The potential for centralized reminder/recall to increase immunization rates: A national survey of immunization...

Little is known about Immunization Information System (IIS) attitudes and experiences using Centralized IIS-based Reminder/Recall (CI-R/R), an effective approach to increasing immunization rates. To describe among IIS managers as it relates to CI-R/R: 1) past experiences and future plans conducting it; 2) attitudes and barriers, 3) IIS capabilities and polices that influence, and 4) factors that differentiate IIS who have and have not conducted CI-R/R. Electronic Surveys were sent to all IIS managers in July 2018 using a member listserve. Fifty-seven of 62 IIS programs contacted (92%) responded. The majority (61%) had ever conducted CI-R/R; 34% reported they were "very likely" to conduct CI-R/R within 6 months. The majority (64%) were in favor of CI-R/R. Barriers included lack of staff (78%), competing demands (76%), and cost (63%). Thirty percent reported receiving a ≥75% of immunization data via real-time electronic interfaces (HL7). Overall, 49% and 24% of jurisdictions had mandatory immunization reporting from private and public health entities for childhood and adult immunizations, respectively. Differences between IIS that ever and never performed CI-R/R, respectively, included: mandatory reporting from private and public entities for children (65% v 27%, p = 0.006), having a legal mandate for CI-R/R (50% v 19%, p = 0.02), less likely to prefer practice-based R/R to CI-R/R (68% v. 91%, p = 0.04), and not reporting having too many competing demands (29% v 67%, p = 0.007). Most IIS have conducted CI-R/R and have positive attitudes towards it. Given it effectiveness and low cost, efforts to sustain it should be considered.
