Cesarean birth decision-to-delivery interval in sub-Saharan Africa: A systematic review and meta-analysis

Background: Globally, in 2017, 810 women died daily from pregnancy- or childbirth-related preventable complications. Of these deaths, 94% occurred in resource-poor countries, with the highest maternal and perinatal mortality occurring in sub-Saharan Africa (SSA). We conducted a systematic review and meta-analysis of studies on the decision-to-delivery interval (DDI) from the SSA to determine the mean DDI, establish the maternal and neonatal outcomes reported, and evaluate the obstacles to achieving the gold standard DDI of ≤30 minutes. Methods: We performed a systematic literature review and meta-analysis of eligible studies between January 1995 and December 2022, in seven databases and grey literature. Studies of any design were included if they reported obstetric emergencies delivered by cesarean birth and had information on the DDI. Three independent reviewers applied eligibility criteria, assessed the risk of bias, and extracted data. The authors performed meta-analysis of mean DDI on studies with adequate data. Results: Thirty-nine studies with 41 datasets (12,835 participants), qualified for inclusion. In these studies, only 6.34% of cesarean deliveries were performed in under 30 minutes. A meta-analysis of 27 datasets found an overall DDI mean of 2.81 hours (168.8 minutes, 95%CI 151.5 to 186.2)). The pooled perinatal and maternal case fatality rates for the included studies were 61.2 in 1000 and 444.1 in 100,000 CDs, respectively. Conclusion: This review and meta-analysis found unacceptably high mean DDI, and perinatal and maternal mortality following cesarean delivery in SSA.

Decision to delivery interval, maternal and fetal outcomes in emergency caesarean sections in a tertiary teaching hospital, Dar es salaam, Tanzania.

Emergency caesarean section (CS) answers the question on how soon the procedure should be performed. Maternal and fetal outcomes deteriorate when decision to delivery interval (DDI) exceeds 75 min. This study aimed at determining the DDI, Maternal and fetal outcomes in CS categories at Muhimbili National Hospital (MNH). A descriptive cross-sectional study involving 427 emergency CS at MNH was conducted from September to November, 2017. Data was extracted and analysed using SPSS version 23.0 where frequency, means, chi-square test and DDI were calculated to determine its association with categories of CS. The mean DDI for category one, two and three CS were 126.73, 133.57 and 160.08 min respectively. Only two (0.5%) and 54 (12.6%) of category one and two emergency CS met the recommended DDI of 30 and 75 min respectively. Maternal and fetal adverse outcome were increasing with increase in DDI. There was no significant association between DDI and adverse maternal outcome (OR: 1.2; 95% CI 0.49-2.83) and fetal outcome (OR: 1.7; 95% CI 0.91-3.38). The proportions of adverse maternal and fetal outcome were high when DDI was ≥ 75 min. Improving triage of the patients according to their urgency is crucial in reducing prolonged DDI.

Determinants of the decision-to-delivery interval and the effect on perinatal outcome after emergency caesarean delivery: a cross-sectional study.

Preventing prolongation of the decision-to-delivery interval (DDI) for emergency caesarean delivery (CD) remains central to improving perinatal health. This study evaluated the effects of the DDI on perinatal outcome following emergency CD. A prospective cross-sectional study involving 205 consenting women who had emergency CD at a tertiary hospital in Nigeria was conducted. The time-motion documentation of events from decision to delivery was documented; the outcome measures were perinatal morbidity (neonatal resuscitation, 5-minute Apgar score, neonatal intensive admission) and mortality. Data analysis was performed with IBM SPSS Statistics version 20.0, and P<0.05 was considered significant. The overall mean DDI was 233.99±132.61 minutes (range 44-725 minutes); the mean DDI was shortest for cord prolapse (86.25±86.25 minutes) and was shorter for booked participants compared with unbooked participants (207.19±13.88 minutes vs 249.25±12.05 minutes; P=0.030) and for general anaesthesia compared with spinal anaesthesia (219.48±128.60 minutes vs 236.19±133.42 minutes; P=0.543). All neonatal parameters were significantly worse for unbooked women compared with booked women, including perinatal mortality (10.8% vs 1.3%; P=0.012). Neonatal morbidity increased with DDI for clinical indications, UK National Institute of Health and Care Excellence (NICE) and Robson classification for CDs; perinatal mortality was 73.2 per 1000 live births, all were category 1 CDs and all except one occurred with DDI greater than 90 minutes. Severe preeclampsia/eclampsia, obstructed labour and placenta praevia tolerated DDI greater than 90 minutes compared with abruptio placentae and umbilical cord prolapse. However, logistic regression showed no statistical correlation between the DDI and neonatal outcomes. Perinatal morbidity and mortality increased with DDI relative to the clinical urgency but perinatal deaths were increased with DDI greater than 90 minutes. For no category of emergency CD should the DDI exceed 90 minutes, while patient and institutional factors should be addressed to reduce the DDI.

Association and Determinants of Decision-Delivery Interval of Emergency Caesarean Sections and Perinatal Outcome in a Tertiary Institution

Introduction: A Decision to Delivery Interval (DDI) of 30 minutes for emergency caesarean section has been widely recommended but there is little evidence to support it. This target may not be practicable in a busy maternity unity and therefore, the anticipated beneficial effect on neonatal outcome requires re-evaluation. Aim: To determine the association between decision-delivery interval and perinatal outcome of emergency caesarean section at Alex Ekwueme Federal University Teaching Hospital, Abakaliki (AEFUTHA) over a period of four years. Materials and Methods: This was a retrospective observational study of the cases in emergency caesarean sections performed at the Department of Obstetrics and Gynaecology, AEFUTHA from 1st January 2012 to 1st January 2016. Hospital records of the women with singleton pregnancy at term who delivered through emergency caesarean sections were retrieved. Data extracted include socio-demographic and obstetric characteristics, duration between decision for caesarean section and intervention, indications for the caesarean section, reasons for delay in DDI, association between booking status and DDI and association of DDI and foetal outcome, APGAR score at 1st and 5th minutes and admission to NICU. Data were analysed with IBM statistics version 20. The p-value &lt;0.05 were regarded as statistically significant. Results: A total of 638 emergency caesarean sections involving singleton pregnancies at term, 522 (81.8%) of which had complete records and were analysed. The mean age of participants was 27.8±5.1 years, 89.3% were para 1-4 and 55.0% were unbooked. Only 6 (1.1%) of the emergency caesarean sections were performed within the recommended 30 minutes of DDI. The mean DDI was 189±124 minutes with range of 25 minutes to 1220 minutes. Two cases performed within 25 minutes were cases of foetal distress and cord prolapse while only a case of reduced foetal movement was delayed to 1220 minutes. The most common indications for emergency caesarean section were cephalopelvic disproportion 129 (24.7%) and foetal distress 65 (12.5%). The major cause of delay was delay in cross-matching of blood for surgery 136 (26.1%) while delay in giving informed consent contributed 67 (12.8%). There was no correlation between DDI of 75 minutes or above and the 1st minute APGAR score (AOR=2.48, CI=0.86-7.16, p-value=0.09), 5th minute APGAR score (AOR=3.08, CI=1.55-6.11, p-value=0.09), foetal outcome (AOR=0.82, CI=017-3.79, p-value=0.08) and admission to Newborn Intensive Care Unit (NICU) (AOR=2.08, CI=0.77-5.56, p-value=0.14). Conclusion: This study showed that there was no correlation between DDI&gt;75 minutes and poor perinatal outcome. Efforts should be made to strengthen the health system and improve the quality of care in order to keep DDI within this time limit for improved perinatal health outcome and indices.

Determinants of Decision to Delivery Interval (DDI) in Emergency Caesarean Sections in Ladoke Akintola University of Technology Teaching Hospital Ogbomoso, Nigeria

Background: Emergency caesarean sections are invaluable when vaginal delivery is either impossible or possess risk to the life of mother and or the foetus. Patients however still encounter delays after the decision has been made, despite recommended time frame. Objective: This is to identify the common indications for emergency caesarean section, factors responsible for delays after decision has been made and the short-term effect on the mother and neonate. Materials and methods: This was a retrospective study in which case records of patients who had emergency caesarean section were retrieved. Information about sociodemographic characteristics, booking status, parity, indication for surgery, decision time, incision time and short term feto-maternal outcomes were collected with the aid of structured proforma. Data was analyzed with Stata: Release 13 statistical software. Results: The mean age of participants was 28.9 ± 5.1 years, 51.3% were booked, primary caesarean section rate was 84.0%. The commonest indication was cephalo-pelvic disproportion (40.5%). The mean DDI was 145.3 ± 69.2 min. Patients’ factor was the leading cause of delay due to lack of funds and non-provision of surgical materials (53.5%). Leading hospital factors were non-availability of blood and blood products (32.8%) and power outage (28.0%). Five min APGAR score was normal in 92.3% of the neonates and 0.5% had severe asphyxia. Conclusion: This study shows that there are still avoidable delays in emergency caesarean section. Although there were no immediate neonatal complications, improving health care delivery so as to eliminate the identified causes would go a long way in reducing these delays.

The decision to delivery interval in emergency caesarean sections: Impact of anaesthetic technique and work shift.

Background: One important task of the emergency anaesthesia service is to provide rapid, safe and effective anaesthesia for emergency caesarean sections (ECS). A Decision to Delivery Interval (DDI) <30 minutes for ECS is a quality indicator for this service. The aim of this study was to assess the DDI and the impact of chosen anaesthetic technique (general anaesthesia (GA), spinal anaesthesia (SPA) with opioid supplementation, or "top-up" of labour epidural analgesia (tEDA) with local anaesthesia and fentanyl mixture) and work shift for ECS at Danderyds Hospital, Sweden. Methods: A retrospective chart review of ECS at Danderyds Hospital was performed between January and October 2016. Time between decision for CS, start of anaesthesia, time for incision and delivery, type of anaesthetic technique, and time of day, working hours or on call and day of week, Monday - Friday, and weekend was compiled and analysed. Time events are presented as mean ± standard deviation. Non-parametric tests were used. Results: In total, 135 ECS were analysed: 92% of the cases were delivered within 30 minutes and mean DDI for all cases was 17.3±8.1 minutes. GA shortened the DDI by 10 and 13 minutes compared to SPA and tEDA (p<0.0005). DDI for SPA and tEDA did not differ. There was no difference in DDI regarding time of day or weekday. Apgar <7 at 5' was more commonly seen in ECS having GA (11 out of 64) compared to SPA (2/30) and tEDA (1/41) (p<0.05). Conclusion: GA shortens the DDI for ECS, but the use of SPA as well as tEDA with opioid supplementation maintains a short DDI and should be considered when time allows. Top-up epidural did not prolong the DDI compared to SPA. The day of week or time of ECS had no influence on the anaesthesia service as measured by the DDI.

Peut-on diminuer le délai décision-extraction des césariennes en urgence en optimisant l’architecture des locaux ?

ObjectiveTo study the influence of architectural premises’ improvements on decision-to-delivery interval (DDI) in case of emergency cesarean sections. MethodsA retrospective observational Before-After study conducted in a type III maternity, first from 2004 to 2009 (Period 1, P1) then after moving our unit to new premises from 2009 to 2013 (P2). DDI, maternal and neonatal outcomes of every emergency cesarean section were studied. ResultsThe mean DDI of extremely urgent cesarean significantly decreased from 21.3±10.3minutes during P1 (n=294) to 14.9±7.14minutes during P2 (n=165). During P2 there was an increase in the proportion of extreme emergency cesarean sections done in less than 30minutes (85.1% versus 93.5%, P=0.003) as according to the ACOG recommendations, and also an increase of DDI of less than 15minutes (25.8% versus 61.1%, P<0.001). Also during P2 if there was a reduction of umbilical cord pHs, which were correlated to DDI, we observed a reduction of neonatal hospitalizations (42.2% versus 35.7%, P<0.001). Apgar score was correlated to umbilical cord pH and birth weight, but not to DDI. ConclusionThe space optimization has allowed our level III maternity to improve the rate of extreme emergency cesarean sections performed with DDI of less than 30 and even 15minutes, according to international recommendations. These results were obtained by reducing the transfer time to the operating room. Despite a positive correlation between DDI and umbilical cord pH, there was an improvement in neonatal outcomes associated with a decrease of neonatal hospitalizations.

Evaluation of decision-to-delivery interval in emergency cesarean section: A 1-year prospective audit in a tertiary care hospital.

Background and Aims:The American College of Obstetricians and Gynecologists (ACOG) committee on professional standards and the National Institute of Clinical Excellence (NICE) guidelines suggest that decision-to-delivery interval (DDI) and emergency cesarean section (CS) should not be more than 30 min, and a delay of more than75 min in the presence of maternal or fetal compromise can lead to poor outcome. This prospective 1-year study was conducted on emergency CS in a tertiary care hospital to evaluate the DDI, factors affecting it and to analyze their effects on maternal and neonatal outcome.Material and Methods:A structured proforma was used to analyze the data from all women undergoing emergency CS, during a 1-year period, included in Category 1 and 2 of NICE guidelines for CS.Results:A total of 453 emergency CSs were evaluated, with a mean DDI of 36.3 ± 17.2 min for Category 1 CS and 38.1 ± 17.7 min for Category 2 CS (P > 0.05). Only 42.4% emergency CSs confirmed to the 30 min DDI while 57.6% had a DDI of more than 30 min. Reasons of delay were identified as a delay in shifting the patient to operation theater (22.1%), anesthesia factors (18.1%), and lack of resources or manpower (16.1%). Maternal complications occurred in 15 (3.3%) patients with 3 (0.7%) nonsurvivors having a DDI of 91.0 ± 97.0 min as compared to survivors with a DDI of 36.8 ± 15.7 min, P = 0.001. There was no significant association between DDI and occurrence of neonatal complications.Conclusion:Failure to meet the current recommendations was associated with adverse maternal outcomes, but not with adverse neonatal outcome.

Implementation of the Four-Category Classification of Cesarean Section Urgency in Clinical Practice. A Prospective Study

Purpose: This study is aimed at investigating the clinical efficacy of the 4-category classification of urgent cesarean section. Methods: Women giving birth from September 2012 to December 2014 were prospectively investigated. Urgency C-section categories were color-coded: red - maternal/fetal life threat; yellow - maternal/fetal compromise, not life-threatening; and green - early delivery necessary. Results were audited. Results: A total of 4,754 women gave birth in the period considered, 1,313 (27.6%) with C-section of which 867 were urgent. The code was red in 0.98% of women, and 91.5% of newborns were delivered ≤30'; yellow in 5.1%; and green in 11.7%. The mean decision-to-delivery interval (DDI) ± SD was 19.6 ± 9.5 min, 36.6 ± 15.3 (p < 0.01), and 80.3 ± 52.8 (p < 0.01), respectively; and mean umbilical pH was 7.24 ± 0.10, 7.29 ± 0.08 (p < 0.05), and 7.33 ± 0.04 (p < 0.01) in the red, yellow, and green groups, respectively. Two (4.2%) red and 4 (2.2%) yellow newborns were acidotic. Mean DDI ± SD decreased from 21.7 ± 9.7 min in the period September 2012 to February 2013 to 17.4 ± 9.7 min in the period February to December 2014 (p = NS). Conclusions: Four-category classification led to achieving the target time in >90% of category 1 emergency C-sections, and stratified newborns with significantly different acidosis levels.

The Effect of a Program to Shorten the Decision-to-Delivery Interval for Emergent Cesarean Section on Maternal and Neonatal Outcome

Objective To study the effect of a departmental program designed to shorten the decision-to-delivery interval (DDI) for emergency cesarean section (ECS) for nonreassuring fetal heart rate (NRFHR) on maternal and neonatal outcome. Study Design A protocol for managing ECS that included documenting precise time-intervals, identification of delaying obstacles and debriefing of each case, was implemented from March 2011. All women who delivered by ECS for NRFHR, as the only indication were included. Detailed information regarding DDI, maternal intraoperative and postoperative complications, and neonatal early outcomes were compared before (period-P1) (−27 months) and after (period 2) (+27 months) program implementation. Results During 54 months of study, 593 ECS DDI were included. Mean DDI decreased at period 2 (12.3 ± 3.8 min, n = 301) compared with period 1 (21.7 ± 9.1 min, n = 292), P P = .016 and P = .031, respectively. Worse composite neonatal outcome decreased at period 2 compared with period 1, 15.6% vs 32.2%, respectively, P ≥ .001. Composite maternal outcome did not differ between the groups. Worse neonatal outcome was dependent on time period (period 1), odds ratio, 2.12; 95% confidence interval, 1.27–3.55; P = .004 and on gestational age at delivery, odds ratio, 0.68; 95% confidence interval, 0.62–0.76; P Conclusion Introduction of a management protocol to shorten DDI in ECS for NRFHR was associated with improved early neonatal outcome without change in maternal complications.

Five-year impact of a new departmental protocol on emergency cesarean target times

Objective: To evaluate the impact of an emergency cesarean standard operating procedure (SOP) on the decision-to-delivery interval (DDI) and to determine whether a shorter DDI improves neonatal outcome. Methods: Retrospective analysis of emergency cesareans from 2004 (introduction of the new SOP) to 2009 in a Swiss Level 3 perinatal center. Primary endpoints were the DDI, the pathology-to-decision interval (PDI), the 5 year learning curve, and neonatal and maternal outcome. Results: In the emergency cesarean group (175 women and 188 infants), mean DDI decreased over the observation period from 15 to 9 minutes (mean 10 minutes 41 seconds), and mean PDI from 11 to 6 minutes (mean 8 minutes). Not only did the DDI not exceed 15 minutes in over 90% of cases during the 5 years, but it fell consistently below 10 minutes in the latter stages of the learning curve. Only 2/188 infants had an umbilical artery pH

The decision-to-delivery interval in emergency Caesarean sections and its correlation with perinatal outcome: evidence from 204 deliveries in a developing country

The international standard decision-to-delivery interval (DDI) for emergency Caesarean sections (CSs) is ≤ 30 minutes but there is little evidence to support this recommendation. The aim of this study was to evaluate DDI for emergency CS and its relationship to perinatal outcome. We undertook a prospective observational study of consecutive cases of emergency CS. Perinatal outcomes were recorded as: Apgar score; neonates requiring admission; and perinatal deaths. The relation between DDI and perinatal outcome was analysed using chi-square and one way analysis of variance (ANOVA). Of 204 pregnancies observed, 19% of deliveries were achieved in ≤ 30 minutes. The mean DDI was 42.5 ± 19.4 minutes. There was no difference between the perinatal outcome for babies with DDI of ≤ 30 versus 31-60 minutes. There was a significantly higher risk of poor perinatal outcome for babies with DDI > 60 minutes. The perinatal outcome between DDI of ≤ 30 and 31-60 minutes was statistically not different. However, the ≤ 30 minutes DDI should remain the gold standard.

La mise en œuvre des codes « couleur » réduit le délai décision-naissance des césariennes urgentes

To assess the efficiency of a new tool designed to shorten the decision-to-delivery interval (DDI) for emergency C-sections (CS). DDI comparisons during three 6-month periods in a third level maternity. In stage A we evaluated the spontaneous DDI, in stage B the DDI was measured after the introduction of a color-code communication tool related to the degree of urgency for CS (amber code indicated urgent CS with an ideal DDI of 30 min and red code for very urgent CS with an ideal DDI of 15 min). In stage C we assessed the impact of the color-codes related protocols implementation. Two hundred and fifty-three C-sections were included (211 urgent CS and 42 very urgent CS). Mean DDI decreased significantly from 42 min to 24 min between period A and period C for amber codes (corresponding to 43.2% and 82.1% of the objectives respectively) and from 24.9 min to 10.7 min for red codes (20% et 83.3% of the objectives). This study suggests that color-codes and their related application protocols significantly shorten the DDI during the evaluation periods.

The Impact of a Trial of Instrumental Delivery in Theatre on Neonatal Outcome

The impact of a trial of instrumental delivery in theater on maternal and infant outcomes was examined in a prospective observational study of 229 consecutive deliveries utilizing ventouse (n = 134) or forceps (n = 95) because of either fetal distress or dystocia. All participants underwent instrumental delivery of a viable singleton pregnancy. The major outcome measures were the decision-to-delivery interval (DDI), mode of delivery, and the infant’s condition at birth. Sixty deliveries, just over one-fourth of the total, were managed as a trial in theater, 46 of them because of a prolonged second stage of labor (malposition being a factor in 39 instances) and 14 because of fetal distress. The mean DDI for these 60 deliveries was 59 minutes, compared with 21 minutes for 169 deliveries taking place in the labor room (P < 0.0001). All but one of these 169 deliveries took place within 45 minutes. One cesarean section was performed at 60 minutes. Nine women in all underwent cesarean delivery, 8 after a trial in theater. Malposition was a factor in 7 instances. Cord blood gas values were slightly less favorable when delivery followed a trial. These observations indicate that a trial of instrumental delivery takes 2 to 3 times longer than delivery in the labor room. Fetal malposition was the major indication for a trial of instrumental delivery and also the major reason for failed delivery. Based on recent guidelines from the Royal College of Obstetricians and Gynaecologists, at least 47% of labors in this study should have been managed as a trial in theater. The additional delay in delivery could be harmful to a fetus that already is hypoxic. The decision on whether or not to conduct a trial of instrumental delivery should be individualized.

Cohort study of the decision to delivery interval and neonatal outcome for emergency operative vaginal delivery

The purpose of this study was to assess whether a target decision to delivery interval (DDI) is appropriate for 'emergency' operative vaginal delivery and whether this would reduce adverse neonatal outcomes. We performed a retrospective cohort study of 1021 singleton term babies who experienced operative delivery for 'fetal distress' in the second stage of labor between 1998 and 2003 in Dundee, Scotland. The mean DDI in a labor room was 14.5 minutes (SD 9.5) compared to 30.0 minutes (SD 14.6) in an operating room. Shorter DDIs were associated with use of local rather than regional or general anesthesia. There were no significant differences in rates of low Apgar score (< 7 at 5 min) OR 0.99 (95% CI 0.27, 3.71), fetal acidosis (pH < 7.10) OR 1.24 (0.78, 1.99), neonatal resuscitation OR 1.00 (95% CI 0.65, 1.53), or admission to NICU OR 0.53 (95% CI 0.27, 1.03) for babies delivered within 15 minutes compared to greater than 15 minutes. The outcomes were similar for a 30-minute threshold. The DDIs for forceps and vacuum deliveries were similar as were neonatal outcomes. A DDI of 15 minutes is an achievable target for operative vaginal delivery in a labor room with 30 minutes for delivery in an operating room; however, setting arbitrary limits is unlikely in itself to prevent adverse neonatal outcomes.
