Polypharmacy in elderly patients with falls

Background : Falls in elderly–a multifactorial syndrome. One of the modifiable factors is polypharmacy. STOPP/START criteria are used for correction of polypharmacy in geriatrics. Aim : Assessment of the prevalence of polypharmacy, analysis and correction of pharmacotherapy using STOPP/START criteria in patients with falls. Materials and methods : The study included 655 patients hospitalized in the geriatric department over 60 years of age, who were divided into two groups. Group 1 (n=332, 50.7%)–patients with 1 or more falls, group 2 (n=323,49.3%)–patients without falls. The analysis of the received therapy before hospitalization was performed. After that, based on the indications, contraindications and STOPP/START criteria, drug therapy was corrected in patients with falls. Results : Patients of group 1 took 4.5±2.18 drugs, group 2–4.3±2.6. Polypharmacy was diagnosed in 150 (45.2%) patients with falls and in 122 (37.8%) patients without falls. Patients with falls were more likely to receive sleeping pills, NSAIDs. Univariate analysis showed that falls were associated with NSAIDs (OR 2.15, 95% CI 1.38–3.35, p=0.001) and sleeping pills (OR 2.03, 95% CI 1.02–4.02, p=0.047). An audit and correction of therapy was performed: in 108 (32.5%) patients the number of prescribed drugs was reduced. Patients with falls were prescribed statins, antidementia drugs, anticonvulsants and antidepressants as components of therapy for chronic pain syndrome, chondroitin sulfate and glucosamine sulfate for the treatment of osteoarthritis, calcium and antiresorbtive therapy, antianemic drugs, vitamin D. Antiplatelet agents, digoxin, sleeping pills and NSAIDs were less frequently prescribed. STOPP/START criteria and their frequency in patients with falls were analyzed. 141 cases of potentially non-recommended but prescribed medications were identified. STOPP criteria were for the administration of NSAIDs (n=53, 37.6%) and acetylsalicylic acid (n=62, 44%). There were 458 cases of potentially recommended but not prescribed medications. The most common START criteria were not for the administration of vitamin D and statins. Conclusion . Half of elderly patients with falls have polypharmacy. These patients are more likely to take sleeping pills and NSAIDs. STOPP criteria most often concerned the appointment of NSAIDs and acetylsalicylic acid, and the START criteria revealed the absence of the appointment of vitamin D and statins.
