Eligibility | Qualitative study standards: Inclusion Criteria: - having used MultiCare's services in the past 12 months or whose minor child(ren) has/have used MultiCare's services in the past 12 months, and who have been involved in the child(ren)'s immunization decision-making as a caregiver - current residential location in Washington State - willing to participate Exclusion Criteria: - terminal disease (to be decided) - cognitive impairment - main immune deficiency conditions Quantitative study standards: We will randomly (and) equally select clinics from 1) Puget Sound and 2) Eastern Washington areas. Since the intervention is on facility level (group intervention), instead of at patient level, blinding will also be impractical. We plan to use stratified random allocation within the pediatric (n1 = 2) or adult stratum (n2 = 4), to decide which sites will get the intervention. |
