326 Chapter 13 CONCLUSIONS Data extracted from EHRs using text-mining can be used to identify patients eligible for trial participation and for the collection of baseline characteristics. This method might substantially reduce time and costs related to recruitment and data collection in clinical trials. Whether this premise can be realized depends on whether small accuracy losses are deemed acceptable in the context of the trial that is performed. This study focused on patient eligibility screening and participant baseline data collection; future research is needed to assess the quality of outcome detain EHRs. ACKNOWLEDGMENTS The authors would like to show their gratitude to Marjan van Doorn (Meander Medical Center) and Erik Badings (Deventer Hospital) for assisting with the data collection for this study.
