Admission rates and care pathways in patients with atrial fibrillation during the COVID-19 pandemic-insights from the German-wide Helios hospital network.
Several reports indicate lower rates of emergency admissions in the cardiovascular sector and reduced admissions of patients with chronic diseases during the Coronavirus SARS-CoV-2 (COVID-19) pandemic. The aim of this study was therefore to evaluate numbers of admissions in incident and prevalent atrial fibrillation and flutter (AF) and to analyse care pathways in comparison to 2019.
A retrospective analysis of claims data of 74 German Helios hospitals was performed to identify consecutive patients hospitalized with a main discharge diagnosis of AF. A study period including the start of the German national protection phase (13 March 2020 to 16 July 2020) was compared to a previous year control cohort (15 March 2019 to 18 July 2019), with further sub-division into early and late phase. Incidence rate ratios (IRRs) were calculated. Numbers of admission per day (A/day) for incident and prevalent AF and care pathways including readmissions, numbers of transesophageal echocardiogram (TEE), electrical cardioversion (CV), and catheter ablation (CA) were analysed.
During the COVID-19 pandemic, there was a significant decrease in total AF admissions both in the early (44.4 vs. 77.5 A/day, IRR 0.57 [95% confidence interval (CI) 0.54-0.61], P < 0.01) and late (59.1 vs. 63.5 A/day, IRR 0.93 [95% CI 0.90-0.96], P < 0.01) phases, length of stay was significantly shorter (3.3 ± 3.1 nights vs. 3.5 ± 3.6 nights, P < 0.01), admissions were more frequently in high-volume centres (77.0% vs. 75.4%, P = 0.02), and frequency of readmissions was reduced (21.7% vs. 23.6%, P < 0.01) compared to the previous year. Incident AF admission rates were significantly lower both in the early (21.9 admission per day vs. 41.1 A/day, IRR 0.53 [95% CI 0.48-0.58]) and late (35.5 vs. 39.3 A/day, IRR 0.90 [95% CI 0.86-0.95]) phases, whereas prevalent admissions were only lower in the early phase (22.5 vs. 36.4 A/day IRR 0.62 [95% CI 0.56-0.68]), but not in the late phase (23.6 vs. 24.2 A/day IRR 0.97 [95% CI 0.92-1.03]). Analysis of care pathways showed reduced numbers of TEE during the early phase [34.7% vs. 41.4%, odds ratio (OR) 0.74 [95% CI 0.64-0.86], P < 0.01], but not during the late phase (39.9% vs. 40.2%, OR 0.96 [95% CI 0.88-1.03], P = 0.26). Numbers of CV were comparable during early (40.6% vs. 39.7%, OR 1.08 [95% CI 0.94-1.25], P = 0.27) and late (38.6% vs. 37.5%, OR 1.06 [95% CI 0.98-1.14], P = 0.17) phases, compared to the previous year, respectively. Numbers of CA were comparable during the early phase (21.6% vs. 21.1%, OR 0.98 [95% CI 0.82-1.17], P = 0.82) with a distinct increase during the late phase (22.9% vs. 21.5%, OR 1.05 [95% CI 0.96-1.16], P = 0.28).
During the COVID-19 pandemic, AF admission rates declined significantly, with a more pronounced reduction in incident than in prevalent AF. Overall AF care was maintained during early and late pandemic phases with only minor changes, namely less frequent use of TEE. Confirmation of these findings in other study populations and identification of underlying causes are required to ensure optimal therapy in patients with AF during the COVID-19 pandemic.

Impact of the COVID-19 pandemic on emergency department attendances and acute medical admissions.
To better understand the impact of the COVID-19 pandemic on hospital healthcare, we studied activity in the emergency department (ED) and acute medicine department of a major UK hospital.
Electronic patient records for all adult patients attending ED (n = 243,667) or acute medicine (n = 82,899) during the pandemic (2020-2021) and prior year (2019) were analysed and compared. We studied parameters including severity, primary diagnoses, co-morbidity, admission rate, length of stay, bed occupancy, and mortality, with a focus on non-COVID-19 diseases.
During the first wave of the pandemic, daily ED attendance fell by 37%, medical admissions by 30% and medical bed occupancy by 27%, but all returned to normal within a year. ED attendances and medical admissions fell across all age ranges; the greatest reductions were seen for younger adults in ED attendances, but in older adults for medical admissions. Compared to non-COVID-19 pandemic admissions, COVID-19 admissions were enriched for minority ethnic groups, for dementia, obesity and diabetes, but had lower rates of malignancy. Compared to the pre-pandemic period, non-COVID-19 pandemic admissions had more hypertension, cerebrovascular disease, liver disease, and obesity. There were fewer low severity ED attendances during the pandemic and fewer medical admissions across all severity categories. There were fewer ED attendances with common non-respiratory illnesses including cardiac diagnoses, but no change in cardiac arrests. COVID-19 was the commonest diagnosis amongst medical admissions during the first wave and there were fewer diagnoses of pneumonia, myocardial infarction, heart failure, cellulitis, chronic obstructive pulmonary disease, urinary tract infection and other sepsis, but not stroke. Levels had rebounded by a year later with a trend to higher levels of stroke than before the pandemic. During the pandemic first wave, 7-day mortality was increased for ED attendances, but not for non-COVID-19 medical admissions.
Reduced ED attendances in the first wave of the pandemic suggest opportunities for reducing low severity presentations to ED in the future, but also raise the possibility of harm from delayed or missed care. Reassuringly, recent rises in attendance and admissions indicate that any deterrent effect of the pandemic on attendance is diminishing.
