Latest Evidence and Guidance on Medication Adherence Among Elderly Patients and Caregivers

Medication adherence in elderly patients is a multifactorial challenge influenced by patient characteristics, cognitive and physical impairments, caregiver involvement, regimen complexity, socioeconomic factors, and health system support. Addressing adherence requires a comprehensive, individualized, and multidisciplinary approach that actively involves both patients and their caregivers, particularly during vulnerable periods such as transitions of care.

Adherence rates among older adults vary widely, with suboptimal adherence contributing to negative clinical outcomes, increased hospitalizations, and higher healthcare costs. Key barriers include cognitive decline, especially memory and executive dysfunction, multimorbidity and polypharmacy, psychological factors (e.g., anxiety, depression), cultural beliefs, social isolation, and financial constraints. The presence of cognitive impairment notably diminishes the ability of elderly individuals to manage medications independently, substantially increasing the need for caregiver support to ensure treatment continuity and safety Smith et al. 2017Cardona-Arango et al. 2026Mehany et al. 2026 NICE CG76.

Caregivers play a central role in maintaining medication adherence, especially for patients with cognitive impairments such as dementia, by providing supervision, aid in administration, and error prevention. Effective caregiver involvement is linked to improved adherence rates and reductions in adverse events Wagle et al. 2018Mehany et al. 2026 NICE CG76.

System-level challenges, including fragmented care, inconsistent medication communication during transitions of care, poor access to medicines, and inadequate health literacy, contribute to poor adherence and medication errors. Transitions of care particularly amplify risks due to medication regimen changes, insufficient patient and caregiver education, and breakdowns in information transfer among healthcare providers. Strategies that improve communication, promote shared decision-making, and provide tailored education support safer medication use during these periods Zou et al. 2025 NICE CG76.

Interventions to improve adherence must be multilevel, combining personalized education, simplification of medication regimens (e.g., single-pill combinations), digital health tools (automated reminders, mobile apps, telepharmacy), and pharmacological management. Digital interventions have demonstrated benefit in improving adherence and clinical outcomes; however, challenges such as digital literacy and accessibility remain. Integration of artificial intelligence and machine learning offers promise in predicting non-adherence and optimizing interventions but requires further validation Mehany et al. 2026Cardona-Arango et al. 2026 NICE CG76.

Pharmacist-led medication management and home healthcare nurse involvement have been associated with improved adherence rates. Programs that provide continuity of care, assertive communication, and medication reconciliation play critical roles in overcoming practical barriers faced by elderly patients Cardona-Arango et al. 2026Mehany et al. 2026 NICE CG76.

Psychological support addressing anxiety, depression, and medication beliefs, as well as culturally sensitive interventions, enhance engagement and motivation for adherence. Health professionals are encouraged to adopt patient- and family-centered approaches that empower elderly patients and caregivers, including facilitating active participation in medication decisions, using plain language, and ensuring follow-up support Cardona-Arango et al. 2026Zou et al. 2025 NICE CG76.

Given the complexity and diversity of barriers, a single intervention is insufficient; hence, sustained, coordinated strategies involving multidisciplinary teams, caregivers, and system reforms are necessary to maintain adherence over time. Public health policies should support continuity of care, accessibility of medicines, and caregiver empowerment to reduce preventable medication-related harms and improve quality of life for the aging population Cardona-Arango et al. 2026Mehany et al. 2026Zou et al. 2025 NICE CG76.
