Características clínicas y evolución del paciente anciano mayor de 80 años en una Unidad de Cuidados Intensivos / Clinical features and disease progression of elderlypatients at the ICU setting

Objetivo Describir y caracterizar una cohorte de pacientes octogenarios ingresados en la UCI del Hospital Universitario Central de Asturias (HUCA). Diseño Estudio retrospectivo, observacional y descriptivo de 14 meses de duración. Ámbito Unidad de Cuidados Intensivos (UCI) Cardiaca y UCI Polivalente del Servicio de Medicina Intensiva del HUCA (Oviedo). Participantes Pacientes mayores de 80 años que ingresaron en la UCI durante más de 24 horas.Intervenciones Ninguna. Variables de interés principales Edad, sexo, comorbilidad, capacidad funcional, tratamiento, complicaciones, evolución, mortalidad. Resultados Los motivos de ingreso más frecuentes fueron la cirugía cardiaca y la neumonía. La estancia media de ingreso fue significativamente mayor en pacientes menores de 85 años (p=0,037). El 84,3% de estos últimos se benefició de ventilación mecánica invasiva (VMI) vs. 46,2% de los pacientes más mayores (p=<0,001). Los pacientes mayores de 85 años presentaron mayor fragilidad. El ingreso por intervención quirúrgica cardiaca se asoció con menor riesgo de mortalidad (hazard ratio [HR]=0,18; intervalo de confianza [IC] 95%, 0,062-0,527; p=0,002). Conclusiones Los resultados muestran una asociación entre el motivo de ingreso en UCI y el riesgo de mortalidad en pacientes octogenarios. La cirugía cardiaca se asoció con mejor pronóstico frente a la patología médica, donde la neumonía se asoció con mayor riesgo de mortalidad. Además, se observó una relación positiva significativa entre edad y fragilidad. (AU)

ObjectiveTo describe and characterize a cohort of octogenarian patients admitted to the ICU of the University Central Hospital of Asturias (HUCA). Design Retrospective, observational and descriptive study of 14 months’ duration. Setting Cardiac and Medical Intensive Care Units (ICU) of the HUCA (Oviedo). Participants Patients over 80 years old who were admitted to the ICU for more than 24hours. Interventions None. Main variables of interest Age, sex, comorbidity, functional dependence, treatment, complications, evolution, mortality. Results The most frequent reasons for admission were cardiac surgery and pneumonia. The average admission stay was significantly longer in patients under 85 years of age (p=0,037). 84,3% of the latter benefited from invasive mechanical ventilation compared to 46,2% of older patients (p=<0,001). Patients over 85 years of age presented greater fragility. Admission for cardiac surgery was associated with a lower risk of mortality (HR=0,18; 95% CI (0,062-0,527; p=0,002). Conclusions The results have shown an association between the reason for admission to the ICU and the risk of mortality in octogenarian patients. Cardiac surgery was associated with a better prognosis compared to medical pathology, where pneumonia was associated with a higher risk of mortality. Furthermore, a significant positive association was observed between age and frailty. (AU)

Clinical features and disease progression of elderly patients at the ICU setting.

OBJECTIVE: To describe and characterize a cohort of octogenarian patients admitted to the ICU of the University Central Hospital of Asturias (HUCA). DESIGN: Retrospective, observational and descriptive study of 14 months' duration. SETTING: Cardiac and Medical intensive care units (ICU) of the HUCA (Oviedo). PARTICIPANTS: Patients over 80 years old who were admitted to the ICU for more than 24 h. INTERVENTIONS: None. MAIN VARIABLES OF INTEREST: Age, sex, comorbidity, functional dependence, treatment, complications, evolution, mortality. RESULTS: The most frequent reasons for admission were cardiac surgery and pneumonia. The average admission stay was significantly longer in patients under 85 years of age (p = 0,037). 84,3% of the latter benefited from invasive mechanical ventilation compared to 46,2% of older patients (p = <0,001). Patients over 85 years of age presented greater fragility. Admission for cardiac surgery was associated with a lower risk of mortality (HR = 0,18; 95% CI (0,062-0,527; p = 0,002). CONCLUSIONS: The results have shown an association between the reason for admission to the ICU and the risk of mortality in octogenarian patients. Cardiac surgery was associated with a better prognosis compared to medical pathology, where pneumonia was associated with a higher risk of mortality. Furthermore, a significant positive association was observed between age and frailty.
