Rapid response systems (RRS) in hospitals in Australia and New Zealand (ANZ) have been present for more than 20 years but governance of the efferent limb-the rapid response team (RRT)-has not been previously reported in detail. The objectives of this study were to describe current governance arrangements for RRTs within ANZ and contrast those against expected implementation, using the Australian Commission for Safety and Quality in Health Care National Standard 9 (S9) as a benchmark. Assessment focused on S9 subclauses 9.1.1 (governance and oversight), 9.1.2 (RRT implementation), 9.2.3 (data collection and dissemination), 9.2.4 (quality improvement), 9.5.2 (call reviews), 9.6.1 and 9.6.2 (basic and advanced life support [ALS] skill set). ⋯ However, there was a notable lack of consistency, especially around specialist involvement and audit processes. Although some findings from this study are reassuring, there is still potential for improvement. Further development of guidelines and the establishment of a regional RRS database may assist with achieving this.

Comparative StudyThe effects of haemodilution with succinylated gelatin solution on coagulation in vitro as assessed by thromboelastometry and impedance (multiple electrode) aggregometry.
We investigated the in vitro viscoelastic changes of progressive haemodilution with succinylated gelatin (SG) solution compared with normal saline (NS) using rotational thromboelastometry (ROTEM®). Whole blood (WB) samples obtained from 20 healthy volunteers were diluted in vitro with SG solution or NS by 10%, 20% and 40%. Fibrinogen concentration and ROTEM (EXTEM, FIBTEM) variables including coagulation time (CT), clot formation time (CFT), α-angle, and maximum clot firmness (MCF) were measured in the undiluted sample and at each degree of haemodilution. ⋯ We found that haemodilution of more than 20% with SG impaired coagulation greater than that observed with NS haemodilution in this in vitro study. This suggests that at 40% haemodilution with SG, a clinical scenario that could occur during resuscitation of a patient in grade IV haemorrhagic shock, impaired coagulation could occur. Frequent monitoring of coagulation is advised when SG solutions are administered rapidly during volume resuscitation.
