Interventions and strategies for enhancing the consent process in neurosurgery. A systematic review of the literature.

Abstract

Background: The informed consent process in neurosurgery aims to support patient autonomy and provide comprehensive information for decision-making. However, gaps in communication and understanding between patients and surgeons persist, that need to be addressed. This systematic review examined the interventions and strategies which to enhance the process of consent in neurosurgery.

Methods: A comprehensive search of databases and relevant sources to identify relevant studies for inclusion. Systematic review of prospective and retrospective studies that assess the effect of interventions which improve the consent process. Data collection and analysis involved independent reviewers assessing eligibility, study quality, and risk of bias. Findings from the included studies were used to write the review.

Main results: The reviewed identified seven studies notably revealed an educational and interactive consent process involving strategies like booklets, videos, multiple interviews, and interactive websites showed improvements in patient knowledge. Recall of risks decreased over time, and factors like age, education, and timing of consent influenced recall.

Authors’ conclusions: To maximise informed consent, neurosurgeons should consider various strategies. Tailoring communication-based on patient's health literacy and treatment knowledge, involving their support system, and using a bullet-point consent form is essential. Utilising multiple modalities like verbal, static, and dynamic visuals improve information retention. Creative and memorable visual aids enhance comprehension. Allowing time for questions and team approach is superior.
