A simplified endoscopy consent form, mailed with information sheets, significantly improves patient understanding and consent rates compared to traditional pre-procedure forms. This approach ensures patients are better informed before undergoing upper gastrointestinal endoscopy.

Area of Science:

  • Gastroenterology
  • Medical Education
  • Patient Safety

Background:

  • Informed consent for upper gastrointestinal endoscopy necessitates patient comprehension of the procedure's nature and purpose, with ample time for deliberation and questions.
  • Current standard consent processes may not adequately inform patients, potentially compromising the integrity of informed consent.

Purpose of the Study:

  • To evaluate the effectiveness of a simplified, pre-mailed endoscopy consent form in enhancing patient understanding and satisfaction.
  • To compare the readability and usability of a new consent form against the standard form.

Main Methods:

  • A prospective study involving 200 outpatients undergoing upper gastrointestinal endoscopy.
  • Patients completed questionnaires assessing satisfaction with information from referring doctors, standard information sheets, and endoscopists.

  • Two groups were compared: Group 1 (n=100) used a standard consent form pre-procedure; Group 2 (n=100) received a simplified consent form with information sheets, to be signed before arrival if no questions remained.

    • Main Results:

    • The simplified consent form was read by 95% and signed by 88% of patients before arrival, compared to 54% reading the standard form pre-procedure.
    • 84% of patients found the new form easier to read and understand than the standard form.
    • Referring doctors explained the indication and procedure clearly in 79% and 68% of cases, respectively, highlighting a need for improved pre-procedure communication.

    Conclusions:

    • A significant proportion of patients referred for endoscopy are inadequately informed about the procedure.
    • The simplified endoscopy consent form, sent proactively with information materials, is preferred by patients and enhances informed consent.
    • Implementing this revised consent process can improve patient understanding and safeguard against procedures performed without adequate informed consent.
