Medication adherence is poor for patients with chronic obstructive pulmonary disease (COPD) in the US, with many under- or over-utilizing prescriptions and using inhalers incorrectly. Adherence varied by medication type and situation, not demographics.

Area of Science:

  • Pulmonary Medicine
  • Pharmacology

Background:

  • Effective management of chronic obstructive pulmonary disease (COPD) is challenged by poor patient adherence to prescribed medication regimens.
  • Limited data exist on medication adherence specifically for COPD patients within the United States.

Purpose of the Study:

  • To investigate medication adherence patterns among COPD outpatients in the southeastern United States.
  • To identify factors associated with adherence, including prescription complexity, medication classes, and situational variables.

Main Methods:

  • A study was conducted with 78 COPD outpatients from a southeastern US medical center.
  • Data collected included prescribed medications (average 6.26 per patient), dosing schedules, administration modes, and adherence behaviors.
  • Adherence was assessed by examining medication underutilization, overutilization during exacerbations, and inhaler technique.

Main Results:

  • Poor adherence was prevalent: 54% underutilized medications, 50% overutilized during respiratory distress, and 31% used ineffective inhaler techniques.
  • No association was found between adherence and demographic variables.
  • Adherence was significantly related to specific medication classes and situational factors.

Conclusions:

  • Significant medication adherence issues exist for US COPD patients, impacting effective disease management.
  • Adherence is influenced by medication type and patient-specific circumstances rather than demographics.
  • Interventions should address medication complexity and situational triggers to improve COPD patient adherence.
