The case for measuring functionality in a diarrhoea treatment kit

Measuring water using the flexi-pack

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:

  1. 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.
  2. 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.
  3. 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.

The following publications, drawn from the ColaLife (COTZ) Trial and more recent publications, underpin the case for more accurate measuring and the concept of using packaging as a measure.
