Responsabilità Professionale l’essenza stessa della professione sanitaria Non è un buon segno che l’espressione «responsabilità Professionale» sia, nel comune linguaggio degli addetti ai lavori,ritenuta una mera variante semantica di «colpa professionale» La «responsabilità» è e resta una categoria pregiuridicae deontologica; rappresentando l’essenza stessa della professione sanitaria
RESPONSABILITA’PROFESSIONALE ACCEZIONE NEGATIVA Sinonimo di colpa • Valutazione a posteriori da parte di un soggetto esterno • Sanzioni • Conseguenze: esasperazione degli aspetti formali, Medicina difensiva
RESPONSABILITA’PROFESSIONALE ACCEZIONE POSITIVA PROMUOVE COMPORTAMENTI CORRETTI • CONSENTE DI EVITARE DANNI ALLA PERSONA • PRESUPPONE AUTONOMIA (CAPACITA’ DI GOVERNARSI CON LE PROPRIE LEGGI), VALUTAZIONE DA PARTE DELLO STESSO SOGGETTO AGENTE , COMPETENZA ( CAPACITA’ DI AFFRONTARE LA COMPLESSITA’ , L’IMPREVEDIBILITA’ E IL CAMBIAMENTO)
Codice Deontologico - Dicembre 2006, capo 4 (Accertamenti Diagnostici e Trattamenti Terapeutici) art. 13 (Prescrizione e Trattamento Terapeutico) Le prescrizioni e i trattamenti devono essere ispirati ad aggiornate e sperimentate acquisizioni scientifiche tenuto conto dell’ uso appropriato delle risorse, sempre perseguendo il beneficio del paziente secondo criteri di equità. Il medico è tenuto a una adeguata conoscenza della natura e degli effetti dei farmaci, delle loro indicazioni, controindicazioni, interazioni e delle reazioni individuali prevedibili, nonché delle caratteristiche di impiego dei mezzi diagnostici e terapeutici e deve adeguare, nell’interesse del paziente, le sue decisioni ai dati scientifici accreditati o alle evidenze metodologicamente fondate

GFR (ml/min) Initiation of dialysis at higher GFRs: is the apparent rising tide of early dialysis harmful or helpful? Patients starting dialysis at higher GFRs Rosansky SJ, et al. Kidney Int 2009; 76: 257-261
25% Age and comorbidity may explain the paradoxical association of an early dialysis start with poor survival eGFR >10 ml/min Lassalle M, et al. Kidney Int 2010; 77: 700-707
To examine whether the timing of the initiation of maintenance dialysis influenced survival among patients with chronic kidney disease. Primary outcome: death from any cause. — — Multicenter, randomized, controlled trial
Primary Outcome Kaplan–Meier Curves for Time to Death Cooper BA et al. N Engl J Med 2010;363:609-19
Early initiation of dialysis, which has enormous implications in terms of cost and organization, had no significant effect on clinical outcomes (rate of death from any cause, cardiovascular or infectious events or complications of dialysis) — Dialysis should not be started on the basis of an estimate of GFR alone. With careful clinical management of CKD, dialysis can be delayed for some patients until GFR drops below 7.0 ml/min or until more traditional clinical indicators for HD initiation are present — A randomized, controlled trial of early versus late initiation of dialysis Conclusions of the Authors Early initiation of dialysis had no significant effect on clinical outcomes Dialysis should not be started on the basis of GFR alone Cooper BA et al. N Engl J Med 2010;363:609-19
Lessons learnt from the IDEAL study No benefit from “early-dialysis” — Conservative therapy is possible also till GFR <10 ml/min (corresponding to 6 months dialysis delay) — Importance of close clinical follow up in non-dialysis CKD stage 5 patients — Pay more attention to patient symptoms than to eGFR — Importance of nutritional status assessment — Data from 24 hour urine collection (urea, sodium) are mandatory — It is possible to safely reduce economic burden due to earlier dialysis — Locatelli F et al. Contrib Nephrol 2011
Metabolic disturbance Malnutrition Fluid overload diuretic-refractory Uremic signs and symptoms Dialysis beginning according to international guidelines and clinical data EBPG 2005 and ERBP 2011 Theoretical lower eGFR limit K/DOQI 2006 eGFR 6 15 10 – 8 10 – 6 (ml/min/1.73 m2) CARI 2005 Locatelli F et al. Contrib Nephrol 2011
Lessons from recent trials in hemodialysis The IDEAL study: what can we learn? Even if with some limitations, the IDEAL study represents a very important trial. Its main message is the lack of a fixed GFR value at which to start dialysis in asymptomatic patients, suggesting to give more relevance to close patient monitoring (uremic signs and symptoms, fluid overload, malnutrition, etc.) This approach has been proven to be safe for the patients and effective in temporary delaying the need for dialysis — — Locatelli F et al. Contrib Nephrol 2011
European Renal Best Practice When to start dialysis: Updated guidance following publication of the Initiating Dialysis Early and Late (IDEAL) study James Tattersall, Friedo Dekker, Olof Heimbürger, Kitty Jager, Norbert Lameire, Elizabeth Lindley, Wim Van Biesen, Raymond Vanholder, Carmine Zoccali on behalf of the ERBP Advisory board. Updated guidance The 2002 guidance is not significantly changed. The evidence levels are increased by the studies published since 2002. The caution against using creatinine and CC to guide dialysis start is strengthened. A caution that eGFR calculated by the MDRD method is not useful in determining need for dialysis has been added. The emphasis on using GFR of 6 ml/min/1.73m2 as an absolute lower limit to starting dialysis is made more vague. Support for establishing advanced CKD clinics has been added.

European Renal Best Practice High-flux or low-flux dialysis: a position statement following publication of the MPO study MPO study provides sufficient evidence to upgrade the strength of guideline 2.1 to a level 1A (strong recommendation, based on high-quality evidence):high-flux HD should be used to delay long-term complications of hemodialysis in the case of high-risk patients (comparable to the low-albumin group of the MPO study) n Because the substantial reduction of an intermediate marker (beta2-microglobulin) in the high-flux group of the MPO study, synthetic high-flux membranes should be recommended even in low-risk patients (level 2b: weak recommendation, low quality evidence) n Tattersal J et al.

CONCLUSIONS • Online Haemodiafiltration, is an established RRT modality in routine clinical practice for over two decades. • Several clinical studies have reported upon the improved patient outcomes with Online Haemodiafiltration. • Ever since the DOPPS data indicating that patient high-efficiency Online Haemodiafiltration improves outcomes, the focus has been on randomised controlled trials examining the impact of high convective volumes on patient survival.
CONCLUSIONS • OL‑HDF currently represents the most technically advanced dialysis treatment available. • Widespread clinical experience with this RRT modality for ~ 3 decades has confirmed its safety and efficacy. • Widespread implementation of this technique has been delayed pending conclusive evidence of its benefits from randomized studies. The results of the ESHOL Study should be considered as an important step towards making OL‑HDF a gold standard treatment for patients with CKD. Locatelli, F. & Hörl, W. H. Nat. Rev. Nephrol.
