The number of people receiving antiretroviral treatment (ART) has increased considerably in recent years and is expected to continue to grow in the coming years. A major challenge is to maintain uninterrupted supplies of antiretroviral (ARV) drugs and prevent stock outs. This article discusses issues around the management of ARVs and prevention of stock outs in Malawi, a low-income country with a high HIV/AIDS burden, and a weak procurement and supply chain management system. This system for ARVs, paid for by the Global Fund to Fight AIDS, Tuberculosis and Malaria, and bypassing the government Central Medical Stores, is in place, using the United Nations Children’s Fund’s (UNICEF’s) procurement services. The system, managed by a handful of people who spend limited time on supply management, is characterized by a centrally coordinated quantification based on verified data from all national ART clinics, parallel procurement through UNICEF, and direct distribution to ART clinics. The model worked well in the first years of the ART programme with a single first-line ARV regimen, but with more regimens becoming available (e.g., alternative first-line, second-line and paediatric regimens), it has become more difficult to administer. Managing supplies through a parallel system has the advantage that weaknesses in the national system have limited influence on the ARV procurement and supply chain management system. However, as the current system operates without a central warehouse and national buffer stock capacity, it diminishes the ability to prevent ARV stock outs. The process of ordering ARVs, from the time that estimates are made to the arrival of supplies in health facilities, takes approximately one year. Addressing the challenges involved in maintaining ARVs through an efficient procurement and supply chain management system that prevents ARV stock outs through the establishment of a dedicated procurement team, a central warehouse and/or national buffer stock is a priority.

Pharmaceutical products are indispensable for improving health outcomes. An extensive body of work on access to and use of medicines has resulted in an assortment of tools measuring various elements of pharmaceutical systems. Until now however, there has been little attempt to conceptualize a pharmaceutical system as an entity and define its strengthening in a way that allows for measuring systems strengthening. The narrow focus of available tools limits their value in ascertaining which interventions result in stronger, more resilient systems. We sought to address this shortcoming by revisiting the current definitions, frameworks and assessment tools related to pharmaceutical systems. We conducted a comprehensive literature review and consulted with select pharmaceutical experts. On the basis of our review, we propose that a pharmaceutical system consists of all structures, people, resources, processes, and their interactions within the broader health system that aim to ensure equitable and timely access to safe, effective, quality pharmaceutical products and related services that promote their appropriate and cost-effective use to improve health outcomes. We further propose that pharmaceutical systems strengthening is the process of identifying and implementing strategies and actions that achieve coordinated and sustainable improvements in the critical components of a pharmaceutical system to make it more responsive and resilient and to enhance its performance for achieving better health outcomes. Finally, we established that, in addition to system performance and resilience, seven components of the pharmaceutical system are critical for measuring pharmaceutical systems strengthening: pharmaceutical products and related services; policy, laws and governance; regulatory systems; innovation, research and development, manufacturing, and trade; financing; human resources; and information. This work adds clarity to the concept of pharmaceutical systems and their strengthening by proposing holistic definitions on the basis of systems thinking. It provides a practical starting point for measuring the progress of pharmaceutical systems strengthening.

ObjectivesThe objective of this study was to describe the conceptual and implementation approach of selected digital health technologies that were tailored in various resource-constrained countries. To provide insights from a donor-funded project implementer perspective on the practical aspects based on local context and recommendations on future directions.MethodsDrawing from our multi-year institutional experience in more than 20 high disease-burden countries that aspire to meet the 2030 United Nations Sustainable Development Goal 3, we screened internal project documentation on various digital health tools that provide clarity in the conceptual and implementation approach. Taking into account geographic diversity, we provide a descriptive review of five selected case studies from Bangladesh (Asia), Mali (Francophone Africa), Uganda (East Africa), Mozambique (Lusophone Africa), and Namibia (Southern Africa).FindingsA key lesson learned is to harness and build on existing governance structures. The use of data for decision-making at all levels needs to be cultivated and sustained through multi-stakeholder partnerships. The next phase of information management development is to build systems for triangulation of data from patients, commodities, geomapping, and other parameters of the pharmaceutical system. A well-defined research agenda must be developed to determine the effectiveness of the country- and regional-level dashboards as an early warning system to mitigate stock-outs and wastage of medicines and commodities.ConclusionThe level of engagement with users and stakeholders was resource-intensive and required an iterative process to ensure successful implementation. Ensuring user acceptance, ownership, and a culture of data use for decision-making takes time and effort to build human resource capacity. For future United Nations voluntary national reviews, countries and global stakeholders must establish appropriate measurement frameworks to enable the compilation of disaggregated data on Sustainable Development Goal 3 indicators as a precondition to fully realize the potential of digital health technologies.

The response to emergency public health challenges such as HIV, TB, and malaria has been successful in mobilising resources and scaling up treatment for communicable diseases. However, many of the remaining challenges in improving access to and appropriate use of medicines and services require pharmaceutical systems strengthening. Incorporating pharmaceutical systems strengthening into global health programmes requires recognition of a few 'truths'. Systems strengthening is a lengthy and resource-intensive process that requires sustained engagement, which may not align with the short time frame for achieving targets in vertical-oriented programmes. Further, there is a lack of clarity on what key metrics associated with population and patient level outcomes should be tracked for systems strengthening interventions. This can hinder advocacy and communication with decision makers regarding health systems investments. Moving forward, it is important to find ways to balance the inherent tensions between the short-term focus on the efficiency of vertical programmes and broader, longer-term health and development objectives. Global health programme design should also shift away from a narrow view of medicines primarily as an input commodity to a more comprehensive view that recognizes the various structures and processes and their interactions within the broader health system that help ensure access to and appropriate use of medicines and related services.
