His research focuses on improving patient-centered outcomes for older adults undergoing surgery and anesthesia. He is the founding Director of the Penn Center for Perioperative Outcomes Research and Transformation (CPORT), which focuses on promoting high-quality comparative effectiveness research and implementation science to improve the effectiveness and efficiency of care for patients with surgical conditions and other acute illnesses. Dr. Neuman is the principal investigator of the REGAIN multicenter trial, a PCORI-funded international randomized trial comparing the impact of spinal anesthesia versus general anesthesia on functional recovery at up to one year after hip fracture surgery. His other work has used retrospective methods to evaluate the relationship between quality of acute and post-acute care and long-term outcomes, such as recovery of functional independence, among patients hospitalized with hip fracture and other acute conditions.
