Summary

What it measures:

The International Hip Outcome Tool (iHOT) was developed to measure quality of life for active patients with hip disorders.

• IHOT-33 contains 4 domains: (1) symptoms and functional limitations – 21 items; (2) sports and recreational activities – 18 items; (3) job-related concerns – 9 items; and (4) social, emotional, and lifestyle concerns – 12 items.¹
• iHOT-12 uses 12 items from the original 33.

Type of measurement: Patient reported outcome measure.

Target Population:

Patients ranging in age from 15-80 years, various activity levels, with various hip conditions including: chondral defects, trauma, femoroacetabular impingement syndrome (nonoperative care), labral tears, osteoarthritis, instability, loose bodies, Perthes, avascular necrosis, slipped capital femoral epiphysis, dysplasia, and postoperative hip arthroscopy (primary and revision).

Taskforce Recommendations

A 2023 clinical practice guideline from the Academy of Orthopaedic Physical Therapy and American Academy of Sports Physical Therapy, Hip Pain and Movement Dysfunction Associated With Nonarthritic Hip Joint Pain: Revision, recommends that clinicians use a validated outcome measure, such as iHOT, at baseline and at least one other follow-up point, which includes discharge to assess the impact of impairments of body function and structure on activity limitations and participation restrictions in those with nonarthritic hip joint pain.² (Grade A)

Clinical Insights:

• iHOT-33 is used in prospective clinical studies.
• iHOT-12 is often preferred for use in clinical practice (easier to administer due to shorter length and sensitivity to change is almost identical to iHOT-33^3,4).
• It is suggested to use iHOT for the initial assessment and postoperative follow up or reevaluations in routine clinical practice, as it is sensitive to change, and compared with other patient reported outcome measures, it does not appear to have a floor or ceiling effect.^3,5
• It does take time to measure each question and record scores individually.¹
