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. Recommendations for midwifery practice as set out in Chapter 13 of Saving Mothers’ Lives Carry out, record and act upon basic observations for Both women at low and higher risk of complication. “There remains an urgent need for the routine use of a national modified early obstetric warning score(MEOWS) chart in all pregnant or postpartum women who become unwell and require either obstetric or gynaecology services. This will help in the more timely recognition, treatment and referral of women who have, or are developing, a critical illness during or after pregnancy. ” Recommendation 6: Specialist clinical care: identifying and managing very sick women

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

Regional OEWS Chart 2013 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? 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? 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.

Completing the Obstetric EWS Chart 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

Completing the Obstetric EWS Chart 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 Calculate and record the total number of yellow and/or red scores, including those on the line 2 You must always have a score documented 1 GM 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
