Rural general practice placements: alignment with the Australian Curriculum Framework for Junior Doctors.

OBJECTIVES: To review the available literature regarding skills and competencies gained by junior doctors in rural and regional general practice placements and their alignment with the Australian Curriculum Framework for Junior Doctors (ACFJD). STUDY DESIGN: A comprehensive literature review using a three-phase process. Articles were initially identified from database searches in OvidSP and Scopus. Additional information was obtained after a hand search of contents pages from relevant journals and from reports, conference abstracts and grey literature. Documented skills and procedures were mapped against the competencies from the ACFJD. DATA SOURCES: We analysed 36 relevant articles written in English and published during 1997-2011. Articles referring to learning outcomes for junior doctors training with rural general practitioners were included. DATA SYNTHESIS: Evidence was available of the advantages of junior doctor rural general practice placements in gaining advanced skills in the areas of communication and professionalism, as well as developing autonomy in clinical management and decision making. Less evidence was available regarding exposure to particular clinical conditions and development of specific clinical skills. CONCLUSION: Rural and regional general practice placements for junior doctors are likely to comply with the ACFJD requirements and, further, provide excellent learning opportunities in several domains of the curriculum. However, there was little research published confirming learning outcomes for junior doctors in rural general practice settings.

Effect of Frequency-Dependent Attenuation on Predicted Histotripsy Waveforms in Tissue-Mimicking Phantoms.

Tissue-mimicking phantoms are employed for the assessment of shocked histotripsy pulses in vitro. These broadband shock waves are critical for tissue ablation and are influenced by the frequency-dependent attenuation of the medium. The density, sound speed and attenuation spectra (2-25 MHz) were measured for phantoms that mimic key histotripsy targets. The influence of non-linear propagation relative to the attenuation was described in terms of Gol'dberg number. An expression was derived to estimate the bandwidth of shocked histotripsy pulses for power law-dependent attenuation. The expression is independent of the fundamental frequency of the histotripsy pulse for linear frequency-dependent attenuation.
