Inconsistent Evidence: Analysis of Six National Guidelines for Vaginal Birth After Cesarean Section

Abstract: Background: Guidelines are increasingly used to direct clinical practice, with the expectation that they improve clinical outcomes and minimize health care expenditure. Several national guidelines for vaginal birth after cesarean section (VBAC) have been released or updated recently, and their range has created dilemmas for clinicians and women. The purpose of this study was to summarize the recommendations of existing guidelines and assess their quality using a standardized and validated instrument to determine which guidelines, if any, are best able to guide clinical practice. Methods: English language guidelines on VBAC were purposively selected from national and professional organizations in the United Kingdom, United States, Canada, New Zealand, and Australia. The Appraisal of Guidelines for Research and Evaluation (AGREE) instrument was applied to each guideline, and each was analyzed to determine the range and level of evidence on which it was based and the recommendations made. Results: Six guidelines published or updated between 2004 and 2007 were examined. Only two of the six guidelines scored well overall using the AGREE instrument, and the evidence used demonstrated great variety. Most guidelines cited expert opinion and consensus as evidence for some recommendations. Reported success rates for VBAC ranged from 30 to 85 percent, and reported rates of uterine rupture ranged from 0 to 2.8 percent. Conclusions: VBAC guidelines are characterized by quasi‐experimental evidence and consensus‐based recommendations, which lead to wide variability in recommendations and undermine their usefulness in clinical practice.

Giving Birth in Two Maternity Hospitals in Lithuania

Abstract: Background: In many hospitals in former Soviet countries, traditional Soviet perinatal policies remain in place, although in others reforms have been introduced. This study explores women’s experiences during labor and birth in two Lithuanian maternity hospitals. The hospitals differed in that one (S) followed traditional Soviet era maternity practices whereas the other (P) had been exposed to World Health Organization‐Euro practices and policies with respect to more up‐to‐date evidence‐based and family‐centered care. Methods: Consecutive women giving birth in the two maternity hospitals were asked to participate in a survey. Completed responses were obtained from 416 women in one hospital (P) and 304 in the other hospital (S) representing 92.4 and 67.5 percent response rates, respectively. Results: Rates of interventions in both hospitals were similarly high with, however, P hospital being more likely to be sensitive to women’s psychosocial needs, such as being allowed to eat and drink more often during labor, and to have their husband or partner with them for labor and birth. Conclusion: It appears that in Lithuania, as in many parts of the world, introducing changes to the clinical care of birth takes time, and psychosocial changes may be easier to introduce than alterations in clinical practice.

Planned Place of Birth in New Zealand: Does it Affect Mode of Birth and Intervention Rates Among Low‐Risk Women?

Abstract: Background: Midwives providing care as lead maternity caregivers in New Zealand provide continuity of care to women who may give birth in a variety of settings, including home, primary units, and secondary and tertiary level hospitals. The purpose of this study was to compare mode of birth and intrapartum intervention rates for low‐risk women planning to give birth in these settings under the care of midwives. Methods: Data for a cohort of low‐risk women giving birth in 2006 and 2007 were extracted from the Midwifery Maternity Provider Organisation database. Mode of birth, intrapartum interventions, and neonatal outcomes were compared with results adjusted for age, parity, ethnicity, and smoking. Results: Women planning to give birth in secondary and tertiary hospitals had a higher risk of cesarean section, assisted modes of birth, and intrapartum interventions than similar women planning to give birth at home and in primary units. The risk of emergency cesarean section for women planning to give birth in a tertiary unit was 4.62 (95% CI: 3.66–5.84) times that of a woman planning to give birth in a primary unit. Newborns of women planning to give birth in secondary and tertiary hospitals also had a higher risk of admission to a neonatal intensive care unit (RR: 1.40, 95% CI: 1.05–1.87; RR: 1.78, 95% CI: 1.31–2.42) than women planning to give birth in a primary unit. Conclusions: Planned place of birth has a significant influence on mode of birth and rates of intrapartum intervention in childbirth. (BIRTH 38:2 June 2011)     

Posttraumatic Stress Disorder in New Mothers: Results from a Two‐Stage U.S. National Survey

Abstract: Background: Prevalence rates of women in community samples who screened positive for meeting the DSM‐IV criteria for posttraumatic stress disorder after childbirth range from 1.7 to 9 percent. A positive screen indicates a high likelihood of this postpartum anxiety disorder. The objective of this analysis was to examine the results that focus on the posttraumatic stress disorder data obtained from a two‐stage United States national survey conducted by Childbirth Connection: Listening to Mothers II (LTM II) and Listening to Mothers II Postpartum Survey (LTM II/PP). Methods: In the LTM II study, 1,373 women completed the survey online, and 200 mothers were interviewed by telephone. The same mothers were recontacted and asked to complete a second questionnaire 6 months later and of those, 859 women completed the online survey and 44 a telephone interview. Data obtained from three instruments are reported in this article: Posttraumatic Stress Disorder Symptom Scale‐Self Report (PSS‐SR), Postpartum Depression Screening Scale (PDSS), and the Patient Health Questionnaire‐2 (PHQ‐2). Results: Nine percent of the sample screened positive for meeting the diagnostic criteria of posttraumatic stress disorder after childbirth as determined by responses on the PSS‐SR. A total of 18 percent of women scored above the cutoff score on the PSS‐SR, which indicated that they were experiencing elevated levels of posttraumatic stress symptoms. The following variables were significantly related to elevated posttraumatic stress symptoms levels: low partner support, elevated postpartum depressive symptoms, more physical problems since birth, and less health‐promoting behaviors. In addition, eight variables significantly differentiated women who had elevated posttraumatic stress symptom levels from those who did not: no private health insurance, unplanned pregnancy, pressure to have an induction and epidural analgesia, planned cesarean birth, not breastfeeding as long as wanted, not exclusively breastfeeding at 1 month, and consulting with a clinician about mental well‐being since birth. A stepwise multiple regression revealed that two predictor variables significantly explained 55 percent of the variance in posttraumatic stress symptom scores: depressive symptom scores on the PHQ‐2 and total number of physical symptoms women were experiencing at the time they completed the LTM II/PP survey. Conclusion: In this two‐stage national survey the high percentage of mothers who screened positive for meeting all the DSM‐IV criteria for a posttraumatic stress disorder diagnosis is a sobering statistic.

Intrauterine endotoxin infusion in rat pregnancy induces preterm delivery and increases placental prostaglandin F2α metabolite levels

Objective: This study was designed to examine the effects of intrauterine endotoxin (lipopolysaccharide) on rat pregnancy. Study Design: Pregnant Sprague-Dawley rats (N = 26) were implanted with uterine catheters on day 15 or 16 of a 22-day gestation. Animals were randomly assigned to receive either lipopolysaccharide (25 or 50 μg) or sodium chloride solution (1 mL) on day 17 and then were either sacrificed on day 19 or observed until delivery. Placentas were harvested at the time of death, homogenates were prepared, and prostaglandin F_2α metabolite levels were determined by means of radioimmunoassay. Data were analyzed by analysis of variance, Student-Newman-Keuls, and Mann-Whitney tests. Results: Lipopolysaccharide-treated groups (25 and 50 μg) displayed a shorter interval to delivery (mean ± SE, 82 ± 13 and 63 ± 8 hours, respectively) than control animals (117 ± 3 hours). Pups of lipopolysaccharide-treated (25 and 50 μg) female animals had lower live birth weights (4.92 ± 0.01 and 5.12 ± 0.24 g, respectively) compared with control animals (6.04 ± 0.07 g). Placental homogenates from lipopolysaccharide-treated female animals contained higher levels of prostaglandin F_2α metabolite (1567 ± 64 and 1475 ± 59 pg/mL) than those from sodium chloride solution–infused control animals (804 ± 68 pg/mL). Conclusion: Bacterial products induce the preterm delivery of low-birth-weight pups in rats, possibly by increasing local prostaglandin biosynthesis. (Am J Obstet Gynecol 2000;182:1496-501.)     

Concurrent analysis: validation of the domains within the Birth Satisfaction Scale

Background and aim: Measuring women’s satisfaction with their birth experience has been problematic. Recently, an attempt has been made to capture birth satisfaction’s generalised meaning and incorporate it into an evidenced-based tool. Standard procedures for validation have limitations. Qualitative techniques such as domain analysis offer an alternative and assist in better understanding the importance of each item. This article examines the parsimony of the Birth Satisfaction Scale (BSS), which is a 30-item questionnaire designed to measure satisfaction with childbirth, with women’s actual experience of childbirth. Methods: Primary free text data collected from 207 women who originally tested the BSS was concurrently analysed with first-hand accounts of birth satisfaction collected from 19 qualitative papers. Results: The domain analysis confirmed three explanatory items within the BSS: ‘being in control’, ‘things going as planned’, and ‘being supported’. Conclusions: The BSS accounts for all the analysed data, suggesting it is a robust measure of satisfaction in childbirth. Strengths and limitations of the method are discussed, as are implications for practice. With further development, the instrument could be used to establish correlates with other psychometric measures, i.e. self-efficacy, anxiety, depression, locus of control and bonding; and evaluate models or care systems as a standalone instrument, or as a screening test prior to detailed qualitative work.     

Web-based News Reports on Midwives Compared with Obstetricians: A Prospective Analysis

Abstract: Background: The media both creates and reflects public opinion. The way in which health professionals are depicted in the media is likely to influence views held by and about different health professions. The aim of this study was to examine how midwives and obstetricians are reported in English language web-based news reports from around the world. Methods: News alerts from the Internet search engine Google were created to search for the terms “midwife,”“midwives,”“midwifery,”“obstetrics,” and “obstetricians.” These alerts were received over a 12-month period (May 1, 2006–April 31, 2007), downloaded, and analyzed using quantitative content analysis. Results: A total of 522 web-based news reports for midwifery and 564 for obstetrics (n = 1,086) were found. Dominant categories for midwives were: “mainstreaming midwives” (models of care/rise of midwifery) (28%); “the Cinderella of the maternity care” (workforce/industrial) (27%); “delivering the baby with your hands tied” (funding, insurance, and legislation) (21%); “ask the expert” (education, research, and health advice) (8%), “recognizing midwives” (awards and announcements) (7%), “unsafe midwives” (litigation) (6%); and “the art of birth” (books, film, and photographs) (2%). Dominant categories for obstetricians were: “ask the expert” (research and advice) (26%); “doctors are heroes amongst us” (awards and announcements) (19%); “obstetric workforce woes” (workforce/industrial) (19%); “new frontiers” (trends in care and new technology) (17%); “the disappearing obstetrician” (insurance and litigation) (10%); and “human-interest news reports” (9%). Obstetricians were more likely to be recognized as experts on pregnancy and birth and receive public recognition compared with midwives. Midwives were more likely to be depicted as struggling to be a mainstream option while being hampered by lack of funding, insurance, and legislative barriers. Conclusions: Although midwives have rising acceptance, they still struggle with recognition. Obstetricians have both acceptance and recognition. Countries where midwifery is a mainstream option have more news reports related to midwifery than obstetrics. Different issues appear more dominant in some countries, such as work force in the United Kingdom and funding, insurance, and legislation in the United States. (BIRTH 39:1 March 2012)     

The Politics of Home Birth in the United States

Home birth has emerged as a political issue in several states in the United States, and this essay examines two aspects of home births politics. First, legislative battles over home birth policy do not conform to our typical models of partisan (i.e., Democratic vs Republican) politics, and attempts at advocacy cannot rely on classical strategies of alignment with a dominant party in a state. Second, the debates over home birth have increasingly begun to parallel current partisan battles in their emotion and intensity with the related gridlock and reluctance to consider compromises that are often necessary to achieve policy goals. This essay calls for a greater willingness for all sides to approach home birth less as an ideological mission and more as a health policy challenge to support consumers interested in an integrated system of care.
