BACKGROUND AND AIMS: Atrial fibrillation (AF) is the most common arrhythmia in elderly people, who are particularly exposed to its most severe complications, such as stroke, worsening heart failure and dementia. Some studies demonstrate that AF is associated with increased mortality in home-dwelling subjects, but little is known about the clinical impact of the arrhythmia in hospitalized patients. We studied the clinical associations and effects of AF on the 23,174 hospitalized patients enrolled in the GIFA (Gruppo Italiano di Farmacoepidemiologia nell'Anziano) Study. METHODS: Patients were divided into three groups according to the absence or presence of AF (sinus rhythm, non_AF; AF as main diagnosis, AF_main; AF as comorbid condition, AF_associated) and stratified into four age-groups (< or =60, 61-70, 71-80 and >80 yrs). RESULTS: AF_associated patients were older, more frequently disabled, and characterized by greater comorbidity and longer in-hospital length of stay. Urea nitrogen concentration was higher, and total cholesterol was lower in AF_associated patients, compared with the other two groups. Overall mortality was 6.0%. Mortality was higher in AF_associated patients (non_AF: 6.0% vs AF_associated: 7.1% vs AF_main: 0%, p<0.001). CONCLUSIONS: Our results suggest that, in hospitalized patients, AF as a comorbid condition is associated with worse metabolic profile and clinical outcomes, and thus, may represent a marker of frailty.

Risk factors of functional decline during hospitalization in the oldest old.

BACKGROUND AND AIMS: The number of hospital admissions of the elderly is increasing and hospitalization often leads to functional decline. The aim of this study was to identify major risk factors for functional decline in the hospitalized oldest old. METHODS: Prospective, observational, non-randomized study of patients aged >/=80 years, admitted for at least two days to the University Department of Geriatric Medicine of Torino, Italy, between November 2003 and November 2004. For detection of functional decline, the ADL scale was used, referring to the number of dependent ADL. RESULTS: At discharge, ADL mean scores were significantly higher than on admission (2.5+/-2 vs 2.3+/-1.9, p<0.001). 23.9% of the sample lost at least one ADL function during hospitalization, and 19.2% were transferred to long-term care, compared with 5.4% of those with no functional decline. Length of hospitalization, neoplasm, low level of albumin and high number of drugs prescribed were associated with functional decline. At multivariate analysis, only in-hospital stay was an independent risk factor for functional decline (RR 1.1 per day of hospitalization, CI 1.03-1.14). CONCLUSIONS: Hospitalization of the oldest old increases the risk of functional decline, especially if prolonged. It is important to identify patients at high risk for functional decline after hospital admission.
