Well, I can think of some to avoid, if it helps. I'm interpreting hospital as any scenes in hospitals or doctors' offices.
Freeter ie o Kau
Kekkon Dekinai Otoko
Late Blooming Sunflower
Marumo no Ikete
dear sister (family cohabitation drama)
37.5 no namida
Itsuka Kono Koi wo Omoidashite Kitto Naite Shimau
The hours of my life boku no ita jikan
soshite dare mo inakunatta
n no tame ni
Suteki na sen taxi
10 kuroi no onna
flowers for algernon
I'm pretty sure all of these you will want on your avoid list. I'll try to think of which I've seen don't have any such scenes.
