| Group | Title | Description | With the outcome | Analysed | ClinicalTrials.gov code | Source |
|---|---|---|---|---|---|---|
| Group 1 | Outreach | The intervention consisted of a tiered protocol, with each step being more intensive and targeting a progressively smaller proportion of adolescents who remained behind in immunizations. The intervention was delivered by trained patient immunization navigators.~Step 1- Patient tracking: We used a web-based database to track the adolescents in the intervention group, record immunizations and preventive visits, and document tasks they performed.~Step 2: Reminders and recall: The navigators performed reminder/recall for adolescents who were eligible for either a vaccination or a preventive care visit. They attempted to contact families by telephone and mail.~Step 3: Home visits: If adolescents remained unvaccinated despite the above steps, the navigators performed a home visit to further assess barriers, promote the importance of preventive care, and encourage families to make appointments. | 2,609 | 3,839 | OG000 | ClinicalTrials.gov |
| Group 2 | Standard of Care | Control subjects received standard of care. All practices routinely sent letter or telephone reminders to families who had upcoming scheduled visits, but none used active reminder/recall based on vaccinations. | 2,045 | 3,707 | OG001 | ClinicalTrials.gov |
