  1. 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).
