The Nephrocare project: referral, patient case-mix, follow-up and quality of renal care in Nordic renal centres.

ABSTRACT

OBJECTIVE: Few studies have focused on patients actually attending renal units for their follow-up over time. This study reports the type of prevalent patients (case-mix) with a renal condition being followed up by 19 renal units in the Nordic countries during 1998-99. MATERIAL AND METHODS: In a joint quality of care development project between the renal societies of the five Nordic countries and the unit for Quality of Health Systems, WHO (Europe), 19 renal units collected data on a random sample of their prevalent patients. RESULTS: At follow-up, 56% had chronic kidney disease (CKD) not in renal replacement therapy (RRT). Seventeen per cent had haemodialysis (HD), 6% peritoneal dialysis (PD) and 21% a functioning kidney transplant (Tx). In the CKD group, 5.9% were CKD stage 1, 17.6% stage 2, 35.2% stage 3, 25.6% stage 4 and 15.7% stage 5. One-third had known cardiovascular disease, 30% known diabetes, half had a blood pressure >140/90 mmHg and 75% > 130/80 mmHg. Twenty eight per cent had left ventricular hypertrophy, 20% were smokers and 17% were anaemic. One-third of those with known cardiovascular disease were prescribed lipid-lowering therapy and half of those with proteinuria were prescribed an angiotensin-inhibiting drug. CONCLUSIONS: The data, collected in 1998-99, indicate that there is room for improvement in the quality of care provided by renal units to patients with CKD. The data may serve as a basis for assessing possible change in nephrological practice after the introduction of K/DOQI guidelines and staging of chronic renal disease.
