BackgroundIn Italy, the lack of appropriate use of intensive rehabilitative services is an acknowledged issue, as demonstrated by periodic epidemiological surveys. Rehabilitation activities are planned without considering the clinical complexity, known to be one of the most fundamental factors able to outline the real patients' needs on recently clinical practice rehabilitation guidelines. Alternative diagnostic systems become, therefore, necessary. For this reason, we would like to propose the Rehabilitation Complexity Scale - Extended version (RCS-E) within intensive rehabilitation units in Emilia Romagna.AimThis study aims at submitting an Italian translation, cross-cultural adaptation and preliminary reliability evaluation of the Rehabilitation Complexity Scale Extended (13th Version) (RCS-E).DesignFace validity and test-retest reliability.SettingThe study was conducted in three different rehabilitation units of the Emilia Romagna region, Northern Italy.PopulationTen expert physicians and 51 Intensive (code 56) rehabilitation in-patients were recruited.MethodsA cross-cultural adaptation of the scale was built from English into Italian, closely complying with international guidelines. Face validity and test-retest reliability were carried out to evaluate the comprehensibility and goodness of fit of the new scale.ResultsAn overall positive judgement was obtained with the face validity test. No significant differences were observed between the original and the adapted scale scoring. Internal consistency measured on 51 patients by Cronbach's alpha was 0.702 for the scale. The estimated SEM was 1.211. ICCconsistency was 0.702. Split-Half reliability and the Spearman-Brown prophecy were 0.633 and 0.775, respectively. Test-retest reliability of the RCS-E measured with ICCagreement was 0.903.ConclusionThe adapted RCS-E provides a sensitive and reliable tool that appears to be suitable for measuring clinical complexity in Italian code 56 rehabilitation units. It is the first Italian version of the scale to be devised.Clinical Rehabilitation ImpactFurther statistical validation will assess the Italian RCS-E as a possible instrument for guiding the patients' assignment to the rehabilitation settings that best suit their specific needs. These preliminary data represent the first step through this purpose.
