Evaluation of Inhaler Prescribing Trends in Hospitalized Patients With Suspected but Unconfirmed Chronic Obstructive Pulmonary Disease.

BACKGROUND

The Global Initiative for Chronic Obstructive Lung Disease (GOLD) report recommends initial bronchodilator therapy over inhaled corticosteroids (ICS) for most patients. However, real-world prescribing often diverges. Management is further complicated in hospitalized patients with suspected but unconfirmed chronic obstructive pulmonary disease (COPD), where providers must decide on therapy initiation and outpatient follow-up.

OBJECTIVE

To describe inhaler prescribing in suspected but unconfirmed COPD upon hospital discharge.

METHODS

This was an institutional review board-approved retrospective cohort study of patients of ages 40 years or older with a smoking history of at least 10-pack years, but without a prior COPD diagnosis, who presented with a suspected COPD exacerbation or acute respiratory failure secondary to suspected COPD. The primary outcome was inhaler prescribing at discharge. Secondary outcomes included confirmed COPD diagnosis, guideline concordance, hospital readmission for a COPD exacerbation, and ICS-related adverse events within 180 days.

RESULTS

Of the 51 patients included in the study, 29 (56.9%) were prescribed new inhalers, with 15 (29.4%) prescribed ICS-containing regimens. Following discharge, 15 patients (29.4%) completed pulmonary function testing, with 8 (15.7%) receiving a COPD diagnosis. Guideline concordance could not be assessed due to absent documentation. Eight patients (15.7%) were readmitted with a COPD exacerbation, and 13 ICS-related adverse events were documented. Limitations include the sample size and retrospective study design.

CONCLUSION

This study found a high frequency of initial ICS prescribing for suspected but unconfirmed COPD, as well as limited follow-up and diagnostic reassessment. These findings highlight the need for system-level interventions to optimize discharge prescribing and ensure timely follow-up.
