Summary
This study looked at whether a DNA test (pharmacogenomics) could help doctors choose the right medications for older adults taking five or more drugs. Researchers tested 66 participants and measured how often the results led to medication changes. The goal was to see if this approach could improve safety and lower healthcare costs.
