potential new terms for OGMS

[mbrochhausen]

For an NIH-funded project (https://reporter.nih.gov/search/xixj9AYmyku-lJmgln8C_Q/project-details/10681388) we need ontological representation of
patient mortality,
length of stay
major complications.

In addition to those three we are going to require additional health outcome measures as the project progresses.

I am wondering whether those three are terms that would fall under the OGMS scope.
