ABSTRACT

Introduction: Numerous inflammatory markers may serve a role in prognostication of patients hospitalized with COVID-19 infection. Early in the pandemic, our health system created an admission order set which included daily d-dimer, c-reactive protein (CRP), lactate dehydrogenase (LDH), and ferritin. Given more available outcomes data, limiting standing order of labs that do not affect daily management could result in significant cost savings to the health system without adverse patient outcomes. The purpose of this study was to determine ordering and utilization patterns of inflammatory markers by physicians caring for patients hospitalized with COVID-19 infection. Methods: An anonymous 10-question survey was distributed to 125 physicians (Infectious Disease, Hospitalist, Pulmonary and Critical Care faculty). Responses were tallied and values greater than 50% were identified as the majority of the surveyed group. Results: Of the 125 physicians surveyed, 77 (62%) responded. A total of 57.1% (44/77) of physicians reported ordering daily inflammatory markers for 3 - 10 days from admission. Another 31.2% (24/77) ordered markers until clinical improvement or hospital discharge. D-dimer was used for care decisions by 83.1% (64/77) of respondents; 93.8% (60/64) of those reported utilizing it in determining anticoagulation dose. CRP was used by 61% (47/77) of physicians to help identify a secondary infection or determine steroid dose or duration. LDH and ferritin were not used for management decisions by the majority of physicians. Inflammatory markers were not used routinely after isolation precautions had been discontinued, even when ongoing care required mechanical ventilation. Conclusions: Of the markers studied, both d-dimer and CRP were considered useful by most respondents. LDH and ferritin were used less frequently and were not considered as useful in guiding medical decision making. Discontinuation of standing daily LDH and ferritin orders is believed to have potential to result in cost savings to the health care system with no adverse patient outcomes.

ABSTRACT

INTRODUCTION: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2, aka COVID-19) virus has evolved into a World Health Organization-declared pandemic which has strained our regional critical care and hospital resources. METHODS: A Critical Care Task Force was established between Kansas City area intensive care units to allow for preparedness for potential surges by sharing of bed capacity both in the ICU and hospital, and ventilator capacity as well as weekly web-based meetings to share resource concerns and best practice. This Task Force also collected patient information to understand the dynamics of community impact and resource needs better. This effort allowed for compilation and dissemination of information regarding data that describe characteristics of patients with COVID-19 compared to a random sample of medical ICU patients with conditions other than COVID-19.Demographic and therapeutic factors affecting patients admitted to medical intensive care units in the Kansas City metro area are reported from May 5, 2020 until June 2, 2020 using a retrospective case-control study examining gender, race, and therapeutic options including modes of ventilation, vasopressor requirements, renal-replacement therapy, and disposition. RESULTS: During data collection, patients being treated for COVID-19 in intensive care units in the Kansas City metropolitan area were more likely to be older, less likely to be white, and less likely to be immunosuppressed as compared to those being treated for non-COVID illnesses. They were more likely to require non-invasive ventilation and undergo prone positioning but were equally likely to require invasive ventilation and other organ supportive therapy. CONCLUSIONS: Hospitalized patients being treated for COVID-19 in the Kansas City metropolitan area have similar demographics to those being reported in the U.S. including age and race. Additionally, establishing a Critical Care Task Force in response to the pandemic allowed for preparation for a potential surge, establishing capacity, and disseminating timely information to policy makers and critical care workers on the front line.

ABSTRACT

Rationale: Coronavirus disease 2019 (COVID-19) can cause disruption of the renin-angiotensin system in the lungs, possibly contributing to pulmonary capillary leakage. Thus, angiotensin receptor blockers (ARBs) may improve respiratory failure. Objective: Assess safety of losartan for use in respiratory failure related to COVID-19 (NCT04335123). Methods: Single arm, open label trial of losartan in those hospitalized with respiratory failure related to COVID-19. Oral losartan (25 mg daily for 3 days, then 50 mg) was administered from enrollment until day 14 or hospital discharge. A post-hoc external control group with patients who met all inclusion criteria was matched 1:1 to the treatment group using propensity scores for comparison. Measures: Primary outcome was cumulative incidence of any adverse events. Secondary, explorative endpoints included measures of respiratory failure, length of stay and vital status. Results: Of the 34 participants enrolled in the trial, 30 completed the study with a mean age SD of 53.8 ± 17.7 years and 17 males (57%). On losartan, 24/30 (80%) experienced an adverse event as opposed to 29/30 (97%) of controls, with a lower average number of adverse events on losartan relative to control (2.2 vs. 3.3). Using Poisson regression and controlling for age, sex, race, date of enrollment, disease severity at enrollment, and history of high-risk comorbidities, the incidence rate ratio of adverse events on losartan relative to control was 0.69 (95% CI: 0.49-0.97) Conclusions: Losartan appeared safe for COVID-19-related acute respiratory compromise. To assess true efficacy, randomized trials are needed.
