Primary Outcomes (end points)
We are running a 'Poker Trial' in which arms compete directly with the control on a set of paired intervention areas. The 'hands' are valued as follows:
Infestation: If an inspector uncovers an infested household. Base points = 500 with an additional 50 points for each additional infested house discovered
Risk & Coverage: If the average risk of searched households >=4 (of a 5-point scale) and the spatial coverage is less than or equal to 5% of the total number of households. Base points = 300 additional points: 5 per reduction of 1 house in the largest triangle, 1,2,3,4,5 for visits to houses in risk quintiles 1-5 respectively.
Risk alone: Mean risk of households visited >=4, but spatial coverage is not less than 5% of the total number of houses. Base points= 100, additional points 1,2,3,4,5 for each risk level.
Spatial coverage alone: Largest delauney triangle is <5% of total number of houses. Base points = 100, 5 additional for each reduction in size of the largest triangle.
