When the third degree is necessary: do pediatricians obtain enough information to detect patients at risk for HCM?

Area of Science:

• Cardiology
• Pediatrics
• Genetics

Background:

• Hypertrophic cardiomyopathy (HCM) is a significant genetic heart disease.
• Early identification of HCM risk factors in children is crucial for timely intervention.
• Family history is a primary tool for assessing genetic disease risk.

Purpose of the Study:

• To evaluate the completeness and regularity of family history data collection by pediatricians.
• To determine if pediatricians are gathering sufficient information to identify children at risk for HCM.
• To identify factors influencing the thoroughness of family history taking.

Main Methods:

• A survey was distributed to 326 general pediatricians.
• The survey assessed the inclusion of specific HCM risk factors and relatives in family histories.
• Physician demographics (gender, medical school origin) were collected.

Main Results:

• 98.2% of pediatricians take family histories, but only 51.2% update them regularly.
• Less than 30% include all five key HCM risk factors.
• Inclusion of second-degree relatives was limited (40.5%).
• Female physicians and foreign medical graduates reported more thorough histories.

Conclusions:

• Many pediatricians may not be collecting adequate family history data to identify HCM risks in children.
• Inconsistent updating and incomplete data collection pose challenges for pediatric HCM risk assessment.
• Further education and standardized protocols may be needed to improve family history practices.
