Study title acronymthe PATHFINDER study
Study typeObservational study
Brief description of the studyThis project will evaluate the utilization, adherence, efficacy, and safety of disease modifying antirheumatic drugs employed for the management of rheumatoid arthritis in the Tuscan population by means of real world data. This research will identify patterns of utilization of rheumatoid arthritis treatments and their predictors, and it will explore the relationship of these trajectories with endpoints of effectiveness and safety.

11. Scope of the study
What is the scope of the study?
Drug utilisation study
Effectiveness evaluation
safety evaluation
Primary scope : Drug utilisation study
12. Main objective(s)
What is the main objective of the study?
This research will identify patterns of utilization of rheumatoid arthritis treatments and their predictors, and it will explore the relationship of these trajectories with endpoints of effectiveness and safety.
Are there primary outcomes?Yes
We will identify trajectories of utilization of bDMARD and tsDMARD over the time of follow-up (3 years). Trajectories will be identified by using trajectory model approach; patients will be classified according to their most likely pattern of adherence (i.e. the trajectory that the patient has the highest probability of belonging to). We will test several variables as predictors.
Are there secondary outcomes?Yes
a) Validate the selected RA patients
b) Investigate effectiveness over the "off treatment" and "on treatment" periods
c) Evaluate the occurrence of ED admission/hospitalization over the "off treatment" and "on treatment" periods
d) Assess the occurrence of ED admission/hospitalization related to trajectories
13. Study design
What is the design of the study?
Cohort study
Drug utilisation study
14. Follow-up of patients
Will patients be followed up?Yes
Please describe duration of follow up
Patients will be followed up for at least 3 years
15. Data analysis plan
Please provide a brief summary of the analysis method
Validation analysis: sensitivity, specificity, positive and negative predictive value.
Drug-utilization analyses: trajectory model approach.
Effectiveness: descriptive analysis.
Safety analyses: proportion and time free from events.
