Insulin-dependent diabetes and serious trauma

Area of Science:

• Trauma Care
• Endocrinology
• Diabetology

Background:

• Diabetes mellitus (DM) complicates trauma outcomes due to hyperglycemia.
• Both acute injury and DM can elevate blood glucose levels, negatively impacting patient recovery.
• Understanding the differential impact of DM types on trauma mortality is crucial for targeted interventions.

Purpose of the Study:

• To investigate the impact of insulin-dependent DM (IDDM) and non-insulin-dependent DM (NIDDM) on mortality in severe trauma patients without brain injury.
• To analyze the association between different types of DM and patient survival after significant traumatic events.

Main Methods:

• Utilized data from the National Trauma Data Bank (NTDB) version 7.0 for patients with severe traumatic injury (ISS >9).
• Excluded patients with missing data, under 10 years old, severe brain injury (AIS head >3), dead on arrival, or AIS 6.
• Employed logistic regression to model the relationship between DM, IDDM, NIDDM, and mortality.

Main Results:

• Analyzed 166,103 trauma patients; overall mortality was higher in DM patients (7.6%) compared to non-DM patients (4.4%).
• Mortality rates were 9.9% for IDDM and 6.7% for NIDDM.
• DM increased mortality significantly only in patients in their forties. Logistic regression identified DM (AOR 1.14) and IDDM (AOR 1.46) as mortality predictors, while NIDDM (AOR 1.02) was not.

Conclusions:

• Diabetes mellitus is a predictor of increased mortality in severe trauma patients.
• The elevated mortality risk was specifically linked to insulin-dependent DM (IDDM), not non-insulin-dependent DM (NIDDM).
• IDDM patients with severe trauma represent a unique group requiring focused management of hyperglycemia and insulin therapy for improved outcomes.
