Premorbid frailty predicts short- and long-term outcomes of reperfusion treatment in acute stroke.

BACKGROUND: Frailty is the most important short- and long-term predictor of disability in the elderly and, thus, might influence the clinical outcome of acute treatment of stroke. OBJECTIVE: To evaluate whether frailty predicts short- and long-term all-cause mortality and neurological recovery in elderly patients who underwent reperfusion acute treatment of stroke. METHODS: The study included consecutive patients older than 65 years who underwent reperfusion treatment in a single stroke unit from 2015 to 2016. Predictors of stroke outcomes were assessed including demographics, baseline NIHSS, time to needle, treatment and medical complications. Premorbid frailty was assessed with a comprehensive geriatric assessment including functional, nutritional, cognitive, social and comorbidities status. At three and twelve months, all-cause death and clinical recovery (using modified Rankin scale, mRS) were evaluated. RESULTS: One-hundred and two patients who underwent acute reperfusion treatment for stroke entered the study (mean age 77.5, 65-94 years). Frailty was diagnosed in 32 out of 102 patients and associated with older age (p = 0.001) but no differences in baseline NIHSS score, vascular risk profile or treatment management strategy. Frailty status was associated with worse improvement at 24 h and higher in-hospital mortality. At follow-up, frail patients showed poorer survival at 3 (25% vs 3%, p = 0.008) and 12 (38% vs 7%, p = 0.001) months. Frailty was the best predictor of neurological recovery at one year follow-up (mRS 3.2 ± 1.9 vs 1.9 ± 1.9). DISCUSSION: Frailty is an important predictor of efficacy of acute treatment of stroke beyond classical predictors of stroke outcomes. Larger longitudinal studies are, thus, warranted to evaluate the risk-benefit of reperfusion treatment in the growing elderly frail population.

Reorganizing stroke and neurological intensive care during the COVID-19 pandemic in Germany.

The outbreak of coronavirus disease 19 (COVID-19) has dramatically imposed healthcare systems to reorganize their departments, including neurological wards. We aimed to describe the rearrangements made by stroke units (SU) and neurological intensive care units (ICU) in several German community and university hospitals facing the pandemic. This cross-sectional, survey-based, nationwide study collected data of 15 university and 4 community hospitals in Germany, being part of IGNITE Study Group, from April 1 to April 6, 2020. The rearrangements and implementation of safety measures in SUs, intermediate care units (IMC), and neurological ICUs were compared. 84.2% of hospitals implemented a separated area for patients awaiting their COVID-19 test results and 94.7% had a dedicated zone for their management. Outpatient treatment was reduced in 63.2% and even suspended in 36.8% of the hospitals. A global reduction of bed capacity was observed. Hospitals reported compromised stroke treatment (52.6%) and reduction of thrombolysis and thrombectomy rates (36.8%). All hospitals proposed special training for COVID-19 management, recurrent meetings and all undertook measures improving safety for healthcare workers. In an unprecedented global healthcare crisis, knowledge of the initial reorganization and response of German hospitals to COVID-19 may help finding effective strategies to face the ongoing pandemic.
