Comorbid conditions that develop during chronic renal insufficiency (CRI) c
ontribute to the high morbidity and mortality among patients with end-stage
renal disease (ESRD). Thus, appropriate management during CRI may lead to
improved ESRD outcomes. A retrospective cohort study was performed to descr
ibe the management of patients with CRI. A total of 602 patients with CRI (
creatinine greater than or equal to1.5 mg/dl for women and greater than or
equal to2.0 mg/dl for men) were seen between October 1994 and September 199
8 at five nephrology outpatient clinics in the Boston area. The mean (SD) a
ge of the patients was 63 (15.5) yr, and 53% were male. At the first nephro
logy visit, mean (SD) serum creatinine was 3.2 (1.6) mg/dl, and mean (SD) p
redicted GFR was 22.3 (8.9) ml/min per 1.73 m(2). Laboratory tests for iron
levels were performed in only 18% of patients, serum parathyroid hormone l
evels were obtained in only 15%, lipid studies were obtained in fewer than
half, and among patients with diabetes, only 28% had a glycosylated hemoglo
bin level measured. A hematocrit <30% was present in 38%, and abnormal calc
ium-phosphorus metabolism was noted in 55%. Only 59% of patients who had he
matocrit <30%, received recombinant human erythropoietin. Among patients wh
o received recombinant human erythropoietin, only 47% received iron. Angiot
ensin-converting enzyme inhibitor use was recorded for only 65% of patients
with diabetes (49% of patients overall). Among patients who were known to
have progressed to ESRD, only 41% had permanent access placed before initia
tion of dialysis. There seems to be room for improvement in the management
of patients with CRI, which could result in a slower rate of progression of
CRI and reduced severity of comorbid conditions.
