- Evidence-based public health: not only whether it works, but how it can be made to work practicably at scale
Because public health must operate at scale in widely diverse, complex situations, randomized controlled trials (RCTs) have limited utility for public health. Other methodologies are needed. A key conceptual backbone is a detailed “theory of change” to apply appropriate evidence for each operational component. Synthesizing patterns of findings across multiple methodologies provides key insights. Programs operating successfully across a variety of settings can provide some of the best evidence. Challenges include judging the quality of such evidence and assisting programs to apply it. WHO and others should shift emphasis from RCTs to more relevant evidence when assessing public health issues.
- Using Qualitative Methods to Validate and Contextualize Quantitative Findings: A Case Study of Research on Sexual Behavior and Gender-Based Violence Among Young Swazi Women
Nesting qualitative data collection methods within quantitative studies improves results by assessing validity and providing depth and context. Using data from 3 sources from Swaziland, we triangulate qualitative and quantitative findings to highlight how different methodologies produce discrepant data regarding risky sexual behaviors among young women. We found that women reported similar numbers of lifetime sex partners in all sources, but the proportion reporting multiple and concurrent partnerships was several times higher in qualitative interviews. In addition, qualitative data can provide deeper understanding of how participants, such as those experiencing gender-based violence, understood the experiences behind the quantitative statistics.
- A False Dichotomy: RCTs and Their Contributions to Evidence-Based Public Health
Global public health should rely on those research methods that best answer the pressing questions at hand. Randomized controlled trials (RCTs) and other rigorous impact evaluation methods have a critical role to play in public health.
- A Global Learning Agenda for the Levonorgestrel Intrauterine System (LNG IUS): Addressing Challenges and Opportunities to Increase Access
The LNG IUS is one of the most effective forms of reversible contraception and has important noncontraceptive benefits but is currently not used at scale in any Family Planning 2020 focus country. A global working group developed a shared learning agenda to answer critical questions, harmonize approaches, avoid duplication, and facilitate introduction of the method within the context of informed choice.
- mLearning in the Democratic Republic of the Congo: A Mixed-Methods Feasibility and Pilot Cluster Randomized Trial Using the Safe Delivery App
Health worker knowledge and self-confidence in basic emergency obstetric and newborn care (BEmONC) increased significantly 3 months after introduction of the Safe Delivery App in intervention facilities compared with controls.
- What Does It Take to Be an Effective National Steward of Digital Health Integration for Health Systems Strengthening in Low- and Middle-Income Countries?
A purposeful literature review of peer-reviewed and gray literature identified 4 broad thematic areas of digital health stewardship—strategic direction, policies and procedures, roles and responsibilities, and health service delivery—that need further research and development in order for digital health to be better positioned to positively impact low- and middle-income country health systems.
- mHealth for Tuberculosis Treatment Adherence: A Framework to Guide Ethical Planning, Implementation, and Evaluation
Promising mHealth approaches for TB treatment adherence include:
Video observation
Patient- or device-facilitated indirect monitoring
Direct monitoring through embedded sensors or metabolite testing
To mitigate ethical concerns, our framework considers accuracy of monitoring technologies, stigmatization and intrusiveness of the technologies, use of incentives, and the balance of individual and public good.
- A New World Health Era
Unprecedented economic progress and demands for social protection have engendered an economic transition in health in many low- and middle-income countries, characterized by major increases in domestic health spending and growing national autonomy. At the global level, development assistance is refocusing on fragile states, the poorest communities, and cooperation on global public goods like health security, technical norms, and innovation. Intergovernmental organizations like WHO need the wherewithal and support to provide leadership and to properly advance this new world health era.
- Development and use of a master health facility list: Haiti's experience during the 2010 earthquake response
Collaboration between the Haitian government and NGOs after the 2010 earthquake contributed to a more accurate and complete master health facility list, which helped coordinate emergency response operations as well as strengthen the routine health information system. Open data and social networks facilitated the collection and sharing of health facility information and in maintenance of the list over time.
- Behavior Change Fast and Slow: Changing Multiple Key Behaviors a Long-Term Proposition?
An intensive radio campaign in rural areas of Burkina Faso addressed multiple key behaviors to reduce child mortality, using a randomized cluster design. After 20 months, despite innovative approaches and high reported listenership, only modest reported change in behavior was found, mainly related to care seeking rather than habitual behavior such as hand washing. Various methodologic difficulties may have obscured a true greater impact. Analysis of the intervention after its full 35-month duration may reveal more impact, including on actual child mortality. Improving a number of key behaviors is essential to child survival efforts, and much of it may require strong and sustained efforts.
