A systematic review of the association between early comprehensive geriatric assessment and outcomes in hip fracture care for older people

Aims Performance indicators are increasingly used to improve the quality of healthcare provided to hip fracture patients. Joint care, under orthopaedic surgeons and physicians with an interest in older patients, is one of the more common indicators of high-quality care. In this systematic review, we investigated the association between ‘comprehensive geriatric assessment’ and patient outcomes following hip fracture injury. Methods In total, 12 electronic databases and other sources were searched for evidence, and the methodological quality of studies meeting the inclusion criteria was assessed.The protocol for this suite of related systematic reviews was registered with PROSPERO (ID: CRD42023417515). Results A total of 24,591 articles were reviewed, and 39 studies met the inclusion criteria for the review, involving a total of 25,363 patients aged over 60 years with a hip fracture. There were five randomized clinical trials, three quasi-experimental studies, two non-randomized parallel group control trials, 22 pre-/post-intervention studies, and seven retrospective cohort studies, conducted between January 1992 and December 2021. The timing and content of a comprehensive geriatric assessment was ill-defined in many studies and care pathways were heterogeneous, which precluded meta-analysis of the data. Early comprehensive geriatric assessment was associated with improved outcomes in 31 of the 36 (86%) patient-reported outcomes, including improved mobility (acute/ long-term), functional status, and better quality of life. In total, 155 out of 219 (70.78%) clinical outcomes derived from hospital records showed a positive association with early comprehensive geriatric review, including reduced preoperative time and length of hospital stay, reduced incidence of postoperative complications, fewer hospital readmissions, and lower mortality. Conclusion Early comprehensive geriatric assessments after hip fracture in older people is associated with improved patient-reported outcomes and better clinical outcomes such as reduced incidence of complications, length of hospital stay, preoperative waiting time, and mortality. Standardization of the definitions of ‘early’ and ‘comprehensive’ geriatric assessments and consistent reporting of care pathway models would improve future evidence synthesis.
