Patients' experiences with diagnostic mistakes and delays in outpatient care
Patient-Reported Diagnostic Safety Events in Ambulatory Care Settings: A National Survey of Systemic Influences, Disparities and Persisting Consequences
This project will ask people who had diagnostic problems in outpatient care about what happened, who was affected, and how it affected their lives.

What this research studies
You would be invited to complete a detailed survey about any diagnostic problems you or a family member experienced in outpatient settings between 2020 and 2025. The project will collect both structured answers and open-ended stories so patients can describe what happened and the lasting consequences. Researchers will sample about 3,300 U.S. households to allow comparisons across places like primary care, urgent care, and specialty clinics and among different patient groups. The survey uses new methods to better capture patient-reported safety events and the system-level factors behind them.
Who could benefit from this research
Good fit: Ideal participants are people or family members in the United States who experienced a diagnostic problem, delay, or related harm in an outpatient setting between 2020 and 2025.
Not a fit: People who never experienced an outpatient diagnostic problem or whose issues were only during inpatient hospital stays are unlikely to be eligible or directly helped by this project.
Why it matters
Potential benefit: If successful, the findings could help reduce outpatient diagnostic mistakes and delays by showing where problems happen and who is most affected.
How similar studies have performed: Previous research has relied on smaller or inpatient-focused samples, so this nationally representative, patient-reported approach is relatively new though built on earlier patient-report work.
