Field Test

The Arktek's practical performance has been well-proven in studies done by Aucma and Global Good in Senegal and Ethiopia. Deployed in a variety use cases and extreme environments, the device provided actual immunizations to children in populations served by the trial-site health posts. In addition to demonstrating reliable technical performance, the device received very positive responses from the health workers who used it daily. They highlighted its ease of use, time-saving benefits, excellent temperature stability and minimum maintenance is required. An Ethiopian clinician commented“Previously,vaccinating daily was unthinkable,but now the PVSD assists to vaccinate anytime as long as the children come and the monthly consumption of vaccine is at hand.”

Senegal

Arktek Passive Storage Device (PSD) was field tested in remote health posts and clinics in Senegal under a wide range of usage conditions. The primary purpose of this studies was to characterize and demonstrate Arktek PSD’s thermal and hold-time performance, in real-world settings, as well as to test the physical robustness of the device in harsh environments. This field test was conducted in collaboration with PATH and the Senegal Ministry of Health.

Field Test Details

Test Dates: December 2013 to June 2014
Locations: Northern Saint Louis; Central Kaolack
Use Cases: Central District Delivery of Loaded Device; Central District Delivery of Vaccines/Ice Pack; Health Post Collection of Loaded Device; Health Post Collection of Vaccines/Ice Packs
No. of Devices Tested: 16
Metrics Considered: Thermal and technical performance; Service metrics analysis of vaccine availability; Systems fit and supply chain viability; User experience and design feedback; Cost comparison versus existing solutions.

Key Results

Technical thermal performance met WHO temperature requirements of 0°C to 10°C without the need for an external power source.
Hold times of 35 days were successfully achieved for all use cases.
Device presented potential cost advantages in remote, off-grid settings.
Demonstrated fit with existing vaccine logistic systems.
Received positive user feedback.
Proved easy to use, effective, and reliable for use in routine storage of vaccines.

Ethiopia

Arktek PSD was field tested in remote Ethiopian health posts under a range of usage conditions. The primary purpose of these studies was to assess Arktek PSD’s overall performance under extreme conditions, as well as impact on workflow in cases in which Arktek PSD was introduced to health posts with no existing cold chain equipment. In addition, Arktek PSD was evaluated under a use case of extended, multi-week outreach to remote populations. These field tests were conducted in collaboration with UNICEF and Ethiopia’s Federal Ministry of Health.

Field Test Details

Test Dates: December 2013 to June 2014
Locations: The Southern Nations, Nationalities and Peoples’ Region (SNNPR); the Afar Region
Use Cases: 1、Routine Delivery;
2、Extended Outreach: Central Camp;
3、Extended Outreach: Mobile Team
No. of Devices Tested: 7
Metrics Considered: Thermal and technical performance under extreme conditions; Vaccine and ice logistics; Limited service metrics data; User experience feedback.

Key Results

Arktek PSD proved to be effective and reliable in providing stable, temperature control between 0°C to 10°C without the need for an external power source in all use cases and under a wide variety of conditions.
Where data was available, thermal hold times were consistent or exceeded hold time performance requirements of 35 days.
Received positive user feedback from health workers of all skill-levels.
Proved easy to use, effective, and reliable for use in vaccine storage under extreme conditions.
