Among 19,765 individuals with RA, 44.78% had access to a rheumatologist within one year of diagnosis; 24.91% were retained in care, while only 24.30% were dispensed a DMARD within 30 days, and 32.66% received a DMARD annually for the first 2 years.

Between 2000 and 2023, 289 031 limited and 41 482 persistent uveitis cases were identified, with mean index ages of 56.8 (SD 21.0) and 58.3 (SD 20.3) years, respectively.

A higher proportion of children and youth were identified with limited duration uveitis.

Sex distribution was similar between groups, and 89%-91% of cases resided in urban areas.

Persistent cases also had substantially higher resource utilization than limited uveitis cases.

Within the validation sample, the median age of identified uveitis patients was 55 years, with the majority falling within the 26-64 age group.

Females represented 59.9% of cases.

Family physicians (72.2%) and ophthalmologists (60.6%) were the most common sources of diagnosis documentation, and anterior uveitis was the most prevalent classification (64.0%).

PPV increased with more physician diagnosis codes but was accompanied by decreased sensitivity.
