Background

Water is scarce in different parts of the world, including the Kingdom of Saudi Arabia (KSA). Water consumption during hemodialysis (HD) is about 360 liters/patient/week. Online hemodiafiltration (HDF) requires more water consumption (dialysate and replacement fluid) than HD/patient/week. Electricity production is interconnected with water usage. In KSA, Dialysis incidence is expected to increase on average by 5% yearly. This study quantifies local KSA utilities costs associated with in-center HD (ICHD; including High-Flux HD [HF-HD], Expanded HD [HDx], & online HDF).

Methods

Under laboratory conditions and a set treatment protocol, consumptions were recorded for power (Watt-hours, Wh) & water (Liters, L). We gathered cost data from available resources; KSA National Water Company (NWC) & Saudi Electricity Company (SEC). The results were tabulated in Microsoft Excel comparing HD modalities (HF-HD, HDF& HDx). We used single & double-pump dialysis machines (Baxter, Deerfield, IL, USA). Protocols for HF-HD, HDx, & HDF were derived from local expert opinion based on local practice. The cost of consumables & session provision per modality is assumed the same. The analysis considered the perspective of a single center with 30 dialysis beds running two shifts/day over 6 days/week at 100% capacity, caring for 120 patients/year.

Results

HDx water consumption is 3 million (m) liters and electricity consumption is 50.4m Wh/ center/year (same results for HF-HD). The total for HDF is 4.1m L & 60.2m Wh/year, respectively. HF-HD and HDx will reduce the consumption of water and electricity by 1.1m L and 9.8m Wh/year, respectively. For HF-HD and for HDx, the total cost of water & electricity consumption in US Dollars $ (USD)/center/year was $16,002.33 (USD $1 = 3.75 Saudi Riyal [SAR]). When providing HDF, water and electricity cost/center/year was $21,297.20.

Conclusion

In a typical dialysis center in Saudi Arabia, choosing to provide HDx may reduce water and electricity consumptions by $5,294.87 /year versus HDF. This significant cost savings together with the clinical benefits and ease of delivery of the HDx modality may help in favoring this therapeutic modality and strengthening economic data available to policymakers and providers.
