SRGE Dataset* Template

Variable Required or Optional Description Example Values Comments/Other Requirements
Case Status Required Binary identifier of early syphilis cases
  • 1 = Presence of Disposition Code for Primary, Secondary or Early Syphilis (710, 720, 730)
  • 0 = Otherwise
 Case status must be a binary variable
Case definition may be modified based on health department needs and/or priorities
Age Group Required Categorical variable indicating age
  • 11-19
  • 20-24
  • 25-29
  • 30-34
  • 35-39
  • 40-44
  • 45-49
  • 50-54
  • 60-64
  • 65-69
  • 70+
 Cut-points and age range are flexible and can be defined based on age distribution of population of interest
Titer Value Required Categorical variable indicating titer result from RPR or VDRL test
  • Non-R
  • 1:1
  • 1:2
  • 1:4
  • 1:8
  • 1:16
  • 1:32+
 Qualitative titer values can be included or excluded from reactor grid. SRGE does not provide support for cleaning or grouping qualitative results
Gender Optional Categorical variable indicating gender
  • Male
  • Female
 If data is available on lab report, gender can be used to reflect sexual preference or non-binary gender
Test Type Optional Categorical variable indicating type of non-treponemal test performed
  • RPR
  • VDRL
 All lab reports should correspond to non-treponemal tests only.
Blood false positives (i.e., negative treponemal test, but reactive non-treponemal test) should be accounted prior to importing data into SRGE
Previous Result Optional Categorical variable indicating change in titer from previous result 1 = Less than 2 titer increase
0 = New positive or 2+ titer increase		 Comparison to previous result must be performed prior to importing data into SRGE.
Example SAS code for comparing results is available here: Sample SAS Code for Comparing Current and Previous Result

*Data set requirements: Data set should be in a .txt or .csv format and include all lab reports for non-treponemal tests (RPR and/or VDRL labs) from the specified time period. Blood false positives (i.e., reactive non-treponemal tests with a negative treponemal test) should be excluded prior to importing data into SRGE.
