Brief summary

This retrospective audit will investigate if young people who are homeless or at risk of homelessness in Melbourne were up-to-date with routine childhood and adolescent vaccines on first encounter with a nurse-led primary health clinic (the Young People's Health Service), and if they commenced and completed immunisation catch-up plans following referral to the Young People's Health Service immunisation nurse. The purpose of the proposed study is to establish baseline immunisation coverage within the targeted population, then to explore the impact of an immunisation nurse role on immunisation coverage in a population of young people aged 15-24 years who are experiencing or at risk of homelessness. The Young People's Health Service is a program of the Royal Children's Hospital Department of Adolescent Medicine. The data collected will be sourced solely from the Royal Children's Hospital Electronic Medical Records.

The percentage of the young people in the population who are up-to-date for their age with each vaccine will be described.
Proportion of participants referred to the Young People's Health Service immunisation nurse who were are at increased risk of vaccine-preventable diseases.All available medical records for the participant on the Royal Children's Hospital Electronic Medical Records regardless of time frameWhere available, data collected from the Electronic Medical Records (EMR) will include risk factors for vaccine-preventable diseases and relevant social determinants of health based on the Australian Institute of Health and Welfare, the Australian Government Department of Health and the National Centre for Immunisation Research and Surveillance publications.
