Background: A software based tool has been developed (Optem) to allow automatize the recommendations of the Canadian Multiple Sclerosis Working Group for optimizing MS treatment in order to avoid subjective interpretation. Methods: Treatment Optimization Recommendations (TORs) were applied to our database of patients treated with IFN beta 1a IM. Patient data were assessed during year 1 for disease activity, and patients were assigned to 2 groups according to TOR: change treatment (CH) and no change treatment (NCH). These assessments were then compared to observed clinical outcomes for disease activity over the following years. Results: We have data on 55 patients. The change treatment status was assigned to 22 patients, and no change treatment to 33 patients. The estimated sensitivity and specificity according to last visit status were 73.9% and 84.4%. During the following years, the Relapse Rate was always higher in the change treatment group than in the no change treatment group (5 y; CH: 0.7, NCH: 0.07; p < 0.001, 12 m - last visit; CH: 0.536, NCH: 0.34). We obtained the same results with the EDSS (4 y; CH: 3.53, NCH: 2.55, annual progression rate in 12 m - last visit; CH: 0.29, NCH: 0.13). Conclusion: Applying TOR at the first year of therapy allowed accurate prediction of continued disease activity in relapses and disability progression.
