Veristat, a full-service Contract Research Organization headquartered outside of Boston, Massachusetts, is an industry leader for its top notch services in CDISC Implementation. Veristat became an active member of CDISC in 2007, and earned Registered Solution Provider (RSP) status in 2009. Veristat is one of only 15 companies currently recognized by CDISC as an RSP. In addition Veristat has entered into a partnership with Phase Forward’s Lincoln Safety Group to license the WebSDM tool to assist with validating our SDTM conversions. The WebSDM application was developed under a Cooperative Research and Development Agreement between the FDA and Phase Forward’s Lincoln Safety Group and has been in use at the FDA since 2004.
In regards to CDISC Implementation there are key components that need to be considered to ensure that the resulting data is SDTM compliant. These components include: Gap analysis, Study/Trial Design, Annotated CRF, Data Migration, Define.xml, and Validation. This article will focus on the importance of the first component, Gap analysis.
Gap analysis, as defined by Veristat, is the process of capturing and reviewing key documents and files to support migration efforts. The required documents and files include all versions of the following as available: blank CRFs, SAS datasets, format catalogs, protocols, protocol amendments, statistical analysis plans and clinical study reports. In addition to verifying all appropriate files needed for migration have been received, Veristat cross-checks these documents for their consistency. For example, do the CRFs accurately represent the data collected (or vice-versa) and similarly do the protocol amendments match the CRF versions used? Veristat will track all discrepancies and work with our clients to resolve any identified inconsistencies.
The key advantages to performing a Gap Analysis include being proactive verses reactive, defining the scope of effort and identifying the impact of data collection on migration activities. Being proactive is the key benefit of performing the Gap Analysis early in the process, especially with legacy data migrations where the structure of these files and the availability of the required data are often uncertain. Often, a thorough review of the CRFs and the source data will be a good indication of the effort needed in the migration. For example, in some cases, CRFs may look similar across two studies, but different standards used in the database (because of vendor changes) may make one study much easier to migrate. The basic intent of a Gap Analysis is to identify potential issues early on in the process that will impact migration efforts later.
