1544. Sexually Transmitted Infection Laboratory Testing and Education Trends Among Physician Office Visits in the United States, 2009-2016

BACKGROUND: Rates of sexually transmitted infections (STIs) have been rising in the United States (US). Physician offices play an important role in providing both STI prevention and education, as well as STI laboratory testing options for patients who present at risk. However, few studies have documented the extent to which physician’s offices have contributed to prevention and testing efforts. We address this gap by evaluating STI testing and education provided in US physician offices from 2009 to 2016. METHODS: This was a cross-sectional study of the Centers for Disease Control and Prevention’s National Ambulatory Medical Care Survey (NAMCS) from 2009 to 2016. Data weights were applied to extrapolate sample data to national estimates. Testing for HIV, HPV, Chlamydia (2009 – 2016) and Hepatitis and Gonorrhea (2014 – 2016) were presented as testing visits per 1,000 total visits. Subgroup analyses were performed for age group, sex, and geographical region by individual STI test and receipt of STI prevention education. RESULTS: A total of 7.6 billion visits were included for analysis, of which 0.6% included an STI test. Testing rates increased over the study period for Chlamydia (R(2)=0.27), HPV (R(2)=0.28), and HIV (R(2)=0.51). Peak testing occurred in 2015 for all tests. STI prevention education was provided to 0.5% of patients. Females were tested at a higher rate for all STIs (4.2%) compared to males (0.4%). Females also received more STI prevention education overall (0.6% versus 0.4%, respectively). While the age group 25 – 24 accounted for highest Hepatitis (15.9%) and HPV (11.3%) testing rates, the 15 – 24 age group had the highest overall testing rate (9.4%). STI testing was highest in the South region (Figure 1). [Image: see text] CONCLUSION: STI testing in US physician offices increased in recent years. Females accounted for the majority of STI testing and STI prevention education. Testing was more frequent among patients 15 – 24 years old and those seen in the South region. Further research should be conducted to determine reasons for differences in testing and education amongst sex, age group, and geographic region. DISCLOSURES: All Authors: No reported disclosures
