Fingers or spoons to make oral rehydration solution?

The accuracy and variability of the composition of oral rehydration solution (ORS) prepared by village health workers using (i) a finger measurement technique and (ii) a special ORS measuring spoon were compared. The sodium and sucrose concentrations were measured in 130 ORSs prepared by each technique. All the spoon-measured ORSs had acceptable levels of sodium and sucrose, compared with 93% of the finger-measured ORSs.
