The "pain rate" for a patient with sickle cell disease refers to the number of pain episodes per year. This is a measure of disease severity and is one of the factors associated with premature death in a patient who is over 20 years old. Platt et al developed an equation using a Poisson model to predict the pain rate for a patient with sickle cell disease.
