Which approach represents the use of digital tools and technologies to support prevention, screening, and treatment in substance use disorders?

• A. Personalized Medicine With Genetics And Biomarkers
• B. Digital Health Interventions
• C. Expanded Harm-Reduction Approaches
• D. Integrated Care Models

Answer: (B)

Digital health interventions involve using digital tools—apps, online platforms, telehealth, text messaging, and wearable tech—to support prevention, screening, and treatment of substance use disorders. This approach meets people where they are, delivering information and care through devices they use daily, which can boost access, engagement, and timely support.

For prevention, digital tools can provide widespread, scalable education, risk screening, and brief interventions that reach people before or as they begin problematic use. For screening, online or app-based assessments and telehealth evaluations allow quick, confidential identification of risky use or dependence, often facilitating rapid referral to care. For treatment, digital health interventions include internet-delivered therapies (like online cognitive-behavioral programs), mobile apps that help with cravings or adherence, and telemedicine or remote monitoring that connect patients with clinicians without in-person visits. These tools can be personalized, offer real-time feedback, and integrate data to track progress over time.

Context matters: the rise of smartphones, broadband access, and supportive policies has made digital health a practical, scalable option in many settings. However, effectiveness depends on solid evidence, user engagement, and strong privacy protections, and not all populations have equal access to digital resources.

Other approaches emphasize tailoring treatment based on biology, expanding harm-reduction strategies, or coordinating care across settings. While those can include digital elements, the emphasis here is on using digital tools as the means to deliver prevention, screening, and treatment across the continuum.
