Inappropriate prescribing: hazards and solutions

With population ageing, the number of older people is growing, which results in increasing number of people with multimorbidity and related polypharmacy. Polypharmacy in its turn leads to drug-related problems (DRPs) and potentially inappropriate prescribing (IP) in older people. In this commentary, susceptibility of older people to DRPs due to changes in pharmacokinetics and pharmacodynamics, plurality of prescribing physicians, inadequate consideration of patients’ characteristics, polypharmacy and its consequences such as prescribing cascades, drug interactions and potentially IP have been discussed respectively. Consecutively, identifying DRPs and optimizing of IP, including drug reconciliation, application of criteria for identifying and preventing IP, implementation of computer-based prescribing systems, and comprehensive geriatric assessment and management have been elaborated as well. One of the main challenges regarding appropriate and tailored prescribing in older people is to evaluate whether the expected benefits of pharmacotherapy are bigger than the risks in a population with multimorbidity, decreased tolerance to vulnerability and limited life expectancy. Comprehensive geriatric assessment enables informed prescribing decisions in the context of such variables. A challenge for future research is how to integrate important clinical information obtained by existing methods into a comprehensive and wide-reaching approach targeting all potential factors involved in causing DRPs. Good prescribing in late life accommodates the needs of older patients with multimorbidity. Individualized, interactive, multidisciplinary, and multifaceted approach to geriatric pharmacotherapy should be promoted and encouraged. How to optimize pharmacological prescription in complex older patients is a major legacy of geriatrics to contemporary medicine/medical practice.
