Pre-tertiary hospital care of patients with chronic kidney disease in India

Background & objectives: There is paucity of data available on how chronic kidney disease (CKD) is treated before referral to a tertiary hospital. This study was conducted to assess pre-tertiary hospital care of patients with CKD 5 at their presentation to nephrology services at a tertiary care hospital. Methods: Over a period of 8 months, consecutive patients with CKD 5 presenting at the Nephrology services at Christian Medical College, Vellore, Tamil Nadu, and their relatives were interviewed to assess the pre-tertiary hospital care and knowledge about CKD 5 and its treatment. Results: A total of 561 patients with CKD 5 were enrolled. The mean duration (months) of known CKD was 12.4 +/- 23.1 and known CKD 5 was 3.2 +/- 3.5. Of these, 369 patients (65.8%) had been under the care of a nephrologist; 305 patients had CKD 5 as the initial presentation of renal illness. Vaccination against hepatitis B had been initiated in only 133 patients (23.7%). Only 172 patients (38%) had an adequately controlled blood pressure. Care under a nephrologist was more likely to result in appropriate investigation, treatment and patient education though blood pressure control did not differ. Interpretation & conclusion: Paucity of symptoms in the initial stages of certain forms of CKD probably led to 50 per cent of patients presenting with CKD 5 as the initial presentation of renal disease. Inadequate vaccination against hepatitis B infection highlights the need for appropriate vaccination. Prevention of CKD and its progression are important targets which requires physician awareness at all levels. Early referral to a nephrologist's care is more likely to result in appropriate investigations and treatment.
