IntroductionHip fractures have a high patient burden and mortality rate, particularly following revision surgery. Cement augmentation of cephalomedullary nails has been shown to lower the risk of cut-out, aiming to reduce the need and expense of revision surgeries. The aim of this study was to assess the economic impact of cement augmentation for the fixation of trochanteric hip fractures in fragile, elderly patients, across a range of European countries (UK, Spain, Italy, Germany, and France), from both a provider (hospital) and a payer perspective.MethodThe budget impact (hospital perspective) and cost-effectiveness (payer perspective) analyses were informed by clinical outcomes from a meta-analysis published in 2021, additional published literature, registries, and clinical experts. Economic inputs included length of stay and operating time for the hospital perspective, revision surgery, outpatient, and rehabilitation days costs for the payer perspective. Outcomes included the breakeven cost below which using cement augmentation would begin to generate cost savings for the hospital, and potential cost savings for the payer with incremental costs, quality-adjusted life years (QALYs), and incremental cost-effectiveness ratios (ICERs). Deterministic and probabilistic sensitivity analyses were conducted to assess model uncertainty.ResultsFrom a hospital perspective, the breakeven cost below which the hospital would start saving money using cement augmentation was £491 (UK), €1490 (Spain), €1075 (Italy), €852 (Germany), and €834 (France) per patient, driven by reduced length of hospital stay. From a payer perspective, cost savings were £1675 (UK), €2202 (Spain), €993 (Italy), €944 (Germany), and €892 (France) per patient, mainly driven by fewer revision surgeries. Payer cost savings, coupled with incremental QALY gain of 0.004 across all regions, led to cement augmentation being the dominant strategy. These budget impact and cost-effectiveness results were rigorously tested in sensitivity analyses and were found to be robust.ConclusionThese models support the wider adoption of cement augmentation to reduce the healthcare system costs associated with length of stay and revision surgery. These results provide useful information to providers, payers, and policymakers to ultimately influence choice surrounding the 'gold-standard' treatment of an unstable trochanteric fracture following low energy trauma.Copyright © 2024.
