Other datasets from AHRQ are available; dates vary by dataset. | Online and signed data use agreements and training course are required. | $50–150/dataset for students $350–500 for researchers |
American Association of Birth Centers (AABC) Perinatal Data Registry | The registry, originally designed for birth centers, now includes data from diverse perinatal settings and care providers. Women are enrolled at the first prenatal visit, and data entered at key time points in perinatal care, resulting in prospective enrollment ahead of perinatal outcomes. | Data from 2007- forward is available. | Scientific data request form must be submitted along with IRB approval. All abstracts, manuscripts, and publications must be approved by the AABC Research Committee and Board of Directors prior to submission. |

Listening to Mothers | National survey of women in the US who gave birth to a singleton baby. Includes information on pregnancy planning, care providers, labor support, labor onset, perinatal medical interventions, breastfeeding, feelings about care during labor and birth, treatment by caregivers, description of labor and birth experiences, general postpartum health, and emotional health after birth. | Listening to Mothers (2002; N = 1,583) Listening to Mothers II (2006; N = 1,573), Listening to Mothers III (2012; N = 2,400) Listening to Mothers II: New Mothers Speak Out (2006; n = 903), Listening to Mothers III: New Mothers Speak Out (2013; n = 1,072) | Check with internal IRB; generally non-human subjects research and exempt from IRB oversight.

Midwives Alliance of North America Statistics Project (MANA Stats) | Datasets include 3 iterations: 2.0, 3.0, and the current 4.0, each with different variables. Midwives enroll patients early in prenatal care and enter data as perinatal events unfold; thus, data are prospectively collected. Once entered, records cannot be deleted. Most data are from planned homebirth or birth center care; ~12% of study participants have intrapartum hospital transfer and data include outcomes after transfer. | 2.0 (2004–2009; N=24,000), 3.0 (2009–2011; N=15,000), 4.0 (2011–current; N=61,000) with approximately 1100 added each month | First, propose research question to MANA Research Review Committee. If approved, complete MANA application includes: description of project and research questions, methods/procedures, risks/benefits assessment, dissemination plan, timeline, funding summary, references, list of variables requested, CVs and documentation of human research ethics training for all investigators, and IRB approval. | Students- $100 Faculty at large research institutions- $1000 Faculty at smaller research institutions- $250 |
