Reporting of laboratory-confirmed chlamydial infection and gonorrhea by providers affiliated with three large managed care organizations--United States, 1995-1 999.

Surveillance for sexually transmitted diseases (STDs) depends on health departments receiving reports of positive STD test results from laboratories or of STD cases by clinicians. The completeness and timeliness of reporting can affect prompt sex partner notification and outbreak detection. In 1998, approximately 70% of chlamydia cases and 55% of gonorrhea cases were reported by private clinicians, including many affiliated with managed care organizations (MCOs). However, little is known about the completeness and timeliness of MCOs' STD case reporting practices. Three MCOs, three state health departments, and CDC evaluated reporting practices for chlamydial infection and gonorrhea by three large staff or group model MCOs that used different reporting procedures. The findings indicate that state health departments were notified of 78%-98% of chlamydia cases and of 64%-80% of gonorrhea cases identified in these MCOs; the median interval between specimen collection and state health department receipt of a case report was < or = 19 days. To improve surveillance quality, other MCOs, including network model MCOs, which provide most STD care in the United States, should evaluate surveillance quality and identify interventions for improvement.
