Análisis de sobrevivencia de pacientes con enfermedad renal permanente en Puerto Rico 1970-1994 / Analalysis of survival of patients with end-stage renal disease in Puerto Rico, 1970-1994

ABSTRACT

To assess the survival probabilities of patients with end stage renal disease in Puerto Rico, the data from the United States Renal Data System from 1970 through 1994 was analyzed. The Kaplan Meier method was used to determine the survival rate for the following variables diagnosis, gender, age groups, treatment modality and health regions. The analysis included 7,527 patients reported to the United States Renal Disease System of which 4,295 (57 percent) patients were reported dead. The median time of survival rate (50 percent) was 47.7 months. There was significantly lower survival rate (p = 0.0001) for diabetics compared with all the other diagnosis. Age was also a strong predictor of survival (p = 0.0001) and modality treatment (p = 0.0001). We concluded that diabetes, the elderly and the hemodialysis modality, had the lower survival rate in the puerto rican population
