About this deal

The motor scale has proved the most useful for assessment in both older children and preverbal children when studying blunt trauma. [5] Research has indicated that using the motor scale alone can simplify the assessment process while maintaining the accuracy of the score. [6] Method of Use [ edit | edit source ]

Mixed number. This is a way of expressing an improper fraction by simplifying it to whole units and a smaller overall fraction. It's an integer (whole number) and a proper fraction. The Glasgow Coma Scale was originally developed to help determine the severity of a coma or dysfunction following a traumatic brain injury, but can be useful for any condition leading to impaired consciousness. [3] Now that we have our whole number for the mixed fraction, we need to find our new numerator for the fraction part of the mixed number. Step 2: Get the new numerator Moderate TBI: GCS 9-12. These patients are typically drowsy or obtunded, they can open eyes and localise painful stimuli upon assessment.Marion D, Carlier P. Problems with initial Glasgow Coma Scale assessment caused by prehospital treatment of patients with head injuries. The Journal of Trauma: Injury, Infection, and Critical Care 1994;36(1):89-95. PMID: 8295256 (accessed 6 May 2017). Meredith W, Rutledge R, Fakhry S, Emery S, Kromhout-Schiro S. The conundrum of the Glasgow Coma Scale in intubated patients. The Journal of Trauma: Injury, Infection, and Critical Care 1998;44(5):839-845. PMID: 9603086 (accessed 7 May 2017). To work this out we'll use the whole number we calculated in step one (6) and multiply it by the original denominator (12). The result of that multiplication is then subtracted from the original numerator:

Teasdale G, Jennett B. Assessment of coma and impaired consciousness: a practical scale. The Lancet. 1974 Jul 13;304(7872):81-4. We first want to find the whole number, and to do this we divide the numerator by the denominator. Since we are only interested in whole numbers, we ignore any numbers to the right of the decimal point. It is argued that the GCS does not accurately score patients who are intubated and does not assess brainstem reflexes, which may account for its low predictive capacity. A GCS administered at 24 hours post-injury has an odds ratio of 0.4 for predicting in-hospital mortality. When administered at 72 hours post-injury, the odds ratio improves to 0.59 for predicting in-hospital mortality. [18]Before we begin, let's revisit some basic fraction terms so you understand exactly what we're dealing with here: Google Assistant is available on Philips Android TVs running on Android O (8) or higher OS version. Google Assistant is available in selected languages and countries. Evidence suggests that the Glasgow Coma Scale has a 71% accuracy in predicting functional independence post-injury. The GCS also modestly correlates with the Disability Rating Scale (-0.28) and the Cognitive component of the Functional Independence Measure (0.37).

The inter-rater reliability of the total Glasgow Coma Scale is p = 0.86. Some research has subdivided the inter-rater reliability for each subscale. For the eye score the inter-rater reliability is p = 0.76, the verbal score is p = 0.67, and the motor score is p=0.81. [11] The research for test-retest reliability is not recent and should be updated, however, the best available evidence is k = 0.66 - 0.77. [12] Given the current best available evidence, the GCS has a low sensitivity (56.1%) and a high specificity (82.2%). Therefore, there are very few false positives predicting a low rate of survival in healthy individuals. [17] Lesko M, Jenks T, Perel P, O'Brien S, Childs C, Bouamra O et al.

The sort code, which is a six-digit number, is usually formatted as three pairs of numbers, for example 12-34-56. It identifies both the bank and the branch where the account is held. In some cases, the first digit of the sort code identifies the bank itself and in other cases the first 2 digits identify the bank.[1] Although there is a strong correlation between BIC Codes and sort codes, sort codes are not explicitly encoded into BIC codes (although they are encoded into IBANs). It can also be administered in a variety of settings such as pre-hospital, arrival at the emergency department and in the hours following admission, giving it the ability to monitor changes and trends in patient consciousness over time.

Severe TBI: GCS 3-8. These patients present as obtunded to comatose, they are unable to follow directions. They may exhibit decorate or decerebrate posturing. [10] Nell V, Yates DW, Kruger J. An extended Glasgow Coma Scale (GCS-E) with enhanced sensitivity to mild brain injury. Archives of physical medicine and rehabilitation. 2000 May 1;81(5):614-7. Based on a recent systematic review, the total score is typically less reliable than the individual components with a total Kappa value of 77% as compared to the eye, motor, and verbal scores which had Kappa values of 89%, 94%, and 88% respectively.
