Informed consent -- why are its goals imperfectly realized?

B R Cassileth, R V Zupkis, K Sutton-Smith

    The New England Journal of Medicine

    Summary

    Many cancer patients struggle to recall crucial information from consent forms. Legalistic language and cursory reading contribute to poor understanding of treatment risks and procedures.

    Area of Science:

    • Medical Ethics
    • Patient Communication
    • Oncology

    Background:

    • Informed consent is a cornerstone of ethical medical practice.
    • Effective patient comprehension of treatment details is vital for decision-making.

    Purpose of the Study:

    • To investigate factors influencing cancer patients' recall of information presented in consent forms and oral explanations.
    • To identify reasons for inadequate patient understanding of consent materials.

    Main Methods:

    • A study involving 200 cancer patients within one day of signing consent forms for chemotherapy, radiation therapy, or surgery.
    • Patients completed a recall test on consent information and a questionnaire on their perceptions of the forms.

    Main Results:

    • Only 60% understood the procedure's purpose and nature; 55% could name a major risk.
    • Inadequate recall was linked to lower education levels, medical status, and perceived carefulness in reading forms.
    • Only 40% reported reading consent forms carefully; many believed forms primarily protected physicians.

    Conclusions:

    • Cancer patients exhibit significant deficits in recalling essential information from consent processes.
    • The legalistic nature of consent forms may inadvertently promote superficial reading and hinder comprehension.
    • Improving patient understanding requires addressing factors beyond mere provision of information, potentially through clearer language and patient-centered communication strategies.
