After a Hospitalization, Older Adults Prescribed Potentially Inappropriate Medications May Face Health Risks

Journal of the American Geriatrics Society Research Summary

Potentially inappropriate medications (PIMs)” are treatments that sometimes pose risks that outweigh their benefits, particularly for people who are 65 or older. About 20 to 60 percent of older adults take medicines that may be potentially inappropriate. That can increase the risk for being hospitalized, needing to visit the emergency department, having poor quality of life, and/or experiencing a harmful reaction.

When older adults are hospitalized for medical reasons or for surgery, they often go home with prescriptions for treatments that may be different from those they were taking beforehand. These treatments may include PIMs. Until now, however, few studies have examined how PIMs affect older adults when prescribed at the time of their hospital discharge.

A team of researchers recently designed a study to learn more about this important issue. They examined information from medical and surgical patients to evaluate the association of PIMs (both the ones the patients had been taking earlier as well as those newly prescribed at their hospital discharge) with the risk of four outcomes. The outcomes were harmful drug problems, emergency department visits, readmission to the hospital, and death after hospital discharge. The study was published in the Journal of the American Geriatrics Society. Continue reading

New Study Suggests Cautions About Antipsychotic Medications for Hospitalized Older Adults

Journal of the American Geriatrics Society Research Summary

Delirium (sudden confusion or a rapid change in mental state) remains a serious challenge for our health care system. Delirium affects 15 to 26 percent of hospitalized older adults and can be particularly problematic because those experiencing the condition may interfere with medical care or directly harm themselves or others. Besides behavioral therapy and physical restraints, antipsychotic medicines are among the few therapeutic options healthcare providers can use to ease delirium and protect patients and caregivers—but antipsychotics also come with risks of their own.

To learn more about the effect of antipsychotic medicines on older hospitalized patients, a research team created a study published in the Journal of the American Geriatrics Society. This study included information from hospitalized patients at a large academic medical center in Boston.

The researchers looked specifically at death or non-fatal cardiopulmonary arrest (heart attack) during hospitalization.

The researchers learned that adults taking “first-generation” or “typical” antipsychotic medications (medicines first developed around the 1950s) were significantly more likely to experience death or cardiopulmonary arrest, compared to people who did not take those drugs. Taking “atypical” or “second-generation” antipsychotics (so named because they were developed later) raised the risk for death or cardiopulmonary arrest only for people aged 65 or older.

In the past, other studies have suggested that typical antipsychotic medications could cause sudden death, and that atypical antipsychotics could raise peoples’ risks for falls, pneumonia and death. What’s more, another large study also suggested that both types of antipsychotic medicines posed a risk for fatal heart attacks.

Despite these known risks, atypical antipsychotics are often prescribed for people in the hospital. One recent study of patients at Beth Israel Deaconess Medical Center in Boston found that antipsychotics were prescribed for nine percent of all adults who were hospitalized for non-psychiatric causes.  Another large recent study found that using antipsychotics to prevent or treat delirium did not lower the risk for death, did not lessen the severity of delirium or shorten its duration, and did not shorten the time people spent in the intensive care unit (ICU) or their hospital length of stay.

“Delirium is common in older hospitalized patients and difficult to treat, but antipsychotic medications should be used with caution regardless of age,” said the authors.

Geriatricians, Internists, and Cardiologists Surveyed About Deprescribing

Journal of the American Geriatrics Society Research Summary

También disponible en español – Ver abajo.

As you grow older, you’re more likely to develop health conditions that require taking multiple medications—some of which you may take for a long time. Many older people also take over-the-counter (or “OTC”) medications, vitamins, or supplements as part of routine care. As a result, older adults have a higher risk of overmedication, also known as “polypharmacy”—the medical term for taking four or more medications at the same time. Polypharmacy can increase your chances of unwanted reactions (also called “adverse drug reactions”) due to medications taken on their own or together.

To address this increasingly common problem, healthcare providers are focusing on how to reduce the number of medicines older adults are using through a practice called “deprescribing,” which is when health professionals work with patients to decide to stop the use of one or more medications for which the benefits no longer outweigh the potential harms.

Getting both patients and health professionals on board with deprescribing can be key to its success, however. In order to learn more about physicians’ attitudes and approaches to deprescribing medications for older adults, a team of researchers designed a survey. They published their investigation in the Journal of the American Geriatrics Society. Continue reading

Medications Used to Treat Atrial Fibrillation May Raise Risk of Falls and Fall-Related Injuries

Journal of the American Geriatrics Society Research Summary

For older adults, fainting and falls are serious health concerns. They can lead to injury, hospitalization, and other severe consequences. Having certain chronic conditions, as well as taking certain medications, can raise your risk of experiencing falls and fall-related injuries.

One condition that contributes to fainting and falls is atrial fibrillation. Atrial fibrillation occurs when the upper (atrial) part of your heart contracts rapidly and irregularly (fibrillates). Atrial fibrillation may be continuous or occasional and is the most common irregular heart rhythm in older adults. It occurs in three to five percent of people over age 65.

To prevent atrial fibrillation symptoms, health professionals may treat patients with medications to control their heart rate or rhythm. However, these medications can potentially raise the risk for falls and fainting, though the connection hasn’t studied significantly in the past.

To learn more, researchers in Denmark designed a study to learn more about the potential risk for falls and fainting among older adults taking medication for atrial fibrillation. Their study was published in the Journal of the American Geriatrics Society. Continue reading

High Blood Pressure Treatment and Nursing Home Residents

Journal of the American Geriatrics Society Research Summary

Although 27 percent of all older adults who live in nursing homes in this country have both high blood pressure and dementia, we don’t have enough research yet to inform healthcare providers about the best way to treat their high blood pressure.

Specifically, we don’t know when the benefits of taking medication to lower blood pressure outweigh the potential risks, especially in older adults who also have moderate to severe dementia and a poor prognosis (the medical term for the likely course of a disease). That’s because clinical trials for high blood pressure treatments typically do not include older adults who have severe chronic illnesses or disabilities.

 A team of researchers designed a study to learn more about the best high blood pressure treatments for older adults who live in nursing homes. Their study was published in the Journal of the American Geriatrics Society.

The research team used information from Medicare records. The team identified 255,670 long-term nursing home residents in the United States during 2013 who had high blood pressure. Of these, nearly half had moderate or severe dementia-related difficulties with thinking and decision-making. Slightly more than half of them had no or only mild cognitive impairment. Continue reading
