ABSTRACT
BACKGROUND: The World Health Organisation declared a coronavirus disease 2019 (COVID-19) pandemic on March 11, 2020. Following activation of the UK pandemic response, our institution began planning for admission of COVID-19 patients to the neurointensive care unit (neuro-ICU) to support the local critical care network which risked being rapidly overwhelmed by the high number of cases. This report will detail our experience of repurposing a neuro-ICU for the management of severely ill patients with COVID-19 while retaining capacity for urgent neurosurgical and neurology admissions. METHODS: We conducted a retrospective process analysis of the repurposing of a quaternary level neuro-ICU during the early stages of the COVID-19 pandemic in the United Kingdom. We retrieved demographic data, diagnosis, and outcomes from the electronic health care records of all patients admitted to the ICU between March 1, 2020 and April 30, 2020. Processes for increase in surge capacity, reduction in ICU demand, and staff redeployment and rapid training are reported. RESULTS: Over a 10-day period, total ICU capacity was increased by 21.7% (from 23 to 28 beds) while the capacity to provide mechanical ventilation was increased by 77% (from 13 to 23 beds). There were 30 ICU admissions of 29 COVID-19 patients between March 1 and April 30, 2020; median (range) length of ICU stay was 9.9 (1.3 to 32) days, duration of mechanical ventilation 11 (1 to 27) days, and ICU mortality rate 41.4%. There was a 44% reduction in urgent neurosurgical and neurology admissions compared with the same period in 2019. CONCLUSIONS: It is possible to repurpose a dedicated neuro-ICU for the management of critically ill non-neurological patients during a pandemic response, while maintaining access for urgent neuroscience referrals.

OBJECTIVE: To investigate whether serum S100B is suitable as a sensitive biomarker for early prediction of increased intracranial pressure and mortality rates after brain injury. DESIGN: A prospective, longitudinal study. SETTING: Neurosurgical intensive care unit. PATIENTS: Twenty-one patients with acute brain injury and 13 healthy controls. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: We assessed Glasgow Coma Scale score and pupil reaction on admission and quantified serum S100B (in-house enzyme-linked immunosorbent assay) and intracranial pressure on admission and the subsequent 6 days. Serum S100B concentrations on admission and day 1 were significantly higher in patients with fatal outcome (p <.05, p<.01, respectively), with a sensitivity of 100% and a specificity of 75-83%. Patients with high serum S100B on admission had an eight-fold and on day 1 a 12-fold increased relative risk of a fatal outcome. Subsequent serum S100B values predicted the development of high intracranial pressure in patients with traumatic brain injury (p <.01). Patients with high intracranial pressure on day 5 had an 11-fold and on day 6 a nine-fold increased risk of fatal outcome. CONCLUSIONS: Serum S100B is a sensitive biomarker for early prediction of the development of high intracranial pressure and fatal outcome following acute brain injury. Monitoring S100B concentrations could contribute to early detection of patients at risk of secondary increases in intracranial pressure and subsequent mortality. This would allow earlier targeting of therapy in selected patients.
