The PLAN score is a weighted sum of preadmission comorbidities, level of consciousness, age, and focal neurologic deficit findings at admission.

Domain	Item	Points	Maximum per domain
Preadmission comorbidities	Preadmission dependence in activities of daily living	1.5	5
Preadmission comorbidities	Cancer	1.5
Preadmission comorbidities	Congestive heart failure	1.0
Preadmission comorbidities	Atrial fibrillation	1.0
Level of consciousness	Reduced level of consciousness at presentation	5.0	5
Age	Age in decades (years ÷ 10, rounded down)	1 point per decade	10
Neurologic deficit	Significant or total arm weakness	2.0	5
Neurologic deficit	Significant or total leg weakness	2.0
Neurologic deficit	Neglect or aphasia	1.0
Total PLAN score		0 to 25 points

In this implementation, age points are calculated as floor(age in years ÷ 10). The total PLAN score is the sum of age points and all applicable item points.
