RESUMEN
Objective:To design an oral methotrexate auxiliary device and explore the effect of methotrexate in patients with rheumatoid arthritis.Methods:Totally 30 patients with rheumatoid arthritis were selected and observed continuously for 12 months, from January to June in 2021, in the Affiliated Changzhou No. 2 People ′s Hospital of Naijing Medical University. The subjects took the medicine routinely in the first 6 months after entering the group, and the methotrexate oral drug assistant device was given in the latter 6 months to remind them to take the medicine correctly. Medication administration of patients before and after using the auxiliary device was compared, and the evaluation indexes such as disease activity, medication compliance and anxiety were observed. Results:Without the auxiliary device, there were 14 cases (46.67%) of medication error, 13 cases (43.33%) of medication time error, 9 cases (30.00%) of missed administration, while after the use of the auxiliary device, there were 4 cases (13.33%) of medication error, 2 cases (6.67%) of medication time error and 2 cases (6.67%) of missed administration, and the differences were statistically significant ( χ2=8.10, 9.09, 5.14, all P<0.05). Moreover, before using the auxiliary device, the scores of disease activity and medication compliance were 3.92 ± 0.95, 84.97 ± 6.49, respectively, while with the help of the auxiliary device, those scores changed to 3.29 ± 0.83, 92.40 ± 4.17 respectively. All the differences were statistically significant ( t=10.06, -10.37, both P<0.01). 16 cases (53.33%) were anxious after using the assistive device, which was also better than 26 cases (86.67%) before using the device. The difference was statistically significant ( χ2=8.10, P<0.01) . Conclusions:Oral administration aid for methotrexate can help rheumatoid arthritis patients to take methotrexate correctly and safely, reducing disease activity and anxiety, improving drug compliance. It is worthy to clinical promotion.
RESUMEN
Objective:To investigate the Chinese version of rheumatoid arthritis stigma scale (ISMI-RA) and test its reliability and validity.Methods:The English version of ISMI-RA was translated into Chinese, translated back and culturally adapted in strictly accordance with the Brislin translation model. A total of 20 patients were selected for preliminary investigation and some items were revised to create the Chinese version of ISMI-RA. From April 2020 to April 2021, 258 patients with rheumatoid arthritis were investigated by convenience sampling method, Pearson correlation intraclass correlation coefficient (ICC) coefficient and Cronbach's α coefficient were used to evaluate the test-retest reliability and internal consistency of the scale. The stigma scale for chronic illness-8 was used as the standard, and the correlation coefficient was calculated to verify the criterion validity. Confirmatory factor analysis was used to evaluate the construct validity of the scale.Results:The internal consistency Cronbach's α coefficient was 0.86, the Cronbach's α coefficient of each dimension was 0.34-0.93, and Pearson correlation analysis of retest reliability showed that it was 0.94. The Cronbach's α coefficient of stigma resistance subscale was as low as 0.34, and the Cronbach's α coefficient of stigma resistance subscale was 0.90 after removal. The retest reliability was 0.98. The criterion coefficient between this scale and the stigma scale for chronic illness-8 was 0.73 ( P<0.001), and the criterion coefficient of the subscales were 0.52-0.71. The theoretical factor structure of ISMI-RA that is composed of five factors showed suboptimal model fitting [root-mean-square error of approximation ( RMSEA)=0.10, Tucker-Lewis index ( TLI)=0.88, comparative fit index (CFI)=0.89)], and the model fitting effect was better after removing the dimension of resistance to stigma and three items ( RMSEA=0.09, CFI=0.94, TLI=0.93). Conclusion:The Chinese version of ISMI-RA has good reliability and validity, and can be used as an evaluation tool to measure the level of stigma in rheumatoid arthritis patients, and to provide a basis for clinical development of intervention programs to facilitating the rehabilitation process.
RESUMEN
Objective To translate and revise the form of rheumatoid arthritis (RA) self-efficacy scale (RASE),and evaluate the revised scale.Methods Totally 101 patients with RA in one hospital were selected for investigation.Through the translation-back to the source scale and the cultural adjustment,the Chinese version of RASE (C-RASE) was formed.Exploratory factor analysis was conducted to acquire the construct validity while the Pearson correlation analysis was used to obtain the test-retest reliability.Results Factor analysis was carried out on 28 items,and the loading was 0.496,0.490,0.482 and 0.493 of item 5,and item 15 on two factors respectively.Exploratory factor analysis was conducted secondarily after deleting items of 5,15,and 17,considering the item contents,and 9 factors were extracted,respectively named for exercise,comprehensive treatment,relaxation,activity,sleep,social relationship,fatigue,cognition and active planning,which could explain 68.36％ of total variation;aud the correlation coefficient between each dimension and total table ranged 0.344 to 0.679 (P＜0.01);The Cronbach's alpha coefficient of the C-RASE was 0.751,and the retest reliability was 0.731.After deleting their own items,the Cronbach's alpha value range was 0.730 to 0.756.Conclusion C-RASE has sound reliability and validity and could provides a measurement of the self-efficacy among rheumatoid arthritis patients.
