ReviewAlgorithmic prognostication in critical care: a promising but unproven technology for supporting difficult decisions.
Patients, surrogate decision makers, and clinicians face weighty and urgent decisions under uncertainty in the ICU, which could be aided by risk prediction. Although emerging artificial intelligence/machine learning (AI/ML) algorithms could reduce uncertainty surrounding these life and death decisions, certain criteria must be met to ensure their bedside value. ⋯ Improved ICU prognostication, enabled by advanced ML/AI methods, offer a promising approach to inform difficult and urgent decisions under uncertainty. However, critical knowledge gaps around performance, equity, safety, and effectiveness must be filled and prospective, randomized testing of predictive interventions are still needed.

COVID-19 represents an unprecedented public health crisis caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The antiviral remdesivir is one component of treating COVID-19. Unfortunately, the trials evaluating remdesivir have reported mixed results, leading to uncertainty on when to use remdesivir. This review discusses the trials evaluating the efficacy of remdesivir for COVID-19 and other supporting data to help inform the role of remdesivir in patients with COVID-19. ⋯ The majority of trials evaluating remdesivir suggest that remdesivir is effective in the treatment of patients hospitalized with COVID-19. Although there may be a benefit in some subgroups more than others, there is insufficient data to make definitive statements about benefits or lack of benefits in particular groups. Remdesivir has demonstrated clinical benefits such as decreased time in the hospital, lower progression to mechanical ventilation, and decreased utilization of other hospital resources; it is unclear if it reduces mortality, but one randomized controlled trial suggested possible survival benefits. Based on the data available, remdesivir has been approved (or authorized for early use) in 48 countries.

If developed using rigorous methods and produced in a timely manner, clinical practice guidelines have the potential to improve patient outcomes. Although the COVID-19 pandemic has highlighted the challenges involved in generating reliable clinical guidance, it has also provided an opportunity to address these challenges. ⋯ We provide an example of how rapid and rigorous guidelines can be accomplished, even in the setting of a pandemic, capitalizing on expertise, large and dedicated teams, and focused scope. We highlight the benefits of multifaceted knowledge dissemination through multiple formats to ensure global dissemination and in order to maximize impact.

ReviewIs there a role for immune-enhancing therapies for acutely ill patients with coronavirus disease 2019?
Although the so-called cytokine storm has been early described and related to a dramatic evolution in severe COVID-19 patients, it soon became clear that those patients display clinical and biological evidence of an immunosuppressive state characterized, among other, by a profound lymphopenia. The negative role of this immune suppression on the outcome raises the question on immune therapies that might improve patient's condition. ⋯ In this article, we provide a review on active and passive immune boosting strategies that might help treating the most severe COVID-19 patients. We mainly focus on active strategies that include IL-7, thymosin-α, interferons, and vitamin D. Although some positive effects are described, they certainly warrant confirmation in large randomized controlled trials.

Critical care registries are synonymous with measurement of outcomes following critical illness. Their ability to provide longitudinal data to enable benchmarking of outcomes for comparison within units over time, and between units, both regionally and nationally is a key part of the evaluation of quality of care and ICU performance as well as a better understanding of case-mix. This review aims to summarize literature on outcome measures currently being reported in registries internationally, describe the current strengths and challenges with interpreting existing outcomes and highlight areas where registries may help improve implementation and interpretation of both existing and new outcome measures. ⋯ Digital registries could help overcome some of the current challenges with implementing and interpreting ICU outcome data through standardization of reporting and harmonization of data. In addition, ICU registries could be instrumental in enabling data for feedback as part of improvement in both patient-centred outcomes and in service outcomes; notably resource utilization and efficiency.
