RCHSD PEWS on CHEX – incomplete

Code Blue Resuscitation events continue to occur outside of the Critical Care Unit.


  • To describe what PEWS is and how it is used.
  • To describe why PEWS can be a useful tool.
  • To accurately score a patient using PEWS
  • To indicate action steps for PEWS of 3 or higher.

PEWS is an assessment objective tool using 3 criteria that has been found to be reliable for early prediction of deteriorating patient status.

  • PEWS is utilized in non-critcal care areas.
  • A PEWS score is calculated with each patient assessment
  • A PEWS algorithm guides decision making and actions.

Rationale for PEWS Literature Review

One Study (Buist 1999) showed 76%  of arrests were preceded a period marked by clinical instability. The average period of instability prior to arrest was 6.5 hours. in a second study (Franklin & Matthew 1994)  66% of patients who arrested had abnormal S&S within 6 hours of arrest, but the MD was notified in only 25%.  In several studies retrospective chart review showed increased PEWS were evident as much as 24 hours prior to to a code or RRT. (Tucker et al 2008, Parshuram et al 2009, CHCA 2009)

Benefits of PEWS

PEWS improves collaboration and communication among providers. Improves confidence of bedside staff. Improves recognition of early patient deterioration and need for interventions. Improves escalation process for patient concerns. Improves reduction of preventable codes.

Retrospective Review of LCHSD Data

A review of 2009 LCHSD events reveal that 25% of the events had a critical PEWS score 2 – 13 hours prior to the code call. 59% of 2009 RRT activations had a critical PEWS 1-17 hours prior to activation.

Prospective Results from HemOnc Pilot

Code Blue on the HemOnc Unit decreased to 0 and RRT events increased

PEWS is based on Normal Vital Sign Parameters

PEWS Algorithm – need to insert here

What if my patient is scoring ≥ 4 and MD has been notified?

After a provider assessment, a patient specific modification plan can be developed regarding notification of provider for increased PEWS Scores. For repeat scores of 4,5, or 3 in one category where the initial notification to the patient provider has occurred and an acceptable patient specific care plan has been established, repeat notification is not required.

What PEWS isn’t

PEWS does not replace subjective nursing and physician intuition or ‘gut feeling.”

A Rapid Response or Code Blue can be activated at any time the patient condition warrants and does not depend on the patient’s PEWS score.

You do not need permission to call a Code Blue.

Ways PEWS can be Used

  • PEWS can be used to balance patient care assignments.
  • PEWS can be used by providers to prioritize rounding.
  • PEWS can help guide patient placement, patient transfer, or discharge.
  • PEWS can help differentiate between stable and potentially unstable children.

Method of Implementation Here

  • PEWS are calculated each time vital signs are obtained
  • Unit PEWS data boards are updated q 4-6 hours
  • PEWS is utilized in charge RN meetings, shift report, rounds, resident sign off, transfers, and handoffs.

PEWS in Epic


PEWS is documented from the Vital Signs, General Doc Flowsheet


The MD/NP comm row will have drop-down list to chose actions from. : 2nd RN Assessment, Charge RN assessed, MD notified, Interventions ordered, RT intervention, Transfer to higher level of care, RRT, Code Blue. Sidebar report has a hyperlink to the PEWS Algorithm. The scoring grid in not available, for unknown reasons, apparently none thinks anyone will need to consult it.

PEWS Data Goes in Patient List Add these three columns to your patient list. (Insert image here)

  • PEWS Score
  • A PEWS of 3 in a single category
  • Last PEWS Date and Time

PEWS Graph is available from the patient list

PEWS Report has been added to the Patient Summary Index

Patient is 17 m/o w/Hx of Sz. Video EEG in progress. Code called at 16:50, d/t Seizure.

  1. Calculate PEWS from the assessment prior to Code call. At 12:00 HR: 140, RR: 40, FiO2 =RA, mild retractions, pink, cap refill < 2, irritable, but consolable. 0, 1, 0, 1, 0, 0,  answer here
  2. What is appropriate action to take based on the algorithm?
    1. Consult with another RN to confirm the score.
    2. Reassess and rescuer with every VS assessment
    3. Consult with Charge RN and confirm score; notify HO/primary team.
    4. Reassess every 2 hours

  3. Patient  8 y/o RRT activated @ 00:50. Calculate the PEWS score for the following assessment prior to the RRT call. VS @23:00 HR 155, RR 40, FiO2 40%, 4L NC, mild retractions, pink, cap refill < 2 sec,; irritable and not consolable. answer here
  4. What is appropriate action to take based on the algorithm?
    1. Consult with another RN to confirm the score.
    2. Reassess and rescuer with every VS assessment
    3. Consult with Charge RN and confirm score; notify HO/primary team.
    4. Notify the Charge RN immediately; Notify the Resident or Primary with mandatory urgent visit and call RRT.
