12.2 Incident Reporting, Root Cause Analysis & Learning from Reviews (MNSI, MBRRACE)

Incident Reporting, Root Cause Analysis & Learning from Reviews (MNSI, MBRRACE)

Providing safe, high-quality maternity care requires relentless vigilance, transparent incident reporting, and continuous organizational learning. Healthcare systems that punish individuals for honest human errors inadvertently create cultures of concealment, denial, and recurring harm. Following landmark national inquiries into catastrophic NHS maternity failures, UK maternity care has fundamentally transformed its approach to clinical governance, safety investigations, and multidisciplinary accountability.

Midwives must master the principles of clinical governance, incident reporting via the Learn from Patient Safety Events (LFPSE) service, system-based accident investigations, and the findings of national confidential enquiries such as MBRRACE-UK and MNSI.

Clinical Governance & Risk Management in Maternity Services

Clinical governance was defined by Scally and Donaldson (1998) as: "A framework through which NHS organisations are accountable for continuously improving the quality of their services and safeguarding high standards of care by creating an environment in which excellence in clinical care will flourish."

In maternity care, clinical governance is structured around seven mutually reinforcing pillars:

1. Risk Management: Identifying, assessing, mitigating, and monitoring clinical risks through robust reporting systems, proactive risk registers, and incident investigations.
2. Clinical Audit: Systematically measuring local practice against national evidence-based criteria (e.g., NICE, RCOG) and implementing corrective actions to close quality gaps.
3. Clinical Effectiveness & Research: Ensuring clinical care reflects up-to-date, peer-reviewed evidence and national clinical guidelines, rejecting outdated dogma.
4. Education and Training: Mandatory, regular interprofessional simulation training (such as PROMPT — PRactical Obstetric Multi-Professional Training) where midwives, obstetricians, and anaesthetists train together in real-world environments.
5. Patient and Public Involvement (PPI): Engaging women, families, and Maternity and Neonatal Voices Partnerships (MNVPs) to co-design services and evaluate care quality.
6. Staffing and Staff Management: Maintaining safe staffing ratios (such as Birthrate Plus recommendations for 1-to-1 care in labour), fair recruitment, and restorative clinical supervision for registered midwives (for example, through the A-EQUIP model and Professional Midwifery Advocates).
7. Information and Digital Systems: Accurate, real-time documentation, data collection, and integration of electronic maternity records (e.g., BadgerNet).

Incident Reporting Systems & The "Just Culture"

Incident reporting is the cornerstone of risk management. In England, the Learn from Patient Safety Events (LFPSE) service has replaced the National Reporting and Learning System (NRLS) and StEIS. Midwives usually report through their trust's local risk management system (such as Datix or Ulysses), which sends the data to LFPSE.

What Must Be Reported?

Midwives are required to submit an electronic incident report for any unexpected adverse event, safety incident, or near miss, including:

• Maternal complications: severe postpartum haemorrhage (>1,500 mL), unheralded uterine rupture, eclamptic seizure, accidental dural puncture during epidural siting, 3rd or 4th-degree perineal tears.
• Fetal/neonatal complications: unexpected term admission to the Neonatal Intensive Care Unit (NICU), cord prolapse, severe shoulder dystocia, Apgar score <7 at 5 minutes, fetal trauma.
• Medication errors: ten-fold drug dosing errors, wrong-route administrations (e.g., IV epidural infusion), missed prophylactic antibiotics in Group B Streptococcus, omitted anti-D immunoglobulin.
• Environmental and operational risks: severe midwifery understaffing breaching safe staffing guidelines, lack of available birthing beds, failure of telemetry/monitoring equipment, delayed ambulance transfers.

The "Just Culture" Paradigm

Historically, healthcare operated within a toxic blame culture, where incident reports were weaponized to scapegoat frontline clinicians. This drove errors underground.

The modern NHS operates under a Just Culture framework (supported by the NHS England Just Culture Guide). A Just Culture does not mean an absence of accountability; rather, it distinguishes between three distinct categories of human conduct:

Root Cause Analysis & James Reason's Swiss Cheese Model

When a severe clinical incident occurs, healthcare systems historically used Root Cause Analysis (RCA) under the Serious Incident Framework. In England, this has been replaced by the Patient Safety Incident Response Framework (PSIRF), which all NHS trusts had adopted by autumn 2023. These methodologies shift focus away from individual finger-pointing toward understanding the complex, interconnected systems within which clinicians operate.

The theoretical bedrock of modern accident investigation is James Reason's Swiss Cheese Model of System Accidents:

                       THE SWISS CHEESE MODEL (James Reason)

└────────┬─────────┘
         │
         ▼
  HARM / ADVERSE OUTCOME (e.g., Intrapartum Asphyxia / Severe HIE)

In Reason's model, a system consists of multiple defensive barriers designed to prevent hazards from reaching the patient (e.g., clinical guidelines, double-checking, continuous fetal monitoring, MEOWS escalation algorithms, senior consultant presence). However, each defensive layer has weaknesses and vulnerabilities—represented by the holes in slices of Swiss cheese.

• Latent Conditions: Weaknesses embedded deep within organizational systems, policies, and management structures long before an incident occurs. Examples include chronic staff shortages, cost-cutting measures, fatigue-inducing shift rosters, lack of simulation facilities, poor IT infrastructure, and an unsupportive management culture.
• Active Failures: Unsafe acts, omissions, errors, or slips committed by frontline clinicians directly interacting with the patient. Examples include miscalculating a drug dose, misinterpreting a CTG baseline, or failing to activate the emergency buzzer.
• The Trajectory of Accident Causation: Under normal circumstances, holes in individual defensive slices do not align; a latent weakness is intercepted by another defensive layer (e.g., an incorrect drug dose drawn up by one midwife is detected and stopped by the independent second checker). However, when multiple latent conditions and active failures align simultaneously, a trajectory of accident opportunity opens straight through all defensive barriers, leading to catastrophic patient harm.

Investigations under PSIRF aim to identify and patch the latent organizational holes rather than merely punishing the frontline clinician who happened to be holding the final slice of cheese.

Maternity and Newborn Safety Investigations (MNSI)

In 2018, the Healthcare Safety Investigation Branch (HSIB) began a maternity investigation programme in England. Since October 2023 it has operated as the Maternity and Newborn Safety Investigations (MNSI) programme, hosted by the Care Quality Commission (CQC).

MNSI conducts independent, high-level, standardized investigations into severe intrapartum maternity incidents across England. Crucially, MNSI is independent of individual NHS Trusts, does not attribute individual blame, does not determine civil negligence, and engages the affected family at every stage of the inquiry.

MNSI Referral Criteria

NHS trusts in England are expected to refer cases that meet the MNSI criteria. For babies, these apply to term births (37 completed weeks or more) following labour, including the latent phase and induction of labour:

1. Intrapartum Stillbirth: The baby was thought to be alive at the start of labour but was born with no signs of life.
2. Early Neonatal Death: Death of a baby from any cause within the first 7 days of life (days 0 to 6).
3. Potential Severe Brain Injury: Diagnosed in the first 7 days of life, for example a baby who receives therapeutic hypothermia (cooling) or has moderate to severe encephalopathy. Babies with genetic or congenital conditions are excluded, and cooled babies without evidence of ongoing brain injury are no longer routinely investigated (they are still referred).
4. Maternal Deaths: Direct or indirect maternal deaths while pregnant or within 42 days of the end of pregnancy, excluding suicide.

MNSI safety investigators deploy to the hospital, interview clinical staff and family members, review medical records and electronic telemetry, analyze the human factors environment, and publish public safety reports with national learning recommendations.

MBRRACE-UK: Surveillance & Confidential Enquiries

MBRRACE-UK (Mothers and Babies: Reducing Risk through Audits and Confidential Enquiries across the UK) is the national collaboration responsible for the Maternal, Newborn and Infant Clinical Outcome Review Programme. It provides the most comprehensive epidemiological surveillance of maternal and perinatal mortality in the UK.

Key Epidemiological Classifications

MBRRACE-UK categorizes maternal deaths into three vital legal and clinical definitions:

• Direct Maternal Death: Death resulting from obstetric complications of the pregnant state (pregnancy, labour, and puerperium), from interventions, omissions, or incorrect treatment (e.g., amniotic fluid embolism, massive obstetric haemorrhage, pre-eclampsia, genital tract sepsis).
• Indirect Maternal Death: Death resulting from previously existing disease, or disease that developed during pregnancy and was not due to direct obstetric causes, but which was aggravated by the physiological effects of pregnancy (e.g., cardiac disease, psychiatric disorders, epilepsy, influenza).
• Late Maternal Death: Death occurring between 42 days and one year after the end of pregnancy from either direct or indirect causes.

Major Findings from MBRRACE-UK Enquiries

Stark Health Inequalities & Ethnic Disparities

One of MBRRACE-UK's most alarming and persistent findings is the profound health inequality in maternal mortality:

• In the 2026 report (2022–24), Black women were nearly three times as likely to die as White women (RR 2.72), down from almost four times in earlier reports.
• Asian women had a slightly higher rate than White women (RR 1.27), which was not statistically significant in this period.
• Women living in the most deprived 20% of areas had about twice the maternal mortality rate of those in the least deprived 20% (RR 1.94).

These disparities are driven by systemic structural inequities, unconscious racial bias, language barriers, social deprivation, and failure of healthcare professionals to listen to and believe Black and Asian women when they report pain or deteriorating symptoms. The NMC Code mandates anti-discriminatory practice; midwives must actively advocate for racially marginalized women, dismantle diagnostic overshadowing, and ensure equitable access to specialist multidisciplinary care.

Landmark National Maternity Inquiries: Lessons for Midwifery

Contemporary UK maternity policy and regulation have been shaped profoundly by three landmark independent inquiries into systemic failures:

1. The Morecambe Bay Investigation (Dr Bill Kirkup, 2015)

• Context: Investigated the catastrophic deaths of 11 babies and 1 mother at Furness General Hospital between 2004 and 2013.
• Key Findings: Identified a lethal, pervasive culture of dysfunctional team dynamics between midwives and obstetricians, characterized by tribalism, hostility, and suspicion. A small, insular group of midwives—calling themselves "the musketeers"—pursued "normal birth at all costs", actively refusing to escalate high-risk complications or involve obstetricians. Midwives operated outside clinical guidelines, clinical records were withheld or destroyed, and Trust management repeatedly covered up failures.
• Systemic Changes: Led to the abolition of statutory supervision of midwives in its historic regulatory form, establishment of the A-EQUIP model (Advocating and Educating for QUality ImProvement) and Professional Midwifery Advocates (PMAs), and the national mandate for joint multidisciplinary emergency training.

2. The Ockenden Independent Review of Maternity Services (Donna Ockenden, 2020 & 2022)

• Context: Investigated Shrewsbury and Telford Hospital NHS Trust (SaTH), examining 1,592 clinical incidents involving 1,486 families (mostly between 2000 and 2019), including stillbirths, neonatal deaths, maternal deaths and babies left with brain injury.
• Key Findings: Exposed catastrophic, systematic failures: a culture of denial where grieving parents were ignored, blamed, or treated with callous indifference; clinical incidents were never investigated or learned from; institutional targets were set to artificially depress caesarean section rates (leading to traumatic, delayed births and brain damage); failure to recognize fetal heart rate abnormalities; and severe lack of board-level oversight.
• Systemic Changes: The Ockenden Reports established mandatory Immediate and Essential Actions (IEAs) across all English NHS maternity services, including ring-fenced funding for multidisciplinary training, mandatory 1-to-1 care in labour, enhanced maternal fetal medicine oversight, and the appointment of Board-level Safety Champions.

3. Reading the Signals: Maternity & Neonatal Services in East Kent (Dr Bill Kirkup, 2022)

• Context: Investigated safety failures across East Kent Hospitals University NHS Foundation Trust, reviewing 202 cases. The panel found that the outcome could have been different in 97 cases (48%), including 45 of the 65 baby deaths (69%).
• Key Findings: Revealed a recurring pattern of "sub-optimal clinical judgment", grotesque institutional arrogance, bullying, and tribal warfare between day and night staff and between professions. When tragedies occurred, management's default response was "the management of reputational risk" rather than compassionate engagement with families.
• Systemic Changes: Demanded radical cultural change, unified professional standards across midwifery and obstetrics, national teamworking programs, and mechanisms to ensure the voices of women and families are heard and acted upon immediately.
