This paper discusses the hospitalization of aviators at the Naval Regional Medical Center, San Diego, Ca. The areas covered include cancer, trauma, cardiac cases, alcoholics, and the effect of hospitalization on the flying status of aviators. The variety of diagnoses accumulated in 2 years was suprising. Further follow-up of cardiac cases must be pursued, especially post-coronary artery bypass. Alcoholism as a diagnosis in hospitalized patients may be a larger problem than elicited in this series. Hopefully this paper will not be just a statistical study. We should think of prevention and care to decrease the number of aviators who have their wings clipped due to medical problems.
