Study description

This is a 6-year active surveillance, secondary data collection study of adult UC patients aged ≥18 years using data in SWIBREG linked via unique patient identifiers to existing nationwide health registers in Sweden. Due to a one-year lag associated with linking SWIBREG to other Swedish national registers (essential for the assessment of safety events associated with UC therapy), and to allow for a minimum follow-up duration of 12 months, UC patients meeting the study entry criteria through 31 March 2024 will be included in the analysis, follow-up of patients for the study will end 31 March 2025, and end of data collection will be 31 March 2026 when the full dataset with completed linkages will be available for analysis. Incidence rates and associated 95% confidence intervals (CIs) of the safety events of interest will be calculated in all four cohorts. Data capture and follow up methods are the same for the tofacitinib treatment cohort and the 3 comparator treatment cohorts within the Swedish Registers. For both primary and secondary safety events of interest, comparative analyses will be conducted as feasible.
