ABSTRACT

BACKGROUND: Mobile health (mHealth) has become an increasingly popular strategy to improve healthcare delivery and health outcomes. Communicating results and health education via text may facilitate program planning and promote better engagement in care for women undergoing human papillomavirus (HPV) screening. We sought to develop and evaluate an mHealth strategy with enhanced text messaging to improve follow-up throughout the cervical cancer screening cascade. METHODS: Women aged 25-65 participated in HPV testing in six community health campaigns (CHCs) in western Kenya as part of a single arm of a cluster-randomized trial. Women received their HPV results via text message, phone call, or home visit. Those who opted for text in the first four communities received "standard" texts. After completing the fourth CHC, we conducted two semi-structured focus group discussions with women to develop an "enhanced" text strategy, including modifying the content, number, and timing of texts, for the subsequent two communities. We compared the overall receipt of results and follow-up for treatment evaluation among women in standard and enhanced text groups. RESULTS: Among 2368 women who were screened in the first four communities, 566 (23.9%) received results via text, 1170 (49.4%) via phone call, and 632 (26.7%) via home visit. In the communities where enhanced text notification was offered, 264 of the 935 screened women (28.2%) opted for text, 474 (51.2%) opted for phone call, and 192 (20.5%) for home visit. Among 555 women (16.8%) who tested HPV-positive, 257 (46.3%) accessed treatment, with no difference in treatment uptake between the standard text group (48/90, 53.3%) and the enhanced text group (22/41, 53.7%). More women in the enhanced text group had prior cervical cancer screening (25.8% vs. 18.4%; p < 0.05) and reported living with HIV (32.6% vs. 20.2%; p < 0.001) than those in the standard text group. CONCLUSIONS: Modifying the content and number of texts as an enhanced text messaging strategy was not sufficient to increase follow-up in an HPV-based cervical cancer screening program in western Kenya. A one-size approach to mHealth delivery does not meet the needs of all women in this region. More comprehensive programs are needed to improve linkage to care to further reduce structural and logistical barriers to cervical cancer treatment.

ABSTRACT

High rates of maternal and neonatal morbidity and mortality in Kenya may be influenced by provider training and knowledge in emergency obstetric and neonatal care in addition to availability of supplies necessary for this care. While post-abortion care is a key aspect of life-saving maternal health care, no validated questionnaires have been published on provider clinical knowledge in this arena. Our aim was to determine provider knowledge of maternal-child health (MCH) emergencies (post-abortion care, pre-eclampsia, postpartum hemorrhage, neonatal resuscitation) and determine factors associated with clinical knowledge. Our secondary aim was to pilot a case-based questionnaire on post-abortion care. We conducted a cross-sectional survey of providers at health facilities in western Kenya providing maternity services. Providers estimated facility capacity through perceived availability of both general and specialized supplies. Providers reported training on the MCH topics and completed case-based questions to assess clinical knowledge. Knowledge was compared between topics using a linear mixed model. Multivariable models identified variables associated with scores by topic. 132 providers at 37 facilities were interviewed. All facilities had access to general supplies at least sometime while specialized supplies were available less frequently. While only 56.8% of providers reported training on post-abortion care, more than 80% reported training on pre-eclampsia, postpartum hemorrhage, and neonatal resuscitation. Providers' clinical knowledge across all topics was low (mean score of 63.3%), with significant differences in scores by topic area. Despite less formal training in the subject area, providers answered 71.6% (SD 16.7%) questions correctly on post-abortion care. Gaps in supply availability, training, and clinical knowledge on MCH emergencies exist. Increasing training on MCH topics may decrease pregnancy and postpartum complications. Further, validated tools to assess knowledge in post-abortion care should be created, particularly in sub-Saharan Africa where legal restrictions on abortion services exist and many abortions are performed in unsafe settings.

ABSTRACT

BACKGROUND: Cervical cancer screening through self-collected high-risk human papillomavirus (HPV) testing has increased screening uptake, particularly in low-resource settings. Improvement ultimately depends, however, on women with positive results accessing follow-up treatment. Identifying the barriers to timely treatment is needed to tailor service delivery for maximum impact. MATERIALS AND METHODS: This qualitative study was conducted within a self-collected HPV screening trial in Migori County, Kenya. HPV-positive women were referred for no-cost cryotherapy treatment at the county hospital. Women not attending within 60 days of receiving HPV-positive results were randomly selected for in-depth interviews (IDIs). IDIs were coded and analyzed to develop an analytical framework and identify treatment barriers. RESULTS: Eighty-one women were interviewed. IDIs showed a poor understanding of HPV and cervical cancer, impacting comprehension of screening results and treatment instructions. All 81 had not undergone treatment but reported intending to in the future. Eight reported seeking treatment unsuccessfully or not qualifying, primarily due to pregnancy. Transportation costs and long distances to the hospital were the most reported barriers to treatment. Other obstacles included work, household obligations, and fear of treatment. Impacts of social influences were mixed; some women reported their husbands prevented seeking treatment, others reported their husbands provided financial or emotional support. Few women experienced peer support. CONCLUSIONS: Women faced many barriers to treatment following HPV screening in rural Kenya. Transportation barriers highlight a need for local treatment capacity or screen-and-treat approaches. Ensuring women understand their results and how to seek treatment is essential to improving cervical cancer screening in low-resource settings.

ABSTRACT

INTRODUCTION: Despite the increased risk of cervical cancer among HIV-positive women, many HIV-care programs do not offer integrated cervical cancer screening. Incorporating self-collected Human Papillomavirus (HPV) testing into HIV programs is a potential strategy to identify women at higher risk for cervical cancer while leveraging the staffing, infrastructure and referral systems for existing services. Community-based HIV and HPV testing has been effective and efficient when offered in single-disease settings. METHODS: This cross-sectional study was conducted within a community outreach and multi-disease screening campaigns organized by the Family AIDS Care and Education Services in Kisumu County, Kenya. In addition to HIV testing, the campaigns provided screening for TB, malaria, hypertension, diabetes, and referrals for voluntary medical male circumcision. After these services, women aged 25-65 were offered self-collected HPV testing. Rates and predictors of cervical cancer screening uptake and of HPV positivity were analyzed using tabular analysis and Fisher's Exact Test. Logistic regression was performed to explore multivariate associations with screening uptake. RESULTS: Among the 2016 women of screening age who attended the outreach campaigns, 749 women (35.6%) were screened, and 134 women (18.7%) were HPV-positive. In bivariate analysis, women who had no children (p < 0.01), who were not pregnant (p < 0.01), who were using contraceptives (p < 0.01), who had sex without using condoms (p < 0.05), and who were encouraged by a family member other than their spouse (p < 0.01), were more likely to undergo screening. On multivariable analysis, characteristics associated with higher screening uptake included: women aged 45-54 (OR 1.62, 95% CI 1.05-2.52) compared to women aged 25-34; no children (OR 1.65, 95% CI 1.06-2.56); and family support other than their spouse (OR 1.53, 95% CI 1.09-2.16). Women who were pregnant were 0.44 times (95% CI 0.25-0.76) less likely to get screened. Bivariate analyses with participant characteristics and HPV positivity found that women who screened HPV-positive were more likely to be HIV-positive (p < 0.001) and single (p < 0.001). CONCLUSIONS: The low screening uptake may be attributed to implementation challenges including long waiting times for service at the campaign and delays in procuring HPV test kits. However, given the potential benefits of integrating HPV testing into HIV outreach campaigns, these challenges should be examined to develop more effective multi-disease outreach interventions.

ABSTRACT

BACKGROUND: Cervical cancer is a leading cause of cancer deaths among women of reproductive age in Peru. Screening and early identification of pre-cancerous lesions are a cornerstone of the cervical cancer prevention strategy. Yet, there is limited literature on barriers to screening among Peruvian women. In this cross-sectional study, we aimed to examine Peruvian women's knowledge, attitudes, and practices regarding cervical cancer screening and identify possible reasons for the gap between knowledge and screening. METHODS: The study was conducted in metropolitan Lima from June-August 2019. We purposefully recruited 12 women who had previously been screened, and 12 who had never been screened for cervical cancer. The women completed a 40-question knowledge and attitude survey and an in-depth interview about barriers to screening. Descriptive analysis was used to calculate a knowledge and attitude score and qualitative analysis was guided by the Health Belief Model constructs. RESULTS: Previously screened participants had greater knowledge of cervical cancer symptoms, risk factors, and prevention (mean score = 28.08, S.D. = 4.18) compared to participants who had never been screened (mean score = 21.25, S.D. = 6.35). Both groups described lack of priority and embarrassment as barriers to cervical cancer screening. For participants who had never been screened before, major barriers included the fear of a cancer diagnosis and lack of information about screening services. Pregnancy, unusual gynecological symptoms and encouragement from friends and family were cues to action for participants seeking screening. Most participants in both groups recognized the benefits of getting screened for cervical cancer. Being previously screened increased participants' self-efficacy for engaging in screening behaviors again. Misconceptions regarding screening procedures and cervical cancer were also noted as barriers for participants accessing screening services. CONCLUSIONS: Improving knowledge and awareness about cervical cancer and screening programs may improve screening behaviors among women. Targeting women who have never been screened before and addressing their fears and concerns around embarrassment may be other areas for intervention. Misconceptions that deter women from screening services are an important issue that should be addressed in order to increase the number of women who get timely screenings.

ABSTRACT

BACKGROUND: Nearly 90% of deaths due to cervical cancer occur in low- and middle-income countries (LMICs). In recent years, many digital health strategies have been implemented in LMICs to ameliorate patient-, provider-, and health system-level challenges in cervical cancer control. However, there are limited efforts to systematically review the effectiveness and current landscape of digital health strategies for cervical cancer control in LMICs. OBJECTIVE: We aim to conduct a systematic review of digital health strategies for cervical cancer control in LMICs to assess their effectiveness, describe the range of strategies used, and summarize challenges in their implementation. METHODS: A systematic search was conducted to identify publications describing digital health strategies for cervical cancer control in LMICs from 5 academic databases and Google Scholar. The review excluded digital strategies associated with improving vaccination coverage against human papillomavirus. Titles and abstracts were screened, and full texts were reviewed for eligibility. A structured data extraction template was used to summarize the information from the included studies. The risk of bias and data reporting guidelines for mobile health were assessed for each study. A meta-analysis of effectiveness was planned along with a narrative review of digital health strategies, implementation challenges, and opportunities for future research. RESULTS: In the 27 included studies, interventions for cervical cancer control focused on secondary prevention (ie, screening and treatment of precancerous lesions) and digital health strategies to facilitate patient education, digital cervicography, health worker training, and data quality. Most of the included studies were conducted in sub-Saharan Africa, with fewer studies in other LMIC settings in Asia or South America. A low risk of bias was found in 2 studies, and a moderate risk of bias was found in 4 studies, while the remaining 21 studies had a high risk of bias. A meta-analysis of effectiveness was not conducted because of insufficient studies with robust study designs and matched outcomes or interventions. CONCLUSIONS: Current evidence on the effectiveness of digital health strategies for cervical cancer control is limited and, in most cases, is associated with a high risk of bias. Further studies are recommended to expand the investigation of digital health strategies for cervical cancer using robust study designs, explore other LMIC settings with a high burden of cervical cancer (eg, South America), and test a greater diversity of digital strategies.

ABSTRACT

BACKGROUND: Primary human papillomavirus (HPV) screening (PHS) utilizes oncogenic human papillomavirus (oncHPV) testing as the initial cervical cancer screening method and typically, if positive, additional reflex-triage (eg, HPV16/18-genotyping, Pap testing). While US guidelines support PHS usage in the general population, PHS has been little studied in women living with HIV (WLWH). METHODS: We enrolled n = 865 WLWH (323 from the Women's Interagency HIV Study [WIHS] and 542 from WIHS-affiliated colposcopy clinics). All participants underwent Pap and oncHPV testing, including HPV16/18-genotyping. WIHS WLWH who tested oncHPV[+] or had cytologic atypical squamous cells of undetermined significance or worse (ASC-US+) underwent colposcopy, as did a random 21% of WLWH who were oncHPV[-]/Pap[-] (controls). Most participants additionally underwent p16/Ki-67 immunocytochemistry. RESULTS: Mean age was 46 years, median CD4 was 592 cells/µL, 95% used antiretroviral therapy. Seventy WLWH had histologically-determined cervical intraepithelial neoplasia grade 2 or greater (CIN-2+), of which 33 were defined as precancer (ie, [i] CIN-3+ or [ii] CIN-2 if concurrent with cytologic high grade squamous intraepithelial lesions [HSILs]). PHS had 87% sensitivity (Se) for precancer, 9% positive predictive value (PPV), and a 35% colposcopy referral rate (Colpo). "PHS with reflex HPV16/18-genotyping and Pap testing" had 84% Se, 16% PPV, 30% Colpo. PHS with only HPV16/18-genotyping had 24% Colpo. "Concurrent oncHPV and Pap Testing" (Co-Testing) had 91% Se, 12% PPV, 40% Colpo. p16/Ki-67 immunochemistry had the highest PPV, 20%, but 13% specimen inadequacy. CONCLUSIONS: PHS with reflex HPV16/18-genotyping had fewer unnecessary colposcopies and (if confirmed) could be a potential alternative to Co-Testing in WLWH.

ABSTRACT

OBJECTIVES: This study aimed to report the proportion of women with a new diagnosis of cervical cancer recommended for curative hysterectomy as well as associated factors. We also report recommended treatments by stage and patterns of treatment initiation. DESIGN: This was an observational cohort study. Inperson surveys were followed by a phone call. SETTING: Participants were recruited at the two public tertiary care referral hospitals in Kampala, Uganda. PARTICIPANTS: Adult women with a new diagnosis of cervical cancer were eligible: 332 were invited to participate, 268 met the criteria and enrolled, and 255 completed both surveys. PRIMARY AND SECONDARY OUTCOMES MEASURES: The primary outcome of interest was surgical candidacy; a secondary outcome was treatment initiation. Descriptive and multivariate statistical analyses examined the associations between predictors and outcomes. Sensitivity analyses were performed to examine outcomes in subgroups, including stage and availability of radiation. RESULTS: Among 268 participants, 76% were diagnosed at an advanced stage (IIB-IVB). In total, 12% were recommended for hysterectomy. In adjusted analysis, living within 15 km of Kampala (OR 3.10, 95% CI 1.20 to 8.03) and prior screening (OR 2.89, 95% CI 1.22 to 6.83) were significantly associated with surgical candidacy. Radiotherapy availability was not significantly associated with treatment recommendations for early-stage disease (IA-IIA), but was associated with recommended treatment modality (chemoradiation vs primary chemotherapy) for locally advanced stage (IIB-IIIB). Most (67%) had started treatment. No demographic or health factor, treatment recommendation, or radiation availability was associated with treatment initiation. Among those recommended for hysterectomy, 55% underwent surgery. Among those who had initiated treatment, 82% started the modality that was recommended. CONCLUSION: Women presented to public referral centres in Kampala with mostly advanced-stage cervical cancer and few were recommended for surgery. Most were able to initiate treatment. Lack of access to radiation did not significantly increase the proportion of early-stage cancers recommended for hysterectomy.

ABSTRACT

Cervical cancer mortality is high among Peruvian women of reproductive age. Understanding barriers and facilitators of cervical cancer screening and treatment could facilitate development of contextually-relevant interventions to reduce cervical cancer incidence and mortality. From April to October 2019, we conducted a cross-sectional survey with 22 medical personnel and administrative staff from Liga Contra el Cancer, in Lima, Peru. The survey included structured and open-ended questions about participants' roles in cervical cancer prevention and treatment, perceptions of women's barriers and facilitators for getting screened and/or treated for cervical cancer, as well as attitudes towards adopting new cervical cancer interventions. For structured questions, the frequency of responses for each question was calculated. For responses to open-ended questions, content analysis was used to summarize common themes. Our data suggest that the relative importance and nature of barriers that Peruvian women face are different for cervical cancer screening compared to treatment. In particular, participants mentioned financial concerns as the primary barrier to treatment and a lack of knowledge or awareness of human papillomavirus and/or cervical cancer as the primary barrier to screening uptake among women. Participants reported high willingness to adopt new interventions or strategies related to cervical cancer. Building greater awareness about benefits of cervical cancer screening among women, and reducing financial and geographic barriers to treatment may help improve screening rates, decrease late-stage diagnosis and reduce mortality in women who have a pre-cancer diagnosis, respectively. Further studies are needed to generalize study findings to settings other than Lima, Peru.

ABSTRACT

The World Health Organization (WHO) refers to cervical cancer as a public health problem, and sub-Saharan Africa bears the world's highest incidence. In the realm of screening, simplified WHO recommendations for low-resource countries now present an opportunity for a public health approach to this public health problem. We evaluated the feasibility of such a public health approach to cervical cancer screening that features community-based self-administered HPV testing and mobile treatment provision. In two rural districts of western-central Uganda, Village Health Team members led community mobilization for cervical cancer screening fairs in their communities, which offered self-collection of vaginal samples for high-risk human papillomavirus (hrHPV) testing. High-risk human papillomavirus-positive women were re-contacted and referred for treatment with cryotherapy by a mobile treatment unit in their community. We also determined penetrance of the mobilization campaign message by interviewing a probability sample of adult women in study communities about the fair and their attendance. In 16 communities, 2142 women attended the health fairs; 1902 were eligible for cervical cancer screening of which 1892 (99.5%) provided a self-collected vaginal sample. Among the 393 (21%) women with detectable hrHPV, 89% were successfully contacted about their results, of which 86% returned for treatment by a mobile treatment team. Most of the women in the community (93%) reported hearing about the fair, and among those who had heard of the fair, 68% attended. This public health approach to cervical cancer screening was feasible, effectively penetrated the communities, and was readily accepted by community women. The findings support further optimization and evaluation of this approach as a means of scaling up cervical cancer control in low-resource settings.

ABSTRACT

Purpose. In 2018, the US Preventive Services Task Force (USPSTF) endorsed three strategies for cervical cancer screening in women ages 30 to 65: cytology every 3 years, testing for high-risk types of human papillomavirus (hrHPV) every 5 years, and cytology plus hrHPV testing (co-testing) every 5 years. It further recommended that women discuss with health care providers which testing strategy is best for them. To inform such discussions, we used decision analysis to estimate outcomes of screening strategies recommended for women at age 30. Methods. We constructed a Markov decision model using estimates of the natural history of HPV and cervical neoplasia. We evaluated the three USPSTF-endorsed strategies, hrHPV testing every 3 years and no screening. Outcomes included colposcopies with biopsy, false-positive testing (a colposcopy in which no cervical intraepithelial neoplasia grade 2 or worse was found), treatments, cancers, and cancer mortality expressed per 10,000 women over a shorter-than-lifetime horizon (15-year). Results. All strategies resulted in substantially lower cancer and cancer death rates compared with no screening. Strategies with the lowest likelihood of cancer and cancer death generally had higher likelihood of colposcopy and false-positive testing. Conclusions. The screening strategies we evaluated involved tradeoffs in terms of benefits and harms. Because individual women may place different weights on these projected outcomes, the optimal choice for each woman may best be discerned through shared decision making.

ABSTRACT

OBJECTIVE: To identify health systems-level barriers to treatment for women who screened positive for high-risk human papillomavirus (hrHPV) in a cervical cancer prevention program in Kenya. METHODS: In a trial of implementation strategies for hrHPV-based cervical cancer screening in western Kenya in 2018-2019, women underwent hrHPV testing offered through community health campaigns, and women who tested positive were referred to government health facilities for cryotherapy. The current analysis draws on treatment data from this trial, as well as two observational studies that were conducted: 1) periodic assessments of the treatment sites to ascertain availability of resources for treatment and 2) surveys with treatment providers to elicit their views on barriers to care. Bivariate analyses were performed for the site assessment data, and the provider survey data were analyzed descriptively. RESULTS: Seventeen site assessments were performed across three treatment sites. All three sites reported instances of supply stockouts, two sites reported treatment delays due to lack of supplies, and two sites reported treatment delays due to provider factors. Of the 16 providers surveyed, ten (67%) perceived lack of knowledge of HPV and cervical cancer as the main barrier in women's decision to get treated, and seven (47%) perceived financial barriers for transportation and childcare as the main barrier to accessing treatment. Eight (50%) endorsed that providing treatment free of cost was the greatest facilitator of treatment. CONCLUSION: Patient education and financial support to reach treatment are potential areas for intervention to increase rates of hrHPV+ women presenting for treatment. It is also essential to eliminate barriers that prevent treatment of women who present, including ensuring adequate supplies and staff for treatment.

ABSTRACT

It is unknown whether the HPV vaccine is effective in immunocompromised women during catch-up ages. We performed a case-control study of 4,357 women with incident CIN2+ (cases) and 5:1 age-matched, incidence-density selected controls (N = 21,773) enrolled in an integrated health care system from 2006 to 2014. Vaccine effectiveness was estimated from multivariable conditional logistic regression models, with results stratified by immunosuppression history, defined as prior HIV infection, solid organ transplant history, or recently prescribed immunosuppressive medications. HPV vaccination resulted in a 19% reduction in CIN2+ rates for women without an immunosuppression history but a nonsignificant 4% reduction for women with an immunosuppression history. Further research is needed to evaluate whether catch-up HPV vaccine effectiveness varies by immunosuppression status, especially given the recent approval of the HPV vaccine for adults up to 45 years of age.

PURPOSE: Cervical cancer screening is not well implemented in many low- and middle-income countries (LMICs). Mobile health (mHealth) refers to utilization of mobile technologies in health promotion and disease management. We aimed to qualitatively synthesize published articles reporting the impact of mHealth on cervical cancer screening-related health behaviors. METHODS: Three reviewers independently reviewed articles with the following criteria: the exposure or intervention of interest was mHealth, including messages or educational information sent via mobile telephone or e-mail; the comparison was people not using mHealth technology to receive screening-related information, and studies comparing multiple different mHealth interventional strategies were also eligible; the primary outcome was cervical cancer screening uptake, and secondary outcomes included awareness, intention, and knowledge of screening; appropriate research designs included randomized controlled trials and quasi-experimental or observational research; and the study was conducted in an LMIC. RESULTS: Of the 8 selected studies, 5 treated mobile telephone or message reminders as the exposure or intervention, and 3 compared the effects of different messages on screening uptake. The outcomes were diverse, including screening uptake (n = 4); health beliefs regarding the Papanicolaou (Pap) test (n = 1); knowledge of, attitude toward, and adherence to colpocytologic examination (n = 1); interest in receiving messages about Pap test results or appointment (n = 1); and return for Pap test reports (n = 1). CONCLUSION: Overall, our systematic review suggests that mobile technologies, particularly telephone reminders or messages, lead to increased Pap test uptake; additional work is needed to unequivocally verify whether mhealth interventions can improve knowledge regarding cervical cancer. Our study will inform mHealth-based interventions for cervical cancer screening promotion in LMICs.

ABSTRACT

OBJECTIVE: To characterize the efficiency of screening through high-volume community health campaigns (CHCs) by comparing the costs and population reach and identify factors associated with gains in efficiency. Access to effective cervical cancer screening remains limited in low-resource settings, especially in rural areas. Periodic CHCs are a novel method of offering screening for HPV at lower costs and higher population coverage than health facilities. METHODS: A micro-costing study was conducted within a cervical cancer screening trial to measure efficiency (cost per woman screened) and population uptake of HPV-based screening offered through CHCs in Migori County, Kenya between January and September 2016. Regression analysis assessed relationships between population size and efficiency. Structured observations and qualitative interviews identified implementation factors that affected efficiency in individual campaigns. RESULTS: Communities screening through CHCs had costs per woman screened ranging from US $22.06 to $30.21. Efficiency was directly correlated to overall numbers of women screened, but not to proportion of population screened. Modifiable factors that acted as context-specific facilitators and barriers with a potential impact on efficiency were identified. CONCLUSION: There was substantial variation in efficiency among CHCs. Cultural factors, health beliefs, and poor coordination among implementation partners as potential key barriers to screening uptake were identified.

ABSTRACT

In the United States, the historical condemnation and punitive legal consequences of substance use during pregnancy-ranging from incarceration to termination of parental custody of a newborn-render pregnant women in state of biosocial precarity. Yet pregnant women who use illicit substances who desire to parent must generate a legible narrative for bureaucratic groups, such as Child Protective Services, through engagement with biomedical care in order to demonstrate parental capacity. Based on longitudinal interviews with pregnant women who were actively using illicit substances and attempting to parent after delivery, we posit that the relationship between biosocial precarity and biomedical care is a procedural interaction that is rooted in the potential to parent, described as the ability to have a "take-home baby." In order to achieve this goal, the need for engagement in biomedical care and the creation of a biomedical narrative, described as a "résumé for the baby" is required. The relationship between care and biosocial precarity is a unique, underdeveloped concept within medical anthropology and has important consequences not only for the ethical turn within anthropology, but also how applied researchers consider engagement with this highly marginalized, vulnerable population.

ABSTRACT

Detection and treatment of human papillomavirus (HPV) and cervical precancer through screening programs is an effective way to reduce cervical cancer deaths. However, high cervical cancer mortality persists in low- and middle-income countries. As screening programs become more widely available, it is essential to understand how knowledge about cervical cancer and perceived disease risk impacts screening uptake and acceptability. We evaluated women's experiences with a cervical cancer education strategy led by community health volunteers (CHVs) in Migori County, Kenya, as part of a cluster randomized controlled trial of cervical cancer screening implementation strategies. The educational modules employed simple language and images and sought to increase understanding of the relationship between HPV and cervical cancer, the mechanisms of self-collected HPV testing, and the importance of cervical cancer screening. Modules took place in three different contexts throughout the study: (1) during community mobilization; (2) prior to screening in either community health campaigns or health facilities; and (3) prior to treatment. Between January and September 2016, we conducted in-depth interviews with 525 participants to assess their experience with various aspects of the screening program. After the context-specific educational modules, women reported increased awareness of cervical cancer screening and willingness to screen, described HPV- and cervical cancer-related stigma and emphasized the use of educational modules to reduce stigma. Some misconceptions about cervical cancer were evident. With effective and context-specific training, lay health workers, such as CHVs, can help bridge the gap between cervical cancer screening uptake and acceptability.

ABSTRACT

We applied a novel approach to visualizing contraceptive histories from the Demographic and Health Surveys (DHS) contraceptive calendar to elucidate patterns of contraceptive switching and discontinuation (e.g., "churn" in contraceptive use across 2 points in time). Taking the contraceptive calendar from the 2014 Kenya DHS, we used R, an open source statistical programming platform, and the chorddiag package to create interactive chord diagrams to visualize contraceptive use trajectories, including switching and discontinuation, for all contraceptive types queried in the DHS. We present screenshots from the interactive version. We also tested the usefulness of our chord diagram with potential users, including family planning researchers and advocates. Chord diagrams are visually appealing and provide users with the ability to investigate unique patterns in contraceptive discontinuation using publicly available data from the DHS. After receiving a brief orientation to a chord diagram, users found the chord diagram easy to understand and manipulate. The chord diagram is a potentially powerful way for family planning researchers, advocates, and program managers to visualize women's contraceptive trajectories and provides insights into the churn in contraceptive use between 2 discrete time periods.

ABSTRACT

OBJECTIVE: To identify patient factors associated with whether women who screened positive for high-risk human papillomavirus (hrHPV) successfully accessed treatment in a cervical cancer prevention program in Kenya. METHODS: A prospective cohort study was conducted as part of a trial of implementation strategies for hrHPV-based cervical cancer screening in western Kenya from January 2018 to February 2019. In this larger trial, women underwent hrHPV testing during community health campaigns (CHCs), and hrHPV+ women were referred to government facilities for cryotherapy. For this analysis, we looked at rates of and predictors of presenting for treatment and presenting within 30 days of receiving positive hrHPV results ("timely" presentation). Data came from questionnaires completed at the time of screening and treatment. Multivariable logistic regression was used to identify factors associated with each outcome. RESULTS: Of the 505 hrHPV+ women, 266 (53%) presented for treatment. Cryotherapy was performed in 236 (89%) of the women who presented, while 30 (11%) were not treated: 15 (6%) due to gas outage, six (2%) due to pregnancy, five (2%) due to concern for cervical cancer, and four (2%) due to an unknown or other reason. After adjusting for other factors in the multivariable analysis, higher education level and missing work to come to the CHC were associated with presenting for treatment. Variables that were associated with increased likelihood of timely presentation were missing work to come to the CHC, absence of depressive symptoms, told by someone important to come to the CHC, and shorter distance to the treatment site. CONCLUSION: The majority of hrHPV+ women who did not get treated were lost at the stage of decision-making or accessing treatment, with a small number encountering barriers at the treatment sites. Patient education and financial support are potential areas for intervention to increase rates of hrHPV+ women seeking treatment.
