At present, there is no adequate system available for evaluating dialysis centres.


To construct an overall haemodialysis results weighting system, acceptable to the different stakeholders involved which allows the comparison of centres using a compound marker.


The Quality Management Work Group of the Spanish Society of Nephrology (WG) established a set of preselected indicators. A Focus Group, independent of the WG, was established. It was made up of nine individuals: three patients, three clinicians and three clinical managers, who assessed these indicators using an approved methodology and established the selected indicators. Finally, the indicators were weighted through three weighting stages, each separated by two debate periods, which involved the distribution of 100 points between each variable, according to the personal assessment and the debate sustained.


The clinical results included: haemodialysis doses, anaemia, plasma calcium and phosphorus, type of vascular access, and hospitalisation days. The weighting given to each variable following the third weighting process, expressed as an average of all the factors, was as follows: clinical results 38.9; annual mortality 25.0; satisfaction with the centre 12.2; health-related quality of life 15.6; and cost 8.3 (total 100).


The weighting structure covers relevant and overall results and includes the opinion of all stakeholders involved; all of which will increase its acceptability and widespread use and contribute to the analysis of the value produced by the centres and the improvement of the results.
