5. Conclusion
Polypharmacy is common in both older and middle-aged people with diabetes, with increasing trends in the study period, particularly in patients between 55-64 years of age. Despite an increase in polypharmacy, we observed a decrease in PIM prevalence in patients of 65 years and older with polypharmacy. No decrease was seen for middle-aged patients with polypharmacy. The most common PIMs in people with diabetes were similar to those seen in the general population. Further efforts are needed to decrease the use of PIMs in populations already burdened with many drugs.
