Early warning scores
Mrs. Parvathy
Tutor, sjcon
DEFINITION
• Early Warning Scores have been
developed to facilitate early detection
of deterioration by categorizing a
patient’s severity of illness and
prompting nursing staff to request a
medical review at specific trigger
points utilizing a structured
communication tool (Mitchell et al.,
2010)
HOW EARLY WARNING
SCORE WORKS ???
PHYSIOLOGICAL PARAMETERS
• AGE
• URINE OUTPUT
• PAIN
• GENDER / ETHINICITY &
OBESITY
• CO MORBIDITIES AND
IMMUNOSUPRESSION
INCLUSION CRITERIA FOR
EARLY WARNING SCORES • Acute hospital setting
• All patients above 16 yrs of age –
initial assessment
• Outpatients / and day care patients
who comes for invasive procedures or
those who receive anesthesia.
EXCLUSION CRITERIA
CLINICAL RESPONSE TO
NEWS• THREE MAIN COMPONENTS
FREQUENCY OF MONITORING
COMPETENCY OF TEAM
URGENCY OF CLINICAL REVIEW
CLINICAL PROCESS
MEASUREMENT & DOCUMENTATION OF INFORMATION
ESCALATION OF CARE
EMERGENCY RESPONSE SYSTEMS
CLINICAL COMMUNICATION
NEWS SCORING SYSTEM
SCORING SYSTEM …CONTD
• Each parameter carries a point. If the
patient receive oxygen an additional 2
points will be added with final score
• A low score : an aggregate NEWS of
1–4
• A medium score: a NEWS aggregate
score of 5 or more, or a RED score, ie
an extreme variation
• A high score: an aggregate NEW score
of 7 or more
• A low NEWS score can be attended
by competent registered clinical nurse
• RN can determine the frequency of
monitoring / or need for escalation of
care.
• NEWS medium scores should be
attended by ward level doctor or by a
acute care nurse .
• NEWS high score should be taken
care by critical care outreach team –
and usually transfers patients to high
dependency area.
FREQUENCY OF CLINICAL
MONITORING
• Patients who scored zero should be
monitored every 12 hours
• Medium scored patients should be
evaluated every 4 hours
• High score patients should be evaluated
hourly .
RELEVANCE OF EWS IN
INDIA
• Acute /Tertiary care hospitals in India
are overloaded – helps to relieve
burden of care
• EWS helps on call teams to prioritize
their works – which case need most
urgency in attending
• A modified tool accurate to Indian
setting can be developed according to
hospital protocols .
HELPS TO PRIORTIZE CARE

REDUCE HUMAN ERROR
RESPONSE RIGHT AT THE POINT OF CARE
CASE STUDY – 1
• Mr. R is a 75 year old man , found
lying on the street by police. On
assessment his BP is 100/75 mm Hg ,
Pulse rate is 110 beats / mts,
respiration is 9 breaths/ mts
temperature is 102 F and SPO2 is
98%. Classify the patient??
• Respiration – 1
• Oxygen saturation – 0
• Supplemental oxygen – 0
• Temperature - 1
• Systolic BP -1
• Heart rate - 1
• Level of consciousness – 3
• TOTAL = 7 - RED
CASE STUDY – 2

TAKE HOME MESSAGES
EWS SYSTEM WILL WORK
ONLY IF
STAFFS ARE TRAINED IN NEWS
RESPONSE SYSTEMS AND STAFF ARE IN PLACE TO DELIVER CARE
MEASURE AND RECORD THE SYSTEM FOR EACH SIX PARAMETER
AGGREGRATE THE SCORE AND ADD 2 IF OXYGEN SUPPLEMENTED
