Supervivencia en hemodiálisis vs. diálisis peritoneal y por transferencia de técnica. Experiencia en Ourense 1976-2012 / Survival for haemodialysis vs. peritoneal dialysis and technique transference. Experience in Ourense, Spain, from 1976 to 2012

Introducción: La supervivencia (SV) comparada en terapia renal sustitutiva (TRS) es dependiente de la comorbilidad previa al inicio de TRS y no de la técnica dialítica. Objetivo: Valorar la SV en nuestra población de TRS habida en el periodo 1976-2012 y asimismo la influencia por la transferencia de técnica (TTc). Material y métodos: Cohorte retrospectiva (n = 993 pacientes). Los datos fueron «censurados» por trasplante (TX), cambio de técnica, defunción o pérdida para el seguimiento. La SV por TTc se realizó en pacientes con más de 12 semanas de permanencia. Resultados: El riesgo de mortalidad ajustado por edad, sexo, técnica dialítica o diabetes mellitus (DM) mostró que el riesgo estimado de morir aumenta un 4,8% por cada año aumentado (HR=1,048, IC del 95%, 1,04-1,06, p<0,001) y este aumenta un 44% en los diabéticos con respecto a los no diabéticos (HR=1,44, IC del 95%, 1,16-1,76, p<0,01). En cuanto a la SV por TTc, los que inician HD presentan SV menor que los que inician DP y son transferidos a HD (p=0,00563). Conclusión: En nuestra experiencia, la SV en TRS es dependiente de la edad y la coexistencia de DM y sería conveniente retomar el concepto de «cuidados integrales» comenzado la TRS por DP y transferir a HD(AU)

Objective: To assess SV in our RRT population in the period 1976-2012 as well as the influence of technique transference (TT). Material and methods: The study included a retrospective cohort of 993 patients. Data were classified as transplant (Tx), change in technique, exitus or lost to follow-up. SV for TT was determined in patients with over 12 weeks of permanence. Results: The mortality risk adjusted for age, sex, dialysis technique or diabetes mellitus (DM) showed that the estimated risk of death increased by 4.8% per year increase (HR=1.048; 95% CI: 1.04-1.06; P<.001) and was 44% higher in diabetics compared to non-diabetics (HR=1.44; 95% CI 1.16-1.76; P<.01). Regarding SV for TT, patients who initiated HD had a shorter survival than those who initiated PD and transferred to HD(P=.00563). Conclusion: In our experience, SV in RRT is dependent on age and coexistence of DM. It would be beneficial to reinstate the concept of 'comprehensive care', in which RRT would start with PD and later transfer to HD (AU)
