Using Multivariate Statistics

Evaluating the quality of medical care.

Identifying the women at risk of antenatal anxiety and depression: A systematic review.

Background
Cardiotocography (CTG) records changes in the fetal heart rate and their temporal relationship to uterine contractions. The aim is to identify babies who may be short of oxygen (hypoxic) to guide additional assessments of fetal wellbeing, or determine if the baby needs to be delivered by caesarean section or instrumental vaginal birth. This is an update of a review previously published in 2013, 2006 and 2001.

Objectives
To evaluate the effectiveness and safety of continuous cardiotocography when used as a method to monitor fetal wellbeing during labour.

Search methods
We searched the Cochrane Pregnancy and Childbirth Group Trials Register (30 November 2016) and reference lists of retrieved studies.

Selection criteria
Randomised and quasi-randomised controlled trials involving a comparison of continuous cardiotocography (with and without fetal blood sampling) with no fetal monitoring, intermittent auscultation intermittent cardiotocography.

Data collection and analysis
Two review authors independently assessed study eligibility, quality and extracted data from included studies. Data were checked for accuracy.

Main results
We included 13 trials involving over 37,000 women. No new studies were included in this update.

One trial (4044 women) compared continuous CTG with intermittent CTG, all other trials compared continuous CTG with intermittent auscultation. No data were found comparing no fetal monitoring with continuous CTG. Overall, methodological quality was mixed. All included studies were at high risk of performance bias, unclear or high risk of detection bias, and unclear risk of reporting bias. Only two trials were assessed at high methodological quality.

Compared with intermittent auscultation, continuous cardiotocography showed no significant improvement in overall perinatal death rate (risk ratio (RR) 0.86, 95% confidence interval (CI) 0.59 to 1.23, N = 33,513, 11 trials, low quality evidence), but was associated with halving neonatal seizure rates (RR 0.50, 95% CI 0.31 to 0.80, N = 32,386, 9 trials, moderate quality evidence). There was no difference in cerebral palsy rates (RR 1.75, 95% CI 0.84 to 3.63, N = 13,252, 2 trials, low quality evidence). There was an increase in caesarean sections associated with continuous CTG (RR 1.63, 95% CI 1.29 to 2.07, N = 18,861, 11 trials, low quality evidence). Women were also more likely to have instrumental vaginal births (RR 1.15, 95% CI 1.01 to 1.33, N = 18,615, 10 trials, low quality evidence). There was no difference in the incidence of cord blood acidosis (RR 0.92, 95% CI 0.27 to 3.11, N = 2494, 2 trials, very low quality evidence) or use of any pharmacological analgesia (RR 0.98, 95% CI 0.88 to 1.09, N = 1677, 3 trials, low quality evidence).

Compared with intermittent CTG, continuous CTG made no difference to caesarean section rates (RR 1.29, 95% CI 0.84 to 1.97, N = 4044, 1 trial) or instrumental births (RR 1.16, 95% CI 0.92 to 1.46, N = 4044, 1 trial). Less cord blood acidosis was observed in women who had intermittent CTG, however, this result could have been due to chance (RR 1.43, 95% CI 0.95 to 2.14, N = 4044, 1 trial).

Data for low risk, high risk, preterm pregnancy and high-quality trials subgroups were consistent with overall results. Access to fetal blood sampling did not appear to influence differences in neonatal seizures or other outcomes.

Evidence was assessed using GRADE. Most outcomes were graded as low quality evidence (rates of perinatal death, cerebral palsy, caesarean section, instrumental vaginal births, and any pharmacological analgesia), and downgraded for limitations in design, inconsistency and imprecision of results. The remaining outcomes were downgraded to moderate quality (neonatal seizures) and very low quality (cord blood acidosis) due to similar concerns over limitations in design, inconsistency and imprecision.

Authors' conclusions
CTG during labour is associated with reduced rates of neonatal seizures, but no clear differences in cerebral palsy, infant mortality or other standard measures of neonatal wellbeing. However, continuous CTG was associated with an increase in caesarean sections and instrumental vaginal births. The challenge is how best to convey these results to women to enable them to make an informed decision without compromising the normality of labour.

The question remains as to whether future randomised trials should measure efficacy (the intrinsic value of continuous CTG in trying to prevent adverse neonatal outcomes under optimal clinical conditions) or effectiveness (the effect of this technique in routine clinical practice).

Along with the need for further investigations into long-term effects of operative births for women and babies, much remains to be learned about the causation and possible links between antenatal or intrapartum events, neonatal seizures and long-term neurodevelopmental outcomes, whilst considering changes in clinical practice over the intervening years (one-to-one-support during labour, caesarean section rates). The large number of babies randomised to the trials in this review have now reached adulthood and could potentially provide a unique opportunity to clarify if a reduction in neonatal seizures is something inconsequential that should not greatly influence women's and clinicians' choices, or if seizure reduction leads to long-term benefits for babies. Defining meaningful neurological and behavioural outcomes that could be measured in large cohorts of young adults poses huge challenges. However, it is important to collect data from these women and babies while medical records still exist, where possible describe women's mobility and positions during labour and birth, and clarify if these might impact on outcomes. Research should also address the possible contribution of the supine position to adverse outcomes for babies, and assess whether the use of mobility and positions can further reduce the low incidence of neonatal seizures and improve psychological outcomes for women.

Continuous cardiotocography (CTG) as a form of electronic fetal monitoring (EFM) for fetal assessment during labour

BackgroundMaternal anxiety negatively influences child outcomes. Reliable estimates have not been established because of varying published prevalence rates.AimsTo establish summary estimates for the prevalence of maternal anxiety in the antenatal and postnatal periods.MethodWe searched multiple databases including MEDLINE, Embase, and PsycINFO to identify studies published up to January 2016 with data on the prevalence of antenatal or postnatal anxiety. Data were extracted from published reports and any missing information was requested from investigators. Estimates were pooled using random-effects meta-analyses.ResultsWe reviewed 23 468 abstracts, retrieved 783 articles and included 102 studies incorporating 221 974 women from 34 countries. The prevalence for self-reported anxiety symptoms was 18.2% (95% CI 13.6-22.8) in the first trimester, 19.1% (95% CI 15.9-22.4) in the second trimester and 24.6% (95% CI 21.2-28.0) in the third trimester. The overall prevalence for a clinical diagnosis of any anxiety disorder was 15.2% (95% CI 9.0-21.4) and 4.1% (95% CI 1.9-6.2) for a generalised anxiety disorder. Postnatally, the prevalence for anxiety symptoms overall at 1-24 weeks was 15.0% (95% CI 13.7-16.4). The prevalence for any anxiety disorder over the same period was 9.9% (95% CI 6.1-13.8), and 5.7% (95% CI 2.3-9.2) for a generalised anxiety disorder. Rates were higher in low- to middle-income countries.ConclusionsResults suggest perinatal anxiety is highly prevalent and merits clinical attention. Research is warranted to develop evidence-based interventions.

Prevalence of antenatal and postnatal anxiety: systematic review and meta-analysis.

BACKGROUND:
The cesarean-section rate continues to rise in many countries with routine access to medical services, yet this increase is not associated with improvement in perinatal mortality or morbidity. A large number of commentaries in the medical literature and media suggest that consumer demand contributes significantly to the continued rise of births by cesarean section internationally. The objective of this article was to critically review the research literature concerning women’s preference or request for elective cesarean section published since that critiqued by Gamble and Creedy in 2000. 

METHODS:
A search of key databases using a range of search terms produced over 200 articles, of which 80 were potentially relevant. Of these, 38 were research-based articles and 40 were opinion-based articles. A total of 17 articles fitted the criteria for review. A range of methodologies was used, with varying quality, making meta-analysis of findings inappropriate, and simple summaries of results difficult to produce. Results: The range and quality of studies had increased since 2001, reflecting continuing concern. Women’s preference for cesarean section varied from 0.3 to 14 percent; however, only 3 studies looked directly at this preference in the absence of clinical indications. Women’s preference for a cesarean section related to psychological factors, perceptions of safety, or in some countries, was influenced by cultural or social factors. 

CONCLUSIONS: 
Research between 2000 and 2005 shows evidence of very small numbers of women requesting a cesarean section. A range of personal and societal reasons, including fear of birth and perceived inequality and inadequacy of care, underpinned these requests

Elective cesarean section and decision making: a critical review of the literature

Aim. To investigate pre- and postpartum levels of childbirth fear in a cohort of childbearing women and explore the relationship to birth outcomes. Background. While results are mixed, there is evidence that fear of childbirth is associated with mode of birth. Limited theoretical work around childbirth fear has been undertaken with Australian women. Design. A prospective correlation design. Method. Women (n = 401) completed the Wijma Delivery Expectancy/Experience Questionnaire (W-DEQ) version A at 36 weeks gestation, with 243 (61%) women also completing version B at six weeks postpartum. Scores were summarised with means and standard deviations. Content analysis of the free statements identified nine issues of concern. Results. Twenty-six per cent of pregnant women reported low levels of childbirth fear, 48% were moderately fearful and 26% were highly fearful. Fear decreased after birth for those women in the high antenatal fear group, however surgical intervention at birth (n = 238, anova, F1,230 = 12糹, p = 0簰1) and suspected fetal compromise (F1,230 = 4糳, p = 0簳9) increased levels of postpartum fear. Univariately, high antenatal fear was associated with emergency caesarean delivery (n = 324, Wald 5簵, p = 0簲5) however after adjustment for nulliparity and fetal compromise the association disappeared. Australian-born women were more likely to report higher levels of fear and experience higher rates of caesarean section than participants of non-Australian origin. Conclusions. Results support those from earlier studies in showing that nulliparous women experience more fear than parous women before birth and that there is no difference in levels of postpartum fear between these two groups. Fear levels were higher in Australian women when compared to a Swedish sample. Relevance to clinical practice. The results of this study add to our preliminary understanding of the phenomena of childbirth fear within an Australian context and are particularly useful in profiling women for whom secondary fear of childbirth is more likely to occur.

Pre‐ and postpartum levels of childbirth fear and the relationship to birth outcomes in a cohort of Australian women

Background:Few studies have examined women's preferences for birth. The object of this study was to determine the incidence of women's preferred type of birth, and the reasons and factors associated with their preference.Methods:Three hundred and ten women between 36 and 40 weeks' gestation were recruited from the antenatal clinic of a major metropolitan teaching hospital and the consulting rooms of six private obstetricians in Brisbane, Australia. Participants completed a questionnaire asking about their preferred type of birth, reasons for their preference, preparation for childbirth, level of anxiety and concerns, and the influence of the primary caregiver.Results:Two hundred and ninety women (93.5%) preferred a spontaneous vaginal birth; 20 women (6.4%) preferred a cesarean section. Of the latter group, most had a current obstetric complication or experienced a previously complicated delivery (p <0.001); 1 woman (0.3%) preferred a cesarean section in the absence of any known current or previous obstetric complication. Women who preferred a cesarean section were more anxious, were generally poorly informed of the risks of this procedure, and/or overestimated the safety of the procedure.Conclusions:Women who preferred a cesarean section were more likely to have experienced this type of birth previously and to have negative feelings about it. To decrease women's preference for a cesarean section, practitioners should reduce the primary cesarean delivery rate and improve the quality of emotional care for women who require a cesarean section. Caregivers should engage in a sensitive discussion of the risks and benefits of various birth options, including a vaginal birth after cesarean, with women who have previously experienced a cesarean birth before they make decisions about mode of delivery in a subsequent pregnancy.

Women's preference for a cesarean section: incidence and associated factors

Adverse childbirth experiences can evoke fear and overwhelming anxiety for some women and precipitate posttraumatic stress disorder. The objective of this study was to assess a midwife‐led brief counseling intervention for postpartum women at risk of developing psychological trauma symptoms. Method: Of 348 women screened for trauma symptoms, 103 met inclusion criteria and were randomized into an intervention (n = 50) or a control (n = 53) group. The intervention group received face‐to‐face counseling within 72 hours of birth and again via telephone at 4 to 6 weeks postpartum. Main outcome measures were posttraumatic stress symptoms, depression, self‐blame, and confidence about a future pregnancy. Results: At 3‐month follow‐up, intervention group women reported decreased trauma symptoms, low relative risk of depression, low relative risk of stress, and low feelings of self‐blame. Confidence about a future pregnancy was higher for these women than for control group women. Three intervention group women compared with 9 control group women met the diagnostic criteria for posttraumatic stress disorder at 3 months postpartum, but this result was not statistically significant. Discussion: A high prevalence of postpartum depression and trauma symptoms occurred after childbirth. Although most women improved over time, the intervention markedly affected participants' trajectory toward recovery compared with women who did not receive counseling. Conclusions: A brief, midwife‐led counseling intervention for women who report a distressing birth experience was effective in reducing symptoms of trauma, depression, stress, and feelings of self‐blame. The intervention is within the scope of midwifery practice, caused no harm to participants, was perceived as helpful, and enhanced women's confidence about a future pregnancy.
