INFLUENCIA DE FACTORES CLÍNICOS EN LA LESIÓN RENAL AGUDA

Abstract

Objective: To verify the relationship between variations in creatinine clearance (ClCr) and clinical factors in hospitalized patients in internal medicine. Material and Method: A prospective, quantitative, cohort study conducted at the medical clinic of a public hospital in Distrito Federal. 85 patients progressed with Acute Kidney Injury (AKI), according to the Kidney Disease Improving Glogal Guidelines (KDIGO) classification. Patients were followed-up to 1 month after hospital discharge. Patient severity was measured using the Charlson Comorbidity Index. Results with p ? 0.05 were considered significant. Results: 51.8% of the patients were male. Most common comorbidities were hypertension (70.6%), diabetes mellitus (57.6%) and heart disease (52.9%). 6 e length of hospital stay (p = 0.001) and age (p = 0.05) were associated with worse renal function. Patients with CrCl ? 30 ml/min were associated with a higher mortality rate (p = 0.007). Conclusion: Older patients and longer hospital stay were associated with worsening renal function (CrCl < 60 ml/min). Those with severe worsening of renal function (CrCl < 30 ml/min) presented higher mortality rate.
