AIM

Reduce critical hypoglycemia (blood glucose <40 mg/dL) among hospitalized patients within two years.

BACKGROUND

On average, one of every three hospitalized patients requires insulin therapy to control blood glucose during their stay, which places them at risk of hypoglycemia. Evidence shows hypoglycemia can lead to infections and other complications, prolonged lengths of stay, increased readmission rates and sentinel events. Preventing hypoglycemia is imperative to patient safety and quality of care.

AdventHealth Waterman, a 269-bed community hospital in central Florida, performed a review of all-cause inpatient hypoglycemic events using data over a one-year period, April 1, 2016 - March 31, 2017. The results indicated an opportunity to implement clinical practice changes and other strategies to reduce critical hypoglycemia.

METHODS

We conducted standardized root cause analysis on all blood glucose values <40 mg/dL. Results identified four areas for targeted interventions: (1) failure to follow policy, (2) stacking insulin, (3) wrong insulin dose, and (4) failure to adjust insulin. An interdisciplinary team was tasked with designing and implementing appropriate clinical practice changes and quality improvement initiatives.

CONCLUSIONS

A comparison of pre-intervention data (April 1, 2016 - March 31, 2017) to post-intervention data (April 1, 2018 - March 31, 2019) revealed we reduced all-cause critical hypoglycemia <40 mg/dL by 16.9% of patient days (from 0.65% to 0.54%). The most significant improvements were associated with four areas of targeted interventions: (1) failure to follow policy, (2) stacking insulin, (3) wrong insulin dose, and (4) failure to adjust insulin. We attribute our success to clinical practice changes and quality improvement initiatives coupled with the implementation of a technology-enabled approach to intravenous infusion and subcutaneous basal-bolus insulin dosing using an eGlycemic Management System®.

We recommend that any hospital seeking to achieve best practice and clinical excellence in glycemic management perform a similar root cause analysis of critical hypoglycemic events, define the most appropriate targeted interventions, and utilize education, accountability, workflow and policy measures to achieve their goals.
