Opportunistic childhood vaccinations in emergency--are we really missing anyone?

Summary Objectives Every health service presentation of a child should be considered an opportunity to ensure optimal immunisation. Measures to limit missed opportunities for vaccination in local emergency departments (ED) should reflect the scale of opportunity and parental support of immunisation service delivery strategies. Methods The vaccination status of every child aged less than seven years that presented to a tertiary hospital ED over a three month period was identified using the Australian Childhood Immunisation Register (ACIR). Contra-indications to vaccination were determined from medical records. A telephone survey or posted survey was conducted with parents of eligible children to confirm ACIR status and whether they would have consented to receiving vaccinations during their presentation. ED records were reviewed for vaccination history recording and ACIR records were reviewed, after interview, to confirm parental reports that initial ACIR status was incorrect. Results Nine per cent (215/2399) of children were identified as incompletely vaccinated according to ACIR. Forty-seven children were excluded. Of the remaining 168 children, 95 parents (57%) participated. Thirty-eight children had no contra-indications and their parents would have consented to vaccination during their ED presentation. The vaccination status of 82% (78/95) was recorded in ED records, but was incorrect in 35 cases. Forty parents indicated that the ACIR record was incorrect and this was confirmed in 36 cases (90%). Conclusions There were missed opportunities to vaccinate a small proportion of children in ED. Parents provided a more accurate timely history of immunisation status than ACIR and thus ED staff should ensure that parents are always asked whether their child is fully vaccinated and provide or encourage vaccination.
