Fig. 1: Illustrative example of the impact of a capacity ceiling of 5500 injections per month on the delivery of standard of care and on delivery of a new treatment which halves the required number of injections.

The orange shaded areas represent the potential cost savings associated with avoided injections that might be realised with a hypothetical new treatment while the blue shaded area represents the potential number of necessary injections that would go unadministered due to a capacity ceiling, which could in turn be extrapolated to a deficit in patient outcomes. Numbers underlying example based roughly on actual and forecasted number of injections in a UK tertiary hospital setting as presented in ref. [9].
