    Objective: To find out the colposcopy outcomes for women aged 20-24, as this group is now missed in the new cervical screening programme. It would be a concern if women with CIN3 or invasive cancer will wait up to 5 years for screening. We want to know if Maori would be disproportionately affected and if other colposcopy outcomes were equitable between Maori and non-Maori. 

    Design: Retrospective analysis of existing data was used to look at outcomes prior to the change to the screening programme.
     
    Method: There were 369 referrals to the Northland District Health Board colposcopy service with high-grade smears (HSIL or ASC-H) from July 2015-September 2018. We looked up all clinic letters for outcomes such as treatment received and final histology, then analysed with age and ethnicity. 

    Results: No invasive cancers were found at 20-24 but 27.7% who were referred to colposcopy for a high-grade smear had CIN3. Of these, 38% were aged 22 or below and they comprise 11% of women aged 20-24 who were referred. 

    Conclusions: There are women aged 20-22 with CIN3 that would have waited 3-5 years for their first smear under the new scheme. We need more information on the rate of progression of CIN3 in this group. It will be interesting to see if there will be any increase in invasive cancers when women first present for a smear at 25. Outcomes for Maori were similar once referred to colposcopy, but we know Maori are less likely to have smears1 and twice as likely to get cervical cancer2.
