PREDICTIVE VALUE OF THE MORSE FALL SCALE

Abstract

Aim: The goal of this study was to analyse relevant research studies focusing on the testing of the predictive value of the Morse Fall Scale measuring device on hospitalized patients. Design: Literature review. Method: Search for full text research studies in Web of Science, Scopus, ScienceDirect, and Summon Discovery Tool (licensed electronic information databases), based on pre-established criteria, and key words, from 1989 to 2016. Results: Sensitivity values ranged from 31% to 98%, and specificity values ranged from 8% to 97% in 14 analysed studies. The predictive value of the tool in validation studies varies depending on the tested cut-off value, the type of clinical ward, the frequency of assessment, the size and age of the sample, and the length of hospitalisation; therefore, the validity of the results from one study cannot by extrapolated to the entire hospitalized population of patients. Conclusion: The predictive values of the Morse Fall Scale are not stable; they vary in clinical conditions according to various factors. When implementing a tool for a specific clinical ward, an optimum cut-off score must be established to ensure that preventative strategies do not require unnecessary effort on the part of the staff, and do not increase hospital costs.
