Addressing and Inspiring Vaccine Confidence in Black, Indigenous, and People of Color During the Coronavirus Disease 2019 Pandemic.

During the coronavirus disease 2019 (COVID-19) pandemic, we have witnessed profound health inequities suffered by Black, Indigenous, and People of Color (BIPOC). These manifested as differential access to testing early in the pandemic, rates of severe disease and death 2-3 times higher than white Americans, and, now, significantly lower vaccine uptake compared with their share of the population affected by COVID-19. This article explores the impact of these COVID-19 inequities (and the underlying cause, structural racism) on vaccine acceptance in BIPOC populations, ways to establish trustworthiness of healthcare institutions, increase vaccine access for BIPOC communities, and inspire confidence in COVID-19 vaccines.

Aminoglycoside Dosing and Volume of Distribution in Critically Ill Surgery Patients.

Background: At a tertiary referral and Level I trauma center, current institutional guidelines suggest initial aminoglycoside doses of gentamicin or tobramycin 4 mg/kg and amikacin 16 mg/kg for patients admitted to surgical intensive care units (SICUs) with suspected gram-negative infection. The objective of this study was to evaluate initial aminoglycoside dosing and peak serum drug concentrations in critically ill surgery patients to characterize the aminoglycoside volume of distribution (Vd) and determine an optimal standardized dosing strategy. Methods: This retrospective, observational, single-center study included adult SICU patients who received an aminoglycoside for additional gram-negative coverage. Descriptive statistics were used to evaluate the patient population, aminoglycoside dosing, and Vd. Multivariable linear regression was applied to determine variables associated with greater aminoglycoside Vd. The mortality rate was compared in patients who achieved adequate initial peak concentrations versus those who did not. Results: One hundred seventeen patients received an aminoglycoside in the SICUs, of whom 58 had an appropriately timed peak concentration measurement. The mean Acute Physiology, Age, and Chronic Health Evaluation (APACHE) II score was 27.8 ± 8.9. The Vd in patients receiving gentamicin, tobramycin, and amikacin was 0.49 ± 0.10, 0.41 ± 0.09, and 0.53 ± 0.13 L/kg, respectively. Together, the mean aminoglycoside Vd was 0.50 ± 0.12 L/kg. Gentamicin or tobramycin 5 mg/kg achieved goal peak concentrations in 24 patients (63.2%), and amikacin 20 mg/kg achieved the desired concentrations in nine patients (50.0%). Net fluid status, Body Mass Index, and vasopressor use were not predictive of Vd. There was no difference in the in-hospital mortality rate in patients who achieved adequate peak concentrations versus those who did not (26.8% versus 26.7%; p = 0.99). Conclusion: High aminoglycoside doses are needed in critically ill surgery patients to achieve adequate initial peak concentrations because of the high Vd. Goal peak concentrations were optimized at doses of gentamicin or tobramycin 5 mg/kg, and amikacin 20 mg/kg.
