The National Transportation Safety Board (NTSB), established in 1967, issues safety recommendations to the organizations best able to take corrective action following the investigation of transportation accidents. Since its founding, the NTSB has issued more than 15,500 safety recommendations, of which 82 percent of closed recommendations have been implemented. This track record is the direct result of three structural features: independence of the investigating body from the regulated industry, specificity of the recommendations including named recipients and measurable outcomes, and systematic tracking of implementation status until each recommendation is formally closed.
The following 24 safety recommendations are issued in the NTSB format and spirit. They address specific safety deficiencies in American obstetric practice identified through analysis of adverse outcome investigation methodology, reporting infrastructure, standard-of-care definition, communication systems, institutional accountability, and clinician support. Each recommendation is addressed to the entity with the authority and responsibility to implement it.
These recommendations do not assign fault. They identify the system changes that the evidence shows are necessary to reduce the rate of preventable obstetric adverse outcomes in the United States.
Response requested: Recipients are requested to respond within 90 days with a description of actions taken or planned to implement each recommendation.
Establish an independent National Obstetric and Birth Safety Investigation (NOBSI) modeled on the NTSB, with authority to investigate every maternal death and every case of birth-related HIE
+
Establish an independent National Obstetric and Birth Safety Investigation (NOBSI), modeled on the National Transportation Safety Board, with the authority and resources to investigate every maternal death and every case of birth-related hypoxic-ischemic encephalopathy occurring in the United States, regardless of the institution's accreditation status or the presence or absence of a pending legal claim.
RATIONALE
The United States has no independent, nationally mandated investigative body for obstetric adverse outcomes. The NTSB has investigated more than 153,000 aviation accidents since 1967 using consistent methodology. An equivalent body does not exist for the approximately 700 maternal deaths and thousands of birth-related brain injuries that occur each year in the United States.
NTSB PARALLEL
The NTSB was created because no independent body existed to investigate aviation accidents without institutional conflict of interest. The same structural gap exists in obstetrics today.

Enact federal litigation protection for investigation findings, modeled on 49 U.S.C. § 1154(b), to encourage complete and honest investigation
+
Enact federal legislation granting findings of the National Obstetric and Birth Safety Investigation (NOBSI) the same protection from admission into evidence in civil litigation that applies to NTSB accident investigation reports under 49 U.S.C. § 1154(b), in order to encourage complete and honest investigation without fear that findings will be weaponized in subsequent legal proceedings.
RATIONALE
The absence of litigation protection is the single most commonly cited reason that institutions resist transparent adverse outcome investigation. Aviation accident investigation findings have been protected from civil discovery since the NTSB's founding, and this protection is credited as a foundational reason why aviation safety investigations are honest. Medicine needs the same protection to achieve the same transparency.
NTSB PARALLEL
Federal statute 49 U.S.C. § 1154(b) bars NTSB accident reports from admission as evidence in civil proceedings. This protection is foundational to honest investigation in aviation.

+
Develop and publish a standardized Obstetric Adverse Outcome Investigation Protocol specifying the required phases of investigation, the minimum documentation standards for each phase, the qualifications of investigators, the required timeline for completion, and the format of the final report — and require adherence to this protocol as a condition of institutional professional organization membership.
RATIONALE
Our professional organizations currently publish no standardized methodology for investigating obstetric adverse outcomes. The Joint Commission framework is generic, applies only to accredited institutions, and has been documented in the peer-reviewed literature as generating "checkbox" compliance rather than genuine learning. A specialty-specific, evidence-based investigation protocol is the minimum institutional standard the field requires.
NTSB PARALLEL
The NTSB publishes detailed investigation manuals for each transport mode. Methodology standardization is the prerequisite for reproducible findings and cross-institutional learning.

Revise Sentinel Event Policy to require explicit standard-of-care, causation, and damage analysis with named responsible parties and measurable outcomes
+
Revise the Sentinel Event Policy to require that root cause analyses of obstetric sentinel events address each of the four legal elements of malpractice — duty, breach of the standard of care, causation, and damage — explicitly and in writing, and to specify that a root cause analysis is incomplete if it does not produce at least one system-level corrective action with a named responsible party, a measurable outcome metric, and a defined completion deadline.
RATIONALE
The current Joint Commission framework does not require explicit analysis of the standard of care, causation, or the relationship between identified deviations and the adverse outcome. Research has documented that traditional root cause analyses in obstetrics use inconsistent language, produce personalized blame rather than system analysis, and achieve only 75 percent inter-rater agreement across reviewers examining the same case.
NTSB PARALLEL
NTSB probable cause findings must identify the act or condition that, if corrected, would have prevented the accident. Vague findings are not accepted as complete investigations.

Establish a mandatory national reporting registry for obstetric adverse outcomes with standardized data fields and annual public reporting
+
Establish a mandatory national reporting registry for obstetric adverse outcomes — including all maternal deaths, all intrapartum fetal deaths, all cases of birth-related hypoxic-ischemic encephalopathy, all cases of uterine rupture, and all cases of severe maternal morbidity as defined by the CDC — with standardized data fields, de-identification requirements, and public reporting of aggregate findings on an annual basis.
RATIONALE
The United States has no mandatory national registry for obstetric adverse outcomes equivalent to the NTSB accident database. The Maternal Mortality Review Committees that exist in most states operate with inconsistent definitions, voluntary participation, and no uniform data standards. The result is that patterns across institutions and regions cannot be identified, and national-level learning from individual cases is impossible.
NTSB PARALLEL
The NTSB accident database enables pattern analysis across all transportation accidents. No obstetric equivalent exists. Pattern recognition requires mandatory, standardized data.

Require reporting of obstetric sentinel events to the national registry within 30 days as a condition of continued federal reimbursement

Require all hospitals that provide obstetric care and receive Medicare or Medicaid reimbursement to report all obstetric sentinel events — including maternal deaths, intrapartum fetal deaths, and cases of birth-related hypoxic-ischemic encephalopathy — to the national registry established under Recommendation OB-SR-05, within 30 days of the event, as a condition of continued participation in federal reimbursement programs.
RATIONALE
CMS already conditions hospital participation on compliance with a wide range of reporting requirements. Extending this condition to obstetric adverse outcome reporting would create the universal reporting infrastructure that voluntary systems have failed to produce. Without mandatory reporting, the national registry will suffer the same selection bias that undermines voluntary adverse event reporting systems in every domain where they have been tried.
NTSB PARALLEL
Aviation accident reporting to the NTSB is federally mandated. Voluntary reporting always produces selection bias — events most likely to reveal systemic failure are least likely to be reported.

Develop a standardized obstetric adverse event classification system analogous to NTSB accident codes to enable aggregate pattern analysis
+
Develop a standardized obstetric adverse event classification system — analogous to the NTSB's accident classification codes — that categorizes each adverse outcome by event type, probable cause category, contributing factor categories, and system-level failure domains, and require that all reported events be classified using this system to enable aggregate pattern analysis across institutions and time.
RATIONALE
Consistent classification is the foundation of aggregate learning. Without standardized categories, a national registry produces a collection of individual narratives rather than actionable intelligence. The NTSB's classification system allows it to identify, for example, that controlled flight into terrain accounts for a specific proportion of fatal accidents — and to track whether that proportion changes as a result of safety interventions. Obstetric medicine has no equivalent capability.
NTSB PARALLEL
Standardized NTSB classification codes enable cross-accident pattern analysis across all modes of transport. Without equivalent coding, obstetric data remain narratives, not intelligence.

Require written determination of the "last safe moment" as a required element of every adverse outcome probable cause analysis
+
Require that every obstetric adverse outcome investigation include a written determination of the "last safe moment" — the specific point in the clinical course at which a different decision would have produced a materially different outcome — as a required element of the probable cause analysis, modeled on the NTSB's practice of identifying the point at which an accident became unrecoverable.
RATIONALE
The "last safe moment" concept forces investigators to anchor their analysis to a specific clinical decision point rather than diffusing responsibility across a general narrative. It is the clinical equivalent of the NTSB's identification of when a crash became unrecoverable. Without this anchor, investigations tend to describe what happened without specifying what, if changed, would have prevented it.
NTSB PARALLEL
NTSB investigations identify when an accident became unrecoverable — the point of no return. This temporal anchor converts narrative into causal analysis.

+
Require that every obstetric adverse outcome investigation include an explicit counterfactual analysis — a written assessment of what the expected outcome would have been had the applicable standard of care been followed at each identified decision point — and that this analysis be completed before any probable cause determination is finalized.
RATIONALE
Counterfactual analysis is the methodological tool that distinguishes causation from correlation in adverse event investigation. The NTSB applies it systematically: not merely "what happened" but "what would have happened differently." Without counterfactual analysis, an investigation can identify a deviation from the standard of care without establishing whether that deviation caused the adverse outcome.
NTSB PARALLEL
NTSB investigations systematically ask: had the crew acted differently, would the accident have been prevented? This counterfactual question is the foundation of causal analysis.

Require a structured hindsight bias assessment before any breach determination is finalized
+
Require that every obstetric adverse outcome investigation include a structured hindsight bias assessment — a documented evaluation of whether each clinical decision under review was consistent with what was knowable at the time the decision was made, rather than with what was known after the outcome occurred — and that this assessment be conducted before any breach determination is finalized.
RATIONALE
Hindsight bias is one of the most reliably documented cognitive errors in adverse event investigation and malpractice analysis. Investigators consistently overestimate the foreseeability of outcomes that have already occurred. The NTSB guards against this by requiring investigators to reconstruct the information available to crew members at each decision point. An equivalent discipline is needed in obstetric investigation if breach determinations are to be epistemically sound.
NTSB PARALLEL
NTSB investigators reconstruct what the crew knew at each decision point — not what investigators know after the fact. This methodological discipline makes findings fair and reproducible.

RATIONALE
The NTSB tracks recommendation implementation and explicitly investigates whether prior unimplemented recommendations contributed to subsequent accidents of the same type. The comparable concept in medicine — that a recurring adverse event following a prior unimplemented recommendation represents institutional failure, not individual error — is rarely articulated and almost never investigated.
NTSB PARALLEL
The NTSB explicitly investigates whether prior unimplemented recommendations contributed to subsequent accidents. Recurring accidents after unimplemented recommendations are institutional failures, not individual ones.

Establish a standing Obstetric Standard of Care Review Panel publishing annually updated, specific clinical reference standards for common adverse outcome scenarios
+
Establish a standing Obstetric Standard of Care Review Panel charged with publishing, updating annually, and publicly releasing a comprehensive statement of the accepted standard of care for each of the clinical scenarios most commonly associated with obstetric adverse outcomes — including electronic fetal monitoring interpretation and response thresholds, decision-to-incision intervals for emergency cesarean delivery, postpartum hemorrhage recognition and treatment thresholds, and preeclampsia management — in language sufficiently specific to serve as an investigation reference standard.
RATIONALE
The "standard of care" in obstetric adverse outcome investigations is routinely contested because no authoritative, specific, publicly available statement of what the standard requires at each clinical decision point exists. Our professional organizations' practice bulletins are deliberately permissive, using language such as "may be considered" and "reasonable to offer" in circumstances where the evidence clearly favors a specific course of action. This vagueness protects members from criticism but makes honest breach analysis impossible.

RATIONALE
The purpose of a protocol in adverse outcome investigation is not to dictate clinical care — it is to create a reference standard against which actual care can be compared. A protocol that says "consider early intervention" cannot be used to assess whether intervention was appropriately timed. Specificity is the prerequisite for accountability.
NTSB PARALLEL
Aviation checklists specify exact actions, sequences, and responsible crew members. "Consider" is not a checklist item. Specificity is what makes protocol adherence assessable.

Require that every labor and delivery unit implement a standardized, structured communication protocol — such as SBAR (Situation, Background, Assessment, Recommendation) or an equivalent validated tool — for all clinical handoffs, all nurse-to-physician escalations, and all emergency team activations, and that adherence to this protocol be assessed as a required element of every obstetric adverse outcome investigation.
RATIONALE
Communication failure is the root cause identified most frequently in obstetric adverse outcome investigations and the proximate cause in the majority of obstetric malpractice claims. The NTSB identified crew resource management failures as a contributing factor in numerous fatal aviation accidents and subsequently tracked the aviation industry's adoption of standardized communication protocols as a safety intervention.

Crew Resource Management (CRM), including standardized communication protocols, was mandated across aviation following NTSB findings that communication failure was a leading cause of fatal accidents.

RATIONALE
Informed consent failure is consistently identified as a contributing factor in obstetric malpractice claims, yet no standardized documentation requirement exists that specifies what an adequate informed consent conversation must contain. A signature on a generic form does not constitute documentation that informed consent occurred. The standard must specify content, not merely process.

Pre-flight briefings in aviation are standardized and documented by content — not merely by occurrence. A signature that a briefing occurred does not document what was communicated.

Require a formal chain-of-command escalation policy specifying steps, timeframes, and documentation when a clinical concern is dismissed by an attending physician

Require that every labor and delivery unit implement a formal chain-of-command escalation policy that specifies the steps a nurse, midwife, or resident must take when a clinical concern is dismissed by an attending physician, the timeframe within which each escalation step must occur, and the documentation required at each step — and that every obstetric adverse outcome investigation include a specific assessment of whether the chain of command was available, known to the team, and used.
RATIONALE
The absence of a usable chain-of-command escalation pathway is a recurring system-level finding in obstetric adverse outcome investigations. When a nurse identifies a Category III EFM tracing and the attending physician does not respond, the clinical decision point is not the nurse's — it is the system's. An investigation that assigns individual responsibility for a chain-of-command failure without examining whether the chain existed and was known to the team is not a system investigation. It is blame.
NTSB PARALLEL
Aviation CRM establishes that any crew member may challenge a captain's decision. The hierarchy is made safely bypassable when safety requires it. Obstetrics requires the same structured escalation pathway.

RATIONALE
Staffing inadequacy is a system-level factor in obstetric adverse outcomes that is consistently identified and consistently unaddressed by individual case investigations because correcting it requires institutional and regulatory action beyond the authority of any clinical department. The NTSB approach assigns recommendations to the entity with the authority to make the required change — not to the individual at the scene of the accident.

RATIONALE
Fatigue is a documented contributor to clinical error and has been the subject of multiple NTSB investigations and recommendations in aviation and other transport modes. The NTSB specifically examines crew rest, duty hours, and cumulative fatigue as potential contributing factors in every investigation involving human performance. Obstetric adverse outcome investigations rarely document the work schedules of the clinicians involved.
NTSB PARALLEL
The NTSB documents crew rest periods and duty hours in every investigation involving human performance. Fatigue is a system failure, not a personal one. Individual breach cannot be assessed without it.

RATIONALE
Alert fatigue — the systematic override of clinically relevant EHR alerts — is an underinvestigated system-level contributor to adverse outcomes. The aviation equivalent is crew failure to respond to ground proximity warnings and traffic collision avoidance advisories, which the NTSB has investigated and addressed through training and system redesign recommendations. In obstetrics, alert override rates are rarely measured.

RATIONALE
The NTSB's Safety Recommendation is its primary product. It is addressed to the entity with the power to act, specifies the required action in unambiguous terms, and is tracked until closed. The obstetric equivalent — a recommendation buried in a peer review document that is protected from disclosure, addressed to no one in particular, and never tracked — produces no accountability and changes nothing. The Safety Recommendation Report format is the mechanism by which investigation findings become institutional change.

RATIONALE
A safety recommendation with no follow-up mechanism is an aspiration, not an accountability tool. The NTSB tracks the implementation status of every recommendation it has ever issued and classifies each as Open-Acceptable, Open-Unacceptable, or Closed. The 82 percent implementation rate it reports is the product of this tracking discipline. Without equivalent follow-up, obstetric safety recommendations will continue to be generated and ignored at the same rate they have been for decades.

RATIONALE
The purpose of investigation is learning, and learning requires dissemination. An investigation whose findings are known only to risk management and hospital administration produces no clinical change. The NTSB makes its accident reports and safety recommendations publicly available specifically because transparency is what converts individual case findings into industry-wide improvement. The clinical team that experienced the adverse event deserves to know what the investigation found and what is being done about it.

All NTSB accident reports and safety recommendations are publicly available. Transparency is not a courtesy — it is the mechanism by which individual case findings become system-wide learning.

RATIONALE
Protocol changes that are announced but not trained produce no change in clinical behavior. The aviation equivalent — the NTSB's longstanding recommendation that cockpit procedure changes be accompanied by simulator training before implementation — is grounded in decades of evidence that cognitive habit change requires practice under realistic conditions, not notification. The same principle applies to obstetric clinical protocols, handoff communication standards, and emergency response sequences.

RATIONALE
The "second victim" phenomenon — the documented psychological harm experienced by clinicians involved in adverse patient outcomes — is a patient safety issue, not merely a clinician welfare issue. Clinicians experiencing untreated psychological distress following adverse events demonstrate measurable increases in subsequent clinical error rates. An investigation process that compounds the distress of involved clinicians without providing support is not only ethically inadequate — it is counterproductive to the safety goals the investigation is intended to serve.
NTSB PARALLEL
Aviation recognizes that crew psychological state following a critical incident affects subsequent performance and safety. Clinician support after adverse events is not a kindness — it is a safety measure that reduces the risk of subsequent error.
