The Joint Commission (TJC) is aligning its Sentinel Event (SE) List with the National Quality Forum’s (NQF) updated Serious Reportable Events (SRE) List, with the transition taking effect no later than January 1, 2027. The change is intended to reduce reporting burden, eliminate duplicative classification systems, and establish greater consistency in how serious patient safety events are defined and addressed.
The Joint Commission continues to expect accredited organizations to identify sentinel events, analyze root causes and contributing factors, and implement improvements to reduce the risk of recurrence. Alignment with the NQF framework is particularly significant for organizations operating in states with mandatory SRE reporting, where differences between state and TJC definitions have created additional reporting and classification requirements.
The updated TJC Sentinel Event List will adopt 28 NQF Serious Reportable Events, along with the NQF inclusion criteria and clinical application guidance. The revised list will be organized into four patient-focused categories:
• Procedural Events
• Product/Device Events
• Patient Protection Events
• Care Provision Events
Of the 28 SREs, 13 correspond to events already recognized by The Joint Commission, while 15 will be added as individual events. The revised list will also retain three legacy workforce safety events involving the homicide, sexual abuse or assault, and physical assault of staff members.
The updated framework expands attention to several areas that may require organizations to reassess their event identification and reporting processes. Examples include MRI-related injuries and safety events, radiotherapy errors, contaminated drugs or devices, medical-device misuse or malfunction, medical-gas events, equipment-related fires, restraint or seclusion-related harm, medication errors, unintended burns, and serious pressure injuries.
The transition does not change the voluntary nature of reporting events directly to The Joint Commission. However, organizations must continue to evaluate state-specific laws and regulations, which may establish mandatory SRE reporting requirements independent of TJC reporting.
Healthcare organizations should use the transition as an opportunity to review their event-reporting policies, definitions, escalation processes, patient safety surveillance, and regulatory reporting requirements. Organizations should also evaluate the TJC/NQF crosswalk to identify changes between the current Sentinel Event List and the updated SRE framework.
Early review will help organizations determine whether existing policies, event-reporting systems, staff education, and leadership oversight adequately address the revised definitions before the January 2027 implementation date.
The alignment represents an important step toward a more standardized taxonomy for serious patient safety events, while preserving state-specific reporting obligations where applicable.
