Residents with dementia taking so-called SSRIs seem to be at higher risk of injury, study suggests.

WEDNESDAY, Jan. 18 (HealthDay News) -- Antidepressants called
selective serotonin reuptake inhibitors (SSRIs) are associated with an
increased risk of falls in nursing home residents with dementia, a new
study finds.
Researchers in the Netherlands analyzed data about daily prescription
medicine use and falls among 248 nursing home residents with dementia.
The dataset collected between Jan. 1, 2006 and Jan. 1, 2008 included
85,074 person-days.
Antidepressants were used on 13,729 days (16 percent), with SSRIs used on 11,105 of these days, the investigators found.
A total of 683 falls were experienced by 152 (61.5 percent) of the
248 nursing home residents, which works out to fall incidence of 2.9
falls per person-year. Thirty-eight residents had one fall but 114 had
frequent falls.
Injury or death resulted from 220 of the falls: 10 were hip
fractures, 11 were other types of fractures, and 198 were injuries such
as sprains, bruises, swelling and open wounds. One person died after
falling, according to the results.
The researchers found that the risk of having an injury-causing fall
was three times higher for residents taking SSRIs than for those who
didn't take the antidepressants. For example, the absolute daily risk of
a fall was 0.28 percent for an 80-year-old woman taking a daily dose of
an SSRI, compared with 0.09 percent for a woman the same age who didn't
take an SSRI.
Similar increases in risk were found for both women and men of different ages, according to the study published Jan. 19 in the
British Journal of Clinical Pharmacology.
"Our study also discovered that the risk of an injurious fall
increased even more if the residents were also given hypnotic or
sedative drugs as sleeping pills," lead author Carolyn Shanty Sterke,
who works in the section of geriatric medicine at Erasmus University
Medical Center in Rotterdam, said in a journal news release.
Falls are a major issue for nursing home residents with dementia, and
one-third of falls among nursing home residents result in an injury,
the study authors noted.
"Staff in residential homes are always concerned about reducing the
chance of people falling and I think we should consider developing new
treatment protocols that take into account the increased risk of falling
that occurs when you give people SSRIs," Sterke said in the news
release.
While the study uncovered an association between injury-causing falls
and SSRI use, it did not prove a cause-and-effect relationship.
