Improving Maternal and Child Health Through Point-of-care STI Testing

Summary

The goal of this clinical trial is to learn if point-of-care tests (POCTs) for sexually transmitted infections (STIs) improve the timely treatment of syphilis, chlamydia, gonorrhea, and trichomonas in pregnant women. It will also learn about the feasibility, acceptability, and cost-effectiveness of implementing POCTs in a large safety-net hospital setting. The main questions it aims to answer are: * Do POCTs reduce delays in STI treatment compared with standard laboratory-based testing? * What barriers, facilitators, and processes affect POCT implementation in prenatal and obstetric care? * What are the costs and cost-effectiveness of POCTs compared with standard testing? Participants will: * Complete a baseline survey and receive either POCTs (fingerstick blood draw or vaginal swab) or standard laboratory STI testing. * If diagnosed with an STI, complete a follow-up survey approximately one month later. * Stakeholders (providers, hospital leadership, and public health officials) will complete interviews to inform implementation strategies.

Detailed Description

Sexually transmitted infections (STIs) represent a growing public health crisis in the United States, with disproportionate impact among Black women and women residing in the Southeastern region. National surveillance data demonstrate alarming increases in syphilis, with reported cases rising by 937% and congenital syphilis cases increasing by 755% over the past decade. In pregnant women, untreated or delayed treatment of STIs is associated with severe adverse reproductive outcomes, including stillbirth, preterm birth, and vertical transmission to the infant. At Grady Memorial Hospital (GMH), a large safety-net hospital in Atlanta, Georgia, the current standard of care for syphilis diagnosis relies on rapid plasma reagin (RPR) screening, confirmatory treponemal testing, and patient history. This process requires patient recontact for counseling, treatment initiation, and partner notification. Similarly, testing for chlamydia (CT), gonorrhea (NG), and trichomonas (TV) is performed using laboratory-based nucleic acid amplification tests (NAATs), which typically require 1-3 days for results. The absence of same-day diagnostic results creates significant barriers to timely treatment, as recontacting patients is often challenging, and transportation or socioeconomic constraints may limit access to care. STI counseling and treatment at GMH are provided by the clinical team in accordance with the Centers for Disease Control and Prevention (CDC) STI Treatment Guidelines. Recommended regimens include intramuscular benzathine penicillin G (single dose for early syphilis; three weekly doses for latent or unknown duration syphilis), oral azithromycin for chlamydia in pregnancy, intramuscular ceftriaxone for gonorrhea, and a one-week course of oral metronidazole for trichomonas. Patients with positive results are retested per GMH standard of care, consistent with CDC recommendations. Despite adherence to national guidelines, treatment delays remain common among pregnant women presenting to GMH's outpatient prenatal care (PNC) clinic and Labor \& Delivery (L\&D) triage. These delays increase risk of onward transmission, including mother-to-child transmission, and contribute to adverse reproductive outcomes. To address these challenges, multidisciplinary experts in obstetrics, infectious diseases, clinical trials, and implementation science at Emory University have developed the \*\*MATCH-POINT study\*\*. This study will evaluate the effectiveness and scalability of point-of-care tests (POCTs) for syphilis, chlamydia, gonorrhea, and trichomonas in pregnant women receiving care at GMH. GMH serves a predominantly under-resourced patient population with high STI prevalence and elevated maternal and child morbidity and mortality. Findings from MATCH-POINT will inform strategies for integrating POCTs into routine prenatal and obstetric care, with the goal of reducing treatment delays, improving maternal and infant outcomes, and preventing onward transmission. Results will be shared with key stakeholders, including the Georgia Department of Public Health, to guide recommendations for broader implementation and scalability of POCTs across safety-net hospitals and clinics serving under-resourced pregnant women throughout the Southeastern United States.
