Medicina di laboratorio in
urgenza/emergenza
I perché dell’integrazione
routine-urgenze
Davide Giavarina (Vicenza)
Laboratorio ‘Urgenze’: perché?
Fornire una via preferenziale a campioni
‘urgenti’, per ottenere una risposta più rapida
• ASAP: As Soon As Possible
• STAT: dal latino statim, immediatamente, subito
• TAT: Turn Around Time

Problemi del «Laboratorio Urgenze»
• Doppia gestione amministrativa
– Test routine e test STAT
• Aumento del numero delle richieste
• Strumentazione e aree analitiche diverse
– Allineamento
– Qualità
• Personale dedicato
– Conflitti nell’equipe
• Aumento delle risorse necessarie / costi

IL CONTESTO
D. Giavarina
Urgenze: integrazione o separazione?
• Quanti esami urgenti sul totale?
D. Giavarina
D. Giavarina
Cosa non è urgente?
Pazienti «interni»
• Acuti
• Monitoraggio
• Rapidità di decisione e
trattamento
– Clinica
– Organizzazione
– DGR
Pazienti «esterni»
• Post acuti
• Patologie croniche, gestite
in gran parte sul territorio
• Terapie di supporto per
pazienti complicati non
ospedalizzati
• Decisioni sempre più legate
agli esami di laboratorio
• Attese dei pazienti

Emergency Laboratory Tests
• EMERGENT (sec to min)
• POCT
– glucose, Hb/Ht, blood gases
• URGENT (<1hour)
– glucose, Hb/Ht, blood gases
• STAT LAB ?
– CBC, cardiac markers, PT,
electrolytes, CSF, ammonia,
osmolality, pregnancy test,
toxicology, therapeutic drugs
• NON-URGENT (>1hour)
– chemistry panels, urinalysis,
hCG, group A streptococcal
screen, KOH preparation,
Gram stain, cell count on
body fluids

Door to Needle:
the «golden hour» for evaluating and treating acute stroke
D. Giavarina
10 key best practice strategies
associated with faster DTN
• Advance hospital notification by Emergency Medical
Services (EMS)
• Rapid triage protocol and stroke team notification
• Single call to active stroke team
• Stroke tools
• Rapid acquisition and interpretation of brain imaging
• Rapid laboratory testing and point of care (POC) test
• Mix rt-PA medication ahead of time
• Rapid access to intravenous rt-PA
• Team-based approach
• Rapid data feedback

SITS-WATCH Follow-Up Report
SITS – WATCH study was initiated in
2011. The aim of the study is to
reduce the delay between arriving at
hospital and initiation of
thrombolysis (door-to-needle time,
DNT) to median below 40 minutes,
i.e., for at least half of all patients.
D. Giavarina
Reccomendation
• Laboratory and radiology staff members are
alarmed during the transport and waiting for the
patient in the CT room.
• Lab personnel draw blood while you are
examining the patient
• Implement point-of-care INR, do not wait with
the decision until regular INR is ready in case POC
INR<1.7.
• Do not wait for other laboratory results,
especially if you have knowledge on recent
laboratory findings.

AUTOMAZIONE
D. Giavarina
Definition
• The concept of “STAT” (from Latin statim, meaning immediately) tests in
clinical setting is a time-honored tradition
• When specimen analysis was slow and tedious, it was logical to give a
special attention to those specimens that were urgent
• Today’s technology has made it possibile to treat stats as
routine specimens, provided the process time is made so
short that all results are being returned quickly
