Caring for hemodialysis patients in Saudi Arabia. Past, present and future

There are currently 5706 patients receiving hemodialysis therapy in the Kingdom of Saudi Arabia - a 15 fold increase when compared to 1983. The annual increase in the number of patients on dialysis for 1999 is 696 (10 fold increase when compared to 1983). Besides the massive increase in the number of patients in the last 20 years, we have noticed a marked increase in the mean age of patients (51.3 years in 1999 as compared to 37.9 years in the early 80s). Diabetes mellitus which was an insignificant contributory etiology (4%) in the early 80s is now a major cause (16-25%). Similarly mortality has increased from 4% annually to 11-14% annually. This is largely due to increasing age and prevalence of diabetes mellitus. Within the expired cohort the mean age was 62.3 years compared to 51.3 years of the total dialysis population, and diabetes mellitus was present in 60.5% in those who expired. Moreover, ischemic heart disease was diagnosed in 50% before death. Tuberculosis and Hepatitis C virus incidences, however, have not improved over the years but the degree of rehabilitation has, largely due to better hemoglobin level and due to the technological advances in dialysis delivery. This article describes these changes, their causes and implications.
