29% (68.57%-100%). Table 1 Patient Characteristics. Table 2 Inter-rater agreement. Kappa values for specific items were as follows: no agreement (k = 0) for item 2, fair agreement (k = 0.21 to 0.40) for item 1, and moderate agreement (k = 0.41 to 0.60) for items 5, 10, 12, and 13. There was substantial agreement (k = 0.61 to 0.80) for items 4, 7, 9, and 11, and high agreement (k = 0.81 to 1.00) for items Inhibitors,research,lifescience,medical 3, 6, 8, 14, and 15. Discussion The Perme ICU Mobility Score was conceived as an ICU-specific tool to measure mobility status of patients with limited independent activities that often present during a critical illness. It is indicative of functional
performance, and particularly the patient’s walking capability, in the ICU at a specific moment in time. Preliminary data suggest that the validity of this tool is supported by expert concurrence, its overall reliability is high, and its clinical use
is acceptable. Kasotakis et al.28 recently reported the use of the RAAS inhibitor Surgical ICU Optimal Mobility Score (SOMS), a simple numeric scale that describes Inhibitors,research,lifescience,medical mobilization capacity of patients and an algorithm developed to select the optimal activity level. The results demonstrated it to be a reliable and valid tool to predict both mortality and ICU/hospital length of stay in surgical critically Inhibitors,research,lifescience,medical ill patients without preexisting impairment of mobility status. Its main use, however, is as an algorithm to advance activity rather than a tool to Inhibitors,research,lifescience,medical measure mobility status, as the Perme
ICU Mobility Score was designed to do. In a retrospective study, Montagnani et al. reported that all 18 items of the FIM could be used as a functional status outcome measure in a small group of patients with a tracheostomy and difficulty weaning from mechanical ventilation.29 While the FIM is possibly suitable Inhibitors,research,lifescience,medical for stable patients in a weaning unit, it has limited validity and usefulness in patients with unstable critical illness or during periods of complex monitoring in the ICU. The FIM has a strong focus on activities of daily living (ADL), which are not commonly performed or expected in the ICU. The Functional Status Score for the Intensive Care Unit (FSS-ICU) included 3 of the 18 FIM items: grooming, bathing, and ambulation. Four other functional tasks relevant to the ICU setting were also included: rolling, transfer from supine to sit, sitting at the edge of bed, and transfer from sit to stand.13 This mix of ADL and ICU activities may lead to low scores Sitaxentan that are not specific to ICU clinician expectations of functional performance. In contrast, all 15 activities in the Perme ICU Mobility Score are feasible for patients in the ICU. Activities such as wheelchair mobility and ADL were not included in the Perme ICU Mobility Score because an expert panel determined that wheelchair mobility activities and independent or assisted self-care activities are not routinely performed in the ICU.
