  • Epidemiology
  1. Incidence of Planned Out-Of-Hospital Birth
    1. U.S.: 1.6% in 2018 (accounting for 1 in 61 births; births were at home for 63% in 1935)
  2. Locations for out of hospital Births (U.S.)
    1. Home Birth: 62%
    2. Free-Standing Birthing Center: ~33%
      1. As of 2016, U.S. had <400 birth centers, and only 119 are accredited by American Association of Birth Centers
  3. Provider Attendeding Planned Out-Of-Hospital Birth (U.S.)
    1. Midwives represent >95%
    2. Physician: ~4%
  4. Many U.S Home Births are performed in "maternity care deserts" where there are no obstetricians or hospitals
    1. More than 1000 U.S. counties with >5 million population have no obstetrician or hospital
  5. One third of U.S. out-of-hospital deliveries are not considered low risk (i.e. considered contraindicated by ACOG)
    1. Vaginal Birth after Cesarean (VBAC) attempts at home have increased despite increased risk
    2. Patients may choose risk of Home Birth, as many hospitals do not allow Trial of Labor after Cesarean

  • Precautions
  1. Out-Of-Hospital Birth here refers only to a planned Community Birth
    1. Unattended Home Birth (free birth) and precipitous delivery are not addressed here
    2. Unattended Home Birth (free birth) is associated with 90 fold increased maternal mortality
  2. AAP and ACOG have statements regarding planned Home Birth
    1. AAP and ACOG point out that hospitals and accredited birth centers are safest birth locations
    2. AAP does not recommend Home Birth, but recommend a second provider for newborn if Home Birth is performed
    3. ACOG lists strict indications, highlighting risks and benefits (as below)
  3. Midwives
    1. Midwife should meet standards (International Confederation of Midwives Global Standards of Midwifery Education)
    2. Guidelines vary by U.S. state, as to who may assist a planned home delivery
    3. Midwives in U.S. have 4 distinct pathways of education (Certified Nurse Midwife, Certified Midwife, Traditional Midwife)
      1. Certified Nurse Midwives are nurses who are also midwives trained at a formal college program
      2. Certified Midwives (direct entry midwives) are non-nurses trained at a formal college program
        1. Most certified midwives are Certified Professional Midwives, undergoing additional certification
        2. Additional Certification may be in the form of accredited program or portfolio evaluation process
      3. Traditional midwives may not be certified, licensed or undergo formal training
  4. Emergencies
    1. Standardized protocols should be established for safe and timely Emergency Transport and hospital evaluation if needed
  • Efficacy
  1. See complications below
  2. Unattended Home Birth and precipitous delivery have different risks and outcomes not addressed here
  3. Compared with hospital birth, Home Births have lower rates of obstetric intervention
    1. Decreased risk of assisted Vaginal Delivery
    2. Decreased risk of cesarean delivery
  • Complications
  1. Per ACOG, Planned Out-Of-Hospital Births approximately double risk of these adverse outcomes
  2. Neonatal Death (1-2 per 1000 planned Home Births)
    1. Neonatal death rates increase to 1 in 78 for home Breech Delivery
    2. Neonatal death rates are also higher for Home Births to Nulliparous mothers, and Gestational age >41 weeks
  3. Neonatal Seizures or serious neurologic dysfunction (0.4 to 0.6 per 1000 Home Births)
    1. Risk increases 8 fold over in-hospital delivery if home Vaginal Birth after Cesarean section
  4. Low APGAR Score
  • Management
  • Newborn Care

      1. Group B Streptococcal Sepsis
