equations (around 41.2%), although percentages of patients with stages 2, 4 and 5 were increased in women with the CKD-EPI equation. Apart from this, the results for men and women are essentially analogous for each age group. However, although eGFRs are generally lower in both men and women aged over 70 with the CKD-EPI The rate therefore measured is the quantity of the substance in the urine that originated from a calculable volume of blood. Relating this principle to the below equation – for the substance used, the product of urine concentration and urine flow equals the mass of substance excreted during the time that urine has been collected. 2020-08-12 · The CKD-EPI equation performed better than the MDRD (Modification of Diet in Renal Disease Study) equation, especially at higher GFR, with less bias and greater accuracy. When looking at NHANES (National Health and Nutrition Examination Survey) data, the median estimated GFR was 94.5 mL/min per 1.73 m 2 vs. 85.0 mL/min per 1.73 m 2 , and the prevalence of chronic kidney disease was 11.5% The CKD-EPI equation performed better than the MDRD (Modification of Diet in Renal Disease Study) equation, especially at higher GFR, with less bias and greater accuracy.

Multiple studies have compared the equations for their impact on drug dosages. In the few studies that compared estimated GFR from the various equations to measured GFR, the studies have shown that the MDRD Study or CKD-EPI equation had greater concordance with measured GFR than the Cockcroft-Gault. The MDRD Study equation and more recently the CKD-EPI equation have been shown to be more accurate than the Cockcroft and Gault equation; The MDRD Study and CKD-EPI equations are now more widely reported automatically by clinical laboratories every time a creatinine is measured; Creatinine assays are standardized to reference methods. Both the MDRD Study and CKD-EPI have been expressed for these reference methods, but The Cockcroft and Gault has not. The CKD-EPI equation was developed in 2009 using a diverse population estimate GFR from serum creatinine, age, sex and race. The CKD-EPI equation is as accurate as the MDRD Study equation (currently reported by laboratories) in the subgroup with estimated GFR less than 60 mL/min/1.73 m 2 and substantially more accurate in the subgroup with estimated GFR greater than 60 ml/min/1.73 m 2 .

- "Evaluation of 'CKD-EPI Pakistan' Equation for estimated Glomerular Filtration Rate (eGFR): AComparison of eGFR Prediction Equations in Pakistani Population." 2017-9-7 · "CONCLUSION: The CKD-EPI creatinine equation is more accurate than the Modification of Diet in Renal Disease Study equation and could replace it for routine clinical use." 1. Reference: 1. Levey AS, Stevens LA, Schmid CH, Zhang YL, Castro AF 3rd, Feldman HI, Kusek JW, Eggers P, Van Lente F, Greene T, Coresh J. The CKD-EPI creatinine-based estimation equation for glomerular filtration rate (GFR) cannot be used in children, overestimates GFR in young adults, and its combination with the KDIGO recommended pediatric CKiD (Schwartz bedside) equation causes implausible increases in estimated GFR when switching from pediatric to adult care.

### Glomerular filtration rate (GFR) is the best overall index of kidney function. Normal GFR varies according to age, sex, and body size, and declines with age. The National Kidney Foundation recommends using the CKD-EPI Creatinine Equation (2009) to estimate GFR.

Apart from this, the results for men and women are essentially analogous for each age group. However, although eGFRs are generally lower in both men and women aged over 70 with the CKD-EPI formula, the increase in CKD stages 3 e 5 in this age group is due to an increase in the number of men rather than women. 2015-12-1 · Of these equations, the CKD-EPI equation that combines creatinine and cystatin C (CKD-EPI-Cr-CysC) showed a bias of 0.12 ml/min/1.73 m(2) as compared to measured GFR. CONCLUSIONS: The CKD-EPI equation that combines serum creatinine and cystatin C measurements shows the best performance for accurate estimation of GFR in cirrhosis, especially at The CKD‐EPI equation correlates better with ganciclovir clearance than the Cockcroft‐Gault and MDRD4‐IDMS equations, even the clinical difference between the equations is scarce. What is Already Known about this Subject. The dose adjustment of ganciclovir in renal failure, like most drugs, is currently done according to creatinine 2016-3-28 report eGFR creat in adults using the 2009 CKD-EPI creatinine equation. An alternative creatinine-based GFR estimating equation is acceptable if it has been shown to improve accuracy of GFR estimates compared to the 2009 CKD-EPI creatinine equation.

85.0 mL/min per 1.73 m 2 , and the prevalence of chronic kidney disease was 11.5% 2012-05-29 · The CKD-EPI equation more appropriately categorized individuals with respect to long-term clinical risk compared with the MDRD equation, suggesting improved clinical usefulness in this middle-aged bi-ethnic population in the United States. Gary Theilman, Pharm.D.University of Mississippi School of Pharmacy 2017-09-07 · Current equations have limited precision and systematically underestimate measured GFR at higher values." 1 "CONCLUSION: The CKD-EPI creatinine equation is more accurate than the Modification of Diet in Renal Disease Study equation and could replace it for routine clinical use." 1. Reference: 1. 2017-02-10 · The CKD-EPI equation gave somewhat higher eGFR estimates than the MDRD formula (95.2 mL/min/1.73 m 2 and 90.4 mL/min/1.73 m 2 by CKD-EPI and MDRD creatinine equations, respectively; p < 0.001), resulting in smaller but non-significant numbers of patients with eGFR <90 mL/min/1.73 m 2 (27.4% vs.

2012-05-29 · KM: The original paper of the CKD-EPI equation was published in 2009 in the Annals of Internal Medicine. The equation was developed and validated in approximately 12,000 individuals with both measured and estimated GFR from 26 studies.

2016-03-29 · Therefore, in the CKD-EPI equation, the use of age leads to an overestimation of GFR in children, adolescents, and young adults, whereas, in people ≥65 y old, the CKD-EPI equation performs better than the Schwartz equation whatever the GFR level because of the significant muscle mass decrease.

MDRD STUDY EQUATION: mdrd (Age, Race, Gender, Plasma creatinine) Chronic kidney disease (GFR less than 60 or kidney damage for at least three months) The National Kidney Foundation recommends using the CKD-EPI Creatinine Equation (2009) to estimate GFR. NKF and the American Society of Nephrology have convened a Task Force to focus on the use of race to estimate GFR. Read more about the task force here. 2015-12-3 · Unlike the MDRD equation, the CKD-EPI equation also contains a spline term for serum creatinine (at 62 μmol/L for females and 80 μmol/L for males) to account for the weaker relationship between serum creatinine and GFR at lower compared with higher creatinine levels [ 4, 5 ]. 2011-11-1 The CKD-EPI equation may be preferred in screenings of general populations and in the elderly. None of the equations appeared reliable among patients with markedly decreased GFR, young adults and 2016-3-29 · Among several GFR estimating equations, the Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) equation has been recommended in adults, and the Schwartz equation in children [ 3, 4, 7, 8] (Table 1). The CKD-EPI equation does require race (African American or non-African American), which also may not be readily available.
