[A case-control study of health benefits in patients with moderate renal failure].
In order to evaluate medical management in patients with renal failure before dialysis, we conducted a case-control study to analyze the health benefits in 914 moderate renal failure patients with Cockcroft clearance between 30 and 60 ml/min. Health benefits reimbursed by the Social Security in this population were compared with those in 1828 controls randomly chosen in the Social Security files but matched by age and gender. Mean age of the participants was 73+/-11 year-old, 67% were women, Cockcroft clearance was 48+/-8 ml/min. Number of hospitalizations and hospitalization durations were not different between the two populations. Conversely, cases had more specialized outpatients' clinics in cardiology but not in nephrology or urology. Cases had more biological tests and radiological exams and had taken more medicines. For biology, cases had more often renal function tests and markers of renal dysfunction tests than controls. Cases had taken more medicines than controls for erythropoietin, diuretics, renin-angiotensin blockers, hypoglycemic drugs, and anticoagulants. Patients with mild renal failure had higher health benefits than controls for outpatients' clinics in cardiology, for biological tests, for radiological exams, and for some medicines.
