Clinical Scorecard: Automated Self-Adjusting Subcutaneous Insulin Algorithm for Inpatients: A Three-Year Observational Study on Glycemic Control
At a Glance
Category
Detail
Condition
Inpatient hyperglycemia management in patients who are NPO, on enteral tube feedings (TF), or total parenteral nutrition (TPN)
Key Mechanisms
Automated self-adjusting subcutaneous rapid-acting insulin algorithm (SQIA) integrated into EMR, titrating insulin dose every 4 hours based on point-of-care glucose measurements
Target Population
Adult inpatients who are NPO, on continuous TF, or on continuous TPN with hyperglycemia
Care Setting
Hospital inpatient setting with electronic medical record (EMR) system
Key Highlights
SQIA significantly reduces hypoglycemia (<70 mg/dL) and severe hyperglycemia (>250 mg/dL) compared to conventional insulin (CI) orders.
SQIA reduces physician insulin order burden by more than 12-fold compared to CI.
SQIA maintains glucose control effectively even in patients receiving glucocorticoids, including high-dose regimens.
Guideline-Based Recommendations
Diagnosis
Use point-of-care glucose measurements every 4 hours to monitor inpatient glycemic status.
Management
Employ basal-bolus insulin regimens for inpatients who are NPO or receiving TF or TPN as recommended by ADA and Endocrinology Society guidelines.
Utilize the SQIA embedded in the EMR to automate rapid-acting insulin dose adjustments every 4 hours based on glucose values.
Initial insulin dose entry is required; subsequent dosing is calculated automatically by the SQIA.
Monitoring & Follow-up
Perform q4h point-of-care glucose testing to guide insulin dose adjustments.
Nursing staff enter glucose values into the EMR calculator at each insulin administration time.
Risks
Hypoglycemia and severe hyperglycemia are risks with insulin therapy; SQIA reduces these risks compared to conventional insulin orders.
Insulin stacking risk mitigated by using rapid-acting insulin every 4 hours.
Patient & Prescribing Data
4310 hospitalizations involving patients who are NPO or on TF or TPN
Patients managed with SQIA had lower rates of hypoglycemia (0.65% vs 1.10%) and severe hyperglycemia (5.40% vs 6.65%) compared to conventional insulin; glucocorticoid-treated patients showed particularly improved control with SQIA.
Clinical Best Practices
Integrate insulin dosing algorithms into the EMR to reduce physician order burden and improve glycemic control.
Use rapid-acting insulin administered every 4 hours with automated dose titration to avoid insulin stacking and hypoglycemia.
Continuously update and improve insulin algorithms based on clinical data and nursing workflow feedback.
Ensure consistent q4h glucose monitoring and timely data entry by nursing staff to optimize algorithm performance.
