Establishing a chorionic villus sampling program using a continuous improvement model enhanced patient outcomes and provided valuable data on pregnancy complications. Quality control was key to this successful implementation.

Area of Science:

  • Medical Genetics
  • Maternal-Fetal Medicine
  • Quality Improvement Science

Background:

  • Chorionic villus sampling (CVS) is a crucial prenatal diagnostic tool.
  • Establishing a new CVS program requires robust quality control and continuous improvement.
  • Vanderbilt University Medical Center (VUMC) initiated a CVS program to enhance prenatal care.

Purpose of the Study:

  • To detail VUMC's experience in establishing a CVS program.
  • To emphasize the role of quality control and continuous improvement in early CVS cases.
  • To analyze outcomes and complications in the first 1000 CVS procedures.

Main Methods:

  • Implementation of a continuous improvement model.
  • Utilization of a multidisciplinary team approach.

  • Establishment of a quality assurance process and a computerized database for data analysis.

    • Main Results:

    • Achieved 98.5% follow-up for initial symptoms post-CVS.
    • Obtained 93% pregnancy follow-up, including birth data.
    • Demonstrated improved processes and outcomes for patients, personnel, and providers.

    Conclusions:

    • A continuous improvement model positively impacted CVS program processes and patient outcomes.
    • The program provided valuable data on spontaneous abortion rates, pregnancy outcomes, and limb abnormalities.
    • Recommendations were generated for personnel training and program enhancement.
