Infectious Disease AdvisorAI-Based Risk Tool Effectively Identifies Patients at High Risk for HIV, STIs

AI-Enhanced Precision: Transforming Risk Assessment in HIV/STI Healthcare

In a recent study published in Open Forum Infectious Diseases, researchers unveiled MySTIRisk, an AI-based tool adept at identifying patients at heightened risk for HIV and sexually transmitted infections (STIs). This tool’s precision in setting optimal risk thresholds underscores a pivotal shift toward data-driven approaches in sexual health clinics, promising more targeted interventions and resource allocation.

Key Points:

• MySTIRisk, an artificial intelligence-based tool, has been developed to assess the risk of HIV, syphilis, chlamydia, and gonorrhea.
• The study utilized retrospective, cross-sectional data from patients at the Melbourne Sexual Health Center, covering 2008 to 2022, to determine MySTIRisk’s optimal cutoff thresholds.
• The analysis involved large cohorts undergoing consultations for HIV (216,252), syphilis (227,995), gonorrhea (262,599), and chlamydia (320,355).
• Median MySTIRisk scores were 0.32 for HIV, 0.35 for syphilis, 0.37 for gonorrhea, and 0.42 for chlamydia, with higher scores observed in patients who tested positive.
• The optimal cutoff score for high HIV risk was identified as 0.56, with an 86% sensitivity and 65.6% specificity, where 35% of the consulted patients were deemed high-risk.
• For syphilis, gonorrhea, and chlamydia, the optimal cutoff scores were 0.49, 0.52, and 0.47, respectively, with corresponding sensitivities and specificities indicating substantial predictive value.
• Patients classified as high-risk had a significantly elevated likelihood of testing positive across all STIs examined.
• The study’s single-center nature and reliance on self-reported data are noted limitations, emphasizing the need for broader validation.
• The findings advocate for AI’s role in enhancing the precision of risk assessment in sexual health clinics, potentially guiding more effective resource distribution and intervention strategies.

“[T]he findings of this study have important implications for policy and practice in sexual health clinics. The alternative way of defining the high-risk population for risk assessment tools for HIV/STIs can guide resource allocation and intervention strategies.”
