There are excellent algorithms/books out there. If you are running a telephone triage, you need an algorithm and policy to which everyone adheres and is clear. If not, someone needs to develop one one ASAP.
One such book to consult for assistance is below. Meantime, maybe someone who does tele triage in an ED or "ask a nurse" line may have some more specifics to share. Or you could try calling the ED/Triage nurses in your area and asking them for examples/algorithms. Good luck.
