Defining inadequate response is very important in practical settings, for patients and clinicians and for the access and reimbursement of anti-osteoporotic drugs. However, many debatable points have been raised in defining which clinical signs constitute a non-response.

The objective of the working group is to establish an IOF Position Paper on what constitutes an inadequate response to osteoporosis treatment, based on the operational definitions published recently in a 2008 article ‘Inadequate responders to osteoporosis treatment: proposal for an operational definition’, co-written by Dr J. Gonzales-Macias and A. Diez Perez in the journal Osteoporosis International.
