Perme ICU Mobility Scoring System for Evaluating the Mobility Status of Patients in the ICU

The Perme ICU Mobility Score (Perme Score) is a fifteen-point assessment scale specifically tailored to measure important parameters for assessing the functional mobility of patients during an intensive care unit (ICU) stay.  The Perme Score, which ranges from 0 to 32, is derived from 15 items grouped into seven categories: mental status, potential mobility barriers, functional strength, bed mobility, transfers, gait, and endurance. The score is practical and can be quickly completed after mobility interventions.  The Perme Score has demonstrated inter-rater reliability for the Cardiovascular ICU (CVICU) patient population and, in another study, showed excellent inter-rater agreement and reliability (Perme C, Nawa RK, et al. (2014). Methodist Debakey Cardiovascular Journal). The Perme Score uses a maximum range of 2 to 4 points for each of the 15 items, and it provides a total score that reflects the patient’s mobility status at one particular moment in time, allowing for patients’ previous scores to be compared to new scores in order to monitor individual progress. High scores indicate minimal potential mobility barriers and decreased assistance, whereas low scores indicate more potential barriers to mobility and more assistance needed for mobility tasks.


Stage of Development


Clinical data: To date, the Perme ICU Mobility Scale has been licensed to more than 25 institutions in its written form and translated into 3+ different languages.


Competitive Landscape


Several functional mobility tools for patients in ICU have been used in published studies, including the Functional Status Score for Intensive Care Unit (FSS-ICU), Physical Function ICU Test (PFIT), The Chelsea Critical Care Physical Assessment tool (CPAx), ICU Mobility Scale (IMS), and Surgical ICU Optimal Mobility Score (SOMS). However, the Perme Score may provide a more comprehensive assessment of mobility status because of its ability to be applied to all patients in ICU and inclusion of environmental factors.


Competitive Advantages


•       Unique ability to address both mobility and ICU environmental factors which impact the progressive mobility of patients in ICU

•       Standardizes mobility status of patients in ICU for clinical and research purposes

•       Objective and quantitative

•       High reliability
