Introduction: disorders of consciousness are neurological conditions that may occur following acquired brain injury. They are characterized by an altered level of consciousness and are commonly classified into coma, vegetative state, and minimally conscious state, according to the degree of preserved awareness and responsiveness. The assessment of these conditions relies heavily on the use of standardized evaluation scales, including the Coma Recovery Scale-Revised (CRS-R), the Coma Recovery Scale-Revised for Accelerated Standardized Testing (CRSR-FAST), and the Simplified Evaluation of CONsciousness Disorders (SECONDs). These outcome measures play a crucial role in establishing diagnosis and prognosis, guiding interdisciplinary treatment planning, and evaluating the effectiveness of therapeutic interventions. In order to ensure a more appropriate application and to support the future refinement and adaptation of these assessment tools, it is essential to analyze, synthesize, and compare the methodological quality aspects that characterize them. Such an evaluation can be conducted through the analysis of their measurement properties, as defined by the COnsensus-based Standards for the selection of health Measurement INstruments initiative (2006–2007). Objective: the aim of this bachelor’s thesis is to develop the protocol for conducting a systematic review of the literature, whose objective will be to outline the measurement properties of the CRS-R, CRSR-FAST, and SECONDs in the assessment of patients with disorders of consciousness following severe acquired brain injury. Materials and methods: the protocol for this systematic review was developed in accordance with the 2015 PRISMA-P guidelines, while the reporting of the review will follow the 2024 PRISMA-COSMIN for OMIs recommendations. A comprehensive literature search will be conducted in the following electronic databases: CINAHL, EMBASE (via the Ovid platform), MEDLINE (via the Ovid platform), PsycInfo (via the ProQuest platform), PsycInfo (via the Ovid platform), PubMed, Web of Science. Studies employing any research design will be eligible for inclusion if they report at least one measurement property related to one or more of the following outcome measures used to assess disorders of consciousness in patients with severe acquired brain injury: the CRS-R, the CRSR-FAST, or the SECONDs. Only studies with full texts available in English or Italian will be considered. Data extracted from the included studies will comprise the outcome measures evaluated, their measurement properties, the statistical indices related to the measurement scales, key characteristics of the study populations, and the main methodological features of the studies. Conclusions: this work provides a foundation for the development of a systematic review of the literature concerning the measurement properties of the CRS-R, CRS-R FAST, and SECONDs. Specifically, it outlines the methodological procedures that will be adopted to conduct the proposed research project.
Introduzione: i disturbi di coscienza sono condizioni neurologiche che si possono verificare in seguito a lesioni cerebrali acquisite. Si caratterizzano per un livello alterato di coscienza in base al quale si differenziano in: coma, stato vegetativo e stato di minima coscienza. Per la valutazione di tali disturbi riveste un ruolo importante l’applicazione di scale di valutazione standardizzate come la Coma Recovery Scale-Revised (CRS-R), la Coma Recovery Scale-Revised For Accelerated Standardized Testing (CRSR-FAST) e la Simplified Evaluation of CONsciousness Disorders (SECONDs). Queste misure di outcome permettono di delineare la diagnosi e la prognosi, di pianificare un trattamento interdisciplinare e di valutare l’efficacia dell’intervento terapeutico. Per un utilizzo più appropriato e un futuro perfezionamento e adattamento di tali scale di valutazione è importante analizzare, sintetizzare e confrontare gli aspetti della qualità metodologica che le caratterizzano. Questo è possibile grazie all’analisi delle loro proprietà di misura definite nel 2006-2007 dall’iniziativa COnsensus-based Standards for the selection of health Measurement INstruments. Obiettivo: lo scopo della presente tesi di laurea è redigere il protocollo per la conduzione di una revisione sistematica della letteratura, il cui obiettivo sarà quello di delineare le proprietà di misura della CRS-R, della CRSR-FAST e della SECONDs, nella valutazione dei pazienti con disturbo di coscienza conseguente a grave cerebrolesione acquisita. Materiali e metodi: la stesura del protocollo di questa revisione sistematica rispetta le linee guida PRISMA-P del 2015, mentre la redazione della revisione seguirà le linee guida PRISMA-COSMIN for OMIs del 2024. Sarà condotta una ricerca nelle seguenti banche dati: CINAHL, EMBASE (tramite piattaforma Ovid), MEDLINE (tramite piattaforma Ovid), PsycInfo (tramite piattaforma ProQuest), PsycInfo (tramite piattaforma Ovid), Pubmed, Web of Science. Sarà inclusa ogni tipologia di disegno di studio che riporti almeno una proprietà di misura riferita ad una o più delle seguenti misure di outcome considerate per la valutazione dei disturbi di coscienza nei pazienti con grave cerebrolesione acquisita: CRS-R, CRSR-FAST o la SECONDs. Saranno inoltre selezionati soltanto gli articoli di cui sarà reperibile il testo completo in lingua inglese o italiana. Dagli studi inclusi saranno estratte le misure di outcome prese in esame, le loro proprietà di misura, gli indici statistici delle scale di misura, gli aspetti distintivi della popolazione esaminata e le caratteristiche degli studi. Conclusioni: questo elaborato costituisce un importante punto di partenza per lo sviluppo della revisione sistematica della letteratura relativa alle proprietà di misura della CRS-R, della CRSR-FAST e della SECONDs; sono stati infatti qui definiti i metodi che dovranno essere utilizzati per la realizzazione di tale progetto di ricerca.
