3. Age 18 or older at index date

For indicated subcohort: Evidence of RA, PsA, UC diagnosis withing baseline period prior to index date.
For non-indicated subcohort: No evidence of RA, PsA, UC diagnosis withing baseline period prior to index date.

Exclusion criteria:
1. There are no exclusion criteria for this study.

Study design details

Main study objective

What proportions of SARS-CoV-2 diagnosed patients have RA, PsA, or UC or not and what is risk of serious clinical manifestations & outcomes of interest in these subcohorts? What is the proportion treated at baseline with the following systemic therapies: tofacitinib, JAK inhibitors, TNFi, non TNFi, and csDMARD & what is risk of serious clinical manifestations and outcomes by treatment strata?

Outcomes

Determine the proportions of patients with a diagnosis of RA, PsA, & UC, describe baseline demographic characteristics, treatment history and comorbidities, estimate proportion experiencing serious clinical manifestations and outcomes of interest, determine the proportions of patients treated with the following systemic therapies at baseline: tofacitinib, JAK inhibitors, TNFi, non-TNFi & csDMARD.

Data analysis plan

After selection of the study population, summary statistics of baseline variables will be determined for the baseline period. The index date for each patient is defined as the first date that the study inclusion criteria are satisfied. Baseline variables will be summarized as appropriate for categorical and continuous variables with 95% CI provided to show precision of the estimate. Among patients who are included in the study, outcomes will be included that occur during the risk window from index date until the first of death (based on discharge status), 3 months post SARS CoV 2 diagnosis, or end of study period/datacut. The endpoints of interest within each indication, non indicated subcohort and indication/treatment combination will be summarized as appropriate for categorical and continuous variables with 95% CI provided to show precision of the estimate.
