Estimation of resource utilization associated with osteoporotic hip fracture and level of post-acute care in China.

OBJECTIVE: Research suggests that the incidence and cost of treating osteoporotic hip fracture (OHF) in China is rising. The purpose of this study was to estimate resource utilization associated with OHF, including hospital length of stay (LOS) and inpatient costs, and to examine the level of post-acute care for osteoporosis among patients hospitalized for OHF in Shanghai, China.
METHODS: This was a retrospective study of 2855 patients aged 50 years and older who were hospitalized for bone fragility hip fractures in 13 districts of Shanghai in the 2000. One hundred and one patients were randomly selected and interviewed to determine the treatments and associated costs for the 6-month period following hospitalization. Log linear regressions with bootstrapping resampling were conducted for LOS and hospital cost data to estimate the average LOS and associated costs after adjusting for demographic and comorbid characteristics.
RESULTS: Hospital records of 2855 patients (mean age, 73.6 +/- 9.9 years) were reviewed. For women, mean LOS (35 days) was longer for those greater than 60 years of age; however, mean cost of hospital stay (15 082 RMB) increased to a peak at age 65-74 years (18 932 RMB). For men, mean LOS (34 days) and mean cost of hospitalization (13 149 RMB) both increased with age. Only 14% of patients hospitalized for OHF received treatment for osteoporosis. Due to the small number of patients and sampling that was taken largely for geographical convenience, care should be taken when generalizing these data into other areas of China.
CONCLUSIONS: OHF is associated with substantial resource utilization in Shanghai, China. Although patients hospitalized with OHF should be considered for osteoporosis therapy to alleviate economic and patient burden, most patients with OHF received no such treatment.
