ReviewRapid response teams in adult hospitals: time for another look?
Rapid response teams (RRT), alternatively termed medical emergency teams, have become part of the clinical landscape in the majority of adult hospitals throughout Australia and New Zealand. These teams aim to bring critical care expertise to the bedside of clinically deteriorating patients residing in general hospital wards with the aim of preventing adverse outcomes, in particular death or cardiorespiratory arrests. ⋯ Adverse unintended consequences of RRT systems and the opportunity costs involved in maintaining such systems have not been subject to study, amid concerns RRT may be compensating for other potentially remediable system of care failures. This article presents an overview of the current state of play of RRT in hospital practice as they pertain to the care of adult patients and identifies several issues around their implementation and evaluation that should be subject to further research.

Treatment for the majority of patients with myelofibrosis is primarily based on symptom control as curative allogeneic stem cell transplantation is typically offered only to younger patients, especially those with poor prognosis disease. Around 50% of patients with myelofibrosis have the JAK2(V617F) mutation, but almost all patients have aberrant activation of the JAK-STAT signalling pathway. Recent efforts have focussed on the clinical use of JAK2 inhibitors to treat myelofibrosis. ⋯ Consistent with the physiological role of JAK signalling the major toxicity of ruxolitinib is cytopenia. Managing cytopenia is key to maximising the therapeutic benefit of ruxolitinib. Further research into the safety of ruxolitinib in patients with thrombocytopenia is warranted, as is its role in special subgroups of patients, such as those undergoing stem cell transplantation and those experiencing thrombosis as a major manifestation of myelofibrosis.
