In healthcare, risk stratification involves assessing patients based on their health status, medical history, and other factors to identify those at a higher risk of certain health outcomes or complications.
This process helps healthcare providers allocate resources more efficiently, target interventions, and personalize care plans based on individual patient needs.

[[Risk]] [[stratification]] uses a mix of objective and subjective data to assign risk levels to patients. Practices can systematically use patient risk levels to make care management decisions, such as providing greater access and resources to patients at higher risk levels.

Is the determination of the quantitative or qualitative value of risk related to a concrete situation and a recognized threat (also called hazard). Quantitative risk assessment requires calculations of two components of risk (R):, the magnitude of the potential loss (L), and the probability (p) that the loss will occur. Acceptable risk is a risk that is understood and tolerated usually because the cost or difficulty of implementing an effective countermeasure for the associated vulnerability exceeds the expectation of loss.

Since preoperative risk assessment on the basis of standard anatomical imaging alone is often insufficient, noninvasive identification and visualization of [[eloquent area]]s in the preoperative work-up is becoming increasingly important in [[brain tumor]] [[surgery]]
