Effectiveness of peer supervision on appropriate treatment of non-bloody diarrhoea
As seen in regression table 4 and visual inspection of Fig. 5, prior to introduction of the intervention (peer supervision), the proportion of appropriately treated children with non-bloody diarrhoea in the comparison district was 51.3%. This was followed by a 2% monthly increase (P = 0.099, CI = [-1.32, 5.44]) until October 2016.
In the first month of the intervention (November 2016), the proportion of appropriately treated children with non-bloody diarrhoea was 4% higher in the intervention (P = 0.448, CI = [-9.85, 17.19]) compared to the comparison district. However, this difference was not statistically significant. Consequently, there was a slight decrease in appropriate non-bloody diarrhoea treatment of 0.37% per month (P = 0.74, CI = [-3.74, 2.99]). The intervention significantly decreased the proportion of children appropriately treated for non-bloody diarrhoea by 4% during the intervention period (p <0.05, CI = [-7.95, -0.13]) compared to the comparison district. In addition, post intervention trend results revealed that introduction of the intervention decreased the proportion of appropriately treated children at a rate of 1% (p <0.06, CI = [-1.95, 0.02]).
