Deviation from accepted drug administration guidelines during anaesthesia in twenty highly realistic simulated cases.
Deviations from accepted practice guidelines and protocols are poorly understood, yet some deviations are likely to be deliberate and carry potential for patient harm. Anaesthetic teams practice in a complex work environment and anaesthetists are unusual in that they both prescribe and administer the drugs they use, allowing scope for idiosyncratic practise. We aimed to better understand the intentions underlying deviation from accepted guidelines during drug administration in simulated cases. ⋯ Underlying reasons for deviations included a strong sense of clinical autonomy, poor clinical relevance and a lack of evidence for guidelines, ingrained habits learnt in early training, and the influence of peers. Guidelines are important in clinical practice, yet self-identified deviation from accepted guidelines was common in our results, and all but one of these events was judged to carry potential for patient harm. A better understanding of the reasons underlying deviation from accepted guidelines is essential to the design of more effective guidelines and to achieving compliance.

Characteristics and expectations of fluid bolus therapy: a bi-national survey of acute care physicians.
There is little consensus on the definition or optimal constituents of fluid bolus therapy (FBT), and there is uncertainty regarding its physiological effects. The aims of this study were to determine clinician-reported definitions of FBT and to explore the physiological responses clinicians expect from such FBT. In June and October 2014, intensive care and emergency physicians in Australia and New Zealand were asked to participate in an electronic questionnaire of the reported practice and expectations of FBT. ⋯ Substantial variation was demonstrated in the magnitude of expected response within both specialties for each variable. Major variations exist in self-reported FBT practice, both within and between acute specialties, and wide variation can be demonstrated in the expected physiological responses to FBT. International explorations of practice and prospective quantification of the actual physiological response to FBT are warranted.

The incidence of ocular candidiasis and evaluation of routine opthalmic examination in critically ill patients with candidaemia.
Despite a paucity of data regarding both the incidence of ocular candidiasis and the utility of ophthalmic examination in critically ill patients, routine ophthalmic examination is recommended for critically ill patients with candidaemia. The objectives were to estimate the incidence of ocular candidiasis and evaluate whether ophthalmic examination influenced subsequent management of these patients. We conducted a ten-year retrospective observational study. ⋯ During examination, signs of ocular candidiasis were only present in one (2.9%) patient, who had a risk factor for ocular candidiasis. Based on these findings, the duration of antifungal treatment for this patient was increased. Ocular candidiasis occurs rarely in critically ill patients with candidaemia, but because treatment regimens may be altered when diagnosed, routine ophthalmic examination is still indicated.

Teaching and learning in undergraduate anaesthesia: a quantitative and qualitative analysis of practice at the University of Auckland.
Anaesthesia encompasses a broad range of knowledge and skills of relevance to graduating doctors. For the majority of new doctors, an undergraduate clinical rotation is their only exposure to anaesthesia practice. However, the content and approach to undergraduate anaesthesia education varies between institutions. ⋯ Our study found much unanticipated variability in student exposure, teaching practice and attitudes to teaching various skills or procedures between anaesthetists, and student opinion of their clinical attachment. The findings resulted in a review of many aspects of the attachment. It is likely that other institutions will have similar variability and we recommend they undertake similar exercises to optimise teaching and learning opportunities for undergraduate anaesthesia.

Overcoming barriers to the mobilisation of patients in an intensive care unit.
We conducted a quality improvement project aimed at increasing the frequency of mobilisation in our ICU. We designed a four-part quality improvement project comprising: an audit documenting the baseline frequency of mobilisation; a staff survey evaluating perceptions of the barriers to mobilisation; identification of barriers that were amenable to change and implementation of strategies to address these; and a follow-up audit to determine their effectiveness. The setting was a tertiary care, urban, public hospital ICU in South Australia. ⋯ Multivariable analyses showed that three out of four mobility outcomes did not significantly change between the baseline and follow-up audits, with a significant difference in favour of the baseline audit found for the fourth mobility outcome (maximum level of mobility). We concluded that implementing relatively simple measures to improve staff education, interdisciplinary communication and leadership regarding early progressive mobilisation was ineffective at improving mobility outcomes for patients in a large tertiary-level Australian ICU. Other strategies, such as changing sedation practices and/or increasing staffing, may be required to improve mobility outcomes of these patients.
