摘要:Chlamydia, a sexually transmitted infection, is the most commonly reported nationally notifable disease in the United States We assessed the completeness of key variables included in chlamydia case report data submitted to the Centers for Disease Control and Prevention (CDC) during 2012. Most of the reviewed demographic and geographic variables provided to CDC on 2012 chlamydia case reports had complete values. Diagnosis-related variables provided on case reports were less complete, in particular anatomic specimen site. Further investigation is needed to identify barriers to submitting complete data. Additional evaluation of validity (e.g., accuracy) of data provided is needed to fully evaluate chlamydia case report data.
