Objective: To investigate an existing Trust-based osteoporosis service's preventative activity, determine any issues and problems and use this data to reorganise the service, as part of a National Health Service Executive/Regional Office-commissioned and funded study. Setting: A UK Hospital Trust's Osteoporosis Service. Design & Method: A Participatory Action Research (PAR) methodology was adopted, using PAR group sessions and reflective journals to collect and analyse qualitative data. Results: The service was investigated and found to be lacking in preventative osteoporosis-related activity. Subsequently, the research participants identified and implemented a range of preventative activities. Conclusion: Osteoporosis is a preventable disease that is known to place both a huge economic and social burden on societies worldwide. Despite this, evidence suggests that preventative osteoporosis activity is afforded a low priority within health services. This was the case with the osteoporosis service at the beginning of this study, but demonstrates how a service can be reorientated to accommodate a programme of preventative activity.
