Is Your Hospital Stay Making You Healthier? How Pharmacists are Key to Elderly Care
"Uncover how hospital pharmacists are revolutionizing elderly inpatient care, reducing medication risks, and improving health outcomes."
As global fertility rates decline and life expectancy increases, the world's elderly population is rapidly growing. This demographic shift brings advancements in medical and pharmaceutical technologies, leading to greater use of healthcare services and medications for chronic and degenerative diseases. By 2025, Brazil is projected to have the sixth-largest elderly population globally, highlighting the urgent need for optimized healthcare strategies.
However, the natural physiological changes that come with aging can significantly impact how medications are processed by the body. This can result in exaggerated or inappropriate responses to medication, or even a complete lack of therapeutic benefit. This has raised widespread concern about the appropriate use of medication in older patients, making it a critical area of focus for healthcare professionals.
One of the key strategies for improving medication use in the elderly is to focus on reducing adverse drug events (ADEs), which can range from unnecessary drug use and inappropriate drug choices to a lack of long-term therapy reassessment. To tackle this, many guides and resources have been developed to help clinicians choose the best therapeutic options. Among these, the Beers List is the most frequently used tool for identifying potentially inappropriate medications for older adults.
An Aging World and the Meaning of Eldercare
The number of elderly people worldwide began to surge in the second half of the 20th century; before then, five percent or less of the population in developed countries was over 65. Eldercare addresses older adults' daily needs through services such as assisted living, adult daycare, long-term care, nursing homes, hospice care, and home care. The term "elderly" is not universally welcomed: one study reported that 57% of adults over 65 disliked being called elderly. These demographic and language considerations help explain why hospital and pharmacy care for older adults must be both comprehensive and respectful.
A Coordinated but Individualized Approach
Care for older hospital patients generally aims to coordinate medication management with broader clinical and daily-living needs. In practice, the appropriate approach may vary according to a person's health status, support network, and care setting. Standard procedures can provide useful structure, but they may not address every patient's preferences or circumstances. Pharmacists therefore have an important opportunity to identify medication-related concerns while working alongside the wider care team.
The Evolving Role of Elderly Care
Elderly care has developed into a broad field rather than a single form of service. Its modern framework may include institutional, community, hospice, and home-based support. The role of pharmacists in this history is best understood as part of a wider movement toward coordinated care for older adults. Specific milestones vary by health system, so broad historical claims should be made cautiously.
The Pharmacist's Role: Reducing Medication Risks in Hospitals
Adverse drug events are a significant concern in healthcare, particularly among hospitalized patients. According to research, 1% of all hospital admissions are caused by drug-drug interactions (DDIs), accounting for 16% of all hospital admissions due to adverse drug reactions (ADRs). In the United States, these ADRs lead to increased hospital costs, estimated at around $4,700 per admission, totaling $2 billion annually.
- Study Design: A prospective cohort study was conducted, utilizing medical records of patients admitted to an internal medicine ward.
- Data Collection: All admissions and prescriptions were monitored from March to August 2006.
- Identification of Risks: Micromedex® DrugReax® and Beers Criteria 2015 were used to identify pDDI, major pDDI, and PIMs.
- Analysis: Admission and discharge prescriptions were compared to assess changes in medication profiles.
Evidence-Informed Medication Care
Recent discussion of elderly hospital care commonly emphasizes the need to review medications in the context of the whole patient. Pharmacists can contribute by examining treatment regimens, clarifying potential problems, and supporting communication across transitions of care. The strength of available evidence may differ across interventions and settings. Accordingly, medication services should be evaluated alongside patient goals, clinical outcomes, and continuity of care.
Limits of Hospital-Based Support
Pharmacist involvement does not eliminate every risk associated with hospitalization or complex medication use. Discharge misunderstandings, fragmented communication, changing prescriptions, and limited follow-up can still undermine otherwise careful plans. Benefits may also depend on staffing, coordination, and whether patients and caregivers can participate in decisions. A balanced assessment should therefore recognize both the value of pharmacy expertise and the system conditions that can limit its effect.
Comparing Care Settings
Medication needs can look different in hospitals, residential facilities, outpatient services, and the home. Hospital care may offer concentrated clinical expertise, while longer-term settings may provide more sustained observation of daily medication use. No single setting is automatically best for every older adult. Comparisons should account for safety, continuity, patient preferences, caregiver support, and access to qualified professionals.
The Impact of Clinical Pharmacists on Patient Safety
The study concludes that admission to a hospital ward with a clinical pharmacist is associated with a significant reduction in the number of elderly inpatients exposed to polypharmacy, pDDIs, major pDDIs, and PIMs. This highlights the crucial role of clinical pharmacists in improving medication safety and ensuring better health outcomes for elderly patients. The presence of a clinical pharmacist provides an invaluable opportunity to optimize medication regimens, reduce potential risks, and enhance the overall quality of care for older adults during their hospital stay.
Pharmacists as Care Coordinators
The central lesson is that pharmacists are most valuable when medication decisions are connected to the older person's broader care plan. Their contribution can include identifying risks, explaining treatment changes, and helping teams maintain consistency during transitions. This role complements rather than replaces physicians, nurses, caregivers, and patients. Effective elderly care therefore depends on collaboration and attention to the individual's goals.
Building More Continuous Care
Future progress will likely depend on linking hospital pharmacy services more closely with outpatient, residential, and home care. Better information sharing could help teams identify medication changes and unresolved concerns earlier. New approaches should be assessed not only for efficiency but also for safety, accessibility, and patient understanding. Research will need to clarify which models work best for different older populations and care environments.
Care Within an Aging System
The growth of the older population places pressure on health and social-care systems to support complex needs across multiple settings. Eldercare extends beyond hospitals to assisted living, adult daycare, long-term care, nursing homes, hospice, and home care. Systemic challenges can include workforce capacity, fragmented services, and unequal access to expertise. Addressing them requires coordination between clinical care, daily support, families, and community resources.
Respectful, Person-Centered Care
Medication safety is also a human issue involving trust, communication, independence, and dignity. Older adults may have preferences about how they are described and how their care is organized; one study reported that 57% of adults over 65 disliked being called elderly. Pharmacists can make care more understandable by listening carefully and explaining treatment in practical terms. The goal is not simply to manage prescriptions, but to help people participate meaningfully in decisions about their health.
