Introduction
Elective caesarean sections (CS), defined as planned surgical deliveries before the onset of labour, have become increasingly common in the UK, with rates rising from 10.9% in 2000-01 to 16.5% in 2019-20 (NHS Digital, 2020). While maternal request and clinical indications often drive the decision for an elective CS, previous obstetric history plays a pivotal role in shaping these choices. As a midwifery student, understanding the interplay between past pregnancy outcomes and current birthing decisions is essential for providing holistic, evidence-based care. This essay explores how previous obstetric history influences the decision to opt for elective CS, focusing on factors such as prior CS, adverse birth outcomes, and psychological impacts. It also considers the broader implications for maternal health and midwifery practice. Through a critical examination of existing literature and official guidelines, this essay aims to highlight the complexities surrounding this topic and the need for individualised care plans.
The Role of Previous Caesarean Sections
One of the most significant factors influencing the decision for an elective CS is a history of prior caesarean delivery. The adage “once a caesarean, always a caesarean” has been largely debunked, yet many women and clinicians remain cautious about vaginal birth after caesarean (VBAC). According to the National Institute for Health and Care Excellence (NICE, 2011), women with a previous CS should be counselled on the risks and benefits of VBAC versus repeat elective CS. However, the risk of uterine rupture during VBAC, though low at approximately 0.5%, often sways decisions towards surgical intervention (RCOG, 2015). Indeed, maternal perception of risk frequently outweighs statistical reassurance, leading to a preference for a planned CS.
Furthermore, a prior CS can influence subsequent pregnancies due to concerns about placental complications, such as placenta praevia or accreta, which are more prevalent in women with uterine scarring (Silver et al., 2006). These potential complications often necessitate an elective CS to mitigate risks to both mother and baby. From a midwifery perspective, it is crucial to provide balanced information, ensuring women understand that while VBAC is a viable option for many, certain obstetric histories may justify a planned surgical approach. This nuanced discussion must be tailored to each woman’s unique circumstances, highlighting the importance of personalised care.
Impact of Adverse Birth Outcomes
Beyond prior CS, other adverse obstetric outcomes, such as stillbirth, neonatal death, or severe maternal morbidity, can also influence the decision for elective CS in subsequent pregnancies. Women who have experienced traumatic birth outcomes often exhibit heightened anxiety about future deliveries, which can drive a preference for surgical intervention as a perceived safer option (Ayers et al., 2016). For instance, a history of shoulder dystocia—a complication where the baby’s shoulders become lodged during vaginal birth—may lead to recommendations for elective CS to avoid recurrence, despite limited evidence guaranteeing better outcomes (RCOG, 2012).
Moreover, the psychological imprint of adverse outcomes cannot be understated. Post-traumatic stress disorder (PTSD) following childbirth, though underdiagnosed, affects approximately 3-6% of women and can significantly shape their future birthing preferences (Ayers et al., 2016). As midwives, it is our responsibility to identify such psychological barriers and collaborate with multidisciplinary teams to offer counselling or interventions that address these fears. While an elective CS may seem like a straightforward solution, it does not always resolve underlying trauma and may even introduce new risks, such as surgical complications or delayed recovery. Therefore, a holistic approach that considers both physical and emotional histories is imperative.
Psychological and Social Dimensions
Previous obstetric history does not operate in isolation; it is often intertwined with psychological and social factors that influence decision-making around elective CS. Women with a history of difficult or traumatic births may experience tokophobia—an intense fear of childbirth—that can manifest as a strong desire for a controlled, surgical delivery (Hofberg and Brockington, 2000). This fear is often compounded by societal narratives that portray vaginal birth as unpredictable or inherently risky, further reinforcing the appeal of elective CS as a means of regaining control.
Additionally, cultural and familial expectations may play a role. For example, in some communities, a previous complicated birth may lead family members to advocate for a CS in subsequent pregnancies, perceiving it as a safer or more modern option (Betran et al., 2016). As midwives, navigating these external pressures requires sensitivity and robust communication skills to ensure that decisions are informed by clinical evidence rather than anecdotal or cultural biases. Critically, while respecting patient autonomy is paramount, it is equally important to challenge misinformation and provide clear, evidence-based guidance.
Clinical Guidelines and Midwifery Practice
Clinical guidelines, such as those from NICE and the Royal College of Obstetricians and Gynaecologists (RCOG), offer frameworks for assessing the suitability of elective CS based on obstetric history. NICE (2011) advises that maternal request for CS should be explored in depth, with an emphasis on understanding underlying reasons, including past experiences. However, these guidelines also highlight the need to balance maternal autonomy with resource constraints and clinical risks, such as increased likelihood of respiratory issues in newborns delivered by elective CS before 39 weeks (NICE, 2011).
From a midwifery standpoint, supporting women with complex obstetric histories involves not only applying these guidelines but also advocating for shared decision-making. This process can be challenging, especially when institutional policies or time constraints limit in-depth discussions. Nevertheless, midwives are uniquely positioned to build trust with women, facilitating conversations that uncover fears or misconceptions tied to previous births. By doing so, we can help ensure that decisions around elective CS are truly informed and reflective of both clinical and personal considerations.
Conclusion
In conclusion, previous obstetric history is a significant determinant in the decision to opt for elective caesarean sections, influenced by factors ranging from prior surgical deliveries to adverse outcomes and psychological impacts. While clinical risks, such as uterine rupture or placental complications, often justify a planned CS, emotional and social dimensions, including birth trauma and cultural expectations, also play a critical role. As this essay has argued, midwives must adopt a holistic approach, integrating clinical guidelines with individualised care to support informed decision-making. The implications for midwifery practice are clear: there is a pressing need for enhanced training in psychological support and communication skills to address the multifaceted influences of obstetric history. Ultimately, by fostering a collaborative, patient-centred environment, midwives can help ensure that choices around elective CS are both safe and empowering, reflecting the unique needs of each woman.
