Validation of the HOOS, JR: A Short-form Hip Replacement Survey

Abstract

Background Patient-reported outcome measures (PROMs) are increasingly in demand for outcomes evaluation by hospitals, administrators, and policymakers. However, assessing total hip arthroplasty (THA) through such instruments is challenging because most existing measures of hip health are lengthy and/or proprietary. Questions/purposes The objective of this study was to derive a patient-relevant short-form survey based on the Hip disability and Osteoarthritis Outcome Score (HOOS), focusing specifically on outcomes after THA. Methods We retrospectively evaluated patients with hip osteoarthritis who underwent primary unilateral THA and who had completed preoperative and 2-year postoperative PROMs using our hospital's hip replacement registry. The 2-year followup in this population was 81% (4308 of 5351 patients). Of these, 2371 completed every item on the HOOS before surgery and at 2 years, making them eligible for the formal item reduction analysis. Through semistructured interviews with 30 patients, we identified items in the HOOS deemed qualitatively most important to patients with hip osteoarthritis. The original HOOS has 40 items, the four quality-of-life items were excluded a priori, five were excluded for being redundant, and one was excluded based on patient-relevance surveys. The remaining 30 items were evaluated using Rasch modeling to yield a final six-item One or more of the authors (SL, PDF) has received rsearch support funding from the Agency for Healthcare Research and Quality (Rockville, MD).

“…Finally, patients for this study were recruited from a high-volume specialized orthopaedic hospital and may not be representative of the population of patients undergoing THA and TKA in the United States. However, prior research has shown that patients in our registries are generally similar to those in the nationally representative Function and Outcomes Research for Comparative Effectiveness in Total Joint Replacement and Quality Improvement (FORCE-TJR) registry [14,15].…”

Cementless neck preserving arthroplasty should be the treatment of choice in cases of coxarthrosis in middle-aged men: very good results in a mid-term follow-up study with NANOS stem and Verilast articulation

“…Among the 137 patients who met the inclusion criteria, the invitation was ac- cepted by 106 individuals. During the medical appointments at the hospital outpatient clinic, the patients completed the HHS [8,9], HOOS [10,11] and OHS questionnaires [12,13]. X-ray images of the pelvis in the anterior-posterior projection, and axial images of the examined hip joint, were taken in order to assess the placement of the implant, presence of osteolysis zones around the acetabulum (according to DeLee [14], Fig.…”
