The impact of reporting estimated glomerular filtration rate.

The 'Kidney Disease Outcomes Quality Initiative' guidelines recommend laboratory reporting of a calculated estimated glomerular filtration rate (eGFR). The United Kingdom and several states already mandate reporting eGFR for every laboratory serum creatinine (sCr) measurement. In our study, we evaluated the impact of reporting eGFR on the management of hospitalized patients. We reviewed the medical records for 2000 patients, 1000 pre- and 1000 post-reporting eGFR. We excluded patients with previous diagnosis of chronic kidney disease, acute kidney failure, and end-stage renal disease. We analyzed the subgroup of patients with eGFR <60 and sCr <1.5 mg/dL. We did not notice an increase in the number of renal consult, ordering laboratory or imaging study to evaluate chronic kidney disease. The prescription habits did not change for nephrotoxic medications (nonsteroidal anti-inflammatory drugs and aminoglycosides). We did not find any change in the percentage of patients who received hydration for a radiological contrast study or the use of N-acetylcysteine. In conclusion, reporting eGFR did not improve the renal management of hospitalized patients.
