Accuracy in Reporting of Kentucky Certified Nurse-Midwives as Attendants in Birth Registration Data.

Introduction: Birth certificate data are used nationally to determine health care policy and health care reimbursement and to demonstrate the legitimacy and value of certified nurse-midwives (CNMs) and certified midwives (CMs) in perinatal and neonatal outcomes. However, the validity of birth certificate data is questionable, in part because of the data collection process. These data are particularly crucial for midwife-attended births because the correct birth attendant is not always accurately identified on the birth certificate.
