Introduction Pharmacists are among the most available and frequently consulted healthcare providers supporting older adults. They can actively contribute to thorough geriatric assessments and interventions and are often included in geriatric teams across different care settings. Aim This narrative review aims to compile current knowledge and practical approaches related to pharmacists’ roles in caring for older adults. Methods We searched in three databases and followed the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines. Included studies were randomized clinical trials (RCTs) and systematic reviews, published between the years 2014 and 2024 in any language, reporting on the involvement of pharmacists in geriatric care, their interventions and results. Results From 306 identified different records, 32 studies were included in the final synthesis. The majority (22; 68.8%) were systematic reviews, ten were RCTs. The studies reported on the role of pharmacists in geriatric care in diverse settings including home, community, outpatient clinics, hospital, long-term care and residential facilities. While interventions were often multifaceted and complex, they more commonly comprised medication reviews and medication reconciliation. Positive outcomes resulting from pharmacists´ interventions were reported in 71.9% of the studies, mostly focused on medication appropriateness, deprescribing, medication safety and effectiveness. Conclusion Our narrative review highlights the growing evidence supporting the integration of pharmacists into geriatric care teams across diverse clinical settings. Despite heterogeneity among studies and limited high-certainty evidence, the findings underscore the potential of pharmacists to contribute meaningfully to person-centred, multidisciplinary care in this vulnerable population.
