I sort of got trapped. If you have weapons on hand like firecrackers, you can commit "suicide" to get out, or, what I did was use the spud gun. You can shoot through the fence and hit the orderlies in the yard. If you stand close to the fence they can grab you and bust you.
Something else, there is a glitch that lets you walk through the rounded air conditioner near the door, give it a try.
