Objective To describe national rates of sexually transmitted infection(STI)testing and education overall and among patient subgroups in US outpatient physician offices from 2009 to 2016.Design This was a cross-sectional study of the Centers for Disease Control and Prevention’s National Ambulatory Medical Care Survey from 2009 to 2016.Data weights were applied to extrapolate to national estimates.Setting Data were collected from a systematic random sample of outpatient physician office visits throughout USA.Physician office types include free standing clinics,private or group setting practices,centres offering community and mental health services,family planning clinics and health maintenance organisations/other prepaid clinics.Participants All sampled patient visits were eligible for inclusion and were assessed for the provision of STI prevention education and STI testing for chlamydia,gonorrhoea,hepatitis,human papillomavirus(HPV)and HIV.Results Of 7.6 billion total visits,123 million included an STI test.Hepatitis was the most commonly tested STI(9.12 per 1000),followed by chlamydia(6.67 per 1000),gonorrhoea(6.00 per 1000),HIV(5.40 per 1000)and HPV(5.03 per 1000).Testing rates for the three STIs measured for the entire 8-year period increased over time and peaked in 2015 compared with 2009:chlamydia(R2=0.36),HPV(R2=0.28)and HIV(R2=0.51).Testing was highest among women(21.93 per 1000),15-24-year olds(46.04 per 1000),non-Hispanic blacks(37.33 per 1000)and those seen by obstetrics/gynaecology specialists(103.75 per 1000).STI prevention education was provided to 4.89 per 1000 patients and remained relatively unchanged from 2013 to 2016.Conclusion STI testing in outpatient physician offices increased over the study period but varied by patient characteristics and site of care.Few patients received STI prevention education,highlighting a potential gap in resource utilisation in these settings.
