People
who end up in an emergency room following a fall most likely lost their balance
due to an infection, not poor eyesight or tripping hazards alone, according to
new research.
Blood,
urinary, and respiratory infections are the most common reasons someone,
especially an elderly person, falls, according to a new study released by the
Massachusetts General Hospital in Boston. Many falls that put someone in an
emergency room are blamed on a loose rug or bad vision, the researchers said.
"Over
the years I've been struck by the fact that some of the more serious infections
I treated were in people who came to the hospital because they fell," said
Farrin A. Manian, MD, lead investigator of the study and a clinician educator
in the Division of General Medicine at Massachusetts General Hospital. "Even
though many of the patients had vague early signs of an infection, such as
weakness, or lethargy, it was the fall that brought them in."
The
researchers found that infections also cause younger people to take falls that
lead them to a hospital: 20 percent of 161 patients involved in the study were
under the age of 65. All patients had fallen, ended up in an emergency room,
and then were diagnosed with a "coexisting infection."
"Of
those, 71 (44.1 percent) had a urinary tract infection, 64 (39.8 percent) had a
bloodstream infection, 37 (23.0 percent) had a respiratory infection and 9 (5.6
percent) had an infection of the heart valve," according to a press release on the study.
More
than 40 percent of patients were not suspected of having a coexisting infection
because the majority had one or none of common indicators of such a condition,
including fever or rapid heart rate.
As
many as 45 percent of such falls are ultimately caused by infection, according
to past research cited by the study. Infections can trigger low blood pressure,
which can lead to dizziness and disorientation, or also sow confusion among
those with dementia, the researchers said.
"Ultimately,
we hope that the public can also become more attentive to subtle signs of
infections in some patients, the elderly in particular, so that perhaps these
infections can be diagnosed and treated before the fall actually occurs,"
Manian told The Washington Post (SEE BELOW).
The
study was presented Friday at IDWeek, an annual meeting concerning infectious
diseases.
About 2.5 million elderly
persons end up in American emergency rooms each year as a result of
falls, according to the US Centers for Disease Control and Prevention,
with less than a third of them requiring hospitalization. The death rate
of these falls has increased, from 41 deaths per year for every 100,000 falls
to 57 deaths between 2004 and 2013.

Reason Why Some People Fall.

Every
year, more than two million seniors wind up in the emergency room because they
fell. And one out of five falls results in a serious injury, such as broken
bones or a head injury.
Most
falls are blamed on risk factors such as medications that can affect balance,
vision problems, and throw rugs that can be tripping hazards.
But
researchers now suggest that clinicians, family members and caregivers consider
another offender: infections.
Bloodstream,
urinary and respiratory infections are the most common culprits for
infection-related falls, according to a study presented Friday in San Diego at
an annual meeting on infectious diseases known as IDWeek.
The
findings by researchers at the Massachusetts General Hospital in Boston also
suggest that while these falls may be more common among those 65 and older,
they shouldn't be overlooked in younger people: 20 percent of patients in the
study were younger than 65.
Many
people, including family members, caregivers and even some clinicians, don't
recognize the connection. People can fall because an infection may cause low
blood pressure and make someone feel lightheaded or dizzy, or because it adds
to confusion in older patients with dementia, according to the researchers.
Farrin
A. Manian, a clinician educator at Massachusetts General Hospital and the
study's principal investigator, said in an e-mail that he hoped the study could
increase awareness of falls as "being a potential manifestation of an
infection" for both the public and health-care workers.
"Ultimately,
we hope that the public can also become more attentive to subtle signs of
infections in some patients, the elderly in particular, so that perhaps these
infections can be diagnosed and treated before the fall actually occurs,"
he said.

Researchers
analyzed 161 patients who went to the emergency room at Massachusetts General
Hospital because they fell and were subsequently diagnosed with a coexisting
infection. Clinicians did not initially suspect infection in 41 percent of the
patients because the majority had few, if any, obvious signs, such as fever.
"Over
the years I've been struck by the fact that some of the more serious infections
I treated were in people who came to the hospital because they fell," Manian
said. "Even though many of the patients had vague early signs of an
infection, such as weakness, or lethargy, it was the fall that brought them
in."
There has been previous research about the association of infections with falls, but those focused primarily in the elderly with dementia and urinary tract infections or people who lived in institutions, he said. The new study is the first to systematically look at the relationship between infections and falls in a general population. Nearly 80 percent of the patients in the study were living at home.
