Easier to write. We spend 5 minutes talking about you at handoff (and I need to write down everything AS the other person is talking) then I have to write a mini essay about each person. Abbreviations are highly specific to specialty, but much easier. An example from my specialty might be:

BIBA GSW to LA (iso suspect DV but pt denies), also ligature marks to neck. WC placed, CT (-).

Which is to say

The ambulance brought them to the ED for a gunshot wound to the left arm. We’re pretty sure the spouse tried to shoot them and it looks like they tried to strangle them too, but they won’t admit it / is covering for them. The wound consult is in and they did a CT of their neck already, no severe injury noted.

…which is like three times as long.
