Summary
Physician comfort in diagnosing smallpox is low, with only 17% feeling confident. Enhanced bioterrorism education is needed to improve early detection and management of potential smallpox outbreaks.
Area of Science:
- Public Health
- Infectious Diseases
- Medical Education
Background:
- Recent bioterrorism events raise concerns about intentional smallpox release.
- Early diagnosis of smallpox is critical for controlling transmission.
Purpose of the Study:
- To assess primary care and emergency physicians' diagnostic capabilities for smallpox.
- To identify knowledge gaps in smallpox diagnosis and management among physicians.
Main Methods:
- Survey of 178 physicians at an urban academic medical center in Dec 2002-Jan 2003.
- Questionnaire assessed comfort, differential diagnosis knowledge (vs. chickenpox), and photographic interpretation.
- Responses analyzed using perceived comfort, differential diagnosis, and picture scores.
Main Results:
- 95% of physicians believed more bioterrorism education is necessary.
- Only 17% of physicians reported comfort in diagnosing smallpox.
- While most recognized images, only 36% correctly answered differential diagnosis questions.
Conclusions:
- Physicians exhibit significant deficits in smallpox diagnostic skills and bioterrorism preparedness.
- Training strategies should leverage physicians' self-identified knowledge gaps in rash diagnosis.
- Improving diagnostic accuracy is crucial for effective public health response to bioterrorism threats.
