Quantitative and qualitative evaluation of volume of low osmolality contrast medium needed for routine helical abdominal CT.

AJR. American journal of roentgenology·2001

Nearly half of low-risk patients chose safer, nonionic contrast media despite higher costs. This highlights the importance of informed consent regarding contrast material risks and options for all patients.

Area of Science:

  • Radiology
  • Medical Imaging
  • Patient Safety

Background:

  • Nonionic, low-osmolar contrast media offer reduced risks of adverse reactions compared to conventional ionic agents.
  • Increased costs of nonionic contrast media have led to selective use, primarily in high-risk patients.
  • The decision-making process for contrast media selection in low-risk patients is not well understood.

Purpose of the Study:

  • To evaluate the choice of contrast media by low-risk outpatients when offered a choice between nonionic and ionic agents.
  • To determine the proportion of low-risk patients who would opt for the lower-risk, higher-cost nonionic contrast material.
  • To assess patient perspectives on informed consent regarding contrast media risks.

Main Methods:

  • A prospective study involving 250 outpatients undergoing contrast-enhanced computed tomography.

  • Exclusion of patients at high risk for contrast reactions, leaving 162 eligible low-risk participants.
  • Informed consent process detailing risks of ionic contrast and benefits/costs of nonionic contrast media.

    • Main Results:

    • 48% of the 162 low-risk patients surveyed selected nonionic contrast media.
    • A significant majority (63%) believed all patients should be informed about contrast material risks and nonionic availability.
    • Patient preference indicates a willingness to consider lower-risk options when informed.

    Conclusions:

    • Informed consent is crucial for low-risk patients regarding the comparative risks of ionic and nonionic contrast materials.
    • Providing patients with choices and clear information empowers them to make informed decisions about their imaging procedures.
    • The findings support the routine practice of offering informed consent for contrast media selection, regardless of patient risk stratification.
