[Permanent renal disease in Puerto Rico, morbidity and mortality trends 1970-1994]

To describe the characteristics and trends of the incidence and mortality of End-Stage Renal Diseases (ESRD) in Puerto Rico, a descriptive analysis of the data of all patients treated with dialysis between 1970 through 1994 was conducted. A total of 7,256 patients received dialysis treatment for ESRD in Puerto Rico. Of these, 61% were males and 39% were females. Diabetes (41.7%) and glomerulonephritis (18.3) accounted for the largest number of cases followed by circulatory problems (8.3%). Hemodialysis was the predominant treatment modality (76%). The incidence trend was significant for the predictor variable period of time after adjusting by age and gender (Poisson). The mortality trend was significant for the predictor variables, period of time, gender and age (Poisson). A substantial increment in the incidence and mortality of persons receiving dialysis was found, particularly in the diabetics, males and elderly persons. The casual explanations of these findings requires further study.
