The case for incorporating measuring functionality into the design of the packaging of co-packaged ORS and Zinc for the treatment of diarrhoea can be summarised as follows:
- The ColaLife Operational Trial in Zambia (COTZ) found that when caregivers were given 1 litre sachets of ORS, only 60% mixed the ORS correctly. 40% either used too little or too much water.
- On the other hand when caregivers were given a Kit Yamoyo which enabled them to use the packaging to measure the correct amount of water, 93% mixed the ORS correctly.
- Caregivers who prepared ORS correctly were 2.36 times more likely to perceive it as an effective treatment compared to caregivers that did not prepare the solution to the correct concentration.
