EP8.26 Changes in Some Specific iHOT-12 Item Scores Are Associated with PASS Achievement in FAIS Patients Within One Year After Hip Arthroscopy

Abstract Purpose To identify what aspects of hip-related quality of life are more closely associated with achieving the patient acceptable symptom state (PASS) within one year after hip arthroscopy for femoroacetabular impingement syndrome (FAIS). Methods Patients with FAIS undergoing hip arthroscopy were included. Individual aspects of hip-related quality of life were assessed using the iHOT-12 items, each scored on a scale from 0 to 100, with higher scores indicating better hip-related quality of life. PASS was assessed using the anchoring question: “Taking into account your hip and groin function and pain, and how they affect your daily life, including your ability to participate in sport and social activities, do you consider your current state acceptable if it remained like this for the rest of your life?” with possible responses being “Yes” or “No”. Patients completed the iHOT-12 and PASS assessment preoperatively and at up to three postoperative timepoints (4, 8, and 12 months). For PASS achievers, the earliest postoperative timepoint at which a “Yes” response was reported was selected; for non-PASS achievers, the latest available timepoint was used. Separate logistic regression models were fitted with the pre-to-post treatment change in each iHOT-12 item as the main predictor, and PASS as the dependent variable, adjusted for sex, age, and postoperative timepoint (as categorical variable with three levels, with 4 months as the reference category). One model was fitted per item. Results A total of 51 participants (41.2±8.9 years; 60.7% women) were included, of whom 45% achieved PASS. Greater improvements in pain levels (Item 1) (OR=1.024; 95%CI=1.003–1.049), Child Carrying Concern (item 8) (OR=1.036; 95%CI=1.011–1.071), and Hip-Related Distraction (item 12) (OR=1.034; 95%CI=1.012–1.064) were associated with higher odds of achieving PASS. Conclusion Changes in only a subset of iHOT-12 items were associated with achieving PASS after hip arthroscopy for FAIS. Specifically, improvements in pain, concerns about carrying children, and the extent to which hip problems are perceived as a distraction were more closely related to achieving an acceptable symptom state. Examining changes at the item level may reveal clinically relevant information not reflected by the total iHOT-12 score. These findings should be interpreted with caution given the limited sample size.
