1 Interven'ons that Improve Outcomes of COPD Sidney S. Braman MD FCCP Professor of Medicine The Ichan School of Medicine at Mount Sinai New York, NY

2 Disclosures Consultant Sunovion, BI, Forest, Meda Reference to studies of drugs not approved for COPD exacerba'on

3 Interven'ons that Improve Outcomes of COPD Objec'ves: 1. Recognize the COPD risk factors that lead to hospital admission 2. Discuss the evidence- based hospital protocols to improve symptoms and other outcomes of the COPD exacerba'on 3. Iden'fy the high risk co- morbidi'es of COPD that may lead to a COPD readmission 4. List the reasons for poor adherence to therapy and how to improve low adherence rates

4 Interven'ons that Improve Outcomes of COPD 1. Iden'fy the High Risk Pa'ent

5 Interven'ons that Improve Outcomes of COPD: 1. Iden'fy the High Risk Pa'ent Severity of airway obstruction (FEV1 impairment) Chronic bronchial mucous hypersecretion (productive cough) Poor health-related quality of life Increased age and duration of COPD Prior use of medications for COPD, especially PO steroids Bacterial colonization Comorbid conditions (e.g., cardiovascular disease) Antibiotic or systemic corticosteroid use in the past year Pulmonary Artery to Aorta ratio (PA:A) > 1 Failure to use Oxygen (LTOC) when needed Poor Adherence to medication

6 Interven'ons that Improve Outcomes of COPD 1. Iden'fy the High Risk Pa'ent 2. Use evidence- based hospital protocols

7 Which of the following has been shown to reduce the risk re- exacerba'on within 30 days? a. b. c. d. Course of prednisone for 2 weeks Dietary protein supplementa'on Home- based pulmonary rehabilita'on Nocturnal BiPAP ven'la'on

8 Evidence- Based Hospital Protocols Assess severity of symptoms, blood gases, chest radiograph Give supplemental O2 therapy; obtain serial ABG measurements Give Bronchodilators Add oral or intravenous cor'costeroids Consider an'bio'cs (oral or occasionally intravenous) when signs of Consider noninvasive mechanical ven'la'on At all 'mes: Monitor fluid balance and nutri'on Consider subcutaneous heparin or low molecular weight heparin Iden'fy and treat associated condi'ons (e.g., heart failure, arrhythmias) Closely monitor condi'on of the pa'ent (GOLD) http//

9 Evidence- Based Hospital Protocols Short- ac'ng inhaled beta2- agonists with or without short- ac'ng an'cholinergics are usually the preferred bronchodilators- Evidence C (no controlled trials) No difference MDI + spacer vs. nebulizers Methyl Xanthines-?? Evidence B Cor'costeroids Evidence A An'bio'cs Three cardinal symptoms (Evidence B); Two cardinal symptoms with purulent sputum (Evidence C) Mechanical ven'la'on (invasive or noninvasive) (Evidence B) Length of an'bio'c therapy is usually 5-10 days (Evidence D).

30 Reduce Exacerba'on Risk Factors: Influenza Vaccina'on Evidence from randomized clinical trials indicates that inac'vated influenza vaccine reduces exacerba'on rates in COPD pa'ents The magnitude of this benefit is similar to that seen in large observa'onal studies and was due to a reduc'on in late exacerba'ons occurring 3 or more weeks aner vaccina'on and due to influenza A mild increase in transient local adverse effects with vaccina'on is observed, but there was no evidence of an increase in exacerba'ons occurring within 2 weeks of vaccina'on Poole PJ, et al.
