Perme ICU Mobility Score (Perme Score) and the ICU Mobility Scale (IMS): translation and cultural adaptation for the Spanish language.

introductionThe scales to measure functional mobility in critically ill patients were developed and validated in English, there is a need for these tools in Spanish speaking countries.

objectiveTo perform translation, cultural adaptation and inter-rater reliability of the Spanish versions of the Perme Intensive Care Unit Mobility Score and IMS tools in ICU patients.

methodsTranslation and validation study between November 2016 and July 2017, following the COSMIN Protocol's recommendations. Two couples of physiotherapists with the role of observer/rater applied both scales in 150 patients upon admission and discharge of a medical-surgical ICU from a private hospital in Colombia. The sample size was defined taking into account the lowest proportion of reported agreement (68.57%), a Kappa index of 0.2784 or higher to ensure that the calculated n was adequate, and a confidence level of 95.

resultsTranslation and cultural adaptation were performed, the final version of both scales in Spanish was approved by the authors. The sample was 150 patients, 52% were men, the average age was 58 ± 17 years, invasive mechanical ventilation was present in 63 (42%) of the cases. Inter-rater reliability of the ICU Mobility Scale was between 0.97 and 1.00, and for the Perme Intensive Care Unit the Mobility Score it was between 0.99 and 1 in the two moments of the measurements.

conclusionsBoth scales were translated and culturally adapted and presented excellent inter-rater reliability in the two pairs of raters (rater/observer).
