Home-based oral rehydration therapy in rural Zimbabwe

A study was carried out in four rural areas of Zimbabwe to assess the acceptability, feasibility and accuracy of sugar-salt solutions and to investigate the action taken during a recalled episode of diarrhoea in a child. Only 5% of respondents gave the child a sugar-salt solution at home during the described illness yet a majority (52%) claimed knowledge of oral rehydration techniques. A great variety of recipes were described; 46% of respondents knew a recipe for a solution containing sugar and salt and 12% were able to describe the standard recipe for sugar-salt solutions. Those who knew a recipe for a sugar-salt solution were asked to prepare a sample for chemical analysis; of those who prepared a sample, 26% prepared a solution having both sucrose and sodium concentrations within the safe and effective ranges. Surprisingly therefore, 12% (26% X 46%) of rural adults were able to prepare a safe and effective oral rehydration solution, despite the fact that there is as yet no concerted programme for the promotion of home-based oral rehydration therapy in Zimbabwe. The standard method of preparation was taught to all respondents who had no previous knowledge of sugar-salt solutions. Recall of the standard method was good; after a period of 11 to 26 days 64% of respondents remembered the correct recipe and 84% prepared a solution having both sucrose and sodium concentrations in the safe and effective ranges. 92% of all households had a teaspoon, sugar and salt and 88% had all the required items: a 750 ml bottle, a teaspoon, sugar and salt. It is concluded that home-based oral rehydration therapy using sugar-salt solutions is an acceptable and feasible strategy for the early management of acute diarrhoea in rural Zimbabwe.
