Abstract Objective: Chronic obstructive pulmonary disease (COPD) has been associated with several complications and mortality in acutely ill patients. For patients with aneurysmal subarachnoid hemorrhage (aSAH), the association between COPD and clinical outcomes remains unclear. Methods: In this retrospective cohort study, we analyzed consecutive aSAH patients admitted to the West China Hospital between 2009 and 2019. Propensity score matching was performed to obtain the adjusted odds ratios (ORs) with 95% CI. The primary outcome was in hospital mortality.Results: Using a ten-year clinical database from a large university medical center, 5643 patients with aSAH were identified, of whom 377 (7.9%) also had COPD. After matching, 289 patients were included in COPD group and 1156 in non-COPD groups. COPD was associated with increased in-hospital mortality (OR 1.63, 95% CI 1.02-2.62) and poor functional outcome at discharge (OR 1.37, 95% CI 1.04-1.80). Similarly, patients with COPD had significantly longer length of hospital stay, higher odds of seizure (OR 2.05, 95% CI 1.04-4.04), pneumonia (OR 3.10, 95% CI 2.38-4.04), intracranial infection (OR 1.62, 95% CI 1.14-2.29), urinary tract infection (OR 1.59, 95% CI 1.16-2.20) and bloodstream infection(OR 3.27, 95% CI 1.74-6.15). Conclusions: Among aSAH patients, COPD is associated with increased mortality. COPD represents a significant risk factor for pneumonia and seizure.

Purpose: Many comorbidities, including depression, anxiety, and insomnia, occur in patients with chronic obstructive pulmonary disease (COPD). These patients may be prescribed benzodiazepines (BZDs). However, there are some concerns that benzodiazepines increase the risk of drug overdose, hypercapnic respiratory failure, acute exacerbation and increased mortality. The aim of our study was to evaluate the drug safety of BZDs in patients with COPD.Methods: We used the National Health Insurance Research database in Taiwan from 2002 to 2016 to perform a retrospective cohort study. We enrolled patients who were exposed to the first prescription of BZDs, non-BZDs or a combination (mix user) after COPD diagnosis. We performed 1:1:1 propensity score matching in three groups. The outcomes were COPD with acute exacerbation and all-cause mortality. Poisson regression analysis was performed to evaluate the incidence rate ratios for the outcomes in the groups.Results: After propensity score matching, there were 2,856 patients in each group. After adjusting for confounding factors, we found that compared to BZD users, non-BZD and mix users had nonsignificant differences in outpatient management of acute exacerbations, hospitalization management of acute exacerbations, emergency department management of acute exacerbations and all-cause mortality. BZD and mix groups showed significantly increased admission for acute exacerbation of COPD compared with that of the nonuser group, with IRRs of 2.52 (95% CI, 1.52–4.18; p = 0.0004) and 2.63 (95% CI, 1.57–4.40; p = 0.0002), respectively.Conclusion: BZD, non-BZD, and mix users showed increased COPD-related respiratory events compared to nonusers in Asian subjects.

Abstract Many comorbidities, including depression, anxiety, dyspnea, and insomnia, occur in patients with chronic obstructive pulmonary disease (COPD). These patients may be prescribed benzodiazepines (BZDs). However, there are some concerns that benzodiazepines increase the risk of drug overdose, hypercapnic respiratory failure, acute exacerbation and increased mortality. The aim of our study was to evaluate the drug safety of BZDs in patients with COPD. We used the National Health Insurance Research Database (NHIRD) in Taiwan from 2002 to 2016 to perform a retrospective cohort study. We enrolled patients who were exposed to the first prescription of BZDs, non-BZDs or a combination (mix user) after COPD diagnosis. We performed 1:1:1:1 propensity score matching in three groups. The outcomes were COPD with acute exacerbation and all-cause mortality. Poisson regression analysis was performed to evaluate the incidence rate ratios (IRRs) for the outcomes in the groups. After propensity score matching, there were 2856 patients in each group. After adjusting for confounding factors, we found that compared to BZD users, non-BZD and mix users had nonsignificant differences in outpatient management of acute exacerbations, hospitalization management of acute exacerbations, emergency department management of acute exacerbations and all-cause mortality. Using BZDs or non-BZDs is safe in terms of COPD exacerbation. However, BZD, non-BZD, and mix users showed increased COPD-related respiratory events compared to nonusers.

ObjectivesAortic aneurysm (AA) is a leading cause of death worldwide. Chronic obstructive pulmonary disease (COPD) is a risk factor for AA, and the prognoses of COPD patients with AA who underwent/did not undergo an operation warrant investigation.DesignA nationwide retrospective cohort study.SettingWe included patients with AA older than 18 years who received their first AA diagnosis between 2005 and 2011 in Taiwan.ParticipantsThis study enrolled 3263 COPD patients with AA before propensity score matching and 2127 COPD patients with AA after propensity score matching.Outcome measuresThe main outcomes were all-cause mortality and rehospitalisation for AA or operation. The outcomes of COPD patients with AA and COPD patients without AA during an 8-year follow-up period were examined using Cox proportional hazards models.ResultsIn the AA population, patients with COPD showed higher rates of mortality and rehospitalisation than patients without COPD with adjusted HRs of 1.12 (95% CI 1.03 to 1.22) and 1.11 (95% CI 1.01 to 1.23), respectively, after propensity score matching. Analysis of the patients who underwent an operation revealed that the rates of mortality of COPD and non-COPD patients were not significantly different. In contrast, among the patients who did not receive an operation, patients with COPD showed a higher mortality rate than patients without COPD with an adjusted HR of 1.11 (95% CI 1.0 to 1.22).ConclusionsThe outcomes of COPD patients with AA undergoing an operation were improved, but the mortality rate of non-COPD patients with AA remained high. An effective treatment to reduce mortality in this group warrants further investigation.
