ABSTRACT : Data transfer specifications (DTS), drafted by the data management team, carries information on how the non-CRF related raw data should be transferred for integration with clinical study database. The specifications are finalized after due feedback from the biostatistics, vendors, and the programming team. With the advent of decentralized trials and increase in device data, DTS hold a potential to not only define a dataset but also a potential to delay the go live of a clinical trial if the trial transfers are not carefully tested in time. In this paper, we will discuss the general contents of DTS and what aspects of DTS are to be reviewed from programming standpoint with few examples. This paper will also discuss about certain approaches on pre-programming activities to map data not only as per CDISC SDTM standards but also from analysis standpoint to make data mapping easier on receipt of live raw data. INTRODUCTION: Significant amounts of data...
