Providing clinicians with laboratory use and cost data significantly reduced their test requests and expenditures. This feedback loop influenced physician decision-making, leading to sustained changes in requesting patterns.

Area of Science:

  • Medical Laboratory Science
  • Health Economics
  • Clinical Decision-Making

Background:

  • Clinician test ordering significantly impacts healthcare costs.
  • Understanding factors influencing test ordering behavior is crucial for cost containment.

Purpose of the Study:

  • To assess if providing laboratory utilization and cost data to physicians alters their test ordering habits.
  • To evaluate the impact of data feedback on clinical chemistry and hematology test requests.

Main Methods:

  • A two-year study involving monthly feedback of clinical chemistry test use and expenditure data to three consultant physicians.
  • Two physicians served as controls, receiving no such data.
  • Requesting patterns for clinical chemistry and hematology were monitored.

Related Experiment Videos

Main Results:

  • One year of feedback resulted in significant decreases: 15% in clinical chemistry requests, 27% in tests, and 21% in revenue expenditure.
  • A 10% reduction in hematology tests per outpatient visit was observed.
  • These reductions remained consistent for six months after feedback ceased.

Conclusions:

  • Feedback of laboratory data effectively modifies clinician requesting behavior.
  • Informing clinicians about their laboratory utilization and associated costs influences their decision-making processes.
