Select patients, such as those in long-term health facilities or nursing homes, may have an AVPU score of less than A, which is considered the patient's baseline. It plays a role in Rapid Response Activation Criterion and Early Warning Scores to detect changes in a patient's physiologic status in hopes of becoming aware of and correcting any potentially life-threatening issues that could have arisen during a patient's hospital stay. Health care professionals within a hospital utilize this scale during patient assessment for any patients at risk of having an abnormal level of consciousness. Utility in Hospital Care and Long Term Healthcare FacilitiesĪMS is one of the strongest predictors of death on the wards. EMS crews may begin with AVPU, followed by a GCS assessment if the AVPU score is below "A." AVPU is less detailed than the Glasgow Coma Scale, but it is performable more quickly. AVPU was initially used in the primary survey of trauma patients, as a decreased mental status could indicate inadequate circulation of oxygenated blood to the brain. It can be utilized during first aid and in the pre-hospital setting as any score lower than an "A" is considered abnormal until proven otherwise. This result should prompt the examiner to conduct additional assessments or begin more definitive care. The AVPU scale is a quick and simple way of detecting altered mental status (AMS) in a patient. No formal training is necessary to use this score. Utility in First Aid, Pre-Hospital Care, and Emergency Care One study has shown it to have the best interrater reliability for assessing the altered loss of consciousness (LOC) of traumatic and non-traumatic causes among AVPU, GCS, and ACDU. It is useful in evaluating patients in the pre-hospital and acute care setting for possible traumatic brain injury. The Simplified Motor Score (SMS) categorizes and scores patients in the following three categories: obeys commands, localizes pain, and withdraws to pain or worse. This even distribution may indicate that ACDU is superior at identifying early deterioration in the conscious level when they occur in critically ill ward patients than AVPU. The median values of ACDU were more evenly distributed than AVPU when researchers compared both scales to GCS. Additionally, median GCS scores associated with ACDU were 15, 13, 10, and 6. One study showed that ACDU might be superior for the simple ward assessment of seriously ill patients compared to AVPU. The ACDU Scale (alertness, confusion, drowsiness, and unresponsiveness) is another 4-point scale similar to AVPU. Further, the routine tracking of GCS and/or RASS on the wards may improve the accuracy of detecting patients with deteriorating clinical status. The Glasgow Coma Scale (GCS) and the Richmond Sedation and Agitation Scale (RASS) are two scales used for assessing mental status. One study showed that both GCS and RASS in admitted patients were significantly more accurate predictors of mortality than AVPU. Other scales for assessing mental status exist and may be superior to AVPU in specific settings. It is important to note, for example, that a total score of 8 could be E2V2M4 or E1V1M6, with very different implications for the severity of the patient's condition.Comparison With Other Scales of Mental Status This provides an overview summary of the severity of the patient's condition, but this score does not communicate the more informative detailed description of each response, which should always be used in addition to the score in clinical care of an individual patient. The short hand numbers can also be added together to give a total Coma Score (e.g.

However, when describing the patient always use the full criteria alongside the numbers to ensure that the assessment is accurately understood.
In addition to plotting trends on a coma scale chart, a patient's ratings can be documented numerically as a short hand aid to quickly record findings (e.g. This assessment may include performing cranial imaging (usually computed tomography (CT)) to identify problems such as haematomas, contusions or brain swelling. The observations can then be clearly communicated and the trends rapidly appreciated so that any improvement or deterioration in a patient's condition can be seen.ĭeterioration in a patient's condition should precipitate urgent medical review in order to identify any remediable factors that have contributed to this change.
