Supplementary Material for: FORTA Score and Negative Outcomes in Older Adults: Insights from Italian Internal Medicine Wards

<b><i>Objectives:</i></b> The study aimed to assess the relationship between the Fit fOR The Aged (FORTA) score – a classification system designed to evaluate medication appropriateness in older adults – and several negative outcomes, including impaired cognitive performance, functional status, adverse clinical events, and all-cause mortality at 3, 6, and 12 months after hospital discharge. <b><i>Methods:</i></b> This retrospective study utilized data from the ELICADHE cohort, a cluster-randomized trial conducted across 20 Italian internal medicine and geriatric wards. The study included patients aged 75 and older with complete FORTA score assessments. Demographics, medication history, and comorbidities were collected. The FORTA classification system assessed medication appropriateness. FORTA scores were calculated and FORTA score cut-offs (3 and 5) were applied. Statistical analyses included descriptive statistics, survival analysis with Cox regression, logistic regression, and negative-binomial regression using SAS 9.4 and RStudio 12.1. Ethical approval was obtained. <b><i>Results:</i></b> Of the 506 patients included, 171 (33.8%) were fully assessable with complete FORTA scores. The study found no significant association between higher FORTA scores and impaired cognitive performance, functional status, or mortality. Additionally, no clear relationship was observed between FORTA scores and adverse clinical events or mortality. The analysis indicated that age was a significant factor associated with mortality and adverse clinical events. <b><i>Conclusion:</i></b> The study did not find a significant relationship between the FORTA score and negative outcomes in older patients discharged from internal medicine and geriatric wards. Further research is needed to define specific FORTA score cut-off values and expand the criteria to improve medication assessment in this population.
