Objective To verify the accuracy of ARS scale.Methods A cohort study was conducted in 10 counties (city)the in-troduction of the ARS scale from 2013 November to 2014 May (6 months),the registrations were undertake score,and score < 4 were compliance group,more than 4 cent were nonadherence group.Follow-up observation include review at the end of 2nd month after treatment and medicine compliance.Results There was no significant difference in age,gender,nationality and whether the floating population between the compliance group and non compliance group (P >0.05),initial treatment and retreatment was sta-tistically significant (P <0.05).1 824 patients had a mean score of 3.40±1.40,including compliance group mean score was 2.34± 0.73,is not in compliance with group mean score was 4.69±0.81.Mainly concentrated in the 2-5 scores accounted for 86%.The ARS score of 2 at the end of the packet and judge review the results of test,the Kappa coefficient was 0.403 (P <0.05).The sensi-tivity was 71.1%,specificity was 70.2%,the correct index 0.41.Multivariate Logistic and review the compliance of patients re treatment ARS score,at the beginning of the results of regression analysis showed that ARS score,under the same conditions,re-treatment review compliance was initially treated patients with difference (OR=0.41,P <0.05);in the initial treatment and retreat-ment premise under the same circumstances,review of compliance with the ARS score less than 4 points.It′s 5.65 times greater than or equal to 4 points (P <0.05).Conclusion The ARS scale can accurately judge the patient compliance,with high sensitivity and specificity,suitable for application in Guizhou Province,but we should consider other interference factors of promotion.
