The Role of the Pharmacist in Optimizing Pharmacotherapy in Older People

Abstract

Prescription of medicines is a fundamental component of the care of older people, but evidence suggests that pharmacotherapy in this population is often inappropriate. Pharmacists have been involved in different approaches for the optimization of prescribing and rational medication use in older people. This article describes the different models of care in which pharmacists are involved in the optimization of pharmacotherapy in older people, and reviews the impact of these approaches on both process and outcome measures. The provision of pharmaceutical care, medication reviews and educational interventions by pharmacists in the nursing home, ambulatory and acute care settings are discussed. We selected systematic reviews, reviews and original studies, and for the latter, we focused more specifically on European publications published between 2001 and 2011. From the literature reviewed, it is clear that when pharmacists play a proactive role in performing medication reviews and in the active education of other healthcare professionals, pharmacotherapy for older patients is improved. However, the evidence of the impact of pharmacists' interventions on health outcomes, quality of life or cost effectiveness of care is mixed. Better results have been reported when pharmacists are skilled and work in the context of a multidisciplinary team. Opportunities remain for multicentre, European-based, pharmacist-intervention trials in all settings, to determine the effectiveness and economic benefit of pharmacist involvement in the optimization of pharmacotherapy in older people.

“…When pharmacists play a proactive role in performing medication reviews and in the active education of other healthcare professionals, pharmacotherapy for older patients is improved [10]. However, the evidence of the impact of pharmacists' interventions on health outcomes, quality of life, or cost-effectiveness of care is mixed [11]. Few studies of pharmaceutical care programs for older adults have undertaken a rigorous economic evaluation, and a more standardized approach to data collection is required [12].…”

An International Perspective on Pharmacy Student Selection Policies and Processes

“…4 Notwithstanding the important contribution of other health professionals, pharmacists, with their unique focus on all aspects of medicines, are ideally placed to provide medicines optimization in both hospital and community settings; indeed, this is increasingly recognized as their societal purpose. 5 The drivers of new pharmacist roles include the increasing complexity and costs of pharmacotherapy, the growing burden of chronic illness, and shortages of health professionals in many countries. In moving from the traditional distributive functions of dispensing and selling medications to more clinical and public health roles, pharmacists will require new or enhanced skills in areas such as consultation, diagnosis, physical assessment, clinical decision-making, prescribing, communication, and moral reasoning.…”
