Not much is known about the fitness of use of electronic health record data for secondary use at larger integrated health systems. We used the data completeness dimensions defined by Weiskopf et al. to assess the fitness of EHR data for secondary uses at Ochsner health system. This work provides valuable insights into the degree of data completeness over time and has the potential to inform future efforts to develop data completeness guidelines for secondary use cases. This work highlights the extent of data completeness at an integrated health system over a period of 8 years. Increased adoption of EHRs in the last twelve years has increased the documentation and breadth of data in the EHR. However, data density, after temporal and linear adjustments as described by Sperrin et al., has not changed very much over the years and may be the limiting factor when determining the amount of “usable” data for secondary use.
