Subtheme: Innovation and smart ideas Background In response to the 2019 measles outbreak the Ministry of Health (MoH) initiated a Measles, Mumps, Rubella (MMR) vaccination catch-up campaign for people aged 15-30 years focussing on Maori and Pacific peoples. Initial estimates suggested that only 25% of people in this cohort in Counties Manukau Health DHB area were fully vaccinated for measles. The National Immunisation Register (NIR) has poor data for this cohort however, the primary care record is an alternative source of vaccination record. Aim To improve MMR vaccination coverage data by utilising primary care held vaccination records to assist the MMR catch-up campaign. Methods This project was approved by the regional privacy committee and the Metro Auckland Data Sharing Governance Group. Primary care practice management systems (PMS) MMR vaccination data was sourced via the seven Auckland Primary Healthcare Organisations (PHOs) for people aged 15-30 years and from the NIR, then matched to the PHO enrolled population (Age-sex-register). A grading system was used to categorise data quality and completeness. District health Board patient tables were used to ascertain potential unenrolled population. Results 51.6% of 15-30 year-olds on Metro-Auckland PHO registers have a record of MMR vaccination almost all fully vaccinated. Data is now available on population coverage by ethnicity and mesh block thereby enabling focus of MMR campaign efforts to priority populations. Data has been returned to PHOs, used to add a MMR flag to the COVID Immunisation Register and for a calling campaign through Whakarongorau-Healthline. The data yield is likely to be further improved by implementing data sharing frameworks where there is both precedence and confidence to appropriately share data, and by expanding to include national primary care data. Conclusion Vaccination information held by primary care in Metro-Auckland has substantially improved MMR coverage data for 15-30 year-olds and enabled focussing of efforts for the catch-up campaign.
