Shadowing.... unique to DO.... so far as I have found.... purpose is to see what makes up the day of a physician specifically DO...
May last four hours to a month.... depends on who you know....
I shadowed three docs for a day each.... worked out well
also shadowed some MD's for longer periods....
All desired to help me get into MS...
Also, the DO you shadow will likely be the DO to write you an LOR... letter of recommendation....
hope this helps....
PM if you need
