Simple Hip Value: a simple score to evaluate Hip function.

Area of Science:

• Orthopedics
• Medical Assessment Tools
• Patient-Reported Outcomes

Background:

• Existing hip function questionnaires (HOOS-12, Oxford-12) can be difficult to deploy in clinical practice.
• Single-question assessments have shown relevance for shoulder and knee function.
• The utility of a single-question hip function assessment has not been previously evaluated.

Purpose of the Study:

• To develop and assess the Simple Hip Value (SHV) test, a single-question patient-completed questionnaire for hip function.
• To evaluate the relevance, discriminatory capacity, and reproducibility of the SHV test.
• To test the hypothesis that a single-question PROM for hip function is reliable and useful in clinical practice.

Main Methods:

• Prospective comparative diagnostic study involving 74 total hip arthroplasty patients and 20 healthy controls.
• Patients completed the SHV, HOOS-12, and Oxford-12 questionnaires, with scores scaled to 100 points.
• Reproducibility was assessed by re-administering questionnaires to 20 patients; discrimination was evaluated using control subjects.

Main Results:

• The SHV test showed strong correlations with Oxford-12 (Spearman: 0.63) and HOOS-12 (Spearman: 0.66).
• The SHV demonstrated excellent reproducibility (ICC: 0.82) and significant discrimination from a healthy control group (90.0 vs 100.0, p < 0.001).
• Median SHV score was 90/100, compared to Oxford-12 (88.5) and HOOS-12 (79.1).

Conclusions:

• The SHV test is a reliable, reproducible, and discriminating tool for assessing hip function post-total hip arthroplasty.
• The SHV offers a simplified and practical approach for practitioners evaluating hip function.
• Further validation in diverse populations is recommended to confirm the SHV test's utility.
