Weekly measurement
Qualified reach, lift against the national baseline, and reach by state, reported every week.
Patients · DTC panel reach
For HIV, we lead with prescriber targeting. The strictest patient tier did not beat the national baseline in our last test, so we don't make a patient lift claim here.

Common questions
How many prescribers treat HIV?
12,453 active Type 1 NPIs in the treating specialties (infectious disease), 7,849 of them matched to a home address for CTV, streaming and display. Another 705,983 referring prescribers are counted separately. Counts come from the CMS NPPES registry, September 2026.
Why lead with prescriber targeting for HIV?
The strictest patient tier for HIV did not beat the national baseline in the last Audience Quality Test, so Semcasting makes no patient lift claim here. Prescriber targeting by NPI, at home and across devices, is the recommended approach.
Does the HIV audience use diagnosis, claims or prescription data?
No. Patient audiences are built from peer-reviewed, population-level public health reporting and population surveys, scored against Semcasting's national adult file. No diagnosis records, claims, prescriptions or PHI are used, and the score says nothing about any one person's health.

How the audience is built
Patient counts for HIV come from physician-reported registries, diagnostic population surveys, and federal (CDC, CMS, NIH) and disease-association reporting, listed above. Each of 251.7M U.S. adult records is scored 0 to 100 for fit to those published patient profiles by age, gender and income, weighted by geographic prevalence (CDC HIV Surveillance 2024 / World Population Review 2025). Qualified means a score of 58 or higher. High-fit means 69 or higher.
How quality is confirmed
Audience quality has historically been confirmed through holdout sampling: a delivered audience is compared with the full national panel at the same fixed score cutoffs, and the difference is reported as lift. During a campaign, the same comparison runs every week on the households actually reached.
What it is not
Qualified audiences are not built from modeled claims data extrapolated from a few locations. They come from peer-reviewed, population-level public health reporting on patient profiles and population surveys. No diagnosis records, claims, prescriptions or PHI are used, and the score says nothing about any one person's health.
