Acceptability of an integrated school-based HPV vaccination program within two districts of Tanzania: A qualitative descriptive study.

Tanzania has one of the highest cervical cancer incidence and mortality rates in sub-Saharan Africa. The Tanzanian Ministry of Health developed an integrated adolescent health program, HPV-Plus, that combines HPV vaccination with additional health services: nutritional assessments, vision screening, and vaccination for adolescent girls, and education for all genders. This qualitative descriptive study evaluated the acceptability of the HPV-Plus program in two districts in Tanzania. Key informants comprising of adolescent girls, parents, program planners, and program implementers in Njombe and Dar es Salaam Tanzania were interviewed to assess the program acceptability. Transcripts were analyzed using a team-based iterative thematic analysis approach, consisting of both inductive and deductive coding. The Theoretical Framework of Acceptability was used to guide analysis, with themes categorized according to theoretical constructs of intervention coherence, affective attitudes and perceptions, and perceived effectiveness. Overall acceptability of the HPV-Plus program was high among stakeholders. The most salient finding regarding factors that influenced HPV vaccine acceptability was largely related to education and knowledge levels surrounding the HPV, cervical cancer, and HPV vaccines. The educational component of the HPV-Plus program was key in increasing acceptability. Parents reported the lowest acceptability towards the program. This was found to be primarily due to perceptions of not being sufficiently engaged throughout program implementation. Increasing acceptability of HPV vaccination programs among key stakeholders is critical to facilitating vaccine uptake and meeting vaccination coverage targets. Our results demonstrate that the inclusion of a comprehensive education component within the HPV-Plus program was key in facilitating HPV vaccine acceptability amongst stakeholders.

Feasibility and sustainability of a school-based platform for integrated delivery of HPV vaccination with adolescent health services in Tanzania: qualitative insights from stakeholders.

To meet lofty human papillomavirus (HPV) immunization goals in Tanzania, the Ministry of Health integrated HPV vaccination with adolescent health services using a school-based approach. A qualitative study was conducted in June-July 2021, examining the feasibility and sustainability of an integrated service package, HPV Plus. In-depth interviews with 46 programme implementers (i.e. health-care workers and teachers) and planning stakeholders (i.e. government officials and school administrators) in Dar es Salaam and Njombe Regions explored enablers and constraints to HPV Plus programme implementation, including resource and staffing requirements. Two facilitators and three barriers to HPV Plus feasibility and sustainability were identified from thematic analysis of interviews. Interviewed stakeholders emphasized the programme's feasibility, especially if the efficiencies offered by a school-based platform were optimized. Implementation facilitators included (1) optimized service delivery efficiency through a school-based platform and (2) resources saved by combining adolescent health services and HPV immunization into a single programme package. Key barriers to HPV Plus feasibility and sustainability were (1) time, space and resource constraints (e.g. commodity stockouts and challenges delivering the complete service package to large cohorts of students within allotted times); (2) human resource gaps and increased workloads within the health workforce and (3) insufficient referral mechanisms linking schools to health facilities. Scaling up HPV Plus will require proactive commodity procurement and security; resource mobilization to reach ambitious service delivery targets and close co-ordination of programme implementation with school administrators.

Integration of other services with human papillomavirus vaccination; lessons from earlier in the life course highlight the need for new policy and implementation evidence.

Integration of vaccination against human papillomavirus (HPV) with other essential health services for adolescents has been proposed in global strategies and tested in demonstration projects in low- and middle-income countries (LMIC). Published experiences, global guidance, and one key example, the implementation of "HPV Plus" in Tanzania, all demonstrate the need for greater operational evidence to guide future implementation and policy. Review of experiences earlier in the life course, integrating post-partum family planning with infant immunization, show lessons from 13 LMICs that can apply to provision of adolescent health information and services alongside HPV vaccination. Three distinct models of integration emerge from this review comprising: 1) multiple tasks and functions by health staff providing vaccination and other care, or 2) secondary tasks added to the main function of vaccination, or 3) co-location of matched services provided by different staff. These models, with strengths and weaknesses demonstrated in family planning and immunization experiences, apply in different ways to the three main platforms used for HPV vaccination: school, facility or community. For HPV vaccination policy and programming, an initial need is to combine the existing evidence on vaccine service delivery - including coverage, efficiency, cost, and cost-effectiveness information - with what is known on how integration works in practice; the operational detail and models employed. This synthesis may enable assessment which models best suit the different service delivery platforms. An additional need is to link this with more tailored local assessments of the adolescent burden of disease and other determinants of their well-being to develop new thinking on what can and cannot be done to integrate other services alongside HPV vaccination. New approaches placing adolescents at the center are needed to design services tailored to their preferences and needs. The potential synergies with cervical cancer screening and treatment for older generations of women, also require further exploration. Coordinated action aligning HPV vaccination with broader adolescent health and wellbeing will generate social, economic and demographic benefits, which in themselves are sufficient justification to devote more attention to integrated approaches.

National introduction of human papillomavirus (HPV) vaccine in Tanzania: Programmatic decision-making and implementation.

BACKGROUND: Cervical cancer is the leading cause of cancer among women in Tanzania, with approximately 10,000 new cases and 7,000 deaths annually. In April 2018, the Government of Tanzania introduced 2 doses of human papillomavirus (HPV) vaccine nationally to adolescent girls to prevent cervical cancer, following a successful 2-year pilot introduction of the vaccine in the Kilimanjaro Region. METHODS: We interviewed key informants at the national level in Tanzania from February to November 2019, using a semi-structured tool to better understand national decision-making and program implementation. We conducted a comprehensive desk review of HPV vaccine introduction materials and reviewed administrative coverage data. RESULTS: Ten key informants were interviewed from the Ministry of Health, Community Development, Gender, Elderly, and Children, the World Health Organization, and other partners, and HPV vaccine planning documents and administrative coverage data were reviewed during the desk review. Tanzania introduced HPV vaccine to a single-age cohort of 14-year-old girls, with the decision-making process involving the Tanzania Immunization Technical Advisory Group and the national Interagency Coordination Committee. HPV vaccine was integrated into the routine immunization delivery strategy, available at health facilities and through outreach services at community sites, community mobile sites (>10 km from the health facility), and primary and secondary schools. Pre-introduction activities included trainings and microplanning workshops for health workers and school personnel at the national, regional, council, and health facility levels. Over 6,000 health workers and 22,000 school personnel were trained nationwide. Stakeholder and primary health care committee meetings were also conducted at the national level and in each of the regions as part of the advocacy and communication strategy. Administrative coverage of the first dose of HPV vaccine at the end of 2019 was 78%, and second dose coverage was 49%. No adverse events following HPV vaccination were reported to the national level. DISCUSSION: Tanzania successfully introduced HPV vaccine nationally targeting 14-year-old girls, using routine delivery strategies. Continued monitoring of vaccination coverage will be important to ensure full 2-dose vaccination of eligible girls. Tanzania can consider periodic intensified vaccination and targeted social mobilization efforts, as needed.

Evaluation of a Smartphone-Based Training Strategy Among Health Care Workers Screening for Cervical Cancer in Northern Tanzania: The Kilimanjaro Method.

PURPOSE: Almost nine of 10 deaths resulting from cervical cancer occur in low-income countries. Visual inspection under acetic acid (VIA) is an evidence-based, cost-effective approach to cervical cancer screening (CCS), but challenges to effective implementation include health provider training costs, provider turnover, and skills retention. We hypothesized that a smartphone camera and use of cervical image transfer for real-time mentorship by experts located distantly across a closed user group through a commercially available smartphone application would be both feasible and effective in enhancing VIA skills among CCS providers in Tanzania. METHODS: We trained five nonphysician providers in semirural Tanzania to perform VIA enhanced by smartphone cervicography with real-time trainee support from regional experts. Deidentified images were sent through a free smartphone application on the available mobile telephone networks. Our primary outcomes were feasibility of using a smartphone camera to perform smartphone-enhanced VIA and level of agreement in diagnosis between the trainee and expert reviewer over time. RESULTS: Trainees screened 1,072 eligible women using our methodology. Within 1 month of training, the agreement rate between trainees and expert reviewers was 96.8%. Providers received a response from expert reviewers within 1 to 5 minutes 48.4% of the time, and more than 60% of the time, feedback was provided by regional expert reviewers in less than 10 minutes. CONCLUSION: Our method was found to be feasible and effective in increasing health care workers' skills and accuracy. This method holds promise for improved quality of VIA-based CCS programs among health care providers in low-income countries.

Expanding Cervical Cancer Screening and Treatment in Tanzania: Stakeholders' Perceptions of Structural Influences on Scale-Up.

UNLABELLED: Tanzania has the highest burden of cervical cancer in East Africa. This study aims to identify perceived barriers and facilitators that influence scale-up of regional and population-level cervical cancer screening and treatment programs in Tanzania. Convenience sampling was used to select participants for this qualitative study among 35 key informants. Twenty-eight stakeholders from public-sector health facilities, academia, government, and nongovernmental organizations completed in-depth interviews, and a seven-member municipal health management team participated in a focus group discussion. The investigation identified themes related to the infrastructure of health services for cervical cancer prevention, service delivery, political will, and sociocultural influences on screening and treatment. Decentralizing service delivery, improving access to screening and treatment, increasing the number of trained health workers, and garnering political will were perceived as key facilitators for enhancing and initiating screening and treatment services. In conclusion, participants perceived that system-level structural factors should be addressed to expand regional and population-level service delivery of screening and treatment. IMPLICATIONS FOR PRACTICE: Tanzanian women have a high burden of cervical cancer. Understanding the perceived structural factors that may influence screening coverage for cervical cancer and availability of treatment may be beneficial for program scale-up. This study showed that multiple factors contribute to the challenge of cervical cancer screening and treatment in Tanzania. In addition, it highlighted systematic developments aimed at expanding services. This study is important because the themes that emerged from the results may help inform programs that plan to improve screening and treatment in Tanzania and potentially in other areas with high burdens of cervical cancer.

Integrating HIV testing into cervical cancer screening in Tanzania: an analysis of routine service delivery statistics.

BACKGROUND: While the lifetime risk of developing cervical cancer (CaCx) and acquiring HIV is high for women in Tanzania, most women have not tested for HIV in the past year and most have never been screened for CaCx. Good management of both diseases, which have a synergistic relationship, requires integrated screening, prevention, and treatment services. The aim of this analysis is to assess the acceptability, feasibility and effectiveness of integrating HIV testing into CaCx prevention services in Tanzania, so as to inform scale-up strategies. METHODS: We analysed 2010-2013 service delivery data from 21 government health facilities in four regions of the country, to examine integration of HIV testing within newly introduced CaCx screening and treatment services, located in the reproductive and child health (RCH) section of the facility. Analysis included the proportion of clients offered and accepting the HIV test, reasons why testing was not offered or was declined, and HIV status of CaCx screening clients. RESULTS: A total of 24,966 women were screened for CaCx; of these, approximately one-quarter (26%) were referred in from HIV care and treatment clinics. Among the women of unknown HIV status (n = 18,539), 60% were offered an HIV test. The proportion of women offered an HIV test varied over time, but showed a trend of decline as the program expanded. Unavailability of HIV test kits at the facility was the most common reason for a CaCx screening client not to be offered an HIV test (71% of 6,321 cases). Almost all women offered (94%) accepted testing, and 5% of those tested (582 women) learned for the first time that they were HIV-positive. CONCLUSION: Integrating HIV testing into CaCx screening services was highly acceptable to clients and was an effective means of reaching HIV-positive women who did not know their status; effectiveness was limited, however, by shortages of HIV test kits at facilities. Integration of HIV testing into CaCx screening services should be prioritized in HIV-endemic settings, but more work is needed to eliminate logistical barriers. The coverage of CaCx screening among HIV care and treatment-enrolled women in Tanzania may be low and should be examined.
