Background
Antibiotics are often prescribed for hospitalized patients with chronic obstructive pulmonary disease (COPD) exacerbations. The use of procalcitonin (PCT) in the management of pneumonia has safely reduced antibiotic durations, but limited data on the impact of PCT guidance on the management of COPD exacerbations remain.
Objective
To determine the impact of PCT guidance on antibiotic utilization for hospitalized adults with exacerbations of COPD.
Design
A retrospective, pre-/post-intervention cohort study was conducted to compare the management of patients admitted with COPD exacerbations before and after implementation of PCT guidance. The pre-intervention period was March 1, 2014, through October 31, 2014, and the post-intervention period was March 1, 2015, through October 31, 2015.
Participants
All patients with hospital admissions during the pre- and post-intervention period with COPD exacerbations were included. Patients with concomitant pneumonia were excluded.
Intervention
Availability of PCT laboratory values in tandem with a PCT guidance algorithm and education.
Main Measures
The primary outcome was duration of antibiotic therapy for COPD. Secondary objectives included duration of inpatient length of stay (LOS) and 30-day readmission rates.
Key Results
There were a total of 166 and 139 patients in the pre- and post-intervention cohorts, respectively. There were no differences in mean age (66.2 vs. 65.9; P = 0.82) or use of home oxygenation (34% vs. 39%; P = 0.42) in the pre- and post-intervention groups, respectively. PCT guidance was associated with a reduced number of antibiotic days (5.3 vs. 3.0; p = 0.01) and inpatient LOS (4.1 days vs. 2.9 days; P = 0.01). Respiratory-related 30-day readmission rates were unaffected (10.8% vs. 9.4%; P = 0.25).
Conclusions
Utilizing PCT guidance in the management of COPD exacerbations was associated with a decreased total duration of antibiotic therapy and hospital LOS without negatively impacting hospital readmissions.
