The OESIL score for syncope helps assess the risk of 12-month all-cause mortality in individuals who experience syncope. This risk stratification tool evaluates four key factors related to the patient’s clinical profile.

The computation involves checking whether each of the following conditions applies:

- Age is greater than 65 years
- History of cardiovascular disease
- Syncope occurred without any warning (prodrome)
- ECG shows abnormalities

Each condition that is present contributes a score of 1 to the total OESIL score. Therefore, the total score ranges from 0 to 4, with each point increasing the level of risk. This straightforward scoring system translates the presence of clinical risk factors into a numerical value. Here’s how the score is interpreted:

- A score of **0** means the risk of 12-month all-cause mortality is **0%**.
- A score of **1** indicates a **0.8%** risk.
- A score of **2** suggests a **19.6%** risk.
- A score of **3** corresponds to a **34.7%** risk.
- A score of **4** represents a **57.1%** risk.

By translating clinical observations into these structured scores, clinicians can better understand and communicate the potential severity of a syncope incident, thereby guiding informed decision-making for further management.

The OESIL (Osservatorio Epidemiologico sulla Sincope nel Lazio) score for syncope is a clinical calculator used to predict the one-year risk of mortality in patients who present with syncope, a sudden, brief loss of consciousness followed by spontaneous recovery. This scoring system is particularly useful in the emergency department setting to stratify patients based on their risk and guide further management. The OESIL score takes into account factors such as age, cardiovascular history, abnormal ECG findings, and the nature of the syncope episode. It does not have specific exclusion criteria, but it should be noted that it is less accurate in predicting short-term outcomes and is not designed to identify the underlying cause of syncope.
