Physician test ordering showed minimal variation between two medical services at a Veterans Affairs hospital. Further research into physician behavior can explain healthcare utilization differences.

Area of Science:

  • Health Services Research
  • Medical Education
  • Veterans Affairs Healthcare

Background:

  • Physician test-ordering behavior can influence healthcare costs and patient outcomes.
  • Understanding variations in diagnostic testing is crucial for healthcare quality improvement.
  • Veterans Affairs Medical Centers provide a unique setting for studying healthcare delivery due to standardized practices.

Purpose of the Study:

  • To compare physician test-ordering behavior between two independent medical services at a Veterans Administration hospital.
  • To identify any significant differences in diagnostic testing practices.
  • To explore the implications of physician behavior for small-area analysis of healthcare utilization.

Main Methods:

  • Retrospective chart review of 119 patients admitted over a 5-month period.

  • Data abstraction focused on diagnostic testing processes and patient care outcomes.
  • Comparison of test-ordering patterns between two randomly assigned medical school services.

    • Main Results:

    • A statistically significant difference was found in abdominal film utilization (12% on one service vs. 0% on the other).
    • Overall, diagnostic testing practices showed limited variation between the two services.
    • No significant differences were noted in patient care outcomes related to testing variations.

    Conclusions:

    • Physician behavior at a single facility may offer insights into broader healthcare utilization variations.
    • Further investigation into practice patterns is needed to understand diagnostic test ordering.
    • The study highlights the need for analyzing physician decision-making in healthcare delivery.
