Insights
Diagnosing congenital syphilis (CS) in newborns is challenging due to data gaps and misinterpretation of case definitions. Improving data sharing and physician education is crucial for accurate CS classification and reporting.
Area of Science:
- Pediatrics
- Infectious Diseases
- Public Health
Background:
- Congenital syphilis (CS) diagnosis relies on maternal history and infant findings.
- Physician and health department classification of CS cases can be difficult, especially during epidemics.
Purpose of the Study:
- To describe challenges in classifying congenital syphilis (CS) cases.
- To identify reasons for discordance between physician and epidemiologist classifications of CS.
Main Methods:
- Review of records for infants identified as potential CS cases.
- Epidemiological review to determine concordance and discordance in classification.
- Analysis of reasons for misclassification.
Main Results:
- 126 infants had confirmed congenital syphilis.
- 17 cases showed discordant classifications between physicians and epidemiologists.
- Misclassification stemmed from data gaps (physician or health department) and misinterpretation of the CS case definition.
Conclusions:
- Inaccurate congenital syphilis (CS) diagnosis and reporting occur due to data limitations and definition misinterpretation.
- Enhanced data sharing between healthcare providers and health departments is recommended.
- Improved physician education on CS case definitions is necessary for accurate diagnosis and reporting.
Abstract:
The diagnosis of congenital syphilis (CS) in newborns can only be made through a review of the mothers' testing and treatment history and through the infants' clinical and laboratory findings. We describe difficulties in the classification of CS by physicians and the health department during a recent syphilis epidemic. The records of infants identified as potential cases of CS by laboratory testing, discharge diagnosis, or health department records were reviewed by epidemiologists. The reasons for concordance and discordance in classification between the physician and the epidemiologist were determined. Congenital syphilis was identified in 126 infants. Seventeen cases were discordant and 12 cases concordant but the physician's classification was for incorrect reasons. Misclassification occurred because physicians lacked data known to the health department (n=7), health departments lacked data known to the physician (n=1), and physicians misinterpreted the case definition for CS (n=21). Suggestions for improving the diagnosis and reporting of CS are included.
