Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 14 years and older
  • Women only
  • Healthy volunteers accepted
  • Child, Adult, Older adult

Study population: The Queens Options Center serves as a referral center for family planning services for patients throughout the state. From prior literature, the patients most impacted by persistent or continued syphilis infections are those who are structurally vulnerable, including those who are under- or uninsured, experiencing poverty, unhoused, or actively using substances. By screening universally, we may decrease the stigmatization associated with individual behavior-based screening. We acknowledge that there is a risk of increased false positives by screening universally . To mitigate this, we recommend that a participant with a positive rapid test also obtain serological testing with RPR, which is already required for treatment monitoring. As stated above, prior studies have established that the sensitivity and specificity of the SHC are greater than 95%.

Who may be able to join

  • 14 years or older
  • Seeking contraception or abortion services
  • Sexually active (engages in any form of sexual activity with another person)
  • Denies history of syphilis infection
  • Can speak and read English
  • Displays capacity for informed consent

Who cannot join

  • Confirmed history (by patient report or medical records) of syphilis
  • Home address outside Hawai'i
  • Currently incarcerated
  • Number of Subjects:
  • Recommendations for sample size in pilot studies range from 70 to 100 patients.28 Given this is a nonrandomized feasibility study with no comparator (i.e., to a control or to serological testing), we aim to enroll 50 to 75 participants to support analysis for correlation between variables while being able to achieve relatively small confidence intervals. This number takes into account the practical considerations of study personnel resources and in-person patient volume in our clinic. All patients eligible for the rapid syphilis testing will be approached for study participation.

Potential Benefits

  • Participants can find out whether they are syphilis positive or negative within the visit, as soon as 10-15 minutes of the finger stick. Typically, syphilis testing results take several days.
  • If positive, there is the option of starting treatment within the same day.

Potential Risks

  • The study team will do everything possible to protect participants' privacy, including removing names and other identifiable information from study materials, however this is still a small chance there may be a breach of privacy during the study.
  • Physical risks of fingerstick are exceptionally rare when sterile technique is used. The study team will be using all best practices to reduce risk of infection or injury.
  • There is a risk of discomfort or pain with fingerstick collection. The risk of scarring is usually only associated with repeat draws, for example in patients with diabetes who have to do fingerstick draws multiple times per day.
  • There is a very small chance that the positive result is incorrect (also known as a "false positive"), meaning the participant does not actually have syphilis. To confirm the result, the investigators recommend that any positive rapid syphilis result be followed up with a blood test at the lab.

Cost for Participation

  • There is no direct cost to participate in this study. After consent is signed, the participant received renumeration of $50 in form of gift card. If the participant tests positive for a syphilis infection, the participant or their health insurance will be responsible cover the costs of this medical treatment. If they do not have access to health insurance, the study team will connect the participant with agencies that have assisted patients with treatment at a reduced cost or free of cost.
Read the detailed description

This is a nonrandomized feasibility study of a clinician-administered point of care rapid syphilis test. The study will take place within the Queen's Medical Center Options Clinic, where the University of Hawai'i Complex Family Planning program is based. The Options Center is a primary referral site for abortion throughout Hawai'i. This study aims to evaluate whether the Syphilis Health Check (SHC), an FDA-approved rapid, point-of-care syphilis test, is feasible and acceptable to patients and providers at a university-associated family planning clinic in Hawai'i. Rapid syphilis testing will be offered to sexually active adults seeking abortion or contraception services. Positive results will be followed by laboratory-based syphilis testing. The investigators hypothesize that rapid syphilis testing at the family planning clinic will be feasible and acceptable to both patients and staff.

If the patient expresses interest in syphilis testing, a research associate will describe the study in further detail and obtain informed consent via a paper-based informed consent document.

All study personnel will undergo the SHC training, which includes an online module and quiz available on the SHC website. Study personnel who are certified to collect the SHC will collect the specimen via fingerstick using a sterile lancet. They will collect the blood using the pipette provided in each kit, then add the blood to the sample well of the SHC cassette. They will then add four drops of diluent to the sample well. The study personnel can read the result at the 10-minute mark, and no later than 15 minutes. Any line in the 'T' zone, even if faint, accompanied by a line in the 'C' zone, will be interpreted as a positive result. The study personnel, if not a family planning provider, will inform the physician of all test results. All participants with a positive SHC test will be recommended to get confirmatory serological testing. All participants will receive their results before the end of their family planning visit.

Traditional serological testing requires external laboratory equipment and facilities. The SHC is read in the clinic without additional equipment or laboratory technicians, thus expediting time from specimen collection to diagnosis. Participants with positive SHC results will require more thorough evaluation to stage and determine appropriate treatment. The physician will conduct a detailed health history and physical exam. The SHC is a qualitative treponemal test; therefore, after their counseling and discussion with the physician, the participant will be asked to go to the laboratory to draw blood for an RPR, for which there is no rapid test. The RPR acts as a confirmatory test while also providing quantitative information to monitor treatment effectiveness.

If the participant is pregnant and desires to continue with pregnancy, then the patient will be referred to a pharmacy or clinic that can administer Bicillin. These may include Queen's pharmacy, other pharmacy, Healthy Mothers Healthy Babies, PATH Clinic, Diamond Head STI Clinic. Additional appointments as needed will be made to complete the treatment (up to 3 total doses of Bicillin). If there is still an ongoing shortage and/or recall of Bicillin at the time of study initiation, the physician will call 808-833-9281 to request an appointment with the Hawai'i Department of Public Health STI/HIV Clinic for assistance with where to refer the patient for Bicillin treatment options. At the time of writing, Bicillin is prioritized for pregnant individuals only. For participants with positive SHC who are terminating pregnancy or who are not pregnant, the alternative treatment is doxycycline per CDC guidelines. The physician will prescribe 2 to 4 weeks of doxycycline 100mg BID based on the staging of infection in accordance with CDC guidelines. Patients will be counseled on increased sun sensitivity with longer durations of doxycycline use, and recommend sun protection.

Positive SHC results that have been confirmed with positive serum RPR will be reported to the State of Hawai'i Department of Health using the Sexually Transmitted Infection Confidential Case Report within three business days per state guidelines, either through mail, fax, or phone .

For partner notification, the study physician will provide resources for patients to share with their partner(s) for testing options. Options will include: 1) the patient informs their sexual partner(s) directly or anonymously through a text-based service; 2) the physician informs their sexual partner(s) via a text-based service; 3) deferring to the public health department to inform their sexual partner(s) through their intervention specialist team.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Rapid Syphilis TestDiagnostic test

    This study aims to evaluate whether the Syphilis Health Check (SHC), an FDA-approved rapid, point-of-care syphilis test, is feasible and acceptable to patients and providers at a university-associated family planning clinic in Hawai'i.

    SHC is specific for detecting Treponema pallidum antibodies in serum, plasma, or whole blood via a rapid immunochromatographic test. It has a sensitivity of 95-99% and a specificity of 94-97%, and has been studied in pregnant patients. The test costs approximately $10, takes 10-15 minutes to yield results, has a shelf life of 30 months, and remains stable at room temperature. The assay can be used as an initial screening test or in conjunction with a non-treponemal laboratory test. Treatment with antibiotics can be started immediately with a positive SHC test.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Acceptability and Feasibility of Rapid Syphilis Testing

    We will assess feasibility with a combination of quantitative and qualitative methods, in accordance with guidelines put forth by Teresi et al for feasibility pilot studies.

    Outcomes:

    • Number of eligible participants
    • Number of participants who completed SHC testing
    • Number of participants who agreed to SHC testing
