RESUMEN
PURPOSE: We aimed to evaluate utilization of inpatient hospital and critical care services among critically ill neurologic patients during the COVID-19 pandemic. We hypothesized, based on prior observations among ischemic stroke patients, that there would be significant decline in critically ill neurologic patients presenting to hospitals during the pandemic which may impact outcomes. METHODS: We used TriNetX, a large research network, collecting real-time electronic medical records data. We extracted data on utilization of critical care and hospital inpatient services among cohorts of patients with common neurocritical conditions between January-June 2020 and compared it to data from similar time-frames in previous years. We also compared clinical outcomes, comprising need for intubation and 30-day mortality, among these cohorts. RESULTS: We found a 28.1% reduction in intensive care unit (ICU) admissions with critical neurologic illnesses in 2020 when compared to 2019 (8568 vs. 11,917 patients, p â< â0.0001) and a 34.4% reduction compared to 2018 (8568 vs. 13,064 patients, p â< â0.0001). However, there was no statistically significant difference in mortality (2020: 12.2 vs. 2019: 12.4%; p â= â0.7; vs. 2018: 12.6%; p â= â0.62) or intubation rates across the years among patients using critical care services. There was 1% increase in mortality among non-ICU patients with similar diagnoses in 2020 compared to previous years (2020: 3.9% vs. 2019: 2.9% vs. 2018: 3.1%; p â< â0.0001, p â= â0.0001), but no difference in intubation rates. CONCLUSION: There was a significant reduction in hospital and ICU admissions among patients with acute neurologic emergencies in 2020, after onset of COVID-19 pandemic, compared to previous years. While we did not find a significant difference in mortality among patients admitted to the ICU, there was slightly higher mortality among non-ICU patients with same diagnoses in 2020 compared to previous years. Prospective evaluation and further investigation into the reasons for these trends is needed.
RESUMEN
BACKGROUND: Acute encephalopathy with COVID-19 has been reported in several studies but its impact on outcomes remains unclear. We hypothesized that hospitalized COVID-19 patients with encephalopathy have worse COVID-19 related outcomes. METHODS: We used TriNetX, with a large COVID-19 database, collecting real-time electronic medical records data. We included hospitalized COVID-19 patients since January 20, 2020 who had encephalopathy based on ICD-10 coding. We examined clinical outcomes comprising need for critical care services, intubation and mortality among these patients and compared it with patients without encephalopathy before and after propensity-score matching. RESULTS: Of 12,601 hospitalized COVID-19 patients, 1092 (8.7%) developed acute encephalopathy. Patients in the acute encephalopathy group were older (67 vs. 61 years) and had higher prevalence of medical co-morbidities including obesity, hypertension, diabetes, heart disease, COPD, chronic kidney and liver disease among others. Before and after propensity score-matching for co-morbidities, patients with acute encephalopathy were more likely to need critical care services (35.6% vs. 16.9%, p â< â0.0001), intubation (19.5% vs. 6.0%, p â< â0.0001) and had higher 30-day mortality (24.3% vs. 17.9%, p 0.0002). CONCLUSION: Among hospitalized COVID-19 patients, acute encephalopathy is common and more likely to occur in patients with medical co-morbidities and are more likely to need critical care, intubation and have higher 30-day mortality even after adjusting for age and underlying medical co-morbidities.
