prevalence of patients receiving renal replacement therapy in el salvador in 2014

El Salvador has the highest renal failure mortality rate in the Americas. Five healthcare providers offer renal replacement therapy (RRT) in the country. The national RRT prevalence has never been reported. Aims: To determine the RRT prevalence in El Salvador and some basic characteristics. Methods: The association of nephrology coordinated a nationwide cross-sectional survey during the third quarter of 2014. 31 renal centres participated in the survey, covering 99.5% of patients. Results: National RRT prevalence: 595 per million population (pmp), N = 3807, average age 50.4 years old, 67.5% male. By modality: peritoneal dialysis (PD) 289 pmp, haemodialysis (HD) 233 pmp, with functioning kidney transplantation 74 pmp (living donor only). Social security covers 25% of the population but treats 49.7% of RRT patients. Generally, higher prevalence was observed in municipalities with renal centres or located on the coast or lowlands. Ninety-five per cent of HD patients receive fewer than 3 weekly sessions. Of PD patients, 59% do not belong to a continuous outpatient or automated programme, and 25% still use rigid catheter. Aetiology of chronic kidney disease: unavailable/undetermined 50%, hypertension 21.1%, diabetes 18.9%, glomerulonephritis 6.7%, obstructive causes 1.2%, tubulointerstitial 0.9%, polycystic 0.4% and other 0.7%. Discussion: Despite the increase in RRT services, the prevalence is lower than the Latin American average (660 pmp). Three quarters of HD and PD patients are under-dialysed. Obsolete RRT techniques are still used. The presence of Mesoamerican nephropathy influences the demographic characteristics (many young patients, two-thirds male, high prevalence in lowlands and coastlands).
