The paper describes the performance measurement system of the maternity pathway used in Tuscany by health care professionals, general managers and regional policy-makers. This system uses 19 indicators grouped in six dimensions: population's state of health; compliance with regional guidelines; efficiency and financial performance; clinical and health assessment; patient satisfaction; and employees' satisfaction. The results are represented on a spider diagram that summarizes the results on the different dimensions. The Tuscan performance measurement system of the maternity pathway has been used to identify best practice within, and their adoption throughout, the Tuscan public health care system.
