Associations between fetal position at delivery and duration of active phase of labor: A historical cohort study.

In clinical experience, occiput posterior (OP) position is associated with longer labor duration than occiput anterior (OA) position, but few studies have investigated the association between labor duration and fetal position. We aimed to compare duration of the active phase of labor in OP deliveries with OA deliveries in a contemporary population using survival methods. Secondary aims were to compare the frequencies of operative interventions, obstetric anal sphincter injuries (OASIS), postpartum hemorrhage, and newborn outcomes in OP with OA deliveries. We did a historical cohort study in three university hospitals in Norway from 2012 to 2022. Women with a single fetus in cephalic presentation, no previous cesarean section and gestational age ≥37 weeks were eligible and stratified into the first four groups of the Robson ten-group classification system (TGCS). We estimated the mean duration and calculated the hazard ratio (HR) for delivery using survival analyses. Cesarean sections and instrumental vaginal deliveries were censored. The study population comprised 112 019 women, 105 571 (94.2%) were delivered in OA and 6448 (5.8%) in OP position. The estimated mean duration of the active phase of labor was longer in women with the fetus in OP position in all four TGCS groups. The estimated duration was longer in the OP groups in analyses stratified with respect to epidural analgesia and oxytocin augmentation. The graphical abstract illustrates the probability of delivery in OP compared with OA position in merged TGCS groups 1 and 2a, as a function of time. The unadjusted HR was 0.33 (95% CI 0.31-0.36) for fetuses delivered in OP position compared with OA position in TGCS group 1, 0.25 (95% CI 0.21-0.27) in group 2a, 0.70 (95% CI 0.67-0.73) in group 3, and 0.61 (95% CI 0.55-0.67) in group 4a, respectively. Neither maternal age, gestational age, BMI nor birthweight had confounding effect. Operative delivery rates and OASIS rates were higher in OP position in all four groups. We found longer duration of the active phase of labor in women with the fetus delivered in OP position in all four TGCS groups.

Stillbirth mortality by Robson ten-group classification system: A cross-sectional registry of 80 663 births from 16 hospital in sub-Saharan Africa.

To assess stillbirth mortality by Robson ten-group classification and the usefulness of this approach for understanding trends. Cross-sectional study. Prospectively collected perinatal e-registry data from 16 hospitals in Benin, Malawi, Tanzania and Uganda. All women aged 13-49 years who gave birth to a live or stillborn baby weighting >1000 g between July 2021 and December 2022. We compared stillbirth risk by Robson ten-group classification, and across countries, and calculated proportional contributions to mortality. Stillbirth mortality, defined as antepartum and intrapartum stillbirths. We included 80 663 babies born to 78 085 women; 3107 were stillborn. Stillbirth mortality by country were: 7.3% (Benin), 1.9% (Malawi), 1.6% (Tanzania) and 4.9% (Uganda). The largest contributor to stillbirths was Robson group 10 (preterm birth, 28.2%) followed by Robson group 3 (multipara with cephalic term singleton in spontaneous labour, 25.0%). The risk of dying was highest in births complicated by malpresentations, such as nullipara breech (11.0%), multipara breech (16.7%) and transverse/oblique lie (17.9%). Our findings indicate that group 10 (preterm birth) and group 3 (multipara with cephalic term singleton in spontaneous labour) each contribute to a quarter of stillbirth mortality. High mortality risk was observed in births complicated by malpresentation, such as transverse lie or breech. The high mortality share of group 3 is unexpected, demanding case-by-case investigation. The high mortality rate observed for Robson groups 6-10 hints for a need to intensify actions to improve labour management, and the categorisation may support the regular review of labour progress.

Analysis of caesarean delivery rates using Robson ten group classification system in North West Amhara referral hospitals, Ethiopia, 2022: A cross-sectional study

IntroductionThe cesarean delivery rate has been consistently rising over time and differs among different hospitals. In order to understand the specific factors contributing to this rapid increase beyond the recommended levels, it is necessary to continuously monitor and evaluate cesarean deliveries using the Robson ten-group classification system. Consequently, the objective of this study was to evaluate the rate of cesarean deliveries within each group by employing the Robson ten-group classification system. MethodA cross-sectional study design was conducted in referral hospitals in the North West Amhara region, involving 721 mothers who gave birth between January and February 2022. Participants were selected using systematic random sampling. Data collection involved an interviewer-administered, pretested, semi-structured questionnaire, as well as a review of medical charts. The women were allocated into one of the ten Robson groups. The proportion of each group, the contribution of each group to the total caesarean delivery rate, and the caesarean delivery rate within each group were all calculated. ResultThe overall caesarean delivery rate was 277 (38.3 %). The primary factors contributing to the overall cesarean delivery rate were found to be group 1 (23.9 %), group 5 (21 %), group 3 (11.6 %), and group 10 (11%). The most common indication for caesarean delivery included an abnormal fetal heart rate pattern, the presence of meconium in the amniotic fluid, a history of previous cesarean delivery, fetal-pelvic disproportion, and breech presentation. ConclusionGroup 1, 5, 3, and 10 emerged as the major contributor to the overall cesarean delivery rate. Interestingly, this study also unveiled a significant prevalence of cesarean delivery among low-risk groups. These specific groups warrant further investigation to identify potential factors that can be modified and implement targeted interventions to decrease the cesarean delivery rate. It is crucial to evaluate existing management protocols in the study area.

Errors in the classification of pregnant women according to Robson ten-group classification system

ObjectivesThe Robson Ten-Group Classification System (TGCS) is widely used as a classification system for perinatal analyses such as Caesarean section (CS) rates. In Germany, standardised data sets on deliveries are classified by quality assurance institutions using the TGCS. This observational study aims to evaluate potential errors in the TCGS classification of deliveries. Study designManual TGCS classification of all 1370 deliveries in an obstetric unit in 2018 and comparison with semi-automatic TGCS classifications of the quality assurance institution. ResultsIn the manual classification, 259 out of 1370 births (18.9 %) were assigned to a different Robson group than in the semi-automatic classification. The proportions of births by Robson group were significantly different in TGCS group 1 (32.2 % vs. 37.6 %, p = 0.0034) and group 2 (18.4 % vs. 14.4 %, p = 0.0053). Concordance between manual and semi-automatic classifications ranged from 59.5 % in group 2 to 100.0 % in groups 6, 7, 8, and 9. The most frequent mismatches were for the parameters “onset of labour” in 184 cases (13.4 %), “parity” in 42 cases (3.1 %) and “previous uterine scars” in 23 cases (1.7 %). In the manual classification, there were significant differences in the CS rate in group 1 (7.9 % vs. 2.5 %, p < 0.0001), group 2 (30.2 % vs. 48.2 %, p < 0.0001), and group 4 (14.1 % vs. 37.4 %, p = 0.0004), compared to the semi-automatic classification. ConclusionsDue to incorrect data entry and unclear definitions of criteria, quality assurance data in obstetric databases may contain a relevant proportion of errors, which could influence statistics with TGCS in context of CS rates in international comparisons.

Trends in caesarean section rates in Europe from 2015-2019 using Robson's Ten-Group Classification System: A Euro-Peristat registry study

Abstract Objective To assess changes in caesarean section (CS) in Europe from 2015-2019 and utilise the Robson Ten Group Classification System (TGCS) to evaluate the contribution of different obstetric populations to overall CS rates and trends Methods This was an observational study utilising routine population birth data from 28 European countries participating in the Euro-Peristat network. We included all births ≥22 weeks gestational age, from 2015 to 2019. A federated model used individual-level data from routine sources in each country formatted to common data model to generate anonymous, aggregate data tables on yearly CS rates and the Robson TGCS classification. We computed the Robson group-specific relative size, CS rate, relative and absolute contribution to overall CS rate Results Among the 28 European countries, CS rates (2015: 16.0-55.9%; 2019: 16.0-52.2%) and trends varied (-3.7-+4.7%; 9 countries decreasing, 7 stable [ ≤ ±0.2], 12 increasing). Using the Robson Classification (17 countries), in most countries, labour induction increased (Groups 2a, 4a), while multiple pregnancies (Group 8) decreased. In countries with decreasing overall CS rates, CS tended to decrease in most Robson groups, while in countries with increasing overall CS rates, CS tended to increase in most Robson groups. In countries with the greatest increase in CS rates (&amp;gt;1%), absolute contributions of Groups 1 (nulliparous term cephalic singletons, spontaneous labour), 2a and 4a, 2b and 4b (prelabour CS), and 10 (preterm cephalic singletons) to overall CS tended to increase. Conclusions Analysis of the Robson Classification shows varying CS trends and rates across Europe. Comparisons between European countries, particularly those with divergent trends, could provide insight into strategies to reduce CS without indication.

Study of Caesarean Section Births in a Tertiary Care Hospital in Mumbai Using Robson Classification System.

Robson ten-group classification system is recommended by WHO (World health organization) as a global standard for assessment and monitoring caesarean section (CS) rates. This classification is simple and robust. It is prospective, easily reproducible and clinically relevant. We conducted a prospective observational study of CS births at a tertiary care institute. Caesarean births in a tertiary care hospital were classified using Robson classification system as recommended by WHO. The study was conducted for period of 6months duration. The ethics committee of the institute approved this study. We enrolled 4771 consecutive women who delivered during this study period. We included patients who had vaginal delivery as well as those who had delivery by CS. Both live births and stillbirths (of at least 500-g birth weight or at least 22weeks gestation (according to WHO recommendations) were included in this study. During this study period, we had 4771 deliveries, out of which 2231 pregnant women (46.76%) were delivered by CS as compared to 2540 vaginal deliveries. Women with previous CS (term with single cephalic pregnancy) were included in Robson group 5. Group 5 had the highest CS rate (13.41%). Robson group 5, 1 and 10 were the largest contributors to the high CS rates at our institute. In our study, 4771 deliveries were conducted during this study period (6months). Out of 4771 deliveries, CS was done in 2231 pregnant women (46.76%). 2540 women had vaginal deliveries. Group 5 (13.41%) which comprised of women with previous CS had the highest CS rate followed by group 1 and group 10. The second largest contribution was from Group 1 with CS rate of 9.01%. Robson Group 1 included nulliparous term women with single cephalic pregnancy in spontaneous labour. Group 10 was the third largest contributor to the overall CS. Group 10 included women who delivered preterm (single cephalic presentation). Group 10 contributed to 8.09% of overall CS rate. We should make every effort to provide CS for women requiring this procedure, rather than work towards achieving a specific rate for CS.

Auditing cesarean section indications in women of Groups 1 to 4 of Robson's Ten-Group Classification System: A descriptive study at a university hospital in Thailand

Aim: To determine the appropriateness of indication for cesarean section in women at term with a single fetus in cephalic presentation without previous CS irrespective of parity and how labor started (Robson's Ten-Group Classification System [RTGCS] groups 1-4). Methods: This was a descriptive study assessing medical records of 311 women in RTGCS groups 1- 4, between 1st January 2020 and 31st December 2020 who underwent a CS in Srinagarind Hospital, a university hospital, Khon Kaen, Thailand. Appropriateness of CS indications was assessed using criteria developed by our institute. Indications were classified into three categories: cephalopelvic disproportion (CPD), fetal indications, and other maternal indications. Results: The overall appropriate rate of CS indications in RTGCS groups 1-4 was 32.5% (95% CI 26.8% – 38.7%). The appropriate rates of CS indications in RTCGS group 1, 2a, 2b, 3, 4a, and 4b were 43.0% (95% CI 35.2% - 51.2%), 10.6% (95% CI 0.0% - 24.9%), 11.7% (95% CI 0.0% - 25.0%), 50.0% (95% CI 32.1% - 68.6%), 0% (95% CI 0.0% - 100%), and 40.0% (95% CI 20.0% - 74.8%) respectively. Conclusion: Low appropriateness in CS indications in RTGCS groups 1-4 leads to high CS rates. Increasing appropriateness of CS indications in this population will reduce unnecessary CS. Interventions focusing on increasing appropriateness in CS indications are urgently required to achieve appropriate use of CS.

Analysis of Cesarean Section Rates in a Public Tertiary Hospital During Teaching and Non-teaching Periods Using the Robson Ten Group Classification System.

The rising cesarean section (CS) rate is a global concern. One of the hospital characteristics that may explain the variation in CS among hospitals is hospital teaching status. This study aims to assess the rate of CS in a tertiary hospital during the teaching and non-teaching periods and to conduct an analysis using the Robson ten-group classification system. This study is a retrospective cohort that assessed pregnant mothers who gave birth at a tertiary hospital in Bandar Abbas. The study population was divided into two groups: those who gave birth during the hospital's teaching period (November 1st, 2019 to October 30th, 2020) and those who gave birth after that (November 1st, 2020 to October 30th, 2021). The primary outcome was the rate of CS according to Robson's classification system. The secondary outcome was the contributions of each group of Robson to the overall CS rate. Data were extracted by trained collectors from the "Iranian Maternal and Neonatal Network (IMaN Net)," a valid national system, using electronic patient records. Of the total number of births (8382), 62.9 % occurred during the teaching period and 37.1 % during the non-teaching period. A 7% increase in CS was observed during the teaching period of the hospital compared to the non-teaching period (p<0.01). CS rate in Robson groups 1,2,4,7, and 10 differs significantly between teaching and non-teaching periods. According to the findings, Groups 5, 10, and 2 were the three most significant contributors to overall CS in our hospital during the study period. The efforts to reduce the overall CS rate should be focused on groups 2,5, and 10 of Robson.

Comparing Cesarean Birth Utilization Between US Hospitals: A Demonstration of the Robson Ten-Group Classification System for Use in Quality Improvement and Benchmarking.

The World Health Organization-endorsed Robson Ten-Group Classification System (TGCS) is a standard reporting mechanism for cesarean birth, yet this approach is not widely adopted in the United States. To describe the application and utility of the TGCS to compare hospital-level cesarean births rates, for use in quality improvement and benchmarking. We conducted a descriptive, secondary data analysis of the Consortium on Safe Labor dataset using data from 228 438 women's births, from 2002 to 2008, in 12 sites across the United States. We stratified births into 10 mutually exclusive groups and calculated within-group proportions of group size and cesarean birth rates for between-hospital comparisons of cesarean birth, trial of labor after cesarean (TOLAC), and labor induction utilization. There is variation in use of cesarean birth, labor induction, and TOLAC across the 12 sites. The TGCS provides a method for between-hospital comparisons, particularly for revealing usage patterns of labor induction, TOLAC, and cesarean birth. Adoption of the TGCS in the United States would provide organizations and quality improvement leaders with an effective benchmarking tool to assist in reducing the use of cesarean birth and increasing the support of TOLAC.

Variables associated with the Robson Ten-Group Classification System in the State of São Paulo, Brazil

This study evaluated the associations between the groups of the Robson Classification System and maternal sociodemographic characteristics among neonates in São Paulo State, Brazil, 2016. The groups 5, 6, 7, 8 and 9 tend to be associated to cesarean delivery and more privileged educational opportunities, while the groups 1, 4 and 3 tend to be associated to vaginal delivery and less privileged educational opportunities. These results reinforce the notion that strategies for reduction of cesarean deliveries should go beyond a biomedical model focused on biological factors, and should also consider the social factors that characterize the living conditions of people.

COVID-19 and Cesarean Section Rates: A Retrospective Observational Study at Our Rural Tertiary Center using Robson's Classification

Objective: This study aimed to evaluate the effect of COVID-19 infection on the rate and indications for cesarean section (CS) according to Robson's Ten-Group Classification system. Methodology: Our study was a 6-month retrospective observational study at the Maternal and Child Health Wing where every antenatal woman who was admitted irrespective of gestational age and whether in labor or not was customarily screened for COVID-19 infection. Based on the mode of delivery, all delivered women were classified into two groups: vaginal or cesarean, and the information was then further classified according to Robson's classification. Data collected were analyzed using Excel sheets, and Chi-square test was applied to evaluate if the difference in CS rates was statistically significant. Results: During COVID months, a total number of confinements were 877, among which the cesarean section were 381, contributing to a rate of 43.4%. The total COVID-19-positive confinements during the same period were 68. Group 2 formed the vast majority of CSs, followed by Group 1 and 5. During the post-COVID months, summation of confinements was 1443, among which the CS were 580, thereby contributing to a rate of 40.1%. In contrast to COVID time, Group 5 formed the greatest chunk contributing to CS rate, followed by Group 2 and 1. There was a statistically significant difference among confinements during COVID and post-COVID period and between CS rates among COVID-19 positive and negative women. Conclusion: During the COVID pandemic, there was a decrease in the number of confinement in our hospital. However, the CS rate increased and according to Robson's classification Group 1 and 2 made greatest contribution to CSs due to changed dynamics.

Assessment Of Caesarean Section Rate Using Robson Ten Group Classification System In A Tertiary Care Hospital: A Cross Sectional Study.

The growing rate of caesarean section is a major concern for quality of maternal life and public health. Concerns about such increases prompted the WHO to recommend Robson ten group classification system for assessing the Caesarean Section rate. The present study's aim was to assess the caesarean rate using Robson's ten group classification system and highlighted the reliable information system, in turn, helps to construct interventions to reduce avoidable caesareans. This cross sectional study was carried out on 5796 women who delivered from 25th November 2021 to 24th November 2022 in Jinnah Post Graduate medical Centre Karachi. Data was collected from the women admitted for delivery using Robson's Pro forma. Relative size and caesarean rate of each group and overall caesarean section rate was calculated. Of the total 5796 deliveries, 2141 (36.9%) were caesarean deliveries and 3655 (63.1%) had normal deliveries. Out of Robson's ten groups system, Group 10 had a higher contribution of 705 (12.2%) to the overall caesarean rate followed by group 5 had 627 (10.8%). The contributing prevalence of Group 1, 2, 3, 4, 6, 7, 8 and 9 were 122 (2.1%), 317 (5.5%), 50 (0.87%), 167 (2.9%), 42 (0.72%), 35 (0.6%), 49 (0.85%) and 27 (0.46%) respectively. Our study concluded that Group 10 and 5 were the most responsible for the whole Caesarean Section rate. In all contributing groups, there is a need to identify the indications and to sub classify these groups further so that preventable caesarean sections can be avoided by reducing these factors.

Direct standardization method according to Robson classification for comparison of cesarean rates

BackgroundCompare cesarean section rates between populations or within a population over time using the crude measure is biased mainly due to differences in the characteristics of the obstetric population. The Robson Ten Group Classification (RTGC) is being widely used all over the world based on a few basic obstetrics variables.ObjectivesPropose a method of direct standardization according to RTGC to make the overall rates of cesarean sections comparable between different populations or within the same population over time.MethodsWe used data from the WHO Global Maternal and Perinatal Health Survey (WHOGS) conducted between 2004 and 2008 and data from the WHO Multinational Survey on Maternal and Neonatal Health (WHOMCS) conducted between 2010 and 2011, covering information from obstetric population of 21 countries. The standard population was based in the average size of Robson Groups in WHOMCS. The crude and standardized rates, their differences intra and inter populations, and its respective confidence intervals were calculated.ResultsThe impact and importance of the method were demonstrated. The five leading countries list on cesarean rates was completely modified and changes of cesarean rates over time in the same country varied in both directions by the standardization.ConclusionThis method is useful to compare overall rates as an additional information when RTGC Report Table is been used or, for some type of studies as analytical ecologic studies with multiple groups, where leading with the report tables are laborious and hard to interpret. The use of Robson Ten Group Classification for direct standardization of cesarean rates is easy to apply and interpret.

Cesarean delivery rates based on time and indication using the Robson Ten-Group Classification System: Assessment at a Turkish tertiary center.

This study aimed to evaluate increasing cesarean delivery (CD) rates, their causes, and changes over the years in a Turkish tertiary center using the Robson Ten-Group Classification System (RTGCS). Data of deliveries involving birth weight of ≥500 g or ≥24 weeks of gestation period from 2013 to 2020 were retrospectively collected and classified from the hospital digital record system using obstetric concepts and parameters described in the RTGCS. The overall CD rate for all births (69051) from 2013 to 2020 was 55.5%. Groups 3, 5, and 1 were the most represented groups (29.1%, 23.9%, and 19.4%, respectively). The major contributors to the overall CD rate were Groups 5, 2, and 10 (23.8%, 9.9%, and 5.6%, respectively). Groups 2 and 4 (nullipara, multipara, single cephalic at term) had high CD rates associated with high rates of pre-labor CD (88.9% and 73.3%, respectively). The CD rate was 99.7% in Group 5, which showed recurrent CD, and 67.2% in Group 10. The overall CD rate was 60.8% in 2020 owing to the significant increase in the contributions by Groups 5, 8, and 10. The most common indication for CD was previous CD (46.1%), fetal distress (13.2%), and cephalopelvic disproportion (CPD) (8%). Groups 1, 2, 5, and 10 were the major contributors to the overall CD rate at this tertiary center. To reduce overall CD rates, policies that reduce primary CD and support vaginal delivery after cesarean section should be established.

Robson's Ten Group Classification System to Evaluate Cesarean Section Rates in Honduras: The Relevance of Labor Induction.

To use the Robson Ten Group Classification (RTGC) to analyze cesarean section (CS) rates in a Honduran maternity hospital, with focus in groups that consider induction of labor. Cross-sectional study. Women admitted for childbirth (August 2017 to October 2018) were classified according to the RTGC. The CS rate for each group and the contribution to the overall CS rate was calculated, with further analyses of the induction of labor among term primiparous (group 2a), term multiparous (group 4a), and cases with one previous CS (group 5.1). A total of 4,356 women were considered, with an overall CS rate of 26.1%. Group 3 was the largest group, with 38.6% (1,682/4,356) of the cases, followed by Group 1, with 30.8% (1,342/4,356), and Group 5, with 10.3% (450/4,356). Considering the contribution to overall CS rates per group, Group 5 contributed with 30.4% (345/1,136) of the CSs and within this group, 286/345 (82.9%) had 1 previous CS, with a CS rate > 70%. Groups 1 and 3, with 26.6% (291/1,136) and 13.5% (153/1,136), respectively, were the second and third larger contributors to the CS rate. Groups 2a and 4a had high induction success, with low CS rates (18.4 and 16.9%, respectively). The RTGC is a useful tool to assess CS rates in different healthcare facilities. Groups 5, 1, and 3 were the main contributors to the CS rate, and groups 2 and 4 showed the impact and importance of induction of labor. These findings may support future interventions to reduce unnecessary CS, especially among primiparous and in women with previous CS.

Analysis Of Caesarean Sections Rates Using Robson's Ten Group Classification System, Unit B Mchc, Ath Abbottabad.

There is growing international concern about the increased rate of caesarean sections (CS), Caesarean procedures performed in the absence of a clinical justification do not reduce maternal or infant death rates if carried out at a rate higher than 10%-15% Achieving reductions in maternal and infant morbidity and mortality are, among others, the objectives promoted by the World Health Organization (WHO) for 2030. The analysis of unjustified C/S rate is done by Using Robson's Ten Group Classification system. Cross-sectional study by using Robson's Ten Group classification, in Unit B MCHC, ATH Abbottabad during 6 months, from 1st August 2021-31st January 2022. Total Patients Delivered during this duration of study were 777, among which 352 were delivered by C/S were 352. Analysis by Robson ten-group classification system showed C/S Rate as: Group 1:16.81%, Group 2: 78.95%, group 3:1.56%, group 4:77.14%, group 5:89.22%, group 6: 83.33, Group 7:67.86, Group 8:40, group 9:100%, Group 10:46.97. The total Caesarean section rate was 45.3%. By RTGCS analysis, C/S rates Group 5, 4 and 2 are major contributions in overall C/S rates in studied clinical setup. Group 1 and 10 are also contributing. Overall C/S rates can be decreased by working on them.

Achieving an appropriate cesarean birth (CB) rate and analyzing the changes using the Robson Ten-Group Classification System (TGCS): Lessons from a Tertiary Care Hospital in Italy.

To describe the interventions that were implemented at a Tertiary University Hospital and how they affected the rate of cesarean birth (CB) and main obstetrics and neonatal outcomes. An analysis of the contemporaneously collected data from all deliveries that occurred from 2014 to 2018. Major obstetric and neonatal outcomes were analyzed and grouped according to the Ten-Group Classification System (TGCS). A significant decrease in CB rates, from 28.4% to 23.0% (P<0.001), was found over the study period. Although the relative sizes of both nulliparous (groups 1+2) and multiparous (groups 3+4) women remained stable over the study period, a significantly higher incidence of CB was reported in 2014 for both groups, compared with 2018 (2.6% vs. 13.0%, P<0.001 for nulliparous women and 7.5% vs. 3.3%, P<0.001 for multiparous women). In contrast, the relative size of Group 5 was significantly lower in 2014 than in 2018 (9.9% vs. 11.5%, P=0.003), but a 13.3% reduction in CB was also reported for this group. No significant differences were noted in the occurrence of major obstetrics and neonatal outcomes that were reported. A reduction in CB rate may be safely achieved through implementing a multifaceted strategy.

Analysis of caesarean section rates according to Robson's ten group classification system at a tertiary care teaching hospital in South India

Background: Robson’s ten-group classification system (RTGCS) is recommended by WHO as an analytical tool for effective monitoring of caesarean section (CS) rates. The overall CS rates are high but seldom, women are classified based on CS.Methods: Data was collected and reviewed retrospectively. All the pregnant women who delivered from January 2016 to December 2017 in the labour ward were classified according to RTGCS.Results: Total of 2951 women delivered- 1598 (54.15%) vaginally and 1353 (45.84%through CS. In this study, Group 5 was the largest contributor (30.08%), group 1 was second (28.15%).Conclusion: Reviewing the definition of failure to progress in labour and changing norms of fetal distress may lower CS rates in groups 1, 2 and5. RTGCS proves to be an effective tool that allows standardized comparison of data, time point and identifies the groups responsible for rising CS rates.

Investigating Caesarean Section Practice among Teenage Romanian Mothers Using Modified Robson Ten Group Classification System.

The Robson ten-group classification system is a recognized effective method of assessing caesarean rate. It is based on dividing patients into ten mutually exclusive groups, focusing on six maternal and newborn variables (parity, gestational age, plurality, foetal presentation, previous caesarean, and mode of labour onset). The aim of our analysis was twofold: first, to present the implementation of Robson classification in a pregnant teenage population; and second, to identify the indications for CS in the adolescent population. This study was designed as a one-year prospective analysis and considered all women younger than 20 years of age who delivered in a tertiary care hospital. Before discharge, women who had caesarean delivery responded to a questionnaire regarding their education, prenatal surveillance, and obstetrical history. Caesarean sections accounted for 47.01% of all births. A proportion of 24.57% of the participants had at least one previous caesarean section. Group 10 (all women with a single cephalic preterm pregnancy) was second most often identified among women in middle adolescence (14.03%); 32.20% of the participants in late adolescence were in group 5 (multiparas with a scarred uterus, single cephalic term pregnancy). Differences between the two age groups were not statistically different (p = 0.96). Abnormal cardiotocographic findings (38.23%), the arrest of descent (19.11%) and arrest of dilation (19.11%), were the most frequent indications for caesareans in Robson group 1. Neonates from mothers in Robson groups 8 (women with a multiple pregnancy) and 7 (multiparas single breech pregnancy) had the most unfavourable outcomes regarding gestational age at delivery and admission to the intensive care unit. We concluded that future focus on obstetrical management is mandatory in Robson groups 7 and 8. Adolescents in Robson group 1 (nulliparas, single cephalic term pregnancy, spontaneous labour) are the primary beneficiaries of strategies to reduce caesarean sections rates.
