Evaluation of the quality of emergency department management for patients with chronic obstructive pulmonary disease.

Chronic obstructive pulmonary disease (COPD) is associated with exacerbations and high risk of serious outcomes. Our goal was to determine the appropriateness of the emergency department (ED) management of COPD exacerbations. This observational cohort study incorporated a health records review and included COPD exacerbation cases seen at two large academic EDs. We included all patients with the primary diagnosis of COPD exacerbation. From the electronic medical record, demographic and clinical data were abstracted, and the Ottawa COPD Risk Score (OCRS) was calculated for each. Short-term serious outcomes included intensive care unit admission, intubation, myocardial infarction, noninvasive positive pressure ventilation (NIV), and death at 30 days. Cases were judged for appropriateness of treatment according to explicit indications and standards developed a priori. We enrolled 500 cases with mean age of 71.9 years, 51.2% female patients, 50.2% admitted, and 4.4% death. The calculated OCRS score was >2 for 70.8% of patients. The treatments provided were inhaled β-agonists (82.6%), inhaled anticholinergics (76.6%), corticosteroids (75.2%), antibiotics (71.0%), oxygen (63.8%), NIV (8.8%), and intubation (0.6%). Overall, 50.0% of cases were judged to have had inadequate management due to missing treatments. Specifically, the proportion of missing treatments were inhaled β-agonist (17.0%), inhaled anticholinergic (22.6%), corticosteroids (24.4%), antibiotics (12.8%), and NIV (2.0%). Adequate treatment of COPD exacerbation was lacking in 50.0% of patients in these two large academic EDs. Concerning were the number of patients not receiving corticosteroids or antibiotics. Implementation of explicit treatment standards should lead to improved patient care of this common and serious condition.

Antibiotic treatment for patients with exacerbation of chronic obstructive pulmonary disease: A systematic review and meta-analysis

BackgroundAlthough respiratory tract infection is a significant factor that triggers exacerbation of chronic obstructive pulmonary disease (COPD), the benefit of antibiotics for patients with COPD exacerbation remains controversial. It is necessary to evaluate the efficacy and safety of antibiotics versus placebo in such patients. MethodsWe conducted a systematic review and meta-analysis of randomized controlled trials of antibiotics versus placebo for the treatment of COPD exacerbation, and compared the frequencies of treatment failure, mortality, and adverse events between patients treated with antibiotics and those treated with placebo. ResultsA total of six studies were included in this meta-analysis. The frequency of treatment failure was significantly lower in the antibiotic-treated patients compared to the placebo-treated patients (odds ratios [OR] 0.50, 95% confidence intervals [CI] 0.35–0.71, p = 0.0001). There was no significant difference between the two groups in mortality (OR 0.44, 95% CI 0.05–3.76, p = 0.45) or frequency of adverse events (OR 1.05, 95% CI 0.75–1.48, p = 0.78). ConclusionIn the current systematic review and meta-analysis, we found that antibiotics were superior to placebo in patients with exacerbated COPD, as shown by the lower treatment failure rate.

A comparative study of platelet indices in stable versus acute exacerbation of chronic obstructive pulmonary disease

Background and Objectives: Chronic obstructive pulmonary disease (COPD) is a major global health problem. A strategy for prevention and early treatment of COPD exacerbations is essential to better address the disease. Hence, the study was undertaken to compare the various platelet indices in patients with acute exacerbation versus stable COPD and study the relationship of these indices with the severity of COPD exacerbation to aid in better patient management. Methodology: The study was conducted at the hospitals attached to Bangalore Medical College and Research Institute from November 2017 to May 2019, on patients with stable and acute exacerbation of COPD. Brief history with relevant investigations was performed. Platelet indices were compared between the two groups. The relationship between the platelet indices and the severity of acute exacerbation of COPD was also studied. Results: Among the platelet indices, there was a statistical difference in the mean values of mean platelet volume (MPV) and platelet distribution width (PDW) in the two groups. The MPV and PDW values were 8.85 fL and 7.91 fL and 15.94% and 17.14%, respectively, during the stable period and exacerbations of COPD, respectively. Furthermore, in our study, it was found that there was no significant association between the degree of hypoxia and the platelet indices. Conclusion: Among the various platelet indices, our study suggests that the MPV reduced and PDW increased in patients with acute exacerbation when compared to stable COPD. Furthermore, our study did not show any significant correlation between the platelet indices and the severity of COPD as determined by the degree of hypoxia.

Impact of antibiotic choice on readmission in adults experiencing an acute COPD exacerbation.

The impact of antibiotic therapy in managing acute chronic obstructive pulmonary disease (COPD) exacerbations requiring hospitalization remains unclear. We conducted a study to assess the impact of antibiotic therapy on the rate of 30-day readmission after discharge from a hospital stay for an acute COPD exacerbation. Additional study outcomes analyzed included the effects of antibiotic therapy on hospital length of stay, in-hospital mortality, 90-day and 12-month readmission rates, and time to next COPD exacerbation. The study was an institutional review board-approved, retrospective, observational review of adult patients at a tertiary academic medical center. The medical records of patients 18 years of age or older who were hospitalized for an acute COPD exacerbation between January 2008 and December 2014 were evaluated. Included patients were stratified by receipt of guideline-appropriate, guideline-inappropriate, or no antibiotic therapy. Nonparametric data were analyzed using the Kruskal-Wallis test (nonparametric) and categorical data via χ 2 test, respectively. Three hundred twenty-five subjects were included; there were no significant differences in baseline characteristics in the 3 study groups. Sixty-eight percent of patients (n = 223) received antibiotics. The percentage of patients readmitted within 30 days did not differ between cohorts: 11.9% (appropriate therapy) vs 13.2% (nonappropriate therapy) vs 12.2% (no antibiotics) (P = 0.95 for all comparisons). Additionally, no detectable differences in 90-day or 12-month readmission rate, length of hospital day, or in-hospital mortality were found. However, a trend toward increased time to next COPD exacerbation was noted in those receiving antibiotics vs no antibiotics (352 days vs 192 days, P = 0.07). Treatment of COPD exacerbations with antibiotics did not impact readmission rates, length of hospital stay, in-hospital mortality, or time to next exacerbation. More investigation is warranted to assess the effect of antibiotics on time to next exacerbation, as well as comparative effectiveness between antibiotic classes.

Comparative efficacies of nebulized budesonide and systemic corticosteroids in the treatment of exacerbations of chronic obstructive pulmonary disease: A systematic review and meta-analysis.

Corticosteroids are recommended by almost all international guidelines for the management of exacerbations of chronic obstructive pulmonary disease (COPD). Nevertheless, due to their side effects, there are still concerns regarding the use of systemic corticosteroids (SCs). The Global Initiative for Chronic Obstructive Lung Disease guideline states nebulized budesonide (NB) may be a suitable alternative to SCs for treating COPD exacerbations. We conducted this study to systematically compare the efficacies of NB and SCs by using a meta-analysis. PubMed, EMBASE and Cochrane Library databases were searched from database inception to 10 October 2019. Our main end points were change in pulmonary function and blood gas analysis. Secondary end points were numbers of exacerbations and hyperglycaemia. Of 645 identified studies, 6 were eligible and were included in our analysis (N=867 participants). Compared with SCs, NB was non-inferior on the change in FEV1 %predicted at 24hours, 48-72hours and 5-7days; FEV1 at 5-7days; FEV1 /FVC at 7days. For blood gas analysis, our meta-analysis indicated that PaO2 , PaCO2 at 24hours, 48-72hours and 7-10days and SaO2 at 24hours and 7-10days showed a non-significant difference in both groups, whereas the SaO2 was significant higher in NB group at 48-72hours after treatment. Hyperglycaemia was less frequent with NB (odds ratio, 0.1; 95% CI, 0.01-0.85; P=.04). Based on our meta-analysis, NB was not inferior to SCs when used in the treatment of COPD exacerbations. However, additional well-designed prospective studies are needed to identify the optimal dose of nebulized budesonide and the effects of nebulized budesonide in outpatients, or patients in ICU settings.

Clinical Role of the Chronic Obstructive Pulmonary Disease Assessment Test in Prediction of the Response to Treatment for Exacerbations.

BackgroundThe chronic obstructive pulmonary disease (COPD) assessment test (CAT) is a validated, eight-item questionnaire used to quantify the health status of patients. The aim of this study was to evaluate the usefulness of the CAT questionnaire as a tool to assess the response to treatment in acute exacerbations of COPD in an outpatient setting.MethodsA multicenter, phase 3 randomized controlled trial was conducted previously to examine the efficacy and safety of oral zabofloxacin for the treatment of COPD exacerbations. In the present post hoc analysis of the original study, patients with COPD exacerbation were categorized as responders or non-responders according to the respiratory symptoms persisting on day 10 (visit 3) of treatment. The CAT questionnaire was completed daily by patients at home from the initial visit to the second visit on day 5. Subsequently, the questionnaire was completed in the presence of a physician on days 10 (visit 3) and 36 (visit 4). Multivariate regression analysis was performed to determine the association between CAT scores and the therapeutic response.ResultsThe CAT scores decreased more rapidly in responders compared to non-responders during the first 5 days (23.3–20.4 vs. 23.5–22). Among responders, patients with higher severity of illness also revealed higher CAT scores on the first day of an exacerbation (mild, 19.8; moderate, 21.4; severe, 23.8; very severe, 28.6). Multivariate analysis revealed that a change in the CAT score during the first 3 days influenced the therapeutic response. A significant decrease in scores in the domains of sputum production, chest tightness, and activities of daily living was seen among responders.ConclusionEarly improvement in CAT scores may be associated with a more favorable response to the treatment of COPD exacerbations.Trial RegistrationClinicalTrials.gov Identifier: NCT01658020Trial RegistrationClinical Research Information Service Identifier: KCT0000532

The Impact of Interprofessional Monitoring and Education on the Usage of Systemic Glucocorticoids in Acute Exacerbations of Chronic Obstructive Pulmonary Disease: A Retrospective, Medication Use Review.

BackgroundSystemic corticosteroid therapy for chronic obstructive pulmonary disease (COPD) exacerbations is routine in clinical practice, however, dosing is variable. The Global Initiative for Chronic Obstructive Lung Disease (GOLD) panel recommends a short course of systemic corticosteroids for acute COPD exacerbation treatment. Despite these recommendations, institutions continue to use higher doses and longer durations of systemic corticosteroid therapies.MethodsThis single-center, retrospective, cohort study evaluated systemic corticosteroid use in inpatient treatment of COPD exacerbations. Data were collected on patients with a diagnosis of COPD exacerbation from October 2017 to February 2018 in both the control and education groups. An interprofessional, learner-centric, quality improvement, educational seminar was performed. Providers were given accompanying pocket reference material for improved adherence to GOLD guidelines for the management of acute COPD exacerbations.ResultsOf the 137 charts reviewed in the control group, 130 of 137 patients (94.9%) received systemic corticosteroid doses exceeding GOLD guideline recommendations. These patients received an average daily dose of 147.5 mg of prednisone equivalents. These patients also experienced more adverse drug reactions as compared to their post-intervention counterparts. The 105 charts examined post-educational intervention revealed 47 of 105 patients (44.8%) received GOLD guideline-directed doses of systemic corticosteroids. This was an improvement from 2.9% (4 of 137) in the control group (p-value < 0.001). The average daily dose decreased to 58 mg daily (p-value < 0.001), and the number of doses over the recommended 40 mg of prednisone equivalents (54 of 105) was a 43.5% reduction (p-value < 0.001). Length of stay also decreased in the education group from 6.1 +/- 4.1 to 4.7 +/- 2.8 days (p-value 0.009). The 30-day readmission rate, however, was not statistically different between the two groups, 31.4% pre- and 21.0% post-educational intervention (p-value 0.098).ConclusionsThe interprofessional education seminar and pocket reference sheet realigned clinical practice with guideline-based therapy in this tertiary care, community hospital. These data validate that learner-centric innovation will benefit patient outcomes and improve the educational potential of the interdisciplinary rounding team.

Optimizing Drug Therapies in Patients with COPD in the US Nursing Home Setting.

Chronic obstructive pulmonary disease (COPD) can be a disabling disease, and the impact on older adults is particularly evident in the nursing home setting. Chronic obstructive pulmonary disease is present in about 20% of nursing home residents, most often in women, and accounts for significant healthcare utilization including acute care visits for exacerbations and pneumonia, as well as worsening heart disease and diabetes mellitus. The emphasis on hospital readmissions is particularly important in nursing homes where institutions have quality measures that have financial implications. Optimizing drug therapies in individuals with COPD involves choosing medications that not only improve symptoms, but also decrease the risk of exacerbations. Optimizing the treatment of comorbidities such as heart disease, infections, and diabetes that may affect COPD outcomes is also an important consideration. Depending on the nursing home setting and the patient, the options for optimizing COPD drug therapies may be limited owing to patient-related factors such as cognition and physical impairment or available resources, primarily reimbursement-related issues. Choosing the best drug therapy for COPD in older adults is limited by the difficulty in assessing respiratory symptoms using standardized assessment tools and potentially decreased inspiratory ability of frail individuals. Because of cognitive and physical impediments, ensuring optimal delivery of inhaled medications into the lungs has significant challenges. Long-acting bronchodilators, inhaled corticosteroids, and roflumilast decrease the risk of exacerbations, although inhaled corticosteroids should be used judiciously in this population because of the risk of pneumonia and oropharyngeal side effects. Treatment of COPD exacerbations should occur early and consideration should be made to the benefits and risks of systemic corticosteroids and antibiotics. Clinical research in the COPD population in nursing homes is clearly lacking, and ripe for discovery of effective management strategies.

CRP-guided antibiotic treatment in acute exacerbations of COPD in hospital admissions.

The role of antibiotics in acute exacerbations of chronic obstructive pulmonary disease (COPD) is controversial and a biomarker identifying patients who benefit from antibiotics is mandatory. We performed a randomised, controlled trial in patients with acute exacerbations of COPD, comparing C-reactive protein (CRP)-guided antibiotic treatment to patient reported symptoms in accordance with the Global Initiative for Chronic Obstructive Lung Disease (GOLD) strategy, in order to show a reduction in antibiotic prescription.Patients hospitalised with acute exacerbations of COPD were randomised to receive antibiotics based either on the GOLD strategy or according to the CRP strategy (CRP ≥50 mg·L-1).In total, 101 patients were randomised to the CRP group and 119 to the GOLD group. Fewer patients in the CRP group were treated with antibiotics compared to the GOLD group (31.7% versus 46.2%, p=0.028; adjusted odds ratio (OR) 0.178, 95% CI 0.077-0.411, p=0.029). The 30-day treatment failure rate was nearly equal (44.5% in the CRP group versus 45.5% in the GOLD-group, p=0.881; adjusted OR 1.146, 95% CI 0.649-1.187, p=0.630), as was the time to next exacerbation (32 days in the CRP group versus 28 days in the GOLD group, p=0.713; adjusted hazard ratio 0.878, 95% CI 0.649-1.187, p=0.398). Length of stay was similar in both groups (7 days in the CRP group versus 6 days in the GOLD group, p=0.206). On day-30, no difference in symptom score, quality of life or serious adverse events was detected.Use of CRP as a biomarker to guide antibiotic treatment in severe acute exacerbations of COPD leads to a significant reduction in antibiotic treatment. In the present study, no differences in adverse events between both groups were found. Further research is needed for the generalisability of these findings.

1479. Evaluating the Impact of Procalcitonin on Antibiotic Utilization in Chronic Obstructive Pulmonary Disease Exacerbations

BackgroundAntibiotic prescription rates for treating exacerbations of chronic obstructive pulmonary disease (COPD) have been reported as high as 90% in the United States. Research has shown that over 50% of COPD exacerbations are due to viral etiologies. Elevations in procalcitonin (PCT) levels can be seen in bacterial infections and can help guide the need for antimicrobial therapy. The goal of this study is to evaluate the impact of PCT on antibiotic use in patients with COPD exacerbations.MethodsWe conducted a retrospective, pre- and post-intervention study. Patients at least 18 years of age, with a diagnosis of COPD exacerbation, and had a PCT level drawn within 24 hours of admission were included. Exclusion criteria included patients presenting with severe trauma, sepsis, bacterial pneumonia, patients who required invasive mechanical ventilation, and patients with an initial admission to the ICU. The primary outcome was antimicrobial duration of therapy. Secondary outcomes included hospital length of stay (LOS), respiratory-related 30-day readmission rates, and treatment failure defined as ICU admission, requirement of invasive mechanical ventilation, or death.ResultsA total of 139 patients were evaluated with 64 and 75 patients in the pre- and post-intervention cohorts, respectively. PCT guidance was associated with a significant reduction in number of antibiotic days of therapy (7.1 days vs. 2.4 days; P < 0.001). A trend in decreasing LOS was observed but did not reach statistical significance (5.3 days vs. 4.1 days; P = 0.080) and respiratory-related 30-day readmission rates did not differ (9.4% vs. 10.7%; P = 0.801). In addition, treatment failure defined as ICU admission (3.1% vs. 0%; P = 0.210), requirement for invasive mechanical ventilation (3.1% vs. 0%; P = 0.210), and death (1.6% vs. 0%; P = 0.460) did not differ significantly between groups.ConclusionImplementation of a PCT-guided protocol for the treatment of COPD exacerbations was associated with a significant reduction in antimicrobial days of therapy. We noted a trend in decreasing LOS and no difference respiratory-related 30-day readmissions, or treatment failure. Our PCT-guided protocol has been demonstrated to safely reduce antibiotic utilization in patients with COPD exacerbations.Disclosures All authors: No reported disclosures.

Changes in biomarkers of cardiac dysfunction during exacerbations of chronic obstructive pulmonary disease.

Cardiac dysfunction is associated with a higher mortality in exacerbations of chronic obstructive pulmonary disease (COPD). It is unknown how the heart responds to treatment of COPD exacerbations. We followed cardiac biomarker levels during hospital admissions for exacerbations of COPD and hypothesised that these biochemical markers of cardiac dysfunction might be affected the severity and treatment of exacerbations of COPD. N-terminal pro-B-type natriuretic peptide (NT-proBNP) and troponin T were measured at admission, 12 h, 72 h, and clinical stability in 176 patients. In a second cohort (n = 93), associations between blood salbutamol concentrations and biomarker changes at 12 h were analysed. NT-proBNP increased from a geometric mean of 43 pmol/L at admission to 56 pmol/L at 12 h (p < 0.001), 53 pmol/L at 72 h (p = 0.045), and decreased to 25 pmol/L (p < 0.001) at stability. Troponin T levels decreased at 12 h (p < 0.001), but 15/174 (9%) patients had a clinically significant rise. Nebulised bronchodilator treatment and blood salbutamol concentrations were associated with greater increases in NT-proBNP rise at 12 h independently of baseline COPD or exacerbation severity and other treatments (p < 0.05). Nebulised bronchodilator and blood salbutamol concentrations also predicted rises in troponin T in univariate analyses (p < 0.05). NT-proBNP continues to rise after admission to hospital for COPD exacerbations and a minority of patients have clinically significant rises in cardiac troponins. These rises were associated with nebulised beta2-agonist treatment. These findings suggest that high doses of beta2-agonists may exacerbate cardiac dysfunction in COPD.

Treatment of COPD Exacerbation in Switzerland: Results and Recommendations of the European COPD Audit

Background: The European COPD Audit initiated by the European Respiratory Society (ERS) evaluated the management of hospital admissions due to exacerbation of chronic obstructive pulmonary disease (COPD) in several European countries. Data on the treatment of severe acute exacerbations of COPD (AECOPDs) in Switzerland are scarce. Objectives: In light of the GOLD 2010 guidelines, this work aims to examine the quality of care for AECOPD and to provide specific recommendations for the management of severe AECOPD in Switzerland. Methods: A total of 295 patients requiring hospital admission to 19 Swiss hospitals due to exacerbation of COPD during a predefined 60 days in 2011 were included in the study. We compared the Swiss data to the official GOLD 2010 recommendations and to the results of the other European countries. Results: Approximately 43% of the Swiss patients with severe AECOPD were current smokers at hospital admission, compared to 33% of the patients in other European countries (p < 0.001). In Switzerland and in Europe, spirometry data were not available for most patients at hospital admission (65 and 60%, respectively; p = 0.08). In comparison to other European countries, antibiotics were prescribed 14% less often in Switzerland (p < 0.001). Only 79% of the patients in the Swiss cohort received treatment with a short-acting bronchodilator at admission. Conclusions: Considering the overall high standard of health care in Switzerland, in light of the GOLD 2010 guidelines we are able to make 7 recommendations to improve and standardize the management of severe AECOPD for patients treated in Switzerland.

Methyl prednisolone vs Dexamethasone in Management of COPD Exacerbation; a Randomized Clinical Trial.

Corticosteroids are routinely used in management of chronic obstructive pulmonary disease (COPD) exacerbation. The main purpose of present study was to compare the efficacy of methyl prednisolone (MP) and dexamethasone (DXM) for this purpose. Adult COPD patients entered the present clinical trial. All patients received standard treatment on admission and were then divided into 2 groups of intravenous MP and DXM. Patients were asked to rate their shortness of breath; sputum volume and viscosity; dyspnea; cough; and general wellbeing on a 0-5 scale. Baseline parameters such as O2 saturation, arterial blood gas parameters, and white blood cell (WBC) count were compared on admission and day 7 and 14 of therapy using SPSS 22. 68 patients were randomly allocated to 2 groups of 34 (82.4% male). The baseline characteristics of the two groups were similar (p < 0.05). Comparison of treatment outcomes for the 7th day showed a significant difference between the 2 groups only regarding cough (p = 0.047), HCO3 (p < 0.001), and O2 saturation (p = 0.042). On day 14 the 2 groups were different only regarding cough (p = 0.048) and sputum viscosity (p = 0.011). There was a significant difference between the two groups regarding trend of changes in dyspnea (p = 0.02; DXM >> MP) and cough (p = 0.035; MP >> DXM). There were no significant differences between the two medications regarding side effects on 7th and 14th day after treatment. It seems that MP and DXM have similar efficacy and side effects in treatment of COPD exacerbation and selecting drug of choice would better be based on the most prominent symptoms of patients on admission.

Do 'guidelines' really guide us?

INTRODUCTION Chronic obstructive pulmonary disease (COPD) is a disease that can be prevented and treated. It is characterized by permanent limitation of the airflow through respiratory tract, which is usually progressive and associated with an increased inflammatory response to noxious particles and gases in the airways and lungs. COPD is currently the fourth leading cause of death in the world. In 2013 Serbian Ministry of Health issued a National guideline for good clinical practice for the diagnosis and treatment of COPD. According to this guide, bronchodilators, administered through inhalation, are basic medications for COPD treatment. The basic treatment of COPD exacerbation involves the use of short-acting beta-2 agonists with or without anticholinergic drugs. Methylxanthines belong to the second-line medications, and they should be used only when short acting beta-2 agonists are not effective. OBJECTIVE The aim of this paper was to determine whether the patients with COPD exacerbation who came to the ambulance station of The City Institute for Emergency Medicine Belgrade (CIEMB) were treated according to the National Guideline. (As of September 2016. there is an inhaler in the ambulance station, as well as the solution for inhalation, salbutamol). Furthermore, we wanted to point out the challenges and limitations of COPD exacerbation treatment at ambulance stations. METHODS We have monitored the work of the CIEMB ambulance station from October 15, 2016, to January 20, 2017. Data on patients' complaints, physical status, diagnosis, and proposed treatment were taken from the regular medical protocols. RESULTS From the 3367 patients enrolled in the ambulance protocol in this period, 86 had the COPD diagnosis. Only 11 of them (12.7 %) were treated according to the National guideline (with inhaling short-acting beta-2 agonist). The others received second-line medications. CONCLUSION Guidelines are designed for the physicians so that they could apply the experiences of best medical practice. They support evidence based medicine and help individuals to combine knowledge and practice, and efficiency and effectiveness. Recently, several studies which monitor the implementation of protocols for COPD treatment were published. All of them indicated presence of deviation from currently valid guidelines. Responsibility for these results is equally borne by physicians, their available resources and patients too, as they often refuse new methods of treatment because they are used to the outdated intravenous therapy. In addition to the continuing education of physicians and constant encouragement for the use of all available new medications, it is necessary to educate patients about modern protocols for the COPD treatment.

Action plans with brief patient education for exacerbations in chronic obstructive pulmonary disease.

Exacerbations of chronic obstructive pulmonary disease (COPD) are a major driver of decline in health status and impose high costs on healthcare systems. Action plans offer a form of self-management that can be delivered in the outpatient setting to help individuals recognise and initiate early treatment for exacerbations, thereby reducing their impact. To compare effects of an action plan for COPD exacerbations provided with a single short patient education component and without a comprehensive self-management programme versus usual care. Primary outcomes were healthcare utilisation, mortality and medication use. Secondary outcomes were health-related quality of life, psychological morbidity, lung function and cost-effectiveness. We searched the Cochrane Airways Group Specialised Register along with CENTRAL, MEDLINE, Embase and clinical trials registers. Searches are current to November 2015. We handsearched bibliographic lists and contacted study authors to identify additional studies. We included randomised controlled trials (RCT) and quasi-RCTs comparing use of an action plan versus usual care for patients with a clinical diagnosis of COPD. We permitted inclusion of a single short education component that would allow individualisation of action plans according to management needs and symptoms of people with COPD, as well as ongoing support directed at use of the action plan. We used standard methodological procedures expected by Cochrane. For meta-analyses, we subgrouped studies via phone call follow-up directed at facilitating use of the action plan. This updated review includes two additional studies (and 976 additional participants), for a total of seven parallel-group RCTs and 1550 participants, 66% of whom were male. Participants' mean age was 68 years and was similar among studies. Airflow obstruction was moderately severe in three studies and severe in four studies; mean post bronchodilator forced expiratory volume in one second (FEV1) was 54% predicted, and 27% of participants were current smokers. Four studies prepared individualised action plans, one study an oral plan and two studies standard written action plans. All studies provided short educational input on COPD, and two studies supplied ongoing support for action plan use. Follow-up was 12 months in four studies and six months in three studies.When compared with usual care, an action plan with phone call follow-up significantly reduced the combined rate of hospitalisations and emergency department (ED) visits for COPD over 12 months in one study with 743 participants (rate ratio (RR) 0.59, 95% confidence interval (CI) 0.44 to 0.79; high-quality evidence), but the rate of hospitalisations alone in this study failed to achieve statistical significance (RR 0.69, 95% CI 0.47 to 1.01; moderate-quality evidence). Over 12 months, action plans significantly decreased the likelihood of hospital admission (odds ratio (OR) 0.69, 95% CI 0.49 to 0.97; n = 897; two RCTs; moderate-quality evidence; number needed to treat for an additional beneficial outcome (NNTB) 19 (11 to 201)) and the likelihood of an ED visit (OR 0.55, 95% CI 0.38 to 0.78; n = 897; two RCTs; moderate-quality evidence; NNTB over 12 months 12 (9 to 26)) compared with usual care.Results showed no significant difference in all-cause mortality during 12 months (OR 0.88, 95% CI 0.59 to 1.31; n = 1134; four RCTs; moderate-quality evidence due to wide confidence interval). Over 12 months, use of oral corticosteroids was increased with action plans compared with usual care (mean difference (MD) 0.74 courses, 95% CI 0.12 to 1.35; n = 200; two RCTs; moderate-quality evidence), and the cumulative prednisolone dose was significantly higher (MD 779.0 mg, 95% CI 533.2 to 10248; n = 743; one RCT; high-quality evidence). Use of antibiotics was greater in the intervention group than in the usual care group (subgrouped by phone call follow-up) over 12 months (MD 2.3 courses, 95% CI 1.8 to 2.7; n = 943; three RCTs; moderate-quality evidence).Subgroup analysis by ongoing support for action plan use was limited; review authors noted no subgroup differences in the likelihood of hospital admission or ED visits or all-cause mortality over 12 months. Antibiotic use over 12 months showed a significant difference between subgroups in studies without and with ongoing support.Overall quality of life score on St George's Respiratory Questionnaire (SGRQ) showed a small improvement with action plans compared with usual care over 12 months (MD -2.8, 95% CI -0.8 to -4.8; n = 1009; three RCTs; moderate-quality evidence). Low-quality evidence showed no benefit for psychological morbidity as measured with the Hospital Anxiety and Depression Scale (HADS). Use of COPD exacerbation action plans with a single short educational component along with ongoing support directed at use of the action plan, but without a comprehensive self-management programme, reduces in-hospital healthcare utilisation and increases treatment of COPD exacerbations with corticosteroids and antibiotics. Use of COPD action plans in this context is unlikely to increase or decrease mortality. Whether additional benefit is derived from periodic ongoing support directed at use of an action plan cannot be determined from the results of this review.

Optimizing identification and management of COPD patients - reviewing the role of the community pharmacist.

The aim of this paper was to propose key steps for community pharmacist integration into a patient care pathway for chronic obstructive pulmonary disease (COPD) management. A literature search was conducted to identify publications focusing on the role of the community pharmacist in identification and management of COPD. The literature search highlighted evidence supporting an important role for pharmacists at each of the four key steps in the patient care pathway for COPD management. Step 1 (primary prevention): pharmacists are ideally placed to provide information on disease awareness and risk prevention campaigns, and to encourage lifestyle interventions, including smoking cessation. Step 2 (early detection/case finding): pharmacists are often the first point of contact between the patient and the healthcare system and can therefore play an important role in the early identification of patients with COPD. Step 3 (management and ongoing support): pharmacists can assist patients by providing advice and education on dosage, inhaler technique, treatment expectations and the importance of adherence, and by supporting self‐management, including recognition and treatment of COPD exacerbations. Step 4 (review and follow‐up): pharmacists can play an important role in monitoring adherence and ongoing inhaler technique in patients with COPD. In summary, pharmacists are ideally positioned to play a vital role in all key stages of an integrated COPD patient care pathway from early disease detection to the support of management plans, including advice and counselling regarding medications, inhaler technique and treatment adherence. Areas requiring additional consideration include pharmacist training, increasing awareness of the pharmacist role, administration and reimbursement, and increasing physician–pharmacist collaboration.

Cigarette smoke alters the ability of human dendritic cells to promote anti-Streptococcus pneumoniae Th17 response.

BackgroundChronic obstructive pulmonary disease (COPD) is associated with chronic inflammation and impaired immune response to pathogens leading to bacteria-induced exacerbation of the disease. A defect in Th17 cytokines in response to Streptococcus pneumoniae, a bacteria associated with COPD exacerbations, has been recently reported. Dendritic cells (DC) are professional antigen presenting cells that drive T-cells differentiation and activation. In this study, we hypothesized that exposure to cigarette smoke, the main risk factor of COPD, might altered the pro-Th17 response to S. pneumoniae in COPD patients and human DC.MethodsPro-Th1 and -Th17 cytokine production by peripheral blood mononuclear cells (PBMC) from COPD patients was analyzed and compared to those from smokers and non-smokers healthy subjects. The effect of cigarette smoke extract (CSE) was analyzed on human monocyte-derived DC (MDDC) from controls exposed or not to S. pneumoniae. Bacteria endocytosis, maturation of MDDC and secretion of cytokines were assessed by flow cytometry and ELISA, respectively. Implication of the oxidative stress was analyzed by addition of antioxidants and mitochondria inhibitors. In parallel, MDDC were cocultured with autologous T-cells to analyze the consequence on Th1 and Th17 cytokine production.ResultsPBMC from COPD patients exhibited defective production of IL-1β, IL-6, IL-12 and IL-23 to S. pneumoniae compared to healthy subjects and smokers. CSE significantly reduced S. pneumoniae-induced MDDC maturation, secretion of pro-Th1 and -Th17 cytokines and activation of Th1 and Th17 T-cell responses. CSE exposure was also associated with sustained CXCL8 secretion, bacteria endocytosis and mitochondrial oxidative stress. Antioxidants did not reverse these effects. Inhibitors of mitochondrial electron transport chain partly reproduced inhibition of S. pneumoniae-induced MDDC maturation but had no effect on cytokine secretion and T cell activation.ConclusionsWe observed a defective pro-Th1 and -Th17 response to bacteria in COPD patients. CSE exposure was associated with an inhibition of DC capacity to activate antigen specific T-cell response, an effect that seems to be not only related to oxidative stress. These results suggest that new therapeutics boosting this response in DC may be helpful to improve treatment of COPD exacerbations.Electronic supplementary materialThe online version of this article (doi:10.1186/s12931-016-0408-6) contains supplementary material, which is available to authorized users.
