Brief Summary

This study aims to evaluate the comparative risk of dementia/Alzheimer's disease onset between patients treated with medications that target specific metabolic pathways and patients treated with alternative medications for the same indication.

Conditions

Rheumatoid Arthritis

Outcome Measures

Primary Outcomes (1)

• Time to dementia onset

  Time to dementia onset, i.e., Alzheimer's disease, vascular dementia, senile, presenile, or unspecified dementia, or dementia in other diseases classified elsewhere. Please refer to uploaded protocol for full definition due to size limitations.

  Through study completion (a median of 250 days)

Secondary Outcomes (1)

• Time to Alzheimer's disease onset

  Through study completion (a median of 250 days)

Study Arms (2)

Tocilizumab

Reference group

Drug: Tocilizumab

Abatacept

Exposure group

Drug: Abatacept

Interventions

Tocilizumab DRUG

Tocilizumab claim is used as the reference group.

Eligibility Criteria

• Age: 18 Years+
• Sex: all
• Healthy Volunteers: Yes
• Age Groups: Adult (18-64), Older Adult (65+)
• Sampling Method: Non-Probability Sample

Study Population

This study will involve a new user, parallel group, cohort study design comparing tocilizumab to abatacept. The patients will be required to have continuous enrollment during the baseline period of 355 days before initiation of tocilizumab or abatacept (cohort entry date). Follow-up for the outcome (incident dementia), begins the day after drug initiation for analyses 1, 3, and 4 and 180 days after drug initiation for analysis 2.

You may qualify if:

• \. No prior use of tocilizumab or abatacept anytime prior to cohort entry date
• \. Enrollment in Medicare Part A, B, and D with no HMO coverage for 365 days prior to and including cohort entry date

You may not qualify if:

• \. Prior history of dementia measured anytime prior to cohort entry date
• \. No prior history of rheumatoid arthritis recorded in the 365 days prior to cohort entry date
• \. Prior history of nursing home admission in the 365 days prior to the cohort entry date
