Clinical Report: Automated ED Alert System Identifies Undiagnosed HIV
Overview
A nontargeted, opt-out HIV screening program in a Detroit emergency department identified 176 patients with previously undiagnosed HIV from November 2019 through October 2025.
Background
The ongoing HIV epidemic presents significant public health challenges, with millions living undiagnosed. Routine HIV screening, particularly in emergency departments, is crucial for early diagnosis and treatment. This study evaluates an innovative approach to enhance HIV detection and care linkage in a high-volume clinical setting.
Data Highlights
| Metric | Value |
|---|---|
| Patients screened | 75,914 |
| New HIV diagnoses | 176 |
| Test positivity rate | 0.23% |
| Median age of patients | 33 years |
| Linkage to care within 90 days | 59% |
| Median time to ART initiation | 9 days |
Key Findings
- 176 new HIV diagnoses were made during the study period.
- 67% of diagnoses were prompted solely by the automated electronic advisory.
- 59% of patients linked to care within 90 days of diagnosis.
- The median baseline viral load was 95,953 copies/mL.
- 66% of patients achieved viral suppression at 3 months post-diagnosis.
Clinical Implications
Emergency departments can play a role in identifying undiagnosed HIV cases through systematic screening protocols.
Conclusion
The implementation of an automated alert system in emergency departments identified a significant number of undiagnosed HIV cases.
