Slide 4-

Caesarean section as a mode of delivery Caesarean section is a surgical procedure that can effectively prevent maternal and newborn mortality when used for medically indicated reasons. There is no evidence showing the benefits of caesarean delivery for women or infants who do not require the procedure. As with any surgery, caesarean sections are associated with short and long term risk which can extend many years beyond the current delivery and affect the health of the woman, her child, and future pregnancies. These risks are higher in women with limited access to comprehensive obstetric care. Every effort should be made to provide caesarean sections to women in need, rather than striving to achieve a specific rate
Slide 5-

Caesarean section rates increasing worldwide The optimal caesarean section rate is unknown but it varies between facilities because of differences in the obstetric populations attended. Over the last decades birth by caesarean section has increased in a sustainable and continuous manner to unprecedented levels worldwide Governments and clinicians have expressed concern about the rise in the numbers of caesarean section births and the potential negative consequences for maternal and infant health.

Slide 6-

Non-clinical factors contributing to rising caesarean section rates Factors associated with caesarean births include: changes in the characteristics of the population such as increase of obesity, of multiple pregnancies, of nulliparous women or of older women. These changes are unlikely, however, to explain the large increases and wide variations in caesarean section rates across countries. Other non-clinical factors have all been implicated in this increase: women increasingly wanting to determine how and when their child is born generational shifts in work and family responsibilities physician factors increasing fear of medical litigation organizational, economic and social factors

SCOPE OF THE GUIDELINE The guideline recommendations relate to the use of CS in women with low-risk pregnancies, (specifically, healthy women with term, singleton, cephalic pregnancies), which represents majority of the obstetrical population. The guideline specifically considered those settings with high rates of caesarean section, where large numbers of caesareans are assumed to be unnecessary. Women with complications or particular obstetric risk factors (such as breech or multiple pregnancy) are not considered within the guideline. The guideline does not specify what clinical indications constitute a medically necessary CS, as the decision regarding medical necessity is according to the judgement of the treating clinician.

Primary audience of this guideline Target audience include: health-care professionals responsible for developing regional, national and local health protocols and policies obstetricians, midwives, nurses, general medical practitioners managers of maternal and child health programmes public health policy-makers

GUIDELINE DEVELOPMENT METHODS Development of a guideline proposal for the WHO Guidelines Review Committee Formation of technical groups Declaration and management of interests Formulating priority questions and outcomes Retrieval and synthesis of evidence Grading of the quality of the evidence Formulating the recommendations Planning for dissemination, implementation, evaluation and updating of the guideline A systematic evidence-based approach
Slide 11-

Technical groups involved in developing guideline WHO Steering Group This comprises staff members from the WHO Departments of Reproductive Health and Research (RHR); Maternal, Newborn, Child and Adolescent Health (MCA), who managed the guideline development process. Guideline Development Group This consists of external experts and stakeholders from the six WHO regions. Members were identified in a way that ensured geographic representation and gender balance, and they had no important conflicts of interest. The group examined and interpreted the evidence and formulated the final recommendations at a face-to-face meeting, September 2017. Technical Working Group This comprises guideline methodologists and systematic review team leads, who worked closely with WHO Steering Group to synthesize the evidence and other considerations for development of the recommendations. External Review Group These are external experts and stakeholders from the six WHO regions, who peer-reviewed the final guideline document to identify any factual errors and comment on clarity of the language, contextual issues and implications for implementation. External partners and observers Representatives of FIGO, ICM, RCOG, UNFPA and USAID

Priority guideline questions
Slide 14-

Priority guideline outcomes Critical outcomes Rate of caesarean section and rate of all other modes of delivery (spontaneous vaginal birth, caesarean section before labour, emergency caesarean section, instrumental vaginal birth) Perineal/vaginal trauma (e.g. vaginal tears, episiotomy) Birth trauma (e.g. fractured skull, haematoma, cerebral haemorrhage) Perinatal asphyxia (e.g. low Apgar score at 5 minutes, cord blood acidosis, needed major resuscitation) Maternal birth experience (e.g. maternal satisfaction with care) Important outcomes Maternal morbidity (e.g. peripartum infection, postpartum haemorrhage) Long-term infant outcomes (e.g. breastfeeding, childhood disability) Serious maternal morbidity (e.g. organ failure, obstetric hysterectomy, sepsis) Long-term maternal outcomes (e.g. urinary or faecal incontinence, obstetric fistula) Health-care resource utilization (e.g. length of hospital stay, maternal readmission/rehospitalization) Full PICO questions and outcomes are presented in the full guideline (Annex 1)

QUALITY ASSESSMENT AND SYNTHESIS OF THE EVIDENCE Confidence in the quantitative evidence was assessed using Grading of Recommendations Assessment, Development and Evaluation (GRADE) benefits and harms resource requirement cost-effectiveness Confidence in the qualitative evidence was assessed using Confidence in the Evidence from Reviews of Qualitative research (CERQual) values and preferences acceptability resource requirement equity feasibility GRADE Evidence-to-Decision (EtD) Framework was used to integrate evidence on benefits and harms of interventions, values, acceptability, resource use, equity, and feasibility.

Evidence base Systematic review of quantitative evidence Systematic reviews of qualitative evidence
Slide 17-

Systematic review of quantitative evidence Evidence on the effectiveness of interventions was derived from an updated Cochrane review of 29 studies: 19 randomised trials, 1 controlled before-after study and 9 interrupted time series studies. Most of the studies were conducted in high-income countries. None of the studies was done in a low-income country. The studies enrolled a mixed population of pregnant women, including nulliparous women, multiparous women, women with a fear of childbirth, women with high levels of anxiety and women having undergone a previous caesarean section.
Slide 18-

SYSTEMATIC REVIEWs OF QUALITATIVE EVIDENCE Judgements about values, acceptability, equity, resource implications and feasibility of interventions were informed by three systematic reviews of 49 qualitative studies.

FORMULATING RECOMMENDATIONS The Guideline Development Group (GDG) convened in September 2017 in Geneva, Switzerland, to review the summarized evidence and formulate recommendations. The GDG made three types of recommendations.

INTERVENTIONS TARGETED AT WOMEN When considering the educational interventions and support programmes, no specific format (e.g. pamphlet, videos, role play education) is recommended as more effective. (Low- to moderate-certainty evidence)

Implementation of the recommendations Barriers to implementation and strategies to address them
Slide 30-

IMPLEMENTATION OF THE RECOMMENDATIONS Community-level sensitization activities should be undertaken to disseminate information about the risks of unnecessary caesarean sections and the benefits of adhering to recommended practices. Lack of understanding of the value of recommended practices among women seeking maternity care, families or communities Barrier or constraint Implementation strategy Involve local opinion leaders; identify champions to promote the implementation of the recommendation. Involve training institutions and professional bodies in the introduction of the guideline so that pre-service and in-service training curricula can be updated with the recommendations. Resistance of health-care providers to changing their entrenched caesarean section practices; lack of understanding of the value of newly recommended interventions
Slide 31-

IMPLEMENTATION OF THE RECOMMENDATIONS Provide tailored patient education materials. Train targeted health-care professionals to provide patient education. Patients may make demands that hinder adherence Barrier or constraint Implementation strategy Organize teams in which roles are defined and they have a shared goal. Dysfunctional teamwork among health-care professionals (e.g. lack of communication between maternity and theatre staff). Lack of human resources with the necessary expertise and skills to implement, supervise and support recommended practices (e.g. senior clinicians to provide second opinion for caesarean section indication) Redistribute health-care resources; task shifting. Pragmatic consideration of what is feasible; gradual change; shifting resources from elsewhere in the health-care budget; increasing the health-care budget. Strategic long-term planning and budgeting to provide the necessary resources.
Slide 32-

IMPLEMENTATION OF THE RECOMMENDATIONS Adapt implementation strategies to work within the constraints of the existing systems. Strategic long-term planning and budgeting to provide the necessary resources. Lack of physical space (e.g. a venue for birth preparation classes and counselling sessions, training workshops) Barrier or constraint Implementation strategy Devise strategies to improve supply chain management according to local requirements, such as developing protocols for obtaining and maintaining the stock of supplies. Adapt implementation strategies to work within the constraints of the existing systems. Lack of essential supplies (locally adapted information, education and communication materials to support training, and support programmes, e.g. booklets or pamphlets in local languages) Lack of health information management systems designed to document and monitor recommended practices (e.g. electronic records, registers) Provide appropriate incentives to record the needed information. Strategic long-term planning and budgeting to provide the necessary resources for health information management systems.
Slide 33-

RESEARCH PRIORITIES The Technical Working Group and Steering Group identified areas where further studies are needed based on four broad considerations: uncertainty in the effects of the interventions due to evidence of very low or low certainty. concerns with the applicability of the evidence (particularly as most interventions were assessed in single studies; the interventions would benefit from replication in other settings). lack of studies for predefined guideline questions. promising interventions not specifically designed to reduce caesarean births that would benefit from examination in areas with high caesarean section rates (e.g. continuous one-to-one intrapartum support).
Slide 34-

RESEARCH PRIORITIES Future research should focus on the following areas In particular, the guideline development group emphasized that future intervention trials should be preceded with formative research to define locally relevant determinants of caesarean births.
