Description
Evaluation
of Fracture Risk in Skilled Nursing Facility Population
| This study examined risk for hip fracture in
residents of long-term care facilities.
The main objective was to build the empirical foundation
for a prediction model that helps clinicians identify candidates
for osteoporosis evaluation and treatment. Data for this work came from the Minimum Data Set records for
over 46,000 residents living in nursing homes between July 1998
and July 2001. The
health status and care assessments for residents experiencing
incidental hip fractures were compared to those who did not.
Both broad and restrictive case definitions were applied
to create a range of risk values.
The analysis focused on potential risk factors independent
of bone mineral density values, which are often unavailable
in the institutional setting.
Factors independent of bone health but possibly related
to hip fracture include poor muscle functioning, structural
problems, and cognition impairments, all of which can contribute
to falls leading to fractures. The characteristics assessed here included:
gender, race, weight, height, age, cognitive impairment,
vision, incontinence, osteoporosis diagnosis, and activities
of daily living and history of falls. The importance of each
risk factor in predicting future fractures was assessed with
bivariate statistics and multivariate regression using COX hazard models.
