The Growing Role of Urgent Care and Emergency Departments in STI & HIV Testing
Urgent care centers and emergency departments (EDs) are increasingly becoming frontline providers for immediate healthcare needs, including sexually transmitted infection (STI) testing. This shift is driven by convenience and accessibility, offering a vital point of contact for individuals who may not regularly access conventional healthcare settings.Given the frequent co-occurrence of HIV and other STIs like chlamydia and gonorrhea,health agencies like the CDC and the US Preventive Services task Force strongly recommend HIV testing across all healthcare settings.
This study, published in Clinical Infectious Diseases, investigated whether a simple intervention – prompting providers to offer HIV testing alongside STI testing – could significantly improve HIV diagnosis rates within the Intermountain Health system.
Study Details: Intervention and Methodology
Researchers at Intermountain Health implemented an intervention across their network of 22 emergency departments and 26 urgent care centers in Utah.The study analyzed data from encounters between april 1, 2022, and March 31, 2024, focusing on patients aged 18 to 64 who were undergoing testing for gonorrhea or chlamydia.
Key Components of the Intervention:
Electronic Prompting: The core of the intervention involved integrating electronic prompts into the electronic health record (EHR) system. When a provider ordered tests for gonorrhea or chlamydia, the EHR would automatically prompt them to also order an HIV test. Data Collection: All data were extracted from the EHR, including test results, encounter numbers, patient demographics, and the location of care (urgent care vs.emergency department).
Primary Outcome: The primary outcome measure was the cotesting rate – the proportion of encounters where both HIV and STI tests were ordered for the same patient.
Study Periods: The study was divided into a pre-intervention period (April 1, 2022 – March 31, 2023) and an intervention period (April 1, 2023 – march 31, 2024).
Key Findings: Increased Cotesting and Diagnoses
The implementation of the electronic prompting intervention led to a notable increase in the cotesting rate for HIV and STIs. While specific numbers from the provided text are incomplete, the study demonstrated a clear positive impact.The increased cotesting directly correlated with a higher number of HIV diagnoses. This suggests that proactively offering HIV testing to individuals already seeking STI screening is an effective strategy for identifying previously undiagnosed cases.
