Background CDC began development of Performance Measures in 1999 and 58 Project Areas have continuously reported on the measures twice yearly since 2005. Two Performance Measures from Juvenile Detention Centers (screening in 2004 and positivity in 2009) were developed to capture the burden of chlamydia infection in this underserved population of adolescent females.
Objectives To assess changes in performance of screening of females in juvenile detention centers (JDC's) from the US as reported through Performance Measures and to obtain a measure of the positivity detected.
Methods 50 US States, six US cities, Washington, DC and Puerto Rico are asked to report the percentage of females screened for chlamydia twice yearly from all juvenile detention centers that admit 500 or more adolescent females annually. Project Areas with no facilities that admit 500 or more are to report on one or more facilities of their choice. A chlamydia positivity measure was added in 2009. We collapsed the 2 half-yearly reports for each Project Area into yearly summaries from 2005 to 2009.
Results The percentage of Project Areas that were able to report any chlamydia screening from their JDC's increased from 60% in 2005 to 84% in 2009. The mean percentage of Project Areas reporting any screening over the 5 years was 80%. Many Project Areas reported from multiple JDC's during 2005–2009 with California reporting from 12 facilities and Ohio reporting from 11 facilities. The reported percentage of juvenile females screened by year were 54, 63, 59, 60 and 51% from 2005 to 2009. The percentage screened ranged from 3% to 100%. The mean percentage of females screened over the 5 years was 57%. In 2009, the mean chlamydia positivity for all Project Areas was 13.8%. For facilities (n=69) that screened at least 100 females in 2009, the mean chlamydia positivity detected was 13.7%, with a median of 12.6% and positivity ranging from 6 to 31%. Almost half (48%) of the Project Areas reported from 49 facilities for all 10 reporting periods across the 5-year period. The percentage screened in these 49 facilities increased 59, 64, 66, 69 and 69% from 2005 to 2009. The mean per cent positivity for these facilities in 2009 was 12.5%.
Conclusions Juvenile Detention Centers are excellent venues from which to detect chlamydia infections in adolescent females. Additional efforts are needed to increase the number of facilities that routinely offer screening and increase the proportion screened.
