Abstract:

Objective

To design a visual hip joint function rating system presented through pictures and videos for self-evaluation by patients based on the Harris score, and to verify its feasibility and accuracy.

Methods

An observational randomized crossover design study was conducted on patients discharged from hospital after unilateral hip replacement or core decompression at Sun Yat-sen Memorial Hospital from January 2020 to December 2023. Severe senile dementia or other psychological diseases, and incompleted data were excluded. The consistency of the Harris score, simplified Harris score, and visual hip joint score were evaluated by analysis of variance, Kendall rank correlation analysis, and Bland-Altman plot. The feasibility of visual hip joint sore by patients was assessed through analysis of evaluation process time and response rate.

Results

Compared to the simplified Harris score, the visual hip joint score had a more concentrated distribution of scores within the 95% consistency limits (-4.25, 9.47). The visual hip joint score had lower misjudgment rate compared to the simplified Harris score (38% vs. 23%, χ2=4.309, P=0.038) in terms of grade assessment. The evaluation process time for the visual hip joint score was shorter than that for the Harris score(F=19.753, P<0.001). The satisfaction survey showed the highest satisfaction with the visual hip joint score(F=20.659, P<0.001).

Conclusions

The visual hip joint score for self-evaluation by patients is consistent and highly correlated with the Harris score. It provides more accurate grade assessment compared to the simplified Harris score previously used for self-evaluation by patients, and has good accessibility. It can meet the needs of accurate and convenient self-assessment by patients and better promote the development of remote follow-up.
