Coronavirus had created fear among all of us around the world. The pause in the day to day life and the economic fall across the globe are the main reason behind it. Looking into this situation ISARIC built a tool Coronavirus Clinical Characterisation Consortium which will set up the patients with coronavirus and divide them into four groups and treat them accordingly.
The groups were made by various tests and clinical data carried out on a patient on arrival in England, Wales, and Scotland. The chances of death from being low to high was determined using the collected data.
This tool has a great value because it easily helps the doctors to determine the high risk of death among the patients who need to get treatment immediately and start with the process.
As the existing tools had a shortage, a group of UK researchers set out to develop and validate a pragmatic risk stratification score. To develop it they collected data from around 35,463 adults (median age 74 years) suffering from coronavirus and were admitted in the hospitals across England, Scotland, and Wales between 6 February and 20 May 2020.
Data collected during the process was –
- The number of underlying conditions (comorbidities)
- The respiratory rate at the time of admission
- Blood oxygen concentration
- Level of consciousness
- C-reactive protein (a chemical linked to inflammation)
All these were then examined and then put under a score ranging from 0 to 21 points.
Patients with a score of 15 or more had 62% morality compared to the ones having scores of 3 or less having one percent. This suggests that the patients with the low-risk groups would be carry forwarded for managing in the community. But the ones within the intermediate risk groups would require ward level monitoring as declared by the researchers.
The patients with a score of 9 or above were at high risk ( nearly 40%) who required deep treatment including the initiation of steroids and early escalation to critical care.
The model was assured after the researchers tested it again over 22,361 patients admitted to the same hospitals between 21 May and 29 June 2020. The score was similar even after various other factors were taken into the account and then the good news was confirmed.
In the end, the researcher however said that it is a very easy tool to use and gives valid predictions in-hospital mortality and helps to categorize patients as being at low, intermediate, high, or very high risk of death.
The researchers also added that the score performed better than the other tools, showed accurate treatment required for the patients, and had the same performance as of the other complicated device.
