simplified_pesi_score: Simplified Pulmonary Embolism Severity Index (sPESI)

Description

Calculates the Simplified PESI score to predict 30-day mortality in patients with confirmed pulmonary embolism (PE). The score uses 6 variables to stratify patients into Low Risk (score of 0) or High Risk (score >= 1), aiding in the decision for outpatient versus inpatient management.

Usage

simplified_pesi_score(age, cancer_history, chronic_cardiopulmonary_disease,
                      heart_rate, systolic_bp, oxygen_saturation)

Value

A list containing:

sPESI_Score

The calculated total score (Range 0-6).

Risk_Category

Classification (Low Risk = 0, High Risk >= 1).

Est_30_Day_Mortality

Estimated 30-day mortality risk percentage.

Recommendation

Suggested management strategy.

Arguments

age

Numeric. Patient age in years. (> 80 years adds 1 point).

cancer_history

Numeric (0 or 1). History of cancer. (1 = Yes, +1 point).

chronic_cardiopulmonary_disease

Numeric (0 or 1). History of chronic cardiopulmonary disease. (1 = Yes, +1 point).

heart_rate

Numeric. Heart rate in beats per minute. (>= 110 bpm adds 1 point).

systolic_bp

Numeric. Systolic blood pressure in mmHg. (< 100 mmHg adds 1 point).

oxygen_saturation

Numeric. Arterial oxyhemoglobin saturation (%). (< 90% adds 1 point).
