Insights
Early COVID-19 pandemic saw fewer emergency department visits, particularly for pediatric and elderly patients, but increased admissions and length of stay. This impacts future pandemic preparedness.
Area of Science:
- Emergency Medicine
- Public Health
- Infectious Diseases
Background:
- The COVID-19 pandemic caused by SARS-CoV-2 has profoundly impacted healthcare systems globally.
- Academic emergency departments experienced unprecedented challenges during the initial phase of the pandemic.
Purpose of the Study:
- To analyze the early impact of the COVID-19 pandemic on patient visits and departmental operations in a major academic emergency department.
- To identify changes in patient demographics, chief complaints, and disposition during the initial months of the pandemic.
Main Methods:
- Retrospective analysis of emergency department data from January to July 2020.
- Comparison of patient visit data, demographics, chief complaints, and length of stay with the preceding two years.
Main Results:
- A 47% decrease in total patient visits was observed from March to July 2020, with significant reductions in pediatric (-73%) and elderly (-43%) populations.
- Notable decreases in visits for cardiovascular (-39%), neurological (-63%), headaches (-60%), back pain (-64%), abdominal pain (-51%), and minor trauma (-71%) were recorded.
- Conversely, there was a 54% increase in pulmonary complaints, alongside a 32% rise in admissions and a 40% increase in length of stay.
Conclusions:
- The early COVID-19 pandemic led to a significant decline in overall emergency department visits, especially among vulnerable groups and for non-respiratory conditions.
- Despite fewer visits, the department experienced increased admissions and longer patient stays, highlighting a shift in patient acuity and resource utilization.
- These findings underscore the need for adaptive strategies and robust planning for future public health crises impacting emergency care services.
Objective:
Coronavirus disease 2019 (COVID-19, caused by severe acute respiratory syndrome coronavirus 2 [SARS-CoV-2]) is a historic pandemic severely impacting health care. This study examines its early effect on a busy academic emergency department.
Methods:
A retrospective analysis of patients from an academic tertiary care Level I trauma, cardiac and stroke center's emergency department seeing an average of 54,000 adults and 21,000 pediatric patients per year. Total visits, reasons for patient visits, demographics, disposition, and length of stay were analyzed from January through July 2020 and compared with the same time period in the previous 2 y.
Results:
From March through July 2020 there were statistically significant decreases in the total number of patient visits (-47%) especially among pediatric (-73%) and elderly (-43%) patients and those with cardiovascular (-39%), neurological (-63%) complaints, headaches (-60%), back pain (-64%), abdominal pain (-51%), and minor trauma (-71%). There was, however, a significant increase in pulmonary complaints (+54%), as well as admissions (+32%), and length of stay (+40%).
Conclusions:
There was a significant drop in overall patients and select groups early in the pandemic, while admissions and emergency department length of stay both increased. This has implications for future pandemic planning.
