FUNC Score Calculator

The FUNC score is a clinical assessment tool that predicts, at hospital admission, which primary ICH patients are likely to attain functional independence at 90 days following ICH.[1]

FUNC Score Prediction Tool

The FUNC score is intended to provide guidance in clinical decision-making and patient selection for clinical trials. The components of FUNC score[2] (age, GCS, ICH location, ICH volume, and pre-ICH cognitive impairment) are obtained on evaluation of patients with ICH upon arrival to the hospital. Based on the number of points assigned within each category (see FUNC Score Prediction Tool inset or dropdown menu) of the individual components, a total FUNC score is calculated (range 0-11). For each individual ICH patient, a particular FUNC score value corresponds to the % probability of attaining functional independence (Glasgow Outcome Score greater than or equal to 4) at 90 days (Entire Cohort).

To eliminate the effects of early withdrawal of care on outcome, we also calculated the likelihood of long-term functional recovery in those ICH patients who survived to 90 days (Survivors Only), and their % probabilities of achieving functional independence at 90 days are presented below, as well. In our study, no patient assigned a FUNC score less than or equal to 4 achieved functional independence at 90 days, while greater than 80% with a score of 11 did in both patient cohorts.
