Proficiency at Tick Identification by Pathologists and Clinicians Is Poor.

Area of Science:

• Medical Entomology
• Infectious Diseases
• Public Health

Background:

• Accurate tick identification is essential for administering appropriate antimicrobial prophylaxis for Lyme disease.
• The northeastern United States has the highest incidence of Lyme disease.
• Clinician proficiency in tick identification directly impacts patient care and disease prevention strategies.

Purpose of the Study:

• To assess the proficiency of clinicians in identifying various tick species.
• To evaluate the accuracy of tick identification in a high-incidence Lyme disease region.

Main Methods:

• A voluntary survey was conducted among clinicians.
• High-resolution photographs of different tick species were used to test identification skills.

Main Results:

• Only 35% of ticks were correctly identified overall.
• While 60% could identify a nonengorged adult blacklegged tick, only 34% correctly identified a partially engorged one.
• Classification accuracy was significantly lower for brown dog, American dog, and Lone Star ticks.

Conclusions:

• Clinician proficiency in identifying tick species, including those that transmit Lyme disease, is alarmingly poor.
• This lack of proficiency may hinder the timely and correct administration of prophylaxis, potentially affecting patient outcomes.
