Australian radiographer roles in the emergency department; evidence of regulatory compliance to improve patient safety - A narrative review.

OBJECTIVES: Using a narrative approach, this paper aims to determine the extent of Australian radiographers' regulatory compliance to improve patient safety when performing appendicular X-ray and non-contrast brain computed tomography (CT) in the Emergency Department (ED). KEY FINDINGS: A narrative review explored relevant literature and key regulatory policy. Ten documents were identified, three main themes were developed related to the radiographer roles in X-ray request justification, dose optimisation and preliminary image evaluation (PIE). Radiographers were equally aware of justification and optimisation pre and post the introduction of a Medical Code of Practice. The collective PIE accuracy of radiographers remained unaffected by changes in mode of PIE delivery and regulatory factors but varied based on the anatomical region. CONCLUSION: While current Australian regulations mandate radiographer request justification, dose optimisation and PIE, the degree of compliance by Australian radiographers remains uncertain. Current literature provides evidence that radiographers can improve patient care and safety through justification, optimisation, and PIE delivery. Change in workplace practice, supported by key stakeholders including radiologists, is essential to integrate radiographers' functions into routine ED clinical practice. Further research is required to audit radiographers' regulatory compliance to improve patient safety. IMPLICATIONS FOR PRACTICE: Patient safety in ED can be improved with timely and accurate diagnosis provided by radiographers. Radiographers have a professional obligation to adhere to the capabilities and standards for safe medical radiation practice defined by Australian regulations. Therefore, radiographers must justify the X-ray request, optimise the radiation dose where appropriate and communicate urgent or unexpected findings to the referrer.

Health-related messages in consumer magazine advertising.

OBJECTIVE: To characterize the patterns of health-related messages in consumer advertising from U.S. magazines. DESIGN: Observational survey of advertisements occupying a third of a page or more from the January 1994 issues of the 11 most popular consumer magazines. MEASUREMENTS AND MAIN RESULTS: Health messages were present in 22.8% (85/372) of all the advertisements reviewed. Of the advertisement categories (prescription medication, over-the-counter medication, exercise-related product, health service, health device, diet/health-related food, and other), over-the-counter medications were the most common among the advertisements that had health messages (32.9%, 28/85) (7.5% of the total advertisements, 28/372). The five advertisements for prescription medications were duplications of two different advertisements, one for a hair promotion product and one for hormone replacement therapy. Products related to diet and exercise together represented 29.4% (25/85) of all advertisements with health messages. Three advertisements (3.5%) were for health devices, and five (5.9%) were for health services. CONCLUSIONS: Health-related messages are frequent in consumer advertising. The effects of health marketing on consumer protection, health care costs, and the physician-patient relationship are discussed.

Two-dimensional imaging of soot volume fraction by the use of laser-induced incandescence.

A recently developed laser-induced incandescence technique is used to make novel planar measurements of soot volume fraction within turbulent diffusion flames and droplet flames. The two-dimensional imaging technique is developed and assessed by systematic experiments in a coannular laminar diffusion flame, in which the soot characteristics have been well established. With a single point calibration procedure, agreement to within 10% was found between the values of soot volume fraction measured by this technique and those determined by conventional laser scattering-extinction methods in the flame. As a demonstration of the wide range of applicability of the technique, soot volume fraction images are also obtained from both turbulent ethene diffusion flames and from a freely falling droplet flame that burns the mixture of 75% benzene and 25% methanol. For the turbulent diffusion flames, approximately an 80% reduction in soot volume fraction was found when the Reynolds number of the fuel jet increased from 4000 to 8000. In the droplet flame case, the distribution of soot field was found to be similar to that observed in coannular laminar diffusion flames.
