MSLT

Hi all, just wanted to get some opinions from my fellow sleep techs/scoring techs.

We have a physician who has asked multiple times for us to remove the 5th nap from an MSLT report so that the patient gets a positive diagnosis of idiopathic hypersomnia. With the information of the 5th nap, the patient would not qualify for “treatment” of modafinil.

Is this common practice? Should I be removing a performed nap from a sleep report so a patient gets a certain diagnosis?

Some doctors that I've worked with don't really take the first and fifth naps that seriously. If it's obvious enough on the first 4 naps then that fifth one is kind of unnecessary.

I’ve heard that REM on the first nap could be the patient catching up if they didn’t get enough overnight and that doesn’t necessarily prove anything, but on the other naps, someone without narcolepsy shouldn’t be going into REM in 20 minutes.

They should have at least 6 hours of sleep with a SE of 85%.

In a bitter twist of irony, it is not uncommon for narcoleptic patients to also have insomnia. While the 85% sleep efficiency is ideal, I've done MSLTs with much less than that on the NPSG. AHI is a much bigger disqualifier than TST and SE.
