title: Challenges and limitations of maintenance hemodialysis in urban South India.
abstract: Maintenance hemodialysis is a treatment modality available to few patients reaching end-stage renal disease in India. However, the morbidity and outcome of such treatment remains largely unknown. A retrospective cohort of patients commencing hemodialysis in a secondary care institution in India between January 1, 2002 and December 31, 2004 was studied. Patient demographics, cardiac status, access, hospitalizations, and emergency room visits were assessed and outcomes determined. During the study period, 95 patients (66 males, 29 females) commenced maintenance hemodialysis. The underlying cause of chronic kidney disease was diabetic nephropathy in 66.3% of patients. Cumulative follow-up was 676+9.1 patient months. The mean serum creatinine (+SD) at initiation of dialysis was 8.39+3.28 mg%. Thirty-six percent of patients had a functioning arteriovenous fistula at commencement of dialysis, while the remaining 64% of patients required temporary access. The mean number of comorbidities was 1.9+1.0/patient; diastolic dysfunction was deemed to be present in 20.4% of the patients. The hospitalization rate was 3.9/patient year; the number of visits to the emergency room was 4.9/patient year. Cardiac pathology was the most common cause leading to hospitalization and emergency room visits. Diabetic patients were older and had higher cardiac morbidity (p<0.01). The outcome was as follows: 39% transferred to other units; 27% died; 9% switched to CAPD; 8% lost to follow-up; 1% transplantation: Kaplan-Meier survival analysis showed a median survival of 410 days. Patients commencing hemodialysis in an urban dialysis center in South India are predominantly male and have significant comorbidity including diabetes and cardiac disease. Outcome is generally poor. Hence, a huge opportunity for improvement exists.
