In recent years in Italy, as in other European countries, profound changes have been introduced in health care both at central and regional levels. Most of them were oriented towards a shift from 'hospital-centred' health care to health care based more on primary care services. This transition pursues two objectives: giving more effective responses to citizens' needs and reducing public health expenditure. Changes that involve organizational structure must also be carried out with the introduction of measurement tools that can help in planning and can control the changes. The paper provides the results obtained through the experience of modelling a measurement system for primary care carried out in 2004 and 2005 by some territorial managers and controllers in the Tuscan Health system, and the main issues in measuring primary care services emerging from this pilot experience focused on integrated home care services.
