Informed consent for screening sigmoidoscopy in a Veterans Administration population

Area of Science:

• Medical Ethics
• Patient Education
• Gastroenterology

Background:

• Informed consent is a cornerstone of ethical medical practice.
• Current methods of obtaining informed consent may not effectively communicate necessary information to patients.
• Emphasis on documentation may overshadow genuine patient understanding.

Purpose of the Study:

• To evaluate patient comprehension of information provided during the informed consent process for sigmoidoscopy.
• To test whether current consent methods adequately convey essential data.
• To determine if patients desire the information physicians believe they should provide.

Main Methods:

• Fifty-nine male patients undergoing screening sigmoidoscopy were interviewed pre- and post-procedure.
• Chi-squared analysis assessed the impact of ethnicity, education, and prior experience on consent components.
• Interviews focused on understanding indications, risks, benefits, and alternatives.

Main Results:

• Many patients could not articulate the procedure's indication or define key terms like "polyp."
• Comprehension of potential complications (bleeding, perforation) and alternatives was notably low.
• Despite signing consent forms, few patients read them, and most felt they had sufficient information, even without understanding risks or identifying their endoscopist.

Conclusions:

• Patients in this study often did not meet traditional standards for informed consent regarding sigmoidoscopy.
• Despite inadequate understanding, most patients reported satisfaction with the information received and did not seek further clarification.
• This phenomenon persisted across diverse demographic groups, suggesting systemic issues in the informed consent process.
