COPD Exacerbation Prevention: April 2015 CHEST Guidelines

The recommendations made in AIM are similar to those in the CHEST guidelines; the lack of breadth in the AIM report reflects new data generated over the last half decade. They include preventing causative exposures (e.g. tobacco, occupational), recommending bronchodilator use (with or without inhaled corticosteroids), possibly using phosphodiesterase-4 inhibitors (PD-4 inhibitors), administering appropriate vaccines, and providing education; however, GOLD does not actually present or rate the evidence associated with those recommendations. GOLD does specifically state that statins have no role in AECOPD prevention, a position that is updated from more recent literature.^8,9

The National Guideline Clearinghouse (NGC) also includes some references to prevention of AECOPD but has no sections explicitly dedicated to prevention. Of note, the NGC still endorses statin use and does not appear to have incorporated data from newer studies.^8,10

Hospitalist Takeaways

Given the high rate of COPD readmissions and its broad impact on morbidity and healthcare costs, measures to prevent COPD exacerbations cannot remain out of scope of care for inpatient physicians. It is important to initiate pulmonary rehab within four weeks of an exacerbation of COPD to prevent future exacerbations. Systems should be put in place to assure that all patients who qualify are vaccinated for influenza and patients who continue to smoke receive cessation counseling.

Today, hospitalists are comfortable with these non-pharmacologic interventions, as well as medications that include inhaled bronchodilators, nebulized medications, macrolide maintenance therapy, and oral steroids; however, other oral medications, such as phosphodiesterase inhibitors, theophylline, and N-acetylcysteine, may be appropriate for select patients, and hospitalists should become more familiar with their utility.^11,12,13,14

Finally, it is important to note that both short- and long-acting inhaled muscarinic antagonists have come to the forefront of pharmacologic interventions for COPD exacerbation prevention.
