tefilla - Proper protocol for saying Mi Sheberach for the ill

I've seen different shuls do different methods of saying Mi Shebreach for the ill. Methods I have seen:

• Chazzan (or gabbai) says the intro aloud; people line up and give him the name and he says them aloud


• Same as above except that he reads off a printed list or a stack of cards / notes rather than people lining up. Those who are in the cong. who did not have their name submitted don't line up to announce the name, but say the name to themselves, silently.


• Chazzan says the intro then pauses. He will read names from the list silently and others who have not submitted names will say their names silently. Then, he concludes the end of the blessing aloud

I've also seen some cong. say separate prayers for males and females while others place them together. Does this matter? Is there a preferred method?

I am curious if there is any specific protocol mentioned in Shulchan Aruch or elsewhere. Or, is any method fine?
