[Use of diagnostic and therapeutic resources in patients hospitalized for heart failure: influence of admission ward type (INCARGAL Study)].
BACKGROUND
Heart failure (HF) is the most rapidly growing cardiac pathology in industrialized countries, and already the primary cause of hospital admissions of elderly people. Outside the field of clinical trials, there have not been many studies in Spain of the influence of the admission department on diagnostic and therapeutic management, whether this affects short-term and long-term prognosis, and the factors that determine the department the patient is admitted to.


OBJECTIVE
. To analyze whether management and prognosis of patients admitted with heart failure differ depending on the admission ward (cardiology versus internal medicine-geriatrics).


METHODS
Cross-sectional study of 951 patients (505 men and 446 women) consecutively hospitalized for HF in the cardiology (n = 363) and internal medicine-geriatrics (n = 588) wards of 12 hospitals of Galicia and recruited over a maximum period of 6 months. The main epidemiological and clinical variables were recorded at admission, and the complications, treatments, and clinical status were recorded at release.Results. HF patients had a mean age of 75.5 12 years (women 78.5 years and men 72.6 years). The average hospitalization time was 11 8 days and 50.8% were first admissions. Total hospital mortality was 6.8%. Fifty-nine percent (58.9%) of patients had arterial hypertension, 31.9% ischemic heart disease, 27.6% cardiac valve disease, 28.5% diabetes mellitus, and 32.5% chronic obstructive pulmonary disease (COPD). The patients admitted to cardiology ward were younger (72.5 13 vs 77.4 11 years; p < 0.005), more frequently men (51.9 vs 43.7%; p < 0.005), more often first hospitalizations (54.8 vs 48.4%; p < 0.005), and acute pulmonary edema was more common (22.8 vs 9.2%; p < 0.005). The odds ratio (and 95% CI) for therapeutic and diagnostic procedures in relation to admission ward (reference group internal medicine-geriatrics), adjusted for age, sex, systolic function, number of hospitalizations, and history of dementia, hypertension, COPD, AMI, valve disease and ischemic heart disease, are: echocardiogram, 3.49 (2.58-4.73); catheterization, 6.42 (3.29-12.55), admission to intensive care, 3.94 (2.15-7.25), revascularization, 2.15 (0.57-8.08), and beta-blocker treatment, 3.39 (1.93-5.97). No differences in hospital mortality (6.6% in cardiology vs 7% in internal medicine-geriatrics) or average hospitalization time were found between departments.


CONCLUSIONS
The admission ward was related with a clear difference in HF management, with better adherence to guidelines and more use of resources by cardiologists. This was unrelated with differences in hospital mortality so a longer follow-up of these patients is required to evaluate the impact of these therapeutic measures on the prognosis and evolution of HF, as well as the cost-benefit relation in an elderly patient population.
