Goal attainment and renal outcomes in patients enrolled in the chronic kidney disease care program in Taiwan: a 3-year observational study.

Objective: To analyze the effects of chronic kidney disease (CKD) care programs on clinical outcomes.

Design: An observational, retrospective study with medical record review.

Setting: Kaohsiung Chang Gung Memorial Hospital.

Participants: Patients diagnosed with CKD.

Interventions: CKD care programs conducted by nephrologists-based team from 2006 to 2013 in our hospital.

Main Outcome Measures: We set 10 goals with treatment target ranges based on the guidelines suggested by the following organizations: Kidney Disease Improving Global Outcomes (2012) and the National Kidney Foundation Kidney Disease Outcomes Quality Initiative (2003).

Results: In total, 1486 patients were enrolled. Their average estimated glomerular filtration rate (ml/min/1.73 m2) was 31.9 at baseline and declined to 28.9 in Year 3 (P < 0.001). The all-goals attainment rate increased from 59.4% at baseline to 60.5% in Year 3, with an especially significant improvement for low-density lipoprotein (from 46.8% to 67.0%) and glycated hemoglobin (from 55.0% to 64.0%). Achievement rates decreased for hemoglobin (from 34.2% to 31.0%), calcium (from 94.6% to 92.3%) and phosphate (from 89.9% to 82.5%) between baseline and Year 3. Albuminuria was the least achieved goal (from 23.4% to 24.0%). Subgroup analysis revealed that estimated glomerular filtration rate did not decline in patients who had a good achievement rate, but decreased significantly in patients with a poor achievement rate.

Conclusion: Enrolment in CKD care programs resulted in a significant improvement in goal attainment by patients. Further, a good achievement rate was associated with better preservation of residual renal function.
