From the Guidelines
For a T2DM patient presenting to the ED with hyperglycemia of 336 mg/dL after experiencing a rash, insulin therapy should be initiated to manage glucose levels, with a starting total daily requirement estimated at 0.3-0.4 units/kg/d, as significant hyperglycemia requires prompt treatment pending additional diagnostic workup 1. The patient's presentation with a rash and hyperglycemia necessitates a thorough evaluation to determine the underlying cause of the elevated glucose levels.
- The rash could be indicative of an allergic reaction, infection, or a diabetes-related skin condition, and thus, requires careful assessment.
- Initial management should focus on lowering the glucose levels with insulin therapy, as recommended for significant hyperglycemia 1.
- The estimated starting total daily insulin requirement can be calculated at 0.3-0.4 units/kg/d, with half of the daily requirements given as prandial coverage and the other half as a once-daily long-acting insulin homolog 1.
- Frequent glucose monitoring, at least 4 times daily, or the use of a continuous glucose monitor is essential to adjust the insulin doses accordingly and to prevent hypoglycemia.
- It is also crucial to assess for other symptoms of hyperglycemia, such as polyuria, polydipsia, and to evaluate for ketones to rule out diabetic ketoacidosis.
- After stabilization, the patient's outpatient diabetes regimen should be reviewed and adjusted as necessary, potentially increasing oral medications or basal insulin doses.
- Early endocrinology consultation is highly recommended for patients with T2DM, especially when initiating or managing insulin therapy, to provide education on skills like responding to hypoglycemia and monitoring for DKA 1.

From the Research
Management of Hyperglycemia in T2DM Patients
- The presence of hyperglycemia in T2DM patients increases mortality and morbidity associated with the primary condition, as well as related hospital admission rates and costs 2.
- Optimization of hyperglycemia management in the emergency department (ED) may improve clinical outcomes, but more clinical trial data on the outcomes and cost-effectiveness of various management strategies or protocols are needed 2.
- There is no direct evidence in the provided studies on the specific management of glucose in a T2DM patient presenting to the ED with hyperglycemia of 336 after experiencing a rash.
Considerations for T2DM Patients with Hyperglycemia
- T2DM is a chronic disease characterized by hyperglycemia and insulin resistance, and metformin is considered the first-line therapy for T2DM 3.
- The pathophysiology of T2DM involves defective insulin secretion by pancreatic β-cells and the inability of insulin-sensitive tissues to respond appropriately to insulin 4.
- Diabetic ketoacidosis (DKA) is a known complication of T2DM, and patients with T2DM have significantly higher odds of having septic shock and increased healthcare utilization costs compared to patients with type 1 diabetes mellitus (T1DM) 5.
Medications and Hyperglycemia Management
- Sodium glucose co-transporter 2 inhibitors (SGLT2i) have been associated with an increased risk of DKA in patients with T2DM compared to other antihyperglycemic agents (AHAs) 6.
- The choice of medication for hyperglycemia management in T2DM patients should be based on individual patient characteristics and medical history, and careful monitoring of glucose levels is necessary to prevent complications such as DKA.
