LA inhalers for COPD: perceptions/reality of ABCD GOLD tool use

Abstract

Background: The Global Initiative for Chronic Obstructive Lung Disease (GOLD) created an ABCD tool to assess staging and severity of COPD subgroups that respond to LAMA or LABA with improved quality of life and reduced exacerbations. Our study assesses perception of physicians at five community hospitals towards LAMA use for patients admitted with COPD exacerbations according to the GOLD guidelines and describes the experience at our hospital. Methods: Electronic survey forms regarding LAMA use and the GOLD criteria ABCD for COPD treating physicians were sent to five hospitals. A one-year chart review at our hospital determined prevalent use of a maintenance LAMA or LABA inhaler in patients admitted with acute COPD exacerbation. Currently, our EMR does not require a field for the GOLD ABCD categorization. Results: We obtained a 33% (45/136) response rate. Of these, 63% felt a LAMA to be essential on formulary; 60% were neutral or unlikely to initiate LAMA on admission; 47.7% likely or very likely to start a LAMA during hospitalization; 82% were neutral to very likely to discharge a patient on a LAMA if deemed necessary for maintenance. Of those admitted for acute COPD exacerbations to our hospital, over a third of COPD patients were not on a maintenance LAMA or LABA. Conclusions: Most physicians felt it important to prescribe a maintenance LAMA to COPD patients hospitalized for acute exacerbation. Our hospital's use of LAMA or LABA demonstrates the need to incorporate strategies to encourage appropriate prescribing of these LA inhalers per GOLD guidelines.
