MIMIC-III, A FREELY ACCESSIBLE CRITICAL CARE DATABASE MIMIC-III is freely accessible critical care database of patient who stayed in critical care units of the Beth Israel Deaconess Medical Center between 2001 and 2012. It has health related data of over forty thousand people and over fifty thousand hospital admission. In this database data includes fluid balance, drug code, procedure codes, diagnostic codes, imaging reports, laboratory measurements, hospital length of stay, survival data, vital signs, medications, billing, observations and notes charted by care providers at time of ICU stay. In this database the median age of adult patients is 65.8 years, 55.9% patients are male and 44.1% are female, and in-hospital mortality is 11.5%. The median length of an ICU stay is 2.1 days and the median length of a hospital stay is 6.9. A mean of 4579 charted observations (’chartevents’) and 380 laboratory measurements (’labevents’) are available for each hospital admission. This database includes total 26 tables which contains 9 classes of data. Database shows that more than 35% patents were admitted to medical intensive care unit and most of the patient suffered from ischemic heart diseases, diseases of pulmonary circulation, dysrhythmias, heart failure, cerebrovascular diseases, etc. For collecting clinical information like arterial blood pressure, progress notes, respiratory rate, hourly documentation of heart rate, continuous intravenous drip medications and fluid balances – they’ve used two different system which is Philips CareVue Clinical Information System iMDsoft MetaVision ICU. Additional information was collected from hospital and laboratory health record systems, including: ● patient demographics and in-hospital mortality. ● laboratory test results (example, hematology, chemistry, and microbiology results). ● discharge summaries and reports of electrocardiogram and imaging studies. ● billing-related information such as (ICD-9) codes, (DRG) codes, and (CPT) codes. They’ve deidentified all the data before including in MIMIC-III following Health Insurance Portability and Accountability Act (HIPAA) standards. This relational database has total 26 table which is linked to each with identifier provided as comma separated value (CSV). To get the access, researched must complete a recognized course in protecting human research participants and the researcher must sign a data use agreement. MIMIC-III has also uploaded the codes to visualize the information on its GitHub repository.
