To the Editor: Walters and Dawson1 correctly highlight access block (hospital overcrowding) as a whole-of-system problem. Acute medical assessment and admission units (AMAAUs), or other similar incarnations in Australia and New Zealand, are part of the solution, although the evidence presented is low-level non-Australasian data. The reduced length of stay achieved by these units and reported in papers cited by Walters and Dawson would, if replicated in Australasia, produce additional capacity, improving bed availability and patient flow. As has been repeatedly stated: it’s all about available beds!2
