Infectious diseases and impaired renal function often occur in critically ill patients, and delaying the start of appropriate empiric antimicrobial therapy or starting inappropriate therapy has been associated with poor outcomes. Our primary objective was to critically review and discuss the influence of chronic kidney disease (CKD) and acute kidney injury(More)
Enterococci are a common cause of urinary tract infections (UTIs) among hospitalized patients. The rising prevalence of vancomycin-resistant enterococci (VRE) is of particular concern within many institutions because of its association with increased mortality and health care costs, as well as limited treatment options. Clinicians need to differentiate(More)
BACKGROUND Vancomycin-resistant enterococci (VRE) are a common cause of nosocomial urinary tract infections (UTIs) among hospitalized patients. Clinicians need to differentiate between VRE-associated urinary colonization, asymptomatic bacteriuria, and UTIs to determine the need for treatment and length of therapy. OBJECTIVE To characterize the diagnosis(More)
BACKGROUND Outpatient parenteral antimicrobial therapy (OPAT) is frequently prescribed at hospital discharge, often without infectious diseases (ID) clinician oversight. We developed a multidisciplinary team, including an ID pharmacist, to review OPAT care plans at hospital discharge to improve safety, clinical efficacy, practicality, and appropriateness of(More)
PURPOSE Vancomycin dosing and monitoring algorithms for patients with end-stage renal disease (ESRD) receiving intermittent hemodialysis are reviewed. SUMMARY Vancomycin is one of the most commonly administered antimicrobial agents in adult patients with ESRD receiving intermittent hemodialysis. However, despite the availability of many published studies,(More)
OBJECTIVE The objective of this study was to evaluate clinical outcomes and risk factors associated with clinical failure in patients hospitalized with cellulitis with or without abscess. METHODS We performed a retrospective cohort study among adults admitted for cellulitis/cutaneous abscess from July 1, 2009 through June 30, 2010. Binary univariate and(More)
PURPOSE Published evidence regarding the influence of cirrhosis on the clinical pharmacokinetics of antibacterial agents is reviewed; dosing recommendations and a decision algorithm are provided. SUMMARY A systematic PubMed search (1960-2013) was conducted to identify literature pertaining to the use of antibacterials with hepatobiliary clearance in adult(More)
Atrial fibrillation (AF) is the most common cardiac dysrhythmia. Its prevalence, risk factors, course, and complications are not well described in critically ill trauma patients. This was a retrospective, single-center, cohort study at an academic, level 1 trauma center. Trauma patients >18 years, identified from the trauma registry and admitted to the(More)
BACKGROUND A resurgence of aminoglycoside use has followed the recent increase of multidrug-resistant gram-negative pathogens and is often needed even in the treatment of dialysis-dependent patients; however, studies evaluating the treatment of gram-negative infections with aminoglycosides, including the optimal dose, in the setting of dialysis are limited.(More)
We investigated the frequency and determinants of guideline-discordant antibiotic prescribing in outpatients with respiratory infections or cystitis. Antibiotic prescribing was guideline discordant in 60% of patients. The most common reason for discordance was prescribing an antibiotic when not indicated. In a multivariate analysis, physicians in training(More)
