A multifactorial intervention to lower potentially inappropriate medication use in older adults in Argentina.

BACKGROUND: Adverse drug reactions are a common cause of potentially avoidable harm, particularly in older adults. AIMS: To evaluate the feasibility and efficacy of a pilot multifactorial intervention to reduce potentially inappropriate medication (PIM) use in older adults. METHODS: We conducted a phase 2, feasibility, open-label study in the ambulatory setting of an integrated healthcare network in Buenos Aires, Argentina. We recruited primary care physicians (PCPs) and measured PIM use in a sample of their patients (65 years or older). Educational workshops for PCPs were organized with the involvement of clinician champions. Practical deprescribing algorithms were designed based on Beers criteria. Automatic email alerts based on specific PIMs recorded in each patient's electronic health record were used as a reminder tool. PCPs were responsible for deprescribing decisions. We randomly sampled 879 patients taking PIMs from eight of the most commonly used drug classes at our institution and compared basal (6 months prior to the intervention) and final (12 months after) prevalence of PIM use using a test of proportions. RESULTS: There was a significant reduction (p < 0.05) in all drug classes evaluated. Non-Steroidal Anti-Inflammatory Drugs (basal prevalence 5.92%; final 1.59%); benzodiazepines (10.13%; 6.94%); histamine antagonists (7.74%; 3.07%); opioids (2.16%; 1.25%); tricyclic antidepressants (8.08%; 4.10%); muscle relaxants (7.74%; 3.41%), anti-hypertensives (3.53%; 1.82%) and oxybutynin (2.96%; 1.82%). The absolute reduction in the overall prevalence was 8.5 percentage points (relative reduction of 51.4%). CONCLUSION: This multifactorial intervention is feasible and effective in reducing the use of potentially inappropriate medication in all drug classes evaluated.

[Study of the performance of complex activities of daily living in a population of patients with mild cognitive impairment. Mild functional impairment: A new clinical entity?] / Estudio del desempeño de las actividades complejas de la vida diaria en una población de pacientes con Deterioro Cognitivo Leve. Deterioro Funcional Leve: ¿una nueva entidad clínica?

Several papers describe functional changes in the aging population, and its relevance in the early cognitive impairment detection. Alterations in instrumental activities would constitute a diagnostic marker of MCI and predict the progression to Dementia. In order to count on a tool to evaluate the performance in the use of new technologies we have designed a new protocol, Complex Functional Study (CFS), that quantifies performance and functional changes Related to previous states. OBJECTIVES: To compare CFS scores in patients with MCI with a control group without cognitive impairment (CD) and verify their diagnostic performance to detect complex function alterations in reference too the functional scales, Instrumental Activities of Daily Living (AVDI) and Disability Assessment for Dementia (DAD). METHODS: Patients with MCI and controls were included. All subjects were evaluated with a neurocognitive battery, and functional scales (EFE).STATA software version 14.2 was used for data analysis. RESULTS: 269 recruited patients older than 65 years old, 173 with diagnosis of MCI and 96 controls. The MCI patients obtained significantly higher EFE scores tan subjects without DC (p < 0,001).The EFE presented a greater sensitivity to detect the functional alteration (EFE 81.5%, AVDI 25.9%, DAD 18.5%). CONCLUSIONS: The EFE is an instrument of optimal clinical value, with good sensitivity to identify the alteration of the complex activities of daily life in patients with MCI. The results allow to characterize a profile compatible with Light Functional Impairment.
