Background: Bisphosphonate medications, including alendronate, ibandronate and risedronate administered orally and zoledronate, administered intravenously, are commonly prescribed for the treatment of osteoporosis based on evidence that, correctly taken, bisphosphonates can improve bone strength and lead to a reduction in the risk of fragility fractures. However, it is currently unclear how decisions to select between bisphosphonate regimens, including intravenous regimen, are made in practice and how clinicians support patients with different treatments.
Methods: This was an interpretivist qualitative study. 23 semi-structured telephone interviews were conducted with a sample of general practitioners (GPs), secondary care clinicians, specialist experts as well as those providing and leading novel treatments including participants from a community intravenous (IV) zoledronate service. Data analysis was undertaken through a process of iterative categorisation.
Results: The results report clinicians varying experiences of making treatment choices, as well as wider aspects of osteoporosis care. Secondary care and specialist clinicians conveyed some confidence in making treatment choices including on selecting IV treatment. This was aided by access to diagnostic testing and medication expertise. In contrast GPs reported a number of challenges in prescribing bisphosphonate medications for osteoporosis and uncertainty about treatment choice. Results also highlight how administering IV zoledronate was seen as an opportunity to engage in broader care practices.
Conclusion: Approaches to making treatment decisions and supporting patients when prescribing bisphosphonates for osteoporosis vary in practice. This study points to the need to co-ordinate osteoporosis treatment and care across different care providers.
