Polypharmacy and slow metabolism of drugs create a high risk among older adults for substance use disorder, raising the odds of intentional and unintentional overdoses. However, screening, assessment, and treatment for substance use disorder occurs less often in younger adults.
Rates of overdose from opioids increased the most among people aged 65 years and older from 2021 to 2022, compared with among younger age groups. Meanwhile, recent data show less than half older adults with opioid use disorder (OUD) receive care for the condition.
“Nobody is immune to developing some kind of use disorder, so don’t just assume that because someone’s 80 years old that there’s no way that they have a problem,” said Sara Meyer, PharmD, a medication safety pharmacist at Novant Health in Winston-Salem, North Carolina. “You never know who’s going to potentially have an issue.”
in an effort to reduce addiction and overdoses.
Older Adults Have Unique Needs
A major challenge of treating older adults is their high incidence of chronic pain and multiple complex chronic conditions. As a result, some of the nonopioid medications clinicians might otherwise prescribe, like nonsteroidal anti-inflammatory drugs, cannot be used, according to Caroline Goldzweig, MD, chief medical officer of the Cedars-Sinai Medical Network in Los Angeles, California.
“Before you know it, the only thing left is an opiate, so you can sometimes be between a rock and a hard place,” she said.
But for adults older than 65 years, opioids can carry problematic side effects, including sedation, cognitive impairment, falls, and fractures.
With those factors in mind, part of a yearly checkup or wellness visit should include time to discuss how a patient is managing their chronic pain, according to Timothy Anderson, MD, an assistant professor of medicine at the University of Pittsburgh, Pittsburgh, Pennsylvania, and codirector of the Prescribing Wisely Lab, a research collaboration between that institution and Beth Israel Deaconess Medical Center in Boston.
When considering a prescription for pain medication, Dr. Anderson said he evaluates the potential worst, best, and average outcomes for a patient. Nonopioid options should always be considered first-line treatment. Patients and physicians often struggle with balancing an option that meets a patient’s goals for pain relief but does not put them at a risk for adverse outcomes, he said.
Greater Risk
Older adults experience neurophysiologic effects different from younger people, said Benjamin Han, MD, a geriatrician and addiction medicine specialist at the University of California, San Diego.
Seniors also absorb, metabolize, and excrete drugs differently, sometimes affected by decreased production of gastric acid, lean body mass, and renal function. Coupled with complications of other chronic conditions or medications, diagnosing problematic opioid use or OUD can be one of the most challenging experiences in geriatrics, Dr. Han said.
As a result, OUD is often underdiagnosed in these patients, he said. Single-item screening tools like the TAPS and OWLS can be used to assess if the benefits of an opioid outweigh a patient’s risk for addiction.
Dr. Han finds medications like buprenorphine to be relatively safe and effective, along with nonpharmacologic interventions like physical therapy. He also advised clinicians to provide patients with opioid-overdose reversal agents.
“Naloxone is only used for reversing opioid withdrawal, but it is important to ensure that any patient at risk for an overdose, including being on chronic opioids, is provided naloxone and educated on preventing opioid overdoses,” he said.
Steroid injections and medications that target specific pathways, such as neuropathic pain, can be helpful in primary care for these older patients, according to Pooja Lagisetty, MD, an internal medicine physician at Michigan Medicine and a research scientist at VA Ann Arbor Health Care, Ann Arbor, Michigan.
She often recommends to her patients online programs that help them maintain strength and mobility, as well as low-impact exercises like tai chi, for pain management.
“This will ensure a much more balanced, patient-centered conversation with whatever decisions you and your patient come to,” Dr. Lagisetty said.
