Annual Report

The growth of our programs in 2015 laid the groundwork for the milestones in our 2016 Annual Report.

STOVETRACE REPORT: CLIMATE AND HEALTH METRICS

Transparent Climate and Health Metrics: An Open Data Dashboard and Wireless Platform for Cookstove Monitoring
Nexleaf and the World Bank collaborated on a project to monitor and evaluate cookstove use and subsequent PM2.5 reductions, to support sensor-enabled climate financing.  With support from Berkeley Air Monitoring Group and The Energy and Resources Institute, and in consultation with Scripps Institution of Oceanography, Nexleaf completed the first phase of a three phase project.
StoveTrace sensors were deployed in 79 households in four states in India, yielding unprecedented insight into user preference and behavior and spurring tremendous technological development of the platform. The investigation revealed that  the health benefits of cleaner air are less immediate and tangible, and do not hold much sway over women’s preference. In 10 additional households, prototypes of integrated PM2.5devices were deployed, but further technological development and field testing are required to draw conclusions based on air quality data.
This work aims to scale an integrated sensor and increase the capacity of the open data platform accordingly.

COLDTRACE REPORT: RANDOMIZED CONTROL TRIAL

RTM Increases Uptime and Decreases Freezing Duration in Vaccine Refrigerators: A Randomized Control Trial Analysis
The randomized control trial conducted by Nexleaf with the Mozambique Ministry of Health, VillageReach, PATH, and UNICEF evaluated the “uptimes” of vaccine refrigerators in rural communities. Health facilities using Nexleaf’s remote temperature monitoring (RTM) were evaluated in a controlled trial against facilities using 30 day temperature recorders (30DTR) and facilities using paper charts.
The study was conducted to learn: Do refrigerators with RTM devices capable of sending SMS alerts maintain higher uptimes than refrigerators monitored with 30DTRs or paper charts?
Health facilities were randomly selected and placed into three groups:
• Group 1 consisted of 29 health facilities with RTM + SMS alerts; staff received training on responding to RTM alerts, and Standard Operating Procedures (SOPs) were posted in clinics.
• Group 2 consisted of 28 health facilities monitoring fridges with 30DTR devices; staff received additional training on 30DTR usage.
• Group 3 consisted of 26 health facilities monitoring fridges with stem thermometers; staff recorded temperatures twice daily on paper charts.
Following a ten-month evaluation period, we found that vaccine refrigerators equipped with RTM capable of sending SMS alerts, monitored by trained health care professionals, achieved the highest amount of uptime (90%) and lowest percent of total time spent in WHO freeze alarm state (0.55%). However, Group 2, refrigerators monitored by 30DTR, experienced an average of three hours less in WHO heat alarm state than those with RTM.
