The quality of the electrodiagnostic referral system and the electrodiagnostic patterns in a sample of Egyptian patients

Abstract

Background
Electrodiagnosis is a localizing, diagnostic, and prognostic tool for individuals with suspected neuromuscular diseases. In addition to detailed history taking and thorough clinical examination, correct execution and interpretation of these tests can provide vital insights into the underlying neuromuscular disorders and frequently guide the need for proper management decision. The request for an electrodiagnosis examination should include brief clinical information and a provisional clinical diagnosis; this enhances the efficient easy performance of the test. The current study aims to detect the pattern of neuromuscular diseases in the Alexandria Main University Hospital, Egypt, and to evaluate the quality of the referral system to the electrodiagnosis unit.

Results
The study included 371 patients, out of which, 65% were referred from the Governmental Specialized Medical Councils and the Neurosurgery department. Although sensory complaints were the main reason for referral, yet 28.8% of patients did not show any electrodiagnosis abnormality. A compatible referral note led to shorter test times and fewer electromyography needle insertions.

Conclusion
Disorders of the peripheral nerves are the most frequent neuromuscular diseases referred to the electrodiagnosis unit with carpal tunnel syndrome being the most common disorder. A compatible referral letter is necessary when requesting an electrodiagnosis test, to save the physician time and focus on targeted procedures.
