Predictors of an increased in vitro thrombotic and bleeding tendency in critically ill trauma and non-trauma patients.
Trauma patients are at a high risk of both bleeding and thromboembolism. This study assessed whether conventional coagulation blood tests were reliable predictors of an increased in vitro thrombotic and bleeding tendency of trauma and non-trauma patients. Conventional coagulation blood tests and thromboelastographs of 63 trauma and 63 randomly selected, critically ill non-trauma patients were compared. ⋯ Prolonged International Normalized Ratio (>1.5) and activated Partial Thromboplastin Time (>40 seconds) were, however, not significantly associated with an increased in vitro thrombotic or bleeding tendency. In conclusion, in vitro thrombotic tendency was more common than bleeding tendency in critically ill trauma and non-trauma patients. Platelet counts and fibrinogen concentrations were better predictors of increased in vitro thrombotic and bleeding risks than International Normalized Ratio or activated Partial Thromboplastin Time.

ReviewDebriefing after simulation-based non-technical skill training in healthcare: a systematic review of effective practice.
Non-technical skills training in healthcare frequently uses high-fidelity simulation followed by a facilitated discussion known as debriefing. This type of training is mandatory for anaesthesia training in Australia and New Zealand. Debriefing by a skilled facilitator is thought to be essential for new learning through feedback and reflective processes. ⋯ There was no added performance improvement when review of a video recording was added to facilitator-led debriefing. One study reported no performance improvement after debriefing. Without empirical evidence that is specific to the healthcare domain, theories of learning from education and psychology should continue to inform practices and teaching for effective debriefing.

ReviewResearch without informed patient consent in incompetent patients.
Most patients needing intensive care cannot give informed consent to participation in research. This includes the most acutely and severely ill, with the highest mortality and morbidity where research has the greatest potential to improve patient outcomes. ⋯ Various models have been suggested for research without patient informed consent when intervention is urgent and cannot wait until first person consent is possible, including a waiver of consent if conditions are met. A nationally consistent model is proposed for Australia with a robust process for initial waiver of consent followed by first person consent to further research-related procedures or ongoing follow-up when this can be competently provided.
