Backgrounds: Chronic obstructive pulmonary disease (COPD) is a leading cause of death and major health problem and costs in Thailand. Patient adherence in COPD is essential to optimize disease control. However in real life practice, poor adherence to inhalation medication is common. At COPD clinic, pharmacists play a critical role for help patients understand the disease, educate inhaler devices technique to improve adherence and that it might increase lung functions.
Methods: A descriptive study of 85 COPD patients who consecutively follow up at least 4 times per year at one stop service COPD clinic from January 2012 to January 2013 before and after pharmacist interventions in term of adherence and lung functions. Interventions included counseling, teaching and demonstration device one by one.
Results: Before pharmacist interventions, we found that patients with good adherence was 31.8% and after interventions by brief counseling of disease knowledge and demonstration inhaler devices technique adherence increase to 47.1%, 51.8% in 3 months and 1 year follow up (p<0.05).The peak expiratory flow rates and FEV1 measured before and after improved with statistical significance (p<0.05). Patients satisfactions was also increased significantly (p<0.05).
Conclusions: Pharmacist interventions in COPD patients at one stop service clinic can intervene to help patients improve their adherence and patients satisfaction.
