The original scoring system was developed before the invention of pulse oximetry and used the patient's colouration as a surrogate marker of their oxygenation status. A modified Aldrete scoring system was described in 1995 [2] which replaces the assessment of skin colouration with the use of pulse oximetry to measure SpO 2.
1—3.2%; 2—13.0%; 3—17.0%; 4—41.5%; 5—57.0%; The CURB-65 has been compared to the pneumonia severity index in predicting mortality from pneumonia. [6] It was shown that the PSI has a higher discriminatory power for short-term mortality, and thus is more accurate for low risk patients than the CURB-65 or its predecessor, the CURB score. [3]
Rockall risk scoring system attempts to identify patients at risk of adverse outcome following acute upper gastrointestinal bleeding. Rockall et al. identified independent risk factors [ 1 ] in 1996 which were later shown to predict mortality accurately.
It is often used as part of other scoring systems. FOUR score - 17-point scale for the assessment of level of consciousness. Aims to have higher sensitivity and specificity then GCS, applicable in intubated patients. CMM - Cancer Mortality Model [1] specific score to predict outcome of critical cancer patients; MPM - Mortality Probability Model ...
In the UK, the Royal College of Physicians developed the National Early Warning Score (NEWS) in 2012 to replace local or regional scores. [16] [17] [18] The NEWS score is the largest national EWS effort to date and has been adopted by some international healthcare services. [1] A second version of the score was introduced in 2017.
In gastroenterology, esophageal pH monitoring is the current gold standard for diagnosis of gastroesophageal reflux disease (GERD). It provides direct physiologic measurement of acid in the esophagus and is the most objective method to document reflux disease, assess the severity of the disease and monitor the response of the disease to medical or surgical treatment.
A raw score is a score without any sort of adjustment or transformation, such as the simple number of questions answered correctly. A scaled score is the result of some transformation(s) applied to the raw score, such as in relative grading. The purpose of scaled scores is to report scores for all examinees on a consistent scale.
Richmond Agitation-Sedation Scale (RASS) is a medical scale used to measure the agitation or sedation level of a person. It was developed with efforts of different practitioners, represented by physicians, nurses and pharmacists. [1] [2] The RASS can be used in all hospitalized patients to describe their level of alertness or agitation. [3]
