Purpose: Severe community-acquired pneumonia (CAP) requiring intensive care unit admission is associated with significant acute and long-term morbidity and mortality. We hypothesized that downregulation of systemic and pulmonary inflammation with prolonged low-dose methylprednisolone treatment would accelerate pneumonia resolution and improve clinical outcomes.

Methods: This double-blind, randomized, placebo-controlled clinical trial recruited adult patients within 72-96 h of hospital presentation.

Competency in interprofessional quality improvement and performance measurement is required by the Accreditation Council for Graduate Medical Education. We implemented an interprofessional quality improvement project to support trainee involvement in systems-level improvement to reduce hospital length of stay and engage trainees in efforts to improve the validity and reliability of clinical documentation contributing to risk-adjusted performance measures. The intervention had three components: daily interprofessional disposition huddles to discuss discharge needs, medical documentation curriculum to improve clinical data accuracy, and scheduled coding huddles to provide real-time feedback on documentation.

It is unclear whether concurrent pneumonia and chronic obstructive pulmonary disease (COPD) have a higher mortality than either condition alone. Further, it is unknown how this interaction changes over time. We explored the effect of pneumonia and COPD on inpatient, 30-day and overall mortality.

Rationale: The use of sedation allows medical procedures to be performed outside the operating room while ensuring patient comfort and a controlled environment to increase the yield of the procedure. There is concern about a higher risk of adverse events with use of sedation in patients with obstructive sleep apnea.

Objectives: We aimed to determine if the presence of obstructive sleep apnea increased the risk of hospitalization and/or health care use after patients received moderate conscious sedation for an elective, ambulatory colonoscopy.

Importance: As quality measures increasingly become tied to payment, evaluating the most effective ways to provide high-quality care becomes more important.

Objectives: To determine whether mandated reporting for ventilator and catheter bundle compliance is correlated with decreased infection rates, and to determine whether labor-intensive audits are correlated with compliance.

Design, Setting, And Participants: Multiyear retrospective review of aggregated data from all patients admitted to 15 intensive care units in a Veterans Affairs hospital setting (the Veterans Integrated Service Network 16) from 2009 to 2011.

Intra-abdominal hypertension/abdominal compartment syndrome (IAH/ACS) is a well-recognized entity among surgical subspecialties. Nevertheless, it has been proven to be present in the medical critically ill population. Prospective and retrospective observational studies have found medical patients with IAH/ACS to be associated with death in the intensive care unit and other poor outcomes.

Importance: Recently, preoperative lung cancer staging has evolved to include endobronchial ultrasonography-guided transbronchial needle aspiration (EBUS-TBNA) biopsies of the hilar and mediastinal lymph nodes, but the feasibility and usefulness of the procedure have not been well studied in the veteran population.

Objective: To determine the safety and effectiveness of EBUS-TBNA as a key component of a preoperative staging algorithm for lung cancer in veterans.

Design, Setting, And Participants: Review of a prospectively maintained thoracic surgery database that includes patients who underwent lung resection for lung cancer between January 1, 2009, and December 31, 2012, at a single Veterans Affairs medical center among a consecutive cohort of 166 patients with clinically early-stage (I or II) lung cancer who underwent lobectomy with nodal dissection.

Background And Objective: Microdebrider bronchoscopy is a relatively new modality for the management of central airway obstruction (CAO) of both benign and malignant origin. Our objective was to describe our experience with this technique, with special attention to its safety and effectiveness.

Methods: We retrospectively reviewed cases of therapeutic bronchoscopies using microdebrider for CAO from two institutions (M.

Obstructive airway diseases including asthma, chronic obstructive pulmonary disease and cystic fibrosis present with dyspnea and variety of other symptoms. Physiologically, they are characterized by maximal expiratory flow limitation and pathologically, by inflammation of the airways and the lung parenchyma. Inflammation plays a major role in the gradual worsening of the lung function resulting in worsening symptoms.
