…And when the support person isn’t a hospital staffer or known to the patient
The Cochrane Review also evaluated different types of labor supporters: companions of the patient’s choice from her social network, hospital employees, and people who were neither. The support person conferred significant benefit only when that person was neither hospital staff nor a member of the woman’s social network.
Hospital staff members who provided support didn’t effectively decrease the C-section rate (12% rate in control group vs 11.3% in supported group; P=.28). Support people chosen by the patient likewise didn’t successfully reduce C-sections (19.4% control rate vs 15.5% supported rate; P=.062). When the support person was neither hospital staff nor someone well-known to the patient, the risk of C-section was significantly lower (ARR=6%; NNT=17; P=.0003).
In a Comparative Effectiveness Review published in October 2012, the Agency for Healthcare Research and Quality investigated 18 strategies to reduce C-section, one of which was psychosocial support from doulas and other providers. A trained support person was the only intervention that showed evidence of benefit in decreasing C-section, but the strength of evidence was low.2
An American College of Obstetricians and Gynecologists Practice Bulletin recommends continuous labor support, noting “the continuous presence of a support person may reduce the likelihood of…operative delivery” with no apparent harmful effects.3
