Costs in German hospitals move faster than reimbursement. Wage settlements in nursing and medical services feed straight into staff cost, while energy, medical supplies and materials follow general price development. Reimbursement, by contrast, is bound to mechanisms that reflect this movement only with a lag and only in part.
The result is not a one-off gap but a widening one. It cannot be closed by case volume growth, because the capacity required fails on staff availability — nor by pure material cost programs, whose leverage is limited relative to the staff cost block.
For management this means: a hospital deficit of this kind is a structural problem, not an efficiency problem. Efficiency programs buy time. They do not replace the structural decision.
