tracheotomy, parenteral nutrition, and monitoring of gastric residuals are also addressed. Finally, the role of ventilator-associated tracheobronchitis in VAP is discussed.

Abstract
Background Moisturizing, heating and filtering gases inspired via the mechanical ventilation (MV) circuits help to reduce the adverse effects of MV. However, there is still no consensus regarding whether these measures improve patient prognosis, shorten MV duration, decrease airway secretion and lower the incidence of ventilator associated pneumonia (VAP) and other complications. Objectives The aim of this study was to study the incremental cost-effectiveness ratio associated with the use of heat and moisture exchangers (HME) filter to prevent VAP compared with the heated humidifiers (HH) presently adopted by intensive care unit (ICU) services within the Brazilian Healthcare Unified System. Patients and Methods This study was a cost-effectiveness analysis (CEA) comparing HME and HH in preventing VAP (outcome) in mechanically ventilated adult patients admitted to an ICU of a public university hospital. Results The analysis considered a period of 12 months; MV duration of 11 and 12 days for patients in HH and HME groups, respectively and a daily cost of R$ 16.46 and R$ 13.42 for HH and HME, respectively. HME was more attractive; costs ranged from R$ 21,000.00 to R$ 22,000.00 and effectiveness was close to 0.71, compared with a cost of R$ 30,000.00 and effectiveness between 0.69 and 0.70 for HH. HME and HH differed significantly for incremental effectiveness. Even after an effectiveness gain of 1.5% in favor of HH, and despite the wide variation in the VAP rate, the HME effectiveness remained stable. The mean HME cost-effectiveness was lower than the mean HH cost-effectiveness, being the HME value close to R$ 44,000.00. Conclusions Our findings revealed that HH and HME differ very little regarding effectiveness, which makes interpretation of the results in the context of clinical practice difficult. Nonetheless, there is no doubt that HME is advantageous. This technology incurs lower direct cost.

Abstract
The purpose here is to establish the incidence of respiratory tract colonization with Candida (RT Candida) among ICU patients receiving mechanical ventilation within studies in the literature. Also of interest is its relationship with candidemia and the relative importance of topical antibiotic (TA) use as within studies of selective digestive decontamination (SDD) versus other candidate risk factors towards it. The incidence of RT Candida was extracted from component (control and intervention) groups decanted from studies of various TA and non-TA ICU infection prevention methods with summary estimates derived using random effects. A benchmark RT Candida incidence to provide overarching calibration was derived using (observational) groups from studies without any prevention method under study. A multi-level regression model of group level data was undertaken using generalized estimating equation (GEE) methods. RT Candida data were sourced from 113 studies. The benchmark RT Candida incidence is 1.3; 0.9-1.8 % (mean and 95 % confidence intervals). Membership of a concurrent control group of a study of SDD (p = 0.02), the group-wide presence of candidemia risk factors (p < 0.001), and proportion of trauma admissions (p = 0.004), but neither the year of study publication, nor membership of any other component group, nor the mode of respiratory sampling are predictive of the RT Candida incidence. RT Candida and candidemia incidences are correlated. RT Candida incidence can serve as a basis for benchmarking. Several relationships have been identified. The increased incidence among concurrent control groups of SDD studies cannot be appreciated in any single study examined in isolation.

Abstract
Perspectives on invasive and noninvasive ventilatory support for critically ill
patients are evolving, as much evidence indicates that ventilation may have positive
effects on patient survival and the quality of the care provided in intensive care
units in Brazil. For those reasons, the Brazilian Association of Intensive Care
Medicine (Associação de Medicina Intensiva Brasileira - AMIB) and
the Brazilian Thoracic Society (Sociedade Brasileira de Pneumologia e
Tisiologia - SBPT), represented by the Mechanical Ventilation Committee
and the Commission of Intensive Therapy, respectively, decided to review the
literature and draft recommendations for mechanical ventilation with the goal of
creating a document for bedside guidance as to the best practices on mechanical
ventilation available to their members. The document was based on the available
evidence regarding 29 subtopics selected as the most relevant for the subject of
interest. The project was developed in several stages, during which the selected
topics were distributed among experts recommended by both societies with recent
publications on the subject of interest and/or significant teaching and research
activity in the field of mechanical ventilation in Brazil. The experts were divided
into pairs that were charged with performing a thorough review of the international
literature on each topic. All the experts met at the Forum on Mechanical Ventilation,
which was held at the headquarters of AMIB in São Paulo on August 3 and 4, 2013, to
collaboratively draft the final text corresponding to each sub-topic, which was
presented to, appraised, discussed and approved in a plenary session that included
all 58 participants and aimed to create the final document.

Abstract
BACKGROUND Acinetobacter baumannii is a leading cause of ventilator-associated pneumonia, often as a result of ventilator equipment contamination. Evidence-based guidance on optimal care of ventilator equipment to prevent infection is lacking. Here, we report on a significant and persistent reduction in A baumannii infection rates achieved by introducing a strict policy on ventilator care. METHODS We implemented an institution-wide ventilator care policy that included routine exchange of breathing circuits and external bacterial filters (every 7-14 days) and replacement followed by routine sterilization of internal bacterial filters (every 4-8 weeks). We analyzed sputum cultures and patient outcomes among ventilated patients before and after the intervention. RESULTS Between January 2012 and March 2013, 321 patients ventilated for more than 3 days comprised the study cohort. Health care-associated A baumannii acquisition was significantly reduced during the postintervention period (33% vs 16%; odds ratio, 0.39; 95% confidence interval, 0.23-0.67; P = .0008). Additionally, the median time to A baumannii acquisition was significantly longer postintervention (59 vs 21 days; P < .0001). A baumannii ventilator-associated pneumonia risk was also reduced postintervention (odds ratio, 0.39; P = .005). CONCLUSIONS Implementing a stricter standard of ventilator care than that currently defined in published guidelines can significantly decrease health care-associated A baumannii acquisition and related adverse outcomes among ventilated patients.

Abstract
Ventilator-associated pneumonia (VAP) is the most frequent and severe infection acquired in the intensive care unit, leading to prolonged mechanical ventilation and excess mortality. This article reviews the different aspects of VAP, such as risk factors, causative agents, and approaches to diagnosis, treatment, and prevention. Several aspects of VAP are still considered controversial.

Ventilator-associated pneumonia with or without toothbrushing: a randomized controlled trial. Eur J Clin Microbiol Infect Dis 2012; 31:2621-9.

Abstract
Certain guidelines for the prevention of ventilator-associated pneumonia (VAP) recommend oral care with chlorhexidine, but none refer to the use of a toothbrush for oral hygiene. The role of toothbrush use has received scant attention. Thus, the objective of this study was to compare the incidence of VAP in critical care patients receiving oral care with and without manual brushing of the teeth. This was a randomized clinical trial developed in a 24-bed medical-surgical intensive care unit (ICU). Patients undergoing invasive mechanical ventilation for than 24 h were included. Patients were randomly assigned to receive oral care with or without toothbrushing. All patients received oral care with 0.12 % chlorhexidine digluconate. Tracheal aspirate samples were obtained during endotracheal intubation, then twice a week, and, finally, on extubation. There were no significant differences between the two groups of patients in the baseline characteristics. We found no statistically significant differences between the groups regarding the incidence of VAP (21 of 217 [9.7 %] with toothbrushing vs. 24 of 219 [11.0 %] without toothbrushing; odds ratio [OR] = 0.87, 95 % confidence interval [CI] = 0.469-1.615; p = 0.75). Adding manual toothbrushing to chlorhexidine oral care does not help to prevent VAP in critical care patients on mechanical ventilation.

Abstract
BACKGROUND Ventilator-associated pneumonia (VAP) is a common clinical problem. Previous studies involving adult patient cohorts have assessed various risk factors associated with VAP, including ventilator circuit changes. The objective of this study was to examine the incidence of and risk factors associated with VAP, particularly 3-day versus 7-day ventilator circuit changes, in a pediatric intensive care unit (PICU). METHODS This was a cohort observational study. Patients hospitalized in the PICU at Chang Gung Children's Hospital between November 2003 and September 2004 were enrolled. Investigators and critical-care specialists evaluated baseline characteristics, incidence of VAP, and related variables from PICU admission until discharge or death. RESULTS Of 397 patients initially enrolled, 96 (aged 11-60 months) were available for statistical analysis and were assigned into two groups according to timing of ventilator circuit change: 3-day (n = 46) and 7-day circuit change (n = 50). No statistically significant differences were observed for VAP incidence (13% vs. 16%, p = 0.68) or hospital mortality (22% vs. 36%, p = 0.14) for 3-day versus 7-day circuit change. Incidence of VAP per 1000 ventilation days was 10.75 and 8.41 for 3-day and 7-day circuit change, respectively. Univariate analysis indicated statistical significance for the duration of mechanical ventilation (10.17 +/- 16.63 days vs. 18.20 +/- 14.99 days, p < 0.001), length of stay in PICU (22.30 +/- 20.48 days vs. 37.22 +/- 36.79 days, p = 0.0069) and presence of enteral nutrition [7 (15.22%) vs. 23 (46.0%), p = 0.0012]. CONCLUSION Weekly circuit change does not contribute to increased rates of VAP in pediatric patients. Long-term studies evaluating risk factors in larger pediatric patient populations are warranted for further conclusive recommendations.

Abstract
These evidence-based guidelines have been produced after a systematic literature review of a range of issues involving prevention, diagnosis and treatment of hospital-acquired pneumonia (HAP). Prevention is structured into sections addressing general issues, equipment, patient procedures and the environment, whereas in treatment, the structure addresses the use of antimicrobials in prevention and treatment, adjunctive therapies and the application of clinical protocols. The sections dealing with diagnosis are presented against the clinical, radiological and microbiological diagnosis of HAP. Recommendations are also made upon the role of invasive sampling and quantitative microbiology of respiratory secretions in directing antibiotic therapy in HAP/ventilator-associated pneumonia.

Abstract
As the most recent guidelines for the prevention of ventilator-associated pneumonia (VAP) were published four years ago, we have conducted a systematic review to discover whether the recently published articles should further influence existing guidelines. Articles published since 2004 dealing with infection control measures for prevention of VAP were gathered and evaluated in order to identify evidence for the possible modification of routine practice. Special emphasis was placed on randomized controlled trials (RCTs), meta-analyses or systematic reviews and studies applying multi-module interventions. A total of 15 RCTs and seven meta-analyses or systematic reviews were found. In addition to these, five cohort studies were identified where multi-module programmes were introduced for reducing VAP rates. The data lead to the conclusion that topical use of chlorhexidine for oral care is beneficial and subglottic secretion drainage may lead to delayed onset of VAP. The remaining studies had only a minor influence on existing guidelines for the prevention of VAP and confirmed the earlier recommendations in several points. However, the studies investigating multi-module programmes led to a substantial reduction of VAP of between 31 and 57%. The data show that many VAP cases are preventable and that there is room for improvement in many institutions. Often simple interventions are useful for the reduction of VAP rates, for which the best chances appeared to be the application of multi-module programmes. On average a reduction of more than 40% seems to be possible.
