Mortality and associated risk factors for older adults admitted to the emergency department: a hospital cohort.

BACKGROUND: Older emergency department patients are more vulnerable than younger patients, yet many risk factors that contribute to the mortality of older patients remain unclear and under investigation. This study endeavored to determine mortality and factors associated with mortality in patients over 60 years of age who were admitted to the emergency departments of two general hospitals in Mexico City. METHODS: This is a hospital cohort study involving adults over 60 years of age admitted to the emergency department and who are beneficiaries of the Mexican Institute of Social Security and residents of Mexico City. All causes of mortality from the time of emergency department admission until a follow-up home visit after discharge were measured. Included risk factors were: socio-demographic, health-care related, mental and physical variables, and in-hospital care-related. Survival functions were estimated using Kaplan-Meier curves. Hazard ratios (HR) were derived from Cox regression models in a multivariate analysis. RESULTS: From the 1406 older adults who participated in this study, 306 (21.8%) did not survive. Independent mortality risk factors found in the last Cox model were age (HR = 1.02, 95% CI, 1.005-1.04; p = 0.01), length of stay in the ED (HR = 1.003, 95% CI = 0.99, 1.04; p = 0.006), geriatric care trained residents model in Hospital A (protective factor) (HR = 0.66, 95% CI = 0.46, 0.96; p = 0.031), and the FRAIL scale (HR of 1.34 95% CI, 1.02-1.76; p = 0.033). CONCLUSIONS: Risk factors for mortality in patients treated at Mexican emergency departments are length of stay and variables related to frailty status.

Clinical effectiveness of group cognitive-behavioural therapy for depressed older people in primary care: A randomised controlled trial / Eficacia clínica de una terapia cognitivo-conductual en grupo para personas mayores con depresión en Atención primaria: Un ensayo aleatorio controlado

Background Depression is associated with an increased use of medical resources and reduced quality of life, cognitive functions, functionality and general health. The treatment of depression is limited by the scarcity of mental health professionals, as reflected in the mental health atlas of the World Health Organization. Method A randomised controlled trial that was not blinded was conducted. Family doctors referred patients older than 60 years who were suspected to have depression to the screening module. The PHQ-9 questionnaire, the Six-Item Screener, and previous diagnosis for psychiatric disorders were collected. Major depression was excluded. Those with a score from two to six on the PHQ-9 and with no comorbidities were referred to the Baseline Phase. A simple random process without blocking was applied. Groups of 7-10 participants engaged in weekly sessions over the course of three months. The control group was referred to their family physician. Reduction in depression score of the PHQ-9 was the main outcome. Results and discussion There were 40 patients in the control group (CG) and 41 in the intervention group (IG). 84% were women, 41% married and 41% reported at least primary education. The mean age for the GC was 69.7 years vs. 71.3 in the GI. The baseline mean MMSE score was 23.7 in the GC and 24.1 in the IG. No significant baseline differences between groups were reported. In the IG, 56% of the participants (n=23) displayed a decrease that was greater than or equal to 5 points on the PHQ-9 compared with 30% (n=12) in the control group. The CT group evidenced a marginal improvement.

Antecedentes La depresión se asocia con un aumento en el uso de los recursos médicos y reducción de la calidad de vida, funciones cognitivas, funcionalidad y la salud general. El tratamiento de la depresión está limitado por la escasez de profesionales en salud mental, como se refleja en el atlas de salud mental de la Organización Mundial de la Salud. Método Se realizó un ensayo controlado aleatorio no cegado. Los médicos familiares referían a los pacientes mayores de 60 años con sospecha de depresión al módulo de detección. Se aplicó el cuestionario PHQ-9, la prueba de escrutinio de seis ítems, y el diagnóstico previo de trastornos psiquiátricos. Se excluyó a pacientes con depresión mayor. Aquellos con una puntuación de dos a seis en el PHQ-9 y sin comorbilidades fueron remitidos a la fase basal. Se aplicó un proceso aleatorio simple sin bloquear. Se integraron grupos de 7-10 participantes en sesiones semanales durante el transcurso de tres meses. El grupo control fue remitido a su médico familiar. El resultado principal fue la reducción en la puntuación de la depresión del PHQ-9 Resultados y discusión Se estudiaron a 40 pacientes en el grupo control (GC) y 41 en el grupo intervención (GI). 84% eran mujeres, 41% casados y el 41% informó de al menos la educación primaria. La edad media para el GC fue 69.7 años vs. 71.3 en el GI. La puntuación media del MMSE fue de 23.7 en el GC y el 24.1 en el IG. No se registraron diferencias iniciales significativas entre los grupos. El 56% de los participantes del GI mostró una disminución que fue mayor que o igual a cinco puntos en el PHQ-9 en comparación con 30% del GC. El grupo CT demuestra una mejora marginal.
