#6793 TOWARDS SUSTAINABLE HEMODIALYSIS: FIRSTS STEPS TO CHANGE THE PARADIGM

Abstract Background and Aims In the field of nephrology, environmental awareness is booming we claim that it responsible for our impact. Hemodialysis treatment generates an excessive burden owing to high consumption water energy, as well production a large amount waste. On part European Kidney Health Alliance (EKHA), several proactive suggestions have been proposed worldwide. To this regard, implemented different improvements in dialysis unit, including reverse osmosis (RO) plant automation upgrade. However, change paradigm, was still necessary first know reality from which start identify opportunities improvement. The objective study determine impact care activities hemodialysis center over last 5 years. Method A retrospective analysis key indicators derived treatments, January 2018 December 2022 performed. Energy (kWh/dialysis), expenditure (L/dialysis), technical operator (TO) required time generation sanitary waste (SW, Kg/dialysis) activity were monitored according their classification: GI (unspecific non-hazardous waste), GII (patient such disposable items, used empty bloodlines hemodialyzers) GIII (sharp material, needles or anatomical waste). All these data compared with sessions carried out during analyzed period, costs calculated. Results Table 1 summarizes average generated waste, energy TO working at beginning end period. Additionally, estimated Co2 footprint each increase SW associated format presentation certain materials by producer, allowed reduction hazardous reassigned group. Regarding upgrade RO plant, slight due implementation improved sensors substantial (with 75% efficiency) prominent needed traveled distance, severely reduced addition, remotely 7101 €/year material resources 2892 €/year. Conclusion step achieving ‘green’ should be measure activity, establishing standards easily analyze possible deviation factors. Technological monitoring made more efficient overall address viability hemodialysis, need raise among professionals minimize carbon activities, designing action plans reduce as: 1. Use moderated dialyzate flows (<600 mL/min). 2. Post-treatment bloodline hemodialyzer drainage weight. 3. Initiate both campaigns specific training on correct management assess before acquisition new materials. 4. Potentiate home based treatments whenever possible.
