Certainly we need to use "best practices" from a medical standpoint; but this must be done with sensitivity and an honest respect for religious and cultural considerations, along with the need people have to grieve.
Gross disregard for the wisdom, and for the religious and cultural sensitivities of others, will not get us where we want to go.

We must consider the whole person with respect, not just medical necessity. It's a balance that must be achieved.

And of course, missionaries also must respect the cultural and religious sensitivities of the people they seek to serve.
