You could also go to File > "Report Options" and check the "Convert database null values to default" option and a null field will be replaced by an empty string.  That option will effect almost every formula in a report, so if you actually need to see nulls in some formulas, you may not want to use that option.

 More recent versions of CR also include an option in the formula editor to control how that specific formula treats nulls, so you could see if you have that option.

Try this

Local StringVar strOutput;
If Not IsNull({Patients.NsID}) Then
    strOutput := {Patients.NsID} + " / "
Else
    strOutput  := " / ";

If Not IsNull({Patients.Room}) Then
    strOutput  := strOutput  + {Patients.Room} + " / "
Else
    strOutput  := strOutput  + " / ";

If Not IsNull({Patients.Bed}) Then
    strOutput  := strOutput  + {Patients.Bed};

strOutput
