[Prognostic value of the primary diagnosis in elderly patients admitted to an acute geriatric unit at discharge and one year later]. / Valor pronóstico del diagnóstico principal en ancianos ingresados en una unidad geriátrica de agudos al alta y al año.

OBJECTIVE: To analyse the relationship between the primary diagnosis on admission to an Acute Geriatric Unit (AGU) and the risk of hospital mortality and one year after discharge MATERIAL AND METHODS: A longitudinal study was conducted on patients admitted to the Central Hospital AGU Red Cross in Madrid in 2009. The admission diagnosis was grouped by Diagnosis Related Groups (DRGs). The date of death was collected from the medical charts and the National Death Index Ministry of Health report. The main outcome of study was the association between diagnoses on admission and functional impairment at discharge (measured as a loss of 10 or more points between the Barthel Index at discharge and that on admission), mortality during hospitalization, at 3 months and one year after discharge. The multivariate analysis was adjusted for age, sex, comorbidity, functional and cognitive status, and serum albumin. RESULTS: The study included1147 patients, with a mean age of 86.7 years (SD±6.7), and 66% were women. During admission, 10.1% of patients died and 36.6% had functional impairment at discharge. After discharge, 25.5% died at 3 months, and 42.2% at one year. The distribution of the primary diagnoses at admission (between parentheses hospital mortality and at year) were heart failure, 21.4% (8.1% and 37.4%), pneumonia,13.3% (12.3% and 46.4%), and aspiration pneumonia, 4.7% (27.5%, y 71%), respiratory diseases,13.3% (6.6% and 38.2%), urinary infection,10.2% (5.1% and 42.7%), and stroke (excluding AIT), 9.9% (13.3% and 46.9%). In the multivariate analysis, only admissions due to aspiration pneumonia were independently associated with increased risk of hospital mortality (odds ratio, 2.23; 95% CI=1.13 to 44.42), and stroke with increased risk of functional impairment at discharge (odds ratio, 6.01; 95% CI=3.42-10.57). No diagnosis was independently associated with increased risk of death at 3 months and at year CONCLUSIONS: Admission from aspiration pneumonia carries an increased risk of death in elderly patients hospitalised for acute medical conditions. After discharge, the risk of death must be attributed to factors other than the admission diagnosis.

[Which patients benefit the most from hospital geriatric care in the opinion of the geriatricians?]. / ¿Qué pacientes se benefician más de la atención geriátrica hospitalaria en opinión de los especialistas en Geriatría?

OBJECTIVE: To assess the most appropriate criteria considered by geriatricians to select patients who might benefit the most from geriatric hospital care. MATERIAL AND METHODS: We carried out a survey that consisted of various socio-demographic, clinical, functional and mental criteria included in the definition of the geriatric and frail elderly patient. The survey was sent to all specialists in geriatrics in the different hospitals of the Madrid Health Service. They were asked to answer to each criterion indicating whether they considered it as high priority, priority, low priority or no priority. The responses were clustered by type of hospital: acute hospitals with or without a post-graduate geriatric program for medical residents, and medium and long stay hospitals. RESULTS: A total of 83 questionnaires were completed (70% of the study population): 42 teaching hospitals a post-graduate geriatric program (74% of possible), 20 of those with an emergency department but without a post-graduate geriatric program (56% of possible), and 21 medium and long stay hospitals (84% of potential). All proposed criteria were considered individually as priority or high-priority by more than 50% of respondents. An age 85 years and over, admission for hip fracture, the presence of severe cognitive or functional impairment, frailty, and unexplained deterioration of health status, were considered individually as criteria for selecting high-priority target population by more than 85% of respondents. CONCLUSIONS: Certain criteria, such as advanced age, or the presence of geriatrics-specific conditions, such as hip fracture or severe functional or cognitive impairment, are identified by geriatricians as useful to select patients to receive geriatric specialist hospital care.

[Renal function evaluation methods in the elderly: reliability and clinical implications]. / Métodos de evaluación de la función renal en el paciente anciano: fiabilidad e implicaciones clínicas.

Chronic renal disease (CRD) is found in a third of the Spanish population aged more than 65 years old. Detection and early treatment would increase survival and help to reduce associated cardiovascular morbidity and mortality as well as the risk of pharmacological iatrogeny. Determination of the glomerular filtration rate has traditionally been considered the best parameter for renal function evaluation, which should not be based exclusively on serum creatinine concentration or creatinine clearance. The application of predictive equations is useful in the diagnosis, classification and outpatient management of patients with CRD. Most studies performed in the elderly have found that the Modification of Diet in Renal Disease (MDRD-4) has greater precision and accuracy than the Cockcroft-Gault formula, and is considered the nomogram of choice in this age group. The Cockcroft-Gault formula can be used when rapid estimation of renal function or drug adjustments are required, so long as the limitations of this method are taken into account.
