A decade of increasing complexity in patients sustaining a hip fracture in England, Wales and Northern Ireland: a national cohort study using the National Hip Fracture Database dataset.

backgroundHip fractures (HF) are a major cause of morbidity and mortality and account for substantial health and social care costs. We report the incidence and characteristics of older patients (≥60 years) presenting with hip fractures (HFs) in England, Wales and Northern Ireland.

methodsWe conducted a national cohort study of HF events recorded in the National Hip Fracture Database (NHFD) between May 2011 and September 2023. HF incidence was derived using sex and age-banded mid-year population estimates from the Office for National Statistics to calculate at-risk population incidence for the whole cohort and by sex and age strata.

results735 436 HF events were included (71% female, mean age 82.9 years). Annual NHFD HF numbers increased across the study period from 55 832 to 63 341 (13.5%). However, overall incidence declined from 422.8 to 412.8 per 100 000 population. Divergence was observed between sexes, with falling incidence in females but rising in males. HF patients are presenting with greater systemic disease burden, with the proportion graded American Society of Anaesthesiologists ≥3 increasing in both females (66.4% to 80.4%) and males (73.4% to 84.3%).

conclusionDespite modest declines in overall incidence in women, absolute HF numbers continue to rise. The divergent sex-specific trends and substantial increase in patient comorbidity represent important shifts in HF epidemiology with implications for service capacity, risk stratification and secondary prevention strategies. This mandates urgent realignment of care resources to minimise the impact on patient mortality and economic health burden.
