ReviewWhat can a learning healthcare system teach us about improving outcomes?
This review describes the learning healthcare system paradigm, recent examples, and future directions. Patients, clinicians, and health systems frequently encounter decisions between available treatments, technologies, and healthcare delivery methods with little or no evidence about the comparative effectiveness and safety of the available options. Learning healthcare systems endeavor to recognize such knowledge gaps, integrate comparative effectiveness research - including clinical trials - into clinical care to address the knowledge gaps, and seamlessly implement the results into practice to improve care and patient outcomes. ⋯ Learning healthcare systems have the potential to answer questions of importance to patients, clinicians, and health system leaders, improve efficiency of healthcare delivery, and improve patient outcomes. Achieving this goal will require realignment of the culture around clinical care, institutional and federal investment, expanded stakeholder engagement, tailored ethical and regulatory guidance, and methodologic advances in information technology and biostatistics.

ReviewSepsis in patients hospitalized with coronavirus disease 2019: how often and how severe?
To discuss why severe COVID-19 should be considered sepsis and how co-infection and secondary infection can aggravate this condition and perpetuate organ dysfunction leading to high mortality rates. ⋯ The high mortality rates of critically ill patients with severe COVID-19 disease are not only related to the severity of patient disease but also to modifiable factors, such as the ICU strain, HAI incidence, and organizational aspects. Therefore, HAI prevention and the delivery of best evidence-based care for these patients to avoid additional damage is important. Quality improvement interventions might help in improving outcomes mainly in resource-limited settings.

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.

ReviewCoronavirus disease 2019 respiratory failure: what is the best supportive care for patients who require ICU admission?
Currently, there is no cure for SARS-CoV-2 infection, yet hospital mortality rates for COVID-19 have improved over the course of the pandemic and may be due in part to improved supportive care in the ICU. This review highlights the evidence for and against various ICU supportive therapies for the treatment of critically ill patients with COVID-19. ⋯ In general, the COVID-19 pandemic reaffirmed the benefits of standard supportive care for respiratory failure and in particular, recent advances in ARDS treatment. Prone ventilation of nonintubated patients, an approach that was adopted early in the pandemic, is associated with improvement in oxygenation, but its impact on clinical outcome remains unclear. Otherwise, prone mechanical ventilation and avoidance of excessive tidal volumes, conservative fluid management, antibiotic stewardship and early evaluation for extracorporeal membrane oxygenation (ECMO) -- basic tenants of severe respiratory infections and ARDS care -- remain at the core of management of patients with severe COVID-19.
