SQL expression to python expression

Hi

I have a SQL expression that I use in Make Feature Layer in Model Builder ("HOSPITAL" = '% HOSPITALNAME%'). The expression makes a selection in a OD Cost Matrix that a patient is patient only at one hospital and not all hospitals as an OD Cost Matrix would normally do. HOSPITAL is a column in orgins in add location and HOSPITALNAME is a column in the DESTINATION to add location.
What I wonder is how this expression will be in a python script?
I've tried something like this in python in the expression field in arcpy.MakeFeatureLayer "'HOSPITAL' = '" + HOSPITAL NAME + "'". But it does not works. I don't get any error message but it only runs OD Cost Matrix normally.

Can anyone help me with this?
