Bernstein-Parsonnet 2000 Risk Model: Explanation and Clinical Context The Bernstein-Parsonnet 2000 Model is a validated scoring system designed to estimate operative mortality risk in patients undergoing cardiac surgery.
It incorporates patient-specific variables including age, gender, left ventricular ejection fraction (LVEF), New York Heart Association (NYHA) functional class, history of previous cardiac surgery, and urgency of the procedure.
The model provides a numeric risk score that is converted into a predicted mortality percentage, assisting clinicians in preoperative risk stratification and informed consent discussions.
This tool helps in identifying high-risk patients, guiding perioperative management, and facilitating shared decision-making between physicians and patients.
