Implementing ultrasonography (US) for blunt abdominal trauma (BAT) significantly reduces healthcare costs. This diagnostic imaging approach led to substantial savings by decreasing the need for more expensive procedures like computed tomography (CT) and diagnostic peritoneal lavage (DPL).

Area of Science:

  • Medical Imaging
  • Trauma Surgery
  • Health Economics

Background:

  • Blunt abdominal trauma (BAT) evaluation in the US increasingly incorporates ultrasonography (US).
  • Assessing the financial impact of US in BAT management is crucial for resource allocation in trauma centers.

Purpose of the Study:

  • To evaluate the cost-effectiveness of using ultrasonography (US) in the assessment of blunt abdominal trauma (BAT) patients.
  • To compare the procedural costs and utilization rates of US, computed tomography (CT), and diagnostic peritoneal lavage (DPL) before and after US implementation.

Main Methods:

  • A retrospective analysis comparing BAT patients from two 6-month periods: pre-US implementation (1993) and post-US implementation (1995).
  • Tabulation of US, CT, and DPL procedures performed, along with their associated hospital expenditures.

  • Statistical analysis using t-tests and chi-squared tests to determine significance (P < 0.05).

    • Main Results:

    • Total procedural costs for BAT evaluation decreased from $254,316 in 1993 to $168,501 in 1995, a savings of $171,630 annually.
    • Cost per patient evaluated significantly reduced by 43% from $285.75 in 1993 to $163.12 in 1995 (P < 0.05).
    • US utilization increased significantly, leading to an eight-fold reduction in DPL use and a two-fold reduction in CT use.

    Conclusions:

    • Effective integration of ultrasonography in blunt abdominal trauma protocols leads to significant cost savings.
    • The shift towards US in BAT evaluation reduces reliance on more invasive and costly diagnostic methods.
    • Implementing US is a cost-effective strategy for managing blunt abdominal trauma patients in major trauma centers.
