Trends in Sexually Transmitted Infections in United States Ambulatory Care Clinics from 2005-2016.

ABSTRACT: We examined the prevalence trends of non-human immunodeficiency virus (HIV) sexually transmitted infections (STI) and associated patient characteristics in U.S. ambulatory-care settings from 2005-2016. We conducted a retrospective repeated cross-sectional analysis using data from the National Ambulatory Medical Care Survey (NAMCS) for individuals aged 15-64 with a non-HIV STI-related visit. Data were combined into three periods (2005-2008, 2009-2012, and 2013-2016) to obtain reliable estimates. Logistic regression was used for analysis. A total of 19.5 million weighted, non-HIV STI-related ambulatory visits from 2005-2016 were identified. STI-related visits per 100,000 ambulatory care visits increased significantly over the study period: 206 (95% CI = 153-259), 343 (95% CI = 279-407), and 361 (95% CI = 277-446) in 2005-2008, 2009-2012, and 2013-2016, respectively (P_trend = 0.003). These increases were mainly driven by increases in HPV-related visits (56 to 163 per 100,000 visits) from 2005-2008 to 2009-2012, followed by syphilis- or gonorrhea-related visits (30 to 67 per 100,000 visits) from 2009-2012 to 2013-2016. Higher odds of having STI-related visit were associated with younger age (aged 15-24: aOR = 4.45; 95% CI = 3.19-6.20 and aged 25-44: aOR = 3.59; 95% CI = 2.71-4.77) vs. 45-64-year-olds, Black race (aOR = 2.41; 95% CI = 1.78-3.25) vs. White, and HIV diagnosis (aOR = 10.60; 95% CI = 5.50-20.27) vs. no HIV diagnosis. STI-related office visits increased by over 75% from 2005-2016, and were largely driven by HPV-related STIs and syphilis- or gonorrhea-related STIs.

Project description:Background & aimsPatients with inflammatory bowel diseases (IBDs) require repeated health care encounters, although the focus of care differs when patients are seen in ambulatory, emergency department (ED), or inpatient settings. We examined contemporary trends and disparities in IBD-related health care visits.MethodsWe used data from the National Ambulatory Medical Care Survey, the Nationwide Emergency Department Sample, and the National Inpatient Sample to estimate the total number of annual IBD-related visits from 2005 through 2016. We performed logistic regression analyses to test temporal linear trends. Slope and differences in distributions of patient demographics were compared across time and treatment settings.ResultsFrom 2005 through 2016, approximately 2.2 million IBD-related ambulatory visits (95 CI, 1.9-2.5) occurred annually on average, increasing by 70.3% from the time period of 2005 to 2007 through the time period of 2008 to 2010, and decreasing by 19.8% from the time period of 2011 to 2013 through the time period of 2014 to 2016. An average of 115,934 IBD-related ED visits (95% CI, 113,758-118,111) and 89,111 IBD-related hospital discharges (95% CI, 87,416-90,807) occurred annually. Significant increases in the rate of IBD-related ED visits (3.2 visits/10,000 encounters; P < .0001) and hospital discharges (6.0 discharges/10,000 encounters; P < .0001) were observed from 2005 through 2016. The proportion of patients paying with private insurance decreased from 2005 through 2016, among all care settings. A greater proportion of young patients, patients with Crohn's disease, non-white patients, and patients with Medicare or Medicaid used hospital-based vs ambulatory services.ConclusionsIn an analysis of data from 3 large databases, we found that although IBD-related ambulatory visits stabilized to decreased from 2005 through 2016, rates of ED use and admission to the hospital have continued to increase with changes in patient demographics, over time and among care settings.

Project description:ImportanceMaternal infection has been implicated in the pathogenesis of preterm birth through intrauterine inflammatory response. Chlamydia, gonorrhea, and syphilis are among the most common sexually transmitted infections worldwide, but studies on their association with preterm birth are sparse.ObjectiveTo examine the association between maternal chlamydia, gonorrhea, and syphilis infections in pregnancy and the risk of preterm birth in a large population-based study in the US.Design, setting, and participantsThis population-based retrospective cohort study examined nationwide birth certificate data from the US National Vital Statistics System between 2016 and 2019. All mothers who had a singleton live birth and available data on chlamydia, gonorrhea, or syphilis infection before or during pregnancy and gestational age at birth were included in analysis.ExposuresSexually transmitted infection (chlamydia, gonorrhea, or syphilis) occurring before or during pregnancy.Main outcomes and measuresPreterm birth, defined as gestational age less than 37 weeks.ResultsThis study included 14 373 023 mothers (mean [SD] age 29 [5.8] years; Hispanic, 3 435 333 [23.9%]; non-Hispanic Asian, 912 425 [6.3%]; non-Hispanic Black, 2 058 006 [14.3%]; and non-Hispanic White, 7 386 568 [51.4%]). Among the mothers, 267 260 (1.9%) had chlamydia, 43 147 (0.3%) had gonorrhea, and 16 321 (0.1%) had syphilis. Among the newborns, 1 146 800 (8.0%) were preterm births. The rate of preterm birth was 9.9%, 12.2%, and 13.3% among women with chlamydia, gonorrhea, and syphilis infection, respectively. After adjustment for sociodemographic and medical and/or health factors, the adjusted odds ratio of preterm birth was 1.03 (95% CI, 1.02-1.04) for chlamydia, 1.11 (95% CI, 1.08-1.15) for gonorrhea, 1.17 (95% CI, 1.11-1.22) for syphilis, and 1.06 (95% CI, 1.05-1.07) for any of these sexually transmitted infections comparing mothers with these conditions and those without.Conclusions and relevanceMaternal sexually transmitted infections (gonorrhea, syphilis, or chlamydia) were associated with an increased risk of preterm birth. Pregnant women with sexually transmitted infections before or during pregnancy might benefit from targeted prevention for preterm birth.

Project description:BACKGROUND:Bacterial sexually transmitted infections may facilitate HIV transmission. Bacterial sexually transmitted infection testing is recommended for sexually active HIV-infected patients annually and more frequently for those at elevated sexual risk. We estimated percentages of HIV-infected patients in the United States receiving at least one syphilis, gonorrhea, or chlamydia test, and repeat (?2 tests, ?3 months apart) tests for any of these sexually transmitted infections from mid-2008 through mid-2010. DESIGN:The Medical Monitoring Project collects behavioral and clinical characteristics of HIV-infected adults receiving medical care in the United States using nationally representative sampling. METHODS:Sexual activity included self-reported oral, vaginal, or anal sex in the past 12 months. Participants reporting more than 1 sexual partner or illicit drug use before/during sex in the past year were classified as having elevated sexual risk. Among participants with only 1 sex partner and no drug use before/during sex, those reporting consistent condom use were classified as low risk; those reporting sex without a condom (or for whom this was unknown) were classified as at elevated sexual risk only if they considered their sex partner to be a casual partner, or if their partner was HIV-negative or partner HIV status was unknown. Bacterial sexually transmitted infection testing was ascertained through medical record abstraction. RESULTS:Among sexually active patients, 55% were tested at least once in 12 months for syphilis, whereas 23% and 24% received at least one gonorrhea and chlamydia test, respectively. Syphilis testing did not vary by sex/sexual orientation. Receipt of at least 3 CD4+ T-lymphocyte cell counts and/or HIV viral load tests in 12 months was associated with syphilis testing in men who have sex with men (MSM), men who have sex with women only, and women. Chlamydia testing was significantly higher in sexually active women (30%) compared with men who have sex with women only (19%), but not compared with MSM (22%). Forty-six percent of MSM were at elevated sexual risk; 26% of these MSM received repeat syphilis testing, whereas repeat testing for gonorrhea and chlamydia was only 7% for each infection. CONCLUSIONS:Bacterial sexually transmitted infection testing among sexually active HIV-infected patients was low, particularly for those at elevated sexual risk. Patient encounters in which CD4+ T-lymphocyte cell counts and/or HIV viral load testing occurs present opportunities for increased bacterial sexually transmitted infection testing.
