Emergency department management of exacerbation of chronic obstructive pulmonary disease: audit of compliance with evidence-based guidelines.

BACKGROUND: Emergency departments (ED) play a key role in management of exacerbation of chronic obstructive airways disease (COPD). Current guidelines for management of exacerbation of COPD showed highest levels of evidence (Level A and B) were related to use of medications and non-invasive positive pressure ventilation (NIPPV).

AIMS: The aim of this study was to examine compliance with high level evidence for management of exacerbation of COPD during the first 4 h of ED care.

METHODS: A retrospective medical record audit was conducted at four public and one private ED in Melbourne, Australia. Participants were adult patients with COPD presenting to the ED with a primary complaint of shortness of breath from July 2006 to July 2007. Outcome measures were compliance with evidence-based recommendations regarding use of bronchodilators, methylxanthines, steroids and NIPPV.

RESULTS: Of 273 patients in this study, 72.4% received short-acting beta-agonist bronchodilators, 37.8% received an inhaled short-acting anticholinergic medication and 56.6% received systemic steroid therapy. NIPPV was used in 21 patients, 15 of whom had documentation of acidosis and/or hypercapnia).

CONCLUSIONS: There was variation in the use of high level evidence for the ED management of exacerbation of COPD. The highest rate of compliance was non-use of methylxanthines and the greatest deficit was poor compliance with evidence related to NIPPV. There was also scope for improvement in the use of bronchodilators and systemic steroids.
