What are practices/policies at other large institutions to ensure that all obstetric patients that are RhIG candidates receive their RhIG? Do you require a type and screen on all obstetric patients, or are prenatal records acceptable? How do you ensure that all Rh negative obstetric women at your institution have a rhogam evaluation - nursing or blood bank oversight? Also, how soon after delivery are your rhogam evaluation samples drawn, and what are your practices surrounding this?
