Rough Guide :Janet Treasure

ROUGH GUIDE TO A SUMMARY MEASURE OF RISK

Analogue of Risk Management:

1. No Coloured Scores

Regular review and monitoring of above parameters with routine referral to eating disorders

unit/ secondary services depending on local resources.

2. Score(s) in the Yellow/Concern Area

Regular review of parameters (c. weekly) and assessment of capacity with urgent referral to

eating disorders and appropriate medical intervention if needed.

3. Score(s) in the Red/Alert Area

Immediate contact and referral to eating disorders unit and physicians if outpatient with

assessment of capacity. The patient will need urgent specialist and medical assessment. If

inpatient - immediate contact with on-call physicians.

This table gives values of concern for each part of the assessment and is followed by a

management protocol based on risk.

Why a Modified Early Warning System for EDU’s

• Trusts’ expectation for use of NEWS

• Concerns that this not “fit for purpose” for ED patients

– False positives and false negatives

• Development of adaptations of NEWS for specific clinical groups e.g. PEWS

NEWSRoyal College of Physicians 2013

“MARSI” MEWS using information from physical observations effectively on inpatient EDUs

• MEWS - Modified Early Warning Score

• NEWS - National Early Warning Score

• “MARSI” MEWS – Development of a Meaningful Early Warning Score for Inpatient Eating Disorder Units

MARSI MEWS

Development

• Setting of MARSI MEWS parameters informed by

– Reference to existing community physical risk assessment tools

– Review of patients observation charts at Hayes

– Consultation with MARSIPAN physician

– Consultation via EDSIG list serve

Parameters

Development

• Design of MARSI MEWS Chart

– Piloted at Hayes Grove

• Exclusion of blood sugar from MARSI MEWS score calculation

• BM measurement of less than 5 triggers instructions on reverse of chart

Modification of MARSI MEWS following pilot at Hayes

Development

• Design of MARSI MEWS Chart

– Trialled on 6 Priory and one NHS sight following structured teaching

Development and training issues

• Importance of respiratory rate assessment, recording and scoring to be highlighted to staff

– Respiratory rate is an vital indicator of many bodily functions i.e. respiratory problems, cardiovascular problems, metabolic problems, neurological problems

• Clarification of recording and scoring of BP measurements

– one score for sitting systolic BP

– Second score for difference between sitting and standing BP

MARSI MEWS GROWS UP –do we eat it or play with it ?

The MARSI MEWS Study Phase 2

• Phase 1 has resulted in a large database of physical observations and corresponding MARSI MEWS and NEWS scores.

• The NEWS and the MARSI MEWS are different: NEWS scores tended to be higher than the corresponding MARSI MEWS score- is the NEWS too sensitive?

• Phase 2: To determine if the MARSI MEWS (an adapted version of the NEWS) is a better predictor of physical deterioration in inpatients with anorexia nervosa than the NEWS.

Patient Profiles

• We have compiled information on 60 patients from 2 units to create Patient Profiles.

• Profiles include STATE variables, showing the physical health of a patient on a given day (including the observations on the MARSI MEWS chart)

• And TRAIT variables with information regarding physical and psychiatric medical history.

YOUR MISSION (should you choose to accept it)!

• We would like you to examine the Patient Profiles handed out to you and indicate on the scoring sheet which clinical action you feel is most appropriate if you were confronted with this patient in an inpatient setting.

• There is also a space for any comments at the bottom of each scoring sheet.

• We will then compare this to the MARSI MEWS and NEWS scores that each profile would have scored.

• We will assess which tool (MARSI MEWS or NEWS) produces scores that best match the opinions of the clinicians (you!) as to which of the Patient Profiles are considered to be at risk of physical deterioration.
