This database holds the records used in the PhysioNet/CinC Challenge 2012. See the page for more details.

The data used for the 2012 challenge consist of records from 12,000 ICU stays. All patients were adults who were admitted for a wide variety of reasons to cardiac, medical, surgical, and trauma ICUs. ICU stays of less than 48 hours have been excluded. Patients with DNR (do not resuscitate) or CMO (comfort measures only) directives were not excluded.
Four thousand records comprise training set A, and the remaining records form test sets B and C. Outcomes are provided for the training set records, and are withheld for the test set records.
Up to 42 variables were recorded at least once during the first 48 hours after admission to the ICU. Not all variables are available in all cases, however. Six of these variables are general descriptors (collected on admission), and the remainder are time series, for which multiple observations may be available.
Each observation has an associated time-stamp indicating the elapsed time of the observation since ICU admission in each case, in hours and minutes. Thus, for example, a time stamp of 35:19 means that the associated observation was made 35 hours and 19 minutes after the patient was admitted to the ICU.
Each record is stored as a comma-separated value (CSV) text file. To simplify downloading, participants may download a zip file or tarball containing all of training set A or test set B. Test set C was used for validation only and is not available here.
