^aBased on operating hours of the STD Clinic (Wednesday, Thursday, Friday from 12:30PM-3:30PM), holidays excluded, plus an additional hour for administrative tasks.

^bFor the purposes of this analysis, it was assumed all people with a positive syphilis test were treated with one intramuscular penicillin G benzathine (Bicillin L-A®) injection, individuals with a positive chlamydia test were treated with azithromycin 1 gram orally once, and individuals with a positive gonorrhea test were treated with ceftriaxone 250mg intramuscularly once and azithromycin 1 gram orally once.

^cBased on visits where insurance was used to bill (Appendix Table 2 provides Medicaid income estimates). Actual clinic only billed for laboratory testing but not for treatment and provider time. Reimbursement rates were based on the Medicaid fee schedule, a low estimate.
