In BrE, “hospital” (no article) is normally used in contexts that refer to patients receiving treatment: “I was in hospital for a month”, “Hospital is grim”, “He needs to go to hospital”.

In other cases articles are used: “She goes to work at the hospital each day”, “The new hospital is almost finished”.

Please remember that in American English:

I will be IN THE hospital for a week. (As a patient)

I was AT THE hospital for an hour. (As a visitor)
