modified_soar_stroke_score: Modified SOAR Score for Stroke

Description

Calculates the Modified SOAR (mSOAR) Score to predict short-term (inpatient) mortality in patients with acute stroke. The score incorporates Stroke type, Oxfordshire Community Stroke Project (OCSP) classification, Age, pre-stroke modified Rankin Scale (mRS), and admission NIHSS score.

Usage

modified_soar_stroke_score(stroke_type, ocsp_classification, age, pre_stroke_mrs,
                           nihss_score)

Value

A list containing:

mSOAR_Score

The calculated score (Range 0-9).

Est_Inpatient_Mortality

Estimated probability of inpatient mortality based on derivation cohorts.

Arguments

stroke_type

String. Type of stroke: "infarct" (0 pts) or "hemorrhage" (1 pt).

ocsp_classification

String. Oxfordshire Community Stroke Project classification. "lacs": Lacunar syndrome (0 pts). "pacs": Partial anterior circulation syndrome (0 pts). "pocs": Posterior circulation syndrome (1 pt). "tacs": Total anterior circulation syndrome (2 pts).

age

Numeric. Patient age in years. <= 65: 0 pts. 66-85: 1 pt. > 85: 2 pts.

pre_stroke_mrs

Numeric. Pre-stroke Modified Rankin Scale score (0-5). 0-2: 0 pts. 3-4: 1 pt. 5: 2 pts.

nihss_score

Numeric. Admission NIH Stroke Scale score. 0-4: 0 pts. 5-10: 1 pt. >= 11: 2 pts.
