  1. Utilization of Cross-matching Databases to Obtain Chlamydia Re-screening and Re-infection Rates forFamily Planning/Infertility Prevention Project Clinics: Three Years of Data, Rhode Island, 2004-2006 Michael Gosciminski, MT, MPH Public Health Epidemiologist Rhode Island Department of Health

  2. Background • In Rhode Island, medical record reviews were performed to evaluate chlamydia re-screening timeframes and re-infection rates in Infertility Prevention Project (IPP) sites, but it was a time consuming process and not all of the medical records of females testing positive for chlamydia could be reviewed. • In addition, the Rhode Island IPP database was found to have incomplete re-screening data in the early years of the project.

  3. Step 1 IPP Database A list of all Family Planning clinic females with a positive chlamydia test was generated from the Rhode Island IPP database. This list contained: ♦ Medical Record Number of individual, and ♦ Date of Birth MR # DOB

  4. Step 2 IPP Database This list was cross-matched with CERNER by utilizing the two variables from Step 1. From this cross-match, three variables are collected: ♦ Name of individual ♦ Dates of collection of subsequent chlamydia screening specimens, and ♦ Results of subsequent chlamydia screening specimens MR # DOB Cross match #1 CERNER (LIS) Name Date of subsequent testing Results of subsequent testing

  5. Step 3 IPP Database The name of the individual and date of birth from Step 1 and Step 2 were utilized to cross-match with STD-MIS. From this cross-match, one variable was collected; ♦ Treatment data for chlamydia infections MR # DOB Cross match #1 CERNER (LIS) Name Date of subsequent testing Results of subsequent testing Cross match #2 STD*MIS Treatment data

  6. Step 4 Treatment Date (From STD*MIS) Rescreening Date (From Cerner) Calculate length of time between treatment date and the chlamydia re-screening date and Calculate chlamydia re-screening positivity

  7. Results * 2004 was the last year that medical record reviews were performed for the purpose of evaluating treatment and re-screening within IPP/FP clinics
