Managing the poultry red mite, Dermanyssusgallinae (De Geer) by conventional means (i.e., synthetic acaricides) has become increasingly problematic. As a possible alternative, research has identified several plant essential oils that are toxic to D. gallinae. However, essential oils are highly volatile and any acaricidal effect they exert could be(More)
AIMS To analyse recent published information about the Health and Disability Commissioner's investigations in the context of The New Zealand Medical Council's Domains of Competence and investigate possible relationships. METHODS Retrospective review of 100 recent Health and Disability Commissioner (HDC) investigations published online (all cases reviewed(More)
"First, do no harm" is a medical admonition; but harm does occur. There is thus mounting pressure for Medicine to adopt more rigorous systems to ensure professional competency. Traditionally, medical education and professional development has focussed on developing clinical expertise and technical skills within each speciality. Recent studies into the(More)
BACKGROUND An explanation is offered for the asymmetry of Receiver Operating Characteristic (ROC) curves obtained from pilots' decisions to eject. The curves can be fitted by a Gaussian model with unequal variances; however, that model does not provide a ready interpretation of the shape of the obtained ROCs. HYPOTHESIS In an emergency, a pilot receives(More)
BACKGROUND This study investigated a proposal of the Royal New Zealand Air Force to lower its designated ejection decision height (EDH) of 10,000 ft above ground level (agl) so that pilots had more time to make a correct and timely ejection decision. Hypothesis Lowering the EDH will result in pilots adhering to the prescribed height for ejection and enable(More)
BACKGROUND Although the technology of ejection-seat systems is highly developed and automated, the decision about whether to eject still rests with the pilot. One factor thought to affect that decision is the height at which the decision must be made. For this reason the Royal New Zealand Air Force considered lowering its designated ejection decision height(More)
This paper seeks to provide an overview for applying lessons learned in aviation safety investigation to safety investigation in the healthcare industry. There are well established regulations and procedures in aviation that make safety the end product of any accident investigation. Furthermore, standards of practice in aviation are well documented and are(More)
OBJECTIVE Little is known about which attributes the patients need when they wish to maximise their capability to partner safely in healthcare. We aimed to identify these attributes from the perspective of key opinion leaders. DESIGN Delphi study involving indirect group interaction through a structured two-round survey. SETTING International electronic(More)
Although the published work in health care increasingly promotes aviation as a high-reliability industry to be emulated, there is little empirical research to justify equating the dynamics of health care's operating environment with that of aviation. This article examines some of the potential key areas of difference between the two professional groups with(More)
