During the coronavirus disease 2019 pandemic, crisis changes in clinical care increased rates of delirium in the intensive care unit (ICU). Deep sedation, unfamiliar environments with visitor restrictions, and such factors due to high workload and health system strain contributed to the occurrence of delirium doubling in the ICU. As the pandemic wanes, health care systems and ICU leadership must emphasize post-pandemic recovery, integrating lessons learned about delirium management, evidence-based care, and family involvement.

Delirium is the most common manifestation of brain dysfunction in critically ill patients. In the intensive care unit (ICU), duration of delirium is independently predictive of excess death, length of stay, cost of care, and acquired dementia. There are numerous neurotransmitter/functional and/or injury-causing hypotheses rather than a unifying mechanism for delirium.

Unlabelled: The ICU Liberation (ABCDEF) Bundle can help to improve care and outcomes for ICU patients, but bundle implementation is far from universal. Understanding how ICU organizational characteristics influence bundle implementation could inform quality improvement efforts. We surveyed all hospitals in Michigan with adult ICUs to determine whether organizational characteristics were associated with bundle implementation and to determine the level of agreement between ICU physician and nurse leaders around ICU organizational characteristics and bundle implementation.

The novel coronavirus, SARS-CoV-2-causing Coronavirus Disease 19 (COVID-19), emerged as a public health threat in December 2019 and was declared a pandemic by the World Health Organization in March 2020. Delirium, a dangerous untoward prognostic development, serves as a barometer of systemic injury in critical illness. The early reports of 25% encephalopathy from China are likely a gross underestimation, which we know occurs whenever delirium is not monitored with a valid tool.

Delirium, one of the most common manifestations of acute brain dysfunction, is a serious complication in patients receiving care throughout the hospital and a strong predictor of worse outcome. Although delirium monitoring is advocated in numerous evidence-based guidelines as part of routine clinical care, it is still not widely and consistently performed at the bedside in different patient care settings. In a debate on delirium monitoring in hospitalized patients at the 7th American Delirium Society meeting in Nashville, Tennessee, June 2017, areas related to the feasibility, acceptability, and effectiveness of routine delirium monitoring of hospitalized patients were identified, and arguments both for (pro) and against (con) the practice were presented.

Although growing evidence supports the safety and effectiveness of the ABCDEF bundle (A, assess, prevent, and manage pain; B, both spontaneous awakening and spontaneous breathing trials; C, choice of analgesic and sedation; D, delirium: assess, prevent, and manage; E, early mobility and exercise; and F, family engagement and empowerment), intensive care unit providers often struggle with how to reliably and consistently incorporate this interprofessional, evidence-based intervention into everyday clinical practice. Recently, the Society of Critical Care Medicine completed the ICU Liberation ABCDEF Bundle Improvement Collaborative, a 20-month, nationwide, multicenter quality improvement initiative that formalized dissemination and implementation strategies and tracked key performance metrics to overcome barriers to ABCDEF bundle adoption. The purpose of this article is to discuss some of the most challenging implementation issues that Collaborative teams experienced, and to provide some practical advice from leading experts on ways to overcome these barriers.

Background: There are conflicting data on the effects of antipsychotic medications on delirium in patients in the intensive care unit (ICU).

Methods: In a randomized, double-blind, placebo-controlled trial, we assigned patients with acute respiratory failure or shock and hypoactive or hyperactive delirium to receive intravenous boluses of haloperidol (maximum dose, 20 mg daily), ziprasidone (maximum dose, 40 mg daily), or placebo. The volume and dose of a trial drug or placebo was halved or doubled at 12-hour intervals on the basis of the presence or absence of delirium, as detected with the use of the Confusion Assessment Method for the ICU, and of side effects of the intervention.
