Early Warning Scoring

Automated early warning scoring
Rapid response to clinical deterioration with early warning scoring

Do your caregivers have the information they need to identify subtle signs of patient deterioration early? The indications of a patient’s clinical instability typically occur six to eight hours before an event.

 

An automated early warning scoring (EWS or MEWS) solution can help you identify the subtle signs of deterioration that can indicate a potential serious adverse event (SAE) and automatically re-check those warning signs, using Philips reassurance measurements, to determine if a notification needs to be sent to the appropriate caregivers. By reducing the need for manual record keeping and associated manual scoring calculations, automated EWS can help you identify patients at risk, reduce response times and put time back on your side.

 

Early detection of patient deterioration (and appropriate notification of caregivers) gives you more time to respond and plan appropiate intervention. EWS can support this. Automated EWS can support making this easy. Ask us about automated early warning solutions for your hospital.

Early warning scoring takes many forms

 

Acceptance of early warning scoring (EWS) has spawned a wide variety of different algorithms including MEWS, NEWS, PEWS, and more. What do they all mean?

 

EWS is based on the physiologic assessment of multiple vital signs –  respiratory rate, heart rate, systolic blood pressure, level-of-consciousness, body temperature, etc. Resulting observations are compared to a ‘normal range’ to generate a single composite score. This is done either manually, or automatically (i.e. Philips bedside monitors). An increasing score produces an escalated response – from increased observation, to rapid response. It is how this process is ‘modified’ to address the requirements of a specific patient/application type that results in the unique nomenclature.

 

You may also encounter Single Parameter Scoring (SPS), which scores each individual patient vital sign alone, but does not score them ‘together’ as MEWS does. With SPS, caregivers may need to consider a response when a single vital sign is out of range.

MEWS – Modified Early Warning Scoring is just that – an EWS system whose parameters have been customized to suit the requirements of a particular institution and the patients they serve. A further segmentation of MEWS adapts EWS to specific purposes. Following is a partial list:

Automated EWS makes a significant difference

A study using Philips IntelliVue GuardianSoftware supports the use of an automated EWS system with notifications to provide significant improvements in key patient centered clinical outcomes.1

20 percent reduction
reduction in hospital mortality, including readmissions1
35 percent reduction
reduction of Severe Adverse Events1
66 percent reduction
reduction in ICU mortality of patients transferred to the ICU1
86 percent reduction
reduction of Cardiopulmonary Arrests1

Success in implementation

Why EWS? Consider the facts

63%

of preventable deaths are attributable to failure to rescue by a registered nurse or physician.2

Problem: It’s hard to predict which patients to watch closely

Solution: IntelliVue Guardian EWS helps you identify subtle signs that can indicate a potential deterioration

70%

of cardiac patients show evidence of respiratory decline within eight hours of cardiac arrest3

Problem: An MD is notified only 25% of the time4
Solution: IntelliVue Guardian incorporates respiratory measurements into EWS to initiate timely intervention

150k

in-hospital cardiac arrests annually in the U.S.5

Problem: Most deteriorating patients are identified within 15 minutes – often too late to intervene
Solution: EWS tools can support improving the effectiveness of your Rapid Response Teams (RRT)

patient care

Accurate assessment and consistent reporting of respiratory rate is extremely important to detect patient deterioration early. However, manually measuring respiratory rates can be time consuming and overwhelming6.
