Should Nursing Home Residents Nearing the End of Life Continue Taking Statins?

Posted on by

Journal of the American Geriatrics Society Research Summary

Cardiovascular disease (also called heart disease) is one of the most common medical conditions older adults face. In nursing homes, almost half of all older adult residents have been diagnosed with problems affecting the heart and/or blood vessels.

In spite of this, we know very little about how effective a class of popular heart disease medications may be for those 75 and older. Known as statins, these medications are prescribed to reduce the amount of cholesterol in your blood. High blood levels of cholesterol can damage your heart’s blood vessels and lead to the formation of blood clots, which can cause stroke and heart attacks.

The reason we have a knowledge gap as to how well statins work in older adults is because early medical studies that examined statin therapy for heart disease prevention included few adults age 75 and older. More recent trials that did include older adults often found that statin therapy did not help prevent these individuals from developing heart disease.

Why? It’s possible that, as we age, our sensitivity to medications may change. For instance, myopathy (muscle pain and weakness) is a commonly reported side effect of statins. This side effect may have a heightened effect on older adults who are already frail, which could speed up physical decline.

A team of researchers conducted a study to learn more about statin use among older adults, especially those nearing the end of their lives. Their study stemmed from concern about unclear statin prescribing guidelines for people over age 75, and a lack of information on the medications’ uses in nursing homes. The study, published in the Journal of the American Geriatrics Society, evaluated statin use by people with life-limiting conditions across nearly all U.S. nursing homes. The researchers hoped to identify statin use among nursing home residents who were unlikely to benefit from treatment. Continue reading →

Should Diabetes Treatment Lessen for Older Adults Approaching the End of Life?

One in four people aged 65 or older has diabetes. The disease is the seventh leading cause of death in the United States and a major contributor to heart disease. Experts have recommended that the best way to slow the progression of diabetes—and help prevent its many complications—is to maintain strict control of blood sugar levels. For healthy younger people, this means keeping the target blood sugar level (known as A1c or HbA1c) lower than 6.5 percent to 7.0 percent.

For older adults who have a limited life expectancy or who have advanced dementia, however, maintaining that target blood sugar level may cause more harm than good. For example, these older adults may not live long enough to experience potential benefits. What’s more, maintaining these strict blood sugar levels can raise the risk of potentially harmful events such as low blood sugar (also known as hypoglycemia). This can cause falls or loss of consciousness.

For these reasons, many guidelines now suggest targeting higher HbA1c targets—such as between 8.0 percent and 9.0 percent—for older adults who have multiple chronic conditions or limited life expectancy, or who live in nursing homes.

There is not much existing research to guide health care practitioners as to what the appropriate levels of diabetes medications are for this group of older adults. There is also little information about the effects for these individuals of taking fewer or lower dose of diabetes medications.

Experts suspect that lessening diabetes treatment in these older adults has the potential to prevent unnecessary hospitalizations due to lowering the risk for harmful drug events and increasing the patients’ comfort.

In order to investigate the issue, a team of researchers conducted a study—one of the first national studies to examine potential overtreatment and deintensification of diabetes management in nursing home residents with limited life expectancy or dementia. The researchers chose nursing home residents to study because admission to a nursing home could give healthcare practitioners a chance to learn more about patient goals and preferences and to review and adjust medications accordingly. The researchers published their results in the Journal of the American Geriatrics Society. Continue reading →

For Older Adults with Heart Failure: Can Taking Too Many Medications Reduce the Ability to Perform Daily Activities?

Posted on by

Journal of the American Geriatrics Society Research Summary

As we age, we tend to develop a number of chronic health conditions and concerns. Often, managing health problems can mean that older adults may take many different medications. When older adults take five or more medicines (a scenario health experts call “polypharmacy”), it can increase the risk of harmful side effects.

Polypharmacy can contribute to serious problems including falls, disability, and hospitalizations. Taking more than five medications is especially common among older adults with heart failure, which is the leading cause of hospitalization for people age 65 and older. Doctors often prescribe several different drugs to improve heart failure, but this can increase your risk of harmful side effects and interactions between your medications. Older adults who have trouble performing routine daily activities are at a particularly high risk for the negative effects of taking a large number of medications.

In a new study, researchers examined whether limitations in older adults’ abilities to perform their routine daily activities were linked to taking multiple medications for heart failure. They published their study in the Journal of the American Geriatrics Society. Continue reading →

Antipsychotic Use in Older Adults After Heart Surgery

Posted on by

Journal of the American Geriatrics Society Research Summary

Delirium is the medical term for an abrupt, rapid change in mental function that goes well beyond the typical forgetfulness of aging. Delirium can cause you to become confused, potentially aggressive, agitated, sleepy, and/or inactive. Post-operative delirium can occur after you’ve had an operation, and is the most common complication older adults experience after they have surgery. Older adults are at high risk for post-operative delirium after they have heart surgery.

When older adults have post-operative delirium, they are often given antipsychotic medications (APMs).  However, these drugs are not proven to be effective for treating delirium and may be harmful. Experts suggest that these drugs do not reduce how often or for how long older adults may experience delirium, or how serious the effects of delirium may be.

Additionally, some studies in older adults with dementia have found that APMs may cause heart rhythm problems and other drug-related side effects. Taking these drugs can increase the effects of anesthesia, and can cause stroke, pneumonia, and even death. Older adults who have had heart surgery are more likely to experience these dangerous events.

In a new study published in the Journal of the American Geriatrics Society, researchers looked into the use of APMs in older adults following heart surgery. Continue reading →

Are High-Risk Anticholinergic Medicines Prescribed Too Often for Older Adults?

Posted on by

Journal of the American Geriatrics Society Research Summary

Anticholinergics are a class of medications that are often prescribed for allergies, lung disease, and urinary incontinence. They also often can increase health risks for older adults. These medicines can affect your memory and ability to think, and they can even lead to increases in the risk for falls, dementia, and death. Additionally, older adults often have a difficult time tolerating anticholinergics because of age-related physical changes, such as reduced liver and kidney function, and because medications can impact our brain chemistry more strongly as we age.

Experts use tools to help older adults and healthcare professionals understand the risks associated with medications like anticholinergics. One of these tools is the AGS Beers Criteria for Potentially Inappropriate Medication Use in Older Adults. The AGS Beers Criteria details medications with risks that may outweigh their benefits for older adults. The AGS Beers Criteria identifies 52 “high-risk” anticholinergics. Thirty-five of these are included on a list of medications worth avoiding altogether for older people, unless a healthcare professional has a compelling reason for prescribing them on a case-by-case basis.

Recently, a team of researchers decided to study how frequently healthcare providers prescribe potentially inappropriate medications like anticholinergics in light of recommendations like those from the AGS Beers Criteria. Their study was published in the Journal of the American Geriatrics Society. Continue reading →
