Six simple physiological parameters form the basis of the scoring system: i) respiratory rate ii) oxygen saturations iii) temperature iv) systolic blood pressure v) pulse rate vi) level of consciousness.
NEWS is a tool developed by the Royal College of Physicians which improves the detection and response to clinical deterioration in adult patients and is a key element of patient safety and improving patient outcomes.
These elements are:
- measurement and documentation of observations.
- escalation of care.
- rapid response systems.
- clinical communication.
- organisational supports.
- education.
- evaluation audit and feedback.
- technological systems and solutions.
Critical care: the eight vital signs of patient monitoring
- Temperature.
- Pulse.
- Blood pressure.
- Respiratory rate.
- Oxygen saturation (SpO2)
- Pain.
- Level of consciousness.
- Urine output.
The NEWS2 adjustment for patients with/at risk of T2RF differs from NEWS in the assignment of weights to measured SpO2(NEWS weights SpO2 values below 96%; NEWS2 below 88%). Additionally, for patients with/at risk of T2RF, NEWS2 assigns weights for SpO2 values above 92% when receiving oxygen.

Identifies pediatric patients at risk for clinical deterioration. Originally developed to provide a practical and objective method to identify pediatric inpatients at risk for cardiac arrest. Can be used by staff and providers at all levels to escalate care for sick patients.
The NEWS chart provides a system for: Recording NEWS physiological observations. Alerting staff when these physiological observations fall outside accepted ranges. Prompting escalation of care and clinical review.
The recommendation for a NEWS2 aggregate score of 0 (that is, no change to any parameter) is a minimum 12‑hourly review and to continue routine monitoring.
News is information about current events. This may be provided through many different media: word of mouth, printing, postal systems, broadcasting, electronic communication, or through the testimony of observers and witnesses to events. News is sometimes called "hard news" to differentiate it from soft media.
Determining a MEWS score involves assigning a number between 0 and 3 to each of the six vital signs (see Figure 2 below). For example, if a patient's systolic blood pressure is between 71 and 80, or if it is more than 200, the nurse would assign that vital sign a score of 2.
While a score of 5 or more has been shown to be associated with a higher likelihood of admission to an intensive care unit or death, this threshold can be modified to accommodate different patient populations or clinical settings.
Designed for use with med-surg patients regardless of diagnosis, the MEWS screening tool has a numeric scale based on physiologic assessment criteria for screening and scoring patients. Parameters include respiratory rate, heart rate, systolic blood pressure, LOC, and body temperature.
Mews' parameters (systolic blood pressure, heart rate, respiratory rate, temperature and level of consciousness) were evaluated every six hours. The following events were reported: death, cardiopulmonary arrest and transfer to intensive care.
Mews is a British name for a row or courtyard of stables and carriage houses with living quarters above them, built behind large city houses before motor vehicles replaced horses in the early twentieth century. It is now commonly used in English-speaking countries for city housing of a similar design.
MEOWS is a way of formalising measurement of physiological variables. The values of the observations are then translated into a summary score which has a critical threshold, above which medical review and intervention is required (see appendix 2 MEOWS call out cascade).
