Collecting high quality data to effectively measure quality of care and productivity

We need to measure quality of care and productivity effectively, so it is possible to demonstrate improvements in the system. For example, how do we know this way of doing it is better? This will need to include quality standards (what is ‘good’), how they are measured, and how to demonstrate the value of the workforce. We will need to ensure that data is of a high quality and that it is valid and reliable.
