- 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.
- Family Planning Supply Environment in Kinshasa, DRC: Survey Findings and Their Value in Advancing Family Planning Programming
A series of facility-based surveys that mapped all sites providing family planning services and that assessed readiness to provide services, using mobile phones, was feasible in a low-resource setting, contributing to mobilization of partners and increased donor support. Between 2012 and 2013, readiness to provide services increased from 44% of sites to 63%. Three factors most associated with productivity: type of facility (clinics more than hospitals or health centers), more years in operation, and number of methods available.
- Reducing Motor Vehicle-Related Injuries at an Arizona Indian Reservation: Ten Years of Application of Evidence-Based Strategies
Motor vehicle crashes decreased and seat belt use, including car seat use, increased in an American Indian and Alaska Native community through a multidisciplinary approach using strong partnerships among public health and law enforcement agencies; community outreach; mass media campaigns; and enactment and high-visibility enforcement of key laws, such as lowering the legal blood alcohol concentration limit for drivers and mandating use of occupant restraints.
- Introduction of Mobile Health Tools to Support Ebola Surveillance and Contact Tracing in Guinea
An informatics system consisting of a mobile health application and business intelligence software was used for collecting and analyzing Ebola contact tracing data. This system offered potential to improve data access and quality to support evidence-based decision making for the Ebola response in Guinea. Implementation challenges included software limitations, technical literacy of users, coordination among partners, government capacity for data utilization, and data privacy concerns.
- Regulatory Monitoring of Fortified Foods: Identifying Barriers and Good Practices
Food fortification with micronutrients often is not compliant with relevant standards, in large part because poor regulatory monitoring does not sufficiently identify and hold producers accountable for underfortified products. We propose these reinforcing approaches: clear legislation, government leadership, strong enforcement of regulations, improved financial and human capacity at the regulatory agency and industry levels, civil society engagement, simplified monitoring processes, and relationship building between industry and government.
- Prevalence and Incidence of Traumatic Experiences Among Orphans in Institutional and Family-Based Settings in 5 Low- and Middle-Income Countries: A Longitudinal Study
Contrary to some conventional wisdom, in this large study that randomly sampled orphans and separated children from 5 countries, prevalence of reported traumatic events was no worse among those institutionalized than among those in family-based care. Reported incidence of physical or sexual abuse was actually higher for those in family-based care. Understanding the specific context, and elements contributing to potential harm and benefits in both family-based and institutional care, are essential to promoting the best interest of the child.
- Estimating Contraceptive Prevalence Using Logistics Data for Short-Acting Methods: Analysis Across 30 Countries
Three models showed strong correlation between public-sector logistics data for injectables, oral contraceptives, and condoms and their prevalence rates, demonstrating that current logistics data can provide useful prevalence estimates when timely survey data are unavailable.
- The Astronomy of Africa’s Health Systems Literature During the MDG Era: Where Are the Systems Clusters?
The volume of literature on health systems in sub-Saharan Africa has been expanding since the 2000 MDG era. Focus has remained generally on categorical health themes rather than systems concepts. Topics such as scaling-up, organizational development, data use for decision making, logistics, and financial planning remain underrepresented. And quite surprisingly, implementation science remains something of a “black hole.” But bibliometric evidence suggests there is a shift in focus that may soon address these gaps.
- Women’s Groups to Improve Maternal and Child Health Outcomes: Different Evidence Paradigms Toward Impact at Scale
The Care Group model, with relatively intensive international NGO implementation at moderate scale, appears successful in a wide variety of settings, as assessed by high-quality evaluation with rich program learning. Another women’s group approach—Participatory Women’s Groups—has also been implemented across various settings but at smaller scale and assessed using rigorous RCT methodology under controlled—but less naturalistic—conditions with generally, although not uniformly, positive results. Neither approach, as implemented to date, is directly applicable to large-scale integration into current public programs. Our challenge is to distill the elements of success across these approaches that empower women with knowledge, motivation, and increased self-efficacy—and to apply them in real-world programs at scale.
- Remote Sensing of Vital Signs: A Wearable, Wireless “Band-Aid” Sensor With Personalized Analytics for Improved Ebola Patient Care and Worker Safety
This wireless sensor technology, currently being field-tested in an Ebola Treatment Unit in Sierra Leone, monitors multiple vital signs continuously and remotely. When connected with enhanced analytics software, it can discern changes in patients’ status much more quickly and intelligently than conventional periodic monitoring, thus saving critical health care worker time and reducing exposure to pathogens.
