Objective: To describe the characteristics and outcomes of using the Oldfry technology application in older adults, analyzing changes in frailty and fall risk after its implementation. Design and Methods: Observational, analytical, prospective, cross-sectional, and multicenter study conducted in residential centers in Plana Baja (Castellón, Spain). A total of 156 older adults over 65 years old participated, selected based on specific criteria and voluntary consent. Sociodemographic, anthropometric, and clinical variables were collected, including fall history, sensory problems, medication use, and standardized cognitive, nutritional, and functional assessment scales. The study was approved by the Ethics Committee of Universitat Jaume I. Results: The sample included 156 individuals (median age: 84 years). Women showed greater functional dependence (Barthel scale) and cognitive impairment (Pfeiffer scale). The Oldfry device detected frailty with statistically significant differences. A direct relationship was found between greater functional dependence and higher fall risk, as well as between higher comorbidity and increased fall risk. An adequate nutritional status was associated with a lower fall risk. Conclusion: The use of Oldfry is crucial for assessing frailty and fall risk in older adults. Factors such as functionality, comorbidities, and nutritional status directly influence fall prevention, highlighting the importance of technological tools in monitoring these risks.

Antecedentes: El envejecimiento produce un deterioro en la persona mayor y esto afecta el sistema neuromuscular entre otros, reduciendo la masa muscular, la fuerza y la potencia muscular y esto genera una disminución de la capacidad funcional en el adulto mayor, pudiendo ocasionar caídas e incapacidad. Objetivo: El objetivo de este estudio es realizar el pilotaje de una herramienta innovadora para la detección del riesgo de caídas en personas ingresadas en residencias de mayores. Métodos: Los participantes del estudio incluyeron 47 personas mayores (mayores de 55 años) que residían en dos hogares de ancianos. Para conocer el estado previo de los participantes se realizó una Mini-Nutritional Assessment (MNA), escala Charlson y Functional Assessment con FallSkip® en base a los resultados obtenidos por el test de riesgo de caídas Timed Up and Go modificado. Se realizó un análisis descriptivo para observar las diferencias entre residencias mediante la prueba t-student. Resultados: el 70% de las personas en residencias de ancianos tiene más de 75 años, siendo que las participantes del sexo femenino se encontraron mayoritariamente en los grupos de mayor edad, a diferencia de sus homólogos masculinos, que se concentraron en los grupos de menor edad. Al comparar las variables antropométricas y las escalas clínicas de las dos residencias de ancianos no aparecieron diferencias estadísticamente significativas (p > 0,05) solo en la puntuación de riesgo de caída (p < 0,05) y la potencia de sentarse a pararse (p < 0,05).

Objective: To validate the Oldfry instrumental device for efficiently detecting the risk of falls and frailty in older adults. Design and Methods: An observational, analytical, cross-sectional, multicenter, non-randomized study to validate an instrumental device. It was conducted in several nursing homes for the elderly in the province of Castellón, Comunidad Valenciana, Spain, from February to April 2024. The estimated necessary sample size was 149 people. Specific selection criteria and voluntary acceptance to participate in the study were established. Sociodemographic, anthropometric, and other variables such as fall history in the past year were collected. A descriptive and comparative analysis of the variables was performed. The validity and reliability of the device in its measurements were determined to compare the results of the Timed Up and Go (TUG) test and the Short Physical Performance Battery test (SPPB), with respect to the Oldfry instrumental device. Informed consent was obtained from all participants, and the study was approved by the Bioethics Committee of the University Jaume I. Results: The sample consisted of 151 participants with a median age of 84 years (IQR [78.0–91.0]), comprising 39.10% men and 60.90% women, 65 years of age or older. Oldfry presents a sensitivity of 45.90% and a specificity of 72.7% for the risk of falls with a correlation R: 0.773 and an ICC concordance: 0.821. For frailty assessment, it shows a sensitivity of 91.90% and a specificity of 9.10% with an R: 0.854 and ICC: 0.805. Conclusions: This device has proven to be an effective tool for detecting both the risk of falls and frailty in older adults residing in institutions, showing high levels of reliability, sensitivity, and high concordance and correlation in both measurements. Future studies are anticipated to evaluate the benefits of this application.
