Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The study uses a parallel group comparison design, where usual standard care (control group) or the intervention (HPV self-testing program) will be allocated by primary health care clinic. Inclusion criteria: Maori women who have not had a cervical smear screen in the last 4 years.
Brief title
Offer of self -testing HPV swab to under-screened Maori women

1) Educational Intervention for clinicians and community workers
Materials - Educational material (written/presentation/teaching sessions) given to doctors, nurses, community workers by experts in HPV from research team
Who will deliver intervention - Research team (Professor oncological gynaecology, professor Obstetrics and Gynaecology, sexual health physician/ senior research fellow, family physician/ researcher with expertise in women’s health) will provide educational material and sessions for nurse, doctors and community workers
Mode of delivery - Educational sessions to clinicians will be offered to groups of clinicians from intervention primary care practices in small tutorial setting
Number of times intervention offered - Education sessions will be offered twice to groups of clinicians over 3 months - 2 x 1 hour sessions
Location- Education sessions will be offered in primary care setting/clinic/local community hall

2) Intervention for participants – under-screened Maori women offered self –taken vaginal swab for HPV

Materials - Instructions and diagrams for women being offered HPV self-testing will be co-designed by research team plus input from primary health clinicians, community workers and the women themselves (focus groups) ( draft HPV information and consent is attached to ANZCTR registration form)

Procedures -Women will receive verbal, written and /or pictorial instructions from a doctor, nurse or kaiawhina (community health worker) about how to perform the HPV self-test, a self-collected vaginal sample. Women will self-collect a vaginal sample using a swab. The instructions will detail how to insert the swab into the vagina and place it into a collection container that has been labelled by the healthcare worker with the name, date of birth and unique NHI (National Health Index) number. Specimens are transported at room temperature to local Laboratories, who have agreed to handle the transportation of the samples, with their daily shipments, to national central Laboratories. HPV genotyping will be carried out using Real-time High Risk HPV assay validated for the use of dry swabs. This distinguishes HPV-16 and HPV-18 from other high-risk types and from negative samples.

Who will deliver intervention – the (participants) woman’s usual primary care clinician (family doctor or nurse) or community health worker will deliver the information to participants

Mode of delivery - HPV swab testing will be offered by doctor, nurse or community worker, face-to-face individually

HPV self-testing will be offered between 1 - 5 times over one year to under-screened Maori women

Location- HPV self- testing will be offered in patients home, community venues such as local meeting houses (Maraes) if facilities allow, primary care clinic

Results – results of self- testing for HPV will be given by the woman’s usual primary care clinician ( doctor or nurse.) This can be done by phone or text if the result is negative or if results positive for high risk HPV an appointment will be made for the woman to obtain result and explanation face to face. Results will be available 7-14 days after test has been taken.
Results will also be entered into the National Screening Unit data base (as per usual cervical smear results). This process has been discussed with the screening unit CEO and clinician in charge of cervical screening database.
Any positive result will be followed up and referred for colposcopy by the woman’s usual primary care clinician.

Our study site is Northland where Maori women have almost twice the incidence of cervical cancer compared to non-Maori but almost four times the mortality. In Northland, cervical screening for Maori is approximately 66%. Women fulfilling inclusion criteria will be identified by primary care and matched with the National Screening Unit (NSU) on NHI to confirm screening history. All primary care clinics in the geographical area will be approached and recruited and randomised to intervention or control (usual care). We will recruit until target met.

Prevention
Comparator / control treatment
The study uses a parallel group comparison design, where the control group is primary health care clinic offering usual standard care in the offer of cervical screening to Maori women who are under-screened ( cervical smear > 4 years ago). Once the study is completed and if successful, the four clinics used initially for control (usual standard care) comparisons will be offered access to the HPV self-testing program. 'Usual care' is offer of appointment for cervical smear by letter or phone call to women who have not had a cervical smear for 4 or more years.

Outcomes
Primary outcome [1] 302847 0
Primary outcome: Rate of HPV self-testing in intervention practices compared to rate of cervical smear uptake in control practices.
Outcome assessed by data linkage to primary care clinic records, laboratory results data and data from National Screening Unit NSU.
Timepoint [1] 302847 0

Study design
Purpose of the study
Prevention
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
primary care clinics will be randomised to intervention and control. All women who attend an intervention clinic receive the intervention, All women who attend the control clinic will receive the control (usual care).
Allocation will be blocked (block size 4) using a random number generator, and based at a central administration site (University of Otago, Wellington). Since the clinic will be (randomly) allocated before individual patient eligibility is determined, it is not possible to blind the participant or the health care team to treatment allocation.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
A random number generator ( randomisation.com) will determine the treatment intervention allocation of the clinics.
Masking / blinding

Efficacy
Statistical methods / analysis
Four clinics will be randomly allocated to the intervention and four clinics to usual care. On average, there will be 100 unscreened Maori women per clinic to give 400 per treatment arm. At January 2020 the proportion screened in each arm will be compared( primary outcome) Four hundred/group will provide 85% power to detect a difference between 30-45% based on an estimated ICC of 0.05-0.1. Multivariate logistic regression with a random effect of clinic will compare screening rates while adjusting for co-variates.
