The outbreak of the coronavirus disease 2019 (COVID-19) and its rapid global spread have created unprecedented challenges to health care systems. Significant and sustained efforts have focused on mobilization of personal protective equipment, intensive care beds, and medical equipment, while substantially less attention has focused on preserving the psychological health of the medical workforce tasked with addressing the challenges of the pandemic. And yet, similar to battlefield conditions, health care workers are being confronted with ongoing uncertainty about resources, capacities, and risks; as well as exposure to suffering, death, and threats to their own safety. These conditions are engendering high levels of fear and anxiety in the short term, and place individuals at risk for persistent stress exposure syndromes, subclinical mental health symptoms, and professional burnout in the long term. Given the potentially wide-ranging mental health impact of COVID-19, protecting health care workers from adverse psychological effects of the pandemic is critical. Therefore, we present an overview of the potential psychological stress responses to the COVID-19 crisis in medical providers and describe preemptive resilience-promoting strategies at the organizational and personal level. We then describe a rapidly deployable Psychological Resilience Intervention founded on a peer support model (Battle Buddies) developed by the United States Army. This intervention—the product of a multidisciplinary collaboration between the Departments of Anesthesiology and Psychiatry & Behavioral Sciences at the University of Minnesota Medical Center—also incorporates evidence-informed “stress inoculation” methods developed for managing psychological stress exposure in providers deployed to disasters. Our multilevel, resource-efficient, and scalable approach places 2 key tools directly in the hands of providers: (1) a peer support Battle Buddy; and (2) a designated mental health consultant who can facilitate training in stress inoculation methods, provide additional support, or coordinate referral for external professional consultation. In parallel, we have instituted a voluntary research data-collection component that will enable us to evaluate the intervention’s effectiveness while also identifying the most salient resilience factors for future iterations. It is our hope that these elements will provide guidance to other organizations seeking to protect the well-being of their medical workforce during the pandemic. Given the remarkable adaptability of human beings, we believe that, by promoting resilience, our diverse health care workforce can emerge from this monumental challenge with new skills, closer relationships, and greater confidence in the power of community.

The N-methyl-D-aspartate glutamate receptor antagonist ketamine has demonstrated rapid antidepressant effects in treatment-resistant depression (TRD). However, evaluation of ketamine's neurocognitive aspects in TRD has started to be explored. This study aims to (1) examine baseline neurocognitive performance and change in severity of depressive symptoms through six ketamine infusions, (2) examine the neurocognitive effects after completion of serial infusions and whether changes were associated to relapse to depression. Six IV infusions of 0.5 mg/Kg ketamine over 40 min were conducted on a Monday-Wednesday-Friday schedule during a 12-d period on 15 patients with TRD followed by a 4-wk observational period. Neurocognitive functioning was assessed using the CogState battery at baseline and at each follow-up visit. Tasks were designed to test attention, memory (working, visual, and verbal), speed of processing, and set shifting. The likelihood of response through six infusions was greater among depressed subjects with lower attention at baseline (F(1,13)=5.59, p=0.034). Significant improvement was found in scores of visual memory (F(4,33.82)=5.12, p=0.002), simple working memory (F(4, 24.85)=3.29, p=0.027) and complex working memory (F(4, 32.76)=4.18, p=0.008) after the last ketamine infusion. However, neurocognitive changes were accounted for by improvement in the severity of depressive symptom. The acute neurocognitive effect after completion of repeated infusions was not associated with the likelihood of subsequent relapse during follow-up. Our findings suggest a potential baseline neurocognitive predictor of ketamine response and the apparently lack of short-term neurocognitive impairment after completion of six ketamine infusions in TRD.
