Redesigning Hemodialysis Departments to Eliminate Bottlenecks and Enhance Operational Efficiency

This article presents a new spatial layout for hemodialysis departments designed to reduce workflow bottlenecks and improve operational efficiency. The proposed design uses a compact 3×3 “airplane‑style” arrangement of dialysis stations with dual aisles and a centralized water‑drain spine. This configuration shortens nurse walking distance, improves visibility, and accelerates patient turnover. A simplified mathematical model is included to demonstrate how reductions in non‑treatment time translate into increased daily capacity. Using realistic example values, the model shows that the new layout can improve efficiency by approximately 18 percent compared to traditional linear or clustered designs. The article also provides a comparison table, discusses advantages and limitations, and outlines practical considerations for implementation in both new and renovated dialysis units. This work offers a practical engineering solution that enhances workflow, safety, and patient experience without requiring additional staff or equipment.
