When studying hip arthroscopy, providers rely on several different patient-reported outcome scores to collect information. These outcome scores (aka those pesky surveys we ask you to fill out) are then used to help surgeons figure out if what they do is helping people. Having patients fill out pre and post-operative surveys can help surgeons assess the effects of surgery on their patients.
One of the patient-reported outcome scores used by hip arthroscopists is the international hip outcome tool (iHot-12). Dr. Wolff and the surgeons in his MASH group wanted to figure out a way to measure how much a patient’s score on the iHot-12 needed to improve in order for the increase to be significant and meaningful. In our most recent publication in Arthroscopy, we assessed patient responsiveness to surgery by determining several different patient metrics such as the minimal clinically important difference (MCID), patient acceptable symptom state (PASS), and substantial clinical benefit (SCB). MCID is defined as the smallest change in outcome that the patient is able to appreciate, whereas PASS is defined as a satisfactory outcome status, and the SCB is considered the improvement in outcome that the patient considers a substantial improvement.
By determining these metrics, the MASH group armed surgeons with the ability to determine if the improvements that their patients had on the iHot-12 were meaningful. We were excited to not only provide the orthopaedic community with this information, but to apply these numbers to our own patient outcomes. We’re pleased to report that in our recent publication in the American Journal of Sports Medicine, patients undergoing both labral repair and labral reconstruction had improvements in the iHot-12 that met the PASS, MCID and SCB.
