I was involved in a slow code recently. (I won't say where, or when, or with whom.) They are slippery and repugnant. Rarely can any of the parties involved say with satisfaction or complete clarity when, or by whom, the slow code was suggested or agreed to. It is a substitute for an honest discussion of options with the patient and family, and it is a legal minefield.
Remind me not to get involved in them again ... when I have a choice in the matter.
