Accident and Forensic Investigation Services

Rely on our highly-qualified team of expert investigators to determine the cause of healthcare-related incidents, deliver remedies, and provide legal support

Accidents happen. But they need not be repeated. At ECRI, our technical and clinical experts work with you to determine what went wrong and why, so we can help you build strategies, procedures and safeguards aimed at preventing future incidents.

After an accident occurs, staff members’ actions must center around restoring safety and maintaining normal operations, and yet, the important investigation work must be handled promptly, thoroughly, and in best practice, independently.

ECRI’s Accident and Forensic Investigation services team has the knowledge and expertise to conduct an unbiased, scientific investigation to uncover and document facts and set your facility on a successful path forward.


With the trusted ECRI name and more than fifty years of partnering with healthcare facilities to promote safety, ECRI can be counted on to help you determine causes and prevent recurrence. ECRI’s team of experts brings independent judgment in a systems approach that considers technology, users, patients, and the environment. Our specialized services include:

  • Patient incident investigations
  • Sentinel event investigations and analyses
  • Root-cause analyses and risk-reduction strategies
  • Technical consultations, gross and microscopic inspections, and biomedical testing
  • Expert witness consultation and testimony
  • Proactive consultations to prevent known hazards

When to call ECRI

ECRI is adept at handling all aspects of investigations and can assist you when an incident occurs. Our experts can handle clinical interviews and record review, biomedical or biomechanical analyses, determination of device failure mechanisms, and simulation of events. ECRI investigators also prepare facilities for any legal discussions or proceedings; they properly document all steps, maintaining the chain of custody of evidence, avoid inappropriate release or alteration of evidence and are able to remain unbiased. ECRI has investigated thousands of incidents all over the country and internationally—our experience and our integrity is invaluable.
