Background: The use of continuous renal replacement therapy (CRRT) in critically ill children is rapidly increasing, but the standard of care has not yet been established and prognosis remains poor. To develop optimal CRRT strategies, we launched a research project generating the Japanese Pediatric CRRT registry, a multicenter registry of CRRT in Japanese pediatric intensive care units (PICUs), to investigate the actual status of CRRT in recent years in PICUs, where data are lacking.
Methods: This manuscript presents a protocol for planning a multicenter prospective registry. As of April 2023, 15 Japanese PICUs are voluntarily participating. Patients enrolled are those <16 years of age who enter the PICUs of the collaborating institutions, require CRRT, and have the guardians' consent. CRRT is defined as anticipated to be required for >24 hours, and CRRT connected to extracorporeal membrane oxygenation is also included. The registry is an online registry system managed by the University Hospital Medical Information Network. The primary outcomes are Pediatric Cerebral Performance Category Scale at PICU discharge and 6 months post-discharge (deaths included), persistent need for dialysis, and PICU readmission within 6 months. The secondary outcomes are adverse events during and immediately after CRRT initiation, and initial circuit life span.
Conclusions: This project will examine the differences in outcomes of CRRT in PICUs in specific patient and treatment groups and will be used to design future interventional studies. We will also aim to establish a platform for a multicenter registry study in Japanese PICUs, considering the current lack of such a platform.
