The INTACT-HIP trial study will evaluate feasibility of conducting a randomized, double-blinded controlled trial comparing postoperative treatment with intravenous (IV) acetaminophen versus oral acetaminophen, in older adults undergoing hip fracture surgery. The results of this feasibility trial will be used to inform designing a larger, multi-center, randomized controlled trial to assess the efficacy of IV acetaminophen compared to oral acetaminophen to reduce delirium and improve other clinical and patient-centered outcomes after hip fracture surgery. It will randomize 42 older adults to receive either oral or IV acetaminophen after hip fracture surgery.
