Impact of educational intervention on knowledge of mothers regarding home management of diarrhoea.

A pre and post comparison study was carried out in the field practice area of M.S. Ramaiah Medical College Bangalore, Karnataka to assess the impact of educational intervention on the knowledge of mothers of under five children on home management of diarrhoeal diseases. Sample of 225 mothers were included in the study. The study was conducted in 3 stages. Stage I--initial knowledge, attitude and practice of mothers was assessed. Stage II--one to one educational intervention was conducted and supported by audiovisual aids and live demonstration. Stage III--included post intervention knowledge, attitude and practice after 2 months and 2 years. After the educational intervention, there was significant improvement on knowledge of mothers regarding definition of diarrhoea (P < 0.001), signs of dehydration (P < 0.001), awareness of ORS solution (P < 0.001), correct preparation of ORS solution (P < 0.001), shelf-life of ORS solution (P < 0.001), seeking health care (P < 0.001) and rational drug therapy during diarrhoea (P < 0.001). McNemar test was used to find out the change in knowledge before and after the educational intervention. The overall knowledge scores improved significantly after 2 months (P < 0.001) as well as 2 years (P < 0.001) of the educational intervention. Though the proportion of mothers retaining the knowledge at the end of 2 years dropped, yet there was significant improvement (P < 0.001) when compared to the baseline study.
