[Predisposing factors of delirium in hip fractured patients older than 84 years]. / Factores favorecedores de la aparición de cuadro confusional agudo en pacientes mayores de 84 años con fractura de fémur.

BACKGROUND AND OBJECTIVE: Our objective was to analyze those factors predisposing to delirium in patients older than 84 years who were admitted because of hip fracture. We also compared the prevalence of delirium in this population with a younger group. PATIENTS AND METHOD: One hundred and thirty patients (mean age 91.8 years) and 50 controls aged 65 to 84 years were included. RESULTS: Forty-three patients (33%) developed delirium. A poor previous functional capacity was the best marker identifying those at risk for developing delirium. Although the prevalence of delirium was higher in those older than 84 years, statistically significant differences were not reached. CONCLUSIONS: Disability prior to admission is the main risk factor predisposing to delirium during hospitalization in patients older than 84 years who are admitted because of hip fracture.

FUNDAMENTO Y OBJETIVO: Estudiar los factores favorecedores de delirium en pacientes mayores de 84 años con fractura de fémur y comparar la frecuencia de aparición con respecto a pacientes más jóvenes. PACIENTES Y MÉTODO: Se evaluó a 130 pacientes (edad media: 91,8 años) ingresados por fractura de fémur y a 50 pacientes control (entre 65 y 84 años de edad). RESULTADOS: Presentaron un episodio de delirium43 pacientes (33%). El mejor indicador para identificar riesgo de delirium es una mala capacidad funcional previa (p =0,001). Aunque el porcentaje de pacientes con delirium es superior en los mayores de84 años, no alcanza significación estadística. CONCLUSIONES: La discapacidad funcional previa es el principal factor que favorece el desarrollo de delirium en los mayores de 84años ingresados por fractura de fémur
