Abstract:

BACKGROUND: There are many criteria used to evaluate the curative effects of hip-preserving treatment for osteonecrosis of the femoral head, and there have been no consistent criteria, so the curative effects of hip-preserving treatment lack comparability to some extent.
OBJECTIVE: To develop a specific scale used to evaluate the curative effect of hip-preserving treatment reference to WHO Quality of Life Scale model of development and scale development and application of the medical field guide.
METHODS: Through the literature review and panel discussions, to design the theory model in reference to general scale under the guidance of related theory. Through the patient interview to form the entries pool, optimize the entries and get preliminary screening then form questionnaire. The field investigations were performed by pre-questionnaire, with the help of experts’ importance ratings, factor analysis, discrete trend method, regression, discriminant analysis and Cranach’s alpha coefficients to screen the entries, and finally form the eventually selected scale.
RESULTS AND CONCLUSION: The eventually scale including four areas: physiological, psychological, social and health consciousness. The scale was divided into nine aspects: pain, limp, joint function, the positive and negative factors, social role, social relations and healthy self-evaluation and understanding of disease, plus an independent entry, a total of 32 entries. Once the eventually selected scale of the hip-preserving treatment of osteonecrosis of the femoral head completed its scientific assessment, it will be a specific scale to evaluate the curative effect of the hip-preserving treatment of osteonecrosis of the femoral head, and will provide a more comprehensive outcomes assessment to the patients who accept the hip-preserving treatment of osteonecrosis of the femoral head.
