Note that the columns do not sum to the values in the 'Any obstetric condition' row because some admissions had more than one obstetric condition recorded in the four fields. ^aThe remaining 406 obstetric admissions (21.3%) were identified from a partial obstetric code (234) or by the text field search (172).
