Insights
The Hip Outcome Score (HOS) and International Hip Outcome Tool-12 (iHOT12) strongly correlate in hip pain patients. Collecting HOS with gender information may be sufficient, reducing the need for both assessments.
Area of Science:
- Orthopedics
- Rehabilitation Medicine
- Health Outcomes Research
Background:
- Hip pain significantly impacts patient quality of life and functional status.
- Standardized outcome measures are crucial for evaluating treatment effectiveness in hip conditions.
- The International Hip Outcome Tool-12 (iHOT12) and Hip Outcome Score (HOS) are commonly used patient-reported outcome measures for hip conditions.
Purpose of the Study:
- To assess the correlation between the iHOT12 and HOS in patients experiencing hip pain.
- To determine if demographic factors influence the relationship between iHOT12 and HOS scores.
- To evaluate the redundancy of using both iHOT12 and HOS in clinical practice.
Main Methods:
- A cross-sectional study involving 91 hip pain patients attending an orthopedic clinic.
- Patients completed paper surveys including the iHOT12 and HOS.
- Demographic data (age, weight, height, BMI) and gender were collected; statistical analysis included Pearson's correlation and linear modeling.
Main Results:
- A strong positive correlation was found between iHOT12 and HOS scores (r=0.79, P<0.001), with HOS explaining 62% of the variation in iHOT12.
- Gender was a significant predictor for iHOT12 scores (P=0.007) but not for HOS.
- The correlation was stronger in males (r=0.81) than females (r=0.77).
Conclusions:
- The iHOT12 and HOS demonstrate high predictive power for each other, suggesting potential redundancy.
- Collecting the HOS along with gender information may be a more efficient approach than collecting both outcome scores.
- This finding can streamline patient data collection in hip pain management while maintaining robust outcome assessment.
Abstract:
To determine if scores of the International Hip Outcome Tool-12 (iHOT12) and the Hip Outcome Score (HOS) correlate with one another in hip pain patients. Patients reporting to an orthopedic clinic for their scheduled appointment for hip pain were given a paper survey consisting of the iHOT12 and the HOS. Demographic information [age, weight, height and body mass index (BMI)] was obtained by chart review. Overall, 114 patients were invited to voluntarily complete the surveys of which 23 declined. Our sample consisted of 91 (57 female and 34 male) patients (80% response rate). The HOS (iHOT12) explained 62% of the variation in iHOT12 (HOS) by using a linear model (Pearson's correlation(r) is 0.79, P < 0.001). Age, weight, BMI, gender and arthritis did not show a statistically significant predictive power explaining HOS. However, only gender had a 'statistically' significant predictive power explaining iHOT12 (P = 0.007). The relationship between the two scores are stronger for males (r = 0.81, P < 0.001) compared with females (r = 0.77, P < 0.001). The proportion of variations explained on one of the scores by the other are 0.66 for males and 0.59 for females. HOS score together with gender explained 64% of the variation in iHOT12 by using a linear model. iHOT12 together with the non-statistically significant gender term explained 62% of the variation in HOS by using a linear model. It may not be necessary to collect both the iHOT12 and HOS, since the predictive power of one on the other is high. Collecting HOS together with information on gender is preferable compared with collecting iHOT12. Level of evidence: Level III.
