From insights to solutions
After months of discovery-design-iteration cycles, we formulated product design criteria that would serve to inform the development of the infection diagnostic. Criteria included specifics about who should deliver the diagnostic and how it should be administered, given the location of use. For example, if formal providers have the opportunity to provide care, the diagnostic should provide on-the-spot diagnosis to help patients avoid additional trips and also be bundled with the frequently used “maama kits” women are familiar with. If the diagnostic is used at home with an informal provider, the diagnostic must provide authoritative evidence to seek further treatment, be administrable by patients themselves, and not be invasive.
We also explored several design concepts that met these design criteria. One concept is a fever patch that women would wear immediately after labor. The patch can detect a continuous fever over a 25-hour period, which is a signal of infection at such a vulnerable time. As women experience intermittent fevers during labor, the seriousness of a continuous fever is commonly ignored. The fever patch is a non-invasive measure that shows when the wearer has a fever by filling with a red pattern that spreads over the patch. It gives an authoritative, yet unambiguous signal to women and their untrained caregivers that immediate help should be sought.
We also explored two kinds of kits, the first is a pregnancy care kit, assembled at the manufacturer, that includes diagnostics for all points of care: during the first antenatal care visit, the follow-up, and the post-natal care visit. The kit can be customized based on regional factors. For example, an HIV diagnostic would be included in Uganda, but not Bangladesh. The kit also could give providers guidance for how to administer diagnostics, and also, as patients could see which diagnostics they should be receiving, they could hold providers accountable to administer them.
The second kit is a diagnostic kit (pictured below) that would be assembled by a provider within a clinic. We found challenges in trying to keep current records, so the diagnostic kit helps keep patient information and test results together. The kit also incorporates the current method of test distribution and procurement that occurs in clinical settings, and can be customized based on what is in stock at the clinic.
