Psychosurgery

Psychosurgery, the surgical alteration or permanent removal of brain tissue to alleviate severe psychological conditions, stands as one of the most radical and controversial treatments in the history of mental health care. Its development and application have evolved significantly, marked by dramatic shifts in scientific understanding and ethical perspectives.

Summary

Neurosurgical consultations and CT scans for head injuries are often unnecessary. Implementing the Canadian CT Head Rule could improve patient care and reduce costs.

Area of Science:

  • Neurosurgery
  • Emergency Medicine
  • Radiology

Background:

  • Neurosurgical consultations and computed tomography (CT) scans are critical for assessing patients with potential head or spine injuries.
  • Clinical judgment of deterioration risk guides the necessity of these interventions.
  • The University of California Davis Medical Center (UCDMC) sought to evaluate the appropriateness of neurosurgical (NSG) consultations and CT usage.

Purpose of the Study:

  • To determine the proportion of NSG consultations at UCDMC that are appropriately indicated.
  • To compare the utilization of CT scans in head-injured patients with the Canadian CT Head Rule (CCHR).

Main Methods:

  • A prospective study evaluated 99 emergency consultations at UCDMC.
  • Consultations were categorized into head injury, spine injury, and others.
  • Appropriateness was assessed based on the likelihood of clinically significant injuries; CT scans in head injury cases were evaluated using the CCHR.

Main Results:

  • Out of 99 consultations, 69 were appropriate, 23 inappropriate, and 7 unclassified.
  • For head-injured patients, 10 out of 32 (31.2%) received CT scans that were deemed inappropriate.
  • NSG receives 3-4 consultations daily, with a significant portion being of questionable necessity.

Conclusions:

  • A substantial number of NSG consultations and CT scans for head injuries at UCDMC are not clinically necessary.
  • Adoption of the CCHR could optimize patient care, reduce healthcare expenses, and minimize radiation exposure.
  • Standardizing decision-making tools like the CCHR is recommended for neurosurgical consultations.
