Patient adherence with COPD therapy

CORRESPONDENCE: C. S. Rand, Johns Hopkins School of Medicine, 5501 Hopkins Bayview Circle, Baltimore, MD 21224, USA. Fax: 1 4105502612. E-mail: crand1{at}jhmi.edu

Although there are very few published studies on adherence to treatment regimens in chronic obstructive pulmonary disease (COPD), the evidence that exists suggests that, as with asthma therapy, adherence is poor.

Patient beliefs about COPD, as well as their motivation and expectations about the likelihood of success of medical interventions, can influence adherence rates. Other critical factors include the patient's understanding of their illness and therapy, and the complexity of the prescribed treatment regimen. Incorrect inhaler technique is also a common failing.

When prescribing in primary or specialist care, healthcare professionals should address adherence as a vital part of the patient consultation. Improved patient education may also increase adherence rates.
