title: [Activity in a nephrology ward in 2009, Piemonte, Italy].
abstract: The characteristics of patients hospitalized in nephrology wards in Italy have changed in recent years due to the aging Italian population and the increased immigration. We analyzed the demographic and clinical characteristics of patients hospitalized in our nephrology ward (17 beds) from 15 November 2008 to 15 November 2009. In this period there were 507 hospitalizations including 448 patients. The mean age was 64.4+/-18 years (range 16-96 years). Foreigners accounted for 10% of the total; their mean age was significantly lower than that of Italian patients (38.2+/-13.4 vs 67.4+/-15.9 years, p<0.01). 36.3% of patients were on dialysis, 10% were transplant recipients: the reasons for admission in these cases were internal medicine related; 18.15% were hospitalized because of emergency unit crowding without indications for admission to a nephrology ward. Hospitalization lasted a mean of 13+/-13 days. The most frequent diagnosis at discharge was acute renal failure (ARF) (28.9%) (prerenal 42.1%, obstructive 12.2%, drug induced 6.8%, other causes of ARF 38.7%). Patients with ARF were older than patients with other kidney conditions (67.05+/-16.98 vs 56.03+/-18.65 years, p<0.01). ARF resolved or improved in 86 patients (63.7%). Other diagnoses were cardiovascular disease 25.1%, glomerular disease 18.7%, acute pyelonephritis 10.6%, other 16.7%. Foreign patients presented infectionrelated diseases more often than Italian patients (39.2% vs 20.4%, p=0.02). 392 patients were discharged to their homes, 40 (7.9%) found a place in a long-term care facility or home for the elderly, 25 (4.9%) in other hospital units, and 50 patients died (9.8%). In conclusion, patients hospitalized in nephrology wards in 2009 were mostly elderly with a high frequency of cardiovascular disease and diabetes. The most frequent diagnosis was prerenal ARF. These data suggest the necessity of improving the prevention of this type of kidney disease. Moreover, the length of hospitalization, which is increasing because of difficult clinical and social situations, could be shortened if more nursing homes, convalescent homes and homes for the elderly were available in Italy.
