Productivity relates the outputs of a service to the inputs:
Productivity = Outputs of a service/Inputs
Where inputs are defined as the resources used, such as the number of hospital beds, to produce an output, such as the number of patients admitted per bed per year.
Examples of productivity measures:
- Episodes of care/Cost
- Number of episodes of care/Number of beds

Example of the term in use:
… the main interest is on how output changes over time, using annual measures. It is then possible to assess change in productivity by dividing the time series for outputs by the time series for the volume of inputs – that is, spending deflated to adjust for changes such as NHS pay and price rises.
