Report Sounds Alarm on Medication Overload Among Older Americans

Thousands end up in emergency departments every year due to the problem

Experts on aging are sounding the alarm about another U.S. drug crisis: Too many older adults taking too many medications.

This trend is leading to a surge in adverse drug events (ADE) over the past two decades. The rate of emergency department visits by older adults for adverse drug events doubled between 2006 and 2014. That’s a problem as serious as the opioid crisis, but whose scope appears to remain virtually invisible to families, patients, policymakers and many clinicians, according to a recent report by the Lown Institute, a nonprofit think tank in Brookline, Mass.

Medication overload is an unseen epidemic that could result in 74 million outpatient visits, 4.6 million hospitalizations and 150,000 premature deaths among older Americans, costing our health system $62 billion, according to report author Shannon Brownlee, a Lown senior vice president.

“No health care professional group, public organization or government agency to date has formally assumed responsibility for addressing this national problem.”

The problem is systemic, said Brownlee, during an April 2 telebriefing. “No health care professional group, public organization or government agency to date has formally assumed responsibility for addressing this national problem.”

Over the past decade, older adults sought treatment for a serious drug event 35 million times and were admitted to the hospital about 2 million times, said Brownlee. The rate of emergency department visits for ADEs jumped from 5 to 10 per 1,000 older adults (194,000 to 450,000 emergency department visits over 10 years). It has to do with the corresponding rise in polypharmacy, a situation that has reached “epic proportions,” she added.

Too Many Meds

More than 4 in 10 older adults take five or more prescription medications daily — a 200% increase in the past 20 years. Data shows that 20% of older adults take 10 or more prescriptions in a year, as Austin Frakt wrote in this New York Times article. The risk of an adverse drug event increases by 7% to 10% with each medication.

Three classes of drugs contribute to 60% of emergency department visits for ADEs among older adults, according to the report: Blood thinners, such as warfarin (sold under brand names such as Coumadin and Jantoven), which may lead to severe bleeding; diabetes medications such as insulin or gliclazide (sold under the brand name Diamicron, among others), which can cause low sugar, increasing risk of falls or confusion and opioids, which can cause sedation, falls or cognitive impairment.

The report says four other types of drugs increase the potential for harmful side effects: Sedative hypnotics, such as anti-anxiety medications; blood pressure medications; antipsychotics and many commonly used over-the-counter drugs, including antihistamines and bladder medications.

A Culture and System that Leads to Overprescribing

The report looks at how the culture of medicine and a fragmented system of care can drive overprescribing. Medication overload isn’t new, but seems to be getting worse, said James McCormack, a pharmacist and professor in the pharmaceutical sciences department of the University of British Columbia.

“It is often far easier to prescribe medications than it is to reduce dosages or deprescribe,” McCormack said. “We strive to give the right medication in the right dose, at the right time, but the U.S. health care system isn’t structured properly to achieve that goal.”

Patients often become confused or overwhelmed when trying to track numerous medications, including where, when and how to take them and what they’re for, the Lown report said. Managing this “pill burden” can make compliance difficult, despite the best efforts of pharmacists, family caregivers or providers.

Patients often see multiple specialists who prescribe multiple medications, leading to an ADE jigsaw puzzle, said Dr. James Rudolph, a professor of medicine and health policy at Brown University and the director of the Center for Innovation in Geriatric Services at the Veterans Administration’s Providence, R.I., facility.

“So what happens is that there’s this prescription cascade,” Rudolph said. A patient then returns to the primary care provider with symptoms like dizziness, leading perhaps to yet another medication to address that. Despite a hierarchy in medicine which makes primary care practitioners reluctant to question medications prescribed by specialists, “we should perhaps step back and ask if symptoms are related to another medication,” Rudolph said.

Solutions to Medication Overload

The primary care provider and specialist should work together to address polypharmacy and ADEs, Rudolph said. “It’s also a good time to involve the pharmacist, since a lot of medications need time to taper off.”

He suggests that patients or family caregivers bring all of the information or pill bottles to the primary care provider and ask for a medication checkup. A key goal is to determine whether all the medications are really needed.

Make the provider aware there’s a concern about all of these medications and start that conversation, McCormick said. It can sometimes take months to unravel which prescription is causing a problem.

The cost burden is another issue for many patients who take multiple medications, the Lown report noted. In a 2015 survey, more than 40% of adults over 50 expressed concerned about affording medications due to high out-of-pocket costs. This can lead to non-adherence or pill rationing that can bring additional problems.

“These are critical issues, and we have to ask ourselves what’s taking so long,” said Terry Fulmer, president of the John A. Hartford Foundation (a funder of Next Avenue). “This report makes it clear we need to get on this; we need to be thinking about the high-risk medications that we already know are so deleterious to older people.”
