background
Background

Despite recommendations in the most recent triennial reports, ‘Saving Mothers’ Lives’ (CMACE) and documented improvements in patient care using early warning scoring systems (EWS) in the general adult population, no validated system currently exists for the obstetric population.

obstetric early warning score chart1
Obstetric Early Warning Score Chart
  • It is recognised that pregnancy and labour are normal physiological events. However, observation of vital signs are an integral part of care
  • There is a potential for any woman to be at risk of physiological deterioration and this cannot always be predicted. There is also evidence that there is poor recognition of deterioration in condition
  • Regular recording and documentation of vital signs will aid recognition of any change in a woman’s condition
  • The use of EWS chart prompts early referral to an appropriate practitioner, who can undertake a full review, order appropriate investigations, resuscitate and treat as required

Early Warning Scoring System and Action Protocol for Early Pregnancy, Antenatal and Postnatal

  • The colour trigger (yellow and red) is simple and visual. A numerical score is more complex
  • Red is the colour denoting serious patient condition requiring urgent action
  • Yellow is the colour suggesting that the patient condition is worsening requiring escalation of treatment
  • Balance between too much information on a chart causing distraction and maximising useful variables recorded
who needs an obstetric ews chart
Who needs an Obstetric EWS Chart?
  • All women whose clinical condition requires close observation; admitted early pregnancy, antenatal or postnatal
  • All post operative cases – in recovery and following transfer from theatre
  • Any woman giving cause for concern (medical or obstetric causes)
  • During/Following APH/PPH/Eclampsia
  • Suspected infection e.g. Prolonged SROM
  • High-risk women in delivery suite (not in labour)
how frequently should the chart be completed
How frequently should the chart be completed?

Frequency of Observations is determined by;

  • Risk Status
  • Diagnosis / Reason for admission
  • Initial observations on admission
  • Protocol
  • An individual plan of care should be made by the Midwife/Nurse and Doctor which should specify the frequency of physiological observations
  • The minimum frequency of observations as an in-patient is 12 hourly.

What sections need to be completed?

  • All sections to be completed and include either;

A/N, P/N, or EP loss, tick the relevant

colour coded section

What if a section is not applicable?

  • Insert NA within box provided

NA – Not applicable

Respiratory Rate

  • You must document the number. For example, you would write ‘22’ in the yellow column

Oxygen Saturation

  • You must document the number. For example, you would write ‘99’ in the white column

Oxygen

  • If you perform a set of observations you must document on the chart in the space provided if oxygen is delivered. This must always include the percentage oxygen
  • If the woman is on air you must document this instead of an oxygen percentage. Do not leave the oxygen section blank. Room Air = RA

Temperature

  • A ● should be inserted to aid viewing and connect dots with straight lines (not illegible comma shapes)

Heart rate

  • This should be documented as a ● Please take care to keep the chart legible and connect dots with straight lines. If concerned a numerical value may be inserted

Blood Pressure- Graphic trend using arrows & a dotted line

  • You document this with an upward arrow ( ˄ )at the systolic and a downward arrow ( ˅ ) at diastolic, joined by a dotted line so you have a graphic trend. Numerical value may be documented.

obstetric early warning scores
Obstetric Early Warning SCORES
  • Calculate and record the total number of yellow and/or red scores, including those on the line
  • You must always have a score

documented

  • If OEWS does trigger a score document in case notes and inform midwife/nurse in charge
  • Follow the action protocol documented on the back page of the chart and record action in the case notes
  • You are expected to report if you have any clinical concerns irrespective of the OEWS score.

Action Protocol

ACTION PROTOCOL

The Early Warning Scoring System and Action Protocol are designed to help identify deterioration in the woman and ensure appropriate early intervention. All action taken must be fully documented in case notes. Staff should use their clinical judgement, and seek advice if they have concerns about any woman, regardless of the score.

If an OEWS chart is being commenced in a freestanding midwife led unit the parent obstetric unit needs to be informed and transfer protocols commenced

Action Protocol
  • Continue observations as before

White Only

  • Inform Midwife/Nurse in Charge
  • Recheck observations in 1 hour (or more frequently if clinically indicated)

Single Yellow

  • Inform Midwife/Nurse in Charge
  • Immediately ontact the on-call obstetric SHO/Reg using SBAR to review the woman within 30 mins
  • Recheck observations in 30 minutes (or more frequently if clinically indicated)

≥ 2 Yellow or 1 Red

Action Protocol
  • Inform Midwife/Nurse in Charge
  • Immediately ontact the on-call obstetric SHO/Reg using SBAR to review the woman within 20 mins
