Intravenous Access in Gastrointestinal Hemorrhage: A Multidisciplinary Quality Improvement Initiative Led by Emergency Department Nurses and Internal Medicine Physicians

Increasing optimal coagulation factor dosing in the paediatric emergency department: Update to a quality improvement study

INTRODUCTION

Prompt, appropriate coagulation factor replacement according to injury and bleeding severity in persons with haemophilia is required to prevent acute and long-term complications.

AIMS

Increase proportion of persons with haemophilia A (HA) and B (HB) treated appropriately for an acute injury and bleeding episode at a tertiary children's emergency department (ED) from 65% to 85% and sustain for one year. Secondary aim: increase time interval between patient ED encounters with out-of-range factor dosing.

METHODS

Utilizing quality improvement methodology and plan-do-study-analyze cycles, ED encounters for individuals with HA/HB receiving coagulation factor replacement for injuries were audited for in-range coagulation factor dosing. Goal factor dose defined as 50% correction for minor bleeds and 100% correction for major bleeds. Optimal dosing range defined as 90%-120% of the calculated goal dose to account for vial size variability. Interventions targeted communication via the EMR problem list and optimization of physician education.

RESULTS

Our previous publication demonstrated 33.3% of ED encounters with out-of-range factor replacement. Following several interventions, the cumulative rate of encounters with out-of-range dosing decreased to 18%. Overall, there was an increase in the mean percent of encounters receiving optimal factor dosing for both HA/HB compared to baseline (82.2% vs. 71.1%), though this was not a statistically significant difference.

CONCLUSION

Despite implementation of multiple interventions, out-of-range factor dosing continues to occur. Our team plans to reinstate simulation center education for ED staff and continue education efforts of pharmacists and hematology trainees with the goal of further reducing out-of-range dosing in our ED.

Evaluation of Peripheral Administration of 10% Calcium Chloride in a Retrospective, Single-Center Electronic Health Record Cohort

BACKGROUND

Calcium chloride is commonly used in emergency departments in the treatment of a variety of emergencies. Historically, administration via central venous catheters has been preferred owing to its high osmolarity and vesicant properties. Although preferred, central access may not always be available in time-sensitive, emergent situations leading to many instances of peripheral administration. The objective of this analysis was to evaluate the charted safety of peripheral venous administration of 10% calcium chloride.

METHODS

A single-center retrospective chart review was performed in patients who received 10% calcium chloride in the adult emergency department evaluating for the incidence of infusion-related adverse events. Patients were excluded if they were less than 18 years of age or had a lack of catheter documentation during 10% calcium chloride administration or if the 10% calcium chloride was documented as given through a central venous catheter.

RESULTS

A total of 72 administrations were evaluated. Patients were predominantly male (67%), with a median age of 55 years and body mass index of 29.2. The primary outcome demonstrated that 4 infusion-related adverse events occurred (6%) with grade 1 (n = 1) and grade 0 (n = 3) documented incidence of infusion-related adverse events. None of the documented incidence of infusion-related adverse events resulted in permanent tissue injury, and all patients had conservative management.

DISCUSSION

This study demonstrated that administration of 10% calcium chloride via peripheral venous catheters may be feasible and seemed to carry a low incidence of documented complications. Further prospective studies are needed to confirm study observations.
