引入PRO理念制作老年期癡呆臨床診斷分級量表的研究
[Abstract]:Objective: 1, to establish a PRO evaluation scale for the diagnosis of senile dementia, and to provide a new and practical means of.2 for the diagnosis and classification of senile dementia, and introduce the concept of PRO to evaluate the curative effect of traditional Chinese medicine for senile dementia more quantitatively.
Methods: combined with the international diagnostic criteria for dementia, 60 elderly patients were collected in accordance with the inclusion criteria. According to the internationally recognized MMSE, MoCA and CDR scales, 21 cases were divided into mild cognitive impairment group, 24 cases of mild dementia, 15 cases of moderate and severe dementia, the evaluation of A, B volume, and statistical analysis of the reliability, validity, differentiation and response rate of A, B volume, and test. The PRO scale for clinical diagnosis of senile dementia was identified, and a mathematical model was established by discriminant analysis, and the evaluation criteria were preliminarily worked out.
Results: 60 cases were included in this study, including 25 males and 35 females, with an average age of 72.05 + 8.05 years, which were divided into three groups, of which 21 cases were mild cognitive impairment, 35%, 24 in mild dementia, 40%, 15 in severe dementia group, 25.0%..
1, reliability test
With the Krone Bach a coefficient as the index, the A volume is 0.789, the B volume is 0.908, it has good internal consistency reliability. The half reliability indicates that the A and B volume are split into two parts respectively, and the two parts have good correlation. Therefore, A, B volume has good semi reliability.
2, validity test
The PRO evaluation scale used in this survey (A, B volume) is formed by previous literature research, scientific discussion and expert demonstration. It has the content validity from the compilation process. After the Spearman correlation coefficient test, the PRO scale A, the B volume score has a high linear correlation with MMSE, MoCA and CDR scores, which can be considered as a good standard. Quasi correlation validity. The structural validity of A and B volumes was tested by factor analysis. The three common factors extracted could explain 46.373% of the total variation in A volumes, 73.565% of the total variation of B volumes, and the rotation factor load matrix was obtained by the orthogonal rotation of variance. It was suggested that the B volume had a better structural efficiency. Considering the A volume as a self-assessment questionnaire for patients, and dementia There is a deviation in the identification of its own ability, and the information of all variables is low, but the coincidence of A volume with the expected design after factor analysis is still available, and it should be further verified after the further expansion of the sample survey.
3, distinction test
The total score of A and B volume in all cases were tested by Kruskal-Wallis test respectively. The results were all P0.01, suggesting that the scores of the three groups were significantly different. Therefore, A and B volume had good division.
4, the test of response rate
The positive response rate of each item in A and B volumes was tested, showing that A21 response rate of A volume item was lower, and the total response rate of B volume was higher than that of A volume.
5, discriminant analysis
Taking the scores of A volume and B volume as discriminant index variables, taking group as category variables, multi classification discriminant analysis is carried out, and a set of discriminant function models are established, the correct rate is 82.6%, and the correct judgment rate for each group is 84.6%, 78.3% and 90.0%., respectively.
6, A, B volume range of each group
The case A and B volume score were observed and the scores of A volume and B volume of each group were preliminarily summarized. Conclusion: 1, the dementia PR0 scale established by the earlier work (A, B volume) was given a good reliability, the validity and the division degree.2 for the clinical evaluation of the elderly patients, with A and B volumes. The discriminant function model, divided into discriminant index, can preliminarily distinguish the degree of cognitive impairment in the elderly patients with cognitive impairment, and has a good accuracy rate of.3. Through further improvement, the scale will be used as a practical means in the clinical diagnosis of dementia patients, and the quantitative evaluation of Chinese medicine for the treatment of dementia. The curative effect provides a new basis.
