In healthcare, informed consent is a crucial process that involves thoroughly communicating medical treatment options to patients, including benefits, risks, potential side effects, and alternatives. This process enables patients to make well-informed decisions about their care, ensuring they understand the implications of their choices before consenting to or refusing treatment.
The legal responsibilities of a nurse regarding informed consent include the following:

Area of Science:

  • Medical Ethics
  • Neurosurgery
  • Patient Safety

Background:

  • Informed consent is a cornerstone of medical ethics and law in the U.S.
  • The American Association of Neurological Surgeons Code of Ethics highlights medicolegal liability for inadequate informed consent.
  • There is a need for practical guidance on applying informed consent in neurosurgical practice.

Purpose of the Study:

  • Identify baseline patient recall and capacity for informed consent after neurosurgical discussions.
  • Describe interventions to enhance patient comprehension of medical information.
  • Elucidate the role of informed consent in neurosurgical malpractice litigation.

Main Methods:

  • Systematic review of PubMed, Embase, and Scopus databases.
  • Selection and full-text review of articles meeting inclusion criteria.
  • Analysis of study design, aims, populations, interventions, and outcomes related to informed consent in neurosurgery.

Main Results:

  • Baseline patient recall of treatment risks and alternatives was low and declined over time.
  • Cognitive impairment affects the capacity to provide informed consent.
  • Multimodal interventions (e.g., specialized forms, interactive websites, illustrations) improved patient knowledge.
  • Lack of informed consent is a frequent cause of malpractice litigation, especially in spine surgery.

Conclusions:

  • Improving informed consent requires addressing patient health literacy and understanding.
  • Clear communication using multiple modalities is essential for effective informed consent.
  • Determining patient capacity and viewing informed consent as an ongoing process are critical in clinical practice.
