Health System Considerations for Community-Based Implementation of Automated Respiratory Counters to Identify Childhood Pneumonia in 5 Regions of Ethiopia: A Qualitative Study.

BACKGROUND: In Ethiopia, childhood pneumonia is diagnosed in primary healthcare settings by measuring respiratory rate (RR) along with the presence of cough, chest indrawing, difficulty breathing, and fast breathing. Our aim was to identify health system-level lessons from implementing two automated RR counters, Children's Automated Respiration Monitor (ChARM) by Phillips® and Rad-G by Masimo®, to provide considerations for integrating such devices into child health programmes and health systems. This study was part of an initiative called the Acute Respiratory Infection Diagnostic Aids (ARIDA). METHODS: Key informant interviews (KIIs) were conducted with 57 participants (health workers in communities and facilities, trainers of health workers, district management, and key decision-makers) in five regions of Ethiopia. Data were analyzed in ATLAS.ti using thematic content analysis and themes were categorized using the Tanahashi bottleneck analysis. RESULTS: All participants recommended scaling up the ARIDA initiative nationally as part of Integrated Management of Newborn and Childhood Illness (IMNCI) in primary healthcare. Health workers perceived the devices as: time saving, acceptable by parents and children, and facilitating diagnosis and referrals. Health workers perceived an increased demand for services and reduced numbers of sick children not seeking care. Participants recommended increasing the number of devices distributed and health workers trained. Strengthening drug supply chains, improving oxygen gas availability, and strengthening referral networks would maximize perceived benefits. While training improved knowledge, more supportive supervision, integration with current guidelines and more guidance related to community engagement was recommended. CONCLUSION: Automatic RR counters for the decentralized diagnosis of childhood pneumonia could have positive impact on improving the quality of diagnosis and management of pneumonia in children. However, the study has shown that a health system approach is required to ensure all steps along the pneumonia pathway are adequate, including drug and oxygen supply, community engagement, health worker training and support, and referral pathways.

Accelerating the development of vaccine microarray patches for epidemic response and equitable immunization coverage requires investment in microarray patch manufacturing facilities.

INTRODUCTION: There is a need for investment in manufacturing for vaccine microarray patches (vMAPs) to accelerate vMAP development and access. vMAPs could transform vaccines deployment and reach to everyone, everywhere. AREAS COVERED: We outline vMAPs' potential benefits for epidemic preparedness and for outreach in low- and lower-middle-income countries (LMICs), share lessons learned from pandemic response, and highlight that investment in manufacturing-at-risk could accelerate vMAP development. EXPERT OPINION: Pilot manufacturing capabilities are needed to produce clinical trial material and enable emergency response. Funding vMAP manufacturing scale-up in parallel to clinical proof-of-concept studies could accelerate vMAP approval and availability. Incentives could mitigate the risks of establishing multi-vMAP manufacturing facilities early.

Strategies for vaccine-product innovation: Creating an enabling environment for product development to uptake in low- and middle-income countries.

Vaccine-product innovations that address barriers to immunization are urgently needed to achieve equitable vaccine coverage, as articulated in the new Immunization Agenda 2030 and the Gavi 5.0 strategy. In 2020, the Vaccine Innovation Prioritisation Strategy (VIPS) prioritized three innovations, namely microarray patches (MAPs), heat-stable and controlled-temperature chain (CTC) enabled liquid vaccine formulations and barcodes on primary packaging. These innovations were prioritized based on the priority immunization barriers that they may help overcome in resource constrained contexts, as well as by considering their potential impact on health, coverage and equity, safety, economic costs and their technical readiness and commercial feasibility. VIPS is now working to accelerate the development and lay the foundation for future uptake of the three priority vaccine-product innovations, with the long term-goal to ensure equitable vaccine coverage and increased impact of vaccines in low- and middle- income countries. To inform our strategic planning, we analyzed four commercially available vaccine product-innovations and conducted interviews with individuals from 17 immunization organizations, and/or independent immunization experts. The findings are synthesized into an 'innovation conundrum' that describes the challenges encountered in developing vaccine-product innovations and a vaccine-product innovation 'theory of change', which highlights actions that should be undertaken in parallel to product development to incentivize sustainable investment and prepare the pathway for uptake and impact.
