RESUMEN
Brazil has a cesarean rate of 56% and low use of Intrapartum Evidence-based Practices (IEBP) of 3.4%, reflecting a medically centered and highly interventionist maternal health care model. The Senses of Birth (SoB) is a health education intervention created to promote normal birth, use of EBP, and reduce unnecessary c-sections. This study aimed to understand the use of intrapartum EBP by Brazilian women who participated in the SoB intervention. 555 women answered the questionnaire between 2015 and 2016. Bivariate analysis and ANOVA test were used to identify if social-demographic factors, childbirth information, and perceived knowledge were associated with the use of EBP. A qualitative analysis was performed to explore women's experiences. Research participants used the following EBP: birth plan (55.2%), companionship during childbirth (81.6%), midwife care (54.2%), freedom of mobility during labor (57.7%), choice of position during delivery (57.2%), and non-pharmacological pain relief methods (74.2%). Doula support was low (26.9%). Being a black woman was associated with not using a birth plan or having doula support. Women who gave birth in private hospitals were more likely not to use the EBP. Barriers to the use of EBP identified by women were an absence of individualized care, non-respect for their choices or provision of EBP by health care providers, inadequate structure and ambiance in hospitals to use EBP, and rigid protocols not centered on women's needs. The SoB intervention was identified as a potential facilitator. Women who used EBP described a sense of control over their bodies and perceived self-efficacy to advocate for their chosen practices. Women saw the strategies to overcome barriers as a path to become their childbirth protagonist. Health education is essential to increase the use of EBP; however, it should be implemented combined with changes in the maternal care system, promoting woman-centered and evidence-based models.
