Pelvic fracture rates in community-living people with and without disability and in residents of nursing homes.

OBJECTIVES: There are limited data on the epidemiology of pelvic fractures. The purpose of this study was to calculate incidence rates of pelvic fractures leading to hospital admission and to compare incidence rates between residents of nursing homes and community-dwelling persons with and without care need.
METHODS: Data were retrieved from a database of the largest health insurance company in Bavaria, Germany. Between 2004 and 2009, 10,170 pelvic fractures were observed in 751,101 women and 491,098 men. Age- and gender-specific incidence rates were calculated. Incidence rates were further stratified by setting (nursing home versus community) and functional status (no care need versus care need for those in the community). In addition, the average cumulative risk for a pelvic fracture at different ages was calculated.
RESULTS: The incidence rate increased from 0.54 and 0.38 per 1000 person-years in women and men aged 65 to 69 years to 9.35 and 4.45 per 1000 person-years in women and men aged 90 years and older, respectively. Persons living in a nursing home or living at home with care need had considerably higher incidence rates than community-dwelling older persons without care need. The average cumulative risk at the age of 65 years for an incident pelvic fracture until the age of 90 years was 6.9% in women and 2.8% in men.
CONCLUSION: The incidence of pelvic fractures leading to hospital admission is higher in women than in men and rises dramatically with increasing age. Persons with care need have a particularly high risk for pelvic fracture.
