The joint diabetic-renal clinic in clinical practice: 10 years of data from a District General Hospital.
BACKGROUND
Diabetic nephropathy is the leading cause of end-stage renal failure. Untreated, it causes continuous decline in glomerular function, worsening hypertension and a marked increase in cardiovascular risk. Joint diabetic-renal clinics were established to address these factors and prepare patients for renal replacement therapy.


OBJECTIVE
To determine whether our joint diabetic-renal clinic influenced progression of renal disease, and whether we were able to achieve targets from clinical trials and guidelines in routine practice.


METHODS
Retrospective review.


METHODS
We collected data using clinical notes and electronic records for 130 patients attending the clinic over 10 years.


RESULTS
Our patients had 62% type 2 and 38% type 1 diabetes. Mean duration of diabetes was 24 years for type 1 and 11 years for type 2 diabetes. At referral, 56% had evidence of vascular disease and 45%, proliferative retinopathy. Baseline median creatinine was 124 micromol/l. Significant improvements were made in systolic BP, diastolic BP and cholesterol (p < 0.001), compared to measurements at presentation. We analysed progression of renal disease by linear regression on 45 patients who had follow-up data for 3 years. Rate of decline of GFR was significantly reduced from 1.09 ml/min/month in the first year to 0.39 ml/min/month in the third year, (p < 0.004).


CONCLUSIONS
Our findings suggest that the rate of deterioration of renal function can be reduced by aggressive management of risk factors. Joint diabetic-renal clinics appear to be useful in achieving targets in routine clinical practice.
