As the population continues to age, the prevalence of spinal deformity surgery for older patients is increasing. It is not well-known whether or not it is suitable to perform large spinal procedures (spinal fusion of at least 5 levels) in these patients and whether the outcomes merit the risks involved. Published studies have shown improved outcomes with adult spinal deformity surgery; however, whether these results are generalizable to all patients undergoing these procedures are unknown. In elderly patients, complications are known to happen more often compared to young patients, hospital stays are prolonged, and associated costs are increased. Therefore, the AOSpine KF Deformity initiated PEEDS – an international multicenter study to determine the value of spinal deformity surgery in adult spinal deformity patients over the age of 60.

 

This study is being led by Principal Investigator, Dr. Stephen Lewis, Orthopaedic Spine Surgeon from the University of Toronto, and Co-principal Investigator, Dr. Sigurd Berven, Orthopaedic Spine Surgeon from the University of California San Francisco.

 

"With the help of this international panel of experienced spinal deformity surgeons and their research teams, we hope to provide some needed answers to the numerous questions in the surgical management of adult deformity based on the findings of these closely monitored cases." says Dr. Stephen Lewis.

 

"The PEEDs study will investigate the utility and value of multilevel fusion surgery in patients over age

60. Multilevel fusion in older patients is a procedure that is rising rapidly across healthcare systems, and accounts for significant costs internationally. Our interest is to demonstrate the utility and value of the surgery, and to clearly document complications and risks of surgery. Informed choice is an important goal for patients and physicians, and information gained from this study will empower patients and surgeons to participate in informed decision making regarding surgical reconstruction of the spine." says Dr. Sigurd Berven.

 

PEEDS is being conducted internationally at 12 clinical research sites in 8 countries and 3 regions (5 North American, 3 Asian, and 4 European) around the world. AO Clinical Investigation and Documentation (AOCID) is coordinating this study. Currently, 83/225 (37%) patients have been enrolled. Recruitment is planned to be complete by the end of 2015.
