MIMIC II Waveform and Clinical Databases Updated

Version 3 of the MIMIC II Waveform Database has been publicly released. Version 3 contains 21,422 patient records and is more than 4 times the size of version 2. Using enhanced data recovery techniques, the original raw data dumps have been reprocessed to extract many records that were previously unreadable, and additional raw data dumps collected since the previous release were also processed to obtain many more records. Also available to qualified investigators via PhysioNetWorks is version 2.6 of the companion MIMIC II Clinical Database, containing data for 32,536 subjects (5880 new since version 2.5) and additional data types (including demographics, procedure (CPT) codes, diagnosis-related groups (DRG codes), Elixhauser comorbidity scores, microbiology test results, and LOINC coding for lab tests).
