The trend of osteoporosis and osteoporotic fragility fractures in inpatients: results from a national database

Abstract

Osteoporosis is associated with an increased risk of pathologic fractures; however, most patients do not receive diagnosis and adequate treatment. The aim of our study was to compare the yearly trends of osteoporosis and osteoporotic fragility fractures in the USA (US) inpatients. We used National (Nationwide) Inpatient Sample database to identify adults ≥18 years with diagnoses of osteoporosis and pathologic fractures and excluded pathologic fractures due to other etiologies. We then studied the annual trends, in terms of annual percentage change (APC), of osteoporosis and osteoporotic fractures. Among overall hospitalizations, osteoporosis was noted to have an increasing trend from 2000 to 2009 (APC = 5.81, p < 0.05) with a decline thereafter (APC = – 3.88, p < 0.05). In contrast, osteoporotic fracture showed an initial downward trend from 2000 to 2010 (APC = −7.31, p < 0.05), followed by a slowly rising trend (APC = 2.0, p = NS). The initially increasing trend of osteoporosis was followed by a decreasing trend thereafter. In contrast, there was a halt in a previously declining trend of osteoporotic fracture. Potential explanations include inadequate screening and treatment per guidelines along with decreasing patient compliance. In conclusion, primary and secondary prevention measures for osteoporosis have been underutilized by both physicians and patients alike.
