RESUMO

BACKGROUND: Pregnancy-related anaemia is a public health challenge across Africa. Over 50% of pregnant women in Africa get diagnosed with this condition, and up to 75% of these are caused by iron deficiency. The condition is a significant contributor to the high maternal deaths across the continent and, in particular, Nigeria, which accounts for about 34% of global maternal deaths. Whereas oral iron is the mainstay treatment for pregnancy-related anaemia in Nigeria, this treatment is not very effective given the slow absorption of the medication, and its gastrointestinal adverse effects which lead to poor compliance by women. Intravenous iron is an alternative therapy which can rapidly replenish iron stores, but fears of anaphylactic reactions, as well as several misconceptions, have inhibited its routine use. Newer and safer intravenous iron formulations, such as ferric carboxymaltose, present an opportunity to overcome some concerns relating to adherence. Routine use of this formulation will, however, require addressing misconceptions and systemic barriers to adoption in the continuum of care of obstetric women from screening to treatment. This study aims to test the options to strengthen routine screening for anaemia during and immediately after pregnancy, as well as evaluate and improve conditions necessary to deliver ferric carboxymaltose to pregnant and postpartum women with moderate to severe anaemia. METHODS: This study will be conducted in a cluster of six health facilities in Lagos State, Nigeria. The study will employ continuous quality improvement through the Diagnose-Intervene-Verify-Adjust framework and Tanahashi's model for health system evaluation to identify and improve systemic bottlenecks to the adoption and implementation of the intervention. Participatory Action Research will be employed to engage health system actors, health services users, and other stakeholders to facilitate change. Evaluation will be guided by the consolidated framework for implementation research and the normalisation process theory. DISCUSSION: We expect the study to evolve transferable knowledge on barriers and facilitators to the routine use of intravenous iron that will inform scale-up across Nigeria, as well as the adoption of the intervention and strategies in other countries across Africa.

RESUMO

BACKGROUND: Short Message Service (SMS) reminders have improved vaccine uptake in low- and middle-income countries (LMICs). However, the limited use of SMS reminders in LMICs requires evaluating the intervention's internal and external validity to improve adoption and sustainability. Using the Reach, Effectiveness, Adoption, Implementation, and Maintenance (RE-AIM) framework, we qualitatively assessed the impact of a SMS reminder intervention implemented in Kebbi State, Northwest Nigeria between May 20, 2019 and May 31, 2020. This will guide and inform future SMS reminder interventions to improve childhood immunization uptake in LMICs. METHODS: In June 2020, we conducted 14 focus group discussions, 13 in-depth interviews, and 20 key informant interviews among 144 purposively selected participants from five local government areas of Kebbi State. For analysis, we used a deductive approach to develop preliminary codes based on the RE-AIM framework and the inductive approach to generate themes that emerged from the interviews. RESULTS: The perceived importance and impact of the SMS reminder in improving demand and uptake for vaccinations were the consistent contributing factors that encouraged participants' participation. Other facilitators included the involvement of health workers in supporting SMS reminder registration and community gatekeepers using existing structures to convey messages on scheduled immunization services. Policymakers adopted the intervention because it aligns with the state's priority to improve immunization coverage. Similarly, the SMS reminder appealed to health workers and program managers because it reduced their workload and served as a performance monitoring tool to track immunization and intervention defaulters. Despite these, low mobile phone ownership and the inability to read text messages due to the low literacy level were the main barriers during implementation. Finally, data availability on cost-effectiveness and the intervention's impact on improving coverage was critical for scalability. CONCLUSIONS: Our study demonstrated that SMS reminders in local languages could improve vaccination demand and uptake in resource-constrained settings due to their perceived importance and impact. Addressing the cited implementation barriers and promoting the facilitators is critical to its adoption and sustainability. Costing and impact data are needed to collaborate findings on the effectiveness of the SMS reminder to improve childhood vaccination uptake.

RESUMO

INTRODUCTION: COVID-19 vaccine hesitancy is a worldwide phenomenon and a serious threat to pandemic control efforts. Until recently, COVID-19 vaccine hesitancy was not the cause of low vaccine coverage in Nigeria; vaccine scarcity was the problem. As the global supply of COVID-19 vaccines improves in the second half of 2021 and more doses are deployed in Nigeria, the supply/demand dynamic will switch. Vaccine acceptance will become a key driver of coverage; thus, amplifying the impact of vaccine hesitancy. Conspiracy theories and misinformation about COVID-19 are rampant and have been shown to drive vaccine hesitancy and refusal. This study systematically elicits the misinformation and conspiracy theories circulating about COVID-19 among the Nigerian public to understand relevant themes and potential message framing for communication efforts to improve vaccine uptake. METHODS: From February 1 to 8, 2021, we conducted 22 focus group discussions and 24 key informant interviews with 178 participants from six states representing the six geopolitical zones. Participants were purposively selected and included sub-national program managers, healthcare workers, and community members. All interviews were iteratively analyzed using a framework analysis approach. RESULTS: We elicited a total of 33 different conspiracy theories or misinformation that participants had heard about the COVID-19 virus, pandemic response, or vaccine. All participants had heard some misinformation. The leading claim was that COVID-19 was not real, and politicians took advantage of the situation and misused funds. People believed certain claims based on distrust of government, their understanding of Christian scripture, or their lack of personal experience with COVID-19. CONCLUSIONS: Our study is the first to report a thematic analysis of the range of circulating misinformation about COVID-19 in Nigeria. Our findings provide new insights into why people believe these theories, which could help the immunization program improve demand generation communication for COVID-19 vaccines by targeting unsubstantiated claims.

RESUMO

INTRODUCTION: Self-collection of samples for HPV testing may increase women's access to cervical cancer screening in low- and middle-income settings. However, implementation remains poor in many regions. The purpose of this systematic review was to examine implementation data from randomized controlled trials evaluating human papillomavirus (HPV) self-collection testing among women in sub-Saharan Africa using the RE-AIM (Reach, Efficacy/Effectiveness, Adoption, Implementation, and Maintenance) framework. METHODS: We searched four electronic databases (PubMed, CINAHL, Web of Science, and Global Health) for pragmatic randomized controlled trials that promote HPV self-collection among women in sub-Saharan Africa. Study selection and data extraction were conducted according to the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-analyses) checklist. Two researchers independently extracted information from each article using a RE-AIM data extraction tool. The reporting of RE-AIM dimensions was summarized and synthesized across included interventions. RESULTS: We identified 2008 citations, and eight studies were included. These reported on five unique interventions. The five interventions were conducted in five countries: Cameroon, Ethiopia, Kenya, Nigeria, and Uganda. Intervention reach (80%) was the most commonly reported RE-AIM dimension, followed by adoption (56%), efficacy/effectiveness (52%), implementation (47%), and maintenance (0%). All the interventions described increased uptake of HPV testing among study participants (effectiveness). However, the majority of the studies focused on reporting internal validity indicators such as inclusion criteria (100%) and exclusion criteria (100%), and few reported on external validity indicators such as participation rate (40%), intervention cost (40%), staff selection (20%), and cost of maintenance (0%). CONCLUSIONS: Our review highlights the under-reporting of external validity indicators such as participation rate, intervention, and maintenance costs in studies of self-collection for HPV testing among women in SSA. Future research should focus on including factors that highlight internal validity factors and external validity factors to develop a greater understanding of ways to increase not only reach but also implementation and long-term maintenance of these interventions. Such data may advance the translation of HPV interventions into practice and reduce health disparities in SSA. Findings highlight the need for innovative tools such as participatory learning approaches or open challenges to expand knowledge and assessment of external validity indicators to ultimately increase the uptake of HPV testing among women in SSA.

RESUMO

BACKGROUND: Penta3 coverage in Nigeria was low at 33 % in 2017. The most reported reason for non-vaccination was lack of knowledge about the immunization place, time, and need. To address knowledge gaps and improve vaccination uptake, we designed an Immunization Reminder and Information SMS System (IRISS) to educate and remind parents/caregivers about immunization using SMS. A formative study was conducted to understand the contextual and behavioural factors that would inform the IRISS intervention design and implementation. METHODS: We conducted the study in four Local Government Areas (LGAs) of Kebbi State Nigeria in October 2018, amongst a diverse selection of participants. Data on social norms about vaccinations, barriers to immunization uptake, mobile phone use, SMS message testing, and willingness to accept SMS reminders were collected from focus group discussions (N = 11), in-depth interviews (N = 12), and key informant interviews (N = 13). In addition, we assessed 33 messages covering schedule reminders, normative, motivational, educational, and informative contents for clarity, comprehensibility, relevance, cultural appropriateness, and ability to motivate action among community members from Argungu and Fakai LGAs. All interviews were analyzed using a thematic analysis approach. RESULTS: We interviewed 135 people, and 90 % were community members. While we found positive perceptions about immunizations among those interviewed, pockets of misconceptions existed among community members. Lack of awareness on the importance of vaccination was a consistent reason for under-vaccination across the LGAs. In addition, most community members do not own phones, could not read SMS messages, and were unaware of how to check/open text messages received. Despite concerns about low literacy levels and phone ownership, community members still saw a role in SMS reminders when phone owners receive messages. For instance, community leaders can disseminate said messages to community members through existing channels such as town announcers and religious gatherings. Therefore, the SMS becomes a source of information, with phone owners acting as a conduit to community dissemination mechanisms. We generally found the tested messages to be relevant, motivating, and culturally acceptable. CONCLUSIONS: SMS reminders have the potential to bridge the information gap in community awareness for vaccination, which can translate to improved immunization uptake. In rural communities with low literacy levels and phone ownership, immunization information can be disseminated when existing community leadership structures are engaged.

RESUMO

Pneumonia is the leading cause of child deaths in Nigeria. Interventions to combat pneumonia are known and globally available, but not yet deployed effectively in Nigeria. While the under-five pneumonia deaths dropped globally by 51% during the Millennium Development Goals (MDG) years (2000 to 2015), the rate declined by a mere 8% in Nigeria. In this commentary, we focus on three factors that may have stalled Nigeria's progress on pneumonia control. First, a chronically weak health system failed to deliver the needed services at scale. Second, strong coordination of a multipronged and well-funded push against pneumonia was absent. Third, sound and timely data on pneumonia intervention coverage were lacking, thus blunting the accountability mechanisms that could have driven quick, targeted action. In response, the Federal Ministry of Health recently developed a National Pneumonia Control Strategy with the support of the "Every Breath Counts Coalition" (EBCC). This strategy, a first of its kind, articulates a common vision for reducing pneumonia-led morbidity and mortality and provides a unified approach to respond comprehensively to pneumonia within and outside the health sector. Strong political will and sustainable financing are now needed to effectively implement this strategy and accelerate progress on pneumonia control. This will contribute hugely to achieving the government's health goals, the Sustainable Development Goal (SDG) 3.2 and the Global Action Plan on Pneumonia and Diarrhoea (GAPPD) targets.

RESUMO

INTRODUCTION: Vaccination coverage is low in Nigeria, partly due to poor demand for the vaccines. Till date, there is limited understanding of what works to improve demand for vaccination. A Vaccine Indicator and Reminder (VIR) band was designed to be worn on a child's ankle to serve as a constant reminder to parents/caregivers on when to bring their children for vaccinations. This study assessed the acceptability of the band as a wearable reminder for infant vaccination in Kebbi State, Nigeria. METHODS: A total of 503 infants who met the eligibility criteria were enrolled between August 2017 and February 2018. The intervention involved 1) sensitisation and mobilisation of community gatekeepers to advocate for immunisation; 2) engaging traditional birth attendants (TBAs) to refer mothers for vaccination and VIR bands; and 3) training facility-based health workers to secure the band on an eligible child. Focus group discussions and in-depth interviews were conducted at baseline (May 2016) and end-line (July 2018) with purposively selected participants. These interviews were analysed thematically. RESULTS: There was general acceptability of the band at all levels, especially among community members who likened it to a "wristwatch" that constantly reminds mothers when next to vaccinate their children. The strong support from community leaders, TBAs and participating health workers increased acceptability of the band. Similarly, the VIR band's aesthetics, ease of use and perceived benefits contributed to its acceptability. Wearing the VIR band was not perceived as an impediment because similar accessories are worn on new-borns. However, there were concerns about wearing accessories on the ankle, the red indicator colour, and the malfunctioning of some bands. CONCLUSIONS: This study demonstrates that cultural adaptability of interventions and engagement with community structures are important in facilitating acceptability of new innovations. Further studies will evaluate the effectiveness of VIR band in improving vaccination coverage.
