Lessons Learned in Data Migration at Memorial Hermann

Alan Weiss, MD, Director of Medical Informatics, Memorial Hermann.  Memorial Hermann recently converted their medical group to Cerner ambulatory and migrated the data themselves from the legacy EHR.  While this aspect of the project was key to implementation, it was challenging, time consuming, error prone and revealed significant quality issues within the data.  Sharing the lessons learned should assist other institutions going through any EHR vendor conversions.  Moreover, some of the novel approaches and analyses performed may give insight into better EHR design and use.
