(HealthDay News) – Although there was a decrease in the prevalence of osteoporotic hip fracture from 1993–2008, due to the increase in the number of extreme elderly in the population, this coincided with an increase in the absolute number of hip fracture hospitalizations.
Amrita Sehgal, from the University of California in Berkeley, and colleagues reviewed 1993–2008 data from the Nationwide Inpatient Sample to assess the number and prevalence of hospitalizations for osteoporotic hip fracture in the elderly (65–79 years) and extreme elderly (≥80 years).
From 1993–2008, the researchers found that, although there was an increase in the number of elderly individuals, there was a decrease in hospitalizations for hip fracture (from 386 to 294 per 1,000 person-years). In the extreme elderly, there was an increase in hospitalizations for osteoporotic hip fracture (172,209 in 1993 to 180,428 in 2008), although the prevalence of hip fracture decreased from 2,236 to 1,600 per 1,000 person-years from 1993–2008. The increase in absolute number of hip fracture hospitalizations and concomitant decrease in prevalence of hip fracture coincided with an increase in the number of extreme elderly in the population, from 7.7 million in 1993 to more than 11.2 million in 2008. The extreme elderly accounted for 64% of osteoporotic hip fracture hospitalizations in 1993 and for >69% in 2008.
“We know that hip fracture in the extreme elderly is a serious problem due to the associated consequences of hospitalization, disability, and mortality,” Sehgal said in a statement. “[These] data [are] cause for concern as the impact highlighted will only increase along with this population segment.”
