PurposeThe Japanese Intensive care PAtient Database (JIPAD) was established to construct a high-quality Japanese intensive care unit (ICU) database.Materials And MethodsA data collection structure for consecutive ICU admissions in adults (≥16 years) and children (≤15 years) has been established in Japan since 2014. We herein report a current summary of the data in JIPAD for admissions between April 2015 and March 2017.ResultsThere were 21,617 ICU admissions from 21 ICUs (217 beds) including 8416 (38.9%) for postoperative or procedural monitoring, defined as adult admissions following elective surgery or for procedures and discharged alive within 24 h, 11,755 (54.4%) critically ill adults other than monitoring, and 1446 (6.7%) children. The standardized mortality ratios (SMRs) based on the Acute Physiology and Chronic Health Evaluation (APACHE) III-j, APACHE II, and Simplified Acute Physiology Score II scores in adults ranged from 0.387 to 0.534, whereas the SMR based on the Paediatric Index of Mortality 2 in children was 0.867.ConclusionThe data revealed that the SMRs based on general severity scores in adults were low because of high proportions of elective and monitoring admission. The development of a new mortality prediction model for Japanese ICU patients is needed.Copyright © 2019 Elsevier Inc. All rights reserved.
