Profiles and Patterns of Medication Use among Older Adults with Osteoarthritis

The symptoms of osteoarthritis(OA) are frequently managed with oral drugs, yet these medications are associated with a number of potentially serious adverse effects. Age-related changes and the presence of co-existing chronic diseases can increase the risk of drug-related problems. In addition, the chronic nature of osteoarthritis results in long-term use of medications and suggests variation in drug use over time. Our OA cohort offers a unique opportunity to study the patterns of medication use over time among a cohort of older adults with osteoarthritis. This research seeks to describe and explain patterns of medication use in this population, focusing specifically on the inappropriate under- and over-utilization of pain medication, and potentially high-risk drug-drug and drug-disease combinations.
