A quality initiative to improve recognition of fluid overload among pediatric ICU patients requiring continuous kidney replacement therapy: preliminary results

Abstract

Background: Initiation of continuous kidney replacement therapy (CKRT) greater than 20% fluid overload is associated with increased morbidity and mortality. We aimed to reduce the number of patients initiated on CKRT greater than 20% fluid overload by 50% in one year by implementation of a quality improvement initiative.

Methods: This is a prospective quality improvement study set in a pediatric ICU of an urban children's hospital of patients initiated on CKRT over 2 years. The intervention included creation of an electronic health record order for daily calculation of net percent fluid overload, incorporation into daily rounds, and education programs tailored to physicians and bedside nursing. We measured adherence with the new order set, percent fluid overload at CKRT initiation, days on CKRT, timing of first nephrology consultation, and death prior to discharge.

Results: A total of 32% of patients were initiated on CKRT greater than 20% fluid overload pre-initiative and 9% post-initiative, a 72% reduction over 13 months. Patients initiated on CKRT greater than 20% fluid overload had median CKRT course of 8 (IQR 4-14) vs. 22 days (IQR 13.5-62).

Conclusion: Creating a system using EHR with education may reduce initiation of CKRT after development of severe fluid overload. A higher resolution version of the Graphical abstract is available as Supplementary information.
