Long-term use of proton pump inhibitors raised hip fracture risk.
* Clinical question
Does the long-term use of proton pump inhibitors (PPIs) increase the risk of hip fracture?
* Bottom line
Yes, the long-term use (>1 year) of PPIs is associated with an increased risk of hip fracture among adults older than 50 years. Risk is also higher among individuals taking higher doses of PPIs and increases with duration of use. Physicians will need to carefully assess appropriate use, dose, and duration of therapy on an individual basis.

Significant hypochlorhydria as a result of PPI therapy may cause calcium malabsorption, resulting in a higher risk of bone fractures. These investigators analyzed data obtained from the United Kingdom General Practice Research Database relating to prescription use and subsequent diagnoses and hospitalizations for hip fracture.
Cases consisted of individuals who were older than 50 years, and who had a first occurrence of hip fracture at least 1 year after the beginning of their standard follow-up period. Up to 10 controls were selected for each case, matching for multiple variables including sex, year of birth, and duration of follow-up. The authors performed a statistical analysis of the data to control for other potential confounders, including body mass index, smoking history, alcoholism, impaired mobility, atherosclerotic vascular disease, peptic ulcer disease, and renal failure.
There were 13,556 hip fracture cases and 135,386 controls. PPI use for more than 1 year was associated with a significantly increased risk of hip fracture (adjusted hazard ratio=1.44 [95% confidence interval, 1.30-1.59]; number needed to harm per person-years=1266 [95% CI, 944-1856). The associated risk was further increased among patients taking higher doses of a PPI and with increasing duration of use. Histamine-2 receptor antagonist therapy (eg, ranitidine, cimetidine) did not significantly increase hip fracture risk.
Patients taking higher doses of PPIs had an even greater risk of hip fracture
