casualties are likely to be a mixture of categories with 25% requiring immediate life saving intervention (P1), 25% requiring intervention that can be delayed (P2) and 50% being walking wounded or minor injuries (P3).

Trauma triage is the use of trauma assessment for prioritising of patients for treatment or transport according to their severity of injury. Primary triage is carried out at the scene of an accident and secondary triage at the casualty clearing station at the site of a major incident. Triage is repeated prior to transport away from the scene and ag...
Trauma scores are often audit and research tools used to study the outcomes of trauma and trauma care, rather than predicting the outcome for individual patients. Many different scoring systems have been developed; some are based on physiological scores (eg, Glasgow Coma Scale (GCS)) and other systems rely on anatomical description (eg, Abbreviated...
Abbreviated Injury Scale (AIS)8
1. Since its introduction as an anatomical scoring system in 1969, the AIS has been revised and updated many times. 2. The AIS scale is similar to the Organ Injury Scale (OIS) introduced by the Organ Injury Scaling Committee of the American Association for the Surgery of Trauma; however, AIS is designed to reflect the impact of a particular organ injury on patient outcome. 3. The Association for the Advancement of Automotive Medicine monitors the scale. Limitations 1. The AIS scale does not p...
Injury Severity Score (ISS) and New Injury Severity Score (NISS)8
1. The ISS was introduced in 1974 as a method for describing patients with multiple injuries and evaluating emergency care. It has since been classed as the 'gold standard' of severity scoring. 2. Each injury is initially assigned an AIS score and one of six body regions (head, face, chest, abdomen, extremities, external). 3. The highest three AIS scores (only one from each body region may be included) are squared and the ISS is the sum of these scores. Limitations 1. Inaccurate AIS scores ar...
Organ Injury Scale
1. This scale provides a classification of injury severity scores for individual organs. 2. The OIS is based on injury description scaled by values from 1 to 5, representing the least to the most severe injury. 3. The Organ Injury Scaling Committee of the American Association for the Surgery of Trauma (AAST) developed the OIS in 1987; the scoring system has been updated and modified since that time12.
Glasgow Coma Scale
1. The GCS and the GPCS are simple and common methods for quantifying the level of consciousness following traumatic brain injury. 2. The scale is the sum of three parameters: 2.1. Best Eye Response 2.2. Best Verbal Response 2.3. Best Motor Response 3. Scales are based on values ranging between 3 (worst) to 15 (best)1.
The Acute Physiology and Chronic Health Evaluation
1. APACHE was first introduced in 1981. APACHE IV is an updated version introduced in 2006. 2. This evaluation system is used widely for the assessment of illness severity in intensive care units (ICUs)13.
Trauma and Injury Severity Score (TRISS)8
This score determines the probability of patient survival (Ps) from the combination of both anatomical and physiological (Injury Severity Score (ISS) and Revised Trauma Score (RTS), respectively) scores. A logarithmic regression equation is used: 1. Ps = 1/(1+e-b), where b = bo + b1 (RTS) + b2 (ISS) + b3 (Age Score)14 RTS and ISS are calculated as above and Age Score is either 0 if the patient is <55 years old or 1 if aged 55 and over. The coefficients b0-b3 depend on the type of trauma (NB:...
Future directions
1. Trauma triage and scoring is an ongoing development in process and new systems are being optimised on a daily basis. 2. Lactate measures may become more important in future. It is a better predictor of blood transfusion need and mortality16.
Apr 11, 2023 · The major incident triage tool (MITT) shows the recommended priority triage routes depending on incident characteristics. Each has a ‘yes’, which guides you to the next question, or ‘no’ answer which determines priority (P1, P2 and P3) or dead. Clinical instruction is in bold.
Apr 11, 2023 · The Ten Second Triage tool shows the recommended priority triage routes depending on incident characteristics. Each has a ‘yes’, which guides you to the next question, or ‘no’ answer which determines priority (P1, P2 and P3) or Dead. Clinical instruction is in bold.
P1 or P2 categories and treatments are prioritized over casualties with more urgent needs. Typically, trauma centres will allow a triage rate (number of P1 and P2 casualties) of up to 50% under ‘normal circumstances’ to allow the capture of all patients with severe injury, that is, prevent undertriage.5 However, in a mass

For example, where a nurse, midwife or nursing associate made a genuine clinical mistake during a course of treatment that ended with a patient’s death or serious injury, we can refer to the outcome, but only if it’s relevant as background context.
