Description of intervention(s) / exposure
Te Ara Waiora-Implementing HPV primary testing to prevent cervical cancer in NZ- Te Tai Tokerau : A non-inferiority trial
The primary aim of this project is to test whether the universal offer of HPV self- test to all women is non-inferior to the cervical screening coverage in the current cytology cervical screening program. The intervention is therefore the offer of an HPV self-test. Clinics will be randomly selected to be implementation clinics ( i.e offer of HPV self-test) or comparison clinics ( ie offer of routine standard are - cervical smear for cytology) and screening uptake over 2 years recruitment will be compared.

Posters and flyers with self-test HPV information specifically designed for this study will be displayed in implementation clinics. There is written and verbal information specifically designed for this study, supplied to the women to explain the HPV tests and to explain how to take the swab. Women will be able to take the swab in the clinic . In some circumstances the woman may be visited at home by a health worker and will be able to take the swab at home. The time needed to take the swab if it is self collected is around 1 minute.
Women will be contacted if they are due their cervical smear in the usual way (phone, letter, text) , overdue women ( over due a smear is defined as 4 or more years since last smear) will be contacted in the usual way to explain the HPV tests and women who are due or overdue will be approached opportunistically if they attend the clinic for another reason.

Clinicians (nurses, doctors) and kaiawhina ( community health workers) in the primary care practices will deliver the intervention with prior training. These clinicians and community health workers are the womens' usual primary care givers.
The offer of the HPV self-test swab will be delivered face to face and provided individually.
The offer of HPV tests will be made once to women over the two years of recruitment if they accept the offer. If they don't accept the offer, several attempts may be made over the two years of recruitment, usually every 3 months up to 6 attempts or more.
The offer of the HPV self-test swab will be made in the clinic or in the participant's home if visited by the community health worker or in a community centre.
It is anticipated that most women will take the swab themselves but there may be women who choose to have it taken by their clinician in the clinic.
Intervention adherence will be measured as this is the primary outcome - the screening coverage compared with comparison clinics.

Efficacy
Statistical methods / analysis
The NSCP coverage report from December 2019 for the Northland DHB shows that approximately 72.5% of women (33,403/46,090) aged 25-69 were screened over a period of 3 years. This corresponds to a two-year screening coverage of 48.3%. A total of eight practices and 6,400 women (four practices offering HPV-self-testing universally over a two-year period to approximately 3,200 women, and four practices providing routine clinical care data for approximately 3,200 women about cervical cytology uptake) will give 80% power at a one-sided significance level of 2.5% to detect a non-inferiority margin of 10% between the two groups (i.e. the screening rates at participating practices will be no worse than 10% less than the screening rate obtained from the comparative data). This margin of error was chosen as we believe it is the smallest value that is clinically relevant. For this sample size we assumed a two-year screening rate of 48.3% in the comparative data and 49.3% in the participating practices, and an average practice size of 800 participants and intra-cluster correlation coefficient of 0.01.

Reason for early stopping/withdrawal
Other reasons/comments
Other reasons
target sample size had been reached with revised sample size calculation
new National Cervical Screening Programme was due to start July 2023 ( actually started September 2023) with offer of HPV self-test to all participants therefore our study had to be stopped early as our control group would have been offered an inferior test ( i.e cytology).
