Chlamydia Screening Practices in the Private Sector:
Who, How Much, and Why?
![Page 2: Joanne Armstrong, MD 1,2 Haleh Sangi-Haghpeykar, PhD 1 Alice Shen, MD 1 1. Baylor College of Medicine Houston, Texas 2. Dept Women’s Health, Aetna Chlamydia.](https://reader030.fdocuments.us/reader030/viewer/2022032722/56649ce65503460f949b36c6/html5/thumbnails/2.jpg)

How big is the problem?– 3M infections/year; 80% <25 y/o; 80% asymptomatic
Screening helpful– Decreases prevalence when widely instituted1 – Decreases infection sequelae by 50%2
Limited success in translating screening benefits to women in the private health sector– Most Americans receive STD care private sector from
“private practice” physicians3
– Little data on extent and quality of care in private sector.

– Teens: 5%-10%– Adults: 3%-6%
Self-reported adherence with screening guidelines poor3
– 30% PCPs– 54% ObGyns

ConclusionsPhysicians poorly compliant with screening guidelines
Magnitude of non-compliance even greater than physician self-report, particularly for non-pregnant aged 20-25 years (54% vs 8.5%).
Perception of prevalence is low.
Non-screeners more likely to believe that infection prevalence is too low to warrant routine screening.
Majority have no target prevalence above which screening is indicated. Those who do, have high threshold (10%).
