How many medications does the average elderly patient take?

According to research published in the Journal of the American Medical Association (JAMA), more than 4 out of every 10 adults aged 65 or older used 5 or more prescription medications between 2017 and 2020, representing a near doubling in prevalence over 20 years. This growing trend directly relates to the question of how many medications does the average elderly patient take?

Quick Summary

The average older adult takes multiple daily medications, with the number escalating significantly among those managing multiple chronic conditions, a practice known as polypharmacy. The average number is often reported as four or more daily medications, and a significant portion of seniors takes eight or more.

Key Points

• Prevalence of Polypharmacy: Studies show that a significant portion of older adults, over 40%, take five or more daily medications, a practice known as polypharmacy.

• Key Risks of Multiple Medications: Excessive medication use increases the risk of adverse drug reactions, drug-drug interactions, falls, and cognitive impairment.

• Importance of Medication Reviews: Annual reviews with a healthcare provider or senior care pharmacist are essential to identify and reduce unnecessary or potentially harmful medications.

• Deprescribing as a Solution: Deprescribing, the process of discontinuing or reducing unnecessary medications, is a proactive strategy to reduce polypharmacy and improve outcomes.

• Role of Caregivers: Caregivers play a crucial role in medication management by helping with organization, reminders, and communication with healthcare teams.

• Minimizing Medication Errors During Transitions: The formal process of medication reconciliation is critical during hospital discharge to prevent errors and ensure accurate medication lists.

Understanding the statistics behind elderly medication use

Recent studies indicate a notable increase in medication use among older adults over the past two decades. While one report from Age Wave and JAHF found the average older adult takes four daily medications, other sources highlight even higher numbers, particularly when factoring in polypharmacy. Polypharmacy is clinically defined as the regular use of five or more medications, including prescription drugs, over-the-counter (OTC) medicines, and supplements. This is a critical issue as the number of prescriptions per patient often rises with age to manage multiple chronic conditions.

The alarming rise of polypharmacy

One study analyzed data from 1999–2000 through 2017–2018 and found that the prevalence of polypharmacy in adults 65 years and older increased from 23.5% to 44.1%. The reasons for this increase are multifaceted and include a rise in the number of people living with multiple chronic diseases, such as diabetes and heart disease. The consequence is a medication regimen that grows in complexity, heightening the risk of adverse drug events and dangerous drug-drug interactions.

Factors contributing to higher medication counts

Several factors explain why seniors accumulate more medications over time:

• Multimorbidity: As people age, they often develop several chronic conditions, each requiring its own treatment, leading to an expanded medication list.
• Prescribing cascades: This occurs when a new medication is prescribed to treat a side effect of another drug, mistaking the side effect for a new medical condition. This can lead to a domino effect of increasing medication use.
• Lack of periodic review: Without regular, thorough medication reviews, seniors may continue taking prescriptions that are no longer necessary, sometimes even for conditions that have resolved.
• Multiple prescribers: Seeing multiple specialists for different health issues can result in uncoordinated care, leading to duplicate prescriptions or drugs that interact negatively with each other.
• Including OTC and supplements: Many seniors add over-the-counter medications, herbal remedies, and dietary supplements to their regimen without informing their doctors, which can lead to harmful interactions.

The real risks of excessive medication use

Taking many medications, especially when not coordinated, poses significant health risks for older adults. The physiological changes that come with aging—including shifts in metabolism and body composition—can alter how drugs are processed, increasing susceptibility to adverse effects.

1. Adverse drug events (ADRs): The risk of adverse events rises with each additional medication. These can range from minor discomforts to severe, life-threatening complications.
2. Increased falls and fractures: Many medications, particularly those affecting the central nervous system like sedatives and some antidepressants, can cause dizziness and confusion, leading to falls.
3. Cognitive impairment: Polypharmacy is linked to reduced alertness, confusion, and other cognitive issues. Certain medications, especially those with anticholinergic properties, can impair cognitive function.
4. Hospitalizations: Adverse drug events and drug-related problems are major drivers of hospital admissions among the elderly, increasing healthcare costs and negatively impacting quality of life.
5. Medication non-adherence: Complex medication schedules can be confusing and overwhelming. As a result, seniors may miss doses, take them incorrectly, or stop taking them altogether.

Proactive medication management for seniors

Fortunately, there are effective strategies for managing and mitigating the risks associated with polypharmacy. This involves a collaborative effort between the patient, caregivers, and the healthcare team.

Annual medication reviews: This is a crucial step for all seniors, especially those on multiple medications. An annual review with a doctor or pharmacist can help identify unnecessary drugs, check for duplicates, and ensure dosages are appropriate. A senior care pharmacist, who specializes in the needs of older adults, can be a valuable resource.

Deprescribing: This is the process of reducing or stopping medications that are no longer beneficial or may be causing harm. It involves carefully evaluating the risks and benefits of each medication and discontinuing those that are no longer necessary, often through a gradual tapering process.

Simplified regimens: Doctors and pharmacists can work together to simplify medication schedules by consolidating doses, using combination pills, or implementing once-daily options to make adherence easier.

Tools for organization: Using tools such as weekly pill organizers or automated dispensers can help ensure the correct dose is taken at the right time. Smartphone apps are also available to provide reminders.

Improved communication: Open, honest communication with all healthcare providers is essential. Seniors and their caregivers should bring a complete, up-to-date list of all medications, including OTCs and supplements, to every appointment.

The importance of medication reconciliation

Medication reconciliation is a formal process designed to prevent medication errors by comparing a patient's current medication list to any new medication orders. This is especially vital during care transitions, such as hospital admission or discharge, where up to 45% of older patients may experience medication discrepancies. Nurses, pharmacists, and other healthcare professionals play key roles in this process by developing accurate medication histories and ensuring a seamless transition of care.

The role of the caregiver

For many seniors, family members and caregivers are instrumental in medication management. They can assist with organization, provide reminders, and attend doctor's appointments to help with communication. Given the complexities, caregiver education is a vital component of successful medication management for older adults.
