Prevalence and factors associated with chronic kidney disease among hospitalized patients in a university hospital in the city of São Paulo, SP, Brazil.
BACKGROUND
Chronic kidney disease (CKD) is a major public health problem worldwide. Nonetheless, little is known about its features in Brazil.


OBJECTIVE
To identify prevalence and factors associated with CKD among hospitalized patients in a university hospital.


METHODS
We randomly selected 826 medical records of patients admitted in 2009 in the medical inpatient unit. We defined CKD as the presence of medical diagnosis or personal history. We collected a number of clinical and demographic information and these variables were compared between patients with and without CKD.


RESULTS
CKD prevalence was 12.7%. Patients with CKD differed from patients without (p < 0.05) regarding to: living with a partner (59.8% vs. 47.3%), older age (65.8 ± 15.6 vs. 55.3 ± 18.9 years-old), more comorbidities as hypertension (75.2% vs. 46.3%), diabetes (49.5% vs. 22.4%), dyslipidemia (23.8% vs. 14.9%), acute myocardial infarction (14.3% vs. 6.0%) and congestive heart failure (18.1% vs. 4.3%); length of hospitalization (11 (8-18) vs. 9 (6-12) days); and death occurrence (12.4% vs. 1.4%). The logistic regression analysis showed an independent association (OR, odds ratio, CI, confidence interval 95%) of CKD with age (OR 1.019, CI 1.003 to 1.036), hypertension (OR 2.032, CI 1.128 to 3.660), diabetes (OR 2.097, CI 1.232 to 3.570) and congestive heart failure (OR 2.665, CI 1.173 to 6.056).


CONCLUSIONS
CKD prevalence among patients in a medical inpatient unit was high and CKD patients were more complex, as they were older and had a great number of co-morbidities, reflecting a greater risk of death during hospitalization.
