Fall prevention is an essential element in ensuring safe care for paediatric patients. The first step in building a risk reduction programme is the adoption of an assessment tool to identify those most at risk at an early stage. From October 2014 to date, a study has been conducted for the linguistic-cultural validation of the Humpty Dumpty Fall Scale (HDFS) in the Italian context, through a multicentre survey with the help of the Clinical Risk Management Group of the Region of Tuscany.

The objective of this study is the validation of the new Humpty Dumpty Fall Scale defined as Speedy Meyer-Fall Scale (SMFS) by assessing the comprehension and validity of the scale and items via Content Validity Index (SCVI and ICVI) estimation of inter-item reliability (Crombach's alpha), inter-rater reliability (Cohen's K), sensitivity, specificity, PPV, NPV and ROC curve.
