Potentially inappropriate medications and anticholinergic and sedative burden in older community-dwelling patients with advanced chronic kidney disease

Objective. Regarding older patients, multiple chronic conditions lead to the intake of multiple medications, involving a higher risk of adverse drug events. In older patients with advanced chronic kidney disease, the medication exposure was poorly explored. The aim of this study was to describe the use of potentially inappropriate medications and medications with anticholinergic and sedative properties in older community-dwelling patients with advanced chronic kidney disease. Methods. An observational study was conducted in a geriatric day-care unit. All patients aged over 65 years with advanced chronic kidney disease, defined by estimated glomerular filtration rate < 20 mL/min/1.73 m(2) or estimated glomerular filtration rate > 20 mL/min/1.73 m(2) with rapid progression, and referred by nephrologist for pretransplant comprehensive geriatric assessment, were included in the study. Potentially inappropriate medications were identified using the EU(7)-PIM list, and he anticholinergic and sedative drug exposure was measured using the Drug Burden Index. Results. Overall, 139 patients were included in the study (mean age 74.4 +/- 3.3 years, 32.4% females, 61.9% on dialysis). Potentially inappropriate medications were used by 74.1% (103/139) of patients and were mainly represented by proton pump inhibitors, alpha-1-blockers and central anti-hypertensive drugs. Regarding anticholinergic and / or sedative medications, 79.9% (111/139) of older patients were exposed. Conclusion. In older community-dwelling patients with advanced chronic kidney disease, the prevalence of potentially inappropriate medication exposure and anticholinergic and sedative exposure was high. Interventions focusing on deprescription of these inappropriate medications should be conducted in this specific population.
