This qualitative study interviewed general practitioners, patients, and FLS clinicians and identified key challenges facing stakeholders seeking to improve post-fracture osteoporosis care. Local policies and care pathways as an initial strategy may address information and service delivery issues across the acute-primary care divide. Introduction Fracture liaison services (FLS) can be effective for secondary fracture prevention, but long-term adherence to therapies remains suboptimal. Few studies have explored how services manage the transition between tertiary and primary post-fracture care. This study mapped service processes and factors influencing integration of post-clinic care, identifying barriers, supports, and opportunities for seamless healthcare. Methods Qualitative descriptive study using semi-structured interviews with FLS stakeholders at two metropolitan hospitals in New South Wales (NSW) and surrounding general practices. Results Seven FLS clinicians, 11 general practitioners (GPs), and seven patients were interviewed. Six key themes emerged on the transition of patient care from tertiary to primary care (PC). Interprofessional communication issues and role ambiguity posed threats to seamless care. Delayed, absent, inaccessible, or poor-quality communication frustrated GPs, while FLS clinicians lacked confidence in existing communication systems and desired bidirectional communication with PC. GPs were confident managing osteoporosis, but FLS clinicians had limited confidence that patients would discuss osteoporosis with their GP and that GPs would action recommendations. Effective PC follow-up required a positive GP-patient relationship and that patients perceived a need to engage with PC. Patient understanding of osteoporosis (influenced by patient education, knowledge, beliefs, and health behaviours) affected PC attendance. Limited public awareness of osteoporosis and healthcare policy deficits contributed to care gaps. Conclusion Key challenges were identified facing stakeholders seeking to improving post-clinic osteoporosis care. Development and implementation of local, integrated acute-community policies and care pathways as an initial intervention may address information and service delivery issues across the acute-PC divide.
