AbstractObjective:To assess predictors of achievement of 80% Medication Possession Ratio (MPR) in patients receiving manufacturer-provided self-management services for relapsing-remitting multiple sclerosis (RRMS) patients taking glatiramer acetate (Copaxone).Methods:De-identified patient records were selected for study inclusion if patients had been (1) continuously enrolled in one or more aspects of the self-management program for a minimum of 24 months and had adherence measured by MPR between the values of zero and one. Baseline patient univariate measures were assessed using chi-squared statistics for categorical variables and Analysis of Variance (ANOVA) for continuous variables. Bivariate logistic regression models were used to assess predictors of 80% MPR.Results:A total of 5825 patients met the study inclusion criteria. About 70% of patients received manufacturer-provided injection training and 75% were eligible for, and utilized, copayment assistance; 74.3% of patients accessing sponsor provided...
