Impact of the COVID-19 Pandemic on Patients Without COVID-19 With Acute Myocardial Infarction and Heart Failure.

Background Excess mortality from cardiovascular disease during the COVID-19 pandemic has been reported. The mechanism is unclear but may include delay or deferral of care, or differential treatment during hospitalization because of strains on hospital capacity. Methods and Results We used emergency department and inpatient data from a 12-hospital health system to examine changes in volume, patient age and comorbidities, treatment (right- and left-heart catheterization), and outcomes for patients with acute myocardial infarction (AMI) and heart failure (HF) during the COVID-19 pandemic compared with pre-COVID-19 (2018 and 2019), controlling for seasonal variation. We analyzed 27 427 emergency department visits or hospitalizations. Patient volume decreased during COVID-19 for both HF and AMI, but age, race, sex, and medical comorbidities were similar before and during COVID-19 for both groups. Acuity increased for AMI as measured by the proportion of patients with ST-segment elevation. There were no differences in right-heart catheterization for patients with HF or in left heart catheterization for patients with AMI. In-hospital mortality increased for AMI during COVID-19 (odds ratio [OR], 1.46; 95% CI, 1.21-1.76), particularly among the ST-segment-elevation myocardial infarction subgroup (OR, 2.57; 95% CI, 2.24-2.96), but was unchanged for HF (OR, 1.02; 95% CI, 0.89-1.16). Conclusions Cardiovascular volume decreased during COVID-19. Despite similar patient age and comorbidities and in-hospital treatments during COVID-19, mortality increased for patients with AMI but not patients with HF. Given that AMI is a time-sensitive condition, delay or deferral of care rather than changes in hospital care delivery may have led to worse cardiovascular outcomes during COVID-19.

Estimating the effects of race and social vulnerability on hospital admission and mortality from COVID-19.

OBJECTIVE: To estimate the risk of hospital admission and mortality from COVID-19 to patients and measure the association of race and area-level social vulnerability with those outcomes. MATERIALS AND METHODS: Using patient records collected at a multisite hospital system from April 2020 to October 2020, the risk of hospital admission and the risk of mortality were estimated for patients who tested positive for COVID-19 and were admitted to the hospital for COVID-19, respectively, using generalized estimating equations while controlling for patient race, patient area-level social vulnerability, and time course of the pandemic. RESULTS: Black individuals were 3.57 as likely (95% CI, 3.18-4.00) to be hospitalized than White people, and patients living in the most disadvantaged areas were 2.61 times as likely (95% CI, 2.26-3.02) to be hospitalized than those living in the least disadvantaged areas. While Black patients had lower raw mortality than White patients, mortality was similar after controlling for comorbidities and social vulnerability. DISCUSSION: Our findings point to potent correlates of race and socioeconomic status, including resource distribution, employment, and shared living spaces, that may be associated with inequitable burden of disease across patients of different races. CONCLUSIONS: Public health and policy interventions should address these social factors when responding to the next pandemic.

Changes In Non-COVID-19 Emergency Department Visits By Acuity And Insurance Status During The COVID-19 Pandemic.

Prior studies suggest that the COVID-19 pandemic was associated with decreases in emergency department (ED) volumes, but it is not known whether these decreases varied by visit acuity or by demographic and socioeconomic risk factors. In this study of more than one million non-COVID-19 visits to thirteen EDs in a large St. Louis, Missouri, health system, we observed an overall 35 percent decline in ED visits. The decrease in medical and surgical visits ranged from 40 percent to 52 percent across acuity levels, with no statistically significant differences between higher- and lower-acuity visits after correction for multiple comparisons. Mental health visits saw a smaller decrease (-32 percent), and there was no decrease for visits due to substance use. Medicare patients had the smallest decrease in visits (-31 percent) of the insurance groups; privately insured (-46 percent) and Medicaid (-44 percent) patients saw larger drops. There were no observable differences in ED visit decreases by race. These findings can help inform interventions to ensure that people requiring timely ED care continue to seek it and to improve access to lower-risk alternative settings of care where appropriate.
