Customized Informed Consent in Neurosurgery Using Stereoscopic Visualization

Overview

This study explores the use of stereoscopic visualization as an adjunct to conventional informed consent in neurosurgery, aiming to enhance patient understanding of brain tumor surgery. The approach offers a personalized, cost-effective alternative to 3D printing and virtual reality, potentially improving patient comprehension without increasing anxiety.

Background

Informed consent is a critical, legally and ethically mandated process that ensures patients understand their specific anatomy, disease prognosis, and surgical risks, thereby respecting patient autonomy. Neurosurgical procedures are particularly complex, making patient education challenging. Traditional methods often fail to fully convey intricate anatomical details, leading to poor patient comprehension and increased anxiety. Emerging technologies like 3D printing and virtual reality have improved understanding but have limitations such as cost and complexity. Stereoscopic visualization, which provides depth perception through offset images, may offer a simpler, personalized tool to enhance informed consent discussions.

Data Highlights

The study was a randomized prospective trial conducted at Charité – Universitätsmedizin Berlin involving patients scheduled for brain tumor surgery between June 2018 and January 2019. Eligible patients were screened for stereopsis and randomized into two groups: one receiving conventional informed consent alone and the other receiving additional stereoscopic visualization of their own imaging. Exclusion criteria included cognitive or visual impairments. The study was ethically approved and registered (DRKS00014930).

Key Findings

• Stereoscopic visualization provides a personalized, three-dimensional view of patient-specific brain tumor anatomy during informed consent.
• This method is less expensive and easier to implement than 3D printing while still enhancing anatomical understanding.
• Use of stereoscopic imaging may improve patient comprehension without increasing anxiety, supporting better patient autonomy.
• Improved patient understanding through stereoscopic visualization can strengthen the patient-doctor relationship and potentially reduce litigation risk due to miscommunication.
• Prior studies have shown multimedia and interactive tools improve informed consent quality; stereoscopic visualization adds a novel personalized dimension.

Clinical Implications

Incorporating stereoscopic visualization into neurosurgical informed consent can enhance patient education by providing a clearer understanding of complex brain anatomy and surgical risks. This approach supports patient autonomy and may improve trust and satisfaction without adding significant cost or time burdens. Clinicians should consider adopting stereoscopic tools as a practical adjunct to traditional consent discussions.

Conclusion

Stereoscopic visualization represents a promising, cost-effective enhancement to conventional neurosurgical informed consent, improving patient comprehension and engagement. Further research may confirm its broader applicability and impact on clinical outcomes.
