Summary

Efficient use of low-osmolar contrast media is crucial due to cost. A study found 13% of contrast material was wasted, with significant differences between hospital types and imaging suites.

Area of Science:

  • Radiology
  • Medical Imaging
  • Healthcare Administration

Background:

  • Low-osmolar contrast media (LOCM) are increasingly used, necessitating efficient utilization due to their higher cost compared to conventional agents.
  • Understanding patterns of intravascular contrast media usage and waste is vital for cost containment and resource optimization in radiology departments.

Purpose of the Study:

  • To quantify the amount of intravascular contrast media used and discarded in three distinct radiology departments.
  • To identify specific areas within radiology departments where contrast media waste is most prevalent.
  • To compare contrast media wastage between a community hospital and university-affiliated teaching hospitals.

Main Methods:

  • A prospective study was conducted over one month in the summer of 1987 across three hospitals in southwestern Ontario.
  • Intravascular contrast media usage and discarded amounts were meticulously measured in each participating department.
  • Data collection focused on differentiating waste across various imaging modalities, particularly angiography and computed tomography.

Main Results:

  • Overall, 13% of all contrast material utilized by the three hospitals was discarded.
  • The angiography suite emerged as the primary site of contrast media waste.
  • Minimal wastage was observed in computed tomography examinations.
  • The community hospital demonstrated significantly less contrast media waste compared to the two university-affiliated teaching hospitals.

Conclusions:

  • A notable portion of contrast media is wasted, suggesting that some level of wastage may be unavoidable.
  • Strategies such as multidose dispensing systems and varied bottle sizes could potentially mitigate contrast media waste.
  • Radiology departments must actively monitor and analyze their specific contrast media usage patterns to identify and address waste reduction opportunities.
