Senior Citizens in Home Health Care at High Risk of Dangerous Medications
40% of seniors cared for by home health agency are taking a prescription that is potentially unsafe or
ineffective; Affordable Care Act offers hope
Dec. 2, 2011 – Senior citizens receiving home health care may be in danger of taking a drug that is unsafe or ineffective
for older people, says a new study that found nearly 40 percent of seniors receiving medical care from a home health agency are taking at
least one prescription medication that is considered potentially inappropriate for their age.
Dec. 8, 2003 - Forty-eight medications or classes
of medications to avoid in adults age 65 or older have been identified
by a national expert panel charged with updating widely used criteria
for potentially harmful medications in older adults.
The study's researchers, led by Dr. Yuhua Bao, assistant professor of public health at Weill Cornell Medical College,
found that home health care patients aged 65 and over are prescribed Potentially Inappropriate Medications, or PIMs, at rates three times
higher than patients who visit a medical office.
The researchers' data, published in the Journal of General Internal Medicine, show that home health care patients
are taking 11 medications on average, and that the concurrent use of multiple medications is a strong indicator of the presence of PIMs.
"Elderly patients receiving home health care are usually prescribed medications by a variety of physicians, and it's a
great challenge for home health care nurses to deal with prescriptions from many sources," says Dr. Bao.
Still, she sees the home health care model offering potential for improving this situation.
"Having a medical
professional enter an elderly patient's home is an opportunity to do a proper medication review and reconciliation," Dr. Bao explains.
The study used data from the National Home and Hospice Care Survey, conducted in 2007 by the Centers for Disease Control
and Prevention (CDC), which is the most recent nationally representative epidemiological survey of home health patients.
The 2002 Beers
Criteria, an expert-panel-generated list that itemizes 77 medications or groups of medications considered inappropriate for elderly people,
was the basis for the PIMs chosen.
In a review of data of 3,124 home health patients 65 years of age or older, the researchers found 38 percent were taking
at least one PIM. Senior patients taking 15 or more medications were five to six times as likely to be prescribed PIMs as patients taking
seven or fewer medications. Of those seniors taking at least one PIM, 21 percent were taking 15 or more medications.
According to Dr. Bao, the study, if anything, underestimates the prevalence of PIMs taken by home health patients: The
researchers were not able to look at potentially problematic drug-to-drug interactions or drug-and-disease interactions because data were not
There is no one reason why PIMs are prevalent in home health care settings, the study says.
"Anecdotal evidence shows that many physicians are not aware of what is on the PIM list," says Dr. Bao.
"In our fragmented health care system, we generally don't have an electronic reference for a patient that lists all
medications from different physicians, and there isn't a readily available means for professionals to share essential information. Enhanced
physician communication with home health care nurses may help to address the problem, as well as better communication among physicians."
Dr. Bao sees incentives for improvement in communication and care coordination in the implementation of the Patient
Protection and Affordable Care Act passed by the U.S. Congress in 2010.
"The current payment system doesn't provide incentives to optimize coordination of care," says Dr. Bao.
"But when providers in different settings as a group are held responsible for outcomes and costs of care through, for
example, an accountable care organization - a concept promoted in the Affordable Care Act - this could create an impetus to break the
communication barriers that currently exist."
