Outcome of Chronic Kidney Disease Patients on the Basis of Referral to Nephrologist: A One-Year Follow-up Study

To determine the outcome of chronic kidney disease (CKD) patients presenting for dialysis on the basis of referral to nephrologist. Observational study. Nephrology Department of King Edward Medical University/Mayo Hospital, Lahore, from January 2014 to January 2016. All patients who were presented in nephrology outpatients department and with the indication of dialysis were included in study. Patients who refused dialysis, and with acute kidney failure were excluded from the study. Proforma was designed for demographics, vital signs, volume status, and laboratory data (hemoglobin, urea, creatinine, albumin, bicarbonate etc.) of all the patients. On the basis of referral, patients were divided into two groups, i.e. early referral and late referral. Early referrals were those patients who were referred to a nephrologist more than three months before dialysis initiation. Late referrals were those patients who were referred to a nephrologist less than three months before dialysis initiation. Patients were followed up at one, three, six, and 12 months for outcome, i.e. still on dialysis or died. One hundred and seventy-six patients were enrolled in the study, and 141 were followed up to one year. Seventy- two (51.1%) patients were male, 69 (48.9%) were female and most (n=69, 48.9%) were in the middle age group. Major causes of end-stage renal disease (ESRD) were hypertension 70 (49.6%) and diabetes mellitus 66 (46.8%). Seventy-six (53.9%) patients were in fluid overload and acidotic (n=123, 87.2%). Twenty-seven (19.1%) patients were referred early and 114 (80.9%) were referred late. Overall mortality was 78 (55.3%) at one year. Factors affecting mortality were financial status and metabolic acidosis, but not referral. Temporary access for hemodialysis has 1.38 times more risk for mortality than the patients with permanent access. There is no difference on the outcome of dialysis patients on the basis referral to nephrologist. Factors affecting overall mortality in both groups were financial status, metabolic acidosis, and temporary access for dialysis. Most of the patients were referred late to the nephrologists.
