Area of Science:

  • Medical Science
  • Genetics
  • Obstetrics

Background:

  • Down syndrome screening is a critical component of antenatal care.
  • Accurate knowledge among healthcare providers is essential for informed patient counseling.
  • Previous assessments of healthcare professional knowledge in this area are limited.

Purpose of the Study:

  • To evaluate the knowledge level of healthcare professionals regarding Down syndrome screening.
  • To identify specific areas of deficiency in understanding prenatal screening tests.
  • To inform the development of targeted educational interventions.

Main Methods:

  • A structured, questionnaire-based survey was administered.
  • 166 healthcare providers involved in antenatal care were targeted.

  • 140 completed surveys were analyzed, yielding an 83% response rate.

    • Main Results:

    • While awareness of screening test timing was high, knowledge of test performance (detection and screen-positive rates) was poor.
    • Only 16% of counselors offered screening to all women, with others selecting 'high-risk' individuals.
    • Fewer than 10% could accurately provide specific detection and screen-positive rates.

    Conclusions:

    • Knowledge regarding Down syndrome screening among antenatal care providers is inconsistent.
    • There is a clear need for enhanced professional education on prenatal screening.
    • Improving provider knowledge can lead to more effective and equitable screening practices.
