Time Out: The Impact of Physician Burnout on Patient Care Quality and Safety in Perioperative Medicine.

Perioperative care delivery is a patient-centered, multidisciplinary process. It relies heavily on synchronized teamwork from a well-coordinated team. Perioperative physicians-surgeons and anesthesiologists-face enormous challenges in surgical care delivery due to changing work environments, post-COVID consequences, shift work disorder, value conflict, escalating demands, regulatory complexity, and financial uncertainties. Physician burnout in this working environment has become increasingly prevalent. It is not only harmful to physicians' health and well-being, but it also affects the quality and safety of patient care. Additionally, the economic costs associated with physician burnout are untenable due to the high turnover rate, high recruitment expenses, and potential early permanent exit from medical practice. In this deteriorating environment of unbalanced physician supply/demand, recognizing, managing, and preventing physician burnout may help preserve the system's most valuable asset and contribute to higher quality and safety of patient care. Leaders in government agencies, health care systems, and organizations must work together to re-engineer the health care system for better physicians and patient care.

Veiled Harm: Impacts of Microaggressions on Psychological Safety and Physician Burnout.

Microaggression is widespread in the health care industry and occurs in every health care delivery setting. It comes in many forms, from subtle to obvious, unconscious to conscious, and verbal to behavioral. Women and minority groups (eg, race/ethnicity, age, gender, sexual orientation) are often marginalized during medical training and subsequent clinical practice. These contribute to the development of psychologically unsafe working environments and widespread physician burnout. Physicians experiencing burnout who work in unsafe psychological environments impact the safety and quality of patient care. In turn, these conditions impose high costs on the health care system and organizations. Microaggressions and psychological unsafe work environments are intricately related and mutually enhanced. Therefore, addressing both simultaneously is a good business practice and a responsibility for any health care organization. Additionally, addressing them can reduce physician burnout, decrease physician turnover, and improve the quality of patient care. To counter microaggression and psychological unsafe, it takes conviction, initiative, and sustainable efforts from individuals, bystanders, organizations, and government agencies.

Ketamine-Associated Brain Changes: A Review of the Neuroimaging Literature.

Major depressive disorder (MDD) is one of the most prevalent conditions in psychiatry. Patients who do not respond to traditional monoaminergic antidepressant treatments have an especially difficult-to-treat type of MDD termed treatment-resistant depression. Subanesthetic doses of ketamine-a glutamatergic modulator-have shown great promise for rapidly treating patients with the most severe forms of depression. As such, ketamine represents a promising probe for understanding the pathophysiology of depression and treatment response. Through neuroimaging, ketamine's mechanism may be elucidated in humans. Here, we review 47 articles of ketamine's effects as revealed by neuroimaging studies. Some important brain areas emerge, especially the subgenual anterior cingulate cortex. Furthermore, ketamine may decrease the ability to self-monitor, may increase emotional blunting, and may increase activity in reward processing. Further studies are needed, however, to elucidate ketamine's mechanism of antidepressant action.

Odor Memory and Discrimination Covary as a Function of Delay between Encoding and Recall in Rats.

Nonassociative odor learning paradigms are often used to assess memory, social recognition and neuromodulation of olfactory pathways. We here use a modified object recognition paradigm to investigate how an important task parameter, delay between encoding and recall trials, affects the properties of this memory. We show that both memory for a previously investigated odorant and discrimination of a novel odorant decay with delay time and that rats can remember an odorant for up to 45min after a single trial encoding event. The number of odorants that can be encoded, as well as the specificity of the encoded memory, decrease with increased delay and also depend on stimulus concentration. Memory for an odorant and discrimination of a novel odorant decay at approximately the same rate, whereas the specificity of the formed memory decays faster than the memory itself. These results have important implications for the interpretation of behavioral data obtained with this paradigm.
