简要总结
This study has one primary objective and two secondary objectives, with an overall goal of understanding barriers to vaccination and vaccination confidence, so that effective interventional strategies can be further developed and tested to improve vaccination outcomes in a community healthcare setting.
详细描述
The study will use a mixed methods approach, combining focus group discussion, virtual interviews with healthcare professionals, cross-sectional survey on vaccination attitude, and clinic-based intervention with a cluster randomized controlled trial design for the quantitative stage. They study will also follow up patients with interviews after the quantitative stage completes.

入选标准
- •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
排除标准
- •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.
结局指标
主要结局
Vaccine confidence scale(s)
时间窗: 6 months over vaccination attitude for each subpopulation
Vaccination attitude (confidence or hesitancy) measured by the following: For caregivers of 19-35 months children: Parent Attitudes about Childhood Vaccines Survey - Short Form (PACV-SF) and Emory Vaccine Confidence Index (EVCI); For caregivers of pediatric patients 3 years or older: Vaccination Confidence Scale (VCS) and EVCI; For adult patients: Vaccination Attitudes Examination Scale (VAX); For clinical workers/health professionals: VAX.
次要结局
- Vaccination rates(6 months over vaccination attitude for each subpopulation)
- Missed opportunities for vaccination (MOVs)(6 months over vaccination attitude for each subpopulation)
