March’s arrival has brought a much-needed return to many of the essential services in northern Mozambique that the public health system and communities alike depend on. In early January we reported on the devastating loss of both electricity and transport due to severe flooding throughout the region, including many of the communities we work with in neighboring Malawi.Read full story

As a Technical Officer with VillageReach, I am responsible for working with our partners at the provincial health department and in the health centers to support new cold chain monitoring technology. In this role, and in my experience visiting rural health centers, I see firsthand the many challenges that exist in infrastructure, issues that greatly impact the cold chain and viability of vaccines. Energy in our communities is unreliable, so often times the refrigerators that store vaccines and other medical commodities lose power for hours or even weeks at a time. Health workers struggle to balance the time needed to adequately treat patients with their other administrative duties, and fixing a broken refrigerator is not part of their training. As all of these situations effect the viability of vaccines, they also affect the children who need them. A better cold chain can save lives. That is why I am excited about the opportunity to observe a simple new technology solution that I think could have great impact in solving these challenges.
While technology has become more and more common in addressing issues of health care in low resource communities, the most effective solutions are usually the most accessible and inexpensive, and ColdTrace is an example of such a technology. ColdTrace is a low cost solution that leverages the power, coverage and availability of mobile telecommunications services in remote/hard to reach areas to improve response time to problems in the Cold Chain Storage System. ColdTrace is a low-cost cellular phone which has a sensor added to it that can read and monitor temperature. VillageReach is working with Nexleaf to deploy and test ColdTrace devices in 90 health centers in Mozambique starting in May 2014.
How it works:
The phone with the built-in temperature sensor is installed in a central position of the fridge that holds the vaccines. The phone records the temperature at pre-configured intervals. When temperatures go out of the stipulated range, i.e. 2°C – 8°C for a pre-defined period, text messages are sent from the ColdTrace device to clinic staff. If the problem is not resolved within a certain period, escalated messages are sent to the District EPI (Extended Programme on Immunizations) Officer. If the problem is still not resolved, another escalated SMS is sent to the Provincial EPI Officer. Because this communication all happens so quickly, the time it takes to actually fix the equipment and get it back to operational is much faster than it would typically be. The SMS sets in motion a communication that is continually managed and repeated in the daily status messages until the problem is resolved. All the data is gathered and processed by ColdTrace and is uploaded to a central server and summaries of these data are sent on a monthly basis to the Ministry of Health.
What are the benefits of ColdTrace to immunization programs?
Through this initial deployment, we aim to show that ColdTrace:
- Gives time back to health clinic staff enabling them to focus on their primary job of caring for patients instead of maintenance issues.
- Decreases the time it takes to identify a problem and coordinate the resources to fix it due to an immediate and ongoing communication that initiates with ColdTrace.
- Provides the Ministry of Health in Mozambique with critical data needed to evaluate the performance of various clinic response times, as well as different models of refrigerators, helping to improve informed decision-making.
I look forward to seeing the results of ColdTrace in Gaza Province so that VillageReach can share what we have learned about this new technology along with our partner, Nexleaf, and help bring a cost-effective, sustainable solution to more communities in need of cold chain support.
