Results: the generic CHW logic model
The generic CHW logic model (Figure 1) posits that optimal CHW performance (“Results”) is a function of high quality CHW programming (“Activities at the program level”), which is reinforced, sustained, and brought to scale by robust, high-performing health and community systems (“Activities at the system level”), both of which mobilize essential inputs and put in place processes needed to fully achieve the objectives of improved performance (“Inputs”). A range of contextual factors can also influence programming, system functioning, and performance. The component parts of the model are described briefly below, beginning with the intended results and working backward.
