Cognitive and functional trajectories in geriatric outpatients after a pharmacologic multidisciplinary intervention:...

Polypharmacy is a common condition among older adults and is associated with adverse drug reactions and health outcomes, including falls, functional and cognitive impairment, and frailty.

A prospective observational study will be conducted on older adults with polypharmacy. The aim is to assess the impact of a specialized outpatient clinic focused on pharmacotherapy optimization recently integrated into daily clinical practice in a Spanish public tertiary teaching hospital on patients' functional and cognitive abilities. Patients who attend a first consultation and meet inclusion criteria (≥75 years old, have a life expectancy≥3 months, and polypharmacy (≥5 prescribed medications) will be invited to participate in the study, until reach a calculated sample size of 104 participants. Patients will be excluded if they are enrolled in a clinical trial related to medication or in the event of a no-show or cancellation of the appointment at the first visit. Participants will receive usual care: a first consultation including multidisciplinary pharmacological optimization in the context of a CGA and subsequent face-to-face and/or telephone follow-up (∼3 and ∼6 months). The primary endpoint will be the functional (Barthel index) and cognitive change in capacities (IPCR - Índice de Incapacidad psíquica de la Cruz Roja). Secondary endpoints include medication changes, changes in patients' quality of life, rate of falling, and use of healthcare resources.

We expect that the close collaboration between professionals from different disciplines working together will be an effective strategy to improve the functional and cognitive abilities of older adults.
