Clinical, Microbiological and Treatment Characteristics of Severe Postoperative Respiratory Infections: An Observational Cohort Study. J Pers Med 2023; 13:1482. [PMID: 37888093 PMCID: PMC10608667 DOI: 10.3390/jpm13101482] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/12/2023] [Revised: 10/02/2023] [Accepted: 10/07/2023] [Indexed: 10/28/2023] Open
Abstract
Respiratory infections are frequent and life-threatening complications of surgery. This study aimed to evaluate the clinical, microbiological and treatment characteristics of severe postoperative pneumonia (POP) and tracheobronchitis (POT) in a large series of patients. This single-center, prospective observational cohort study included patients with POP or POT requiring intensive care unit admission in the past 10 years. We recorded demographic, clinical, microbiological and therapeutic data. A total of 207 patients were included, and 152 (73%) were men. The mean (SD) age was 70 (13) years and the mean (SD) ARISCAT score was 46 (19). Ventilator-associated pneumonia was reported in 21 patients (10%), hospital-acquired pneumonia was reported in 132 (64%) and tracheobronchitis was reported in 54 (26%). The mean (SD) number of days from surgery to POP/POT diagnosis was 6 (4). The mean (SD) SOFA score was 5 (3). Respiratory microbiological sampling was performed in 201 patients (97%). A total of 177 organisms were cultured in 130 (63%) patients, with a high proportion of Gram-negative and multi-drug resistant (MDR) bacteria (20%). The most common empirical antibiotic therapy was a triple-drug regimen covering MDR Gram-negative bacteria and MRSA. In conclusion, surgical patients are a high-risk population with a high proportion of early onset severe POP/POT and nosocomial bacteria isolation.

[PMID: 35883250 PMCID: PMC10498383 DOI: 10.1093/cid/ciac616] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/13/2022] [Revised: 07/14/2022] [Accepted: 07/22/2022] [Indexed: 11/14/2022] Open
Abstract
BACKGROUND Suspected pneumonia is the most common indication for antibiotics in hospitalized patients but is frequently overdiagnosed. We explored whether normal oxygenation could be used as an indicator to support early discontinuation of antibiotics. METHODS We retrospectively identified all patients started on antibiotics for pneumonia in 4 hospitals with oxygen saturations ≥95% on ambient air, May 2017-February 2021. We propensity-matched patients treated 1-2 days vs 5-8 days and compared hospital mortality and time to discharge using subdistribution hazard ratios (SHRs). Secondary outcomes included readmissions, 30-day mortality, Clostridioides difficile infections, hospital-free days, and antibiotic-free days. RESULTS Among 39 752 patients treated for possible pneumonia, 10 012 had median oxygen saturations ≥95% without supplemental oxygen. Of these, 2871 were treated 1-2 days and 2891 for 5-8 days; 4478 patients were propensity-matched. Patients treated 1-2 vs 5-8 days had similar hospital mortality (2.1% vs 2.8%; SHR, 0.75 [95% confidence interval {CI}, .51-1.09]) but less time to discharge (6.1 vs 6.6 days; SHR, 1.13 [95% CI, 1.07-1.19]) and more 30-day hospital-free days (23.1 vs 22.7; mean difference, 0.44 [95% CI, .09-.78]). There were no significant differences in 30-day readmissions (16.0% vs 15.8%; odds ratio [OR], 1.01 [95% CI, .86-1.19]), 30-day mortality (4.6% vs 5.1%; OR, 0.91 [95% CI, .69-1.19]), or 90-day C. difficile infections (1.3% vs 0.8%; OR, 1.67 [95% CI, .94-2.99]). CONCLUSIONS One-quarter of hospitalized patients treated for pneumonia had oxygenation saturations ≥95% on ambient air. Outcomes were similar with 1-2 vs 5-8 days of antibiotics. Normal oxygenation levels may help identify candidates for early antibiotic discontinuation. Prospective trials are warranted.

Abstract
BACKGROUND AND AIMS Postoperative pulmonary complications are frequent after hepatectomy. The aim of this retrospective study was to use preoperative and intraoperative data to establish specific factors associated with post-hepatectomy pneumonia (PHPN). METHODS Patients underwent minor or major hepatectomy for cancer or non-cancer treatment. Surgical procedure was performed by laparoscopy or laparotomy. PHPN was defined as a new radiologic finding associated with fever, leucocytosis and purulent bronchial secretions. The incidence, associated factors and prognosis of PHPN were investigated. RESULTS In 399 patients undergoing planned hepatectomy, 49 (12.3%) developed pneumonia. Of 81 patients (20.3%) with cirrhosis, 77 were Child-Pugh A and 4 were Child-Pugh B. Hepatectomy indication was cancer in 331 patients (of which metastasis in 213). Laparoscopy rate was 31.3%. In multivariate analysis, the main factors statistically associated with PHPN were: chronic obstructive pulmonary disease (COPD) (odds ratio [OR] = 4.17; 95% confidence interval [CI], 1.60-10.84; P = 0.003), intraoperative blood transfusion (OR = 2.46; 95% CI 1.01-5.70; P = 0.001), laparotomy (OR = 3.01; 95% CI 1.09-8.27; P = 0.03), and nasogastric tube maintained at day 1 (OR = 2.09; 95% CI 1.03-4.22; P = 0.04). Length of stay was significantly different between groups without PHPN (10.2 days) versus with PHPN (26.4 days; P < 0.001). Intra-hospital and one-year mortality were greater in the PHPN group than the pneumonia-free group (8.16 vs 0% and 18.4 vs 3.4%, respectively; P < 0.001). CONCLUSIONS COPD, transfusion and laparotomy (versus laparoscopy) are factors associated with PHPN and impaired survival.

Abstract
Hospital-acquired pneumonia (HAP) and ventilator-associated pneumonia (VAP) continue to be major concerns for morbidity and mortality, especially in patients treated in the intensive care unit. With the rise in multidrug-resistant organisms, HAP and VAP treatment is challenged by the need for early appropriate treatment, with broad-spectrum agents, while still being aware of the principles of antibiotic stewardship. The two major society guidelines proposed a series of risk factors in their most recent guidelines to help identify patients who can most benefit from narrow- or broad-spectrum initial empiric antibiotic therapy. The guidelines reveal differences in the proposed risk factors and treatment approaches, as well as major similarities.

Abstract
Introduction: Routine preoperative testing for low-risk surgeries without a clinical indication should be avoided; however, such tests are still frequently performed in Japan. This study was performed to assess the impact of routine preoperative tests in low-risk surgery in a Japanese medical setting. Methods: We performed a retrospective chart review to examine the utility of routine tests with respect to anesthetic management and postoperative complications in all patients aged ≥ 18 years whom ophthalmologists consulted with anesthesiologists before ophthalmologic surgery under general anesthesia. Results: During the 10-year study period, 1,234 anesthetic consultations and 1,211 routine preoperative tests (laboratory tests, chest X-rays, and electrocardiograms) were performed in Toyama University Hospital. In total, 59 patients (4.8% of the study population) canceled surgery after a battery of preoperative evaluation. Among them, 10 patients had incidental abnormalities that necessitated additional tests, and only three patients (0.2%) canceled surgery. In-hospital postoperative complications developed in nine patients (0.7%) whose routine test results made it difficult to predict development of these adverse events. No severe life-threatening events were noted in this survey. Conclusions: Routine tests prior to eye surgery for adults were of low value for perioperative management and prediction of development of in-hospital complications in this Japanese medical setting. Anesthesiologists and ophthalmologists should selectively order preoperative tests based on the medical interview and physical examination.

Abstract
Antibiotic combination therapies are important for the efficient treatment of many types of infections, including those caused by antibiotic-resistant pathogens. Combination treatment strategies are typically used under the assumption that synergies are conserved across species and strains, even though recent results show that the combined treatment effect is determined by specific drug–strain interactions that can vary extensively and unpredictably, both between and within bacterial species. To address this problem, we present a new method in which antibiotic synergy is rapidly quantified on a case-by-case basis, allowing for improved combination therapy. The novel CombiANT methodology consists of a 3D-printed agar plate insert that produces defined diffusion landscapes of 3 antibiotics, permitting synergy quantification between all 3 antibiotic pairs with a single test. Automated image analysis yields fractional inhibitory concentration indices (FICis) with high accuracy and precision. A technical validation with 3 major pathogens, Escherichia coli, Pseudomonas aeruginosa, and Staphylococcus aureus, showed equivalent performance to checkerboard methodology, with the advantage of strongly reduced assay complexity and costs for CombiANT. A synergy screening of 10 antibiotic combinations for 12 E. coli urinary tract infection (UTI) clinical isolates illustrates the need for refined combination treatment strategies. For example, combinations of trimethoprim (TMP) + nitrofurantoin (NIT) and TMP + mecillinam (MEC) showed synergy, but only for certain individual isolates, whereas MEC + NIT combinations showed antagonistic interactions across all tested strains. These data suggest that the CombiANT methodology could allow personalized clinical synergy testing and large-scale screening. We anticipate that CombiANT will greatly facilitate clinical and basic research of antibiotic synergy. Existing methods for identifying efficient combinations of antibiotics are time-consuming and costly, restricting their use in clinics and research. This study describes the novel CombiANT methodology, which uses defined diffusion landscapes of three antibiotics to permit rapid and low-cost synergy quantification between all antibiotic pairs.

Abstract
BACKGROUND Stenotrophomonas maltophilia (SM) is increasingly identified in intensive care unit (ICU). This study aim to identify risk factors for SM ventilator-associated pneumonia (VAP) and whether it affects ICU mortality METHODS: Two nested matched case-control studies were performed based in OUTCOMEREA database. The first episodes of SM-VAP patients were matched with two different control groups: VAP due to other micro-organisms (VAP-other) and Pseudomonas aeruginosa VAP (Pyo-VAP). Matching criteria were the hospital, the SAPS II, and the previous duration of mechanical ventilation (MV). RESULTS Of the 102 SM-VAP patients (6.2% of all VAP patients), 92 were matched with 375 controls for the SM-VAP/other-VAP matching and 84 with 237 controls for the SM-VAP/Pyo-VAP matching. SM-VAP risk factors were an exposition to ureido/carboxypenicillin or carbapenem during the week before VAP, and respiratory and coagulation components of SOFA score upper to 2 before VAP. SM-VAP received early adequate therapy in 70 cases (68.6%). Risk factors for Day-30 were age (OR = 1.03; p < 0.01) and Chronic heart failure (OR = 3.15; p < 0.01). Adequate treatment, either monotherapy or combination of antimicrobials, did not modify mortality. There was no difference in 30-day mortality, but 60-day mortality was higher in patients with SM-VAP compared to Other-VAP (P = 0.056). CONCLUSIONS In a large series, independent risk factors for the SM-VAP were ureido/carboxypenicillin or carbapenem exposure the week before VAP, and respiratory and coagulation components of the SOFA score > 2 before VAP. Mortality risk factors of SM-VAP were age and chronic heart failure. Adequate treatment did not improve SM-VAP prognosis.

Abstract
IMPORTANCE Hospital-acquired pneumonia is the most common health care-associated infection in the United States. Most cases occur in nonventilated patients, but many hospitals track hospital-acquired pneumonia only in ventilated patients because of the complexity and subjectivity of conducting surveillance for large numbers of nonventilated patients. OBJECTIVE To propose and assess potentially objective, efficient, and reproducible surveillance definitions for nonventilator hospital-acquired pneumonia (NV-HAP) using routine clinical data stored in electronic health record systems. DESIGN, SETTING, AND PARTICIPANTS This cohort study was conducted in 2 tertiary referral and 2 community hospitals in Massachusetts between May 31, 2015, and July 1, 2018. All nonventilated patients aged 18 years or older who were admitted to these hospitals were included (N = 310 651). EXPOSURES Ten candidate definitions for NV-HAP based on clinically meaningful combinations of 6 potential surveillance criteria were proposed: worsening oxygenation, temperature higher than 38 °C (fever), abnormal white blood cell count of less than 4000/μL or more than 12 000/μL, performance of chest imaging, submission of respiratory specimen for culture, and 3 or more days of new antibiotics. MAIN OUTCOMES AND MEASURES Incidence rates, lengths of stay, hospital mortality rates, and odds ratios (ORs) for time to discharge and mortality compared with those of matched controls were calculated for each candidate definition. The ORs were adjusted for demographics, clinical service, comorbidities, and severity of illness. RESULTS The study analyzed 310 651 patients with 489 519 admissions, including 205 054 patients with 311 484 admissions of 3 or more days. Among the patients with 311 484 admissions, the mean (SD) patient age was 58.3 (19.3) years and 176 936 (56.8%) were of women. Incidence rates for candidate definitions per 100 admissions ranged from 3.4 events for worsening oxygenation alone to 0.9 event for worsening oxygenation and at least 3 days of new antibiotics to 0.6 event for worsening oxygenation, at least 3 days of new antibiotics, fever, abnormal white blood cell count, and performance of chest imaging. Crude mortality rates ranged from 16.1% (n = 2643) for patients with worsening oxygen alone to 27.7% (n = 868) for patients with worsening oxygenation, at least 3 days of antibiotics, fever or abnormal white blood cell count, and chest imaging. Patients who met NV-HAP candidate definitions remained in the hospital for twice as long as their matched controls (adjusted ORs ranged from 1.8 [95% CI, 1.7-1.8] to 2.1 [95% CI, 2.0-2.1]) and were 4 to 6 times as likely to die in the hospital (adjusted ORs ranged from 3.8 [95% CI, 3.5-4.0] to 6.5 [95% CI, 5.2-8.2]). Agreement between candidate definitions and clinical diagnoses was fair (κ = 0.33). CONCLUSIONS AND RELEVANCE These findings suggest that objective surveillance for NV-HAP using electronically computable definitions that incorporate common clinical criteria is feasible and generates incidence, mortality, and adjusted ORs for hospital mortality similar to estimates from manual surveillance. These definitions have the potential to facilitate widespread, automated surveillance for NV-HAP and thus inform the development and evaluation of prevention programs.

Abstract
Antibiotic-resistant bacteria are a significant threat to human health, with one estimate suggesting they will cause 10 million worldwide deaths per year by 2050, surpassing deaths due to cancer1. Because new antibiotic development can take a decade or longer, it is imperative to effectively use currently available drugs. Antibiotic combination therapy offers promise for treating highly resistant bacterial infections, but the factors governing the sporadic efficacy of such regimens have remained unclear. Dogma suggests that antibiotics ineffective as monotherapy can be effective in combination2. Here, using carbapenem-resistant Enterobacteriaceae (CRE) clinical isolates, we reveal the underlying basis for the majority of effective combinations to be heteroresistance. Heteroresistance is a poorly understood mechanism of resistance reported for different classes of antibiotics3-6 in which only a subset of cells are phenotypically resistant7. Within an isolate, the subpopulations resistant to different antibiotics were distinct, and over 88% of CRE isolates exhibited heteroresistance to multiple antibiotics ('multiple heteroresistance'). Combinations targeting multiple heteroresistance were efficacious, whereas those targeting homogenous resistance were ineffective. Two pan-resistant Klebsiella isolates were eradicated by combinations targeting multiple heteroresistance, highlighting a rational strategy to identify effective combinations that employs existing antibiotics and could be clinically implemented immediately.

Abstract
INTRODUCTION Hospital-acquired pneumonia (HAP) is a potentially serious infection that primarily affects older patients. The number of patients affected by multidrug-resistant (MDR) bacteria is increasing, including infection from strains of Staphylococcus aureus, Enterobacteriaceae, and Pseudomonas aeruginosa. AREAS COVERED This article focuses specifically on HAP, excluding patients afflicted by ventilator-associated pneumonia (VAP). The pathogenesis and clinical features of HAP in the elderly are discussed as well as specific drug pharmacokinetic and pharmacodynamic considerations in elderly patients. The current recommended guidelines for the management of HAP are also discussed. Finally, the authors provide evidence on the empirical therapy used for the treatment of HAP and widely consider specific-pathogen treatment of HAP in elderly patients. EXPERT OPINION In patients not at risk of MDR organism infection, antibiotics including piperacillin-tazobactam, cefepime, carbapenems or fluorquinolones are recommended. However, the emergence of MDR organisms as causal agents of HAP makes it necessary to accurately assess risk factors to these pathogens and revise our knowledge on specific antimicrobial susceptibility patterns from each institution. The authors believe that broader-spectrum empiric antibiotic therapies that target P. aeruginosa and methicillin-resistant S. aureus are best recommended in elderly patients at risk of HAP infection by MDR strains.

World Neurosurg 2018; 122:e1312-e1320.

Abstract
BACKGROUND Colloid transfusion during surgical decompressive hemicraniectomy (DHC) to treat space-occupying cerebral infarction induced by middle cerebral artery (MCA) is controversial. A multicenter retrospective study was conducted to determine whether an increased colloid transfusion during surgery is associated with a lower incidence of postoperative pneumonia and better long-term outcomes after space-occupying cerebral infarction. METHODS Data from surgical DHC within 48 hours to treat space-occupying cerebral infarction that took place between November 30, 2013, and March 30, 2016, were collected in a multicenter chart. Univariate analysis, Spearman correlation, χ2 test, and bivariate and multivariate logistic regression were performed to account for the associations between colloid transfusion and postoperative pneumonia or long-term outcomes (indicated by modified Rankin Scale [mRS] scores). RESULTS Univariate analysis showed that surgical duration and mRS were significantly different between the subjects older and younger than 60 years who underwent surgical DHC (P < 0.05). In the entire population studied, increased National Institutes of Health Stroke Scale was associated with a greater incidence of postoperative pneumonia (odds ratio [OR] 1.255, P = 0.003) and increased mRS (OR 1.229, P = 0.014). In the population older than 60 years, it was revealed that increased colloid transfusion was associated with a lower incidence of postoperative pneumonia (OR 0.761, P = 0.030) or better outcomes, as indicated with lower mRS (OR 0.837, P = 0.045). CONCLUSIONS Our retrospective study demonstrated that there is a robust association between increased perioperative colloid transfusion and lower incidence of postoperative pneumonia and better outcomes among the patients older than 60 years after space-occupying cerebral infarction.

Abstract
PURPOSE OF REVIEW Hospital-acquired pneumonia (HAP) and ventilator-associated pneumonia (VAP) remain important causes of morbidity and mortality in hospitalized patients. New evidence-based guidelines for the diagnosis and treatment of these entities were released by the Infectious Diseases Society of America and the American Thoracic Society in 2016. This review summarizes the recommendations contained within these guidelines and their supporting rationale. RECENT FINDINGS With respect to diagnosis of HAP and VAP, the guidelines suggest using semiquantitative cultures of noninvasively obtained respiratory samples instead of quantitative cultures of invasively obtained samples. With respect to antibiotic treatment, the guidelines separate the treatment approach for VAP and HAP (non-VAP), and stress the importance of devising an appropriate empiric regimen based on an appropriate hospital or unit-specific antibiogram. For VAP, coverage of methicillin-resistant Staphylococcus aureus is recommended only when patients have specific risk factors for multidrug-resistant (MDR) pathogens or in units where greater than 10-20% of Staphylococcus aureus isolates are methicillin resistant. Single coverage for MDR gram-negative pathogens can be used in many HAP and VAP patients without risk factors for MDR pathogens when the antibiogram demonstrates that at least 90% of gram negatives are sensitive to the agent being considered for monotherapy. A 7-day course of antibiotics was recommended for most patients, including those with glucose nonfermenting gram-negative organisms. SUMMARY New guidelines for the diagnosis and treatment of HAP and VAP contain several novel recommendations regarding the diagnosis and treatment of these entities.

Abstract
BACKGROUND This study was conducted to observe the clinical efficacy of long-term piperacillin-tazobactam (TZP) infusion and identify the factors affecting its curative effect against pneumonia in patients who had undergone surgery for abdominal tumor. METHODS The 100 patients were divided into four clinical groups according to the severity of their infection: Simple pneumonia, pneumonia with pleural effusion, pneumonia and atelectasis, and severe pneumonia. Each group of patients was then divided into control and treatment groups using a completely random design. The control group received TZP as a regular infusion, and the treatment group received TZP as a long-term infusion. The cure time in the different groups was compared according to the administration regimen, and stratified analysis was carried out to identify the efficacy factors of long-term TZP infusion for patients with each kind of pneumonia. RESULTS The average cure time for TZP differed significantly among the groups. In particular, the average cure times in the simple pneumonia, pneumonia with pleural effusion, pneumonia and atelectasis, and severe pneumonia groups were 6.800 ± 0.342, 7.320 ± 0.304, 10.840 ± 0.571, and 15.942 ± 0.973 d (p < 0.001). In each group, the usage time of antibiotics in the treatment groups was significantly shorter than in the control group (8.87 ± 0.64 vs. 15.95 ± 2.02 d; p < 0.001). The cure times (d) for simple pneumonia and pneumonia and atelectasis were conspicuously lower in the treatment groups than in the control group (5.667 ± 0.256 vs. 7.846 ± 0.451; p < 0.001; 9.667 ± 1.432 vs. 11.923 ± 0.947; p = 0.024). The factors associated with continuous treatment effectiveness were being male, age <70 years, Acute Physiology and Chronic Health Evaluation score ≥17 points, minimum inhibitory concentration of the pathogen 8 mcg/mL, oxygenation index >200 mm Hg, serum procalcitonin concentration >4 ng/mL, and serum albumin <25 g/L. CONCLUSION Long-term TZP infusion exhibited better clinical efficacy than did traditional treatment in patients with pneumonia after abdominal tumor surgery.

Abstract
The ability of the emergency physician to recognize and manage a patient with a compromised airway is probably the most important aspect of an individual’s care in the emergency department. Endotracheal intubation in a critically ill patient is a potentially hazardous procedure because of the technical difficulties that can be encountered during emergency airway management and the profound pathophy siological changes that the institution of mechanical ventilation can cause. This review article sets out to illustrate when invasive airway management should be considered and the potential consequences of attempts to perform endotracheal intubation and mechanical ventilation.

Abstract
It is important to realize that guidelines cannot always account for individual variation among patients. They are not intended to supplant physician judgment with respect to particular patients or special clinical situations. IDSA considers adherence to these guidelines to be voluntary, with the ultimate determination regarding their application to be made by the physician in the light of each patient's individual circumstances.These guidelines are intended for use by healthcare professionals who care for patients at risk for hospital-acquired pneumonia (HAP) and ventilator-associated pneumonia (VAP), including specialists in infectious diseases, pulmonary diseases, critical care, and surgeons, anesthesiologists, hospitalists, and any clinicians and healthcare providers caring for hospitalized patients with nosocomial pneumonia. The panel's recommendations for the diagnosis and treatment of HAP and VAP are based upon evidence derived from topic-specific systematic literature reviews.

Abstract
Abstract
Background
Patients undergoing major vascular surgery often develop postoperative pneumonia that impacts their outcomes. Conflicting data exist concerning the potential benefit of tapered-shaped cuffs on tracheal sealing. The primary objective of this study was to assess the efficiency of a polyvinyl chloride tapered-cuff endotracheal tube at reducing the postoperative pneumonia rate after major vascular surgery. Secondary objectives were to determine its impact on microaspiration, ventilator-associated pneumonia rate, and inner cuff pressure.
Methods
This prospective randomized controlled study included 109 patients who were randomly assigned to receive either spherical- (standard cuff) or taper-shaped (tapered cuff) endotracheal tubes inserted after anesthesia induction and then admitted to the intensive care unit after major vascular surgery. Cuff pressure was continuously recorded over 5 h. Pepsin and α-amylase concentrations in tracheal aspirates were quantified on postoperative days 1 and 2. The primary outcome was the early postoperative pneumonia frequency.
Results
Comparing the tapered-cuff with standard-cuff group, respectively, postoperative pneumonia rates were comparable (42 vs. 44%, P = 0.87) and the percentage (interquartile range) of cuff-pressure time with overinflation was significantly higher (16.1% [1.5 to 50] vs. 0.6% [0 to 8.3], P = 0.01), with a 2.5-fold higher coefficient of variation (20.2 [10.6 to 29.4] vs. 7.6 [6.2 to 10.2], P < 0.001). Although microaspiration frequencies were high, they did not differ between groups.
Conclusion
For major vascular surgery patients, polyvinyl chloride tapered-cuff endotracheal tubes with intermittent cuff-pressure control did not lower the early postoperative pneumonia frequency and did not prevent microaspiration.

Abstract
UNLABELLED Hospital-acquired pneumonia (HAP) and health-care-associated pneumonia (HCAP) are leading causes of death, morbidity, and resource utilization in hospitalized patients, and are associated with a broad range of Gram-positive and Gram-negative pathogens. Here, we discuss the different definitions of HAP and HCAP, review current guidelines regarding the treatment of these conditions, highlight the shortcomings of current therapeutic options, and discuss new antibiotic treatments. To optimize therapeutic outcomes in patients with HAP/HCAP, initial antimicrobial treatment must be appropriate and should be given as soon as possible; inappropriate or delayed therapy greatly increases morbidity and mortality. Selection of the most appropriate antimicrobial agent depends on the causative pathogen(s); initial broad-spectrum therapy is commonly recommended and should cover all pathogens that may be present. Treatment selection should also take into consideration the following factors: knowledge of underlying local risk factors for antimicrobial resistance, disease staging, and risk factors related to specific pathogens such as Pseudomonas aeruginosa, Acinetobacter spp., and methicillin-resistant Staphylococcus aureus (MRSA). Guidelines consistently emphasize the importance of treating HAP and HCAP with early and appropriate broad-spectrum antibiotics, and recent developments in this field have resulted in the availability of several additional treatment options. Telavancin shows potent activity against Gram-positive bacteria including MRSA and can be administered once daily; it was approved in the USA and European Union for the treatment of HAP after demonstrating non-inferiority to vancomycin. Ceftobiprole medocaril exhibits rapid antimicrobial activity against a broad range of both Gram-positive and Gram-negative pathogens, including MRSA. It was approved for the treatment of HAP (excluding ventilator-associated pneumonia) and community-acquired pneumonia in Europe in 2013. These new treatments may offer effective alternative therapeutic options for the management of HAP. FUNDING Basilea Pharmaceutica Ltd., Basel, Switzerland.

Abstract
BACKGROUND The risk of post-operative pneumonia is a latent complication. A study was conducted to determine its risk factors in abdominal surgery. MATERIAL AND METHODS A cross-sectional study was performed that included analysing the variables of age and gender, chronic obstructive pulmonary disease and smoking, serum albumin, type of surgery and anaesthesia, emergency or elective surgery, incision site, duration of surgery, length of hospital stay, length of stay in the intensive care unit, and time on mechanical ventilation. The adjusted odds ratio for risk factors was obtained using multivariate logistic regression. RESULTS The study included 91 (9.6%) patients with pneumonia and 851 (90.4%) without pneumonia. Age 60 years or over (OR=2.34), smoking (OR=9.48), chronic obstructive pulmonary disease (OR=3.52), emergency surgery (OR=2.48), general anaesthesia (OR=3.18), surgical time 120 minutes or over (OR=5.79), time in intensive care unit 7 days or over (OR=1.23), time on mechanical ventilation greater than or equal to 4 days (OR=5.93) and length of post-operative hospital stay of 15 days or over (OR=1.20), were observed as independent predictors for the development of postoperative pneumonia. CONCLUSIONS Identifying risk factors for post-operative pneumonia may prevent their occurrence. The length in the intensive care unit of greater than or equal to 7 days (OR=1.23; 95% CI 1.07 - 1.42) and a length postoperative hospital stay of 15 days or more (OR=1.20; 95% CI 1.07 - 1.34) were the predictive factors most strongly associated with lung infection in this study.

[PMID: 25881186 PMCID: PMC4372228 DOI: 10.1186/s13054-015-0845-5] [Citation(s) in RCA: 17] [Impact Index Per Article: 1.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 12/23/2014] [Accepted: 03/02/2015] [Indexed: 11/10/2022]
Abstract
INTRODUCTION No studies have compared ventilator-associated pneumonia (VAP) and non-VAP following cardiac surgery (CS). The aim of this study was to assess the incidence, clinical and microbiologic features, treatment characteristics and prognosis of postoperative pneumonia following CS with a special focus on non-VAP. METHODS This was a retrospective cohort study based on a prospectively collected database. We compared cases of non-VAP and VAP following CS observed between January 2005 and December 2012. Statistical analysis consisted of bivariate and multivariate analysis. RESULTS A total of 257 (3.5%) of 7,439 consecutive CS patients developed postoperative pneumonia, including 120 (47%) cases of non-VAP. Patients with VAP had more frequent history of congestive heart failure (31% vs. 17%, P = 0.006) and longer duration of cardiopulmonary bypass (105 vs 76 min, P < 0.0001), than patients with non-VAP. No significant differences were observed between the 2 groups in terms of the types of microorganisms isolated with high proportions of Enterobacteriaceae (35%), Pseudomonas aeruginosa (20.2%) and Haemophilus spp (20.2%), except for a lower proportion of Methicillin-susceptible S. aureus in the non-VAP group (3.2% vs 7.9%, P = 0.03). In the intensive care unit, patients with non-VAP had lower sequential organ failure assessment scores than patients with VAP (8 ± 3 versus 9 ± 3, P = 0.004). On multivariate analysis, in-hospital mortality was similar in both groups (32% in the non-VAP group and 42% in the VAP group, adjusted Odds Ratio (aOR): 1.4; 95% confidence intervals (CI): 0.7-2.5; P = 0.34) and appropriate empiric antibiotic therapy was associated with a reduction of in-hospital mortality (aOR: 0.4; 95% CI: 0.2-1; P = 0.05). Piperacillin/tazobactam or imipenem monotherapy constituted appropriate empiric therapy in the two groups, with values reaching 93% and 95% with no differences between VAP and non-VAP cases. CONCLUSIONS Intensive care patients with VAP are more severely ill than non-VAP patients following CS. Nevertheless, patients with non-VAP and VAP following CS have similar outcomes. This study suggests that the empiric antibiotic regimen in patients with pneumonia following CS should include at least a broad-spectrum antibiotic targeting non-fermenting Gram-negative bacilli, regardless of the type of pneumonia, and targeting S. aureus in VAP patients.

Abstract
BACKGROUND Postoperative pulmonary complication (PPC) is a serious complication after liver surgery and is a major cause of mortality and morbidity in the intensive care unit (ICU). Therefore, the early identification of risk factors of PPCs may help to reduce the adverse outcomes. OBJECTIVE The aim of this retrospective study was to determine the predictors of PPCs in patients undergoing hepatic resection. DESIGN Retrospective, observational. METHODS The patients admitted after hepatic resection in the gastrosurgical ICU of our institute between October 2009 and June 2013 was identified. The ICU charts were retrieved from the database to identify patients who developed PPCs. A comparison of risk factors was made between the patients who developed PPC (PPC group) against the patients who did not (no-PPC group). RESULTS Of 117 patients with hepatic resection, 28 patients developed PPCs. Among these, pneumonia accounted for 12 (42.8%) followed by atelectasis in 8 (28.5%) and pleural effusion in 3 (10.7%). Among the patients developing PPCs, 16 patients were over a 70-year-old (57.1%), 21 patients were smokers (75%) and 8 patients (28.5%) had chronic obstructive pulmonary disease (COPD). The requirement for blood transfusion and duration of mechanical ventilation were greater in the patients developing PPC (2000 ± 340 vs. 1000 ± 210 ml; 10 ± 4.5 vs. 3 ± 1.3 days). CONCLUSION Old age, chronic smoking, COPD, increased blood product transfusion, increased duration of mechanical ventilation and increased length of ICU stay increased the relative risk of PPC, presence of diabetes and occurrence of surgical complications (leak, dehiscence, etc.) were independent predictive variables for the development of PPC.

Abstract
BACKGROUND Surgery for inflammatory bowel disease (IBD) is common and represents a large portion of the cost of IBD treatment. There are multiple risk factors for post-operative complications after IBD surgery, but the role of ethnicity remains unclear. The aim of our study was to compare the rate of post-operative complications in Hispanic and non-Hispanic patients with equal access to health care. METHODS We designed a case-control study including patients enrolled in a health plan available to uninsured patients at Jackson Memorial Hospital (Miami, FL, USA) who had access to health care for at least 24 consecutive months prior to surgery. Sixty-seven Hispanic patients (cases) and 75 non-Hispanic patients (controls) met criteria and were compared with respect to demographics, type of surgery, disease phenotype, and laboratory markers. Primary outcome was the development of a medical or surgical complication. RESULTS A slight numerical increase in post-operative complications was seen in Hispanic patients; this did not reach statistical significance [1.06 (95 % CI 0.48-2.36; p = 0.88)]. Factors independently associated with post-operative complications included diagnosis of ulcerative colitis [OR 5.4 (95 % CI 1.67-20.58; p = 0.004)], pre-operative albumin levels <3 mg/dL [OR: 8.2 (95 % CI 2.3-35.5; p < 0.001)], smoking [OR 15.7 (95 % CI 4.2-72.35; p < 0.001)], and use of ≥20 mg of prednisone [OR 6.7 (95 % CI 2.15-24.62; p < 0.001)]. CONCLUSIONS In a group of patients with equal access to medical care and follow-up, Hispanics and non-Hispanics with IBD that underwent surgery had no significant differences in types of IBD surgeries or post-surgical outcomes.

Abstract
Background Acceptance of healthcare-associated pneumonia (HCAP) as an entity and the associated risk of infection by potentially multidrug-resistant (MDR) organisms such as methicillin-resistant Staphylococcus aureus (MRSA), Pseudomonas and Acinetobacter have been debated. We therefore compared patients with HCAP, hospital-acquired pneumonia (HAP), and ventilator-associated pneumonia (VAP) enrolled in a trial comparing linezolid with vancomycin for treatment of pneumonia. Methods The analysis included all patients who received study drug. HCAP was defined as pneumonia occurring < 48 hours into hospitalization and acquired in a long-term care, subacute, or intermediate health care facility; following recent hospitalization; or after chronic dialysis. Results Data from 1184 patients (HCAP = 199, HAP = 379, VAP = 606) were analyzed. Compared with HAP and VAP patients, those with HCAP were older, had slightly higher severity scores, and were more likely to have comorbidities. Pseudomonas aeruginosa was the most common gram-negative organism isolated in all pneumonia classes [HCAP, 22/199 (11.1%); HAP, 28/379 (7.4%); VAP, 57/606 (9.4%); p = 0.311]. Acinetobacter spp. were also found with similar frequencies across pneumonia groups. To address potential enrollment bias toward patients with MRSA pneumonia, we grouped patients by presence or absence of MRSA and found little difference in frequencies of Pseudomonas and Acinetobacter. Conclusions In this population of pneumonia patients, the frequencies of MDR gram-negative pathogens were similar among patients with HCAP, HAP, or VAP. Our data support inclusion of HCAP within nosocomial pneumonia guidelines and the recommendation that empiric antibiotic regimens for HCAP should be similar to those for HAP and VAP.

Abstract
Combination antibiotic therapy for invasive infections with Gram-negative bacteria is employed in many health care facilities, especially for certain subgroups of patients, including those with neutropenia, those with infections caused by Pseudomonas aeruginosa, those with ventilator-associated pneumonia, and the severely ill. An argument can be made for empiric combination therapy, as we are witnessing a rise in infections caused by multidrug-resistant Gram-negative organisms. The wisdom of continued combination therapy after an organism is isolated and antimicrobial susceptibility data are known, however, is more controversial. The available evidence suggests that the greatest benefit of combination antibiotic therapy stems from the increased likelihood of choosing an effective agent during empiric therapy, rather than exploitation of in vitro synergy or the prevention of resistance during definitive treatment. In this review, we summarize the available data comparing monotherapy versus combination antimicrobial therapy for the treatment of infections with Gram-negative bacteria.

Abstract
OBJECTIVE: This double-blind, prospective, randomized, controlled trial examined the effects of thoracic epidural block and intravenous clonidine and opioid treatment on the postoperative Th1/Th2 cytokine ratio after lung surgery. The primary endpoint was the interferon γ (IFN-γ; Th1 cytokine)/interleukin 4 (IL-4; Th2 cytokine) ratio. Secondary endpoints were reductions in pain and incidence of pneumonia. METHODS: Sixty patients were randomized into three groups to receive remifentanil intravenously (remifentanil group, n = 20), remifentanil and clonidine intravenously (clonidine group, n = 20), or ropivacaine epidurally (ropivacaine group, n = 20). Pain was assessed using a numerical rating scale (NRS). Cytokines were measured using a cytometric bead array. RESULTS: Patients in the ropivacaine group (thoracic epidural block) had a significantly lower IFN-γ/IL-4 ratio at the end of surgery than those in the remifentanil group and clonidine group. There were no significant between-group differences in the IFN-γ/IL-4 ratio at other time-points. There were no differences in NRS scores at any time-point. No patient developed pneumonia. CONCLUSION: Intraoperative thoracic epidural block decreased the IFN-γ/IL-4 ratio immediately after lung surgery, indicating less inflammatory stimulation during surgery.

Abstract
BACKGROUND Although there is a wealth of guidance concerning the management of patients with ventilator-associated pneumonia (VAP), compliance with recommendations concerning optimal treatment practices is highly variable. METHODS This document presents a comprehensive care bundle package addressing all aspects of VAP diagnosis and treatment in an attempt to promote guideline-compliant practices. Uniquely, the development of these care bundles used a formalized method to assess the supporting data, based on multicriteria decision analysis. RESULTS This system allowed the numerous VAP management parameters identified from recent European guidelines to be ranked according to defined criteria. The resulting VAP care bundles are (a) diagnosis: early chest x-rays within 1 hour, immediate reporting of respiratory secretions Gram staining, and (b) therapy: immediate treatment, empiric therapy based on local pathogens and risk factors, de-escalation, assessment of response within 72 hours, and short therapy duration if feasible. CONCLUSION Adoption of these care bundles should rationalize VAP management practices and facilitate the development of consistent and guideline-compliant care processes.

Abstract
INTRODUCTION Few studies have addressed the decision-making process of antibiotic therapy (AT) in intensive care unit (ICU) patients. METHODS In a prospective observational study, all consecutive patients admitted over a one-month period (2004) to 41 French surgical (n = 22) or medical/medico-surgical ICUs (n = 19) in 29 teaching university and 12 non-teaching hospitals were screened daily for AT until ICU discharge. We assessed the modalities of initiating AT, reasons for changes and factors associated with in ICU mortality including a specific analysis of a new AT administered on suspicion of a new infection. RESULTS A total of 1,043 patients (61% of the cohort) received antibiotics during their ICU stay. Thirty percent (509) of them received new AT mostly for suspected diagnosis of pneumonia (47%), bacteremia (24%), or intra-abdominal (21%) infections. New AT was prescribed on day shifts (45%) and out-of-hours (55%), mainly by a single senior physician (78%) or by a team decision (17%). This new AT was mainly started at the time of suspicion of infection (71%) and on the results of Gram-stained direct examination (21%). Susceptibility testing was performed in 261 (51%) patients with a new AT. This new AT was judged inappropriate in 58 of these 261 (22%) patients. In ICUs with written protocols for empiric AT (n = 25), new AT prescribed before the availability of culture results (P = 0.003) and out-of-hours (P = 0.04) was more frequently observed than in ICUs without protocols but the appropriateness of AT was not different. In multivariate analysis, the predictive factors of mortality for patients with new AT were absence of protocols for empiric AT (adjusted odds ratio (OR) = 1.64, 95% confidence interval (95%CI): 1.01 to 2.69), age ≥60 (OR = 1.97, 95% CI: 1.19 to 3.26), SAPS II score >38 (OR = 2.78, 95% CI: 1.60 to 4.84), rapidly fatal underlying diseases (OR = 2.91, 95% CI: 1.52 to 5.56), SOFA score ≥6 (OR = 4.48, 95% CI: 2.46 to 8.18). CONCLUSIONS More than 60% of patients received AT during their ICU stay. Half of them received new AT, frequently initiated out-of-hours. In ICUs with written protocols, empiric AT was initiated more rapidly at the time of suspicion of infection and out-of-hours. These results encourage the establishment of local recommendations for empiric AT.

Abstract
OBJECTIVE To determine whether the acute anti-inflammatory influence of epinephrine (EPI) extends to changes in heart rate variability (HRV) induced by the prototypical inflammatory stimulus, endotoxin (lipopolysaccharide [LPS]). SUMMARY BACKGROUND DATA HRV reflects fluctuating cardiac autonomic inputs and is acutely reduced during the systemic inflammation induced by LPS as well as during severe critical illnesses such as sepsis and traumatic injury. While EPI may diminish proinflammatory cytokine release, it is unknown whether this net anti-inflammatory activity extends to HRV. METHODS Healthy volunteers (n = 17) were randomized to either saline + LPS (2 ng/kg) or LPS + antecedent EPI infusion (30 ng/kg/min) from -3 to 6 hours relative to LPS. HRV and blood samples were obtained before EPI and LPS as well as hourly afterward. Plasma cytokines were measured by ELISA. Statistical analysis was by repeated measures analysis of variance. This study was registered at Clinicaltrials.gov and is listed under the following ID number: NCT00753402. RESULTS LPS acutely influenced all measured parameters of HRV including standard deviation of the average beat to beat intervals over a 5-minute period, percentage of interval differences of successive interbeat intervals greater than 50 milliseconds and square root of the mean squared differences, high frequency (HF), low frequency, low frequency/HF, and very low frequency (all P < 0.01). EPI infusion reduced the inflammatory cytokine response to LPS as measured by decreased TNFalpha, IL-6, and IL-8 (P < 0.01). Relative to the saline + LPS group, antecedent EPI infusion was associated with further reductions in parameters of HRV measuring vagal/parasympathetic activity including, percentage of interval differences of successive interbeat intervals greater than 50 milliseconds, square root of the mean squared differences, and HF (P < 0.05). CONCLUSION Prior EPI exposure exerts anti-inflammatory influences but also may reduce vagus nerve activity. Hence, acute EPI administration may be protective against early inflammatory challenges but diminish vagal nerve responsiveness to subsequent stimuli.

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
OBJECTIVE Pseudomonas aeruginosa is a common pathogen in hospital-acquired pneumonia. Especially trauma and postsurgical patients display a profound acute phase protein response and are susceptible to acquiring pneumonia. The objective was to study the influence of the acute phase response induced by sterile tissue injury on pulmonary host defense. DESIGN Laboratory investigation. SETTING Academic medical center. SUBJECTS Female C57Bl/6 wild-type mice, 8-10 wks old. INTERVENTIONS Mice were injected subcutaneously with either turpentine or sterile saline (control) in both hind limbs 1 day before intranasal infection with P. aeruginosa. MEASUREMENTS AND MAIN RESULTS The turpentine-induced acute phase response was associated with 100% lethality after induction of pneumonia, whereas control mice all survived the Pseudomonas infection. In addition, turpentine-injected mice demonstrated much higher bacterial loads in their lungs and an increased dissemination of the infection. The acute phase reaction attenuated lung inflammation during pneumonia, as reflected by histopathology, reduced pulmonary levels of proinflammatory cytokines, and a strongly diminished recruitment of neutrophils to the site of infection. Blood neutrophils harvested from turpentine injected mice displayed a reduced capacity to up-regulate their CD11b/CD18 expression upon stimulation with Pseudomonas ex vivo and during Pseudomonas pneumonia in vivo. Administration of a blocking anti-CD11b antibody to turpentine-injected and control mice almost completely abrogated the difference in bacterial outgrowth, whereas inhibition of the sympathetic nervous system did not affect the impaired pulmonary host defense in mice with an acute phase response. CONCLUSIONS These data suggest that a systemic acute phase response might impair host defense against P. aeruginosa pneumonia, possibly in part by inhibition of CD11b/CD18-dependent neutrophil recruitment.

Abstract
BACKGROUND Although delay in the administration of appropriate antibiotic treatment for ventilator-associated or community-acquired pneumonia is associated with increased hospital mortality, impact of appropriateness of initial antibiotic therapy on outcome of postoperative pneumonia has been poorly investigated. MATERIALS AND METHODS Of 7,275 patients who had undergone intraabdominal surgery under general anesthesia between January 1998 and December 2005, we compiled a list of 101 patients with microbiologically confirmed postoperative pneumonia. We analyzed the influence of the appropriateness of initial antibiotic therapy on outcome of postoperative pneumonia using logistic regression analysis. RESULTS Among the patients with postoperative pneumonia, about a half received inadequate initial antimicrobial therapy. As well as the presence of concomitant intraabdominal abscess [odds ratio (OR) = 28.83), prolonged duration of anesthesia at surgery (OR = 22.41), and the isolation of methicillin-resistant Staphylococcus aureus (OR = 8.86), inadequate initial antibiotic therapy was a determinant of death from postoperative pneumonia (OR = 16.75). CONCLUSION The outcomes of patients with postoperative pneumonia could be improved by avoiding concomitant intraabdominal abscess, reducing surgical insult, and administering appropriate antimicrobial agents.

Abstract
Patients who undergo maxillofacial tumor surgery and reconstruction present many perioperative management challenges. This patient population commonly presents with significant medical comorbidities in addition to the site-specific challenges of these tumors and the complexity of the reconstructive surgeries. This article combines a review of the relevant literature and the experience of a busy regional maxillofacial tumor and reconstruction referral center to provide a concise reference for management of patients. In addition to the valuable system-specific information presented, the article outlines a daily clinical pathway, which is easily adapted to any clinical practice performing complex maxillofacial surgery.

Abstract
OBJECTIVE To evaluate the efficacy and safety of inhaled tobramycin (TOBI) in the treatment of ventilator-associated pneumonia (VAP) in a randomized, double-blind pilot study. PATIENTS AND METHODS Ten patients from a cohort of 108 mechanically ventilated patients with documented clinical and bacteriological evidence of VAP caused by Pseudomonas aeruginosa or Acinetobacter spp. in the surgical and trauma intensive care units of a university teaching hospital were randomized to receive either TOBI (n = 5) or intravenous tobramycin (TOBRA; n = 5). The two groups were similar in their Acute Physiology and Chronic Health Evaluation (APACHE) score, Clinical Pulmonary Infection Score (CPIS), and Multiple Organ Dysfunction Score (MODS) prior to randomization. The primary outcome measure was resolution of pneumonia. The CPIS and MODS were used as objective indicators of clinical progress. RESULTS All TOBI patients had clinical resolution of VAP. Two TOBRA patients were considered failures. One had deterioration in MODS, and the other had doubling of his serum creatinine concentration. The patients treated with TOBI may have had more ventilator-free days than those receiving TOBRA, but the difference was not statistically significant owing to the small sample size (24 +/- 3 vs. 14 +/- 13 days; p = 0.12). CONCLUSION Aerosolized tobramycin for the treatment of VAP appeared safe and effective in this pilot study. A larger study is warranted to determine if aerosolized tobramycin will lead to better outcomes than intravenous tobramycin when used for the treatment of VAP.

Abstract
OBJECTIVE Staphylococcus aureus is the most common cause of healthcare-associated infections. Intranasal mupirocin treatment probably decreases S. aureus infections among colonized surgical patients. Using cost-effectiveness analysis, we evaluated the cost-effectiveness of preoperative use of mupirocin for the prevention of healthcare-associated S. aureus infections. METHODS Three strategies were compared: (1) screen with nasal culture and give treatment to carriers, (2) give treatment to all patients without screening, and (3) neither screen nor treat. A societal perspective was taken. Adverse outcomes included bloodstream infection, pneumonia, surgical site infection, death due to underlying illness or infection, readmission, and the need for home health care. Data inputs were obtained from an extensive MEDLINE review and from publicly available government data sources. The following base-case data inputs (and ranges) for sensitivity analysis were used: rate of S. aureus carriage, 23.1% (19%-55%); efficacy of mupirocin treatment, 51% (8%-75%); mupirocin treatment cost, 48.36 US Dollars (24.18-57.74 US Dollars); and hospital costs of bloodstream infection, 25,128 US Dollars (6,194-40,211 US Dollars), pneumonia, 18,366 US Dollars (5,574-28,952 US Dollars), and surgical site infection 16,256 US Dollars (5,119-22,553 US Dollars). Widespread use of mupirocin has been associated with high levels of mupirocin resistance; therefore, a broad range of estimates for efficacy was tested in the sensitivity analysis. PATIENTS The target population included patients undergoing nonemergent surgery requiring postoperative hospitalization. RESULTS Both the screen-and-treat and treat-all strategies were cost saving, saving 102 US Dollars per patient screened and 88 US Dollars per patient treated, respectively. In 1-way sensitivity analyses, the model was robust with respect to all data inputs except for the efficacy of mupirocin treatment. If the efficacy is less than 16.1%, then the screen-and-treat strategy is cost incurring. A treat-all strategy was more cost saving if the rate of S. aureus carriage was greater than 42.7%, the mupirocin cost was less than 29.87 US Dollars, or nursing compensation was greater than 64.21 US Dollars per hour. CONCLUSION Administration of mupirocin before surgery is cost saving, primarily because healthcare-associated infections are very expensive. The level of mupirocin efficacy is critical to the cost-effectiveness of this intervention.

Abstract
OBJECTIVE To measure the clinical and economic impact of postoperative hospital-acquired pneumonia (HAP) and to identify risk factors for the development of HAP. SUMMARY BACKGROUND DATA Although postoperative HAP is recognized to be an major risk associated with surgery, little is known about the overall outcomes of patients whose hospital stay is complicated by HAP following surgery. METHODS We studied 618,495 patients who underwent an intra-abdominal operation from the National Inpatient Sample database over a 1-year period (January 2000 to December 2000) using CPT codes and discharge diagnoses identified by the Clinical Classification Software. Data collected included demographic characteristics, type of operation, in-hospital mortality, discharge disposition, length of stay, and hospital charges. RESULTS Of the 13,292 patients with HAP following intra-abdominal surgery, 1421 died prior to discharge (mortality = 10.7%) compared with 7217 deaths in the control group of patients without HAP following intra-abdominal surgery (mortality = 1.2%) (P < 0.001). HAP was independently associated with a 4.13-fold (95% confidence interval = 3.94-4.34) increase in risk to be discharged to a skilled nursing facility. The mean length of hospital stay for intra-abdominal patients who developed HAP was significantly greater compared with intra-abdominal surgery patients who did not develop HAP (17.10 days versus 6.07 days, P < 0.001). After adjusting for patient characteristics, HAP was independently associated with a 75% (28,160.95 dollars; 95% confidence interval, 27,543.76 dollars - 28,778.13 dollars) mean increase in total hospital charges. CONCLUSIONS Given the high incidence and significant impact of HAP on patient outcomes, early preventive strategies and interventions to reduce HAP should be a priority.

Abstract
Ventilator-associated pneumonia occurs in the evolution of 8 to 70% of patients in the Intensive Care Unit. It is the main site of nosocomial infection for mechanically ventilated patients. Nosocomial pneumonia represents an important cause of morbidity and mortality, despite progresses in antibiotic prescription, use of intensive care and prevention. This review is based on the ATS guidelines, and reviews epidemiology, diagnosis and treatment of ventilator-acquired pneumonia, in non-immunocompromised adults.
