Reminder-recall interventions have improved immunization rates in numerous studies.
To evaluate the impact of large-scale, registry-based reminder-recall interventions on low immunization rates in an inner-city population.
Randomized, controlled, effectiveness trial.
Fulton County, Georgia.
A total of 3050 children (76% black, 14% Hispanic, 7% white, and 3% other or unknown; median age, 9 months; range, 1-14 months) identified in an immunization registry as receiving health care in the public sector.
Each child was randomly assigned to 1 of 4 groups: control (usual care), autodialer (automated telephone or mail reminder recall), outreach (in-person telephone, mail, or home visit recall), and combination (autodialer with outreach backup). Interventions continued until the child reached 24 months of age.
Completion by the age of 24 months of the 4-3-1-3 vaccination series based on intention-to-treat analysis.
A total of 260 (34%) of the 763 patients in the control group, 306 (40%) of the 763 in the autodialer group, 284 (37%) of the 760 in the outreach group, and 293 (38%) of 764 in the combination group completed the vaccination series.
Large-scale, registry-based reminder-recall interventions produced only small improvements in low immunization rates of an inner-city population.
在众多研究中，提醒-召回干预措施提高了免疫接种率。
评估基于登记系统的大规模提醒-召回干预措施对市中心城区低免疫接种率人群的影响。
随机对照有效性试验。
佐治亚州富尔顿县。
在免疫登记系统中确定的3050名儿童（76%为黑人，14%为西班牙裔，7%为白人，3%为其他或不明种族；中位年龄9个月；范围1 - 14个月），这些儿童在公共部门接受医疗保健。
每个儿童被随机分配到4组中的1组：对照组（常规护理）、自动拨号组（自动电话或邮件提醒-召回）、外展组（亲自电话、邮件或家访召回）和联合组（自动拨号并辅以外展）。干预措施持续到儿童满24个月。
基于意向性分析，24个月龄时完成4-3-1-3疫苗接种系列。
对照组763名患者中有260名（34%）、自动拨号组763名中有306名（40%）、外展组760名中有284名（37%）、联合组764名中有293名（38%）完成了疫苗接种系列。
基于登记系统的大规模提醒-召回干预措施仅使市中心城区低免疫接种率人群的免疫接种率有小幅提高。
