I try to stay off sdn due to the negativity, and that topics/threads usually dissolve away from the question into negativity.
With that said, there are some programs that save some dates/spots at the end for people that are last minute switches. When you look at the history of EM, and how many people came to EM from other fields, and how many schools don't have EM required (or the first exposure is very late), it makes sense to some people to keep some dates open in February. I know plenty of great EM docs that started off as something else from neuro to peds, with my first chair having done a full IM residency.
I saved about 20-30 spots for possibly interviewing late switches, last minute exposure to EM but loved it, etc... Some EM programs don't take people who have some prior training (plenty of good reasons why they may not), and others are able to / don't see it as a downfall. Lots of variety in the way people run their programs, none of them are wrong, just different personalities and beliefs.
So with that said, to answer the question, you can reach out to PDs, see how no SLOE would be interpreted, as prelim med you would likely rotate in the ED, so you can also try and get a non-standard SLOE from an EM physician you've interacted with or rotated with. You can always reach out to your EM rotation from med school and ask them if they recall you as well for a non-traditional SLOE.
As a final note, the flexibility of a schedule isn't always as flexible as people think outside EM. Residents and attendings groan about working holidays, or only having 2 or possibly 3 days grouped together as an 'off' holiday and not being able to fly home and back with significant time. Even though EM may be less shifts than an IM may work, usually you'll have to go into the hospital on a few days a month that may have been off due to conference once a week (unless it happens to be right before your shift) if your in residency or academics. I'm not saying its a bad thing, and I'd still choose it over, just things that aren't always obvious to people outside EM.
Good luck
