Military Aviators with Inflammatory Bowel Diseases Continued Flying

Area of Science:

• Aerospace Medicine
• Gastroenterology
• Military Health

Background:

• Military aviators face unique challenges with Inflammatory Bowel Disease (IBD) diagnosis during service.
• Current guidelines suggest restricted flying, but potential risks require further investigation.
• Long-term outcomes for aviators with IBD are not well-documented.

Purpose of the Study:

• To evaluate the long-term safety and operational flying capabilities of military aviators diagnosed with IBD.
• To assess the impact of IBD on flight qualification and safety in a military aviation context.

Main Methods:

• A prospective observational study of Israeli Air Force (IAF) aviators diagnosed with IBD over 23 years.
• Primary endpoint: qualification and safety for continued operational flying post-IBD diagnosis.
• Data collected on diagnosis, treatment, grounding periods, and flight status.

Main Results:

• 16 male aviators (average age 27) with Crohn's disease (CD) or ulcerative colitis (UC) were followed for an average of 130 months.
• 50% of aviators experienced temporary grounding (mean 177 days), with most periods being short-term and reversible.
• All aviators continued flying under monitoring, with no documented compromise in abilities or sudden incapacitation events.

Conclusions:

• Military aviators with IBD can safely continue flying operations, even with treatment or temporary grounding.
• Findings support current recommendations for allowing flight in aviators with IBD in stable remission.
• No severe disabling flares or incapacitation occurred, indicating manageable risks.
