Frailty as a predictor of clinical problems and events that require elderly patients with heart failure to use health resources.

BACKGROUND: The clinical management of elderly patients with heart failure (HF) is not firmly established. Decision-making should be individualized depending on the biological deterioration of each patient, from aggressive management to a palliative approach. Frailty can serve as the basis for this comprehensive individualized management. Our objective was to evaluate the importance of the main clinical problems, as well as the events that required the use of health resources, based the degree of frailty, in elderly patients with HF. METHODS AND RESULTS: Retrospective observational cohort study. Frailty was defined according to the deficit accumulation construct. A total of 546 patients hospitalized for acute HF were included. The median age (Q1-Q3) was 82 (78-86) years. A total of 454 patients (83%) showed some degree of frailty: 221 (48.7%) mild, 207 (45.6%) moderate and 26 (5.7%) advanced. There was a significant tendency towards polypharmacy from no to severe frailty. Hospital events were recorded for 4 (1-6) patients with mild frailty, 4 (2-6) patients with moderate frailty and 2 ((1-4) patients with advanced frailty (p = 0.045). A total of 204 patients (37.4%) died during follow-up. The median time to death was 11.4 (4-16.8), 6.7 (3.3-11.6), 6.5 (3.4-12.2) and 4.1 (0.8-7.7) months for patients with no, mild, moderate, or advanced frailty, respectively (p = 0.006). CONCLUSIONS: Frailty due to deficit accumulation is a good predictor of clinical problems and events that require the use of health resources; therefore, it can serve as a basis for the management of HF in the elderly.

[A reproducibility and validity study of a systematic review on ischemic cardiopathy. The Study Group of the Quality of Care (GRECA)]. / Estudio de la reproducibilidad y validez de una revisión sistemática sobre cardiopatía isquémica. Grupo de Estudio de la Calidad Asistencial (GRECA).

BACKGROUND: The systematic literature reviews have been proposed as a method of scientific evidence identification since they protect the final product from the subjectivity of each primary source reviewer. However, it is not known whether the different ways of evidence synthesis accomplish suitable criteria of objectivity, reliability and biases protection so as to be considered scientifically valid. An experiment of reliability and validity of a systematic literature review about coronary heart disease was carried out. MATERIAL AND METHODS: Study of blind concordance between two independent reviewers for the identification, selection, retrieval and quality evaluation of the articles by using the same protocol. The concordance was analysed by the kappa index for two observers in different categories. The validity was evaluated throughout the acceptability of the review users. RESULTS: The concordance for their identification capacity was poor although they used the same key words (869 versus 476). But the concordance improved when considering selection (26.6% versus 29.2%), retrieval (agreement = 76%) classification by kind of article (kappa = 0.60) and scoring by strength of the evidence (kappa = 0.87). The acceptability was high among review users. CONCLUSIONS: It would be assumed that, even under tight rules of performance, the systematic literature reviews are not completely protected against some biases which could damage their validity in a non easily controllable form. The implication of reviewers, experts in documentation and users of the literature, together with pilot studies performed previous to the review, seems to be the best way to yield better results.

[The special attention to re-admitted patients can be effective. Cost-benefit analysis of a new health care model]. / La atención especial a los pacientes reingresadores puede ser eficiente. Análisis coste-beneficio de un nuevo modelo asistencial.

BACKGROUND: Patients with chronic conditions are commonly readmitted to hospital. A study was designed to improve their medical care. The cost/benefit analysis is presented to evaluate its efficiency. PATIENTS AND METHODS: Patients attended at the Internal Medicine Department in a hospital area who were readmitted three or more times in a year were included in the study. In a prospective study, patients were attended by means of a specific consultation with upon request care or through telephone care, with the possibility of elective admission. A comparison was made of costs of the new care program with costs of their usual care, and it was correlated with attending results. RESULTS: Patients were followed for 32 months with a 45% decrease in admissions, 50% in visits to the Emergency Department, and 26% in the hospital stay days. The new program involves monthly savings over 5 million pesetas for the attended population. CONCLUSIONS: The proposed health care program decreases the attending needs in these patients and costs derived from hospital care. An efficient alternative is shown.

[A new model for medical care to multi-admitted patients]. / Un nuevo modelo para la asistencia a los pacientes multiingresadores.

BACKGROUND AND OBJECTIVE: Patients with chronic conditions are often readmitted to hospital. A study was designed to improve health care to these patients. PATIENTS AND METHODS: Patients attended at the Internal Medicine Department of a hospital area who were admitted to hospital at least three times in a year were included in the study. Within a prospective study, patients were attended by means of specific consultation with care upon request and telephone care, with the possibility of programmed admission. RESULTS: Patients were followed for 32 months, with a 45% decrease in the admission rate, 50% in visits to the Emergency Department, and 26% in hospital stay days. CONCLUSIONS: The proposed care model decrease the attending needs for these patients.

Prospective serological study of leptospirosis in southern Spain.

This article reports data concerning a serosurvey carried out in Southern Spain to assess the current epidemiological status of a population exposed to risk of leptospirosis. Microagglutination and IgM-EIA tests were carried out on sera from a sample of workers in agriculture-related occupations, exposed to marsh waters. A cohort of 197 workers were followed for a year in an active surveillance program to evaluate seroconversion (laboratory confirmed leptospirosis). The results have shown for the cohort a density of incidence: 6.4 x 100 persons per year, and for the reference population an accumulated incidence of 41.25/100,000. Prevalence rates (P) were 21.3 x 100 and 144 x 10(5) for the cohort and population respectively. Rates were higher in cray-fishers (P: 62.7%), rice-workers, and butchers. This is the first report identifying cray-fishers as a high risk group for leptospirosis, and the reporting of human contamination by Australis serogroup in Spain.
