A method and system for determining the fall risk of a patient is provided. The method includes the evaluation of a patient to determine whether the patient exhibits one or more intrinsic fall risk factors selected from a group consisting of confusion, depression, altered elimination, dizziness, male gender, antiepileptic / anticonvulsant prescriptions and benzodiazepine prescriptions. A specific point value is assigned to each of the intrinsic risk factors found to be exhibited by the patient. A mobility test is also performed on the patient to evaluate the patient's ability to rise from a seated position, and a specific mobility test point value is assigned to the patient based upon the patient's performance of the mobility test. Each intrinsic risk factor's specific point value is then summed together with the specific mobility test point value to achieve a total risk score, and the patient's fall risk is determined based on the total risk score. An intervention process may be developed for the patient based on the patient's fall risk.
