Unlocking hidden hospital beds: national medical ward flow measures to make inpatient delays visible.

Australia's hospital performance framework measures emergency department throughput and elective surgery waiting times, but ignores the inpatient journey where older Australian patients face invisible delays. This Perspective proposes National Medical Measures, simple ward-level flow indicators, to make delay patterns observable throughout the acute episode. The National Health Reform Agreement Addendum 2026-2031 requires Health Ministers to develop performance indicators for long-stay patients and cross-sector interfaces; this policy window should include ward-flow measurement. These measures would deliver national visibility of inpatient delays for the first time, establishing the baseline evidence needed to inform earlier clinical intervention, future target setting, and capacity planning.
