Practitioners support and intention to adopt universal access to self-collection in Australia's National Cervical Screening Program.

OBJECTIVE: Primary care practitioners are crucial to engaging people in Australia's national cervical screening program. From July 2022, practitioners have been able to offer all screen-eligible people the choice to collect their own self-collected sample; an option introduced to increase equity. This study explored how practitioners are intending to incorporate universal access to self-collection into their clinical care. METHODS: Semi-structed interviews with 27 general practitioners, nurses, and practice managers from 10 practices in Victoria, Australia conducted between May and August 2022. Interviews were deductively coded, informed by the Consolidated Framework for Implementation Research. The Diffusion of Innovations theory was used to categorise intention to provide self-collection. RESULTS: Participants were supportive of universal access to self-collection, citing benefits for screen-eligible people and that it overcame the limited adaptability of the previous policy. Most participants' practices (n = 7, 70%) had implemented or had plans to offer the option for self-collection to all. Participants deliberating whether to provide universal access to self-collection held concerns about the correct performance of the self-test and the perceived loss of opportunity to perform a pelvic examination. Limited time to change practice-level processes and competing demands within consultations were anticipated as implementation barriers. CONCLUSIONS: The extent to which self-collection can promote equity within the program will be limited without wide-spread adoption by practitioners. Communication and education that addresses concerns of practitioners, along with targeted implementation support, will be critical to ensuring that self-collection can increase participation and Australia's progression towards elimination of cervical cancer.

Participation in the national cervical screening programme among women from New South Wales, Australia, by place of birth and time since immigration: A data linkage analysis using the 45 and up study.

OBJECTIVE: Equitable elimination of cervical cancer in Australia within the next decade will require high National Cervical Screening Program (NCSP) participation by all subgroups of women. The aim of this study was to examine the participation of immigrants compared to Australian-born women. METHODS: Participation in the NCSP (≥1cytology test) over a 3-year (2010-2012) and 5-year (2008-2012) period, by place of birth and time since immigration was examined using individually linked data of 67,350 New South Wales (NSW) women aged ≥45 enrolled in the 45 and Up Study. RESULTS: Three-year cervical screening participation was 77.0% overall. Compared to Australian-born women (77.8%), 3-year participation was lower for women born in New Zealand (adjusted odds ratio 0.77, 95% confidence interval 0.69-0.87), Oceania (0.67, 0.51-0.89), Middle East/North Africa (0.76, 0.60-0.97), South-East Asia (0.72, 0.60-0.87), Chinese Asia (0.82, 0.69-0.97), Japan/South Korea (0.68, 0.50-0.94), and Southern/Central Asia (0.54, 0.43-0.67), but higher for women from Malta (2.85, 1.77-4.58) and South America (1.33, 1.01-1.75). Non-English-speaking-at-home women were less likely to be screened than English-speaking-at-home women (0.85, 0.78-0.93). Participation increased with years lived in Australia but remained lower in immigrant groups compared to Australian-born women, even after ≥20 years living in Australia. Similar results were observed for 5-year participation. CONCLUSIONS: Women born in New Zealand, Oceania, and parts of Asia and the Middle East had lower NCSP participation, which persisted for ≥20 years post-immigration. The NCSP transition to primary HPV screening, and the introduction of the universal self-collection option in 2022, will offer new opportunities for increasing screening participation for these groups.

A Model for Empowering Rural Solutions for Cervical Cancer Prevention (He Tapu Te Whare Tangata): Protocol for a Cluster Randomized Crossover Trial.

BACKGROUND: Maori are the Indigenous people of Aotearoa (New Zealand). Despite global acceptance that cervical cancer is almost entirely preventable through vaccination and screening, wahine Maori (Maori women) are more likely to have cervical cancer and 2.5 times more likely to die from it than non-Maori women. Rural Maori residents diagnosed with cervical cancer have worse outcomes than urban residents. Living in rural Aotearoa means experiencing barriers to appropriate and timely health care, resulting from distance, the lack of community resourcing, and low prioritization of rural needs by the health system and government. These barriers are compounded by the current screening processes and referral pathways that create delays at each step. Screening for high-risk human papillomavirus (hrHPV) and point-of-care (POC) testing are scientific advances used globally to prevent cervical cancer. OBJECTIVE: This study aims to compare acceptability, feasibility, timeliness, referral to, and attendance for colposcopy following hrHPV detection between a community-controlled pathway and standard care. METHODS: This is a cluster randomized crossover trial, with 2 primary care practices (study sites) as clusters. Each site was randomized to implement either pathway 1 or 2, with crossover occurring at 15 months. Pathway 1 (community-controlled pathway) comprises HPV self-testing, 1-hour POC results, face-to-face information, support, and immediate referral to colposcopy for women with a positive test result. Pathway 2 (standard care) comprises HPV self-testing, laboratory analysis, usual results giving, information, support, and standard referral pathways for women with a positive test result. The primary outcome is the proportion of women with hrHPV-positive results having a colposcopy within 20 working days of the HPV test (national performance indicator). Qualitative research will analyze successes and challenges of both pathways from the perspectives of governance groups, clinical staff, women, and their family. This information will directly inform the new National Cervical Screening Program. RESULTS: In the first 15-month period, 743 eligible HPV self-tests were performed: 370 in pathway 1 with POC testing and 373 in pathway 2 with laboratory testing. The positivity rate for hrHPV was 7.3% (54/743). Data collection for the second period, qualitative interviews, and analyses are ongoing. CONCLUSIONS: This Maori-centered study combines quantitative and qualitative research to compare 2 clinical pathways from detection of hrHPV to colposcopy. This protocol draws on rural community practices strengths, successfully engaging Maori from a whanau ora (family wellness) approach including kanohi ki te kanohi (face-to-face), kaiawhina (nonclinical community health workers), and multiple venues for interventions. It will inform the theory and practice of rural models of the use of innovative technology, addressing Maori cervical cancer inequities and facilitating Maori wellness. The findings are anticipated to be applicable to other Indigenous and rural people in high-income countries.

Protocol for the formative phase of a trial (SHE-CAN) to test co-designed implementation strategies for HPV-based cervical screening among vulnerable women in two diverse settings in India.

BACKGROUND: In view of the WHO's call for the elimination of cervical cancer as a public health problem, and current low screening coverage, Indian policy makers need evidence on how to effectively implement cervical screening programmes, ensuring equity in access. Our study will follow the INSPIRE implementation framework to co-design and test HPV-based screening approaches in two states of India with different health system organisation, based on understanding the status of screening as currently implemented, readiness and challenges to transition to HPV-based screening, and preferences of key stakeholders. Here, we describe our protocol for the formative phase of the study (SHE-CAN). METHODS: The study population includes women from vulnerable populations, defined as residents of tribal areas, rural villages, and urban slums, in the states of Mizoram and Tamil Nadu. The baseline assessment will use mixed methods research, with desktop reviews, qualitative studies, and surveys. A capacity assessment survey of screening and treatment facilities will be done, followed by interviews with healthcare providers, programme managers, and community health workers. Interviews will be conducted with previously screened women and focus group discussions with under and never-screened women and community members. Stakeholder workshops will be held in each state to co-design the approaches to delivering HPV-based screening among 30-49-year-old women. DISCUSSION: The quality and outcomes of existing screening services, readiness to transition to HPV-based screening, challenges in providing and participating in the cervical cancer care continuum, and acceptability of screening and treatment approaches will be examined. The knowledge gained about the current system, as well as recognition of actions to be taken, will inform a stakeholder workshop to co-design and evaluate implementation approaches for HPV-based screening through a cluster randomised implementation trial.

'I'm a bit of a champion for it actually': qualitative insights into practitioner-supported self-collection cervical screening among early adopting Victorian practitioners in Australia.

BACKGROUND: Self-collection for cervical screening has been available in the Australian National Cervical Screening Program since 2017 and is now available to all people as an option for cervical screening through a practitioner-supported model. Documenting early adopting practitioner experiences with self-collection as a mechanism to engage people in cervical screening is crucial to informing its continuing roll-out and implementation in other health systems. AIM: This study aimed to describe the experiences of practitioners in Victoria, Australia, who used human papillomavirus (HPV)-based self-collection cervical screening during the first 17 months of its availability. METHODS: Interviews (n = 18) with practitioners from Victoria, who offered self-collection to their patients between December 2017 and April 2019, analysed using template analysis. FINDINGS: Practitioners were overwhelmingly supportive of self-collection cervical screening because it was acceptable to their patients and addressed patients' barriers to screening. Practitioners perceived that knowledge and awareness of self-collection were variable among the primary care workforce, with some viewing self-collection to be inferior to clinician-collected screening. Practitioners championed self-collection at an individual level, with the extent of practice-level implementation depending on resourcing. Concerns regarding supporting the follow-up of self-collected HPV positive patients were noted. Other practical barriers included gaining timely, accurate screening histories from the National Cancer Screening Register to assess eligibility. Practitioners' role surrounded facilitating the choice between screening tests through a patient-centred approach.

Te Ara Waiora-Implementing human papillomavirus (HPV) primary testing to prevent cervical cancer in Aotearoa New Zealand: A protocol for a non-inferiority trial.

BACKGROUND: Cervical cancer is caused by high-risk types of human papillomavirus (HPV). Testing for high-risk HPV is a more sensitive screening method than cervical cytology for detecting cervical changes that may lead to cancer. Consistent with recent evidence of efficacy and acceptability, Aotearoa New Zealand plans to introduce HPV testing as the primary approach to screening, replacing cervical cytology, from mid-2023. Any equitable cervical screening programme must be effective across a diverse population, including women that the current programme fails to reach, particularly Maori and those in rural areas. Currently, we do not know the best model for implementing an equitable HPV self-testing screening programme. METHODS: This implementation trial aims to assess whether a universal offer of HPV self-testing (offered to all people eligible for cervical screening) achieves non-inferior screening coverage (equal) to a universal offer of cervical cytology alone (the present programme). The study population is all people aged from 24.5 to 70 years due for cervical screening in a 12-month period (including those whose screening is overdue or who have never had screening). A range of quantitative and qualitative secondary outcomes will be explored, including barriers and facilitators across screening and diagnostic pathways. This study takes place in Te Tai Tokerau/Northland which covers a diverse range of urban and rural areas and has a large Indigenous Maori population. A total of fourteen practices will be involved. Seven practices will offer HPV self-testing universally to approximately 2800 women and will be compared to seven practices providing routine clinical care (offer of cervical cytology) to an approximately equal number of women. DISCUSSION: This trial will answer important questions about how to implement an equitable, high-quality, effective national programme offering HPV self-testing as the primary screening method for cervical cancer prevention.

Exploring monitoring strategies for population surveillance of HPV vaccine impact using primary HPV screening.

Australia's cervical screening program transitioned from cytology to HPV-testing with genotyping for HPV16/18 in Dec'2017. We investigated whether program data could be used to monitor HPV vaccination program impact (commenced in 2007) on HPV16/18 prevalence and compared estimates with pre-vaccination benchmark prevalence. Pre-vaccination samples (2005-2008) (n = 1933; WHINURS), from 25 to 64-year-old women had been previously analysed with Linear Array (LA). Post-vaccination samples (2013-2014) (n = 2989; Compass pilot), from 25 to 64-year-old women, were analysed by cobas 4800 (cobas), and by LA for historical comparability. Age standardised pre-vaccination HPV16/18 prevalence was 4.85% (95%CI:3.81-5.89) by LA; post-vaccination estimates were 1.67% (95%CI:1.21-2.13%) by LA, 1.49% (95%CI:1.05-1.93%) by cobas, and 1.63% (95%CI:1.17-2.08%) for cobas and LA testing of non-16/18 cobas positives (cobas/LA). Age-standardised pre-vaccination oncogenic HPV prevalence was 15.70% (95%CI:13.79-17.60%) by LA; post-vaccination estimates were 9.06% (95%CI:8.02-10.09%) by LA, 8.47% (95%CI:7.47-9.47%) by cobas and cobas/LA. Standardised rate ratios between post-vs. pre-vaccination rates were significantly different for HPV16/18, non-16/18 HPV and oncogenic HPV: 0.34 (95%CI:0.23-0.50), 0.68 (95%CI:0.55-0.84) and 0.58 (95%CI:0.48-0.69), respectively. Additional strategies (LA for all cobas positives; combined cobas and LA results on all samples) had similar results. If a single method is applied consistently, it will provide important data on relative changes in HPV prevalence following vaccination.

The Implementation of a Primary HPV Self-Testing Cervical Screening Program in Malaysia through Program ROSE-Lessons Learnt and Moving Forward.

Program ROSE (removing obstacles to cervical screening) is a primary HPV-based cervical screening program that incorporates self-sampling and digital technology, ensuring that women are linked to care. It was developed based on the principles of design thinking in the context of Malaysia. The program illustrates the importance of collaborative partnerships and addressing the multi-faceted barriers from policy changes, and infrastructure readiness to the implementation of a radically new cervical screening program in communities. The paradigm shift in cervical cancer requires a monumental and concerted effort in educating both the healthcare providers and the general public. In this short review, we highlight how Pilot Project ROSE incorporated evidence-based tools that rapidly scaled up to Program ROSE. These ideas and solutions can be adapted and adopted by other countries. Notwithstanding the impact of COVID-19, it is incumbent on countries to pave the road towards the elimination of cervical cancer with pre-existing footpaths.

Point-of-care HPV DNA testing of self-collected specimens and same-day thermal ablation for the early detection and treatment of cervical pre-cancer in women in Papua New Guinea: a prospective, single-arm intervention trial (HPV-STAT).

BACKGROUND: WHO recommends human papillomavirus (HPV) testing and same-day treatment for cervical screening in low-income and middle-income countries (LMICs); however, few published data exist on the validity of the strategy. We aimed to evaluate the clinical performance, treatment completion rates, adverse events profile, and acceptability of a fully integrated strategy, comprising point-of-care HPV DNA testing of self-collected specimens and same-day thermal ablation, for screening of cervical cancer in women in Papua New Guinea. METHODS: HPV-STAT was a large-scale, prospective, single-arm intervention trial conducted at two clinical sites in Papua New Guinea. Cervical screening clinics with an on-site consultant gynaecologist were selected in consultation with national and provincial health authorities, church health services, and local stakeholders. Eligible participants were women aged 30-59 years attending cervical screening services at the two clinics, who were willing to comply with study procedures and able to provide written informed consent. Women self-collected vaginal specimens for point-of-care GeneXpert testing (Cepheid, Sunnyvale, CA, USA) for oncogenic HPV types. Women testing positive for HPV underwent pelvic examination followed by same-day thermal ablation or referral for gynaecology review. All HPV-positive women and a 15% random sample of HPV-negative women provided a clinician-collected cervical specimen for liquid-based cytology. The primary outcome was clinical performance (ie, sensitivity, specificity, positive predictive value [PPV], and negative predictive value [NPV]) of the strategy for the detection of high-grade squamous intraepithelial lesion (HSIL) or worse. This trial is registered with ISRCTN, ISRCTN13476702. FINDINGS: Between June 5, 2018, and Jan 6, 2020, we recruited 4285 women, 3638 (84·9%) of whom tested negative for HPV and 647 (15·1%) tested positive for one or more oncogenic HPV type. Sensitivity of the algorithm to detect HSIL or worse was 85·4% (95% CI 81·0-89·6), with specificity 89·6% (88·6-90·6), PPV 35·2% (31·6-39·0), and NPV 98·9% (98·6-99·2). Among HPV-positive women, 602 (93·0%) received same-day thermal ablation and 42 (6·5%) were referred for gynaecology review, 37 (88·1%) of whom attended. Acceptability was high among both HPV-positive and HPV-negative women. Among the 329 HPV-positive women who attended a 3-month follow-up visit, 51 (15·5%) reported mild adverse symptoms that resolved in all cases by the follow-up visit. There were no serious adverse events. INTERPRETATION: We conducted the first real-world evaluation of a fully integrated point-of-care HPV self-collect, test, and treat strategy for same-day cervical screening in a LMIC and found it to be effective, acceptable, and safe when implemented at scale in primary health-care facilities in Papua New Guinea. Our findings support the introduction and scale-up of HPV screening and treatment for the control and elimination of cervical cancer in LMICs, as recommended by WHO.

Exploring beyond the limit: How comparative stochastic performance affects retesting outcomes in six commercial SARS CoV-2 nucleic acid amplification tests.

Objectives: To examine the comparative stochasticity profile of six commercial SARS-CoV-2 nucleic acid amplification tests (NAATs) and how this may affect retesting paradigms. Methods: Commercial quality control (QC) material was serially diluted in viral transport media to create a panel covering 10-10,000 copies/ml. The panel was tested across six commercial NAATs. A subset of high cycle threshold results was retested on a rapid PCR assay to simulate retesting protocols commonly used to discriminate false positives. Results: Performance beyond the LOD differed among assays, with three types of stochasticity profiles observed. The ability of the rapid PCR assay to reproduce a true weak positive specimen was restricted to its own stochastic performance at the corresponding viral concentration. Conclusion: Stochastic performance of various NAATs overlap across low viral concentrations and affect retesting outcomes. Relying on retesting alone to discriminate false positives risk missing true positives even when a more sensitive assay is deployed for confirmatory testing.

Towards the elimination of cervical cancer in low-income and lower-middle-income countries: modelled evaluation of the effectiveness and cost-effectiveness of point-of-care HPV self-collected screening and treatment in Papua New Guinea.

INTRODUCTION: WHO has launched updated cervical screening guidelines, including provisions for primary HPV screen-and-treat. Papua New Guinea (PNG) has a high burden of cervical cancer, but no national cervical screening programme. We recently completed the first field trials of a screen-and-treat algorithm using point-of-care self-collected HPV and same-day treatment (hereafter self-collected HPV S&T) and showed this had superior clinical performance and acceptability to visual inspection of the cervix with acetic acid (VIA). We, therefore, evaluated the effectiveness, cost-effectiveness and resource implications of a national cervical screening programme using self-collected HPV S&T compared with VIA in PNG. METHODS: An extensively validated platform ('Policy1-Cervix') was calibrated to PNG. A total of 38 strategies were selected for investigation, and these incorporated variations in age ranges and screening frequencies and allowed for the identification of the optimal strategy across a wide range of possibilities. A selection of strategies that were identified as being the most effective and cost-effective were then selected for further investigation for longer-term outcomes and budget impact estimation. In the base case, we assumed primary HPV testing has a sensitivity to cervical intraepithelial neoplasia 2 (CIN2+) + of 91.8% and primary VIA of 51.5% based on our earlier field evaluation combined with evidence from the literature. We conservatively assumed HPV sampling and testing would cost US$18. Costs were estimated from a service provider perspective based on data from local field trials and local consultation. RESULTS: Self-collected HPV S&T was more effective and more cost-effective than VIA. Either twice or thrice lifetime self-collected HPV S&T would be cost-effective at 0.5× gross domestic product (GDP) per capita (incremental cost-effectiveness ratio: US$460-US$656/life-years saved; 1GDPper-capita: US$2829 or PGK9446 (year 2019)) and could prevent 33 000-42 000 cases and 23 000-29 000 deaths in PNG over the next 50 years, if scale-up reached 70% coverage from 2023. CONCLUSION: Self-collected HPV S&T was effective and cost-effective in the high-burden, low-resource setting of PNG, and, if scaled-up rapidly, could prevent over 20 000 deaths over the next 50 years. VIA screening was not effective or cost-effective. These findings support, at a country level, WHO updated cervical screening guidelines and indicate that similar approaches could be appropriate for other low-resource settings.

National experience in the first two years of primary human papillomavirus (HPV) cervical screening in an HPV vaccinated population in Australia: observational study.

OBJECTIVE: To review the first two years of the primary human papillomavirus (HPV) cervical screening programme in an HPV vaccinated population. DESIGN: Observational study. SETTING: Australia. PARTICIPANTS: 3 745 318 women with a primary HPV test between 1 December 2017 and 31 December 2019; most women aged <40 years had previously been offered vaccination against HPV16 and HPV18. INTERVENTIONS: Primary HPV screening with referral if HPV16 or HPV18 (HPV16/18) positive and triage with liquid based cytology testing (threshold atypical squamous cells-cannot exclude high grade squamous intraepithelial lesion) for women who were positive for high risk HPV types other than 16/18. A 12 month follow-up HPV test was recommended in triaged women with a negative or low grade cytology result, with referral if they tested positive for any high risk HPV type at follow-up. MAIN OUTCOME MEASURES: Proportion of women who had attended for their first HPV screening test, tested positive, and were referred for colposcopy; and short term risk of detecting cervical intraepithelial neoplasia (CIN) grade 2 or worse, CIN grade 3 or worse, or cancer. RESULTS: 54.6% (n=3 507 281) of an estimated 6 428 677 eligible women aged 25-69 had undergone their first HPV test by the end of 2019. Among those attending for routine screening, positivity for HPV16/18 and for HPV types not 16/18 was, respectively, 2.0% and 6.6% in women aged 25-69 (n=3 045 844) and 2.2% and 13.3% in highly vaccinated cohorts of women aged 25-34 (n=768 362). Colposcopy referral (ages 25-69 years) was 3.5%, increasing to an estimated 6.2% after accounting for women who had not yet had a 12 month repeat test. Cervical cancer was detected in 0.98% (456/46 330) of women positive for HPV16/18 at baseline, including 0.32% (89/28 003) of women with HPV16/18 and negative cytology. Women with HPV types not 16/18 and negative or low grade cytology at both baseline and 12 months were at low risk of serious disease (3.4% CIN grade 3 or worse; 0.02% cancer; n=20 019) but estimated to account for 62.0% of referrals for this screening algorithm. CONCLUSIONS: Colposcopy referral thresholds need to consider underlying cancer risk; on this basis, women with HPV16/18 in the first round of HPV screening were found to be at higher risk regardless of cytology result, even in a previously well screened population. Women with HPV types not 16/18 and negative or low grade cytology showed a low risk of serious abnormalities but constitute most referrals and could be managed safely with two rounds of repeat HPV testing rather than one. HPV16/18 driven referrals were low in HPV vaccinated cohorts.

HPV self-sampling and follow-up over two rounds of cervical screening in Australia - the iPap trial.

OBJECTIVES: Previously, based on 6 months of follow-up, we showed that HPV self-sampling improved participation in cervical screening compared to a reminder letter for Pap testing for never- and under-screened women. Here, we report follow-up and related screening outcomes for women who participated in the initial self-sampling over two screening rounds. SETTING: The randomised controlled trial was conducted in Australia. METHODS: Never- and under-screened women were randomly allocated to the HPV self-sampling or the reminder for Pap test arm and followed at 6 and 36 months since the kits were first mailed. RESULTS: The first round of HPV self-sampling kits were mailed from May-July 2014 to 12 572 women. After 36 months, 19% of never-screened and 9% of under-screened women returned a kit for HPV testing; 2.7% were HPV 16/18 and 5.8% non-16/18 HPV positive. Compliance with first round follow-up was 84% (95% CI: 77.1-89.5%). Non-compliant and cytology triage negative women were mailed another kit at 12 months. Compliance at 12-month follow-up was 59.3% (49.4 to 68.6%). Of 37 women with a 12-month repeat HPV, 70% were positive. Of women who tested negative for HPV in the first round (n = 1573), 25% attended regular screening in the next round and none had CIN2 + detected. The overall prevalence of CIN2 + was 8.5 per 1000 screened (4.8 to 13.9 per 1000). CONCLUSION: While self-sampling can successfully engage women, compliance with repeat testing may require monitoring. The clinician-supported self-collection pathway now in use in Australia will likely improve women's engagement with follow-up.

The experience of under-screened and never-screened participants using clinician-supported self-collection cervical screening within the Australian National Cervical Screening Program.

BACKGROUND: Australia has had significant successes in the prevention of cervical cancer. However, there is considerable scope for improving screening participation. In December 2017, Australia shifted from cytology to a human papillomavirus-based screening program as part of the renewed National Cervical Screening Program. This provided the opportunity to introduce a clinician-supported self-collection cervical screening pathway, which allows screening participants aged 30 years or more and who are under-screened or never-screened to screen via a self-collected human papillomavirus test. OBJECTIVE: This study aimed to explore screening participant experiences of a clinician-supported self-collection cervical screening pathway. METHODS: Interviews (n = 45) were conducted with participants who had used the clinician-supported self-collection cervical screening pathway in the Australian National Cervical Screening Program between December 2017 and April 2019. Interviews were analyzed using template analysis. RESULTS: Under-screened and never-screened participants reported a variety of interrelated barriers to cervical screening due to the nature of the test. For these participants, self-collection was a preferable way to perform screening as it overcame various barriers, was easy to use and promoted a sense of empowerment. Participants reported that the role of their practitioner was influential in their decision to undertake cervical screening, and that the support and information provided was a key factor in their experiences of the self-collection pathway. CONCLUSION: Findings support the use of a clinician-supported model of care, as an alternative screening modality in Australia's National Cervical Screening Program. As more countries consider the move from a cytology to human papillomavirus-based cervical screening program, this model may assist in greater engagement of under-screened participants.

Management of Chlamydia Cases in Australia (MoCCA): protocol for a non-randomised implementation and feasibility trial.

INTRODUCTION: The sexually transmitted infection chlamydia can cause significant complications, particularly among people with female reproductive organs. Optimal management includes timely and appropriate treatment, notifying and treating sexual partners, timely retesting for reinfection and detecting complications including pelvic inflammatory disease (PID). In Australia, mainstream primary care (general practice) is where most chlamydia infections are diagnosed, making it a key setting for optimising chlamydia management. High reinfection and low retesting rates suggest partner notification and retesting are not uniformly provided. The Management of Chlamydia Cases in Australia (MoCCA) study seeks to address gaps in chlamydia management in Australian general practice through implementing interventions shown to improve chlamydia management in specialist services. MoCCA will focus on improving retesting, partner management (including patient-delivered partner therapy) and PID diagnosis. METHODS AND ANALYSIS: MoCCA is a non-randomised implementation and feasibility trial aiming to determine how best to implement interventions to support general practice in delivering best practice chlamydia management. Our method is guided by the Consolidated Framework for Implementation Research and the Normalisation Process Theory. MoCCA interventions include a website, flow charts, fact sheets, mailed specimen kits and autofills to streamline chlamydia consultation documentation. We aim to recruit 20 general practices across three Australian states (Victoria, New South Wales, Queensland) through which we will implement the interventions over 12-18 months. Mixed methods involving qualitative and quantitative data collection and analyses (observation, interviews, surveys) from staff and patients will be undertaken to explore our intervention implementation, acceptability and uptake. Deidentified general practice and laboratory data will be used to measure pre-post chlamydia testing, retesting, reinfection and PID rates, and to estimate MoCCA intervention costs. Our findings will guide scale-up plans for Australian general practice. ETHICS AND DISSEMINATION: Ethics approval was obtained from The University of Melbourne Human Research Ethics Committee (Ethics ID: 22665). Findings will be disseminated via conference presentations, peer-reviewed publications and study reports.

The road to cervical cancer elimination in Malaysia: Evaluation of the impact and cost-effectiveness of human papillomavirus screening with self-collection and digital registry support.

The WHO has launched a global strategy to eliminate cervical cancer through the scale-up of human papillomavirus (HPV) vaccination, cervical screening, and cervical cancer treatment. Malaysia has achieved high-coverage HPV vaccination since 2010, but coverage of the existing cytology-based program remains low. Pilot studies found HPV self-sampling was acceptable and effective, with high follow-up rates when a digital registry was used, and recently the Malaysian Government announced plans for a national HPV-based screening program. We therefore evaluated the impact of primary HPV screening with self-collection in Malaysia in the context of Malaysia's existing vaccination program. We used the "Policy1-Cervix" modeling platform to assess health outcomes, cost-effectiveness, resource use and cervical cancer elimination timing (the year when cervical cancer rates reach four cases per 100 000 women) of implementing primary HPV testing with self-collection, assuming 70% routine-screening coverage could be achieved. Based on available data, we assumed that compliance with follow-up was 90% when a digital registry was used, but that compliance with follow-up would be 50-75% without the use of a digital registry. We found that the current vaccination program would prevent 27 000 to 32 200 cervical cancer cases and 11 700 to 14 000 deaths by 2070. HPV testing with a digital registry was cost-effective (CER = $US 6953-7549 < $US 11 373[<1×GDP per capita]) and could prevent an additional 15 900 to 17 800 cases and 9700 to 10 600 deaths by 2070, expediting national elimination by 11 to 20 years, to 2055 to 2059. If HPV screening were implemented without a digital registry, there would be 1800 to 4900 fewer deaths averted by 2070 and the program would be less cost-effective. These results underline the importance of HPV testing as a key elimination pillar in Malaysia.

Self-collection cervical screening in the renewed National Cervical Screening Program: a qualitative study.

OBJECTIVES: To evaluate the implementation and acceptability of the self-collection cervical screening pathway since commencement of the renewed National Cervical Screening Program (rNCSP), from the perspectives of screening participants and primary care practitioners. DESIGN, SETTING, PARTICIPANTS: Qualitative study; individual semi-structured interviews with 45 screening participants and 18 primary care practitioners in Victoria who had engaged with the self-collection pathway during the first 17 months of the rNCSP (1 December 2017 - 30 April 2019). RESULTS: The self-collection pathway was highly acceptable as an alternative cervical screening pathway for most participating screening participants and practitioners. Some screening participants indicated that they would not have been screened had the pathway not been available. Acceptability was lower among those who had tested positive for HPV types not 16/18, a result that requires additional testing of a clinician-collected cervical sample. Use of the self-collection pathway is driven more by practitioners than their patients. Interpretations of the self-collection guidelines varied between practices. Barriers to expanding promotion of the pathway by practitioners included difficulties with identifying eligible participants. CONCLUSIONS: Increasing the accessibility of the self-collection pathway to under- and never screened women could reduce inequities in cervical cancer outcomes for those not participating in the main screening pathway. Practitioners should be provided resources to integrate self-collection into routine practice and to efficiently implement the entire self-collection pathway, in order to maximise its use and to optimise the experience for screening participants.
