Processing

Web-based processing of PPE analyses allow states and other customers to determine cross-agency caseload size and overlap without disclosing any person-level information.  This approach begins with local processing of person-level or event-level data using computer programs provided by TBO.  Aggregate (non-person level) data resulting from this local processing is up-loaded to TBO’s on-line PPE processor for determination of caseload size and overlap.  Results of this analysis are returned to the user in a convenient Excel format.  These results will include year-of-birth and gender specific estimates of caseload size and overlap as well as instructions for further analysis of these data at the local level.

Web-based PPE processing substantially reduces the cost of determining caseload overlap and the time between data submission and receipt of results.  Web-based processing also eliminates the need for HIPAA “Data Use Agreements” or “Business Associate Agreements” because no personal information is shared with TBO.

Web-based PPE processing (U.S. Patent # 7,139,675 B2) is currently available for Beta testing on a limited basis. 

Full service PPE analysis and reporting continues to be available from TBO.  These services include expert consultation, research design, data analysis, and report preparation.
