Family practice residents decreased laboratory test utilization over three years of training. High utilizers remained high, while variation decreased, indicating improved uniformity in test ordering practices.

Area of Science:

  • Medical Education
  • Health Services Research
  • Family Medicine

Background:

  • Laboratory test utilization is a key component of ambulatory care.
  • Understanding resident test ordering patterns is crucial for optimizing healthcare resource allocation.
  • Variability in test utilization can impact diagnostic accuracy and healthcare costs.

Purpose of the Study:

  • To analyze the changes in laboratory test utilization among family practice residents throughout their three-year training.
  • To identify trends in test ordering practices from postgraduate year I (PGY I) to PGY III.
  • To assess the consistency and variation in test utilization across residents and training years.

Main Methods:

  • Longitudinal study tracking laboratory test utilization.

  • Inclusion of nineteen family practice residents across four training classes.
  • Data collection over the entire three-year residency program.

    • Main Results:

    • A significant decrease in laboratory test utilization was observed in the third year compared to PGY I and PGY II.
    • While most residents reduced test use, some low utilizers increased their utilization between the first and second year.
    • Substantial variation in test utilization persisted throughout training, though the degree of variation decreased over time.

    Conclusions:

    • Laboratory test utilization declines as residents progress through training.
    • Individual resident test ordering habits show persistence, with high utilizers remaining high.
    • Training leads to greater uniformity in test utilization, suggesting a convergence of practice patterns.
