Relationship between parent held child records for immunisations, parental recall and health service.

Abstract

Parent held child records (PHCR) were introduced in Ireland in 2008. This study investigated the relationship between the PHCR, parental recall and regional Health Service Executive (HSE) records for immunisation uptake. It used the Lifeways cohort study of 1070 singleton children to compare immunisation data from PHCR at one year, parental recall at five years and information from the HSE. When compared to HSE records, full recording of primary immunisations in the PHCR was reported for 695 of 749 (92.8%) children. Parental recall was correct for 520 of 538 (96.7%) children. Of the 307 completed PHCRs, 207 (75.9%) agreed with the HSE records. Agreement between the three sources for primary immunisations was 74-93% but was not statistically significant. Agreement was 91% (p < 0.001) for measles, mumps and rubella (MMR) vaccines between parental recall and HSE records. PHCRs underestimated and parental recall overestimated immunisation status when compared with HSE records.
