WASHINGTON, D.C. — In a landmark move to address the escalating crisis of maternal mortality in the United States, the Association of Women’s Health, Obstetric and Neonatal Nurses (AWHONN) has announced the receipt of a $500,000 grant from Merck for Mothers. This significant funding is earmarked for the development and nationwide implementation of the POST-BIRTH Triage Index (PBTI), a pioneering tool designed to standardize how emergency departments (EDs), urgent care centers, and freestanding emergency facilities identify and treat life-threatening postpartum complications.
n
As the United States continues to grapple with the highest maternal mortality rate among developed nations, the PBTI represents a critical evolution in the "fourth trimester" of care. By shifting the focus to non-obstetric clinical settings, where many postpartum patients first seek help for emergencies, AWHONN aims to eliminate the diagnostic delays that too often lead to preventable deaths.

Main Facts: A New Standard for Postpartum Survival
n
The initiative centers on the creation of the first-ever validated, postpartum-specific triage index tailored for clinicians who do not specialize in obstetrics. While labor and delivery units are well-equipped to handle birth-related emergencies, the reality of the American healthcare system is that a woman experiencing a complication three weeks after birth is more likely to visit her local emergency room than her OB-GYN’s office.
n
The PBTI Framework
n
The POST-BIRTH Triage Index (PBTI) is designed to be a clinical decision-support tool. It provides a structured algorithm for triage nurses and emergency physicians to quickly categorize the severity of a postpartum patient’s condition. Unlike general triage tools, the PBTI incorporates specific physiological markers and symptoms unique to the postpartum period—such as late-onset preeclampsia, postpartum cardiomyopathy, and delayed hemorrhage—which can often be masked or misinterpreted as routine exhaustion or minor illness.
n
Targeted Settings
n
The grant specifically targets three high-impact areas:
n
- n
- Hospital Emergency Departments: The primary entry point for acute care.
- Urgent Care Centers: Increasingly used for non-scheduled medical concerns.
- Freestanding Emergency Departments: Facilities that operate independently of a main hospital campus and may lack immediate access to obstetric specialists.

Strategic Partnership
n
The $500,000 grant comes from Merck for Mothers, the global initiative of Merck (known as MSD outside the U.S. and Canada) dedicated to ending maternal mortality. This partnership combines AWHONN’s clinical expertise and nursing network with Merck for Mothers’ global resources and commitment to systemic healthcare improvement.
n
Chronology: From Education to Clinical Intervention
n
The development of the PBTI is not an isolated event but the culmination of over a decade of advocacy and research by AWHONN. To understand the significance of the 2026 rollout, one must look at the evolution of AWHONN’s maternal safety programs.
n
The Foundation: POST-BIRTH Warning Signs (PBWS)
n
In the early 2010s, AWHONN identified that many mothers were being discharged from hospitals without a clear understanding of when a symptom became an emergency. This led to the creation of the POST-BIRTH Warning Signs (PBWS) program. Using the acronym POST-BIRTH (Pain in chest, Obstructed breathing, Seizures, Thoughts of hurting self, Bleeding, Incision that is not healing, Redness or swelling in the leg, Temperature), the program educated patients on when to seek immediate care. Today, this program reaches 1.7 million patients annually.
n
The Research Phase (2023–2025)
n
Prior to the grant announcement, AWHONN conducted extensive research across 23 emergency departments in 17 states. The findings were stark: while patients were increasingly aware of their warning signs (thanks to PBWS), the clinicians they encountered in the ED often lacked the standardized protocols to respond effectively. This "readiness gap" became the catalyst for the PBTI.
n
Implementation Timeline (2026 and Beyond)
n
The grant activates a multi-phase implementation strategy starting in 2026:
n
- n
- Q1-Q2 2026: Establishment of a multidisciplinary expert panel comprising emergency physicians, triage nurses, obstetricians, and patient advocates.
- Q3 2026 – Q2 2027: Execution of three consecutive research studies to validate the PBTI’s efficacy in diverse clinical settings.
- 2027 – 2028: National rollout of the protocol, including the integration of PBTI into Electronic Health Records (EHR) and the expansion of newborn and maternal education resources.

Supporting Data: The High Stakes of the "Fourth Trimester"
n
The necessity of the PBTI is underscored by alarming statistics regarding the postpartum period, often referred to as the "fourth trimester." This period is frequently the most neglected phase of maternal care, yet it is statistically the most dangerous.
The Mortality Window
Data from the Centers for Disease Control and Prevention (CDC) indicates that more than 50% of pregnancy-related deaths occur after the patient has left the hospital. Specifically:
- 1 to 7 Days Postpartum: A high-risk window for immediate complications like hemorrhage and infection.
- 7 to 365 Days Postpartum: The period where the majority of preventable deaths occur, often due to cardiovascular issues, mental health crises, or late-onset preeclampsia.
The "Recognition Gap" in Emergency Medicine
The research conducted across 17 states revealed that in non-obstetric settings:
- History Taking: Clinicians frequently failed to ask female patients of childbearing age if they had recently given birth.
- Vital Sign Interpretation: High blood pressure in a postpartum patient (a sign of eclampsia) was sometimes dismissed as "white coat syndrome" or pain-related stress, rather than an obstetric emergency.
- Standardization: Prior to PBTI, there was no nationally recognized, evidence-based triage tool specifically for postpartum patients in the ED.
Preventability
Perhaps the most compelling data point is that the CDC estimates over 80% of pregnancy-related deaths in the U.S. are preventable. Experts agree that timely recognition and standardized treatment are the two most significant factors in reducing these numbers.
Official Responses: Leadership on the Crisis
The announcement has drawn praise from healthcare leaders who view the grant as a vital investment in the infrastructure of maternal safety.
Jonathan Webb, MBA, MPH, CEO of AWHONN, emphasized the clinical urgency of the project:
"This investment represents a significant step forward in improving maternal safety during one of the most vulnerable periods in a woman’s healthcare journey," Webb stated. "By developing the first validated postpartum-specific triage index for emergency and urgent care settings, we can help clinicians identify life-threatening complications more quickly, improve care coordination and ultimately save lives. We are grateful to Merck for Mothers for partnering with us to advance innovative, evidence-based solutions."
Jacquelyn Caglia, Head of Merck for Mothers, highlighted the importance of health equity and access:
"Merck for Mothers believes that every mother deserves access to high-quality, timely care throughout the postpartum period," said Caglia. "We are honored to support AWHONN’s efforts to expand this important work, building on the success of the Post-Birth Warning Signs program and helping to strengthen systems providing care for families across the United States during this critical time."
Professional nursing organizations have also noted that the PBTI empowers frontline nurses—who are usually the first to see a patient in triage—with the authority and evidence needed to escalate care immediately.
Implications: A Systemic Shift in Maternal Health
The introduction of the POST-BIRTH Triage Index carries profound implications for the future of the American healthcare system, touching on clinical practice, health equity, and policy.
Closing the Communication Loop
One of the primary failures in maternal care is the "siloing" of departments. Obstetricians and emergency physicians often operate in different spheres. The PBTI acts as a bridge, ensuring that the specialized knowledge of AWHONN nurses is translated into a language that emergency department staff can use effectively. This "care coordination" is essential for managing conditions like postpartum cardiomyopathy, which requires specialized cardiology and OB-GYN collaboration.
Advancing Health Equity
Maternal mortality disproportionately affects Black and Indigenous women, who are three to four times more likely to die from pregnancy-related causes than white women. These disparities are often exacerbated by implicit bias in triage settings, where symptoms may be minimized. By introducing a standardized, objective, and evidence-based tool like the PBTI, AWHONN aims to reduce the impact of bias, ensuring that every patient is evaluated against the same rigorous clinical criteria.
Policy and Accreditation
The development of the PBTI may pave the way for new mandates from accrediting bodies like The Joint Commission. If the tool proves successful in reducing mortality during the research phase, it could become a required standard for all emergency departments seeking "Maternal Center of Excellence" designations or similar certifications.
Empowering the "Fourth Trimester"
Ultimately, the PBTI changes the narrative of postpartum care. It reinforces the fact that the year following birth is a critical medical window, not just a social transition. By equipping every emergency room in the country with the tools to handle a postpartum crisis, AWHONN and Merck for Mothers are building a safety net that has been missing for far too long.
As the initiative moves into its implementation phase in 2026, the healthcare community will be watching closely. The success of the PBTI could serve as a global model for how to integrate specialized maternal health protocols into general emergency medicine, potentially saving thousands of lives in the process.
