The elderly are the fastest growing segment of the United States population. Age is a key predictor of chronic kidney disease (CKD). A major obstacle in the recognition of CKD in the elderly is the reliance on serum creatinine measurements as an estimation of glomerular filtration rate (GFR). We hypothesized that early stages of CKD would not be recognized by primary care clinicians providing care to elderly men in a highly structured setting. This study was a retrospective study of outpatients 70 years and older seen in VISN 9 at Veterans Administration Medical Centers from 1/1/2001 thru 12/31/2003. GFR was estimated using the MDRD formula. We abstracted demographic and medical data from the electronic medical record. The population consisted primarily of elderly white male (7,289 men; 91% Caucasian). In CKD Stage 2, 3, and 4, men had a diagnosis code reflecting kidney disease in 1.2%, 20%, and 74.6% of the charts. Despite declining kidney function, nephrology consults were requested in fewer than 5%. In summary, we have shown in a large outpatient population of elderly men that CKD is frequently under-recognized, but most pronounced in CKD Stages 2 and 3. Stages 2 and 3 may be the stages in which the most beneficial effects of interventions can be obtained.
