Non-adherence to treatment is a world-wide problem and the impact of poor adherence grows as the burden of chronic diseases grows world wide.
- Adherence to long-term therapy for chronic illnesses in developed countries averages 50%.1
- Hypertension,dyslipidaemia and diabetes mellitus:67-76% (MPR)2
- COPD:44% (MPR)3
Therapeutic non-adherence is a major issue in health care. The consequences of non-adherence to long-term therapies: poor health outcomes and increased health care costs.1
- Non-adherence may contribute to:
48% of asthma deaths
80% increase risk of death in diabetes
3.8 times increased risk of death in the year following an MI 4
Increasing the effectiveness of adherence interventions may have far greater impact on the health of the population than any improvement in specific medical treatments.5
