Polypharmacy, which is defined as being on 5 or more medicines, is a major concern for healthcare providers, particularly in the older population with multimorbidity. Multimorbidity refers to the coexistence of two or more chronic conditions in an individual. With the aging population and the increasing prevalence of chronic diseases, the use of multiple medications has become common practice in managing the complex health needs of this population. However, polypharmacy poses risks in terms of drug-drug interactions, adverse drug reactions, and medication non-adherence. In this paper, we will explore the issues surrounding polypharmacy and discuss potential strategies to mitigate its negative effects.
The use of multiple medicines in the older population is inevitable due to the high prevalence of chronic diseases such as hypertension, diabetes, heart disease, and arthritis. Each condition often requires the use of one or more medications to achieve optimal management. Moreover, age-related physiological changes and comorbidities can affect the pharmacokinetics and pharmacodynamics of medications, making older adults more susceptible to drug-related problems. Consequently, healthcare providers have the challenging task of prescribing and managing medications to balance the benefits and risks in this vulnerable population.
Polypharmacy has been associated with several negative outcomes, including an increased risk of drug-drug interactions. As the number of medications increases, so does the likelihood of an interaction occurring. Drug-drug interactions can result in altered drug metabolism, pharmacokinetics, and pharmacodynamics, potentially leading to adverse effects or reduced therapeutic efficacy. Such interactions can be predictable, such as when two medications with similar mechanisms of action are combined, or unpredictable, such as when a medication interacts with a specific genetic or physiological factor in an individual. Additionally, the risk of adverse drug reactions also increases with polypharmacy. Older adults are more likely to experience adverse drug reactions due to age-related changes in drug metabolism, increased sensitivity to medications, and the presence of comorbidities.
Another concern associated with polypharmacy is medication non-adherence. Managing multiple medications and their associated schedules can be challenging for older adults, especially those with cognitive impairments or limited functional abilities. Non-adherence can result in poor disease control, increased healthcare utilization, and higher healthcare costs. It is essential for healthcare providers to consider patients’ abilities and preferences when prescribing multiple medications to promote adherence and optimize health outcomes.
To address the issues surrounding polypharmacy, a comprehensive approach is needed. This approach should involve medication reconciliation, patient education, shared decision-making, and regular medication reviews. Medication reconciliation is a process of comparing the medications a patient is taking to those prescribed, with the goal of identifying and resolving discrepancies. It ensures that patients receive the most accurate and appropriate medications, minimizing the potential for drug-drug interactions. Patient education plays a crucial role in promoting medication adherence and self-management. Healthcare providers should provide clear and understandable information about the purpose of each medication, expected benefits and potential side effects, and instructions on how to take the medication correctly.
Shared decision-making is a collaborative process between patients and healthcare providers, in which both parties discuss the available treatment options, potential benefits and risks, and consider the patient’s values and preferences. In the context of polypharmacy, shared decision-making allows patients to actively participate in decisions regarding their medication regimen. This can help align treatment goals with patients’ preferences and enhance medication adherence.
Regular medication reviews are essential to identify opportunities to deprescribe unnecessary medications and reduce polypharmacy. A systematic review of medications can help identify medications that may no longer be necessary or may be causing more harm than benefit. Healthcare providers should consider factors such as the patient’s goals of care, life expectancy, functional status, and overall burden of medications when conducting medication reviews. Deprescribing, the process of safely reducing or stopping medications, should be done in collaboration with patients, considering their individual circumstances and preferences.
In conclusion, polypharmacy is a major concern in the older population with multimorbidity. The use of multiple medications in this population is necessary but poses risks in terms of drug-drug interactions, adverse drug reactions, and medication non-adherence. Healthcare providers should adopt a comprehensive approach to address these issues, including medication reconciliation, patient education, shared decision-making, and regular medication reviews. By optimizing medication management, healthcare providers can improve patient outcomes and reduce the negative consequences associated with polypharmacy.
