Description:
Objective

Compare syphilis investigation yield among patient groups using number needed to interview.

Goal

To increase investigation efficiency.

Study Design

Retrospective review of North Carolina 2015 syphilis investigations, using the number of cases needed to interview (NNTI) and the number of cases and contacts needed to interview (TNTI) to compare yield of new syphilis and HIV diagnoses between patient groups.

Results

We reviewed 1,646 early syphilis cases and 2,181 contacts; these yielded 241 new syphilis cases (NNTI=6.9; TNTI=16.4) and 38 new HIV cases (NNTI=43). Interviews of women (prevalence difference (PD)=6%, 95% CI 12–16), patients <30 years old (PD=5%, 95% CI 1–8), and patients with titer >1:16 (PD=5%, 95% CI 1–9) yielded more new syphilis cases in our adjusted model; no other patient factors increased investigation yield.

Conclusions

NNTI and TNTI are useful measures of efficiency. Prioritizing early syphilis investigation by gender, RPR titer, and age provides small increases in efficiency; no other factors increased efficiency.
