What is known and objective: Chronic obstructive pulmonary disease (COPD) is associated with significant morbidity and mortality, and frequent exacerbations are associated with an increased risk of death, deterioration in lung function and reduced quality of life. Current Australian guidelines developed by the Lung Foundation of Australia (the COPD-X Plan) recommends the use of a short course of corticosteroids and oral antibiotics (amoxycillin or doxycycline) as part of the treatment of an AECOPD; however, it was noted that clinical practice at the study hospital had deviated from these guidelines. To evaluate the antibiotic prescribing practices in acute exacerbations of chronic obstructive pulmonary disease (AECOPD) patients, and to compare the differences in clinical outcomes (primarily mean length of stay and the rate of unplanned readmissions) between patients who received broad- vs. narrow-spectrum antibiotics in a large regional hospital.

Methods: Retrospective audit of medical records for patients admitted with uncomplicated AECOPD during January-September, 2014 in a 224 acute bed regional hospital in Victoria, Australia.

Results and discussion: Fifty-nine per cent of patients received broad-spectrum antibiotics (ceftriaxone), whereas only 10% of prescriptions were concordant with current Australian guideline recommendations. Patients receiving a broad-spectrum regimen were more likely to be older (749 vs. 699 years; P = 0009), have a higher COPD severity score (i.e. BAP-65 score, 155 vs. 106; P = 0002) and a higher CRP (592 vs. 255 mg/L; P = 0003) on admission. The mean LOS was not significantly different between those who received ceftriaxone and those who did not (509 vs. 455 days; P = 047). There was no significant difference between the groups in rates of readmissions.

What is new and conclusion: The antibiotic prescribing patterns for AECOPD in rural and regional Australian hospitals have not previously been examined in the current literature. In the study hospital, the majority of patients received broad-spectrum antibiotics in the initial treatment of AECOPD. No differences in hospital length of stay, or rate of readmission for AECOPD were observed between those who received broad- and narrow-spectrum antibiotics.
