Sustainability of a pharmacist-driven pathway for osteoporosis-related fractures on an orthopaedic unit after a 5-year period.

OBJECTIVES: Diagnosis and management of osteoporosis in hospitals are poor. Effective medications for reducing fracture risk are often underutilised in hospital settings. Studies have shown that improvements in secondary prevention of osteoporosis can occur with the implementation of clinical pathways and are effective in improving the prescription for osteoporosis medications. We aimed to assess the long-term sustainability of the benefit of the osteoporosis pathway implemented at The Queen Elizabeth Hospital, Adelaide, Australia, in 2003. METHODS: An audit was performed to review the rate of prescription for osteoporosis therapy 5 years after the implementation of a pharmacist-driven osteoporosis pathway in patients presented with a minimal trauma fracture and admitted to the Department of Orthopaedics at The Queen Elizabeth Hospital. KEY FINDINGS: Our review of a 5-year period shows that the rate of prescription for osteoporosis therapy in this patient group is 95%. CONCLUSIONS: The pharmacist-driven osteoporosis pathway at The Queen Elizabeth Hospital has sustained the rate of prescription for osteoporosis therapy over a prolonged period of time.

Effect of gastric acid suppression with pantoprazole on the efficacy of sevelamer hydrochloride as a phosphate binder in haemodialysis patients: a pilot study.

Sevelamer hydrochloride (HCL) is thought to require an appropriately acidic environment in order to bind gastrointestinal phosphate. Changes in gastric acidity with acid suppressants may therefore alter the efficacy of sevelamer HCL. Given the widespread use of acid suppression therapy in chronic kidney disease patients, there is potential for a common significant drug interaction to occur. This pilot study evaluated the in vivo effect of gastric acid suppression with pantoprazole on the efficacy of sevelamer HCL as a phosphate binder in maintenance haemodialysis patients. The study protocol was a cross-over, double-blinded, randomized, placebo-controlled trial in 10 haemodialysis patients randomly assigned to pantoprazole 40 mg daily or placebo for two consecutive 6-week periods. Serum phosphate was not significantly altered during pantoprazole compared with placebo treatment (1.61 ± 0.45 mmol/L vs 1.76 ± 0.42 mmol/L, P = 0.204). There were no differences in serum calcium, parathyroid hormone and bicarbonate. This pilot study demonstrates preliminary in vivo evidence for no effect of gastric acid suppression on the effectiveness of sevelamer HCL. Our results are limited by small sample size and therefore, larger experimental studies should be conducted. Although our study did not find a significant drug interaction, given the high prevalence of acid suppressant use in dialysis patients, physicians should be aware of the potential influence of acid suppression on the efficacy of phosphate binders and regularly assess the clinical need for acid suppression therapy.
