Low-dose methylprednisolone treatment in critically ill patients with severe community-acquired pneumonia.

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. Patients were randomized in 1:1 ratio; an intravenous 40 mg loading bolus was followed by 40 mg/day through day 7 and progressive tapering during the 20-day treatment course. Randomization was stratified by site and need for mechanical ventilation (MV) at the time of randomization. Outcomes included a primary endpoint of 60-day all-cause mortality and secondary endpoints of morbidity and mortality up to 1 year of follow-up. RESULTS: Between January 2012 and April 2016, 586 patients from 42 Veterans Affairs Medical Centers were randomized, short of the 1420 target sample size because of low recruitment. 584 patients were included in the analysis. There was no significant difference in 60-day mortality between the methylprednisolone and placebo arms (16% vs. 18%; adjusted odds ratio 0.90, 95% CI 0.57-1.40). There were no significant differences in secondary outcomes or complications. CONCLUSIONS: In patients with severe CAP, prolonged low-dose methylprednisolone treatment did not significantly reduce 60-day mortality. Treatment was not associated with increased complications.

Telehealth Pulmonary Rehabilitation for Patients With Severe Chronic Obstructive Pulmonary Disease.

For patients with chronic obstructive pulmonary disease, a home-based, interactive telehealth program can improve accessibility to pulmonary rehabilitation and reduce travel costs.

Impact of a Resident-Centered Interprofessional Quality Improvement Intervention on Acute Care Length of Stay.

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. Outcome measures included an unadjusted and risk-adjusted measure of hospital length of stay. Case severity index (CSI) served as a process measure. Statistical process control charts were used to measure change over time. The mean unadjusted length of stay decreased from 5.84 to 4.98 days. Both the unadjusted and the risk-adjusted length of stay measures exceeded the lower control limit of the statistical control chart. The CSI increased and exceeded the upper control limit of the statistical control chart. Improvements were sustained in the year following implementation. The intervention offers a model for academic institutions to satisfy new Common Program Requirements by engaging trainees in performance measurement and interprofessional improvement efforts.

Mortality in Patients Admitted for Concurrent COPD Exacerbation and Pneumonia.

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. We used a Veterans Health Affairs database to compare patients who were hospitalized for a COPD exacerbation without pneumonia (AECOPD), patients hospitalized for pneumonia without COPD (PNA) and patients hospitalized for pneumonia who had a concurrent diagnosis of COPD (PCOPD). We studied records of 15,065 patients with the following primary discharge diagnoses: (a) AECOPD cohort (7,154 individuals); (b) PNA cohort (4,433 individuals); and (c) PCOPD (3,478 individuals), comparing inpatient, 30-day and overall mortality in the three study cohorts. We observed a stepwise increase in inpatient mortality for AECOPD, PNA and PCOPD (4.8%, 9.5% and 13.2%, respectively). These differences persisted at 30 days post-discharge (AECOPD = 6.7%, PNA = 12.4% and PCOPD = 14.6%; p < 0.0001), but not throughout the study period (median follow-up: 37 months). With time, the death rate rose disproportionally in patients who had been admitted for AECOPD (AECOPD = 64.5%; PNA = 57.4% and PCOPD 66.2%; p < 0.001). In multivariate analysis, PCOPD predicted the greatest inpatient mortality (p < 0.001). The data showed a progression in inpatient and 30-day mortality from AECOPD to PNA to PCOPD. Pneumonia and COPD differentially affected inpatient, 30-day and overall mortality with pneumonia affecting predominantly inpatient and 30-day mortality while COPD affecting the overall mortality.

Obstructive Sleep Apnea Is Not Associated with Higher Health Care Use after Colonoscopy under Conscious Sedation.

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. METHODS: We conducted a retrospective case-control database and chart review study. We compared hospital admissions, intensive care unit (ICU) admissions, and emergency room visits at 24 hours, 7 days, and 30 days in patients with obstructive sleep apnea (n = 3,860) and without obstructive sleep apnea (n = 2,374) who had undergone an elective, ambulatory colonoscopy with sedation. MEASUREMENTS AND MAIN RESULTS: We found no significant differences in hospital admissions, ICU admissions, or emergency room visits between the two groups at any time point within the 30 days following the procedures. In a sensitivity analysis in which we compared 827 individuals with polysomnographically confirmed sleep apnea with control subjects, there was still no difference in hospital admissions, ICU admissions, or emergency room visits in the 30 days after receiving sedation for the procedure. Outcomes were not different in individuals with various severities of obstructive sleep apnea. CONCLUSIONS: The presence of obstructive sleep apnea was not associated with increased early hospital admissions, ICU admissions, or emergency room visits after colonoscopy with sedation.

Mandated self-reporting of ventilator-associated pneumonia bundle and catheter-related bloodstream infection bundle compliance and infection rates.

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. EXPOSURES: Ventilator-associated pneumonia and catheter-related bloodstream infections. MAIN OUTCOMES AND MEASURES: Mean rates of ventilator-associated pneumonia and catheter-related bloodstream infection were analyzed by year. Relationships between infection rates, self-reported compliance, and audits were analyzed by Pearson correlation. RESULTS: During the study period, ventilator-associated pneumonia decreased from 2.50 to 1.60 infections per 1000 ventilator days (P = .07). The rate of pneumonia was not correlated with self-reported compliance overall (R = 0.19) or by individual year (2009, R = 0.30; 2010, R = 0.24; 2011, R = 0.46); there was a correlation in cardiac intensive care units (R = -0.70) but not other types of intensive care units (mixed, R = -0.18; medical, R = 0.42; surgical, R = 0.34). Catheter-related bloodstream infections decreased from 2.38 to 0.73 infections per 1000 catheter days (P = .04). The rate of catheter infection was not correlated with self-reported compliance overall (R = -0.18), by individual year (2009, R = -0.39; 2010, R = -0.42; 2011, R = 0.37), or by intensive care unit type (mixed, R = -0.19; cardiac, R = 0.55; medical, R = 0.17; surgical, R = -0.44). CONCLUSIONS AND RELEVANCE: Current mandated self-reported compliance and audit measures are poorly correlated with decreased ventilator-associated pneumonia or catheter-related bloodstream infection.

Intra-abdominal hypertension in medical critically ill patients: a narrative review.

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. Frequently, it is underdiagnosed and undertreated in this patient group. Limitations encountered in these observational studies are their small population size and single-center design. In addition, most studies target consecutive intensive care unit admissions instead of limiting IAH/ACS screening to a predefined population confined by their risk factors (unspecified ascites, mechanical ventilation, positive fluid balance, etc.). Generally, medical patients with IAH/ACS are more severely ill compared with surgical patients. Furthermore, they are less likely to receive treatment targeted at lowering intra-abdominal pressure. Medical treatment of IAH/ACS has not been demonstrated to be specifically effective to avoid decompressive surgery. Identifying medical patients at risk of IAH represents an underresearched area for which training in measurement of abdominal pressure surrogates, awareness of its prevalence, and prevention and treatment of such condition could further improve outcomes in critically ill medical patients.

Endobronchial ultrasonography-guided transbronchial needle aspiration biopsy for preoperative nodal staging of lung cancer in a veteran population.

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. INTERVENTIONS: Endobronchial ultrasonography-guided transbronchial needle aspiration mediastinal staging (EBUS group) in 62 patients (37.3%) was compared with noninvasive nodal staging plus integrated positron emission tomography-computed tomography only (PET/CT-only group) in 104 patients (62.7%). The accuracy of nodal staging was assessed by comparison with the final pathological staging after complete nodal dissection (the gold standard). MAIN OUTCOMES AND MEASURES: Primary outcomes were feasibility, safety, accuracy, and negative predictive value of EBUS-TBNA for preoperative nodal staging. A secondary outcome was the rate of nontherapeutic lung resection for occult N2 disease, with comparison between the EBUS group and the PET/CT-only group. RESULTS: No significant complications were attributable to the EBUS-TBNA procedure. In the EBUS group, 258 lymph node stations were sampled. N1 hilar metastases were diagnosed in 8 patients (12.9%) before surgery, and the remainder were staged N0. Accuracy and negative predictive value of EBUS-TBNA were 93.5% (58 of 62) and 92.6% (50 of 54), respectively. The overall rate of nontherapeutic lung resection performed in patients with occult N2 disease was 10.8% (18 of 166) (8.1% in the EBUS group and 12.5% in the PET/CT-only group) (P = .37). CONCLUSION AND RELEVANCE: A preoperative lung cancer staging strategy that includes EBUS-TBNA seems to be safe and effective in a veteran population, resulting in a low rate of nontherapeutic operations because of occult N2 nodal disease.

Safety and effectiveness of microdebrider bronchoscopy for the management of central airway obstruction.

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.D. Anderson Cancer Center and Michael E. Debakey VA Medical Center, Houston) from August 2008 through February 2012. RESULTS: We identified 51 cases. Malignant CAO was detected in 36 cases (71%): non-small-cell lung cancer (n = 22), melanoma (n = 3), small-cell-lung cancer (n = 2), thyroid cancer (n = 2), esophageal carcinoma (n = 2), breast cancer (n = 2), and others (n = 3). Benign diseases included: papillomas (n = 8), granulation tissue (n = 3), and others (n = 4). Obstruction was purely endoluminal in 32 cases (63%). Pre-treatment obstruction was severe in 25 cases (49%), moderate in 20 cases (39%) and mild in 6 (12%). Lesions were located in the trachea (n = 23), main stem bronchi (n = 25), and bronchus intermedius (n = 8), with some patients having more than one lesion. After tumor debulking with microdebrider, the residual airway obstruction was insignificant (n = 27 cases; 53%), mild (n = 23 cases; 45%), and moderate (n = 1; 2%). No major complications were encountered, only 2 patients had mild adverse events: one case of pneumomediastinum, and one self-expandable stent damage requiring its removal. Two patients (4%) died within 30 days of causes unrelated to the procedure or the CAO. CONCLUSIONS: Microdebrider bronchoscopy is a potentially safe and effective way to manage central airway obstruction of both malignant and benign origin.

The potential role of natural agents in treatment of airway inflammation.

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. For many years, scientists focused their efforts in identifying various pathways involved in the chronic inflammation present in these diseases. Further, studies are underway to identify various molecular targets in these pathways for the purpose of developing novel therapeutic agents. Natural agents have been used for thousands of years in various cultures for the treatment of several medical conditions and have mostly proven to be safe. Recent in vivo and in vitro studies show potential anti-inflammatory role for some of the existing natural agents. This review provides an overview of the literature related to the anti-inflammatory effects of some of the natural agents which have potential value in the treatment of inflammatory lung diseases.
