Multicenter Study
Determinants of medication underuse and medication overuse in patients with chronic non-malignant pain: a multicenter study.
In chronic non-malignant pain, medication is often used as an important cornerstone of the treatment. Medication non-adherence is a frequent problem in chronic conditions. In patients with chronic non-malignant pain, medication non-adherence ranges between 8% and 53%. Two types of non-adherence can be identified: underuse and overuse of pain medication. ⋯ Patients underusing or overusing their medication do have a different risk profile. The set of determinants of non-adherence, proposed by WHO, is suitable to study determinants of underuse, but the framework is less suitable to study determinants of medication overuse.
