Initial contact will be made by the clinical team, but follow up by a research midwife to discuss the research study in detail will be made, either by telephone, or face-to-face following the clinical consultation wherever possible. This is to minimize potential conflicts from having the clinicians obtain patient consent for the study. Patients will be reassured that they will be under no obligation to participate and that their decision will not affect their clinical care or relationship with their treating medical practitioner Written, informed consent will be obtained from women prior to their procedure and be stored in a locked filing cabinet in the respective Departments of Perinatal Medicine.
