The supply of blood in many low- and middle-income nations in Sub-Saharan Africa (SSA) does not meet the patient care needs. Lack and delay of blood transfusion cause harm to patients and slow the rate of progress in other parts of the health system. Recognizing the power of implementation science, the BLOODSAFE Program was initiated which supports three SSA research study teams and one data coordinating center (DCC) with the goal to improve access to safe blood transfusion in SSA.The study team in Ghana is focusing on studying and decreasing iron deficiency in blood donors and evaluating social engagement of blood donors through different approaches. The study team in Kenya is building a "vein to vein" workflow model to elucidate and devise strategies to overcome barriers to blood donation and improve infrastructural components of blood product production and use. The Malawi team is studying the infectious disease ramifications of blood donation as well as blood donor retention strategies aimed at blood donors who commence their donation career in secondary schools.Together the project teams and the DCC work as a consortium to support each other through a shared study protocol that will study donor motivations, outcomes, and adverse events across all three countries. The BLOODSAFE Program has the potential to lead to generalizable improvement approaches for increasing access to safe blood in SSA as well as mentoring and building the research capacity and careers of many investigators.

There is a critical shortage of blood available for transfusion in many low- and middle-income countries. The consequences of this scarcity are dire, resulting in uncounted morbidity and mortality from trauma, obstetric hemorrhage, and pediatric anemias, among numerous other conditions. The process of collecting blood from a donor to administering it to a patient involves many facets from donor availability to blood processing to blood delivery. Each step faces particular challenges in low- and middle-income countries. Optimizing existing strategies and introducing new approaches will be imperative to ensure a safe and sufficient blood supply worldwide.

Background Supplemental oxygen is an essential treatment for childhood pneumonia but is often unavailable in low-resource settings or unreliable due to frequent and long-lasting power outages. We present a novel medium pressure reservoir (MPR) which delivers continuous oxygen to pediatric patients through power outages. Methods An observational case series pilot study assessing the capacity, efficacy and user appraisal of a novel MPR device for use in low-resource pediatric wards. We designed and tested a MPR in a controlled preclinical setting, established feasibility of the device in two rural Kenyan hospitals, and sought user feedback and satisfaction using a standardized questionnaire. Results Preclinical data showed that the MPR was capable of bridging power outages and delivering a continuous flow of oxygen to a simulated patient. The MPR was then deployed for clinical testing in nine pediatric patients at Ahero and Suba Hospitals. Power was unavailable for 2% of the total time observed due to 11 power outages (median 4.6 min, IQR 3.6–13.0 min) that occurred during treatment with the MPR. Oxygen flowrates remained constant across all 11 power outages. Feedback on the MPR was uniformly positive; all respondents indicated that the MPR was easy to use and provided clinically significant help to their patients. Conclusion We present a MPR oxygen delivery device that has the potential to mitigate power insecurity and improve the standard of care for hypoxemic pediatric patients in resource-limited settings.

Introduction Pneumonia is the leading cause of death globally in children. Supplemental oxygen reduces mortality but is not available in many low-resource settings. Inadequate power supply to drive oxygen concentrators is a major contributor to this failure. The objectives of our study were to (a) assess the availability of therapeutic oxygen; (b) evaluate the reliability of the electrical supply; and (c) investigate the effects of suboptimal oxygen delivery on patient outcomes in selected healthcare facilities in rural Kenya. Materials and methods A cross-sectional descriptive study on oxygen availability and descriptive case series of Kenyan children and youth hospitalized with hypoxemia. Results Two of 11 facilities had no oxygen equipment and nine facilities had at least one concentrator or cylinder. Facilities had a median of seven power interruptions per week (range: 2-147). The median duration of the power outage was 17 minutes and the longest was more than 6 days. The median proportion of time without power was out 7% (range: 1%-58%). Fifty-seven patients hospitalized with hypoxemia (median oxygen saturation 85% [interquartile range {IQR}: 82-87]) were included in our case series. Patients received supplemental oxygen for a median duration of 4.6 hours (IQR: 3.0-7.8). Eighteen patients (32%) faced an oxygen interruption of the median duration of 11 minutes (IQR: 9-20). A back-up cylinder was used in 5/18 (28%) cases. The case fatality rate was 11/57 (19%). Conclusion Mortality due to hypoxemia remains unacceptably high in low-resource healthcare facilities and may be associated with oxygen insecurity, related to lack of equipment and/or reliable power.

Background: Continuous positive airway pressure (CPAP) is a relatively low-cost technology which can improve outcome in neonatal and paediatric patients with respiratory distress. Prior work in a lower middle-income country demonstrated degradation of CPAP skills and knowledge after the initial training. Aims: To determine if a training-of-trainers (ToT) curriculum can decrease gaps in skills and knowledge between first-generation (trained by a United States physician and nurse) and second-generation healthcare providers (trained by local trainers) in Kenya, and to describe the usage pattern, outcome and safety in patients who received CPAP following the trainings. Methods: The first day of training entailed didactic and simulation sessions. On the second day participants were taught how to train others to use CPAP. First- and second-generation healthcare providers were tested on their skills and knowledge. Unpaired t-tests were used to test for equivalence. Prospective data on CPAP usage was collected following the initial trainings. Results: 37 first-generation healthcare providers (16 nurses; 21 physicians, medical/clinical officers) were trained as trainers and 40 second-generation healthcare providers (19 nurses, 21 physicians, medical/clinical officers) trained by first-generation healthcare providers were available for skills and knowledge testing. There were no statistically significant differences between first- and second-generation healthcare providers’ skills (90%, 95% CI 87–93 vs 89%, 95% CI 86–92) or knowledge scores (91%, 95% CI 88–93 vs 90%, 95% CI 88–93). A total of 1111 patients were placed on CPAP mostly by nurses (61%), prematurity/acute respiratory distress syndrome was the most common indication, nasal injury/bleeding (2%) was the most common reported adverse event, and the overall mortality rate was 24%. Conclusion: The ToT model was successful, nurses initiated CPAP most commonly, prematurity with acute respiratory distress syndrome was the most common indication, and adverse events were uncommon.

The Millennium Villages Project (MVP), based at The Earth Institute at Columbia University, is a bottom-up, community led approach to show how villages in developing countries can get out of the poverty trap that afflicts more than a billion people worldwide. With well-targeted, practical inputs can help the community invest in a path leading to self-sustaining development. There are 80 Millennium Villages clustered in 10 countries throughout sub-Saharan Africa. MVP is an important development process for empowering communities to invest in a package of integrated interventions aiming to increase food production, improve access to safe water, health care, education and infrastructure. The process benefits from synergies of the integrated approach and relies on community leadership as empowered by proven technological inputs. MVP is committed to a science-based approach to assess and monitor the progress of the communities towards clear objectives; the Millennium Development Goals (MDGs) and to do so with mechanisms that are scalable and sustainable. This approach offers much more than simply collecting and analyzing data since the mechanism used for recording progress would provide a bridge over the divide which separates the haves and the have-nots (by facilitating the sharing of solutions from one community to another bidirectionally). By so doing, it allows people to enhance their own futures in a sustainable manner. Solutions found in one community are transferable to similar communities in other MVP villages. To achieve this goal, the MVP requires an information and communication system which can provide both necessary infrastructure for monitoring and evaluation, and tools for communicating among the villages, cities and countries. This system is called the Millennium Global Village-Net (MGV-Net). It takes advantage of the latest in open source software (OpenMRS), databases (MySQL), interface terminology, a centralized concept dictionary, and uses appropriate technology locally for data entry.
