The Preoperative Mortality Predictor (PMP) score is a clinical calculator used to estimate the risk of mortality in patients undergoing non-cardiac surgery. It is particularly useful for clinicians when planning surgical interventions, as it helps to identify high-risk patients and guide preoperative decision-making. The PMP score takes into account several factors including age, functional status, and the presence of comorbidities such as heart failure, liver disease, and cancer. It does not apply to patients undergoing cardiac surgery, as the risk factors and outcomes for these patients are different. The PMP score should be used with caution in patients with conditions not included in the score, as it may underestimate their risk.

# Scoring:
- If score <= 5, then Risk of perioperative mortality is 0.1%
- If score <= 10, then Risk of perioperative mortality is 0.6%
- If score <= 15, then Risk of perioperative mortality is 2.4%
- If score <= 20, then Risk of perioperative mortality is 12.6%
- If score <= 25, then Risk of perioperative mortality is 37.5%
- If score >= 26, then Risk of perioperative mortality is 40.0%
- If score == 0, then Please make a selection)
