Improving Isotonic Maintenance Intravenous Fluid Use at a Tertiary Children's Hospital

Closing the Fluid Gap: Improving Isotonic Maintenance Intravenous Fluid Use in a Community Hospital Network

Introduction

The American Academy of Pediatrics recommends using isotonic intravenous fluids (IVF) for maintenance needs to decrease the risk of hyponatremia. We conducted a quality improvement project to increase the use of isotonic maintenance IVF in pediatric patients admitted to three sites in a community hospital network to >85% within 12 months.

Methods

We used improvement methodology to identify causes of continued hypotonic fluid use, which involved provider behavior and systems factors. We implemented interventions to address these factors including: (1) education; (2) clinical decision support; and (3) stocking automated medication dispensing systems with isotonic IVF. We compared isotonic IVF use before and after interventions in all admitted patients aged 28 days to 18 years who received maintenance IVFs at the rate of at least 10 mL/hour. We excluded admissions of patients with active chronic medical conditions like diabetic ketoacidosis. Balancing measures were the occurrence of adverse events from hypo- or hypernatremia. Data were analyzed using Laney P' statistical process control charts.

Results

Isotonic IVF use among patients requiring maintenance fluids at all three sites surpassed the goal of >85% within 12 months. There were no reports of hypo- or hypernatremia or other adverse outcomes related to the use of isotonic IVF.

Conclusion

A combination of interventions aimed at provider behavior and systems factors was critical to successfully adopting the American Academy of Pediatrics guideline regarding the use of maintenance isotonic IVF in hospitalized children.

Fluid management of the critically Ill child

PURPOSE OF REVIEW

This review summarizes current literature pertaining to fluid management for critically ill children. It includes an overview on crystalloid fluid used throughout the critical illness course, management of fluid output and complications with fluid overload.

RECENT FINDINGS

Observational paediatric studies and adult randomized trials show mixed results regarding risk of mortality and kidney injury with 0.9% saline and crystalloid fluid. A recent adult randomized trial suggests that a fluid restrictive strategy may be well tolerated in critically ill adults with septic shock, but further randomized trials are needed in paediatrics. Fluid overload has been associated with increased morbidity and mortality. Trials exploring ways to decrease fluid accumulation must be done in paediatrics.

SUMMARY

Additional high-quality studies are needed to precisely define the type, timing and rate of intravenous fluid critically ill children should receive throughout their clinical illness course.

Fluid and electrolyte management: increasing the knowledge of House Officers using an interactive eLearning tool

BACKGROUND

Interactive case-based tutorials represent a well-established method of improving House Officer learning. There has been little research on how tutorials of this kind can be improved, and whether their use changes practice.

AIM

Our study aims to assess whether our eLearning tutorial on IV fluid and electrolyte prescribing improves the underlying knowledge base and confidence of participating House Officers, with regards to fluid and electrolyte balance physiology and prescribing.

METHOD

An interactive eLearning module with core information on fluid and electrolyte prescribing and associated cases with questions and answers was created and distributed to participating House Officers in the 2019-2020 cohort nationwide. Participants were asked to complete pre-eLearning and post-eLearning questionnaires as well as a feedback survey to assess the efficacy of the module.

RESULTS

Forty-nine House Officers completed the eLearning module and associated questionnaires. A majority of participants (69.3%) reported their previous teaching on fluid and electrolyte management as "very poor", "poor" or "mediocre". The average score for the pre-eLearning knowledge test was 75%, compared to a score of 97% for the post-eLearning knowledge test, resulting in a 22% increase in correct answers (p < 0.001). We found an increase of 53% in feeling "confident" or "very confident" in assessing and managing fluid requirements, and an increase of 57.1% in feeling "confident" or "very confident" in managing electrolyte requirements after undertaking the eLearning module.

CONCLUSION

An interactive eLearning tutorial with real-world applications provides an effective, low-cost intervention that can improve confidence and skill in prescribing IV fluids.

Efficacy and Safety of Isotonic and Hypotonic Intravenous Maintenance Fluids in Hospitalised Children: A Systematic Review and Meta-Analysis of Randomised Controlled Trials

Hyponatraemia is a known complication in hospitalised children receiving maintenance intravenous fluid. Several studies have been published to investigate the efficacy and safety of intravenous fluids in children. However, there is still an ongoing debate regarding the ideal solution to be used in the paediatric population. Therefore, the aim of this meta-analysis was to investigate the safety and efficacy of administering isotonic versus hypotonic intravenous maintenance fluid in hospitalised children. An extensive search was undertaken on PubMed, Web of Science, Scopus, ScienceDirect, Google Scholar and Cochrane Library on 28 December 2020. Only randomised controlled trials (RCTs) were included. We used the random-effects model for all analyses. Risk ratio (RR) and mean difference with 95% confidence intervals (CIs) were used for dichotomous and continuous outcomes, respectively. The quality of each study was assessed using the Joanna Briggs Institute critical appraisal tool for RCTs. This study is registered with PROSPERO (CRD42021229067). Twenty-two RCTs with a total of 3795 participants were included. The studies encompassed surgical and medical patients admitted to intensive care unit as well as to general wards. We found that hypotonic fluid significantly increases the risk of hyponatremia at both ≤24 h (RR 0.34; 95% CI: 0.26–0.43, p < 0.00001) and >24 h (RR 0.48; 95% CI: 0.36–0.64, p < 0.00001). Isotonic fluid increases the risk of hypernatraemia at ≤24 h (RR 2.15; 95% CI: 1.24–3.73, p = 0.006). The prevalence of hyponatraemia was also higher in the hypotonic group at both ≤24 h (5.7% vs. 23.3%) and >24 h (6.0% vs. 26.3%). There was no statistically significant difference in the risk of developing adverse outcomes between the two groups. Mean serum and urine sodium as well as serum osmolality/osmolarity was lower in the hypotonic group. Isotonic solution is protective against the development of hyponatraemia while hypotonic solution increases the risk of hyponatraemia.
