Management of hypertension in patients developing endstage renal failure

The benefits of treating hypertension include preventing or delaying the progression of chronic renal failure, and reducing the cardiovascular complications of patients with renal disease. We examined how well hypertension had been managed in all 145 patients from a single health district who started dialysis during a S-year period. Data relating to management of hypertension, including all blood pressure readings, were obtained from their general practice and hospital case notes. The anonymized data were reviewed by two independent assessors against a set of standards based on the British Hypertension Society guidelines. There was close agreement between the assessors. Complete records were obtained in 98.5% of cases. Of the 145 patients, 107 (76.4%) were hypertensive before developing end-stage renal failure. There were departures from standards in all categories of care: 24.3% in detection/diagnosis, 29% in investigation, 22.4% in referring to a nephrologist, and 17% in follow-up. The British Hypertension Society recommended standard for diastolic blood pressure of 90 mmHg was achieved in only 45%. In 32%, the assessors independently concluded that poor blood pressure control might have affected adversely the progression of renal failure. New methods of dealing with these problems are required and possible approaches are discussed.
