Background: Subphenotypes have been identified in patients with sepsis and ARDS and are associated with different outcomes and responses to therapies.

Research Question: Can unique subphenotypes be identified among critically ill patients with COVID-19?

Study Design And Methods: Using data from a multicenter cohort study that enrolled critically ill patients with COVID-19 from 67 hospitals across the United States, we randomly divided centers into discovery and replication cohorts. We used latent class analysis independently in each cohort to identify subphenotypes based on clinical and laboratory variables. We then analyzed the associations of subphenotypes with 28-day mortality.

Results: Latent class analysis identified four subphenotypes (SP) with consistent characteristics across the discovery (45 centers; n = 2,188) and replication (22 centers; n = 1,112) cohorts. SP1 was characterized by shock, acidemia, and multiorgan dysfunction, including acute kidney injury treated with renal replacement therapy. SP2 was characterized by high C-reactive protein, early need for mechanical ventilation, and the highest rate of ARDS. SP3 showed the highest burden of chronic diseases, whereas SP4 demonstrated limited chronic disease burden and mild physiologic abnormalities. Twenty-eight-day mortality in the discovery cohort ranged from 20.6% (SP4) to 52.9% (SP1). Mortality across subphenotypes remained different after adjustment for demographics, comorbidities, organ dysfunction and illness severity, regional and hospital factors. Compared with SP4, the relative risks were as follows: SP1, 1.67 (95% CI, 1.36-2.03); SP2, 1.39 (95% CI, 1.17-1.65); and SP3, 1.39 (95% CI, 1.15-1.67). Findings were similar in the replication cohort.

Interpretation: We identified four subphenotypes of COVID-19 critical illness with distinct patterns of clinical and laboratory characteristics, comorbidity burden, and mortality.

Top Ten Tips Palliative Care Clinicians Should Know About Opioid Use Disorder.

J Palliat Med 2020 09 21;23(9):1250-1256. Epub 2020 Jul 21.

Division of Geriatrics and Palliative Care, Department of Medicine, Veterans Affairs Boston Healthcare System, Boston, Massachusetts, USA.

Since the prevalence of substance use disorders, and opioid use disorder (OUD) specifically, remains high and represents a public health crisis, it is critical that palliative care (PC) providers have a broad understanding of this class of chronic, yet treatable, diseases. Conceptualizing stigma associated with OUD, treatment modalities available, and educational opportunities are key factors in providing patient-centered care. A solid foundation of knowledge about OUD in the setting of serious illness is also crucial as PC providers often recommend or prescribe opioids for symptom management in patients who also have OUD. Furthermore, the PC interdisciplinary team is particularly well poised to care for patients suffering from OUD due to the inherently holistic approach already present in the specialty of PC. This article offers PC teams a framework for understanding the diagnosis and treatment of OUD, methods for performing risk stratification and monitoring, and an overview of opportunities to enhance our care of PC patients with OUD.
