Occurrence of Advance Care Planning and Hospital Course in Patients Admitted for Coronavirus Disease 2019 (COVID-19) During the Pandemic.

INTRODUCTION: The Coronavirus Disease 2019 (COVID-19) pandemic highlighted the importance of understanding patients' goals, values, and medical care preferences given the high morbidity and mortality. We aimed to examine rates of advance care planning (ACP) documentation along with hospital course differences in the absence or presence of ACP among hospitalized patients with COVID-19. METHODS: This retrospective cohort study was performed at a single tertiary academic medical center. All adults admitted between March 1, 2020, and June 30, 2020, for COVID-19 were included. Demographics, ACP documentation rates, presence of ACP forms, palliative care consultation (PCC) rates, code status, and hospital outcome data were collected. Data were analyzed with multivariable analysis to identify predictors of ACP documentation. RESULTS: Among 356 patients (mean age 60.0, 153 (43%) female), 97 (27.2%) had documented ACP and 20 (5.6%) had completed ACP forms. In patients with documented ACP, 52.4% (n = 55) de-escalated care to do-not-resuscitate (DNR)-limited or comfort measures. PCC occurred rarely (<8%), but 78% (n = 21) of those consulted de-escalated care. Being admitted to the intensive care unit (ICU) (OR = 11.1, 95% CI = 5.9-21.1), mechanical intubation (OR = 15.8, 95% CI = 7.4-32.1), and discharge location other than home (OR = 11.3, 95% CI = 5.7-22.7) were associated with ACP documentation. CONCLUSIONS: This study found low ACP documentation and PCC rates in patients admitted for COVID-19. PCC and completion of ACP were associated with higher rates of care de-escalation. These results support the need for pro-active ACP and PCC for patients admitted for serious illnesses, like COVID-19, to improve goal-informed care.

Patient Experiences With Ambulatory Telehealth in Neurology: Results of a Mixed-Methods Study.

OBJECTIVE: To assess patient experiences with rapid implementation of ambulatory telehealth during the coronavirus disease 2019 (COVID-19) pandemic. METHODS: A mixed-methods study was performed to characterize the patients' experience with neurology telehealth visits during the first 8 weeks of the COVID-19 response. Consecutive patients who completed a telehealth visit were contacted by telephone. Assenting patients completed a survey quantifying satisfaction with the visit followed by a semistructured telephone interview. Qualitative data were analyzed using the principles of thematic analysis. RESULTS: A total of 2,280 telehealth visits were performed, and 753 patients (33%) were reached for postvisit feedback. Of these, 47% of visits were by video and 53% by telephone. Satisfaction was high, with 77% of patients reporting that all needs were met, although only 51% would consider telehealth in the future. Qualitative themes were constructed, suggesting that positive patient experiences were associated not only with the elimination of commute time and associated costs but also with a positive physician interaction. Negative patient experiences were associated with the inability to complete the neurologic examination. Overall, patients tended to view telehealth as a tool that should augment, and not replace, in-person visits. CONCLUSION: In ambulatory telehealth, patients valued convenience, safety, and physician relationship. Barriers were observed but can be addressed.

Gene Expression Profiling and Functional Characterization of Macrophages in Response to Circulatory Microparticles Produced during Trypanosoma cruzi Infection and Chagas Disease.

BACKGROUND: Chronic inflammation and oxidative stress are hallmarks of chagasic cardiomyopathy (CCM). In this study, we determined if microparticles (MPs) generated during Trypanosoma cruzi (Tc) infection carry the host's signature of the inflammatory/oxidative state and provide information regarding the progression of clinical disease. METHODS: MPs were harvested from supernatants of human peripheral blood mononuclear cells in vitro incubated with Tc (control: LPS treated), plasma of seropositive humans with a clinically asymptomatic (CA) or symptomatic (CS) disease state (vs. normal/healthy [NH] controls), and plasma of mice immunized with a protective vaccine before challenge infection (control: unvaccinated/infected). Macrophages (mφs) were incubated with MPs, and we probed the gene expression profile using the inflammatory signaling cascade and cytokine/chemokine arrays, phenotypic markers of mφ activation by flow cytometry, cytokine profile by means of an ELISA and Bioplex assay, and oxidative/nitrosative stress and mitotoxicity by means of colorimetric and fluorometric assays. RESULTS: Tc- and LPS-induced MPs stimulated proliferation, inflammatory gene expression profile, and nitric oxide (∙NO) release in human THP-1 mφs. LPS-MPs were more immunostimulatory than Tc-MPs. Endothelial cells, T lymphocytes, and mφs were the major source of MPs shed in the plasma of chagasic humans and experimentally infected mice. The CS and CA (vs. NH) MPs elicited >2-fold increase in NO and mitochondrial oxidative stress in THP-1 mφs; however, CS (vs. CA) MPs elicited a more pronounced and disease-state-specific inflammatory gene expression profile (IKBKB, NR3C1, and TIRAP vs. CCR4, EGR2, and CCL3), cytokine release (IL-2 + IFN-γ > GCSF), and surface markers of mφ activation (CD14 and CD16). The circulatory MPs of nonvaccinated/infected mice induced 7.5-fold and 40% increases in ∙NO and IFN-γ production, respectively, while these responses were abolished when RAW264.7 mφs were incubated with circulatory MPs of vaccinated/infected mice. CONCLUSION: Circulating MPs reflect in vivo levels of an oxidative, nitrosative, and inflammatory state, and have potential utility in evaluating disease severity and the efficacy of vaccines and drug therapies against CCM.
