Can we improve our results in hemodialysis? Setting quality objectives, feedback, and benchmarking

To diminish inter centres variability in applied medical treatments, as well as in the results obtained with them, is one of the main challenges that Nephrology faces now a days. The systematic and planned use of Clinical Performance Measures (CPMs), Feedback and Benchmarking are tools that can help clinicians to reach such an objective. In this study we evaluate the consequences of applying those techniques in the results obtained in three haemodialysis units. we analyzed the results obtained in 311 patients dialyzed in the three units during the period 2006-2007. Established and evaluated objectives were as follows: 1.- To increase the percentage of patients with a serum calcium below 9,5 mg/dl over 70%; 2.- To increase the percentage of patients with a serum phosphorus under 5,5 mg/dl over 80%; 3.- To increase the percentage of patients with a serum PTH in between 150-300 pg/ml over 40%; 4.- To diminish the percentage of patients with a serum ferritine below 100 ng/ml under 10%, in one of the units that at the beginning of the study was not accomplishing that objective. Every three months each unit received their own results as well as the results of the two other units. the percentage of patients with serum calcium below 9,5 mg/dl increased significantly in the three units (54,6%, 56,1% and 55,6% at the beginning; 87,7%, 82.9% and 75,1% at the end of the study, respectively; p
