Barriers Associated with Adherence to Cervical Cancer Screening Among Women Living with HIV in Nkhatabay District, Malawi: A Mixed-Methods Study

Background

Cervical cancer (CC) incidence among Women Living with HIV (WLHIV) is high compared to the general population of women. As such, the Malawi National CC guideline recommends yearly screening among WLHIV. However, only 15.9% of WLHIV were screened nationally using Visual Inspection with Acetic Acid (VIA) by 2015 and there is no data regarding adherence and barriers to yearly screening. This study assessed adherence levels and associated barriers to yearly Cervical Cancer screening (CCS) among WLHIV.

Methods

A cross-sectional concurrent mixed-method study was conducted at Nkhatabay District Hospital (NBDH) and Chintheche Rural Hospital (CRH) in Malawi. A sample of 205 WLHIV participated in quantitative strand and in-depth interviews were conducted with 10 health care workers and 10 WLHIV. Quantitative data were analysed using STATA version 16. Pearson's chi-square test and Multivariate logistic regression analysis were performed. P value was set at 0.05. Qualitative data were analysed deductively following six steps of thematic analysis.

Results

Only 5.4% (n=11) of the participants had been screened as required. Women aged ≥45 had 4 times the odds of being screened for CC compared to ≤30 (OR 4.18, 95% CI 0.65-26.8). WLHIV on ART > 10 years had more than 5 times the odds of being screened (OR 5.9, 95% CI 1.08-33.19) compared with those on ART <3 years. Use of male service providers (p =< 0.001), fear of the VIA procedure (p = <0.001) and lack of interest (p = <0.015) were significant barriers to adherence. Qualitative findings revealed a lack of knowledge regarding CCS protocol and the use of male providers.

Conclusion

WLHIV face many challenges in accessing CCS and adherence to yearly CCS is very low. There is urgent need for targeted community awareness, scaling up of HPV tests and incorporation of CCS into routine integrated outreach services.

Drivers of cervical cancer prevention and management in sub-Saharan Africa: a qualitative synthesis of mixed studies

BACKGROUND

Cervical cancer is a public health concern in the sub-Saharan Africa region. Cervical cancer screening is one of the strategies for detecting early precancerous lesions. However, many women have poor access to and utilization of screening services in the region. This review aimed to synthesize evidence on the challenges and opportunities of screening, early detection and  management of cervical cancer in sub-Saharan Africa.

METHODS

We conducted a structured narrative review of studies published in English. We included studies published from 1 January 2013 to mid-2022. Studies were selected following Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guidelines. Key search terms (detractors and enablers, cervical cancer screening, sub-Saharan Africa) were employed to identify studies from three electronic databases (HINARI, Science Direct, and PubMed). We also conducted searches on Google Scholar to identify relevant grey literatures. A thematic analysis was conducted and themes were identified, then explained using a socio-ecological framework (intrapersonal, interpersonal, organizational, community, policy levels).

RESULTS

We identified 60 studies in the final review. Cervical cancer screening and early detection and management programmes are influenced by drivers at multiple levels. Individual-level drivers included a lack of knowledge about cervical cancer and screening literacy, and a low risk in perception, attitude, susceptibility and perceived fear of test results, as well as sociodemographic characteristics of women. Interpersonal drivers were community embarrassment, women's relationships with health workers, support and encouragement, the presence of peers or relatives to model preventive behaviour, and the mothers' networks with others. At the organizational level, influencing factors were related to providers (cervical cancer screening practice, training, providers' profession type, skill of counselling and sex, expert recommendation and work commitments). At the community level, drivers of cervical cancer screening included stigma, social-cultural norms, social networks and beliefs. System- and policy-level drivers were lack of nearby facilities and geographic remoteness, resource allocation and logistics management, cost of screening, promotion policy, ownership and management, lack of decentralized cancer policy and lack of friendly infrastructure.

CONCLUSIONS

There were several drivers in the implementation of cervical cancer screening programmes at multiple levels. Prevention and management of cervical cancer programmes requires multilevel strategies to be implemented  across the individual level (users), community and organizational levels (providers and community users), and system and policy levels. The design and implementation of policies and programmes need to address the multilevel challenges.

HPV DNA Testing and Mobile Colposcopy for Cervical Precancer Screening in HIV Positive Women: A Comparison Between Two Settings in Ghana and Recommendation for Screening

INTRODUCTION

Women living with HIV (WLHIV) have higher prevalence and persistence rates of high-risk human papillomavirus (hr-HPV) infection with a six-fold increased risk of cervical cancer. Thus, more frequent screening is recommended for WLHIV.

OBJECTIVES

This retrospective descriptive cross-sectional study was conducted to investigate and compare the prevalence of hr-HPV infection and abnormal findings on mobile colposcopy in two cohorts of WLHIV following cervical screening in rural and urban settings in Ghana.

METHODS

Through the mPharma 10 000 Women Initiative, WLHIV were screened via concurrent hr-HPV DNA testing (MA-6000; Sansure Biotech Inc., Hunan, China) and visual inspection (Enhanced Visual Assessment [EVA] mobile colposcope; MobileODT, Tel Aviv, Israel) by trained nurses. The women were screened while undergoing routine outpatient reviews at HIV clinics held at the Catholic Hospital, Battor (rural setting) and Tema General Hospital (urban setting), both in Ghana.

RESULTS

Two-hundred and fifty-eight WLHIV were included in the analysis (rural, n = 132; urban, n = 126). The two groups were comparable in terms of age, time since HIV diagnosis, and duration of treatment for HIV. The hr-HPV prevalence rates were 53.7% (95% CI, 45.3-62.3) and 48.4% (95% CI, 39.7-57.1) among WLHIV screened in the rural vs urban settings (p-value = .388). Abnormal colposcopy findings were found in 8.5% (95% CI, 5.1-11.9) of the WLHIV, with no significant difference in detection rates between the two settings (p-value = .221). Three (13.6%) of 22 women who showed abnormal colposcopic findings underwent loop electrosurgical excision procedure (LEEP), leaving 19/22 women from both rural and urban areas with pending treatment/follow-up results, which demonstrates the difficulty faced in reaching early diagnosis and treatment, regardless of their area of residence. Histopathology following LEEP revealed CIN III in 2 WLHIV (urban setting, both hr-HPV negative) and CIN I in 1 woman in the rural setting (hr-HPV positive).

CONCLUSIONS

There is a high prevalence of hr-HPV among WLHIV in both rural and urban settings in this study in Ghana. Concurrent HPV DNA testing with a visual inspection method (colposcopy/VIA) reduces loss to follow-up compared to performing HPV DNA testing as a standalone test and recalling hr-HPV positive women for follow up with a visual inspection method. Concurrent HPV DNA testing and a visual inspection method may also pick up precancerous cervical lesions that are hr-HPV negative and may be missed if HPV DNA testing is performed alone.

High-risk human papillomavirus genotype distribution among women living with HIV; implication for cervical cancer prevention in a resource limited setting

BACKGROUND

For women living with HIV (WLHIV), the burden of persistent HPV infection, cervical pre-cancerous lesions and cancer have been demonstrated to be higher than among HIV-negative women. As Ghana and other lower-middle-income countries (LMIC) work toward developing national cervical cancer programmes, it is essential that local scientific evidence be provided to guide policy decisions, especially for such special populations. The objective of this study was to determine the distribution of high-risk HPV genotype and related factors among WLHIV and its implication for the prevention of cervical cancer prevention efforts.

METHODS

A cross-sectional study was conducted at the Cape Coast Teaching Hospital in Ghana. WLHIV, aged 25-65 years, who met the eligibility criteria were recruited through a simple random sampling method. An interviewer-administered questionnaire was used to gather socio-demographic, behavioural, clinical and other pertinent information. The AmpFire HPV detection system (Atila BioSystem, Mointain View, CA was used to detect 15 high-risk HPV genotypes from self-collected cervico-vaginal samples. The data collected were exported to STATA 16.0 for statistical analysis.

RESULTS

In all, 330 study participants, with mean age of 47.2 years (SD ± 10.7), were involved. Most (69.1%, n = 188/272) had HIV viral loads < 1000 copies/ml and 41.2% (n = 136) had ever heard of cervical screening. The overall hr-HPV prevalence was 42.7% (n = 141, 95% CI 37.4-48.1) and the five commonest hr-HPV types among screen positives were HPV59 (50.4%), HPV18 (30.5%), HPV35 (26.2%), HPV58 (17%) and HPV45 (14.9%). Most infected women (60.3%, n = 85) had multiple hr-HPV infections, with about 57.4% (n = 81) having 2-5 h-HPV types, while 2.8% (n = 4) had more than five hr-HPV types. A total of 37.6% (n = 53) had HPV16 and/or18, while 66.0% (n = 93) had the hr-HPV genotypes covered by the nonavalent vaccine. Women with HIV viral load ≥ 1000copies/ml (AOR = 5.58, 95% CI 2.89-10.78, p < 0.001) had a higher likelihood of being co-infected.

CONCLUSION

This study found out that the prevalence of hr-HPV still remains high in women with HIV, with a notable occurrence of multiple infections and infection with genotypes 16 and/or18. Additionally, an association was established between hr-HPV and infection HIV viral load.. Therefore, comprehensive HIV care for these women should include awareness of cervical cancer, consideration of vaccination and implementation of screening and follow-up protocols. National programmes in LMIC, such as Ghana, should consider using HPV-based screen-triage-treat approach with partial genotyping.

Barriers to cervical cancer and breast cancer screening uptake in low- and middle-income countries: a systematic review

There is an alarmingly high growth in breast and cervical cancers in low- and middle-income countries. Due to late presentation to doctors, there is a lower cure rate. The screening programmes in low- and middle-income countries are not comprehensive. In this paper, we systematically analyse the barriers to screening through an accessibility framework. We performed a systematic literature search in PubMed, Mendeley and Google Scholar to retrieve all English language studies (quantitative, qualitative and mixed-methods) that contained information on breast and cervical cancer screening in low- and middle-income countries. We only considered publications published between 1 January 2016 and 31 May 2021. The review was guided by Preferred Reporting Items for Systematic Reviews and Meta-Analyses literature search extension (PRISMA-S), an extension to the PRISMA Statement for Reporting Literature Searches in Systematic Reviews. The search yielded a total of 67 articles from low- and middle-income countries in this review. We used a framework on accessibility known as the 5A framework, which distinguishes five aspects of access: approachability, acceptability, availability, affordability and appropriateness, to classify the screening barriers. We added two more aspects: awareness and angst, as they could explain other important barriers to screening. They confirmed how the lack of awareness, cost of the screening service and distance to the screening centre act as major impediments to screening. They also revealed how embarrassment and fear of screening and cultural factors such as lack of spousal or family support could be obstacles to screening. We conclude that more needs to be done by policymakers and governments to improve the confidence of the people in the health systems. Women should be made aware of the causes and risk factors of cancer through evidence-based strategies so that there is an increased adherence to screening.

Barriers to Cervical Cancer Screening Among Women Living With HIV in Low- and Middle-Income Countries: A Systematic Review

Women living with HIV in low-and-middle-income countries (LMICs) are at high risk of developing cervical cancer due to their immunocompromised status. Screening is an imperative prevention measure for early detection and for ultimately reducing high rates of cervical cancer; however, cervical cancer screening uptake among this group remains low. This systematic review aimed to identify barriers to cervical cancer screening among women living with HIV in LMIC. A comprehensive literature search was undertaken, and an analysis of included studies was completed to abstract major themes related to cervical cancer screening barriers for women living with HIV in LMIC. Lack of cervical cancer and cervical cancer screening knowledge among patients was found to be the most prevalent barrier to cervical cancer screening. Our findings highlight a dire need for interventions to increase knowledge and awareness of cervical cancer screening among women living with HIV in LMIC, along with addressing barriers within health care systems.
