Neuman MD, Elkassabany NM, Ochroch J, et al. - Researchers defined contemporary use of peripheral nerve blocks after hip fracture over time and identified predictors of nerve block receipt. A retrospective cohort study was designed to include claims data from one large national private US insurer. The study population consisted of a total of 94,985 adults aged 50 years and older hospitalized for a femoral neck, intertrochanteric, or subtrochanteric fracture; 409,263 adults aged 50 years and older hospitalized for elective hip or knee arthroplasty between 2004 and 2016. The findings of this research reveal that fewer than 5 of every 100 patients hospitalized with hip fracture currently receive a peripheral nerve block, implying possible underuse, although use of peripheral nerve blocks for pain control after hip fracture has increased over time.
