JF BMJ Health & Care Informatics JO BMJ Health Care Inform FD BMJ Publishing Group Ltd SP e100486 DO 10.1136/bmjhci-2021-100486 VO 28 IS 1 A1 Rachel Isba A1 Nigel Davies A1 Jo Knight YR 2021 UL http://informatics.bmj.com/content/28/1/e100486.abstract AB Vaccination is a global success story, yet UK coverage remains undertarget for a number of diseases. The paediatric emergency department (PED) offers the potential for opportunistic vaccination interventions.Objectives To map the Greater Manchester (GM) Child Health Information System network to see if it was a viable source of vaccination data for clinicians working in the PED as a case study.Methods Postprimary care vaccination management systems for GM were visualised using a systems mapping approach, with data obtained from the Office for National Statistics and commissioners in the GM Health and Social Care Partnership.Results Once vaccination data left primary care, it passed through 1 of 10 local child health information services (CHISs), using an assortment of different information technology systems, after which it shed individual identifiers and was aggregated within national systems. None of the existing GM CHISs were accessible to PED practitioners.Conclusion More work needs to be done to explore possible alternative sources of accurate vaccination data during a PED consultation.Data sharing is not applicable as no datasets were generated and/or analysed for this study.
