Ethics approval and consent to participate
: The Ethical Committee of the “Université de Bretagne Occidentale” (UBO), France approved the study for the whole of Europe: Decision N ° 6/5 of December 05, 2011. The Université de Bretagne Occidentale ethics committee provided ethical approval for recruitment of doctors from overseas because of the low-risk nature of the study, and the practical implications of obtaining ethics from multiple countries for the recruitment of small numbers of health professional participants using snowballing. Further, the participant recruitment strategy detailed above precluded us from pre-emptively knowing with certainty which countries we would recruit from and prospectively apply for ethical approval from each country.The participants provided their written informed consent to participate in the study.
