- Individuals with at least 2 health care encounters with assigned ICD-10 codes for RA or IBD (UC or CD) in the year prior to and including the index date will be identified from the EHR, as specified below. This algorithm was selected based on the literature and KPSC chart review indicated a high positive predictive value of this approach.
- Rheumatoid arthritis ICD-10 Codes
- For both VE and safety objectives, individuals who receive a second dose less than 4 weeks (i.e., 28 days) after the first dose will be excluded, since Advisory Committee on Immunization Practices (ACIP) guidelines state that these individuals must repeat the second dose.
- For the VE objectives, individuals with an HZ diagnosis in the 6 months prior to the index date will be excluded to ensure that HZ diagnoses after the index date are new, rather than carried over from HZ episodes prior to the index date.
- M05.*
- M06.*
- K50.*
- K51.*
- Aged ≥18 years at index date
- At least 1-year of continuous KPSC membership prior to the index date and until 31 days after index date (allowing for a 31-day gap in membership) Safety
- Received ≥1 dose of RZV
- Aged ≥18 years at date of first RZV dose
- At least 1-year continuous KPSC membership prior to date of first RZV dose (allowing for a 31 day gap in membership)
Individuals with at least 2 health care encounters with assigned ICD-10 codes for RA or IBD (UC or CD) in the year prior to and including the index date will be identified from the EHR, as specified below. This algorithm was selected based on the literature and KPSC chart review indicated a high positive predictive value of this approach. Rheumatoid arthritis ICD-10 Codes
Rheumatoid arthritis with rheumatoid factor
Other rheumatoid arthritis Crohn’s disease ICD-10 Codes
Crohn's disease Ulcerative colitis ICD-10 Codes
Ulcerative colitis Individuals will be included in the study if they meet the following criteria: VE
- For the VE objectives, individuals with an HZ diagnosis in the 6 months prior to the index date will be excluded to ensure that HZ diagnoses after the index date are new, rather than carried over from HZ episodes prior to the index date.
- Individuals with HZ occurring within 30 days after the index date for both vaccinated and unvaccinated groups will also be excluded since it is unclear if the HZ episode began before or after the index date and whether the length of time since vaccination (for RZV vaccinated individuals) is long enough to allow for sufficient development of immunity.
- Individuals with receipt of zoster vaccine within 30 days after index date will be excluded.
- Individuals with a death date within 30 days after index date will be excluded.
For both VE and safety objectives, individuals who receive a second dose less than 4 weeks (i.e., 28 days) after the first dose will be excluded, since Advisory Committee on Immunization Practices (ACIP) guidelines state that these individuals must repeat the second dose.
