MEWS v.1.1
MEWS acts as a 'track and trigger' system (reaction system) that is used to provide an objective indication of the degree of disease in a patient, so that actions can be put in at the right time. The MEWS score must always lead to a decision to continue treatment plan. With MEWS-measurements and clear action plans, the possibility increases of both detecting and treating failing patients in time.
To calculate a score based on categorising physiological readings and observations, as a simple method to support objective assessment of the degree of illness in an unwell patient.
Use to record a composite score to support assessmennt of the degree of illness in an unwell patient. The Modified Early Warning Score (MEWS) is based on five parameters easily controlled for through simple bedside examination: - Respiration rate - Systolic blood pressure - Heart rate - Level of consciousness (AVPU) - Body temperature A total score of ≥5p and/or 3p of one parameter should result in higher level of care as it is consistent with deteriorating state of the patient and increased risk of cardiac arrest and need for intensive care. Several hospitals use locally modified versions of the instrument including urine output - the model can be adjusted to accommodate specific requests.
Not to be used to record National Early Warning Score (NEWS).
