Do we understand each other when we develop and implement hip fracture models of care? A systematic review with narrative synthesis

Abstract

Background A hip fracture in an older person is a devastating injury. It impacts functional mobility, independence and survival. Models of care may provide a means for delivering integrated hip fracture care in less well-resourced settings. The aim of this review was to determine the elements of hip fracture models of care to inform the development of an adaptable model of care for low and middle-income countries (LMICs). Methods Multiple databases were searched for papers reporting a hip fracture model of care for any part of the patient pathway from injury to rehabilitation. Results were limited to publications from 2000. Titles, abstracts and full texts were screened based on eligibility criteria. Papers were evaluated with an equity lens against eight conceptual criteria adapted from an existing description of a model of care. Results 82 papers were included, half of which were published since 2015. Only two papers were from middle-income countries and only two papers were evaluated as reporting all conceptual criteria from the existing description. The most identified criterion was an evidence-informed intervention and the least identified was the inclusion of patient stakeholders. Conclusion Interventions described as models of care for hip fracture are unlikely to include previously described conceptual criteria. They are most likely to be orthogeriatric approaches to service delivery, which is a barrier to their implementation in resource-limited settings. In LMICs, the provision of orthogeriatric competencies by other team members is an area for further investigation.
