Whole-of-hospital response to admission access block: the need for a clinical revolution

To the Editor: Walters and Dawson1 highlight growing interest in new models of care aimed at ameliorating hospital-bed pressures and access block. They advocate acute medical assessment and admission units (AMAAUs) as a potential solution, and claim, principally based on the United Kingdom’s experience, that these units can significantly improve clinical care and patient outcomes. A recent systematic review confirms that these units (which have attracted several different synonyms) have promise, although controlled trials have yet to be performed, and publication bias remains a potential confounder.2
Experience with such units in Australia and New Zealand is growing, with more than 30 units in operation, and up to another 15 due to open over the next few years. Several national workshops conducted during the past 12 months have allowed staff of the units to share lessons and insights, and to debate how to balance service needs with resource availability. Operating standards for AMAAUs have been developed by the Internal Medicine Society of Australia and New Zealand (IMSANZ),3 which represents consultant general physicians. A recent survey shows the operations of Australasian units concord, in the most part, with these standards.4
We caution against Walters and Dawson’s suggested separation of AMAAU physicians into two streams — acute physicians working shifts, and ward-based general physicians responsible for patients requiring transfer from the AMAAU. Given that at least half of AMAAU patients will require transfer to inpatient wards, and many may warrant ongoing outpatient care even if discharged from the AMAAU, the need for continuity of care is paramount at the interface between the AMAAU and ward or clinic. To minimise the number of handovers and their attendant hazards and inefficiency, the medical team assessing and managing the patient in the AMAAU should ideally be the same team that provides ongoing inpatient (and indeed subsequent outpatient) care. This practice also eliminates any confusion around who is ultimately responsible for decisions about individual patient care, particularly for patients who remain in the AMAAU for any length of time. General physicians can acquire and maintain skills in acute medicine by making use of professional development programs sponsored by the IMSANZ. Clinical directors are needed in AMAAUs to oversee unit operations, develop policies and procedures, and provide capacity for rapid consultant response if on-call consultants are temporarily unavailable. The real challenge, to which Walters and Dawson refer, is the need for health care professionals to recognise that whole-of-hospital redesign solutions — which include AMAAUs — are needed, if access block in emergency departments is to be successfully overcome.
