The article focuses on a case of a 66-year-old man with underlying chronic obstructive pulmonary disease (COPD) who presents with symptoms of community-acquired pneumonia. It authors provide evidence-based strategies for evaluation and treatment, followed by a review of clinical guidelines when applicable.

In an effort to decrease antimicrobial resistance and inappropriate antibiotic use, The Joint Commission (TJC) recently issued new antimicrobial stewardship standards, consisting of 8 elements of performance, applicable to hospitals effective January 1, 2017. These standards coincide with those recommended by the Infectious Diseases Society of America (IDSA) and the Society of Healthcare Epidemiology (SHEA) guidelines. Little guidance exists on the "how" from these guidance documents. We review the 8 standards and provide real-world experience from established antimicrobial stewardship programs (ASPs) on how institutions can comply with these guidelines to reduce inappropriate antibiotic usage, decrease antimicrobial resistance, and optimize patient outcomes. TJC antimicrobial stewardship standards demonstrate actions being taken at the national level to make quality and patient safety a priority. [ABSTRACT FROM AUTHOR]

Background. Solithromycin, a novel macrolide antibiotic with both intravenous and oral formulations dosed once daily, has completed 2 global phase 3 trials for treatment of community-acquired bacterial pneumonia. Methods. A total of 863 adults with community-acquired bacterial pneumonia (Pneumonia Outcomes Research Team [PORT] class II-IV) were randomized 1:1 to receive either intravenous-to-oral solithromycin or moxifloxacin for 7 once-daily doses. All patients received 400 mg intravenously on day 1 and were permitted to switch to oral dosing when clinically indicated. The primary objective was to demonstrate noninferiority (10% margin) of solithromycin to moxifloxacin in achievement of early clinical response (ECR) assessed 3 days after first dose in the intent-to-treat (ITT) population. Secondary endpoints included demonstrating noninferiority in ECR in the microbiological ITT population (micro-ITT) and determination of investigator-assessed success rates at the short-term follow-up (SFU) visit 5-10 days posttherapy. Results. In the ITT population, 79.3% of solithromycin patients and 79.7% of moxifloxacin patients achieved ECR (treatment difference, -0.46; 95% confidence interval [CI], -6.1 to 5.2). In the micro-ITT population, 80.3% of solithromycin patients and 79.1% of moxifloxacin patients achieved ECR (treatment difference, 1.26; 95% CI, -8.1 to 10.6). In the ITT population, 84.6% of solithromycin patients and 88.6% of moxifloxacin patients achieved clinical success at SFU based on investigator assessment. Mostly mild/moderate infusion events led to higher incidence of adverse events overall in the solithromycin group. Other adverse events were comparable between treatment groups. Conclusions. Intravenous-to-oral solithromycin was noninferior to intravenous-to-oral moxifloxacin. Solithromycin has potential to provide an intravenous and oral option for monotherapy for community-acquired bacterial pneumonia. [ABSTRACT FROM AUTHOR]

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 FROM AUTHOR]

Antimicrobial stewardship programs (ASPs) are a key national initiative to promote appropriate use of antibiotics and to reduce the burden of resistance. The dilemma of managing the outlier physician is especially complex. We outline strategies to establish a successful ASP that reviews appropriate efforts to achieve the goal of modifying outlier physicians' behavior. One must try to differentiate deviation from ASP norms from all other issues of outliers. Essential elements include identifying and understanding the local problems, planning, and achieving hospital administration and medical staff support. A successful ASP includes effective communication and acceptance of evidence-based recommendations, so that patient clinical outcomes will be optimized. [ABSTRACT FROM AUTHOR]

Importance: The National Action Plan for Combating Antibiotic-Resistant Bacteria set a goal of reducing inappropriate outpatient antibiotic use by 50% by 2020, but the extent of inappropriate outpatient antibiotic use is unknown.Objective: To estimate the rates of outpatient oral antibiotic prescribing by age and diagnosis, and the estimated portions of antibiotic use that may be inappropriate in adults and children in the United States.Design, Setting, and Participants: Using the 2010-2011 National Ambulatory Medical Care Survey and National Hospital Ambulatory Medical Care Survey, annual numbers and population-adjusted rates with 95% confidence intervals of ambulatory visits with oral antibiotic prescriptions by age, region, and diagnosis in the United States were estimated.Exposures: Ambulatory care visits.Main Outcomes and Measures: Based on national guidelines and regional variation in prescribing, diagnosis-specific prevalence and rates of total and appropriate antibiotic prescriptions were determined. These rates were combined to calculate an estimate of the appropriate annual rate of antibiotic prescriptions per 1000 population.Results: Of the 184,032 sampled visits, 12.6% of visits (95% CI, 12.0%-13.3%) resulted in antibiotic prescriptions. Sinusitis was the single diagnosis associated with the most antibiotic prescriptions per 1000 population (56 antibiotic prescriptions [95% CI, 48-64]), followed by suppurative otitis media (47 antibiotic prescriptions [95% CI, 41-54]), and pharyngitis (43 antibiotic prescriptions [95% CI, 38-49]). Collectively, acute respiratory conditions per 1000 population led to 221 antibiotic prescriptions (95% CI, 198-245) annually, but only 111 antibiotic prescriptions were estimated to be appropriate for these conditions. Per 1000 population, among all conditions and ages combined in 2010-2011, an estimated 506 antibiotic prescriptions (95% CI, 458-554) were written annually, and, of these, 353 antibiotic prescriptions were estimated to be appropriate antibiotic prescriptions.Conclusions and Relevance: In the United States in 2010-2011, there was an estimated annual antibiotic prescription rate per 1000 population of 506, but only an estimated 353 antibiotic prescriptions were likely appropriate, supporting the need for establishing a goal for outpatient antibiotic stewardship.
