Augmented Nurse Care Management in CKD Stages 4 to 5: A Randomized Trial

Abstract

Background: Outcomes for patients with late-stage chronic kidney disease (CKD) in the United States are suboptimal. There is poor education and preparation for end-stage kidney disease, as well as a high rate of hospitalization in this group of patients.

Study design: A randomized, parallel-group, 2-arm, controlled trial.

Setting & participants: The study was conducted at 3 sites: a clinic of an academic medical center, a public hospital academic clinic, and a community-based private practice. All participants had late-stage CKD (stages 4-5 CKD). Patients were excluded only if they had significant cognitive impairment.

Intervention: The care management intervention involved nurse care manager coordination aided by the use of a disease-based informatics system for monitoring patients' clinical status, enhancing CKD education, and facilitating preparation for end-stage kidney disease. The comparison control group received usual late-stage CKD care alone.

Outcomes: The primary outcome was rate of hospitalization.

Measurements: Rates of preemptive transplantation, home dialysis, hemodialysis (HD) starts without a hospitalization, and HD therapy initiation rates with catheters or with functioning accesses.

Results: 130 patients were randomly assigned. The hospitalization rate was significantly lower in the intervention group versus controls: 0.61 versus 0.92 per year, respectively (incidence rate ratio, 0.66; 95% CI, 0.43-0.99; P=0.04). Peritoneal dialysis or preemptive transplantation was the initial end-stage kidney disease treatment in 11 of 30 (37%) participants receiving the intervention versus 3 of 29 (10%) receiving usual care. Among HD starts, treatment was initiated without hospitalization in 11 of 19 (58%) participants in the intervention group versus 6 of 26 (23%) in the control group. At the time of HD therapy initiation, a catheter was present in 7 of 19 (37%) participants in the intervention group versus 18 of 26 (69%) in the control group. A functioning arteriovenous access was in place in 10 of 19 (53%) participants in the intervention group and 7 of 26 (27%) in the control group LIMITATIONS: Moderate sample size, limited geographic scope.

Conclusions: The augmented nurse care management intervention resulted in reduced hospitalizations in late-stage CKD and there were suggestions of improved end-stage kidney disease preparation. Given suboptimal outcomes in late-stage CKD, care management interventions could potentially improve patient outcomes.
