Correlation of Estimated Creatinine Clearance and Glomerular Filtration Rate in Very Elderly Patients and Antibiotic Prescribing Errors: Cohort Study

Introduction: Determination of renal function is particularly important when prescribing antibiotics to elderly patients. This study aims determine the correlation between estimated creatinine clearance and glomerular filtration rate, for a hospitalized population very patients, audit antibiotic errors.Material Methods: Retrospective cohort all patients ? 80 years with antibiotic. Creatinine was calculated using Cockcroft-Gault equation rate by Modification Diet in Renal Disease Study Chronic Kidney Epidemiology Collaboration equations. Dosing errors were determined through adjustment daily define dose function.Results: The included 589 r = 0.98 0.96 minimum serum creatinine, 0.97 0.93 maximum creatinine. Based on Cockcroft-Gault, there defined 45% 52% day. There discrepancy recording 14% 16% compared Collaboration.Discussion: good or Collaboration. Regardless used estimate high dosing documented this population.Conclusion: supports maintenance drug population. Further studies are needed investigate underlying causes errors.
