Developing international evidence suggests that cultural norms and ethical principles of a family, population or healthcare environment influence attitudes towards CAH, particularly where CAH has symbolic meaning; representing care, hope and trust. However, there is surprisingly little robust evidence regarding dying patients, or the wider general public's views, on the perceived value of CAH in the last days and hours of life. Accordingly, a need for greater understanding of the perceptions regarding CAH, and their effects, is required.
