Predicting Post-Concussion Symptoms (RPQ Score) for Two Different Patients Based on the Clinical Model

Patient 1: Woman, mild systemic disease (mild obesity), history of headaches, psychiatric history (depression), secondary education, part-time employed, TBI caused by motor vehicle accident, not intoxicated, Total ISS 9, one nonreactive pupil.

Total RPQ score = 7.295 (intercept) +(1.098*1)+(3.323*1)+(4.460*1)+(1.524*1)+(0.192*1)+(-0.709*log(9))+ (0.584*log(9)^2) +(3.910*1) = 24

Patient 2: Man, no systemic disease, no psychiatric history, bachelor degree, full-time employed, TBI caused by fall, not intoxicated, Total ISS 2, reactive pupils.

Total RPQ score = 7.295+(-3.376*1)+(-0.709*log(2))+(0.584*(log(2 )^2) = 4

TBI, traumatic brain injury; ISS, injury severity score.
