Logic model of program monitoring and evaluation.

<p>Inputs, outputs and outcomes of programmes are evaluated with increasingly rigorous data collection. Inputs refer to equipment, finances and time invested in order to achieve outputs, such as better trained surgeons or increased surgical output. The outputs result in processes, such as ongoing staff training. The outputs, if successful lead to outcomes that have a measureable impact, such as lower morbidity and mortality of surgical interventions in LMICs. Success of the program is evaluated over the short, medium and long term whereby short term indicators of success, such as the number of operations performed during a single visit, offer a weak indication of success; Long term indicators of success, such as a recorded decrease in morbidity associated with a particular surgical condition, offer a strong indicator of program success.
