Health care resource utilization and the impact of anemia management in patients with chronic kidney disease.

ABSTRACT

BACKGROUND: Limited information exists on resource utilization patterns and overall patient management of chronic kidney disease (CKD) before the initiation of dialysis therapy. METHODS: A retrospective claims analysis from January 1997 to December 1999 was conducted using a managed care database on 1,936 incident dialysis patients, examining the 12 months preceding dialysis initiation to evaluate whether managed care patients with CKD are receiving expected interventions and appropriate management of CKD. RESULTS: Mean age was 66.8 years, 46% were women, 91.2% had claims for facility services, 97.6% had claims for professional services, and 95.7% had claims for outpatient pharmacy, with mean costs per patient of $26,204, $9,623, and $1,503, respectively. Sixty-two percent of patients were hospitalized, averaging 1.3 admissions annually ($14,818/admission; average, 7.8 d/admission). Despite high overall resource use, treatments for preparation for dialysis therapy, appropriate tests, and nutritional supplements (eg, phosphate binders, B-complex combinations, and vitamins with iron) were administered infrequently. Comorbid conditions, such as anemia (47.4%) and diabetes (53%), were appropriately addressed with erythropoietin (10.5%) and angiotensin-converting enzyme inhibitors (38%) in only a minority of cases. In preparation for dialysis therapy, only 20.8% underwent a vascular access procedure. CONCLUSION: Although patients consumed significant amounts of resources during the 12 months before dialysis initiation, many were not using expected resources for the appropriate management of CKD. A number of opportunities exist to improve predialysis care through better management of these conditions.
