Safe insulin use in the hospital setting

Reduction of Insulin Related Preventable Severe Hypoglycemic Events in Hospitalized Children

OBJECTIVE

Insulin is a commonly used, high-risk medication in the inpatient setting. Incorrect insulin administration can lead to preventable hypoglycemic events, which are a significant morbidity in inpatient diabetes care. The goal of this intervention was to decrease preventable insulin-related hypoglycemic events in an inpatient setting in a tertiary care pediatric hospital.

METHODS

Methods included the institution of several interventions such as nursing and physician education, electronic medical record order sets, electronic communication note templates, and the development of new care guidelines.

RESULTS

After the institution of multiple interventions, the rate of preventable hypoglycemic events decreased from 1.4 preventable events per 100 insulin days to 0.4 preventable events per 100 insulin days.

CONCLUSIONS

Through the use of a multi-interventional approach with oversight of a multidisciplinary insulin safety committee, a sustained decreased rate of severe preventable hypoglycemic events in hospitalized pediatric patients receiving insulin was achieved.

Review of insulin therapy and pen use in hospitalized patients

OBJECTIVE

Hyperglycemia is common among hospitalized patients, affecting approximately 40% of patients at the time of hospital admission, despite the fact that 1 in every 8 patients has no previous diagnosis of diabetes. Hyperglycemia has been associated with poor patient outcomes, including higher rates of morbidity and mortality across a range of conditions. This review discusses options for the effective management of hyperglycemia with a focus on the use of disposable insulin pens in the hospital.

METHODS

Literature, including guidelines for hospital management of hyperglycemia, and information regarding methods of insulin administration were reviewed.

RESULTS

Appropriate glucose control via administration of insulin within hospitals has been acknowledged as an important goal and is consistent with achieving patient safety. Insulin may be administered subcutaneously using a pen or vial and syringe or infused intravenously. Levels of patient and provider satisfaction are higher with pen administration than with vial and syringe. Insulin pens have many safety and convenience features including enhanced dose accuracy and autocover/autoshield pen needles.

CONCLUSION

Use of insulin pens instead of vials and syringes can provide several advantages for hospitalized patients, including greater satisfaction among them and health care providers, improved safety, and reduced costs. These advantages can continue following patient discharge.

Glycemic management in the inpatient setting

Hyperglycemia occurs frequently in hospitalized patients and affects patient outcomes, including mortality, inpatient complications, hospital length of stay, and overall hospital costs. Various degrees of glycemic control have been studied and consensus statements from the American Diabetes Association/American Association of Clinical Endocrinologists and The Endocrine Society recommend a target blood glucose range of 140 to 180 mg/dL in most hospitalized patients. Insulin is the preferred modality for treating all hospitalized patients with hyperglycemia, as it is adaptable to changing patient physiology over the course of hospitalization. Critically ill patients should receive intravenous insulin infusion, and all noncritically ill patients with hyperglycemia (individuals with and without diabetes) should be managed using a subcutaneous insulin algorithm with basal, nutritional, and correctional dose components. Hypoglycemia remains a limiting factor to achieving optimal glycemic targets. Similar to hyperglycemia, hypoglycemia is an independent risk factor for poor outcomes in hospitalized patients. Improvement in glycemic control throughout the hospital includes efforts from all health care providers. Institutions can encourage safe insulin use by using insulin algorithms, preprinted order sets, and hypoglycemia protocols, as well as by supporting patient and health care provider education.
