Evidence On Doulas

The following text and photo is excerpted from "Evidence on: Doulas" a recent article August 14, 2017 by Rebecca Dekker, on her incredibly informative website, Evidence Based Birth. You can read the full text of her article here: https://evidencebasedbirth.com/the-evidence-for-doulas/


Why are doulas so effective? 

There are several reasons why we think doulas are so effective. The first reason is the “harsh environment” theory. In most developed countries, ever since birth moved out of the home and into the hospital, laboring people are frequently submitted to institutional routines, high intervention rates, staff who are strangers, lack of privacy, bright lighting, and needles.

Most of us would have a hard time dealing with these conditions when we’re feeling our best. But people in labor have to deal with these harsh conditions when they are in a very vulnerable state. These harsh conditions may slow down a person’s labor and their self-confidence. It is thought that a doula “buffers” this harsh environment by providing continuous support and companionship which promotes the mother’s self-esteem (Hofmeyr, Nikodem et al. 1991).

A second reason that doulas are effective is because doulas are a form of pain relief in themselves (Hofmeyr, 1991). With continuous support, laboring people are less likely to request epidurals or pain medication. It is thought that there is fewer use of medications because birthing people feel less pain when a doula is present. An additional benefit to the avoidance of epidural anesthesia is that women may avoid many medical interventions that often go along with an epidural, including Pitocin augmentation and continuous electronic fetal monitoring (Caton, Corry et al. 2002).

This finding—that people with doulas are less likely to have an epidural—is not due to the fact that clients with doulas in these studies were more likely to want these things up front and were more motivated to achieve them. In fact, randomized trials account for these differences—this is why they are called randomized, controlled trials. The people assigned to have a doula, and those assigned to not have a doula, are randomly assigned, meaning that the same percentage in each group would have a desire for an unmedicated birth.

A third reason why doulas are effective has to do with the attachment between the birthing person and doula which can lead to an increase in oxytocin, the hormone that promotes labor contractions. This theory was proposed by Dr. Amy Gilliland in her 2010a study about effective labor support. In personal correspondence with Dr. Gilliland, she wrote, “I believe the Doula Effect is related to attachment. When the mother feels vulnerable in labor, she directs attachment behaviors to suitable figures around her, who may or may not be her attachment figures (parent, mate). When the mother directs attachment seeking behaviors to the doula, the experienced doula (25 births or more) responds in a unique manner. She is able to respond as a secure base, thereby soothing the mother’s attachment system. The accompanying diminishment in stress hormones allows for a surge in oxytocin in both the mother and the doula… theoretically, oxytocin is the hormone of attachment, and it is released during soothing touch and extended eye contact, which are habitual behaviors of birth doulas.” (Personal communication, Dr. Amy Gilliland, July 2015).

Swedish oxytocin researcher Kristin Uvnas Moberg writes that the doula enhances oxytocin release which decreases stress reactions, fear, and anxiety, and increases contraction strength and effectiveness. In addition, the calming effect of the doula’s presence increases the mother’s own natural pain coping hormones (beta-endorphins), making labor feel less painful (Uvnas Moberg, 2014).

Based on the evidence, I have come up with a conceptual model of how doula support influences outcomes.

A conceptual model  is what researchers use to try and understand how a phenomenon works. Here is my conceptual model on the phenomenon of doula support.

The Cesarean Rate Epidemic

Abby BlockComment

This article looks at the current rates, state, and climate of Cesarean Births in the U.S. It provides statistics and rates, reasons for Cesareans, as well as the associated risks. 

Cesarean delivery may be a safe alternative to vaginal delivery but its use in 1 of 3 women giving birth in the US seems to high.
— contemporaryobgyn.modernmedicine.com

An excerpt discussing the rising rates and unusual number of Cesarean rates below:

"One possible reason for the rise in the cesarean delivery rate may be that there has simply been a rise in the need for cesarean. The most common indication for a primary cesarean is cephalo-pelvic disproportion, or arrest of progress in labor. It is unlikely that maternal pelvis size has changed over the past 3 decades, but it is possible that birth weight has increased. In fact, evidence suggests that rates of macrosomia have increased over the past 2 decades.8 Other issues that contribute to increasing rates of cesarean delivery, possibly through the mechanism of birth weight, are maternal obesity and gestational weight gain.9,10 Without question, the proportion of obese women has increased over the past decade and higher weight classes are associated with even higher rates of cesarean.11,12 In addition, increased gestational weight gain has been associated with cesarean delivery and is commonly above standard guidelines.13

Another reason for increasing cesarean rates may be a rise in elective cesarean delivery, also known as cesarean delivery by maternal request (CDMR). Because there was no ICD-9 code for CDMR, it is unclear what proportion of cesareans are due to it. One recent study, however, estimated the proportion as high as 4% in the United States.14 Interestingly, CDMR is more common in other countries, such as Brazil, Taiwan, and Chile. A study in Chile comparing women receiving private care (cesarean rate >40%) to women receiving public care (cesarean rate <20%) found that 8% of those receiving private care and 11% of those receiving public care stated a preference for cesarean delivery, with the vast majority preferring to deliver vaginally.15 Thus, even in this setting, it is unclear that maternal preferences are driving the increase in cesarean delivery rate."

US C-Sections Rate: Too High

Abby BlockComment

If you've been or are pregnant in NYC,  probably one of the first things you did was to figure out who your doctor would be and where you would give birth. You may have spent hours googling something like "NYC OB low cesarean rate," or "NYC hospital low c-section rate." And you may or may not have found the answers you were looking for. Consumer Reports just released an article reviewing the current state of cesarean births and rates by hospitals around the country. Many of the hospitals in NYC that my clients have given birth in do not release their statistics. Considering that your biggest Cesarean risk might be the hospital that you give birth in, withholding c-section rates by hospital (and even by practice or doctor) just doesn't seem ethical.
