Comorbidity–polypharmacy score
In medicine, the Comorbidity–polypharmacy score is a measure of overall severity of comorbidities. It is defined as the simple sum of the number of known comorbidities and pre-admission medications taken by the patient, as a surrogate for the “intensity” of the comorbidities.
This score has been tested and validated extensively in the trauma population, demonstrating good correlation with mortality, morbidity, triage, and hospital readmissions. Increasing levels of CPS were associated with significantly lower 90-day survival in the original study of the score in trauma population.
