Patterns of syphilis testing in the elderly.

Area of Science:

• Geriatric Medicine
• Infectious Diseases
• Clinical Laboratory Science

Background:

• Syphilis remains a public health concern, particularly in vulnerable populations.
• Appropriate laboratory testing and follow-up are crucial for effective syphilis management.
• Elderly individuals may present with atypical symptoms, complicating diagnosis.

Purpose of the Study:

• To assess the frequency of inconsistent laboratory testing for syphilis in elderly patients within an acute care setting.
• To identify patterns of inappropriate syphilis test utilization and follow-up.

Main Methods:

• Retrospective review of medical records from an academic medical center.
• Inclusion criteria focused on elderly patients (≥60 years) with specific syphilis test and lumbar puncture combinations.
• Data abstraction included test chronology, results, and documentation of neurosyphilis signs and symptoms.

Main Results:

• A significant number of elderly patients (51) with positive syphilis tests lacked adequate follow-up.
• Cerebrospinal fluid syphilis testing was performed inappropriately in 43 patients without positive blood tests or clinical indications.
• Most evaluations demonstrated inadequate diagnostic workups for syphilis.

Conclusions:

• The observed pattern of syphilis testing suggests it was often performed routinely, not for specific clinical indications.
• Inconsistent testing practices limit the public health benefit and individual patient well-being.
• Improved guidelines and physician education are needed for appropriate syphilis testing in the elderly.
