The Modified SOAR score for stroke aids in evaluating the risk of inpatient mortality for stroke patients by considering several key factors. It encompasses the type of stroke, classification according to the Oxfordshire Community Stroke Project, patient age, pre-stroke modified Rankin Score, and NIHSS Score. Based on these inputs, each option in a category is mapped to a distinct numerical value contributing to the final score.

Here's how input categories and their options contribute to the score:

- **Stroke Type**
  - Infarct: 0 points
  - Hemorrhage: 1 point

- **Oxfordshire Community Stroke Project Classification**
  - Total anterior circulation stroke: 2 points
  - Partial anterior circulation stroke: 0 points
  - Lacunar stroke: 0 points
  - Posterior circulation stroke: 1 point

- **Age**
  - <= 65: 0 points
  - 66-85: 1 point
  - >= 86: 2 points

- **Pre-stroke Modified Rankin Score**
  - 5: 2 points
  - 0-2: 0 points
  - 3-4: 1 point

- **NIHSS Score**
  - 0-4: 0 points
  - 5-10: 1 point
  - >= 11: 2 points

The sum of these scores yields a total between 0 and 9, reflecting the patient's risk of inpatient mortality. The interpretation of this score is as follows:

- A score of 0-1 indicates a mortality risk of 1.0%
- A score of 2 suggests a risk of 1.5%
- A score of 3 results in a risk of 6.5%
- A score of 4 signifies a risk of 9.2%
- A score of 5 corresponds to a risk of 19.5%
- A score of 6 presents a risk of 26.2%
- A score of 7 indicates a risk of 49.2%
- Scores of 8-9 convey a risk greater than 49.2%

This systematic approach evaluates a patient's condition on admission and informs clinical decisions with estimated risk percentages to guide care strategies effectively.

The Modified SOAR (Stroke subtype, Oxfordshire Community Stroke Project classification, Age, and prestroke modified Rankin) Score is a clinical calculator used in the management of stroke patients. It is specifically designed to predict the risk of death and dependency at discharge in patients with acute stroke. 

The Modified SOAR Score applies to patients who have been diagnosed with an acute stroke. It is particularly useful in the early stages of stroke management, helping clinicians to stratify patients based on their risk and guide treatment decisions. 

The score takes into account the type of stroke (ischemic or hemorrhagic), the Oxfordshire Community Stroke Project classification (which categorizes stroke based on clinical symptoms and signs), the patient's age, and their prestroke modified Rankin Score (a measure of disability). 

There are no specific exclusion criteria for the use of the Modified SOAR Score, but it may be less accurate in patients with transient ischemic attack (TIA) or in those with rare causes of stroke. It should also be used with caution in patients with significant comorbidities that could independently affect their prognosis.
