Patient-Reported Experiences Filling Expedited Partner Therapy Prescriptions for Chlamydia, Including Recommendations for Mitigating Encountered Obstacles, New York City, 2019 to 2020.

BACKGROUND: Expedited partner therapy (EPT) is commonly provided by prescription. Multiple barriers to prescription-EPT have been described, although information on patient experiences with this practice is limited. METHODS: We conducted telephone interviews from July 2019 to January 2020, with women aged 15 to 24 years who were reported to the New York City Department of Health with chlamydia and for whom a health care provider report indicated provision of prescription-EPT (patients). A standard questionnaire was used to explore patients' experiences with filling an EPT prescription for their most recent sex partner and included questions about factors that would make it easier to obtain EPT medication. RESULTS: A total of 425 young women were reported with chlamydia and indicated to have received prescription-EPT. We completed interviews with 245 of these patients (57.6%), of whom 204 affirmed receiving prescription-EPT (83.3%). Nearly all patients (193 of 204 [94.6%]) took actions to fill the EPT prescription (visited the pharmacy themselves (139 of 193 [72.0%]) or directed their partner to fill the prescription (54 of 193 [28.0%]). Among these patients, most reported obtaining medication (173 of 193 [89.6%]). A small number of patients reported ways to enhance EPT practices, including 22, 19, and 12 who reported factors related to payment, health care providers, and the pharmacy, respectively, that would make it easier to obtain medication. Patients highlighted the importance of reducing cost and increasing convenience. CONCLUSIONS: Most interviewed patients successfully filled EPT prescriptions. However, some patients encountered barriers during the process. Approaches to streamline EPT practices, such as provision of medication-EPT at the point of care, are critical.

Effectiveness of Syphilis Partner Notification After Adjusting for Treatment Dates, 7 Jurisdictions.

BACKGROUND: Disease intervention specialists (DIS) prevent syphilis by ensuring treatment for patients' sex partners through partner notification (PN). Different interpretations of how to measure partners treated due to DIS efforts complicates PN evaluation. We measured PN impact by counting partners treated for syphilis after DIS interviewed the patient. METHODS: We reviewed data from early syphilis cases reported during the 2015-2017 period in 7 jurisdictions. We compared infected partners brought to treatment using the following: (1) DIS-assigned disposition codes or (2) all infected partners treated 0 to 90 days after the patient's interview (adjusted treatment estimate). Stratified analyses assessed patient characteristics associated with the adjusted treatment estimate. RESULTS: Disease intervention specialists interviewed 23,613 patients who reported 20,890 partners with locating information. Many of the 3569 (17.1%) partners classified by DIS as brought to treatment were treated before the patient was interviewed. There were 2359 (11.3%) partners treated 0 to 90 days after the patient's interview. Treatment estimates were more consistent between programs when measured using our adjusted estimates (range, 6.1%-14.8% per patient interviewed) compared with DIS-assigned disposition (range, 6.1%-28.3%). Treatment for ≥1 partner occurred after 9.0% of interviews and was more likely if the patient was a woman (17.9%), younger than 25 years (12.6%), interviewed ≤7 days from diagnosis (13.9%), HIV negative (12.6%), or had no reported history of syphilis (9.8%). CONCLUSIONS: Counting infected partners treated 0 to 90 days after interview reduced variability in reporting and facilitates quality assurance. Identifying programs and DIS who are particularly good at finding and treating partners could improve program impact.

Unnamed Partners From Syphilis Partner Services Interviews, 7 Jurisdictions.

BACKGROUND: Reducing transmission depends on the percentage of infected partners treated; if many are missed, impact on transmission will be low. Traditional partner services metrics evaluate the number of partners found and treated. We estimated the proportion of partners of syphilis patients not locatable for intervention. METHODS: We reviewed records of early syphilis cases (primary, secondary, early latent) reported in 2015 to 2017 in 7 jurisdictions (Florida, Louisiana, Michigan, North Carolina, Virginia, New York City, and San Francisco). Among interviewed syphilis patients, we determined the proportion who reported named partners (with locating information), reported unnamed partners (no locating information), and did not report partners. For patients with no reported partners, we estimated their range of unreported partners to be between one and the average number of partners for patients who reported partners. RESULTS: Among 29,719 syphilis patients, 23,613 (80%) were interviewed and 18,581 (63%) reported 84,224 sex partners (average, 4.5; 20,853 [25%] named and 63,371 [75%] unnamed). An estimated 11,138 to 54,521 partners were unreported. Thus, 74,509 to 117,892 (of 95,362-138,745) partners were not reached by partner services (78%-85%). Among interviewed patients, 71% reported ≥1 unnamed partner or reported no partners; this proportion was higher for men who reported sex with men (75%) compared with men who reported sex with women only (65%) and women (44%). CONCLUSIONS: Approximately 80% of sex partners were either unnamed or unreported. Partner services may be less successful at interrupting transmission in networks for men who reported sex with men where a higher proportion of partners are unnamed or unreported.

Frequency and Characteristics of Biological False-Positive Test Results for Syphilis Reported in Florida and New York City, USA, 2013 to 2017.

Discordant syphilis test results, with a reactive nontreponemal test and nonreactive treponemal test are usually considered biological false-positive test results (BFPs), which can be attributed to other conditions. Syphilis surveillance laws mandate laboratory reporting of reactive syphilis tests, which include many BFPs. We describe the frequency of BFPs, titer distributions, and titer increases from reported test results in Florida and New York City (NYC). Reactive nontreponemal tests for individuals with at least one nonreactive treponemal test and no reactive treponemal test were extracted from sexually transmitted disease (STD) surveillance systems in Florida and NYC from 2013 to 2017. Characteristics of individuals with BFPs were analyzed after selecting the observation with the highest titer from each individual. We next considered all results from individuals to characterize persons who had a 4-fold titer increase between successive nontreponemal tests. Among 526,540 reactive nontreponemal tests, there were 57,580 BFPs (11%) from 39,920 individuals. Over 90% (n = 52,330) of BFPs were low titer (≤1:4), but 654 (1%) were high-titer BFPs (≥1:32). Very high-titer (≥1:128) BFPs were more common among individuals over 60 years of age (odds ratio [OR], 2.68; 95% confidence interval [CI], 1.22 to 5.91). A 4-fold increase in titer was observed among 1,863 (14%) individuals with more than one reported BFP. Most BFPs detected by surveillance were low titer, but some were high titer and some had a 4-fold increase in titer. Review of patient histories might identify underlying conditions contributing to these high and rising titers.

The Epidemiology of Syphilis in New York City: Historic Trends and the Current Outbreak Among Men Who Have Sex With Men, 2016.

BACKGROUND: Male primary and secondary (P&S) and early latent syphilis cases have increased markedly in New York City (NYC) after a historic nadir in 1998. The majority of cases are among men who have sex with men (MSM). We describe the epidemiology of syphilis among NYC males to provide a model of how 1 jurisdiction collects, analyzes, interprets, uses, and disseminates local data to guide programmatic activities directed at syphilis control. METHODS: We analyzed trends in reported infectious syphilis cases using routinely collected surveillance and case investigation data. Human immunodeficiency virus (HIV) coinfection status was ascertained by routine deterministic match between sexually transmitted infection and HIV surveillance registries, and self-report. We mapped diagnosing facilities to display the relative contribution of different public/private facilities. Characteristics of male syphilis cases diagnosed in public sexual health (SH) clinics were compared to those diagnosed elsewhere. RESULTS: During 2012 to 2016, male P&S syphilis case rates increased 81%, from 24.8 to 44.8/100,000 (1832 cases in 2016); the highest rates were among black non-Hispanic men. Overall, 87.6% (902/1030) of interviewed men in 2016 disclosed 1 or more male partner. The HIV coinfection rates are high among MSM with P&S syphilis (43.4%; 394/907 in 2016), but appear to be decreasing (from 54.1% in 2012). Maps highlight SH clinics' contribution to diagnosing P&S syphilis cases among men of color. HIV coinfection rates were lower among men with P&S syphilis diagnosed in SH clinics than among those diagnosed elsewhere (34%, SH clinics vs 49%; other settings, P < 0.0001). CONCLUSIONS: Syphilis infections continue to increase among MSM in NYC. Novel interventions responsive to the drivers of the current outbreak are needed.

Sexually transmitted infection clinics as safety net providers: exploring the role of categorical sexually transmitted infection clinics in an era of health care reform.

BACKGROUND: For many individuals, the implementation of the US Affordable Care Act will involve a transition from public to private health care venues for sexually transmitted infection (STI) care and prevention. To anticipate challenges primary care providers may face and to inform the future role of publicly funded STI clinics, it is useful to consider their current functions. METHODS: Data collected by 40 STI clinics that are a part of the Sexually Transmitted Disease Surveillance Network were used to describe patient demographic and behavioral characteristics, STI diagnoses, and laboratory testing data in 2010 and 2011. RESULTS: A total of 608,536 clinic visits were made by 363,607 unique patients. Most patients (61.9%) were male; 21.9% of men reported sex with men (MSM). Roughly half of patients were 20 to 29 years old (47.1%) and non-Hispanic black (56.2%). There were 212,765 STI diagnoses (mostly nonreportable) that required clinical examinations. A high volume of chlamydia, gonorrhea, and HIV testing was performed (>350,000 tests); the prevalence was 11.5% for chlamydia, 5.8% for gonorrhea, 0.9% for HIV, and varied greatly by sex and MSM status. Among MSM with chlamydia or gonorrhea, 40.1% (1811/4448) of chlamydial and 46.2% (3370/7300) of gonococcal infections were detected at extragenital sites. CONCLUSIONS: Sexually Transmitted Disease Surveillance Network clinics served populations with high STI rates. Given experience with diagnoses of both nonreportable and reportable STIs and extragenital chlamydia and gonorrhea testing, STI clinics comprise a critical specialty network in STI diagnosis, treatment, and prevention.

Population-based surveillance for neonatal herpes in New York City, April 2006-September 2010.

BACKGROUND: Population-based data for neonatal herpes simplex virus (HSV) infection are needed to describe disease burden and to develop and evaluate prevention strategies. METHODS: From April 2006 to September 2010, routine population-based surveillance was conducted using mandated provider and laboratory reports of neonatal HSV diagnoses and test results for New York City resident infants aged ≤60 days. Case investigations, including provider interviews and review of infant and maternal medical charts and vital records, were performed. Hospital discharge data were analyzed and compared with surveillance data findings. RESULTS: Between April 2006 and September 2010, New York City neonatal HSV surveillance detected 76 cases, for an average incidence of 13.3/100,000 (1/7519) live births. Median annual incidence of neonatal HSV estimated from administrative data for 1997 to 2008 was 11.8/100,000. Among surveillance cases, 90.8% (69/76) were laboratory confirmed. Among these, 40.6% (28/69) were HSV-1; 39.1% (27/69) were HSV-2; and 20.3% (14/69) were untyped. The overall case-fatality rate was 17.1% (13/76). Five cases were detected among infants aged >42 days. In all, 80% (20/25) of the case-infants delivered by cesarean section were known to have obstetric interventions that could have increased risk of neonatal HSV transmission to the infant before delivery. Over half (68%, or 52/76) of all cases lacked timely or ideal diagnostics or treatment. CONCLUSIONS: Administrative data may be an adequate and relatively inexpensive source for assessing neonatal HSV burden, although they lack the detail and timeliness of surveillance. Prevention strategies should address HSV-1. Incubation periods might be longer than expected for neonatal HSV. Cesarean delivery might not be protective if preceded by invasive procedures. Provider education is needed to raise awareness of neonatal HSV and to assure appropriate testing and treatment.

The elephant never forgets; piloting a chlamydia and gonorrhea retesting reminder postcard in an STD clinic setting.

We examined the number and proportion of persons retesting and reinfected with Chlamydia and/or gonorrhea 3 to 4 months after initial infection in one New York City sexually transmitted disease clinic using a reminder postcard compared to clinics not using this reminder. Retesting increased; however, the proportion reinfected was lower during the intervention.
