Inadequate care within Tanzania's primary health system contributes to thousands of preventable maternal and child deaths, and unwanted pregnancies each year. A key contributor is lack of coordination between three primary healthcare actors: public sector Community Health Workers (CHWs) and health facilities, and private sector Accredited Drug Dispensing Outlets (ADDOs). The Afya-Tek program aims to improve the continuity of care amongst these actors in Kibaha district, through a mobile-application based digital referral system that focuses on improving maternal, child and adolescent health. The digital system called Afya-Tek was co-created with users and beneficiaries, and utilises open-source technology in-line with existing government systems. The system guides healthcare actors with individualised decision support during client visits and recommends accurate next steps (education, treatment, or referral). From July 2020 to June 2023, a total of 241,000 individuals were enrolled in the Afya-Tek program covering 7,557 pregnant women, 6,582 postpartum women, 45,900 children, and 25,700 adolescents. CHWs have conducted a total of 626,000 home visits to provide health services, including screening clients for danger signs. This has resulted in 38,100 referrals to health facilities and 24,300 linkages to ADDOs. At the ADDO level, 48,552 clients self-presented; 33% of children with pneumonia symptoms received Amoxicillin; 34% of children with diarrhoea symptoms received ORS and zinc; and 4,203 referrals were made to nearest health facilities. Adolescents preferred services at ADDOs as a result of increased perceived privacy and confidentiality. In total, 89% of all referrals were attended by health facilities. As the first digital health program in Tanzania to demonstrate the linkage among public and private sector primary healthcare actors, Afya-Tek holds promise to improve maternal, child and adolescent health as well as for scale-up and sustainability, through incorporation of other disease conditions and integration with government's Unified Community System (UCS)., (© 2024.

Introduction: Tanzania is among the African countries which started COVID-19 vaccination late (August 2021) compared to other countries in the African continent. By mid-March 2022, overall vaccine uptake was 13% of the targeted population, which was very low compared to other countries. We describe the contribution of champions in the Rukwa region that led to an increase in vaccine coverage rate in Tanzania., Methods: a community-based campaign was conducted using community champions from July 15th to August 31st, 2022. A baseline assessment was conducted focusing on the key drivers, barriers, and enablers for COVID-19 vaccine uptake in the region. A working session to develop IEC materials and messages tailored to addressing the issues raised in the community to be used in the campaign in the region was conducted, followed by the campaign's launch. Community engagement and sensitizations, which contributed to the rise of vaccinated people, were based on house-to-house visits, village meetings, and visiting community gatherings such as marketplaces, places of worship, and sports areas, which were done by champions alongside vaccinators., Results: the campaign contributed to the increase of vaccination coverage because, before the start of the campaign, the vaccination coverage was 10% as of July 14th, 2022. After the campaign, which started on July 15th to August 31st, 2022, the coverage increased by 12%. During the post-evaluation exercise after the campaign, the coverage keeps increased and reached 94% by October 2022. The coverage kept increasing even after the intervention's end due to the campaign's positive effect., Conclusion: the community still needs correct information to avoid misinformation and hesitancy, especially when introducing new disease response mechanisms such as vaccines. The community champions who are based in the community play a critical role in addressing community concerns and contribute to the effectiveness of the implementation; hence sustainability is crucial., Competing Interests: The authors declare no competing interests., (©Erick Msunyaro et al.)
