Chronic Obstructive Pulmonary Disease (COPD Clinical Trial
Official title:
A Randomized Clinical Study to Assess the Impact of Symbicort® pMDI Medication Reminders on Adherence in COPD Patients
A randomized clinical study to assess the impact of Symbicort® pMDI medication reminders on adherence in COPD patients
Chronic obstructive pulmonary disease (COPD) is a common disease with substantial associated morbidity and mortality. COPD is the third leading cause of death in the US and claimed 133,965 US lives in 2009. In 2011 12.7 million US adults were estimated to have COPD. However, approximately 24 million US adults have evidence of impaired lung function, indicating an under diagnosis of COPD. COPD also has a potentially harmful economic impact. In 2010, COPD resulted in over 10 million office visits, nearly 1.5 million emergency department visits, 700,000 hospitalizations, and 133,575 deaths in the US. In 2010, US total medical treatment costs attributed solely to COPD (i.e., excluding comorbidities) were estimated to be $32.1 billion with an additional $3.9 billion in COPD costs resulting from worker absenteeism. Even in industrialized countries such as the US, where anti-smoking initiatives have been relatively successful, the legacy of past smoking behavior in aging populations ensures that the COPD burden will unavoidably continue to climb over the next 20 to 30 years. Adherence rates for inhaled combination therapy is poor (average 3.9 refills per year). COPD patients with lower adherence tend to have higher overall healthcare costs, as demonstrated in a 24 month study of 33,816 patients in the US, which found: Patients continuing therapy had lower costs of care by $3764 compared with patients who had ceased to take their maintenance therapy. COPD patients with higher adherence to prescribed regimens experienced fewer hospitalizations and lower Medicare costs (-$2185) than those who exhibited lower adherence behaviors. Given the poor adherence with inhaled combination therapy seen in patients with COPD, and associated morbidity/mortality and economic costs, the present study is being conducted to see if medication reminders can be used to improve adherence in this population. ;
