Calcium-Scoring CT ScanA calcium-scoring CT scan, also known as coronary artery calcium (CAC) scan, detects calcium deposits in the coronary arteries. This test assesses the risk of coronary artery disease (CAD), which can lead to cardiovascular events such as angina, heart failure, and sudden cardiac arrest.A calcium-scoring CT scan is generally recommended for individuals at intermediate risk of CAD without symptoms. It includes:Men aged 40-75 and women aged 50-75: Especially those with a...

Area of Science:

  • Ophthalmology
  • Neonatal care
  • Medical informatics

Background:

  • Retinopathy of prematurity (ROP) screening is crucial but burdensome due to frequent examinations.
  • Current screening methods may lead to missed treatment-requiring disease (TR-ROP), impacting infants, families, and healthcare systems.
  • The potential of precision risk models to optimize ROP screening frequency without compromising safety remains unexplored.

Purpose of the Study:

  • To develop and externally validate an interpretable risk model for predicting 2-week TR-ROP risk.
  • To integrate gestational age (GA), postmenstrual age (PMA), and vascular severity (VSS or P-score) into the risk model.
  • To estimate the impact of this model on ROP screening frequency.

Main Methods:

  • Diagnostic study utilizing i-ROP consortium and SUNDROP datasets for training, validation, and external validation.
  • Development of a risk model incorporating GA, PMA, and vascular severity (VSS or P-score).
  • Retrospective simulation to assess the proportion of examinations deferrable while maintaining 100% sensitivity for TR-ROP detection.

Main Results:

  • The risk model integrating vascular severity demonstrated improved discrimination compared to GA alone.
  • A decision threshold achieved 100% sensitivity for TR-ROP prediction with moderate specificity (63-73%).
  • Simulated risk-based scheduling reduced examinations by 28-39% across datasets without missing TR-ROP cases; P-score substitution maintained model performance.

Conclusions:

  • A validated, clinically adaptable risk model offers individualized, visit-level TR-ROP risk assessment.
  • This model has the potential to enhance screening efficiency by reducing unnecessary examinations while ensuring safety.
  • Prospective evaluation is necessary before routine clinical implementation of this risk-based screening approach.
