简要总结
Under-immunization rates for childhood immunizations in the United States range from 8-20%. Previous studies have demonstrated that pediatric patients are most likely to be under-immunized for seasonal immunizations. The aim of this study is to explore the factors and facilitators contributing to measles immunization hesitancy. A secondary aim is to explore the impact of hypothetical contexts on measles immunization hesitancy. The results of this study may identify potential disparities in measles immunization coverage and potential solutions for addressing those disparities.
详细描述
SUBJECT POPULATION (WHO, WHAT, WHERE)
Aim 1: Guardians of patients 1 year to 6 years old presenting to the pediatric emergency department between 6/1/2025 and 6/1/2026 will be eligible. It is expected that approximately 800 parental encounters will be enrolled at AMC. Parents of children meeting the above inclusion and exclusion criteria will be approached for consent to participate in the study by convenience sampling weekdays 0900-1700. All consenting guardians will complete a brief survey to assess parental demographics and child immunization history. All participants who identify that a child is under-immunized for measles (i.e., did not receive 1st MMR immunization at 1 year of age OR 2nd MMR immunization at 4 years of age) will go on to complete a comprehensive survey to assess immunization beliefs.
Aim 2: In a private location, research assistants (RA) will randomly sample patients between 1 and 6 years of age in the pediatric ED and approach the patient's caregivers for participation in the survey if eligible. Caregivers will give written consent to participate in the survey. Caregivers will complete the survey in the ED on a private tablet. All guardians who complete the comprehensive survey will be randomized to receive one of four patient-centered immunization messages. The guardian will then be asked again if there is intent to immunize the child against RSV this season and if acceptance of immunization would occur if administered at the current visit.
Patient Sampling The RA will screen patients using convenience sampling methodology.
Patient recruitment, enrollment, and progress through the study Once a patient is screened and determined to be eligible, the RA will review the patient's ED electronic health record (dashboard or face sheet) and record (in a REDCap database) the following de-identified information: race/ethnicity, gender, ESI level, insurance status, and chief complaints.

结局指标
主要结局
Caregiver Measles Vaccination Intent
时间窗: Baseline (during pediatric emergency department visit)
Caregiver intent to vaccinate their child against measles, measured using a single survey item with categorical responses ("yes," "unsure," "probably not," or "definitely not") and reported as the proportion of caregivers classified as intent ("yes") versus non-intent ("unsure," "probably not," or "definitely not") at baseline.
次要结局
- Change in Caregiver Measles Vaccination Intent After Message Exposure(Immediately after provider message exposure during the same emergency department visit)
