Quantitative evaluation of the degrees of traditional Chinese medicine qualitative syndromes of osteoporosis

Abstract

To establish a quantitative estimate model for diagnosing traditional Chinese medicine (TCM) syndromes of patients with osteoporosis. Symptoms and signs of osteoporosis and methodology related to syndrome research were collected by reviewing medical literature. The symptoms and sighs were quantitatively classified into three, two or one category according to a 100-mm visual analog scale. Fuzzy comprehensive evaluation model of TCM qualitative syndromes was performed based on analytic hierarchy process. Then "Hall for Workshop of Metasynthetic Engineering" expert symposium was held on subjects of syndrome quantification method and weight of evaluation indices in different levels for developing the analysis model of common syndromes. For clinical verification, the created models were applied to patients with osteoporosis for discriminating syndromes. Syndrome of each patient was also identified by 8 experts major in integrative medicine treating osteoporosis for comparing the coincidence rate using a self-made clinical questionnaire. Through literature reviewing, symptoms and signs quantification and expert discussing, the authors formed estimate models of essence deficit, qi deficiency, yin deficiency, yang deficiency, and blood stasis. A total of 220 patients with osteoporosis were enrolled and filled the clinical questionnaire. All 8 experts completed and returned the questionnaire (1 760 cases), and 1 545 of them were filled in completely. Experts' opinion on syndrome differentiation was exactly coincidence to estimate model in 611 cases and almost coincidence in 639 cases. The total coincidence rate reached to 94.05%. The estimate model for syndrome differentiation of osteoporosis has a high-coincidence rate with the fuzzy evaluation from experts, with good rationality and feasibility, and is worthy of promotion in the clinical study.
