New data will fuel debate about sliding scale insulin for inpatient hyperglycemia in patients withOUT type 1 diabetes. Guidelines continue to recommend basal or basal-bolus insulin instead of sliding scale to reduce HYPERglycemia. But this is driven by limited evidence. And many clinicians haven't embraced basal-bolus, since it can increase HYPOglycemia risk and is labor intensive.
Now TWO studies in non-ICU patients add real-world perspective. Both generally support a role for sliding scale alone, especially when admission glucose is under 180 mg/dL. And one suggests that basal-bolus may not be a preferred regimen. These data are limited. But they reinforce current practice of individualizing hyperglycemia treatment, based on the patient's current blood glucose, home management, hypoglycemia risk, etc.
Keep aiming for a blood glucose under 180 mg/dL for most floor and ICU patients, while avoiding HYPOglycemia. But use a higher goal in some cases, such as under 250 mg/dL for an asymptomatic floor patient with severe kidney disease. Start with sliding scale for many non-ICU patients, especially if they're well managed on 1 or 2 non-insulin medications at home or don't have diabetes.
If hyperglycemia persists for 24 to 48 hours, add a once-daily basal insulin dose, such as 0.15 to 0.25 units/kg. Or consider starting with basal plus sliding scale for patients well managed at home on insulin or several non-insulin medications. Save basal-bolus plus sliding scale for patients with good enteral intake who use this regimen at home, or have uncontrolled glucose on higher insulin doses, such as more than 0.6 units/kg/day.
Ensure your protocol provides clear instructions for basal-bolus plus sliding scale and review steps with nursing to avoid errors. Before discharge, generally restart home diabetes medications, stop inpatient insulin regimens and document the plan. Also verify follow-up within 1 to 2 weeks if diabetes regimens are changed.
