The Potential Inappropriate Medication was present in 37.0% (95%CI: 33.5-40.5) of the cases. The Potential Inappropriate Medication was related with increasing age [OR=1.02 (95%CI: 1.00-1.05)], polypharmacy [OR=4.45 (95%CI: 3.12-6.36)], and be diagnosed with depression/anxiety [OR=2.18 (95%CI: 1.36-3.51)] and/or arthrosis [OR=1.64 (95%CI: 1.11-2.42)].
