Abstract |
|---|
Background. Intermediate outcomes are associated with the survival of long-term haemodialysis patients; however, outcome variability across centres may result in heterogeneous quality of care. The study aim was to evaluate a multifaceted quality improvement activity (QIA) targeting several haemodialysis clinical performance measures.
Methods. A total (prevalent and incident) of 313 patients from four dialysis units were included. The QIA was based on a multifaceted strategy involving collection of haemodialysis clinical performance measures every 6–8 months, feedback about results, improvement plans and benchmarking, and it was tested in a 3-year prospective interventional study. Two timepoints of clinical performance measures were considered for evaluating the QIA: baseline (February 2003, pre-QIA) and final (February 2006, post-QIA).
Results. Centres showed significant improvement in percentage of patients with haemoglobin <11 g/dl, mean haemoglobin; percentage of patients with Kt/v <1.2, mean Kt/v; percentage of patients with phosphorous >5.5 mg/dl, mean phosphorous; percentage of patients with calcium phosphate product >55, mean calcium phosphate product; and percentage of patients with ferritin <200 ng/ml, mean ferritin. No change was observed in percentage of patients with haemoglobin between 11 and 13 g/dl, erythropoietin consumed; percentage of patients with ferritin <100 ng/ml; percentage of patients with ferritin >800 ng/ml; percentage of patients with albumin <3.5 g/dl, mean albumin; or percentage of native arteriovenous fistula. The percentage of patients with haemoglobin >13 g/dl was increased.
Conclusions. Quality-improvement strategies can help improve haemodialysis performance for anaemia, dialysis dose and bone metabolism. The importance of assessing patients with high haemoglobin level should be stressed.
