Time-Critical Essentially, a serious condition in which there is rapid deterioration with time unless it is stopped.
Emergency Systems Emergency systems are designed and developed to manage Emergent and Time-Critical situations or events
NNT (Lansberg, Stanford University) • 0-90 minutes NNTB = 3.6 • 91-180 minutes NNTB = 4.3 • 181-270 minutes NNTB = 5.9 • 271 – 360 minutes NNTB = 19.3
NNT (Lansberg, Stanford University) • 0-90 minutes NNTB/H = 3.6/65 • 91-180 minutes NNTB/H = 4.3/38 • 181-270 minutes NNTB/H = 5.9/30 • 271 – 360 minutes NNTB/H = 19.3/14 Therefore gives the cut-off of 4.5 hours
4.5 hours • But we do not have this much time • We must act as soon as we can • In London we have a target of 30 minutes ‘Door-to-Needle’ • Which means that if a patient has a thrombolysable stroke, they must be receiving thrombolysis within 30 minutes of arriving at the ED
The Chain of Survival • Recognition of symptoms • Contact EMS (999) • Priority dispatch • EMS transport patient to the right hospital • EMS pre-alert • Early recognition of symptoms/signs • Early imaging • Early treatment
Easy-Peasy? • The more links in the chain, the more potential places that it can break • Chinese Whispers...
Easy-Peasy? • Airway compromise • Aspiration • Hypertension • Arrhythmia • Altered conscious level • Coagulopathy – on Warfarin?
Easy-Peasy? • Neurological Stroke Mimic • Variable Symptoms / Signs • Head Injury • Metabolic Injury • Psychiatric Illness
Stroke Team • What is a team? • Who should be in a stroke team? • What is the role of a team leader? • What is the role of a team member?
Stroke Doctor • Confirm FAST positive & time of onset • Look for inclusions / exclusions • More in-depth history & examination
ED doctor • ABC assessment • Interpret ECG • Contact CT and organise scan
ED Technician / FY2 • IV access • Routine bloods • Rapid INR test if on warfarin
ED / Stroke Nurse • ABC assessment • Attach directly to transport monitor • Perform ECG • Accompany patient to CT
Stroke Unit Sister • Aware of potential admission • Able to organise bed • Able to come and assist
Radiographer • Empty the scanner • Prepare for investigations
Receptionist • Book in patient immediately onto system
Porter • Check oxygen cylinder • Transport patient
What’s next? • Multiple patients • Haemorrhagic stroke • Airway problem • Not a stroke
Possible members • Anaesthetist • Physician • Stroke Nurse • Radiologist • Neurosurgeon
Summary • Time-critical illness needs a structured, safe approach • Does not mean we run around quickly • Develop a Team approach – many people with few, achievable tasks within their comfort zone • Regular meetings – build bonds, review practise, learn
