Background of neurocritical care
Describe an incremental implementation of NC at a public hospital University affiliated teaching hospital Level-1 Trauma center ~37 critical care beds (MICU and & SICU) 24/ 7 intensivist coverage ~ 1500 discharges per month

BackgroundCurrent Neurocritical Care Work Force
Evolution of Neuro critical fellowships Accredited by UCNS First Board exam in 2007 195 diplomates graduated so far
Neurocritical Care Society 127 members
~ 50 dedicated Neurointensive units in US
Trend towards regionalization of care

Critical care work force shortageIs evolution of Neurointensive Care Making It
Worse?
Huge gap between supply and demand
Growing shortage of general intensivists
Drawing CC physicians into a specialized areas
Fragmentation of critical care training: Surgical critical care Neurointensive care Cardiothoracic care
Reality: > 80% of critically ill patients are cared for in multidisciplinary units by
general intensivists

DEVELOPING A STROKE CENTER AT LINCOLN MEDICAL CENTER
Reluctance to institute thrombolytic therapy Shortage of vascular neurologists ED physicians reluctant to institute thrombolytic
therapy
~ 30 to 40% of admitted strokes will require ICU level of care
![Page 11: Delivering Neuro-Critical Care in a Public Hospital: A General Intensivist Experience](https://reader036.vdocument.in/reader036/viewer/2022062500/568153a1550346895dc1a55b/html5/thumbnails/11.jpg)
DEVELOPING A STROKE CENTER AT LINCOLN MEDICAL CENTER
Mandate to establish NYSDOH Primary Stroke Centers in 2005
Unique model of care Utilized intensive care physicians who were
present 24/ 7 at Lincoln Intensivist to lead stroke team
Protocols and policies developed Training with NIHSS Instituting thrombolytic therapy Obtaining stroke CMEs every year
![Page 12: Delivering Neuro-Critical Care in a Public Hospital: A General Intensivist Experience](https://reader036.vdocument.in/reader036/viewer/2022062500/568153a1550346895dc1a55b/html5/thumbnails/12.jpg)
Stroke Team ActivationFor patients presenting within 7 hours of symptom onset
ER ARRIVAL:Rapid triage, Stroke team activation
CT head , Labs
Not a candidate for lysis
Triage based on severity
Indication for Lysis or
clot removal
Start tPA and follow clinical pathway
Evaluation within 15 minutes by ICU MD(Stroke Team Leader)

Impact of the Stroke Initiative
Implemented an effective stroke system of care without need for additional resources
100% of all eligible patients received thrombolytic therapy compared to ~ 25 to 35% nationwide when
presenting within window

EXPANSION OF THE STROKE PROGRAM Endovascular therapy for ischemic strokes:
Expansion of time window for definitive therapy up to 8 hours
Mechanical clot removal
Large-vessel acute strokes: Derive less benefit from IV t-PA (compared
to lacunar or distal embolic strokes) Have less than a 30% recanalization NIHSS > 10 and MCA, PCA infarcts
associated with poor outcomes
