Abstract
Introduction Chronic obstructive pulmonary disease (COPD) is the third-leading cause of death globally and is responsible for over 3 million deaths annually. One of the factors contributing to the significant healthcare burden for these patients is readmission. The aim of this review is to describe significant predictors and prediction scores for all-cause and COPD-related readmission among patients with COPD. Methods A search was conducted in Ovid MEDLINE, Ovid Embase, Cochrane Database of Systematic Reviews, and Cochrane Central Register of Controlled Trials, from database inception to June 7, 2022. Studies were included if they reported on patients at least 40 years old with COPD, readmission data within 1 year, and predictors of readmission. Study quality was assessed. Significant predictors of readmission and the degree of significance, as noted by the p-value, were extracted for each study. This review was registered on PROSPERO (CRD42022337035). Results In total, 242 articles reporting on 16,471,096 patients were included. There was a low risk of bias across the literature. Of these, 153 studies were observational, reporting on predictors; 57 studies were observational studies reporting on interventions; and 32 were randomized controlled trials of interventions. Sixty-four significant predictors for all-cause readmission and 23 for COPD-related readmission were reported across the literature. Significant predictors included 1) pre-admission patient characteristics, such as male sex, prior hospitalization, poor performance status, number and type of comorbidities, and use of long-term oxygen; 2) hospitalization details, such as length of stay, use of corticosteroids, and use of ventilatory support; 3) results of investigations, including anemia, lower FEV1, and higher eosinophil count; and 4) discharge characteristics, including use of home oxygen and discharge to long-term care or a skilled nursing facility. Conclusion The findings from this review may enable better predictive modeling and can be used by clinicians to better inform their clinical gestalt of readmission risk.

Azithromycin Versus Beta-lactams in Hospitalized Patients with Acute Exacerbations of COPD. J Gen Intern Med 2022; 37:4183-4188. [PMID: 35316516 PMCID: PMC8939242 DOI: 10.1007/s11606-022-07486-5] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/25/2021] [Accepted: 03/04/2022] [Indexed: 01/04/2023]
Abstract
BACKGROUND There is a lack of data comparing azithromycin to alternative antibiotic choices in managing COPD exacerbations, making appropriate antibiotic selection controversial. OBJECTIVE To compare treatment failure in hospitalized patients with acute exacerbations of chronic obstructive pulmonary disease (AECOPD) receiving azithromycin or beta-lactams. DESIGN Retrospective, multicenter cohort study using logistic regression for multivariable analysis. Patients were included if they were at least 18 years old, admitted with AECOPD, and received at least two consecutive days of either a beta-lactam or azithromycin. Patients were excluded if they received concomitant azithromycin and beta-lactam antibiotics during the first 2 days, had a history of other severe underlying pulmonary diseases, pregnancy, COVID-19, alpha-1 antitrypsin deficiency, or received a corticosteroid for a diagnosis other than COPD. PARTICIPANTS Five hundred ninety-five patients were included, of which 428 (72%) received azithromycin and 167 patients (28%) received a beta-lactam. MAIN MEASURES The primary endpoint was treatment failure rate in patients receiving azithromycin versus beta-lactams, which was a composite endpoint defined as in-hospital mortality, admission to intensive care, initiation of invasive mechanical ventilation, initiation of a new antibiotic, steroid therapy escalation, or readmission due to AECOPD within 30 days. KEY RESULTS The composite primary outcome occurred in 84 patients (19.6%) in the azithromycin group and 54 (32.3%) in the beta-lactam group (p<0.01). The difference in the composite outcome was a result of higher rates of new antibiotics during admission (12.6% vs 4.2%; p<0.01) and higher readmission within 30 days (19.3% vs 12.4%; p=0.032). After controlling for potential confounders, beta-lactams continued to demonstrate a higher risk for treatment failure (OR, 2.30; 95% CI, 1.46-3.63). There was no difference in adverse effects between the groups. CONCLUSION Azithromycin was associated with less treatment failure in AECOPD which was driven by lower readmission rates and prescription of new antimicrobials.

Abstract
Azithromycin was thought to prevent acute exacerbations of chronic obstructive pulmonary disease (AECOPDs) by anti-microbial and anti-inflammatory effects. However, it's value in the treatment of critically ill patients with AECOPD before ICU admission remains unclear. Our study aimed to find whether azithromycin use prior to ICU admission leads to better clinical outcomes for those individuals. 533 critically ill patients with AECOPD from the MIMIC-IV database were included. Univariate followed multivariate logistic regression was used to select risk factors for short-term mortality. The multivariable logistic regression models were implemented to investigate the association between azithromycin use before ICU admission and short-term mortality. Lower short-term mortality was observed in the azithromycin group (p = .021), independent of differences in demographic data and other clinical outcomes (p>.05). Azithromycin use before ICU admission was proved to have a decreased short-term mortality by multivariable logistic regression (p<.05). The results remained consistent after being stratified by age, SOFA scores, pH, and cancer diagnosis. Azithromycin use prior to ICU admission was associated with lower short-term mortality for critically ill AECOPD patients.

Abstract
Objective This study aimed to assess whether the short-term use of macrolide antibiotics during hospitalization can reduce in-hospital all-cause mortality compared to non-macrolide treatment in patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD). Methods A propensity score (PS) matching analysis was performed using retrospective data from the admission records of AECOPD patients in the medical general ward and medical intensive care unit of a tertiary care center between October 2015 and September 2018. The multivariable Cox proportional hazard model was performed to eliminate residual confounding after the PS analysis. Results The mortality rate was 11.1% of 1528 admissions in the PS matching cohort. Approximately 70% of patients had respiratory failure requiring intubation on initial admission, and 34% had pneumonia. Macrolide treatment significantly reduced in-hospital mortality among AECOPD patients (adjusted hazard ratio, 0.55; 95% confidence interval 0.32–0.96; P=0.034). Clarithromycin was the most commonly prescribed macrolide (80%). Conclusion Macrolide antibiotics reduced in-hospital mortality in hospitalized AECOPD patients. The combination of antimicrobial and immunomodulatory effects of macrolide treatment could play an essential role.

Short- Versus Standard-Course Nonmacrolide Antibiotic Treatment in Acute Exacerbations of Chronic Obstructive Pulmonary Disease: A Retrospective, Observational Cohort Study. Clin Ther 2021; 43:1948-1956.e1. [PMID: 34736767 DOI: 10.1016/j.clinthera.2021.09.015] [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: 08/02/2021] [Revised: 09/13/2021] [Accepted: 09/20/2021] [Indexed: 11/24/2022]
Abstract
PURPOSE In critically ill patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD) and without positive microbiological data, the efficacy and tolerability of short-course nonmacrolide antibiotics are ill-described and have pertinent implications in antimicrobial stewardship. This study compared the efficacy and tolerability of nonmacrolide antibiotic strategies in critically ill patients with AECOPD and without pertinent positive microbiological testing. METHODS This single-center, retrospective cohort study was conducted in culture-negative critically ill adults admitted to an intensive care unit (ICU) between July 1, 2014, and July 1, 2019, for the treatment of AECOPD. Included patients received treatment with an empiric corticosteroid, azithromycin, and/or a nonmacrolide antibiotic. Patients treated with a nonmacrolide antibiotic for ≤3 and >3 days made up the short- and standard-course groups, respectively. The prevalence of in-hospital mortality, progression to the need for ventilation, and/or readmission for AECOPD within 30 days (primary composite end point) was compared between the two groups. Additional end points included hospital and ICU lengths of stay (LOS), all-cause 30-day readmission, and prevalence of antibiotic-related adverse events. FINDINGS A total of 135 patients were included (short course, 66; standard course, 69). The differences in the primary composite end point (short vs standard, 24.2% vs 39.1%; P = 0.06) and its individual components were not significant. The median ICU LOS (2 vs 3 days) and hospital LOS (4 vs 6 days) were shorter in the short-course group (both, P < 0.01). Multivariate logistic regression confirmed no association between group assignment and the primary end point. IMPLICATIONS Short-course nonmacrolide therapy in patients with AECOPD and no positive microbiological testing was not associated with differences in mortality, progression to ventilation, readmission rate, or prevalence of adverse drug events. Larger-scale prospective studies are needed to validate these findings.

Abstract
Chronic obstructive pulmonary disease (COPD) is an important public health problem that manifests with exacerbations and causes serious mortality and morbidity in both developed and developing countries. COPD exacerbations usually present to emergency departments, where these patients are diagnosed and treated. Therefore, the Emergency Medicine Association of Turkey and the Turkish Thoracic Society jointly wanted to implement a guideline that evaluates the management of COPD exacerbations according to the current literature and provides evidence-based recommendations. In the management of COPD exacerbations, we aim to support the decision-making process of clinicians dealing with these patients in the emergency setting.

Abstract
Patients with chronic obstructive pulmonary disease (COPD) experience high rates of hospital readmissions, placing substantial clinical and economic strain on the healthcare system. Therefore, it is essential to implement evidence-based strategies for preventing these readmissions. The primary objective of our systematic review was to identify and describe the domains of existing primary research on strategies aimed at reducing hospital readmissions among adult patients with COPD. We also aimed to identify existing gaps in the literature to facilitate future research efforts. A total of 843 studies were captured by the initial search and 96 were included in the final review (25 randomized controlled trials, 37 observational studies, and 34 non-randomized interventional studies). Of the included studies, 72% (n = 69) were considered low risk of bias. The majority of included studies (n = 76) evaluated patient-level readmission prevention strategies (medication and other treatments (n = 25), multi-modal (n = 19), follow-up (n = 16), telehealth (n = 8), education and coaching (n = 8)). Fewer assessed broader system- (n = 13) and policy-level (n = 7) strategies. We observed a trend toward reduced all-cause readmissions with the use of medication and other treatments, as well as a trend toward reduced COPD-related readmissions with the use of multi-modal and broader scale system-level interventions. Notably, much of this evidence supported shorter-term (30-day) readmission outcomes, while little evidence was available for longer-term outcomes. These findings should be interpreted with caution, as considerable between-study heterogeneity was also identified. Overall, this review identified several evidence-based interventions for reducing readmissions among patients with COPD that should be targeted for future research.Supplemental data for this article is available online at https://doi.org/10.1080/15412555.2021.1955338 .

Abstract
Introduction: In a subset of chronic obstructive pulmonary disease (COPD)patients the course of the disease is complicated by a severe acute exacerbations (AECOPD) that may require hospitalization, at which time negative outcomes may occur up to 30 days after discharge. Several predictors of negative outcomes have been documented.Areas covered: We considered five negative outcomes related to patients hospitalized with AECOPD: treatment failure, noninvasive mechanical ventilation (NIMV) failure, prolonged length of hospital stay (LHS), short-term mortality (≤ 90 days from admission and including the in-hospital mortality), and early readmission (≤30 days from discharge). Possible therapeutic and preventive strategies to improve these outcomes are outlined and discussed.Expert opinion: Several strategies have been proposed to improve outcomes. Among these, steroid or antibiotic use may reduce the risks of treatment failure or of prolonged hospital stay. We note that operator-related factors may influence the outcome of NIMV. However, little has been documented about the short-term mortality or early readmission rates. In general, few interventions consistently improve negative outcomes and prognosis of AECOPD.
