Description

Calculates the OESIL (Osservatorio Epidemiologico sulla Sincope nel Lazio) Score to predict 1-year all-cause mortality in patients presenting to the emergency department with syncope. The score stratifies patients based on four simple clinical variables.

Usage

oesil_syncope_score(age, cv_history, no_prodrome, abnormal_ecg)

Arguments

age	Numeric. Patient age in years. (> 65 years adds 1 point).
cv_history	Numeric (0 or 1). History of cardiovascular disease. (1 = Yes, +1 point).
no_prodrome	Numeric (0 or 1). Syncope occurring without prodromal symptoms. (1 = Yes, +1 point).
abnormal_ecg	Numeric (0 or 1). Abnormal electrocardiogram. (1 = Yes, +1 point).

Value

A list containing:

OESIL_Score	The calculated score (Range 0-4).
Est_1_Year_Mortality	Estimated 1-year mortality risk percentage based on the derivation cohort.

Examples

# Example 1: High Risk
# 70yo (+1), CV History (+1), Abnormal ECG (+1), Prodrome present (0)
# Score = 3
oesil_syncope_score(70, 1, 0, 1)

# Example 2: Low Risk
# 40yo, No history, No prodrome (+1), Normal ECG
# Score = 1
oesil_syncope_score(40, 0, 1, 0)
