Richard McNeer, MD, Ph.D.

Dr. McNeer has perceived significant and fundamental gaps in the ability of the medical field to assess and monitor critically ill patients since he was a medical resident. During his more than ten years as a trauma anesthesiologist, Dr. McNeer has experienced firsthand the frenetic, noisy, and stressful environment that surrounds the attempts to save the lives of critically ill patients, as well as the alarm/listener fatigue (ALF) that accompanies this environment. From this exposure, he has focused on developing an effective way to detect ALF in caregivers (or patients), with an ultimate goal of being able to prevent ALF. Dr. McNeer currently emphasizes the study of ALF in a systematic and scientific way that uses psychoacoustics, technology and simulation The goal is to help resolve this pressing and much publicized patient safety issue, and to promote an environment in which clinicians are able to devote their clinical skills and knowledge to patient care without the unnecessary and deleterious stress that is currently generated in critical care settings due to the cacophonous auditory milieu. Completion of this research will have an immediate impact on management of the auditory environment in critical care settings.

Research Interests

  • Characterization and reduction of alarm/listener fatigue in critical care settings
  • Human factors in medical alarm design and function
  • Role of auditory evoked potentials in assessment of sedation and anesthetic depth
  • Hemodynamic monitoring of critically-ill patients
