Notes

• In this calculator, mcg is the abbreviation for micrograms.
• This calculator represents findings from the literature referenced below. It is important to understand that these findings may not be representative of the experience in your local healthcare system.
• FAPIC: Fibrinogen, Age, Platelets, Intracerebral hemorrhage, Central venous thrombosis.

Calculation Details and Variables

• FibrinogenFactor is assigned values by this ordered logic:
  • If Fibrinogen <150 mg/dL, FibrinogenFactor = 1
  • Else FibrinogenFactor = 0.
• AgeFactor is assigned values by this ordered logic:
  • If Age ≤60 yr, AgeFactor = 1
  • Else AgeFactor = 0.
• PlateletsFactor is assigned values by this ordered logic:
  • If Platelets <25 x10^3/mcL, PlateletsFactor = 1
  • Else PlateletsFactor = 0.
• Equation parameters such as Intracranial Hemorrhage (ICH), have two or more discrete values that may be used in the calculation. The numbers in the parentheses, e.g. (0), represent the values that will be used.
