Optimisation of intravenous fluid prescribing: framework for changing practice through education and audits

INTRODUCTION: Intravenous fluids are one of the most commonly prescribed drugs in the hospital setting and yet the practice continues to fall short of National Institute for Health and Care Excellence (NICE) guidelines, with significant gaps in staff knowledge exposing patients to heightened morbidity and mortality. AIM: Following the 2013 publishing of updated NICE guidelines on intravenous fluid prescribing, an intravenous fluid team was formed within the Royal Liverpool University Hospital (RLUH). Their role has been (and continues to be) to overhaul the culture of suboptimal intravenous fluid prescribing within the hospital and, ultimately, to improve patient outcomes. A framework to engender this change has been developed and is offered as an example to other Trusts within which improvement of guideline-compliant intravenous fluid prescribing remains stagnant. METHOD: There have been three principal stages of the project to this point which are best demonstrated in a chronological manner. The period of 2010–2014 allowed for assessment of the issue of intravenous fluid prescribing and analysis of its causes through serial audits and a staff-wide survey. From 2015, there has been implementation of several measures (educative, managerial, administrative and technological) within the hospital to foster reproducible and positive change with regards to intravenous fluid prescribing. Finally, between 2016 and 2017, three cycles of a rolling audit based on NICE guidelines have been completed to allow measurement of improvement in intravenous fluid prescribing practice. CONCLUSION: Results have demonstrated a significant improvement in the appropriateness of the intravenous maintenance and replacement fluids prescribed in the hospital since the March 2016 audit. Moreover, a 29-fold increase has been observed in the use of 4% dextrose/0.18% sodium chloride as maintenance fluid (gold standard as per NICE guidelines) since the staff-wide survey of 2015. Despite progress however, adherence to NICE guidelines remains below the recommended 100% and therefore further work remains to be done.
