Planned Home Birth in Low-Risk Pregnancies in Spain: A Descriptive Study
Abstract
:1. Introduction
Objective
- -
- Specific objectives of the sociodemographic variables:
- -
- To explore the sociodemographic characteristics of women who choose this type of delivery.
- -
- Specific objectives of clinical variables:
- -
- To know the characteristics of home birth, mode of birth, its length and its relationship with maternal age and parity, and, in relation to the need to be transferred to hospital, the causes, timing and factors on which the transfer depended and where these deliveries were finished (at home or in hospital).
- -
- To determine the rate of breastfeeding and participation in maternal education of women who planned a home delivery.
- -
- To identify the complications that birth at home entails for the mother and the newborn health and their association with parity, maternal age and gestational age.
- -
- To identify the maternal and neonatal mortality rate among deliveries that were planned to take place at home.
- -
- Specific objectives of variables of professional intervention:
- -
- To highlight the obstetric interventions in childbirth and immediate postpartum planned at home, and its relationship to the length of delivery.
2. Materials and Methods
2.1. Design and Setting
- ○
- Deliveries registered with standardized data collection form as established by the Guide to Home Birth Assistance [36].
- ○
- Women who planned to give birth at home had to meet the criteria set forth in the Guide to Home Birth Assistance [36], to accept the request for accompaniment of home birth, which included the following:
- ○
- The home birth plan is established before 28 weeks of gestation.
- ○
- A minimum of four clinic visits before delivery.
- ○
- The women must provide all the ultrasound and analytical controls and other necessary complementary tests that have been carried out.
- ○
- Low-risk pregnancy, according to the “Guide to Clinical Practice for Childbirth Assistance” updated in 2018.
- ○
- Maternal body mass index (BMI) ≤ 30 Kg/m2 at the beginning of pregnancy.
- ○
- Clinical history without relevant complications.
- ○
- Uncomplicated obstetric history (no previous cesarean sections).
- ○
- ○
- The choice to give birth at home as an informed and free decision.
- ○
- Multiple pregnancy.
- ○
- Non-cephalic.
- ○
- Start of delivery before week 37 or after week 42.
- ○
- Qualification of the personnel assisting the delivery other than Obstetric-Gynecological nurses, or the absence of registration or civil liability insurance.
- ○
- Distance between the home where delivery is intended and the reference hospital greater than 45 min by car.
