Factores de riesgo y mortalidad hospitalaria de los pacientes quirúrgicos y no quirúrgicos con delirium / Risk Factors and Hospital Mortality in Surgical and Non-surgical Patients with Delirium

resumen Introducción: El delirium es un síndrome neuropsiquiátrico frecuente y con graves consecuencias, especialmente para los pacientes ancianos y con deterioro cognitivo preexistente. Métodos: Estudio descriptivo de una única cohorte retrospectiva. El objetivo es comparar los factores de riesgo y la mortalidad según el tipo de tratamiento (quirúrgico y no quirúrgico) en un grupo de pacientes con delirium hospitalizados. Resultados: Se analizó a 184 pacientes con delirium hospitalizados, por causas quirúrgicas el 29,3% y no quirúrgicas el 70,7%. El 50,5% eran mujeres; el 50% de los pacientes tenían 74 anos o menos (intervalo intercuartílico, 27 arios), con diferencias estadísticas, siendo mayores los no quirúrgicos (p = 0,002). El 42,9% de los pacientes presentaban deterioro cognitivo previo, con mayor proporción entre los no quirúrgicos (el 50,8 frente al 24,1%) y diferencias significativas (p = 0,001). El 89,7% recibía medicamentos anticolinérgicos y el 99,5%, más de 3 medicamentos, sin diferencias significativas. La mitad de los pacientes permanecieron en hospitalización 16,3 días o menos (intervalo intercuartílico, 23 días), y fue significativamente más larga la estancia en el grupo quirúrgico (p < 0,001); el 14,7% de los pacientes murieron en el hospital, sin diferencias estadísticas entre los grupos (p = 0,073). Discusión: No hubo diferencias significativas en la mortalidad entre los grupos, si bien fue mayor en el no quirúrgico (el 17,7 frente al 7,4%). En cuanto a la edad, se encontró que el grupo de mayor mortalidad (el no quirúrgico) tenía una edad y un deterioro cognitivo significativamente mayores, lo cual coincide con la literatura científica.

ABSTRACT Introduction: Delirium is a common neuropsychiatric syndrome with severe consequences, especially for elderly patients with pre-existing cognitive impairment. Methodology: Descriptive study of one retrospective cohort, with the aim of comparing risk factors and mortality between surgical treatment and non-surgical treatment in a group of hospitalised patients with delirium. Results: Of the 184 hospitalised patients with delirium analysed, 29.3% were for surgical causes and 70.7% for non-surgical causes. Just over half (50.5%) were women, and 50% of the patients were 74 years or less (interquartile range, 27 years), with statistical differences (P=.002). Prior cognitive impairment was observed in 42.9% of patients, with a greater proportion of non-surgical (50.8% vs 24.1%) with significant differences (P=.001). Anticholinergic medications were received by 89.7% of patients, and almost all of them (99.5%) received three or more medicines, with no significant differences. Half (50%) of the patients remained in hospital for 16.3 days or less (interquartile range, 23 days). Hospitalisation was significantly longer in the surgical group (P<.001). The hospital mortality was 14.7%, with no statistical differences between groups (P=.073). Discussion: Although there were no significant differences in mortality between the groups, it was higher in the non-surgical (17.7% vs. 7.4%). Increased mortality was found in the older group (non-surgical) that also had significantly greater cognitive impairment, which coincides with that in the scientific literature.

Factors of insulin injection-related knowledge among registered nurses of internal medicine department of Grade 3 generalized hospitals in Shanghai / 现代临床护理

Objective To investigate the insulin injection-related knowledge of the registered nurses in first-class general hospitals in Shanghai and look into its influence factors. Methods Totally 331 nurses in the hospitals were enrolled in this study. Univariate and multivariate stepwise regression were used to analyze the factors which influenced the insulin injection-related . Results The aggregate score of insulin injection-related knowledge was 54.20 ± 7.64, and the score index was 67.75%. Multiple linear regression analysis showed that such factors as professional title and nursing experience and training in the endocrinology department were the main factors of insulin injection-related knowledge (all P<0.05). Conclusion We should enhance the training to promote the injection skills so that they can assist the patients to effectively control blood sugar and improve the quality of life.
