Hypoglycemia and Glucagon01:15

Hypoglycemia and Glucagon

353
Without prolonged fasting, healthy individuals maintain blood glucose levels above 3.5 mM due to a well-adapted neuroendocrine counterregulatory system that effectively prevents acute hypoglycemia, a potentially life-threatening condition. The primary clinical scenarios for hypoglycemia encompass diabetes treatment, inappropriate production of endogenous insulin or insulin-like substances by tumors, and the use of glucose-lowering agents in non-diabetic individuals. Notably, hypoglycemia in the...

Diabetes: Management and Pharmacotherapy

412
The therapy for diabetes aims to alleviate hyperglycemia-related symptoms, prevent acute metabolic decompensation, and reduce chronic end-organ complications. Glycemic control is evaluated through short-term (self-monitoring, continuous glucose monitoring) and long-term (A1c, fructosamine) metrics, enabling near real-time tracking of blood glucose levels and reflecting glycemic control over specific time frames.
Insulin remains the cornerstone of treatment for most patients with type 1 and many...

Oral Hypoglycemic Agents: Glinides01:06

Oral Hypoglycemic Agents: Glinides

274
Repaglinide (Prandin) and Nateglinide (Starlix), known as glinides, are oral insulin secretagogues that stimulate insulin release from pancreatic β cells by closing the ATP-sensitive potassium channels (KATP channel). Repaglinide controls insulin release from pancreatic β cells by managing potassium efflux. It shares two binding sites with sulfonylureas and also has a unique site, indicating overlapping mechanisms of action. With a rapid onset and a 4-7 hour duration, it effectively...

Insulin: Dosing Regimen and Adverse Effects01:16

Insulin: Dosing Regimen and Adverse Effects

271
Insulin-replacement therapy usually includes both long-acting insulin (basal) and short-acting insulin (to cater to postprandial needs). In a diverse group of type 1 diabetes patients, the average daily insulin dose is typically 0.5-0.7 units/kg body weight. However, obese patients and pubertal adolescents may need more due to insulin resistance.
The basal dose constitutes about 40%-50% of the total daily dose, with the rest as premeal insulin. The mealtime insulin dose should mirror...

Dipeptidyl Peptidase 4 Inhibitors01:23

Dipeptidyl Peptidase 4 Inhibitors

271
Dipeptidyl peptidase 4 (DPP-4) is a serine protease widely distributed in the body. It's involved in the inactivation of GLP-1 and GIP hormones, which are crucial for insulin regulation. DPP-4 inhibitors, such as sitagliptin (Januvia), saxagliptin (Onglyza), linagliptin (Tradjenta), alogliptin (Nesina), and vildagliptin (Galvus), help increase the proportion of active GLP-1, enhancing insulin secretion. These inhibitors work by competitively binding to DPP-4. This binding causes a...

Area of Science:

  • Internal Medicine
  • Quality Improvement Science
  • Endocrinology

Background:

  • Hypoglycemia is a common adverse event in hospitalized patients.
  • Inpatient insulin management involves basal, prandial, and correction components.
  • Effective strategies are needed to reduce hypoglycemia incidence.

Purpose of the Study:

  • To implement and evaluate three quality improvement (QI) interventions aimed at reducing hypoglycemia in hospitalized patients.
  • To assess the impact of these interventions on different aspects of inpatient insulin management.

Main Methods:

  • A comparative study was conducted in a tertiary hospital, analyzing nonobstetrics patients aged 19 years and older.
  • Three QI interventions were implemented: weight-based insulin guidance in EHR, carbohydrate-limited diet, and increased correction insulin threshold.
  • Incidence of hypoglycemia was compared before and after intervention implementation.

Main Results:

  • Significant reductions in hypoglycemia were observed with prandial (P = .02) and correction insulin (P < .001).
  • No significant decrease in basal insulin-associated hypoglycemia was found (P = .25).
  • A subgroup analysis showed a significant decrease in hypoglycemia for patients with type 2 diabetes (P = .005), with an overall reduction in glucose readings within the target range (P < .0001).

Conclusions:

  • A multipronged QI approach targeting specific insulin management components effectively reduced inpatient hypoglycemic events.
  • These interventions demonstrate a successful strategy for improving patient safety and glycemic control in the hospital setting.
