Aims and Learning Outcomes
• To have an understanding of what is an Early Warning Tool and
why it should be used.
• To be able to use the Brighton Paediatric Early Warning Score.
• To be aware of future developments of the score.
History
• First used in adults in the early 90s.
• Obvious signs of deterioration prior to cardiac arrest.
(Franklynn and Mathew 1994)
• Early detection associated with improved outcomes in
adults. (McQuillan 1998)
• Work needed in education of staff in recognition of
the seriously ill patient. (Rouse 2001)
• 1st PEWS Brighton based on adult systems (2002)
• Published Feb 2005 (Monaghan 2005)
What is a Paediatric Early Warning
Score ?
• A tool to identify patients with serious physiological
disturbances at risk of deterioration.
• It is an objective assessment tool.
• It is a tool that may give us a numeric trend in the
patients condition.

How to use BPEWS
• Observe the child objectively.
• Consult the chart and score what you observe.
• If their score is usually high keep scoring them so to detect any
changes.
• Record the total in the observation chart.
• Carry out the actions as dictated.
Actions
• Actions range between informing the nurse in charge to calling
out the cardiac arrest team.
• Main aim to encourage discussion and management with child’s
own team
• Response times between 15 minutes and 1 hour.
• Critical Care Liaison informed if score of 4 or any concerns or
queries.
Challenges
•
•
•
•
•
•
•
•
•
•
New Concept.
Seen by staff as extra work.
Staff suspicious of motives.
What variables should be used?
Sensitivity
Verification
Fear of deskilling.
Change Management.
Lack of available evidence.
Education of Staff.
Common Misconceptions
•
•
•
•
•
It will get my patient to PICU
quicker.
Its too much paperwork.
Its time consuming.
I would recognise any sick
patient I don’t need a score.
Its too sensitive.

Audit and Research
• Pilot study examined triggers initially only examined score 4.
• Should have examined all levels.
• Audit of observations.
QuickTime™ and a
TIFF (Uncompressed) decompressor
are needed to see this picture.
Audit
• Examined standard of observations and the relationship to
PEWS.
• 2 main findings.
• Relationship between PEWS and quality of observations.
• Respiratory rate.
• PEWS and Respiratory rate.

2 studies submitted to LREC
To demonstrate that the Brighton Paediatric Early Warning Score reflects the child’s
severity of illness.
To demonstrate the interuser reliability of the (BPEWS)
1st study passed 2nd study to be resubmitted once study 1 is
complete
Study took 3 and a half years as difficulty recruiting group 3
subjects as scorer had to be the expert.

Interobserver Variability of the
Brighton PEWS Score
• Currently in progress
• Two nurses or Drs score independently
• Scores sealed in envelope and sent for analysis.
Tucker et al 2008
• Examined 2979 Children using Brighton PEWS
• Evaluated its ability to detect deterioration
• Relationship between BPEWS and transfer to PICU
• For each rise of 1 in BPEWS there was a two fold increase in
likelihood of transfer.
• Sensitivity was 90%.
• Specificity was 75% at score of 3.
• And specificity was 99% for children scoring 9.
• Limitation using PICU as an outcome.
Discussion

• 12 Year old Diabetic.
• Irritable,
• Heart Rate 100. Capillary refill 2-3 secs.

• Afebrile.
• Blood glucose 10mmols.
Scenario 2
• 4yr old.
• Not interested in surroundings or toys.
• Heart rate 140 bpm. Capillary refill 2-3 seconds.
