To compare intensive and conventional therapy for severe fear of childbirth.
                In Finland, 176 women who had fear of childbirth were randomly assigned at the 26th gestational week to have either intensive therapy (mean 3.8 +/- 1.0 sessions with obstetrician and one with midwife) or conventional therapy (mean 2.0 +/- 0.6 sessions), with follow-up 3 months postpartum. Pregnancy-related anxiety and concerns, satisfaction with childbirth, and puerperal depression were assessed with specific questionnaires. Power analysis, based on previous studies, showed that 74 women per group were necessary to show a 50% reduction in cesarean rates.
                Birth-related concerns decreased in the intensive therapy group but increased in the conventional therapy group (linear interaction between the group and birth-concerns P =.022). Labor was shorter in the intensive therapy group (mean +/- standard deviation 6.8 +/- 3.8 hours) compared with the conventional group (8.5 +/- 4.8 hours, P =.039). After intervention, 62% of those originally requesting a cesarean (n = 117) chose to deliver vaginally, equally in both groups. Cesarean was more frequent for those who refused to fill in the questionnaires than for those who completed them (57% compared with 27%, P =.001). In the log-linear model, parous women who had conventional therapy and refused to fill in the questionnaires chose a cesarean more often than expected (standardized residual 2.54, P =.011). There were no differences between groups in satisfaction with childbirth or in puerperal depression.
                Both kinds of therapy reduced unnecessary cesareans, more so in nulliparous and well-motivated women. With intensive therapy, pregnancy- and birth-related anxiety and concerns were reduced, and labors were shorter. Latin America has a high rate of caesarean sections. We tested the hypothesis that a hospital policy of mandatory second opinion, based on the best existing scientific evidence, reduces the hospital caesarean section rate by 25%, without increasing maternal and perinatal morbidity and mortality.
                36 hospitals in Argentina (18), Brazil (eight), Cuba (four), Guatemala (two), and Mexico (four), were randomly assigned to intervention or control in a matched pair design. All physicians in the intervention hospitals deciding a non-emergency caesarean section had to follow a policy of mandatory second opinion. The primary outcome was the overall caesarean section rate in the hospitals after a 6-month implementation period. We also assessed women's satisfaction with labour and delivery care and physicians'acceptance of the second opinion policy.
                A total of 34 hospitals attending 149?276 deliveries were randomised and completed the protocol. The mandatory second opinion policy was associated with a small but significant reduction in rates of caesarean section (relative rate reduction 7.3%; 95% CI 0.2-14.5), mostly in intrapartum sections (12.6%; 0.6-24.7). Other maternal and neonatal outcomes and women's perceptions and satisfaction with the process of care were similarly distributed between the groups.
                In hospitals applying this policy of second opinion, 22 intrapartum caesarean sections could be prevented per 1000 deliveries, without affecting maternal or perinatal morbidity, and without affecting mothers' satisfaction with the care process. In an attempt to lower cesarean section rates, a cesarean surveillance system and a selective trial of labor were introduced in a tertiary hospital in Taiwan.
                From 1997 to 2000, 2 physicians were appointed as consultants for the pre-cesarean surveillance, and a trial of labor after a cesarean section was employed concurrently. We organized a weekly departmental Cesarean Indication Conference on Mondays. Comparisons of the cesarean rates between 1993-96 and 1997-2000 were made using the chi-square test. Comparisons of the proportion of overall cesarean sections contributed by each indication for both 1993 and 2000 were also made by chi-square test.
                A comparison of the 4-year periods before and after 1997 showed that the total cesarean rate had decreased from 37.0 to 30.7% (p < 0.001), primary cesarean rate from 21.3 to 17.8% (p < 0.001), and repeat cesarean rate from 15.7 to 12.9% (p < 0.001). No uterine rupture occurred. Among the 54 indications for primary cesareans, compared between 1993 and 2000, the proportion rates for dystocia, fetal distress, preeclampsia, induction failure, gestational diabetes, and elderly primigravidahad decreased substantially.
                The efficient way to lower the repeat cesarean rate is trial of labor, and the way to reduce the number of primary cesareans is in practicing of the guidelines for various indications. The cesarean surveillance system can solidify these guidelines, leading to a lower cesarean rate and an avoidance of inappropriate indications. To assess the effectiveness of a joint-specialty society and health department statewide peer-review program to reduce cesarean rates.
                Forty-five of the 165 hospitals with active delivery services were reviewed between 1989 and 1993. Differences in total and repeat cesarean rates and vaginal birth after cesarean (VBAC) rates were compared by hospital review status using Student t tests and linear regression for the years before and after completion of the program.
                Reviewed hospitals reduced their total cesarean rate by 3% and repeat cesarean rate by 0.7%, and increased their VBAC rate by 14.6% compared with nonreviewed hospitals, for which the respective reduction in rates was 1%, 0.6%, and 12.7%. Statistically, there was no difference between reviewed and nonreviewed hospitals in terms of rate changes.
                This joint-specialty society and health department peer review had no apparent impact on cesarean rates. Maternal anxiety and stress are found to be predictors of adverse pregnancy outcomes, including low birth weight and prematurity.
                The aim of the study was to determine whether relaxation education in anxious pregnant Iranian women in their first pregnancy affects selected pregnancy outcomes, including birth weight, preterm birth, and surgical delivery rate.
                A total of 110 obstetrically and medically low-risk primigravid women in Iran with a high anxiety level demonstrated by Spielberger's State-Trait Anxiety Inventory were randomly assigned into experimental and control groups.
                In this randomized controlled trial, the experimental group received routine prenatal care along with 7-week applied relaxation training sessions, while the control group received only routine prenatal care. Anxiety and perceived stress were measured by pre-educational and post-educational intervention. Data related to pregnancy outcomes include birth weight, gestational age at birth, and type of delivery.
                Significant reductions in low birth weight, cesarean section, and/or instrumental extraction were found in the experimental group compared with the control group. No significant differences were found in the rate of preterm birth.
                The findings suggest beneficial effects of nurse-led relaxation education sessions during the prenatal period. This intervention could serve as a resource for improving pregnancy outcomes in women with high anxiety. Decision-making about mode of birth after a cesarean delivery presents challenges to women and their caregivers and requires a balance of risks and benefits according to individual circumstances. The study objective was to determine whether a decision-aid for women who have experienced previous cesarean birth facilitates informed decision-making about birth options during a subsequent pregnancy.
                A prospective multicenter randomized controlled trial of 227 pregnant women was conducted within 3 prenatal clinics and 3 private obstetric practices in New South Wales, Australia. Women with 1 previous cesarean section and medically eligible for trial of vaginal birth were recruited at 12 to 18 weeks' gestation; 115 were randomized to the intervention group and 112 to the control group. A decision-aid booklet describing risks and benefits of elective repeat cesarean section and trial of labor was given to intervention group women at 28 weeks' gestation. Main outcome measures included level of knowledge, decisional conflict score, women's preference for mode of birth, and recorded mode of birth.
                Women who received the decision-aid demonstrated a significantly greater increase in mean knowledge scores than the control group (increasing by 2.17 vs 0.42 points on a 15-point scale) (p < 0.001, 95% CI for difference = 1.15-2.35). The intervention group demonstrated a reduction in decisional conflict score (p < 0.05). The decision-aid did not significantly affect the rate of uptake of trial of labor or elective repeat cesarean section. Preferences expressed at 36 weeks were not consistent with actual birth outcomes for many women.
                A decision-aid for women facing choices about birth after cesarean section is effective in improving knowledge and reducing decisional conflict. However, little evidence suggested that this process led to an informed choice. Strategies are required to better equip organizations and practitioners to empower women so that they can translate informed preferences into practice. Further work needs to examine ways to enhance women's power in decision-making within the doctor-patient relationship. During 1994, our department adopted several strategies in an attempt to decrease our cesarean delivery rates. This study evaluates the effect of these changes on our cesarean delivery rates.
                We studied data of women who delivered at our community hospital obstetric unit over a period of 6 years, from January 1, 1991, to December 31, 1996. During 1994, our department adopted labor management and cesarean delivery guidelines, with review of every cesarean delivery that did not meet guidelines and confidential individual feedback; established 24-hour in-house coverage; and attempted to achieve the goal of an annual cesarean delivery rate of less than 15%. These data were evaluated by chi2 analysis. Women who delivered in the first 3 years (group A) were compared with those who delivered in the second 3 years (group B) (ie, when the changes occurred). P < .05 was considered significant.
                Groups A and B shared similar demographic characteristics. The total cesarean delivery rate decreased from 22.5% (group A) to 18.6% (group B) (P = .001), whereas the primary cesarean delivery rate decreased from 13.5% to 10.6% (P = .001) and the repeat cesarean delivery rate decreased from 9.0% to 7.9% (P = .03). The proportion of women who received oxytocin and regional anesthesia and underwent vacuum-assisted deliveries increased (P < .001), whereas perinatal mortality and morbidity did not change.
                The cesarean delivery rate safely decreased. These data suggest the importance of the commitment of attending physicians to a lower cesarean delivery rate, of service improvements, and of detailed feedback. This study was carried out to evaluate the impact of birth preparation courses on the health of the mother and the newborn. A randomized clinical trial study was carried out on 200 primigravid women younger than age 35 years with gestational age of 20 weeks. Subjects were randomly divided into two groups: control and trial. Birth preparation classes were introduced to the trial group in eight sessions during pregnancy, whereas the control group received only routine care. Measurable clinical, obstetrical, and neonatal advantages were monitored and compared in two groups. Patients in the trial group suffered from back and pelvic pain and headache significantly less often than patients in control group (two-tailed p(2) < 0.05). Preparation is significantly related to reduction in dystocic deliveries and cesarean section ( p(2) = 0.044). Antenatal preparation could play a major role in the health of mother and newborn during labor and postpartum. In addition, antenatal preparation should be introduced to all women during pregnancy as a national health policy in Iran. nan Evaluating complex interventions in health services faces various difficulties, such as making practice changes and costs. Ways to increase research capacity and decrease costs include making research an integral part of health services and using routine data to judge outcomes. The purpose of this article is to report the feasibility of a pilot trial relying solely on routinely collected register data and being based on ordinary health services.
                The example intervention was education to public health nurses (PHN) (childbirth classes) to reduce caesarean section rates via pre-delivery considerations of pregnant women. 20 maternity health centers (MHC) were paired and of each 10 pairs, one MHC was randomly allocated to an intervention group and the other to a control; 8 pairs with successful intervention were used in the analyses (1601 mothers). The women visiting to the study maternity centers were identified from the Customer Register of Helsinki City. A list of the study women was made using the mother's personal identification number, visit date, the maternity center code, birth date and gestation length. The mode of delivery and health outcomes were retrieved from the Finnish Medical Birth Register (MBR). Process data of the intervention are based on observations, written feedback and questionnaires from PHNs, and project correspondence.
                It took almost two years to establish how to obtain permissions and to actually obtain it for the trial. Obtaining permissions for the customer and outcome data and register linkages was unproblematic and the cluster randomization provided comparable groups. The intervention did not succeed well. Had the main aim of the trial been to cause a change in PHNs behavior, we would have very likely intensified the intervention during the trial.
                Our experiences encourage the use of trials that obtain their outcomes from registers. Changing the behavior of ordinary health service providers is a challenging intervention.
                not registered (see Results). To test the hypothesis that cesarean sections are less likely to be performed after equalizing the fees for vaginal births and cesarean sections.
                Population-based National Health Insurance inpatient claims in Taiwan are used. Pre-periods and post-periods are identified to investigate the impact of the policy changes. Logistic regressions are employed.
                The cesarean section rates for the first, second and higher-order births are 29, 37.4 and 39.3%, while the primary cesarean section rates are 29, 11.8 and 12.1%, respectively. After taking into consideration the case-mix and birth order, the second and higher-order births were approximately 60% less likely to be cesarean deliveries compared to the first births and the increase in the VBAC fee had an additional negative effect on them. A fee equalization policy was not found to influence the cesarean delivery. The total cesarean section rate was primarily determined by the cesarean section rate for the first birth.
                Cesarean section rates are greater for the higher-order births because of the practice "once a cesarean section, always a cesarean section". Against the background of a rapidly declining fertility rate, females play a more important role in the mode of delivery than ever before. As such, financial incentives designed specifically for obstetricians do not have the desired impact. Policies that are aimed at altering behavior should be designed within the social context. The project "Obstetric Peer Review Interventions" (Verloskundige Onderlinge Kwaliteitsspiegeling Interventies, VOKSINT) was set-up in The Netherlands in 1994. It provided annual comparison data (quality ranking, league tables) for secondary care obstetric departments adjusted for population differences, based on the data registered in the Perinatal Database of The Netherlands (Landelijke Verloskunde Registratie, LVR). The aim of the so-called VOKS reports was to influence obstetricians' interventions in such a way that they led to a more homogeneous policy. To assess this influence, a trial was set-up, with departments randomly assigned to be or not to be informed about the VOKS results. Obstetric intervention rates and the morbidity of newborns including neonatal neurological examinations (NNEs) were assessed. Obstetric intervention rates were similar in the report group and the control group. Practice in the report group became more homogeneous (adjusted for population differences) than in the control departments, but this was only statistically significant for term caesarean section. A randomized controlled trial with 76 physicians in 16 community hospitals evaluated audit and feedback and local opinion leader education as methods of encouraging compliance with a guideline for the management of women with a previous cesarean section. The guideline recommended clinical actions to increase trial of labor and vaginal birth rates. Charts for all 3552 cases in the study groups were audited. After 24 months the trial of labor and vaginal birth rates in the audit and feedback group were no different from those in the control group, but rates were 46% and 85% higher, respectively, among physicians educated by an opinion leader. Duration of hospital stay was lower in the opinion leader education group than in the other two groups. The overall cesarean section rate was reduced only in the opinion leader education group. There were no adverse clinical outcomes attributable to the interventions. The use of opinion leaders improved the quality of care. To determine the effects of two computer based decision aids on decisional conflict and mode of delivery among pregnant women with a previous caesarean section.
                Randomised trial, conducted from May 2004 to August 2006.
                Four maternity units in south west England, and Scotland.
                742 pregnant women with one previous lower segment caesarean section and delivery expected at >or=37 weeks. Non-English speakers were excluded.
                Usual care: standard care given by obstetric and midwifery staff. Information programme: women navigated through descriptions and probabilities of clinical outcomes for mother and baby associated with planned vaginal birth, elective caesarean section, and emergency caesarean section. Decision analysis: mode of delivery was recommended based on utility assessments performed by the woman combined with probabilities of clinical outcomes within a concealed decision tree. Both interventions were delivered via a laptop computer after brief instructions from a researcher.
                Total score on decisional conflict scale, and mode of delivery.
                Women in the information programme (adjusted difference -6.2, 95% confidence interval -8.7 to -3.7) and the decision analysis (-4.0, -6.5 to -1.5) groups had reduced decisional conflict compared with women in the usual care group. The rate of vaginal birth was higher for women in the decision analysis group compared with the usual care group (37% v 30%, adjusted odds ratio 1.42, 0.94 to 2.14), but the rates were similar in the information programme and usual care groups.
                Decision aids can help women who have had a previous caesarean section to decide on mode of delivery in a subsequent pregnancy. The decision analysis approach might substantially affect national rates of caesarean section. Trial Registration Current Controlled Trials ISRCTN84367722. Our objective was to assess whether, for women with previous cesarean section, a prenatal education and support program promoting vaginal birth after cesarean delivery increases the probability of vaginal delivery.
                Women with a single previous cesarean were recruited before 28 weeks' gestation. Women's self-assessed motivation to attempt vaginal birth after a previous cesarean delivery was measured on a 10 cm visual analog scale: stratum I, low motivation; stratum II, high motivation. Women were randomized by stratum to one of two groups. Those in the "Verbal" group participated in an individualized education program. Those in the "Document" group were provided with a pamphlet detailing the benefits of planned vaginal birth after cesarean delivery.
                Rates of vaginal birth after cesarean section were similar in the verbal and document groups: verbal, 339 of 641 (53%); document, 310 of 634 (49%); relative risk 1.1, 95% confidence interval 1.0 to 1.2. There was no evidence of heterogeneity across motivational strata. Regardless of treatment group, women with low motivation for vaginal birth after cesarean section were more than three times as likely to undergo elective repeat cesarean than were women with high motivation (47% vs 13%).
                There was no evidence that an individualized prenatal education and support program, when offered to all women with previous cesarean delivery, results in a clinically significant increase in the rate of vaginal birth after cesarean section. Florida legislation implemented in the fall of 1992, unique in the nation, mandated that practice guidelines regarding cesarean section deliveries be disseminated to obstetric physicians. The law also required that peer review boards at hospitals be established to review cesarean deliveries and that the exact dates of implementation of the guidelines be reported to a state agency. To determine the impact of the legislation, we conducted a retrospective analysis of 366,246 total live births occurring in Florida hospitals during 1992 and 1993, before and after formal hospital certification of the implementation of the guidelines. Changes in primary and repeat cesarean rates were analyzed for 108 independent groups of births, controlling for the mother's age, race, payment source, and the timing of the implementation of the guidelines at hospitals. The guideline certification program did not accelerate the consistent but gradual downward trend in cesarean births which had already been evident in the three prior years. The data do suggest that the guideline program may have affected repeat cesareans more than primary cesareans, especially in the first quarter of 1993, immediately after the hospital certification period. Reductions in repeat cesareans involved both Medicaid and commercially insured births, whereas reductions in primary cesareans were found almost exclusively within commercially insured mothers, where the existing rates are highest. Although births with a prior cesarean represent only 12.5% of all births, significant decreases in repeat cesareans were found in groups representing 72.6% of this population. By comparison, significant decreases in primary cesareans were found in groups representing only 36.5% of the births without a prior cesarean. The date of guideline implementation reported by hospitals was not related to any systematic change in observed cesarean section rates. We concluded that the mere dissemination of practice guidelines by a state agency may not achieve either the magnitude or the specificity of the results desired without an explicit and thorough guideline implementation program. Blunt legislative mandates may be ineffective when multiple initiatives are already achieving desired outcomes.
Implementation of guidelines with mandatory second opinion can lead to a small reduction in caesarean section rates, predominately in intrapartum sections. Peer review, including pre-caesarean consultation, mandatory secondary opinion and postcaesarean surveillance can lead to a reduction in repeat caesarean section rates. Guidelines disseminated with endorsement and support from local opinion leaders may increase the proportion of women with previous caesarean sections being offered a trial of labour in certain settings. Nurse-led relaxation classes and birth preparation classes may reduce caesarean section rates in low-risk pregnancies.
