Factors associated with COVID-19 vaccine receipt at two integrated healthcare systems in New York City: A Cross sectional study of healthcare workers

ObjectivesTo examine factors associated with COVID-19 vaccine receipt among healthcare workers, including healthcare worker job type, race, and gender, as well as the role of vaccine confidence in decisions to vaccinate, and to better understand specific concerns related to COVID-19 vaccination among healthcare workers. DesignCross-sectional anonymous survey among front-line, support service, and administrative healthcare workers. SettingTwo large integrated healthcare systems (one private and one public) in New York City during the initial rollout of the COVID-19 vaccine among healthcare workers. Participants1,933 healthcare workers, including nurses, physicians, allied health professionals, environmental services staff, researchers, and administrative staff. Main Outcome MeasuresThe primary outcome was COVID-19 vaccine receipt during the initial rollout of the vaccine among healthcare workers. ResultsAmong 1,933 healthcare workers who had been offered the vaccine, 81% had received the vaccine at the time of the survey. Receipt was lower among Black (58%) compared with White (91%) healthcare workers; and lower among Hispanic (69%) compared with non-Hispanic (84%) healthcare workers. Among healthcare workers with concerns about COVID-19 vaccine safety, 65% received the vaccine. Among healthcare workers who agreed with the statement that the vaccine is important to protect family members, 86% were vaccinated. Of those who disagreed, 25% received the vaccine. Across all participants, 27% expressed concern about being experimented on with the COVID-19 vaccine. In a multivariable analysis, concern about being experimented on with the COVID-19 vaccine, concerns about COVID-19 vaccine safety, lack of influenza vaccine receipt, disagreeing that COVID-19 vaccination is important to protect family members, and Black race were independently associated with COVID-19 vaccine non-receipt. Over 70% of all healthcare workers responded that they had been approached for vaccine advice multiple times by family, community members, and patients. ConclusionsOur data demonstrated high overall receipt among healthcare workers. Even among healthcare workers with concerns about COVID-19 vaccine safety, side effects, or being experimented on, over 50% received the vaccine. Attitudes around the importance of COVID-19 vaccination to protect others played a large role in healthcare workers decisions to vaccinate. We observed striking inequities in COVID-19 vaccine receipt, particularly affecting Black and Hispanic workers. Further research is urgently needed in developing strategies with healthcare workers to address issues related to vaccine equity and uptake in the context of systemic racism and barriers to care. This is particularly important given the influence healthcare workers have in vaccine decision-making conversations in their communities. SUMMARY BOXES What is already known?O_LIHigh uptake of effective COVID-19 vaccines among healthcare workers is critical to pandemic response. C_LIO_LIIn studies of potential COVID-19 vaccine acceptance prior to COVID-19 vaccine availability, people who identified as Black were less likely to indicate they would accept the vaccine. C_LIO_LIUnderstanding reasons why some healthcare workers chose not to get the COVID-19 vaccine will help us develop interventions to improve COVID-19 vaccine confidence among healthcare workers and in their communities. C_LI What this study addsO_LIWe demonstrate high receipt of COVID-19 vaccines in the initial rollout among healthcare workers. C_LIO_LIAttitudes around the importance of COVID-19 vaccination to protect others played a large role in healthcare workers decisions to vaccinate. C_LIO_LIWe observed substantially lower rates of receipt among Black and Hispanic healthcare workers, independent of differences in vaccine-related beliefs. A quarter of healthcare workers expressed concerns about being experimented on. These results suggest systemic racism may be a critical barrier to equitable vaccination. C_LIO_LIOur results highlight that healthcare workers of all types, including those with non-patient-facing roles, play an important role as sources of COVID-19 vaccine information in their communities.

Acute Kidney Injury in Hospitalized Patients with COVID-19

ImportancePreliminary reports indicate that acute kidney injury (AKI) is common in coronavirus disease (COVID)-19 patients and is associated with worse outcomes. AKI in hospitalized COVID-19 patients in the United States is not well-described. ObjectiveTo provide information about frequency, outcomes and recovery associated with AKI and dialysis in hospitalized COVID-19 patients. DesignObservational, retrospective study. SettingAdmitted to hospital between February 27 and April 15, 2020. ParticipantsPatients aged [≥]18 years with laboratory confirmed COVID-19 ExposuresAKI (peak serum creatinine increase of 0.3 mg/dL or 50% above baseline). Main Outcomes and MeasuresFrequency of AKI and dialysis requirement, AKI recovery, and adjusted odds ratios (aOR) with mortality. We also trained and tested a machine learning model for predicting dialysis requirement with independent validation. ResultsA total of 3,235 hospitalized patients were diagnosed with COVID-19. AKI occurred in 1406 (46%) patients overall and 280 (20%) with AKI required renal replacement therapy. The incidence of AKI (admission plus new cases) in patients admitted to the intensive care unit was 68% (553 of 815). In the entire cohort, the proportion with stages 1, 2, and 3 AKI were 35%, 20%, 45%, respectively. In those needing intensive care, the respective proportions were 20%, 17%, 63%, and 34% received acute renal replacement therapy. Independent predictors of severe AKI were chronic kidney disease, systolic blood pressure, and potassium at baseline. In-hospital mortality in patients with AKI was 41% overall and 52% in intensive care. The aOR for mortality associated with AKI was 9.6 (95% CI 7.4-12.3) overall and 20.9 (95% CI 11.7-37.3) in patients receiving intensive care. 56% of patients with AKI who were discharged alive recovered kidney function back to baseline. The area under the curve (AUC) for the machine learned predictive model using baseline features for dialysis requirement was 0.79 in a validation test. Conclusions and RelevanceAKI is common in patients hospitalized with COVID-19, associated with worse mortality, and the majority of patients that survive do not recover kidney function. A machine-learned model using admission features had good performance for dialysis prediction and could be used for resource allocation. Key PointsO_ST_ABSQuestionC_ST_ABSWhat is incidence and outcomes of acute kidney injury (AKI) in patients hospitalized with COVID-19? FindingsIn this observational study of 3,235 hospitalized patients with COVID-19 in New York City, AKI occurred in 46% of patients and 20% of those patients required dialysis. AKI was associated with increased mortality. 44% of patients discharged alive had residual acute kidney disease. A machine learned predictive model using baseline features for dialysis requirement had an AUC Of 0.79. MeaningAKI was common in patients with COVID-19, associated with increased mortality, and nearly half of patients had acute kidney disease on discharge.
